Making Online Courses More Accessible by Design

Many years ago, before I moved to Chicago and began working at DePaul, my supervisor at a previous job took me on a field trip to a nonprofit service organization for the blind. At that time, I had never seen someone with a serious visual impairment use a computer. I had no idea how a screen reader worked, and all my knowledge of accessibility best practices came from second-hand sources I’d found online.

At one point during our tour, we asked one of the volunteers to show us a website that was difficult for her to navigate. The site she chose contained a large navigation menu composed of at least fifteen tabs at the top of the screen. As she moved her cursor from the upper left corner across the links, each one was read aloud. She explained that, because this site had no link for keyboard users to skip the main navigation, she had to navigate through every link before she could access the more important main content below.

Once she made her way to the main content of the page, she moved from link to link, trying to find a specific document she needed to access. Each time she advanced to the next link on the page, the screen reader would read it aloud, and she would pause to listen to the first few syllables before deciding whether or not to move on. At one point, the screen reader simply said, “Click here,” and then read the URL of the link aloud, which was long and incomprehensible. Because the linked text didn’t describe what it linked to, our volunteer had to stop and listen to all of the text around the link to determine if the link would take her to the document she needed.

For some reason, this portion of the field trip stuck with me. Perhaps it was etched into my memory because it seemed like such an easy issue to fix. All the site’s author needed to do was link the actual title of the document or destination page instead of ambiguous terms like “Click here.” Or perhaps I remembered it because this small change provides two benefits. In addition to helping blind users navigate a page more quickly, clear link titles reassure all users that clicking a link should take them to a page or document with a title that matches the link. This might seem like a minor benefit, but considering how often links change and break in an online course, anything we can do to clarify where a given link should go is probably worth the extra minute it might take to reword it.

Ever since that day, I’ve tried to sing the praises of link titles that match the titles of their destinations. Of course, it’s always helpful to have a well-written piece of supporting evidence from a trusted source. So, you can imagine my joy when a friend recently sent a link to this excellent information graphic.


Source: “Web Accessibility for Designers,” Info Graphic from WebAIM.org

What I love about this info graphic is it reminds me that accessible design isn’t just beneficial for the disabled. Much of what makes content more usable for the disabled also makes it more usable for everyone. To illustrate my point, here are a few guidelines from the graphic with examples of how each one can benefit all users.

Plan heading structure early. Clear headings help break up long blocks of content into more digestible chunks, making it easier for students to take a break and pick up where they left off. They also make text easier to scan for key information when students review something they’ve already read.

Provide good contrast.  Low-contrast text isn’t just a problem for users with visual impairments or color blindness. High contrast color combinations are easier for everyone to read, particularly when text runs more than just one or two lines.

Watch the use of CAPS. In addition to creating a problem for screen readers, text in all caps is difficult to read and implies the author is shouting.

Use adequate font size. No matter how good your vision, tiny font sizes lead to eye strain and frustrate all users.

Make sure links are recognizable. Cascading style sheets make it possible to spice up a course with all sorts of unique visual formatting. However, when it comes to links, the universal standard of blue, underlined text is usually best.

While this graphic was created to highlight accessibility issues that would be most relevant for designers, there are other best practices that instructional designers have to consider. In some cases, it can be difficult to justify designing online courses with complete accessibility because it’s more cost effective to address certain issues when accommodations are needed for a specific student. Audio transcription for the hearing impaired is a common example of an accessibility feature that can be difficult to justify if a course includes a large amount of audio content, such as PowerPoint narration, YouTube clips, full-length films, or podcasts.

In some cases, it’s just not feasible to transcribe everything in advance. However, there are advantages to including transcripts in the initial course-development process even if a disabled student never requests them. For example, ESL students might read the transcript as they listen to help them identify words that were difficult to understand through audio alone. In addition, students might prefer to review a transcript when preparing for an exam instead of trying to locate the portions of a video that they need to watch again.

While it can feel overwhelming to design a course that follows every accessibility best practice, keep in mind that many are easy to follow with little extra effort, assuming you’re aware of them early on. For guidelines that feel daunting, it might make sense to accommodate disabled students on a case-by-case basis. As you evaluate each challenge and determine what merits extra effort up front, keep your audience in mind. While it’s easy to feel that all accessibility accommodations are a big investment for a relatively small group of users, the impact of many accessibility improvements are seldom limited to students with disabilities. And if you don’t believe me, just ask anyone who has pushed a baby stroller down a sidewalk in the last few decades. They can tell you how helpful curb cuts are, even though they might not realize they first appeared in Kalamazoo, Michigan, in the 1940s as an accommodation for wheelchair-bound veterans.[1] Now those helpful little ramps are a standard feature that you’ll find at either end of every crosswalk in America, and I’m grateful for them every time I take a heavy suitcase to the airport.

Do you Pin?

The first step is admitting you have a problem, but if I have an addiction to Pinterest.com, at least I’m in good company. Though Pinterest has not released its total number of users, it estimates a 329 percent increase in unique visitors from September to December 2011, and social-media agency Ignite estimates over 4 million registered users. This infographic shows Pinterest’s impact in the social commerce arena and highlights how referral traffic from Pinterest is much greater than Google+. Pinterest also just won Best New Startup at the fifth annual Crunchies awards this week.

So What is Pinterest?

The site’s About page describes Pinterest as a virtual pinboard that:

…lets you organize and share all the beautiful things you find on the web. People use pinboards to plan their weddings, decorate their homes, and organize their favorite recipes.

Best of all, you can browse pinboards created by other people. Browsing pinboards is a fun way to discover new things and get inspiration from people who share your interests.

Why Do I Pin?

So much of what we consume on the web is visual, and “pinning” an image to my board that is linked back to an original source has been a great way for me to organize different interests and areas of my life. I used to e-mail links to myself, take a picture with my phone, or in extreme circumstances print out an image. All of this information was scattered and not necessarily connected to its source if I needed further information. In addition to organizing my own life, the site helps me feel connected to my friends’ wedding plans, do-it-yourself projects, and favorite new recipes—in a more efficient and enjoyable venue than Facebook provides.

I knew Pinterest had become an extension of myself when in one day I used it:

  • on my phone to show the hair stylist a celebrity haircut I had pinned
  • on my Nook Color to pull up a healthy recipe for dinner
  • on my laptop to show my husband decorating ideas I had gathered

Does Pinterest Have a Place in Education?

While I am always eager to explore the potentials of a mainstream technology for effective use in education, I’m not yet convinced that Pinterest is a good fit, but hope to be proven wrong. Certainly for design-related coursework, or maybe a nutrition course where recipe-gathering is appropriate, Pinterest could be a natural organization solution. I am interested to know if educators are finding meaningful uses with their students, or perhaps in presenting content. I once had similar doubts about Twitter and Facebook for use in education and have since seen examples where these mainstream technologies were leveraged effectively. The way Pinterest allows users to easily connect with others who have similar passions and interests could have a place in developing professional learning networks, especially for those in creative fields. For now I will keep up my own pinning and watch to see how the increasing consumption and sharing of visual information is addressed in the education sector.

Making Online Course Development a Reality Show

A dozen years ago when I completed all the required courses and prelim exams for a doctorate, my dissertation chair, Dr. Jerry Summers, said to me, “Congratulations, Sharon! You are now on your own!”

He was alerting me that on the dissertation journey, no one else would be holding the reins for me.

Frightened by the notion of being on my own and the rumor that only 20 percent of the ABDs who left their program end up finishing their dissertation, I declined a few “outside” job offers and took a position within my alma mater. Since there wouldn’t be any reminders from my dissertation committee, I rallied up what I called a “butt-kicker committee” to check on my progress on a regular basis. It includes a mentor who ran after me every Wednesday for more chapters, a boyfriend who threatened to break up if I didn’t finish, and my parents who pressured me by cooking super nutritious meals.  

Today, when I think of that process “metacognitively,” I see that the fear of being “on my own” that triggered me to do something about it was an essential reinforcement for me to complete my degree. The danger of being on one’s own is immense—it can make a disciplined person procrastinate and a procrastinator drop off. When work and life keep presenting mini deadlines day in and day out, it is so easy to neglect the big, long-term deadline you’ve set for yourself—like getting a course ready for online delivery.

Like writing a dissertation, this “on-my-own” syndrome has been a major road block for online-course development. When a professor’s day is constantly filled up with teaching, meetings, and researching activities, that deadline for putting together a carefully designed course will likely be pushed, rushed, or expunged.

To beat the odds, a professor from DePaul’s College of Education came up with the idea of opening his course development schedule and experience to the world. On January 5, Dr. Chris Worthman published a blog post on the Center for Educational Technology’s website called . Developing a Hybrid Course: In the Beginning…. In his blog, Chris announced that he will post a weekly update on the progress of developing his hybrid course. The content, in his own words, will include “what I have done, experienced, and been thinking about; what excites me, scares me, and leaves me scratching my head; and, generally, just what this means to me professionally.

Chris’s idea of blogging his progress strikes me as such a brilliant idea—more brilliant than my butt-kicker committee (even though there were no blogs back then). I see that by turning a course-development project into a reality show, Chris sought out 1) an effective motivation strategy for himself, 2) a professional-development example for his faculty peers, and 3) a model for his students, which is the most important and cleverest aspect of it.

A Motivation-through-Visibility Strategy

As Chris mentioned in his blog, he is “in the enviable position this quarter of developing a new course for a new program that will be taught for this first time in spring 2012 as a hybrid.” Everything about this course was new—including he himself to the experience. Chris was put on a schedule by his instructional designer and initiated the blog to “hold himself to it.

If making my dissertation visible to my mentor, boyfriend, and family helped create an audience that trigged me to contribute and deliver for their readership, Chris’s action of blogging about his course surely has pushed this “audience effect” to a much higher level. Researchers have found that motivation generated through visibility has been a driving force for the success of online systems such as Wikipedia. Knowing the existence of an audience, as they found, may be sufficient to trigger contribution on its own. So, for Dr. Worthman, having to present his progress every week makes moving his work forward an inevitable action that he now owes to his readers like me. This motivation-through-visibility strategy left him no room to fall back.

A Professional-Development Example for Faculty Peers

In his blog, Chris wrote, “This will be an exercise into the unknown for me because I am not used to spilling the details of a new experience in this way. I hope, however, that it will provide others—like you—with some insight into my professional development and invite others—like you—to share your own experiences, particularly as it relates to digital technology use.”

As the director of his school’s Center for Educational Technology and the associate dean for Curriculum and Academic Programs, Chris has the responsibility of leading faculty into the new era of teaching and learning, which is heavily influenced by the use of digital technology.  When it comes online learning, faculty may have been exposed to sample courses or bits and pieces of stories shared by online-teaching veterans, but very rarely do they have the opportunity to observe the whole process and almost never do they hear the pains and gains associated with each of step of development.

From an initial pledge of doing his work openly, to toiling with Softchalk, to a metaphorical analysis of online-course development, to juggling among elements within a course, his blog brought faculty members a real picture of what it is like for a faculty member to develop a new course in a new modality under a very tight schedule.

A Role Model for Students

I always feel that higher education—as it is now designed—seems to position its faculty and students into two very discrete groups of “knowledge providers” and “knowledge seekers,” or the ones who know and the ones who don’t.

If the process of learning was a race, the only ones who are running are the students; the professors are merely standing on the side to advise and to make some judgments. Those who belong to the professor clan never get to show the ones struggling on the track how they had approached the finish line and never get to rejoin the race—well, not until they begin to learn something new—like teaching online.

When it comes to building technology competencies, online teaching provides faculty members a unique opportunity to meet their students at the starting line. Not only does it put professors in the students’ shoes but also offers students an opportunity to observe how professors conduct the race. The latter can be achieved through a very careful design, like the one Chris Workthman is trying to accomplish. By implementing project-based learning, Chris, tried to develop an authentic learning experience for his students—by letting them experience what he is experiencing. As he said, in his January 19 blog, A Few Thoughts on Process, “To a large degree, what I am experiencing in designing my course is what I want my students to experience when they develop modules on different components of the English language arts.”

Besides teaching them the way of learning, it is even more critical for a professor to cast a spiritual influence on the students, such as the attitude that one should carry in dealing with the unknown. “I want them to jump, with no fear of failure but a level of realism that suggests they are going to have to work hard,” Chris wrote. “I want them to envision themselves as teachers doing actual teacher work. I want them to have a certain level of frustration that forces them to think at a meta-level not only about what they are doing but about teaching and learning in general.”

Lee Shulman once said, “Only when we have something to value, will we have something to evaluate… and we cannot value something that we cannot share, exchange, and examine.” Yet, it takes a lot of “guts” for one to be totally open to that action of sharing, exchanging, and examining. Chris Worthman’s blog reminded me of a comment George Clooney once made on using social media: “I would rather have a rectal examination on live TV by a fellow with cold hands [than use social media].” Although it’s meant to be a celebrity’s act to defend his privacy, it also showed how hard it is for people to open up their thoughts. For this, Chris’s idea of sharing your course development stories is more than brilliant—it is very brave! I am looking forward to seeing his hybrid course lead, inspire, and transform his students into online learning troopers in the coming spring quarter.

Use EmbedPlus to Customize and Annotate Video Embeds

The most recent issue of Technology and Learning: Ideas and Tools for Ed Tech Leaders (January 2012) includes a wonderful list of their top one-hundred education websites for the classroom and beyond. While many of them are really intended for the K–12 audience, this list provides a few tools that could be of interest to instructors in Higher Ed. One in particular, a tool called EmbedPlus, seems particularly promising.

This free tool allows the user (with only the YouTube URL) to use the wizard to enhance the YouTube video by doing things like marking chapters, cropping videos, and providing the ability to view the video in slow motion.

A couple of the features that I see having real potential include the ability to annotate the video. See the example below:

Students or instructors can use this feature to provide commentary to videos. In the example above the annotated video could be embedded as the prompt in the discussion area of D2L and students could be asked to watch the video and respond to the questions posed in the video. Students could use this feature to annotate video examples demonstrating course concepts—for example the use of light in a film clip.

Another great feature is the ability to get “real-time reactions” on videos. For videos of current events and breaking news, these reactions can be used to stimulate conversation in classes. The “real-time reactions” currently come from Twitter feeds and YouTube comments. Take a look at an example from the Presidential primaries. To see the comments click on the Read icon in the bottom right-hand corner to see the comments.

I encourage folks to explore this site and see what applications you can think of. I believe this website fills a current void in the market allowing users to easily edit and share video. My hope is that more of these tools become available for other video sources (think TED videos) and that commercial providers of streaming content think about adding similar abilities to their own tool sets.

Arm Yourself with Basic HTML Knowledge

I started working in the FITS department (then called Instructional Design and Development) at DePaul as a graduate assistant, and a large percentage of my duties at the time involved moving instructor-created content from a word-processing document into the learning management system–basically, a lot of copying and pasting. But it wasn’t as easy as it sounds. Simply copying text from Microsoft Word and pasting it into Blackboard or Desire2Learn often produces strange text formatting.

These are just a few of the text formatting problems I’ve seen:

  • huge spaces between words
  • abnormally small or large text
  • seemingly random switches between serif and sans-serif fonts
  • long strings of strange xml code that are visible to students.

Other times, of course, it copies exactly as you would expect it to. In short, when you copy from a word processor into a web form, it’s very difficult to predict, even for someone who’s been at this for as long as I have, exactly what you’re going to get.

At DePaul, we have a number of instructors who are tech literate enough to want to build content for their online courses themselves but don’t know what to do when these formatting errors occur, becoming understandably frustrated.

Almost everyone is more comfortable composing their text in a word processor rather than directly in a Web interface. And I wonder if it’s time for that to change. How much of the text we produce today is going to be consumed on paper, and how much of it is going to be consumed on a screen? Should we still be teaching our students to write in a word processor, when these compatibility issues persist with Web-based writing? Should we become just as comfortable writing in the web editor as we are in the word processor?

In a perfect world, word processors would copy perfectly clean HTML into the text boxes of whatever web form they’re pasted into. But until we have a word processor from that perfect world, the brave instructor might benefit from knowing some basic HTML.

I’m not going to go through all the HTML that goes into making a website—there are great comprehensive guides elsewhere for that already. Rather, I’m going to go through some basic HTML tags that allow you to format text when you’re working in something like a learning management system.

But before I delve in, you might ask how you access the HTML for whatever you’re working on? It varies depending on what you’re working in, but in Desire2Learn, you’ll see an “Edit HTML Source” button in the lower left corner.

HTML is made up of tags, which are recognizable because they are inside angle brackets, like this: <p>. Most tags have an opening and a closing, with the content for the tag in the middle. For example <p> is placed at the start of a block of text to identify it as a normal paragraph, and </p> is placed at the end to “close” the paragraph.

These are the basic tags your content might use:

  • <p>…</p> – Paragraph
  • <h1>…</h1> – Main (page) heading
  • <h2>…</h2> – Subheading
  • <h3>…</h3> – Sub-subheading
  • <ul>…</ul> – Unordered list (bullet points)
  • <ol>…<ol> – Ordered (numbered) list
  • <li>…</li> – List item (used for each bullet or numbered item in a list. These should be nested inside a ul or ol tag.)
  • <strong>…</strong> – Bold
  • <em>…</em> – Italics
  • <a href=”[web address of link]”>text of link</a> – a link
  • <img src=”[web address of image]” /> – Image

This is an example of what clean HTML looks like, as viewed from the “View Source” button in Desire2Learn. Beneath that is an image of what actually displays when students see it. See if you can look back and forth between them and, based on the tags above, understand how the tags in the top image are producing the formatting in the bottom.

code
Click for full size

For working in a learning management system, the tags above are really all you should need. If you see any other code in the body of your html source, that’s probably what’s causing your text formatting problems. Here are some examples of things you might see that will cause formatting problems.

  • <span> – These are often created when you copy from a word processor to a web text box as the system tries to preserve exact formatting, but usually do more harm than good. Make sure you delete both the opening and closing tag.
  • &nbsp; – This isn’t an HTML tag per se. Rather, it’s displayed as an extra space. If your text is showing extra spaces, look for some of these in the body of your HTML source.
  • <font face=”font” size=”number”> – Font tags can change the font face or font size. Make sure you delete both the opening and closing tag.

Working in HTML source isn’t for everyone and certainly not every instructor, but it is a little empowering to know exactly how your web text editor of choice—not even just in Desire2Learn— functions, and be able to go into the guts of the code and manually fix that which the system broke for you.

HTML is the language in which full websites are designed, so this is obviously just the basics. But if you want to learn more HTML, there are a lot of great resources out there, the most widely recommended for beginners being w3schools.com. Maybe this will be your entry point into the wide world of making websites.

Reliving History, 140 Characters at a Time

In her October post, Emily Stone talked about using Twitter as a way to engage with her students. It allowed her to create a conversation and foster a community of sharing. These types of interactions are really Twitter’s bread-and-butter. But I’m more of a passive Twitter user. My last tweet was January 31, 2010: “really dropped the ball on this 3-d glasses thing.” (Apparently the Super Bowl halftime show that year included a 3-D component. Unfortunately I didn’t have the glasses. I cannot tell you if the show was good or not.) So don’t follow me. I won’t tweet anything. I just don’t find that I have anything really useful to say, and I’m uncomfortable “broadcasting” my thoughts. But I do log in to Twitter every day. Instead of sharing, though, I use it as another form of information gathering. I have subscribed to several feeds related to my field of study (Human-Computer Interaction/User Experience). I find it incredibly efficient and much less daunting than the 1000+ unread articles in my Google Reader, where I used to try and read articles. I think Twitter has incredible value for others who are more like me. For teachers who may not quite be ready to tweet their assignments, they too can incorporate Twitter in a passive way. Aside from subscribing to tweets related to their field to help stay current, teachers could simply point students toward some of the more engaging Twitter feeds. I found several examples re-creating historical events through “live-tweeting” (or rather the simulation of live-tweeting), which is simply Twitter’s way of reporting on key events as they happen.

Here’s a round-up of some of the more interesting historical Twitter feeds:

World War 2. Each day they tweet about things that happened on that day in 1939. It will continue for the same duration as the war: @RealTimeWWII

Extensive Civil War tweeting curated by the Washington Post. It has some live-tweeting and some quotes from famous people: @CivilWarwp/tweeting-the-civil-war

Live-tweeting the final expedition (1911) of polar explorer Robert F. Scott: @CaptainRFScott

Live-tweeting JFK’s presidency (run by the JFK Library: @JFK1962

Another WW2 live-tweet, using documents from the British National Archive and letters and memos from the UK war cabinet. This feed isn’t very accessible, though, as it just tweets links to where you can download the document in question but it is kind of a hassle to do so, especially if you are accessing Twitter on the go: @ukwarcabinet

Live-tweeting 1948 Arab-Israeli War—it’s from the Israeli point of view: @1948War

These could easily be turned into writing assignments. TwHistory helps teachers create assignments in which their students live-tweets historical events. I’m not sure how much traction this has, but it’s definitely interesting adoption of technology into education.

And for creative-writing teachers, I think one could also make the case for tweets becoming the next haiku. The 140-character limit for tweets is perfect for providing structure much in the same way as the haiku’s 5-7-5 syllabic construction.

There are also accounts that tweet out facts or tips each day. For example, someone named John Cook maintains several Twitter accounts that tweet math- and computer-science-related facts and tips, and @writing_tips posts daily writing tips. Who doesn’t need a reminder on some basic grammar every now and again?

At best I think these Twitter feeds could enhance students understanding by incorporating a technology that they use every day into their learning. At worst, they are just entertaining. And for right now, I’m really happy to be entertained by the World War II tweets. I’ve got six years to go!

Illustrative Multimedia: Meaningful Enhancement of Online Course Content

Multimedia is not a new concept. It’s been around in multifaceted forms long before learning management systems and the development of online courses came to fruition.

If asked “what’s the most popular form of media in today’s society?” one would be able to argue the Internet or television depending on your generation, technological savviness, etc. With the evolution of the Internet and the creation and mass use of online video services such as Hulu and video sharing websites such as YouTube, having access to varied forms of multimedia is becoming increasingly more common. So should professors and instructional designers incorporate multimedia from sites like these into an online course? In my humble opinion, absolutely. These sites offer content from a variety of credible entities. With course design, whether face-to-face or online, vetting what peripheral resources are included is essential.

For the purposes of this blog, let’s look at Merriam-Webster’s definition of multimedia:

  • Multimedia (noun): a technique (as the combining of sound, video, and text) for expressing ideas (as in communication, entertainment, or art) in which several media are employed; also : something (as software) using or facilitating such a technique

When developing an online course, the collective use of audio, video, and text can certainly enhance course content, but can it detract from it? I would argue yes. Clark and Mayer (2003) suggest that instead of presenting words alone, we recommend presenting words with pictures. Our recommendation is not to add pictures that decorate the page (called decorative illustrations) but instead to add pictures that help the learner understand the material (called explanative illustrations).

Being strategic is imperative not only in identifying which textbook to use, journal article to reference, or technology to incorporate into your course, but also when deciding which forms of multimedia will enhance the fundamental concept being discussed.

So, what should one consider when selecting media? The first question I would ask myself is “does the medium help illustrate and contextualize the concept(s) for a given topic?” If the answer is yes, then utilizing differentiated media can address varied learning styles. The use of audio, visual, and kinesthetic multimedia and learning activities helps to liven up the course by supporting learner engagement.

In a course that I recently developed, I had the pleasure of working with an innovative professor who identified television sitcoms and motion pictures to help articulate the course concepts. When she was unable to find existing media, this professor strategically utilized resources such as theater majors on campus to portray and video record these concepts.

There are a plethora of resources that exist on the Internet and internal resources available through most higher education institutions. The need to develop new content is unlikely given that individuals and organizations have made acquiring content much more conducive via proper permissions (i.e., creative commons, licensing rights via authentic websites, etc.) to utilize their content.

Once you have the framework of your course solidified, identifying (and in the professor’s case, creating) illustrative multimedia can help to ensure that your course content is relevant and piques students’ interest.

Designing Across Nine Time Zones: Twiddla to the Rescue!

Sometimes you need a no-cost way to work collaboratively and synchronously at a distance. For instance, earlier this year I was a member of a graduate-student team designing an interactive app for the iPad. We had a member in Saudi Arabia, another on the eastern seaboard, and several members spread across the Chicago metro area. We obviously couldn’t meet in person to sketch out ideas and critique them. We needed a way to post design documents, mark them up, and discuss in real time. Fortunately for us, we discovered Twiddla, a collaborative workspace with a free version that proved indispensible.

Getting Started

Twiddla describes itself as a real-time collaboration tool. I liked that it was simple and easy to use; just navigate to http://twiddla.com and click Start a New Meeting:

Twiddla gives you a clean, easy-to-use interface. The toolbar has controls for a virtual whiteboard, tools for adding and annotating documents, images, and web pages, and a real-time collaborative text editor that Twiddla calls an EtherPad. There’s a basic text tool for annotating the display and simple drawing and shapes tools too. Twiddla also offers some fundamental tools to edit and arrange items and a basic administrative tool that allows you to add users and edit your profile.

Once you’re in your meeting room you can edit your profile, invite other users, and load your images, documents, Web pages, or media.

Add and Mark Up Documents

My team needed to be able to see, discuss, and mark up each other’s sketches in real time. Here’s an example of a PDF uploaded to Twiddla and marked up with the drawing tool:

This ability to view and mark up sketches was invaluable to my team, allowing us to review, critique, and iterate in real time, despite being separated by thousands of miles. Twiddla now has a real-time voice tool, but we opted to use Skype for synchronous voice and created a no-cost, real-time collaborative workspace with a combination of ease-of-use and powerful visual tools I haven’t found elsewhere.

While I consider Twiddla far easier to use, more powerful, and better for my purposes than wikis, Google Docs, or Web-conferencing tools like Wimba, it also has extended functionalities like the ability to insert math formulas or upload widgets and code that make it a great collaborative tool for math, science, multimedia, or programming:

Is It Right for You?

There are of course some limitations to the free version. You don’t have a named user account, so you can’t set up a workspace far in advance and send out invitations later. You can’t hold simultaneous meetings, and you’re on your own for tech support. You also can’t archive or save your work for future use, and you can’t have a password-protected private meeting, which might preclude using Twiddla with students in some situations. Paid versions eliminate those shortcomings and add features like unlimited storage, SSL security, custom URLs, and presenter/moderator controls for as little as $14 a month.

However, the free version works really well for me. So if you’re looking for a powerful, no-cost, easy-to-use collaborative workspace, Twiddla deserves your attention. Check it out at http://twiddla.com.

Happy Holidays!

Management by Exception (MBE)

As a long-time project manager in the software engineering industry and especially during my time at Apple Computer, I’ve had to work in environments with a frenetic pace, to say the least. Limited time was available to manage multiple projects, let alone deal with the intricacies of the details. Hence, I learned early on to deal with the exceptions rather than the norms. This is a widely used management strategy called Management by Exception (MBE).

Management by Exception
Management by Exception is a “policy by which management devotes its time to investigating only those situations in which actual results differ significantly from planned results. The idea is that management should spend its valuable time concentrating on the more important items (such as shaping the company’s future strategic course). Attention is given only to material deviations requiring investigation.”
 
(from Wikipedia)

How does this relate to teaching online classes and D2L specifically? Well, D2L provides a wealth of reporting tools for tracking student progress. You can spend a lot of time and effort using these tools to track how much time a student spent in a module or on a quiz or even how long they were logged on to D2L. For example, the screenshot below shows the statistics for the time spent in a module for one particular course (the student names are omitted).

This particular module should have taken the student between 45-60 minutes to complete. Now, I could use this report to measure student engagement and perhaps even give them participation points for the time spent in the module. However, there is a big ‘gotcha’ in this report, and it relates to the little information icon at the end of all but the second line. If you click on the icon next to the first line, you get the following dialog:

This means that the student’s time in the module was not accurately reported. It is most likely because the student navigated away from the D2L module in a nonstandard fashion. They may have simply closed their browser or gone to a different webpage. In other words, they just ‘disappeared’ in D2L’s view, thus losing the ability to track their time. In reality, student #1 probably spent more time in the module than indicated in this report. On the other hand, the last student in the list spent 5 hours and 34 minutes in the module. If the student is logged into the module and goes off to make dinner leaving the browser up and running, then the time is still recorded by D2L.

So that leaves us with the question, “How should these reports be used if they are inaccurate?” It simply goes back to the original premise of management by exception. If a student is having difficulty in a class, such as poor performance on quizzes, lack of participation in a discussion, or other performance issues, you can use these reports to check how much time they were actually online. You are dealing with the exception rather than trying to use the reports for evaluating engagement of each student. Simply put, they should not be used to measure actual participation due to the inaccuracies of the report.

I suppose the best way to illustrate this is an example from an online course I taught a few years ago. This was an introductory Mathematics course and I received the following email from a student:

“I wanted to email you because I was checking my vista for homework and was disheartened to find that we had a test this coming Tuesday. I was caught off guard by this, because in our previous class we weren’t informed that we would be for sure having a test. I feel that it would be only right to let us know that there would be a test at least one class period before. I was wondering if there was anyway that we could postpone the test to review the concepts that will be on it.”

Normally, I am a really nice guy and would give consideration to a student having difficulty; however, I checked the report and found that this student had been online a total of 18 minutes during the previous two weeks! Needless to say, the test was not postponed. While I did not use the reports to measure student progress, they were helpful in dealing with this exception.

L’immersion? Mais oui!

(Listen to this entry in the Everything that FITS podcast.)

My wife and I just had the opportunity to visit Montréal over Columbus Day weekend, and it provided a nice little vacation, as well as an opportunity for me to practice my French skills. I was a little nervous at first, because although I had a French minor as an undergrad, that was twelve years ago, and I’ve had very little formal practice since. I guess that goes with speaking a language that isn’t used very much in North America, with the exception of Québec. My first attempts at speaking again were a little stumbling, as I made reservations for accommodations and tickets over the phone. I was often fishing for the right verb or term to use. However, I was really surprised at how quickly it all came back to me with only a little practice. By the second day, I was having lengthy, involved conversations with people, which I would then have to attempt to translate back to my wife. It was after having a detailed conversation about wine with a restaurant’s sommelier on Saturday night that I began to think I might not be as rusty as I’ve been telling everyone. I’d never actually talked about wine in French before, but I found myself navigating a discussion about tannins and different aromas in the wine’s nose with ease. My wife didn’t speak more than a few words of French before we went on the trip, and although she still didn’t know a lot more afterward, she speaks with a great accent.

All this was possible through the magic of language immersion. Yes, I could have brushed up on my French before the trip (and I did, a little), but this was not nearly as effective as being dropped into the streets of Montréal and knowing that we weren’t going to get directions to our next destination if I didn’t know how to ask. Being forced to practice not only what I knew how to say but also listening and responding to others in an unscripted fashion reawakened my comprehension skills. I can also say that once that switch has been flipped, it’s hard to change it back; I found myself saying “pardon” to people on the streets of Chicago instead of “excuse me” for most of the next week!

This anecdote illustrates in a concrete way the power of immersion in language learning. The fact that I could spend a weekend in Montréal and come back nearly fluent again after over a decade of very little practice shows immersion’s ability to generate near-native fluency without making the learner aware that it is happening. When you get thrown into the deep end like this, if you have the rudimentary skills necessary, most of the time you end up swimming, and swimming strongly. This was not true immersion, i.e. learning mathematics and science in French to expand my skills in math and science as well as French, but submersion; I was the foreign-language speaker with all the natives, and it was sink-or-swim. Still, it provided an opportunity to reacquire skills at a much greater rate than practicing at home.

As educators, we are constantly searching for ways to create activities and assessments in our courses that will not only challenge our students in the present but also prepare them for similar as-yet-unknown challenges in their disciplines in the future. We make them jump through hoops in our courses, believing that each hoop is getting them a little closer to our ultimate goal, that of fluency with the materials and processes at hand. However, even though we may think we are immersing our students in that world of content, we often are just giving them a boat to travel across the surface. Consider the following scenario:

A marketing professor is teaching his students about the processes involved in targeted marketing (the practice of selecting specific strategies or materials in order to best attract a particular group of individuals). His current objectives are:

  1. Students will select a group to target.
  2. Students will select a strategy to market a product to this specific group.
  3. Students will develop a marketing campaign aimed at this specific group.

Based on these objectives, it would be very possible to create an exercise in which students select a group, use some typical strategies outlined by the textbook in reaching that market, make use of instructor-provided data and generate a marketing campaign. This could even be a project that could take a whole term, depending on how the various pieces of the exercise are presented. Sounds good, right?

Let’s take another look. I spend a lot of time in this blog talking about the need for authenticity in student exercises, and this is yet another place where it’s easy to think you’re giving students a real-life, hands-on experience, when in fact you’re giving them strategies from a textbook and data from a box. Is this a good real-world exercise? Well, for the most part it is. These kinds of simulation exercises are given in many classes, and it does teach students how to process and analyze data. In many cases, this will adequately prepare students for performance in the real world, assuming that they are predominantly dealing with mostly cut-and-dry data.

However, this exercise, while it might be comprehensive, lacks the “messiness” associated with a more authentic experience. When you’re dealing with real data and real firms, things happen that you aren’t really prepared for in a “canned” exercise like I just described. Data points don’t always tell a story; sometimes they are scattered in such a way that they don’t show any relationships at all, or perhaps the data suggest a conclusion altogether different than the one students are striving to prove. Target markets change all the time, as the whims of a fickle population change. A real firm might have an enormous amount of data far in excess of what is needed or is relevant and so might require any number of weeding out processes to obtain actually usable data. Given all these possibilities, the internship model is about the truest experience out there, because it provides the opportunity to practice skills gained in class as well as to see how things actually work outside the classroom “ideal situation” bubble. However, not everyone has the time to devote to an internship in every academic program. Therefore, it is up to us as instructors to not only provide the tools to solve the problems our students will face in the real world but also to expose them as much as possible to the actual chaos that can happen within it. As much as we always try to tell our students that there are standardized procedures for everything they will face, we know that the real world doesn’t always work that way.

What does this mean for us? As we are creating assessments and exercises for our students that are supposed to be real-world simulations, we should be striving as much as possible to simulate real-world situations in their construction. Rather than giving students data from a set, show students how to obtain various data from various places and have them obtain it themselves. Have them create their own research rather than telling them what questions to ask and what data correlations to look for. In this way they can encounter the chaos they will find in the future when research and data don’t always play well together. Most importantly, giving students this more realistic experience will allow them to make mistakes. We often think that guiding students to be mistake-free will be the best learning experience, but we also know that students can learn just as much from failing and needing to come up with an alternate solution to a problem. Just because it’s real-world data doesn’t necessarily make it a real-world exercise; students need to feel like they have some ownership, and they have to be exposed to the imperfections right along with the methods.

So it’s now been a few weeks since our French immersion experience, and I can say at this point that a little refresher was just what I needed. I tried really hard to speak well, and I failed plenty during that time too. Fortunately, the locals were nice enough to correct me or suggest a different wording, but those mistakes also helped me learn even more and recall things I really shouldn’t have forgotten in the first place. My wife has been inspired to learn more French and is now doing audio lessons on her morning commute. The early immersion experience has been quite helpful to her as she navigates conversational expressions, because her ear has already been attuned to the nuances of the language; she’s getting more out of the instruction than she would if she were just presented with canned audio and conversation because she already knows how to listen to it.

Creating an immersive learning process can be tougher, messier and less predictable than just giving out textbook problems and quizzes, but real life doesn’t have a textbook, and students won’t be able to refer to a handy manual when they encounter situations they might not be prepared for. Immersion is tremendously valuable for teaching students to think on their feet and to adjust as necessary. It’s worth the extra effort on our part to help bring a little more of the outside world into the classroom, because our students will be that much better prepared to venture out into it later.
