Progressive Disclosure and Animations in DyKnow: Part 1

Wednesday, September 9, 2009 by Joel Dart
I've been talking a little about the coming PowerPoint integration that is currently in Beta and have already discussed Polls (probably my favorite part of this integration).  I would also like to touch on another important part of our enhancements to our PowerPoint import: animations.  

One of the terms that I hear a great deal when discussing pedagogical strategies is "progressive disclosure."  Dr. Dave Berque discusses this technique in his 2006 whitepaper evaluation of DyKnow usage at DePauw on page four: "DyKnow teachers often share prepared content with students following a 'pause, practice, and disclose' pattern that we call progressive disclosure."  When talking about a topic, you introduce a topic, have students engage the topic through some activity, and then reveal a sample solution.  The critical part of this, in my opinion, is the engagement through the activity, but another important element is that you are able to choose when students are given what information.

Control of information has always been available from panel to panel, as Dr. Berque was discussing.  The moderator in a DyKnow Session can choose when and in what order your prepared panels are shared with students.  And on a given panel, you could always delay writing with your pen on the panel.  However, to delay textual information or images, users often had to go to more elaborate lengths such as using white ink to cover over text and erasing at a certain time.  

With the coming integration, DyKnow will convert your PowerPoint animations to help facilitate progressive disclosure of text or images on a given panel.  
Then when you're in your DyKnow Session, click on the Append Prepared Panel/Advance Animation button (the page with squiggles and the green plus button you use to bring in your next prepared panel) and it will bring in the next animation.  Additionally, we realized many users are used to advancing animations by hitting the space bar.  Now, the space bar is hooked up to this button to give a very natural way to move through your panels like you might have in PowerPoint.  Finally, after the collaborative notetaking experience, students can replay the notebook with all the animations and their own notes synched up with the audio from the lecture (provided you choose to use it for that class).
