In two case studies, we identify multiple instances of students generating analogies, extreme cases, and Gedanken experiments and document their predominant association with spontaneous depictive gestures. Most were associated with gestures that appeared to depict motion or force, which are interpreted here as indicators of the use of animated mental imagery. We believe these issues warrant further study because it is possible that these processes, along with depictive gestures, allow students to share visual or kinesthetic meanings situated in exemplars in a way that allows the discussion to make sense to a greater number of students.</p> </div> <table id="attachments" class="sticky-enabled"> <thead><tr><th>Attachment</th><th>Size</th> </tr></thead> <tbody> <tr class="odd"><td><a href="">Complete conference paper (PDF)</a></td><td>1.87 MB</td> </tr> </tbody> </table> case studies expert-novice gesture high school imagery non-formal reasoning physics videotape analysis Tue, 13 Apr 2010 00:09:22 +0000 lstephens 476 at
