Interactive drawing tools to support modeling of dynamic systems

Abstract: Students may produce simple drawings that are similar in appearance (Figure 4) but mask wildly different mental models of the circulatory system.Figure 4a (Student A27) shows arrows entering the right and left atria at the top and arrows exiting the ventricles at the bottom.While pointing gestures index drawn and labeled elements such as the chambers and walls, no explanation of a time-varying process is provided, resulting in a very low score for the model (2 points out of 6).In contrast, Figure 4b (Student A14) shows a very similar drawing, with less detail (no labels) but through gesture and speech provides a rich account of the blood flow following two distinct pathways (from heart to lungs and back, and from heart to body and back) that receives a high score (6 out of 6 points).M)$ L/06-"$ I4$ )5*.)E$MNI3)$ 0")#6-")$ ,(&%1/4%''($ )/16'%#"$ 9'**,$ +'*.$ #*$ components of the system (e.g., lungs, body) that are not present in the drawing, but are invoked by gestures that move beyond the boundaries of the page.
