Collaborative Use of Mathematical Content Generated by CindyJS on Tablets

CindyJS is a system which enables researchers and learners to interactively handle mathematical models on browsers. Though the enhancement of mathematical user interfaces is widely anticipated and promoted so that mathematical models can be handled via familiar web and mobile devices, it seems that the resulting realities and benefits have not yet been fully investigated. In particular, for educational use, more precise knowledge about them will likely help maximize the effect of using newly developed systems. This research is mainly concerned with the comparison between individual use and group use of CindyJS content on tablets. It can be assumed that, in the case of group use, communication between members would give some influence on the strategy of their handling of mathematical models. To investigate how members of a group influence each other’s handling of mathematical models when using CindyJS, we tracked some characteristic quantities from the recorded processes of users’ operations. Through statistical analysis (approximation with finite mixture of beta distributions) of the quantities derived from the cases of individual use and group use respectively, it can be shown that the difference between these two cases is visualized and the above mentioned influence is illustrated.
