| Abstract | Chemation, a simple 2-D modeling and animation tool for handhelds (e.g., Palm OS computers), was developed to help teach important chemistry concepts such as chemical reaction, conservation of mass, and the particulate nature of matter. Developing this tool required a learner-centered design approach. A deeper look at learner activities, goals and context helped to define the different types of support that needed to be included. This paper describes our design process including the analysis of the learning goals, context and learner needs which led to specific design requirements for Chemation. Finally, we describe our evaluation of Chemation. Analysis of student interviews revealed that while Chemation was successful in supporting students with respect to some learning goals (e.g., animation of atom rearrangement to support distinction between chemical and physical processes), it also failed to support others (e.g., no support for distinction between substances and mixtures). Classroom observations revealed some potential usability problems (e.g., the varying quality of student animations). Plans are under way to revise Chemation in accordance with the design recommendations from this initial study and reevaluate Chemation in the classroom. |
