A Cognitive Model for Conceptual Change in Science Instruction with a Focus on Educational Software Development

Alireza Rezaei and Larry Katz

Journal of Educational Computing Research, Vol 19 No 2, 1998, p. 155-174

In this article the authors introduce the Inventive Model as a theoretical base for science instruction and for software development in science education. The Inventive Model is a constructivistic approach to conceptual change. This model is presented as a response to the urgent need for a theoretical framework for software development in the area of conceptual understanding in science and mathematics. The model is based on the theoretical works of the pioneers in the field as well as the recent innovative/effective practices in science instruction. Some components of the model have been tested successfully in the past. However, the effectiveness of the whole model needs to be tested.

Natural language understanding is a major limitation of computer-based instruction. However, in this article it is shown how simple diagnostic tests, students' log files, and other advantages of computer assisted instruction (CAI) may compensate this limitation. In ongoing research the authors are developing an instructional multimedia program for conceptual change in physics based on the model. The multimedia program can be used individually, in small groups, or by the whole class under the teacher's guidance. Qualitative and quantitative comparisons between the individualized version of the multimedia program and the traditional physics instruction are the main goals of the ongoing research.
