IN-SERVICE CHEMISTRY TEACHERS TRAINING - THE IMPACT OF INTRODUCING COMPUTER-TECHNOLOGY ON TEACHERS ATTITUDES AND CLASSROOM IMPLEMENTATION

The successful introduction of computer-aided intsruction as a tool fo r enhancing chemistry teaching depends on positive attitudes of the te achers. The research investigated the effects of in-service training a nd teachers' self-developed mini-courseware on broadening CAI use for chemistry. It involved followup of in-service teacher training aimed a t strengthening the confidence of chemistry teachers in their ability to use computers in the classroom and monitoring attitude trends. We d eveloped a CAI module on polymers, which was used to introduce the var iety of possibilities and benefits of using studyware in the current c hemistry curriculum in Israel. It was presented as a source for master y learning, enrichment material, problems and their solutions. As a re search tool, the teachers answered pre- and post-attitude questionnair es regarding the use of computers for chemistry teaching in general, a nd the polymer module in particular. The analyzed data indicated a pos itive change in teachers' attitudes toward CAI and using computers in their classrooms. As for the polymer module, the teachers indicated th at they intend to incorporate it within the chemistry curriculum mainl y due to the three-dimensional polymer models, the animation and the v isual effects that explain polymerization and stretching processes. Te achers in the experimental group implemented the polymer module either in their classrooms or by bringing the students to enrichment days.
