摘要:The authors from Faculty of Science University of Hradec Králové prepared worksheets for teaching topic “The rainbow formation” in subject physics at high school through laboratory work, which combines classical experiment and computer model. Classical experiment can be done with tools commonly available in the school science lab. A computer model based on geometric and physical analysis of the problem is to create a table and graph through spreadsheet software. Carefully prepared worksheet was provided to several teachers at different types of high schools in Hradec Kralove and the surrounding area. Addressed teachers used the methodology and worksheets for certain groups of students. Efficiency of the method was tested by pre-test and post-test and evaluated with method of normalized gain. Each of the teachers gave both tests to experimental and control group. The results confirm the hypothesis that high school students who have completed experimental teaching of the topic of “The rainbow formation” understand optical phenomena better than students who did not pass this teaching.
