|
In this study, the teaching methods of three science teachers for lead-iodide precipitation reaction experiment were compared. The difference of 9th grade students’ understanding was searched according to the science teachers’ teaching styles, also. Among the three teachers, Teacher A taught students based on the science textbook and allowed students to think themselves and to get out conclusion by the experiment. Teacher B and Teacher C gave students a lot of explanations related to interpretation of the experiment. The percentage of no response on the experiment report of Teacher A was higher than those of Teacher B and Teacher C. But the students of Teacher B and Teacher C tended to have limited thoughts because of the teachers’ explanations. In spite of the difference, it was common phenomenon that few students understood concepts through the experiment. A lot of students were interested in the experiment, but it was hard to understand ‘Law of definite proportions’ according to the experiment.
