Demonstration in Teaching Chemistry: The Case of Two High-Schools from Sarajevo Canton

For understanding fundamental chemical principles and gaining knowledge in chemistry, observation of chemical changes during experiment are crucial. Demonstration in teaching chemistry is particularly important in primary school where students meet chemistry for the first time, but also in secondary school for more demanding and complicated experiments. This study included 60 secondary school students from two schools in Sarajevo region. We have used test of knowledge regarding demonstration experiments prescribed by Curriculum, and questionnaire for students regarding the frequency of performed experiments. Results of this study showed that teachers performed experiments prescribed by Curriculum for 1st semester of 1st grade, and those students mostly do remember what happened during experiments; results of questionnaire showed that experiments in these two schools are performed on regular basis and that students and teachers recognize the importance of demonstration in chemistry.
