The use of interactive multimedia to promote students` understanding of science concepts and generic science skills

Multimedia plays an increasing role in education, especially in science instruction. Unlike the conventional teaching media, multimedia allows flexible combination of different modes of representation, such as written texts, pictures, animations, and sound. Using multimedia, teachers can use a combination of pictures and texts to explain a complex structure. Multimedia also allows a simulation of complex processes in simpler forms of animations. The research results reported here represent the first year results of a three-year research project, which aims at developing a Web-based instruction utilizing multimedia. The aim of the first year is to develop multimedia, and to analyze its impact on the improvement of students` understanding of science concepts, and on the improvement of their generic skills. This study finds that the use of multimedia in science instruction can promote students` understanding of science concepts. Relativity high gains were observed in biology lessons (junior high school) and chemistry lessons (senior high school), while a mediocre impact was observed in the thermodynamics course (pre-service teacher training) and magnetic induction course (in-service teacher trainig). The use of multimedia in instruction also promotes the participants` generic science skills.
