A Case Study of Science Class with a Slide-Show-Type Visual Aid Growing Scientific Viewpoint and Its Application to the Third Grade Pupils in an Elementary School

In this study we have developed a new slide-show type visual aid, in which five-photographs of two plants（Veronica persica and Lamium purpureum ）and an anthropod（Armadillidium vulgare ）are presented in the order of decreasing magnification. Our new visual aid was used in science class to one experimental group of third graders at a public elementary school. The conventional photographs taken from a textbook were used to the other control group of the same grades. The results from questionnaires against pupils and analysis of protocol in the science class revealed the following four points. 1） Our new visual aid grew pupils wills to learn much more about plants and insects. 2） The sketches of pupils became finer, as such leaf hairs and veins were depicted, after the lecture using our new visual aid. 3） The talks of pupils are scientific in the experimental group, while those are based on their experiences in the control group. 4） Almost all pupils in the experimental group thought that our new visual aid is useful to them, because pupils pointed out our visual aid is easy to understand and our new visual aid is attractive with the first experience in their life. It is thus suggested that our new visual aid is an effective teaching tool for pupils to learn how to observe plants and insects.departmental bulletin pape
