초록
The purpose of this study is to develop Slide Glass(SG) which allows elementary students to easily and effectively observe protist such as paramecium. For this purpose, the science curriculum, textbooks, and guidebooks related to the paramecium were analyzed. In addition, learning and teaching experiences on the paramecium were surveyed with 83 primary school teachers. SG, developed in this study, has a square-shaped structure for observing protist in a certain space. The SG were developed in three forms; 3D printing, acrylic processing and mesh to create a single space. SG’s size is shown in horizontal and vertical lines. The SG was tested the effects of 6 on-site primary school teachers and 96 elementary school students. The results of this study are as follows. First, the educational experience in paramecium of the elementary school teachers was low; the experience of learning was 49.4% and the experience of teaching was 24.1%. Second, elementary school teachers were having difficulty collecting (48.2%), difficulty observing (24.1 %), difficulty preparing (20.5%), and difficulty manipulating microscopes (7.2 %). Third, the developed SG was effective for elementary school students to observe the appearance, movement and size of paramecium. Finally, I hope that SG developed in this study will reduce the instructional burden of elementary school teachers and expand opportunities for elementary school students to observe directly the protist such as the paramecium.
