검정 초등과학 교과서에 도입된 액체에서 열의 이동 실험에 대한 교사와 학생의 인식과 선호도 분석

Abstract

In this study, the perceptions and preferences of teachers and students regarding heat transfer experiments in liquids, as introduced in nine kinds of certified science textbooks for 5th grade elementary school students according to the 2015 revised curriculum, were analyzed. Experiments on heat transfer experiments were categorized into four types according to the primary heat source and the type and amount of liquid. Perceptions and preferences of teachers regarding the convenience of observation, safety of experiments, students' interest, and ease of experiment preparation were surveyed for the four types of experiments. Based on the high ratings given by teachers, three types of experiments were selected. Students were allowed to experience all selected experiments and then their perceptions and preferences were also surveyed. In terms of convenience and interest in observation, students preferred conducting experiments by heating the edges of a beaker using a gas burner. The experiment involving the heating of a small plastic container with hot water received high ratings for safety and ease of experiment preparation. In experiments involving the heating process, both teachers and students considered convenience of observation as the most important factor. However, as the next important factor, it was investigated that teachers considered the safety and convenience of preparation for the experiment, while students considered their interest in the experiment and the convenience of preparation.
