代用ﾃﾞﾝﾌﾟﾝを用いただ液の働き実験を、中学校理科教諭の8名によって授業実践を行い、現場教員の意見調査とともに、生徒へのｱﾝｹｰﾄによって、本授業実践の有効性の検証を試みた。本授業実践後に生徒の学習効果を検証するために、平成15年度狂句状況調査とほぼ同様の問題を解かせたところ、正答率が上昇した。We used a novel dextrin as a substitute starch on the experiments for learning of salivary function. After science classes with the experiments, we had questionnaire to the students. Analysis of the questionnaire showed easiness and safety of the experiments, reduction of resistance on collection of saliva, and getting realistic understanding due to the color change of the reaction mixtures. Another analysis of questionnaire to the teachers who conducted the science classes, indicated eagerly action of students to the science classes, and much time for discussion of the students on the experiments and salivary function. Those students were tested on the understanding of salivary function and showed increased understanding compared to the results of the 2003 Investigation by the government of course of study enforcement situation.
