中学校家庭科の衣服の学習において、繊維素材の吸水性と速乾性に関わる性質の理解に役立つ実験教材を提案・検討した。実験教材として布への滴下法(JIS L 1907)の改良型である肌への滴下法、およびpH 指示薬を使用した変色法(速乾性試験)を考案し、それらの評価のための授業実践を行った。実践では対象試料を綿布とポリエステル布に限定した。実験方法および授業者の違いを比較するため4クラスを2クラスずつに分け、それぞれの方法を用いて授業を実施した。また、教材の有用性評価は授業前後の質問紙調査によって行った。授業後には吸水性や速乾性における質問への正答率が上昇した。また、肌に残る汗の量に関する質問では、布への滴下法よりも肌への滴下法を用いたクラスで正答率が高かった。視覚だけではなく肌で感じることで、素材の吸水性への理解が深まり、吸水されずに肌に残留する水分を意識させることができたと考えられる。生徒の自由記述には授業内容を踏まえて着装に関する考察がみられたことから、開発教材は各自の衣生活と素材の性質を関連させて捉えさせるうえで有用であることが示唆された。なお、授業者の教師経験年数が短い場合でも、同等もしくはそれ以上の学習効果を得ることができた。
The new teaching materials in the clothing content of home economics in junior high school has introduced in this study. Understanding of the property of textile materials about water absorptivity and quick-drying are helpful to consider clothing comfort and to be able to select clothing materials appropriately. The devised experiment teaching materials were the “dripping method to the skin”, which is the improved model of the dripping method to cloth, and the“change of color method” using the pH indicator (quick-drying examination). Cotton and polyester fabric used for class practice. For four classes divided into two groups, we carried it out using each teaching materials in each classes to compare the difference of teacher and experimental method. To evaluate of usefulness of the teaching materials the inventory survey was conducted before and after the classes. The correct answer rate to the question in water absorptivity and quick-drying after the class are higher in comparison with before the class. The correct answer rate to the question about the quantity of sweat left on the skin was higher in the class dripping method to skin than the class using the dripping method to cloth. In this case, the dropping method to skin was provided understanding the water absorptivity of the material not only by the eyes but also by the conscious of water remaining on skin without being absorbed cloth. In the free description, some students look toward their future lives for a better clothing life based on the learning. Consequently, the teaching materials are useful to learn the necessity of the textile property to utilizing clothing in a planned manner. By using the new teaching materials, the little experienced teacher showed equal to or higher teaching effect than experienced teacher.
