自制“热传导”实验的教具

Self-Made Teaching Aids for the “Heat Conduction” Experiment

摘要: 在小学科学教学中，使用自制教具有助于将教学中的抽象的科学概念或科学规律具体化,使得学生的动手能力、实验操作水平有所提升，有助于激发学生的科学学习兴趣。为此针对热传导实验教具进行了二度开发，使其具有直观性、美观性、安全性。该教具利用生活中常见材料完成制作，帮助学生构建起科学与生活之间的联系，同时实验结论由定性转向定量，不仅帮助学生更好了解热传导知识，还为学生步入初中学习热知识做铺垫。

Abstract: In primary school science teaching, the use of homemade teaching aids can help to make the ab-stract scientific concepts or scientific laws concrete, so that the students’ hands-on ability, the level of experimental operation has been improved. The use of homemade teaching aids in primary school science teaching helps to concretise the abstract scientific concepts or scientific laws in teaching, makes students’ hands-on ability and experimental operation level improved, and helps to stimulate students’ interest in science learning. For this reason, the teaching aids for heat conduction experiment are developed in the second degree. The teaching aids are developed to be intuitive, beautiful and safe. The teaching aids are made of common materials in daily life, which help students build up the connection between science and life. At the same time, the conclusion of the experiment is shifted from qualitative to quantitative, which not only helps students to better understand the knowledge of heat conduction, but also paves the way for students to learn heat knowledge in junior high school.
