一、小实验的特点1.灵活性强,运用方便。小实验由课内小实验和课外小实验组成。课内小实验是穿插在课堂教学过程中的学生小实验,它与演示实验的不同点主要在它的操作者不是教师或者是协助教师的个别学生而是全体学生。它与学生分组实验的不同,它不像学生分组实验那样用整节课比较规范地完成教师在实验室中准备好的实验。通常它与教师的讲解密切配合,比较小型灵活,运用方便。课外小实验具有较强的自主性、灵活性和趣味性,它不受时间和地点的限制,可以利用日常生活中的常用物品和工具,学生观察操作都比较自由。
First, the characteristics of a small experiment 1. Flexibility, easy to use. Small experiment consists of small experiment and extracurricular experiment. The small experiment in class is a small experiment of students interspersed in the process of classroom teaching. The difference between experiment and experiment is mainly that the students are not the teachers or the individual students who assist the teachers. It is different from the student grouping experiment, which does not use the entire class as the student grouping experiment to complete the teacher’s experiment in the laboratory. Usually it works closely with teachers’ explanations, is small and flexible, and easy to use. Extracurricular small experiment with strong autonomy, flexibility and interest, it is not subject to time and place restrictions, you can use the daily life of common objects and tools, students are more free observation operation.
