科学实验是教学活动的一部分,因此教师需要遵从教学的基本原则,除此之外还应遵循科学性原则、显效性原则、简明性原则、安全性原则等。教材因受材料和环境的影响,它在实验设计中也存在一定的局限性和不合理性。分析教材,运用不同的实验方法,需要对实验进行改进,帮助学生更有效地完成科学探究。
Scientific experiments are part of the teaching activities, so teachers need to follow the basic principles of teaching, in addition to follow the scientific principle, the principle of obviousness, the principle of conciseness, the principle of safety and so on. Due to the material and the environment, the textbook has some limitations and irrationality in the experimental design. Analysis of teaching materials, the use of different experimental methods, experiments need to be improved to help students more effectively complete the scientific inquiry.
