实验是学习科学的基础,但复习中部分教师还是将知识和技能从实验中剥离了出来,课堂里没了实验的踪影,有的只是反复的讲与练。这种没了以实验为基础的复习,课堂是枯燥的,效率是低下的。实验既然是学科的特色,复习当然也得以实验为基础。在所学的实验中,一些实验是教学的核心,它们承载着很多的知识点;一些实验具有典型的学科代表性,它们注重操作技能的训练;一些实验探究性突出,同时也是考试的热点;一些实验学生认知不完善,犯错多多。这些各具特色的实验正是我们复习的基石,我们若能有侧重地利用是有助于提高复习效率的。
Experiments are the basis of learning science, but some teachers in the review or knowledge and skills from the experiment stripped out of the classroom, no trace of the experiment, and some just say and practice repeatedly. Without this experiment-based review, the classroom is boring and inefficient. Since the experiment is the specialty of the discipline, the review of course can also be based on experiments. In experiments, some experiments are the core of teaching, they carry a lot of knowledge points; some experiments are typical of the discipline, they focus on the training of operational skills; some of the experimental inquiry prominence, but also the hottest examinations; Some experimental students have imperfect knowledge and make a lot of mistakes. These distinctive experiments are just the cornerstone of our review. If we can use it emphatically, it will help improve the efficiency of the review.
