一、将验证性实验改为探究性实验验证性实验只是单纯的模仿和重复,不能满足学生的求知欲望.而探究性实验教学是以问题为中心的教学,有利于激发和培养学生的学习兴趣,变被动接收为主动学习.因此,在化学实验教学过程中,宜将一些验证性实验改为探究性实验.在探究性实验教学中,提出具有吸引力和挑战性的问题,使学生产生问题意识,是探究教学的关键.因此,实施探究性实验教学,首先要引导学生发现问题、提出问题.教师要根据教学目标和学生的认知 First, the verification experiment was replaced by the exploratory experiment. The verification experiment was only a simple imitation and repetition and could not satisfy the students’ desire for knowledge. The exploratory experimental teaching was a question-centered teaching, which was conducive to stimulating and cultivating the students’ interest in learning. The passive reception is changed to active learning. Therefore, in the course of chemical experiment teaching, some confirmatory experiments should be changed to exploratory experiments. In the exploratory experimental teaching, questions that are attractive and challenging are raised, causing students to have problems. Consciousness is the key to inquiry teaching. Therefore, to implement exploratory experimental teaching, we must first guide students to find problems and ask questions. Teachers should follow the teaching goals and students’ cognition.
