学好化学概念是打好中学化学学科的基础。它是中学生学习化学的前提,概念教学也一直是中学化学教学中的重中之重,同时也是学生学习的难点,同化论是非常重视认知理念在中学化学教学中的转变。一、认知同化论的有关理论基础认知同化论的重要内容是学生对于全新知识的驾驭首先要决定于学生自身认识结构存在的相关概念,这当中意义学习的出现是由于学习的全新的知识和学生已经驾驭的概念存在的相互作用,相互作用的最后的结果可以使学生对于新老知识详细的意义实行合理的同化。在奥苏贝尔提出的理论中,把意义学习的条件规定 Learning the chemistry concept is the foundation for the chemistry discipline in middle school. It is a prerequisite for middle school students to learn chemistry, and concept teaching has always been a top priority in chemistry teaching in middle schools. It is also a difficult point for students to learn. Assimilation theory attaches great importance to the change of cognitive concepts in chemistry teaching in middle schools. First, the theoretical basis of cognitive assimilation theory The important part of cognitive assimilation theory is that students’ control of new knowledge must first decide on the relevant concepts of the students’ own cognitive structure. The emergence of meaning learning is due to the new knowledge of learning. The interaction with the concepts that the student has already mastered, the final result of the interaction can enable the student to carry out reasonable assimilation of the detailed meaning of the old and new knowledge. In the theory proposed by Ausubel, the conditions for the learning of meaning
