一、问题的提出在教学改革中,我力图培养学生的能力,特别是采用以化学实验为基础的知能培养相结合的教学方法组织课堂教学,其结果能否改变“高分低能”现象?学生的知能间关系是如何分布的?对此,我采用教学科研的实验方法,从实验的事实出发,作理论的分析,从而获得比较逼近事实的回答。二、实验的目的1.研究知能相结合的教学方法对学生学 First, the problem raised in the teaching reform, I try to cultivate students’ abilities, especially the use of chemical experiments based on knowledge and training combined teaching methods organized classroom teaching, the results can change the “high scores low energy” phenomenon? How is the relationship between knowledge and knowledge distributed? For this reason, I use the experimental method of teaching and research, proceed from the facts of the experiment, and make a theoretical analysis to obtain answers that are closer to the facts. Second, the purpose of the experiment 1. To study the combination of teaching and learning methods for student learning
