从有效的课堂教学出发,分析出现在初中化学实验教学与课堂理论中的影响有效教学的难题和缺陷,从而总结出提升初中化学课堂教学有效性的教学反思、探究教学、教学组织以及兴趣导向策略等,以此提高初中生学习化学知识的效果。下面谈几点认识。一、分析课堂教学的有效性1.教学有效性的含义。广义的有效性是指实验假设与实际的试验结果的相似程度,而课堂教学的有效性指的是学生在接受课堂学习之后所取得的进步的程度。换言
From the effective classroom teaching, the author analyzes the problems and flaws that affect effective teaching in chemistry experiment teaching and classroom theory of junior high school, and then concludes the teaching reflection, the teaching organization, the interest-oriented strategy of enhancing the effectiveness of junior high school chemistry classroom teaching Etc., in order to improve the junior high school students learn the effect of chemical knowledge. Here to talk about some understanding. First, analyze the effectiveness of classroom teaching 1. The significance of teaching effectiveness. The generalized validity refers to the similarity between the experimental hypothesis and the actual experimental result, and the validity of the classroom teaching refers to the degree of progress made by the students after they receive the classroom learning. In other words
