在化学学科教学中,化学实验能使各种智力因素得到一定的训练,且也能使非智力因素有所增长,在学科教学中有重要作用.但是在对必修教材实验部分的处理中,化学教师往往会陷入各种困惑.一、我的困惑1.关于学生的实验观高中生的好奇心重,对实验充满兴趣,但这种兴趣往往停留在对新奇的实验现象的表层,无法深入到对化学知识本质的探究.在学习“金属钠的性质与应用”常态课中,笔者将两个平行班的学生做了对比.将其中一个班的学生带入实验室,先讲解课堂内容,再让学生动手实验,但在讲解过程中学生明显不
In chemistry teaching, chemical experiments can make all kinds of intelligence factors get some training, and also can make non-intelligence factors increase, which plays an important role in subject teaching.But in the processing of the experimental part of compulsory teaching materials, chemistry Teachers often fall into all sorts of puzzles.One, my confusion 1. On the experimental view of students The curiosity of high school students, full of interest in the experiment, but this interest tends to stay in the surface of the experimental phenomenon of novelty, can not go deep into In the study of the nature and application of metal sodium, the author compares the two parallel classes of students.One of the students in one class was brought into the laboratory to explain the contents of the class first, Let the students experiment, but in the process of explaining the students obviously not
