| Chemical experiment is not only the important content of chemistry teaching in senior high school, but also the important point of the college entrance examination. But in reality, the scoring rate of the experimental questions is very low. How to improve the effect of the experimental teaching,make the students master the experimental knowledge, develop experimental skills and improve the scoring rate of the experiment are the problems all chemistry teacher urgently need to solve.This study goes on under the direction of Inquiry teaching theory, Constructivism teaching theory and the teaching theory of cognitive structure in development. By the surveys of questionnaires and interviews for senior3students, I analyze the reason why the scores of students in experiments are not high; at the same time, it is pointed that there are some disadvantages in the experimental teaching of the traditional teaching, especially in the schools where the level of students is poor. By the surveys of questionnaires, I find that experimental teaching has some problems in the teaching of the senior high school chemistry teachers.In this paper, on the basis of the previous research, I put forward the teaching strategies of senior high school chemistry experiment teaching from the following six aspects:(1)Fix on textbooks, combing experimental knowledge and construct experimental framework.(2) When grouping experiments,we should pay attention to directing students (3) Focus on demonstration experiments.(4) Summarize the experimental questions of the college entrance examination, clear the direction of the examination and grasp the direction of teaching.(5) Standardize experimental expressions and standardize how to answer the questions.(6) Pay attention to training students’analytic ability, the ability of thinking and the speed of solving the questions. Through the teaching practice, I make a survey and an interview, this paper argues that the teaching strategy is effective and available. |
