Teaching Strategies And Practical Research On High School Chemistry Computing Problems

Chemistry calculation is one of the important tasks of chemistry learning in high school and one of the difficult points in teaching.Computational questions require students 'comprehensive ability,which requires students to master both the basic knowledge of high school chemistry and certain computational skills.Most students will spend a long time on the part of the calculation questions in the exam.If students can flexibly grasp the solution strategies of the chemical calculation questions,they will "twice the result with half the effort" when answering the questions.This article is mainly divided into the following four parts:Part I: Research background.According to the current situation of senior high school students in solving computational problems,this paper mainly studies the syllabus of college entrance examination in chemistry,the contents of chemistry calculation in the past three years and related literature.The second part: The teaching strategy of high school chemistry computation problems.This part mainly introduces the function of teaching strategies for chemical computing problems.In order to improve the efficiency of students 'solving problems,several common solving methods and techniques are proposed,as well as several theoretical foundations involved in teachers' teaching strategies for chemical computing problems.The third part: Experimental research on teaching strategies of high school chemistry calculation problems.The study mainly focuses on the study of high school students in chemical computing problems.Through literature research methods,questionnaire methods,and case teaching methods,comparative experiments are conducted with the example of "electronic failure" and "extreme value method".The experimental results are discussed and analyzed in detail.Part IV: Conclusion.By putting forward the teaching strategy of chemical calculation problems,we can draw a conclusion that there are universal problems in chemical calculation among senior high school students,mainly because they can not master effective problem solving methods in calculation.The teaching strategies of chemical calculation problems can solve the problem of students' problem solving efficiency.Some suggestions are also put forward for the training of students' problem solving thinking and the teaching of front-line teachers.
