Investigation And Practice Research On Current Situation Of Chemistry Preview In Senior High School Students

High school chemistry curriculum standards(2017)clearly put forward to change the learning style of students is the basic requirement of the curriculum reform.For teachers to update the concept of teaching,to guide students'autonomous learning in teaching,inquiry learning and cooperative learning,help students learn,the formation of lifelong learning,active learning awareness.Class is an important part of the teaching process and learning process,but also the development of students autonomous learning,finding the important process of learning and inquiry learning ability,however,which is the most important part in the practical teaching of teachers and students did not cause the corresponding attention,even many teachers think that students' homework The heavy task,no time to prepare lessons for the students,the teacher will say,not indifferent.Preview for chemical can not only help students advance with classroom learning content,but also can let the student in the chemistry classroom and accurately find the emphasis and difficulty of lectures efficiency multiplier.Analysis and practical research in chemistry class of senior high school students preview the situation is the research and analysis of the typical problems in China's basic education based on this topic,from the following aspects of theories and empirical research.The introduction gives the background of the topic,from theory and practice.Secondly,it analyzes the current situation of preview in different teaching modes and points out that the current teaching models in most schools are still more traditional.Then,through the analysis of the current situation of chemistry preview at home and abroad,Finally,it explains the research methods and the research framework.The second part is an overview of the concept and basic theory of preview,and introduces the connotation and theoretical basis of preview.It provides theoretical support for this paper.The third part and the 4th part are the main part of this paper.In the part of practical research,through the investigation of some senior high school students'chemistry preview before class,through questionnaire data analysis and interview,we find the problems existing in the preparation process.And put forward the relevant countermeasures according to the problem and put into practice research.Part 5th is the conclusion and prospect part of this topic,is the last part of this paper,based on the current situation analysis and practical research situation.The shortcomings of the research process are reviewed,and the future research is prospected.In this paper,the present situation of chemistry preview is investigated,and the improved strategies are put into practical teaching,and the questions in the research process are also asked.It provides a reference for chemistry teachers and students to improve the efficiency of chemistry preparation before class.
