Research On The Compilation Of High School Chemistry Exercises Based On Discipline Ability

The goal of education is to enable people to develop comprehensively and freely,and the cultivation of their abilities is the core content.Exercises in the teaching process are an important form of organizing students to study and carry out practical activities,and bear the function of cultivating students' scientific literacy and academic abilities.However,the existing exercises have always been a relatively backward and weak link in the curriculum reform and can not meet the requirements of curriculum reform in cultivating students' abilities.This article summarizes the domestic and international curriculum standards as well as the domestic college entrance examination outline,the division of the domestic academic ability of chemistry subject,and so on,to extract the five abilities of chemistry subject ability: conceptual understanding ability,symbol characterization ability,model construction ability,experimental inquiry ability and quantitative calculation ability.Based on this subject ability,the ability to sub-level,as the exercise preparation standards.Starting from the research status of high school chemistry study,using some methods such as literature survey and questionnaire survey,we analyze some questions of high school chemistry compulsory teaching materials from the questions,quantity,content and so on,and choose a certain school to carry out compulsory Textbook exercises using the survey,the results were analyzed and summarized,combined with the literature,derived from the principles of exercises and discipline ability of the characteristics of chemical exercises,based on the preparation of "nonmetal and its compounds" chapter exercises,hoping to provide a reference for the preparation of chemical exercises in high school.The research indicates:First,the content of the exercises should be based on textbooks,highlighting the foundation,examining students' ability to apply knowledge comprehensively,focusing on the extension of knowledge and emphasizing innovation.Second,the issue of setting,focusing on knowledge transfer,a certain amount of thinking capacity to grasp the depth of exercises,reflecting the extension of knowledge;answer to the title should not be set too absolute or unique,to have a multi-directionaland open characteristics,reflecting the individual level of development of student thinking.Third,the functional aspects of the exercises focus on the cultivation of students' abilities in chemistry,emphasizing the ability of students to comprehensively analyze and solve problems from a chemical perspective,and train students' scientific literacy through experiments.
