Research On The Construction Of Proposition System Of Inorganic Process Problem And Teaching Practice

The evaluation system of Chinese college entrance examination puts forward the requirement of "one core,four layers and four wings" to the proposition.The inorganic process problem is the key question type of "four layers" and"four wings" based on the real problem situation.The construction and teaching practice of propositional system of inorganic technological process are of great value for guiding teaching,promoting students' development and improving teachers' professional level.Based on "Evaluation System of Chinese College Entrance Examination ","Description of Evaluation System of Chinese College Entrance Examination"," General High School Chemistry Curriculum Standard(2017 Edition)"," General College Enrollment National Unified Examination Outline" and "General College Enrollment National Unified Examination Outline ",and" General College Enrollment National Unified Examination Outline ",this paper puts forward the proposition principle of inorganic technological process including science,authenticity,validity,balance,simplicity and thought on the basis of extensive literature review and comparative analysis of comparative analysis of the comprehensive chemical inorganic process questions in the national college entrance examination,In this paper,an evaluation tool for propositional problems of inorganic process is designed,which includes situation type,examination content,examination requirement and academic quality level.Thus,a propositional system including propositional principle,propositional evaluation tool,propositional strategy and propositional model is constructed.This paper carries on the proposition practice research according to the constructed proposition system,and carries on the test and the data analysis with the help of the original test question of the proposition system,demonstrates the value of the proposition system,finds out the related problems existing in teaching and learning,and puts forward some suggestions for improving teaching.Through the teaching practice based on problem solving and the test and data analysis after the special topic review class,this paper puts forward the value and significance that the proposition can guide the teaching improvement and promote the students' all-round development.In this paper,the proposition system of inorganic process problem is constructed,which provides a reference for teachers to make inorganic process problem.At the same time,through practical research,it is found that the problem of autonomous inorganic process can develop students' key ability and subject accomplishment,and realize the goal of effective teaching and quality education.
