Practical Research On The Chemistry Unit Review Class With The Theme Of Life-oriented Problem Solving

Today’s fierce social competition environment and new curriculum standards have put forward higher requirements for the development of students’ abilities.The ultimate goal of attaching importance to the development of students’ abilities is to adapt to society and life better.However,as far as the current teaching status of chemistry unit review courses is concerned,it is not closely related to life,cannot stimulate students’ enthusiasm in class,ignores the development of students’ abilities,and students cannot apply what they have learned.Therefore,this thesis is based on the teaching of"problems",integrating "problems" into "life-oriented" elements,and applying "life-oriented problems"to the review class of chemistry unit,aiming to improve students’ enthusiasm in class and give full play to their main role and improve students’ practical problem-solving ability and help students apply what they have learned.This thesis consists of the following six parts:Part Ⅰ:Overview of the thesis.Introduce the research background,understand the research status of life-oriented teaching,problem-solving teaching and chemistry unit review courses by consulting the literature,and define research purpose,significance,methods and ideas.Part Ⅱ:Definition of core concepts and related theories.Through consulting related literature,be sure the core concepts of "life-oriented teaching"," living problem ","problem solving teaching" and"chemistry unit review class" were defined,and their relevant theories were summarized to provide a sufficient theoretical basis for this research.Part Ⅲ:The construction of the teaching model of life-oriented problem solving.First,select three classes in the ninth grade of the practice school randomly,and conduct a questionnaire survey on the use of chemistry unit review courses,student attitudes to class,and the impact on students’ abilities.After processing and analyzing the data,it is found that in the current chemistry unit review courses,the cultivation of students’ abilities are neglected,the subjectivity of students in class and the connection between class and life are ignored.Secondly,put forward the principles and implementation process of teaching design for life-oriented problem solving based on the deficiencies of the chemistry unit review class:raise life-oriented problems—analyze problems—solve problems—evaluate and summarize,and explain the ways of acquisition of life-oriented materials and strategies for raising issues of daily life at the stage of raising life-oriented problems,several different evaluation and summary methods are proposed in the evaluation and summary stage.Finally,the ninth grade chemistry textbooks published by the People’s Education Edition were screened and analyzed,and select units suitable for life-oriented problem-solving teaching models to provide a basis for the writing and implementation of the case.Part Ⅳ:Teaching design and practice of chemistry unit review course.Based on the teaching design principles and implementation process of life-oriented problem-solving teaching,choose three units suitable for life-oriented problem-solving teaching,which are Case 1:”Fuel and Its Utilization";Case 2:"Metal and Metal Materials";Case 3:”Solution",and according to the main line of teaching,the knowledge points of this unit are transformed into multiple life-oriented problems to carry out the unit review lesson teaching design,and case 1 and case 2 are practiced in middle schools.Part Ⅴ:Analysis of practical results.After practicing the case,conduct a questionnaire survey and student interviews and teacher interviews to gather the practical data and materials,and analyze the results respectively.Part Ⅵ:Conclusions and prospects.By analyzing results of the case practice,conclusions are drawn,and the deficiencies are reflected,and the prospects for the research content of this paper are put forward.Research shows that it is feasible and effective to implement a chemistry unit review course with the theme of life-oriented problem solving,which can shorten the distance between the classroom and life,help to give full play to the subjectivity of students in class,improve students’ practical problem-solving ability,and help students to construct knowledge and realize to apply what they have learned.
