Three Methods Of Teaching Under The Theory Of Constructivism In The Teaching Of High School Chemistry "Cell" Applied Research

The implementation of the new curriculum standard has exerted significant changes in terms of the intension and extension of chemistry courses.The changes not only bright about thinking concussion towards educational workers,but also new challenges for education practice.Traditional educational mode,namely teacher-oriented,does not apply to the requirements of new curriculum.Therefore,the teacher-oriented teaching mode must be altered and we should construct student-oriented newly teaching mode.This paper is going to research this newly mode theoretical fundament based on the teaching process of constructive theory.Currently,there exist three questions about the teaching process of chemistry courses.Firstly,the classroom teaching design lacks creativity.Secondly,the classroom teaching design lacks interestingness.Thirdly,the classroom teaching design lacks humanity.These are not conductive to the cultivation of talents with innovative mind of current social requirements.The first chapter is the introduction part.Firstly,it illustrates the importance,feasibility and urgency of Constructivism Theory in teaching design.The core of constructivism is "student-oriented".It emphasizes students’ active exploration and discovery of knowledge so as to improve students’ self learning ability and learning efficiency,and make the students become the main body of information receiving,understanding and processing.And through the consultation of literature,we introduce the status quo of constructive theory at home and abroad.In the second chapter,through consulting the related literature,this paper expounds the theoretical basis of the ideological origin,main points and the teaching methods of the three kinds of teaching modes.Three kinds of teaching methods,scaffolding instruction,anchored instruction and random access method are introduced in this paper.In the third chapter,the three kinds of teaching methods(scaffolding teaching methods,anchored instruction method and random access teaching method)are applied to pep elective fourth chapter the basic electrochemical ""electrolytic cell "lesson,teaching design respectively.And these contents are practiced in teaching segment.In the fourth chapter,through the analysis of the teaching effect in the classroom,teaching performance,interviews,surveys and other methods,Analyzing and comparing three kinds of teaching methods in the teaching process of "electrolytic cell" lesson.In the end,summarizing three kinds of teaching methods in high school chemistry teaching results and the existing deficiency in the process,and putting forward feasible suggestions.
