The Application Of Using The "Task-oriented" Study Case In Teaching Metals And Their Compounds

Under the background of new curriculum,teachers need to update teaching ideas,change teaching methods,to improve the effectiveness of classroom teaching.In this paper,exploring the application of "task oriented" study case to high school chemistry teaching in the third chapter metals and their compounds to t improve the effectiveness of chemistry classroom teaching.The whole article is based on the "task-oriented" study case as the carrier to carry out the teaching process and the correlation strategy research in the third chapter of the compulsory course.In the course of specific research,this paper adopts experimental method to carry out teaching process in experimental class and control class.The experimental class adopts "task-oriented" teaching,And the control class adopts the traditional teaching,namely,teaching without study case.Finally,through a series of empirical studies,such as pre-test,post-test,interview analysis,and after-school tracking homework analysis to analyzes the positive significance of"task-oriented" study case in the teaching process.In the whole process of teaching implementation,the main role of students and the leading role of teachers are embodied in the application of "task-oriented" study case.This study consists of five parts:The first chapter mainly elaborated the background and origin of this study,research purpose and meaning,the present situation of the study,research method and content.The second chapter is theoretical basis of the study,introduces the meaning of learning case respectively,humanistic theory,constructivism learning theory,the theory of the zone of proximal development as the theoretical support of this paper.The third chapter is "the design of research",which mainly elaborates the object of the study and the design of "task-oriented "study case.The design of the testing tool for the formation of the section,the design of the test questions after class,the design of the interview and the design of the classroom observation.The fourth chapter is "the results of the study",mainly from the test,practice after class,students’ changes,interview these four aspects to analyze the results of by using"task oriented" study case in the teaching of in class(2)and by using conventional teaching in class(1)to form the results of the study.The fifth chapter is conclusion and prospect,this chapter mainly summarizes the theoretical achievements of this research and the teaching effect and it’s problems...
