The Research Of Senior Chemistry Student's Grouping Experiment About Design And Practice Under The New Curriculum

Grouping Experiment Teaching is an important method in chemical experiment teaching.It is also an effective way to achieve the experimental teaching goal and improve student,s overall ability.In the Grouping Experiment Teaching,the students who are guided by the teacher,think and operate to explore the matter properties and chemical principles.There are many advantages,for example,is helps students grasp the chemical knowledge,stimulates students' interest in study chemistry,cultivates students' good thinking habits,and train their cooperative ability and team spirit.It,s obvious this form of teaching plays an important role.Therefore,it is very necessary to study the teaching situation,put forward the teaching strategies of it in high school,and apply the teaching strategies to teaching design to be tested in practice.The following works were done in this papers: Task 1: Deeply discuss the background of curriculum and significance of Grouping Experiment Teaching.Define the concept of Chemical Experiment,Teaching of Chemical Experiment and Grouping Experiment Teaching Method.The basis of teaching theory was analyzed to find out pedagogical implication.This papers analyzed teaching situation,teaching strategies and teaching design which studied by predecessors and put forward the approach and method of the research.Task 2: Grouping Experiment Teaching Method in Chong Yi county is investigated through questionnaires,which mainly includes the students' preference for the form of experiment,the students' mastery of experimental teaching,their attitude to the experiment teaching before,throughout and after the experiment,and their evaluation and expectation of the experiment.Task 3: According to the above investigation results,combined with experimental teaching theory,this paper puts forward some strategies to improve the teaching effect.Task 4:Based on the strategies,several types of chemistry experiment teaching methods were designed and practiced,and the effectiveness of teaching strategies were tested.Through the work of the four parts above,combined with the teaching practice,the following conclusions are obtained:(1)There are many problems about the form of experiment teaching,So,it is not optimistic of the effect in Chong Yi county in current times:(1)Students are strongly dependent on teachers.(2)Laboratory lessons are mainly teachers' tutorial while students just by “taking medicine” by imitating(3)The exploration of the experiment is poor.(4)Experiment grouping method is simple and limited(desk mate,neighbor mate).(2)According to teachers' ideas,Exploring teaching of experiment,experiment teaching grouping methods,teaching space exploration,evaluation of experiment teaching,three kinds of experimental teaching cases of students grouping experiment are designed,including the confirmatory penetration exploring,exploring penetration validation,fully exploring,which obtained significant teaching effect through teaching practice.
