The Development And Application Of "Pre-class Exercise Notes" For Junior School Chemistry

Under the background of that new curriculum reform advocates students? independent study,many researchers and practitioners have tried using “Pre-class exercise” text and changed the emphasis of education from teaching by teachers to studying by students.But then a problem emerged,which is that note-taking of students weakened.Superficially,students do not take notes,which is a kind of lack of learning processes and experiences in fact,namely,“students do not encode and store knowledge they learn in the process”.“Pre-class exercise” is the key of pre-class exercise education,so I integrate the effect of “Pre-class exercise” and the function of note to try and study “exploit junior chemistry ?Pre-class exercise notes? and apply it in education”.In the research of this article,I mainly use action research method,and use documentary method,case analysis method,text analysis method and questionnaire method in the meantime.I mainly consult the four steps(problem,plan,action,rethink)of action research.First,I found the problem,which is that n ote-taking of students weakened when using “Pre-class exercise”.Second,I consulted literature to master the research status of “Pre-class exercise”,“note”,“note and Pre-class exercise”.On this basis,I exploited junior chemistry “Pre-class exercise notes” and researched the development idea,compilation principle,framework,content and stimuli-presenting mode of junior chemistry “Pre-class exercise notes”.Third,implementing teaching in the experimental class,I researched the guidance countermeasures of teachers and the learning processes,results and feedbacks of students by teaching cases of teaching activities by teachers and students before,in,and after class.In the end,through “students? test scores”,“text analyses of notes”,“questionnaires about learning interests and the ways of taking notes ” and “individual interviews of students” and so on,the application results of junior chemistry “Pre-class exercise notes” were examined.In the same time,new problems were found and suggestions about follow-up study were put forward.Through this research,the following conclusions can be drawn:1.“Pre-class exercise notes” has a guidance of learning and potential function of notes.“The guidance of learning” of “Pre-class exercise” means students can feel the guidance of teachers about learning when they use it.The potential function of “notes” means students can receive teachers? intervention in note-taking methods when they use it,which makes students? thoughts appear and store better.2.The application of “Pre-class exercise notes” in the teaching has great results in “changing the teachers' ideas to ?students first?”,“improving students? scores”,“arousing students? interest”,“promoting students' notes to ?individuality expression?,“thoughts appearance” and so on.In a word,making and using“Pre-class exercise notes”in middle school chemistry is worth promoting.Because it reflects “learning decides teaching,teaching guides learning and evaluating promotes learning”.
