Research On The Application Of Guiding Case In High School Chemistry Teaching

Guiding Case guidance method is a teaching method that significantly improves the efficiency of chemistry classroom teaching in junior middle school and senior high school by fully reflecting the dominant status of students and giving full play to the guiding role of teachers.The use of Guiding Case for teaching,not only is in line with the concept of the new curriculum reform but also can fully demonstrate the quality of chemistry discipline.It is more suitable for the upcoming mobile course selection system as well as an effective way to improve classroom learning efficiency.Zhengzhou middle school is one of the sample schools of curriculum reform in Henan Province,which was demontrated in constantly exploring its own education and teaching mode.At this stage,Zhengzhou middle school adopts the teaching mode of Guiding Case teaching,which still needs to be improved in creation,application and implementation.In order to improve the current situation of daily teaching and cope with the upcoming implementation of the new college entrance examination,this research was carried out on the basis of the previous research and uesd the "constructivism" theory,"teaching students according to their aptitude" theory,"Recent Development Zone" theory,"Mastery Learning" theory and "teaching optimization" theory.This research was conducted using the methods of questionnaire,statistical analysis,literature research,observation and interview.And the following results were obtained.First,the specific problems in the current chemistry course guidance plan mainly include: students' lack of fun in cooperative learning,the capacity,the number of questions,and difficulty level in the design of the Guiding Case.Second,suggestions were put forward to overcome the existing problems.The relationship between the Guiding Case and the classroom teaching should be carefully dealt with before designing the Guiding Case in order to achieve the purpose of reducing the burden.The knowledge points of the Guiding Case correspond with question types,preferably those frequently tested so as to be familiar with the examination form of knowledge points in advance.Third,the coping strategies that suitable for the implementation of Zhengzhou middle school chemistry Guiding Case were summarized,including hierarchical design strategy,clear goal design strategy,problem driven strategy,cooperative exploration strategy and knowledge point exercise problem correspondence strategy.Fourth,the empirical research on the teaching of high school chemistry guidance plan was carried out in Zhengzhou middle school and the Guiding Case corresponding with classroom teaching content for different course types was redesigned.Positive feedback was collected when it was put into practice.In this study,a new Guiding Case was designed after explored the the application strategy of Guiding Case suitable for the current situation of high school chemistry teaching.The application of the Guiding Case for teaching and reflection was dedicated to strive to remedy the deficiencies and defects of the learning guidance model of Guiding Case chemistry teaching and lay the foundation for better implementation of shift teaching and reform of college entrance examination.
