Study On Optimal Design And Effective Use Of Guidance Case Of Senior High Physics

With the changes of the times and the development of the society,more and more innovative talents with knowledge and ability are needed in the country.Education is the foundation of developing our country for cultivating more talents who can make contribution to the national development,the reform of basic education in China is continuing.Under this background,the "Guidance case" becomes an outstanding mode in teaching.Under this mode,the students can study by themselves and the teachers only guide the students in proper time.It also highlights the student-oriented concept of the new curriculum reform and it plays an important role in building a bridge between teachers and students.Therefore,if the "Guidance case" could achieve it superiority,the optimal design and effective use become the key parts.At present,there are still many problems in the design of guidance case of senior high physics,such as the never changing of teaching plan,exercises and formalization.Many other problems are affecting the later design such as the students often copy the contents from textbook,the teachers` delaying of checking homework.These problems also widen the gap between the effectiveness and the goal of guidance case.On the basis of cognitive learning theory,constructivist learning theory and the zone of proximal development theory,the paper aims at putting forward some strategies and put them into the practice so that they can optimize the design and effective use of the guidance case.And the strategy of optimized design are the followings:(1)clear the teaching content and teaching goal,adjust the relationship between teaching materials and teaching cases;(2)highlight the variety of the presented contents(3)pay attention to the progressive learning and coexist the gradient and hierarchical(4)set up problems with pertinence and novelty(5)review the knowledge and make the knowledge in series.The strategies for effective use are:(1)draw the attention of students;(2)make the timely examination and correction;(3)use strategies not only in class but before and after the class(4)cycle the rethinking and summary.And the guidance case uses the interviewing and performance analysis in exploring,which refers to the evaluation and suggestions from the teachers and students to the optimized design of the guidance case.Taking a semester as a unit,the guidance case analyses the students`change of the physical results.Good results have been achieved.As a new teaching mode and has the bright future,the guidance case is born with the reform of basic education but it also needs to be verified in a lot of practice.Better teaching results have been obtained.The paper studies the design and use of the guidance case and make the study into teaching practice.The research results in this paper have some demonstrative and referential value for the practical teaching of middle school physics.
