The Design Of Physics Guidance Case For Efficient Classroom In Junior Middle School

With the development of the times,the national basic education is also constantly making adjustments.In order to achieve all-round teaching reform,teachers and researchers put forward a variety of teaching models for efficient classroom,among which the guidance case model is favored by many schools.The guidance case not only develops students' scientific inquiry skills,but also effectively enhances their scientific inquiry literacy.This study hopes to propose an effective method for the design of physics guidance case under the background of efficient classroom teaching,and this method is suitable for the actual teaching environment of the author's school.The author has referred to the domestic and foreign research results about the guiding case,and then determined the research route and method of this paper,this paper adopts many methods such as literature research,interview,comparison and investigation.Through those methods,this paper summarizes the research definition and characteristics of physics guidance case,and clarifies the main work of teachers need to do in the efficient classroom.In order to make the guidance case more suitable for the actual teaching environment,this paper studies the problems existing in the current junior middle school physics teaching,and makes independent investigation on the students and teachers,summarize the main problems in the design and use of the guidance case.Finally,the principles of the design are as follows:(1)The principle of subjectivity,making clear that students are the main body of the classroom and learning;(2)The guiding principle,guiding the direction of students,guiding students to learn independently;(3)The principle of class hours,highlighting the learning objectives of each class;(4)The situational principle,learning problems should be properly designed so that students can have cognitive conflicts;(5)The hierarchical principle,the learning guidance plan should be consistent with students' cognitive level,and the difficulty should be graded;(6)The real-time principle,the learning guidance plan should be updated according to the changesof student characteristics and times;(7)The open principle,the suggestions of students and teachers should be integrated.This paper further combines with the actual teaching environment,and makes clear the matters that need to be paid attention to the design of guidance case:(1)Identify learning objectives.Learning objectives need to be described from the perspective of students and according to the curriculum standards;(2)Write assessment tasks corresponding to learning objectives.Both design task evaluation and learning objectives should correspond to each other;(3)Provide learning guidance,including describing the importance of chapters and the relationship between chapters;(4)The design of learning process should not be separated from the teaching materials,so that students can experience the process of inquiry;(5)Set up necessary reflection after learning;(6)Cultivate students' scientific literacy,expand their horizons and arouse their interest.Finally,through the interview and evaluation of teachers and students,this paper shows the performance comparison after the implementation of the guidance case,and effectively evaluates the design effect of the guidance case.
