Course Case Analysis Of " Three Teaching Concept+ Problem Series" To Promote Mathematics Deep Learning Of Junior Middle School Students

Deep learning is a high-level thinking activity,which focuses on the internal connection of knowledge,emphasizes the application and integration of learned knowledge,and has the characteristics of understanding and criticism,connection and construction,transfer and application.In the actual learning process of students,teachers should cultivate students’ thinking ability,innovation ability and practical ability,which is the requirement of mathematics core accomplishment and curriculum development.The teacher should guide the student to understand the mathematics thought,master the mathematics method,grasp the mathematics essence.Combined with the relevant theories of deep learning,this study tries to explore effective ways to promote students’ deep learning of mathematics by starting from "three education" and "problem series".First,a questionnaire was prepared.Based on knowledge,communication and emotion,this paper investigated the current situation of mathematics deep learning among 260 junior middle school students in a district of Dalian.The results show that junior high school students have certain ability of deep learning,and the three areas of deep learning ability is more balanced;The ability of deep learning of junior middle school students needs to be improved,especially the ability of thinking,communication and reflection.The deep learning ability of junior middle school students improved with the increase of grade.There was no significant difference between grade two and grade three,but it improved significantly compared with grade one.Although the deep learning ability of middle school students is slightly better than that of boys,there is no significant gender difference.Secondly,the eighth grade students who are closest to the level of deep learning of junior high school students are selected as teaching objects,and the concept of primary function and isosceles triangle property are selected as teaching contents to form teaching cases for the analysis of class examples.Two teaching contents of the selected based on the concept of "three religions + string" teaching design,put it into teaching practice,around the embodiment of the concept of three religions,such as string analysis for deep reflection,and develop deep learning questionnaire of college students,to explore the problem of "three religions + string" on the depth of the junior high school students to learn.The results of the case study show that the teaching of "three education + question series" has a good promoting effect on the deep learning of junior middle school students.Finally,the enlightenment of this study to teachers’ teaching is summarized.The teaching process should cultivate students’ thinking ability and practical ability;Focus on cultivating students’ communication and teamwork skills.
