Exploration And Research Of Problem Mapping Based On Life Situation In The Training Of Junior High School Students' Physical Modeling Ability

With the continuous progress of society and the rapid development of science,the demand for talents has also changed.The country needs talents to promote the development of the party and the country.In the new era,talents pay more attention to the combination of theory and technology and need to be able to apply theories in practice.Students start to systematically learn physics from junior high school.Although students at this stage have weak abstract thinking ability,they have strong curiosity and are willing to explore and accept novel things.Physical model is the connection point between theory and practice,and the construction of physical model requires the combination of a variety of thinking abilities.The 2017 edition of Physics Curriculum Standards for General High Schools clearly includes students' physical modeling ability in their academic quality level.Teachers cultivate students' preliminary physical modeling ability in junior high school,which will help students integrate into high school learning and life more quickly when they enter high school.Question teaching has a great influence on cultivating students' thinking ability and inquiring consciousness since ancient times.Classroom questions are an essential part of teaching.To some extent,they can attract students' attention,guide students to think and stimulate their curiosity.Through preliminary investigation of the first grade classroom questioning,coupled with ETA physical cognitive model and teaching content,students' cognitive level mapping,design classroom questioning and mapping to issue method of teaching design and teaching practice,based on the problems mapping method teaching in junior middle school students physical model building level of application,To explore the influence of question mapping on classroom problems in teaching design and teaching activities.The main content of this paper is divided into five parts.The first part combined with the "problem teaching method" and "physical modeling teaching" domestic and foreign related research,tells the reason of training junior high school students' physical model building ability,the impact of problem mapping and problem teaching method on the training of junior high school students' physical modeling ability and the current situation of problem teaching of junior high school students.The second part classifies and introduces the related theories of problem mapping,problem teaching and physical modeling ability,involving "cognitive assimilation learning theory","constructivist learning theory","ETA physical cognitive model" and so on.The third part is the design strategy of problem map based on life situation.It mainly introduces the choice strategy of problem situation and the design strategy of problem map."Lens and its application in the fourth part in view of the junior middle school physics" this part of content,design the four series of maps,namely the whole content of the problem of mapping,the problem of "lens" map,"lens" related problem sets the problem of mapping and the question of "the law of the convex lens imaging" mapping,to guide graph based problem,method of teaching design for related content problem.The fifth part is the educational practice part.Will be based on the problem of mapping method of teaching design is applied in the actual teaching,the teaching practice,according to the questionnaire and test data,discusses "lens and its application" questions in this section map to the teaching design and classroom questioning and the influence of the junior middle school students physical model building and so on,to find the first,students for problem situation can directly see,More impressive.Secondly,the overall logic of classroom questions based on the problem mapping design is strong,which can clearly show the relevance between knowledge points.Third,classroom questions designed according to the question map can improve students' ability to distinguish opinions from evidence.
