After the implementation of double reduction in the compulsory education stage,new requirements are put forward for classroom teaching in primary and secondary schools.The construction of efficient classrooms is even more imperative after the implementation of double reduction.The key to efficient classroom teaching is to effectively break through the teaching emphasis.Difficulties,most of the construction of efficient classrooms is dominated by teachers,summarizing difficult points in actual work,and taking problems reflected in daily practice and exams as breakthroughs,but for the same topic,students logical thinking ability and processing ability are not the same.,to make breakthroughs in the thinking process of difficult problems from the perspective of students,is a rare thinking and research idea in the relevant discussion of classroom research.Electromagnetics is a branch of physics that studies the laws and applications of electromagnetic phenomena.Junior high school electromagnetism allows students to conduct preliminary studies on various physical phenomena in this part of electromagnetics,and clarifies the definitions,concepts and theories of various basics.Students who have spare capacity to study will lay a foundation for their studies in high school and higher,and also provide a common sense popularization for students who will not engage in related content in their careers in the future.In the whole junior high school stage,electromagnetism is also regarded as an abstract and difficult content by students.Compared with mechanics,heat and optics,etc.,relevant concepts and laws are summarized from the life experience of the educated and the analysis of daily life phenomena.In the electromagnetism part,the phenomena that cannot be directly observed are internalized into concepts and laws,the way of thinking and learning has been raised to a higher level,and it has become more abstract and boring,which will shape the students’ logical thinking and simple physical models.to a certain effect.This part of the content is relatively important in the senior high school entrance examination,with strong comprehensiveness and logic,and there are many places where difficult problems occur.The learning ability of educated people in the electromagnetic part varies greatly,and it is very likely to be established by physical thinking.Due to the difference,students’ thinking is not linear,and how to break through the difficult problem of nonlinear thinking is very challenging.Aiming at the difficult problems encountered by students at different levels in the process of establishing physical thinking,taking the Bazhou area where they teach as a reference,focusing on 526 junior high school students in the fourth grade of Korla No.Attribution analysis is carried out on the difficult problems in the learning of junior high school physics and electromagnetism.From the psychological development and way of thinking in the whole process of students’ learning,the situations in which the students encounter difficult problems in the process of learning new knowledge are divided into psychological learning.Difficulties,situational learning difficulties,knowledge-based learning difficulties,thinking-based learning difficulties,operational learning difficulties.According to different difficult problems,make attribution to the difficult problems in the physical electromagnetics part of junior high school,analyze and design the scale of difficult problems,suitable for junior high school students’ reading comprehension ability and comprehensive investigation,and the scale design is in line with students’ reading ability and thinking level,has a certain degree of investigation and inspiration,through the final results,as well as the questionnaire survey of students,interviews and interviews with teachers of the department,analyze the causes of the difficult problems in the electromagnetic part,and give corresponding teaching strategies according to different causes.Break through the causes of difficult problems in the learning process of the educated,help the educated to solve the difficult problem,promote the development of thinking,and improve the educated’s interest in physics learning.Learning provides new ideas.Help teachers to break through difficult problems in classroom teaching in a targeted manner,scientifically grasp students’ thinking methods,provide assistance to promote students’ thinking development,achieve a two-way win-win situation for teachers and students in efficient classrooms,and provide ideas for basic education research in Bazhou and method. |
