Junior Middle School Electromagnetic Review Class Instructional Design Oriented By "Problem" Research

Through practical teaching,it is found that in the review of electromagnetic in junior middle school,students should memorize the laws of physical concepts by rote and mechanically train the set of questions.Combining with the "Compulsory Education Physics Curriculum Standards(2011 Edition)" requirements should advocate students to bring questions with a targeted review,take the initiative to participate in them.For this reason,junior middle school electromagnetic review instructional design oriented by "problem" is chosen for research.The "problem"-oriented junior middle school electromagnetic review teaching design application literature method and action research method.Based on the theories of constructionist learning,meaningful learning,proximal development area and information processing learning,the principles of instructional design are determined:guiding principles,logical principles and interactive principles.Based on the theoretical basis and the principle of teaching design,the author puts forward the "question-oriented" review teaching design idea:Determining the teaching objectives based on the problem ? creating situations to introduce topics ? reviewing knowledge with problem-oriented ? applying knowledge to solve the problem.Based on this design idea,the teaching design and practice of "voltage resistance" unit review,"electricity and magnetism" unit review and "electricity" comprehensive review in junior middle school are carried out.Through the analysis of the effect of students' classroom performance and homework feedback,teachers' feedback and self-evaluation on the teaching implementation,the research shows that the teaching design principle of "problem-oriented" junior middle school electromagnetic review based on the theoretical basis conforms to the teaching design of this study,and the teaching design based on the design idea is reasonable.From the determination of teaching objectives,creation of situations,introduction of themes,problem-oriented implementation of review and guidance of students to solve problems,this paper puts forward some teaching suggestions for "problem-oriented" review of electromagnetic in junior middle school.
