Research On The Define And Application Of Physics Micro-teaching Evaluation Index

The physical micro-lesson is based on micro video as the main carrier,and aims at physics knowledge,contextualized network education resources.Today's social network teaching is highly developed,especially the new curriculum standards in the education reform under the guidance of middle school physics teaching,the physical micro-lesson as an auxiliary way to improve the efficiency of physics teaching has received the attention and recognition of many front-line teachers.Micro-lessons play an indispensable role in modern education and teaching as the assistant teaching resources.However,the quality of some micro-lessons is uneven at the present stage.It is indispensable to develop the definition of evaluation indexes for physical micro-lesson and the effect of its application.The essay uses the literature review method,the questionnaire survey method,the interview method,the case analysis method and the entropy weight method to implement the definition of the evaluation indexes and the effect of its application.The first chapter comprehensive network questionnaire survey and literature review analysis that micro-lesson has a good auxiliary effect in middle school physics teaching.The appropriate development and implement of micro-lesson can stimulate students' interest with study,and that will be very helpful to improve the quality of physics teaching;the second chapter defines the relevant concepts and theoretical basis of the research.The third chapter generalize the characteristics of physical micro-lesson based on the investigation of high-quality physical micro-lessons resources online.In addition,the essay classify and elaborate micro-lessons and physical experiments.The fourth chapter analyzes the relevant elements of the evaluation indexes of physical micro-lessons,and statistically obtains the first and second evaluation index scales of the physical micro-lesson.The entropy weight method was used to calculate the weight coefficients of the primary and secondary indicators of the appraisal scale.The reliability and validity of the appraisal scale were statistically analyzed using software SPSS 21.0.The fifth chapter is the application and analysis of physical micro-lessons.Firstly,it compares and analyzes case 1"overweight and weightlessness".Secondly,it analyzes and describe the case 2 "lost and recovered pieces of paper".It uses physical micro-teaching evaluation indicators to evaluate the missing paper of physical micro-lessons.Finally,it design and record 4 physical micro-lessons based on evaluation indicators of the physical micro-lesson.The micro-lesson study which been studied above is not only to enrich the resources of the physical micro-lesson but also can test the significance and practicality of the evaluation index of physical micro-courses.The sixth chapter is the conclusion and prospect which summarizes the related work of this essay and draw 4 constructive conclusions which can be used for reference to the first-line teaching in the actual physics teaching.
