The Development Of The Evaluation System Of Physics Micro-lecture

With the development of educational informatization,micro-lectures are playing more and more roles in the teaching of various subjects in secondary schools.Micro-lectures have also been widely used in the teaching of physics in secondary schools.In the meanwhile,massive micro-lecture resources have appeared on the Internet.However,the quality of these resources is uneven,and there is no scientific evaluation system for them.Therefore,this study will address physics micro-lecture for secondary school and develop a scientific evaluation system about physics micro-lecture to solve these problems.This research includes the following tasks:1.Using the literature method,survey method and interview method to establish the drafts index of secondry school physics micro-lecture evaluation system;2.Using the Delphi method(expert opinion survey method)to establish the index of the evaluation system about secondry school physics micro-lecture;3.Analytic Hierarchy Process(AHP)combined with Delphi Method to determine the weight of each index in the evaluation system about secondry school physics micro-lecture,and finally establish the entire evaluation system about physics micro-lecture;4.Through twice of the actual tests of the evaluation system secondry school physics micro-lecture,the quality evaluation of the evaluation system was performed.Through the above works,the evaluation system about secondry school physics micro-lecture established in this study includes 3 first-level indexes,8 second-level indexes,and 19 third-level indexes.Through two tests,it is concluded that the evaluation system about physics micro-lecture has a high degree of reliability and validity,and is a good quality evaluation system.
