Research On Construction Of Evaluation Index System Of Geography Micro-lesson In Middle School

With the convergence of information technology and education,as one of the applications of educationaltechnology,the micro class has caught extensive attention.In thedevelopment of geography micro class,its evaluation is the key link.At present,the evaluation researches of micro class lack of classified evaluation systems, this paper attempts to promote the development of micro geography classthrough the establishment of evaluationsystem.On the basis of the previous research,collecting 12 evaluation systems by literature research,selecting the indexes which were mentioned moretimes,exploring the essence of the micro class,the paper draws out anpreliminary evaluation index system of geography micro-lessons in middle school.Then,the paper investigates the backbone of excellent geography teachers who are the members of the national training program which is hosted by Inner Mongolia Normal University and the participants and winners for the third China Micro-class Competition. The paper finally determines the confirmed evaluation system by using rank and operation method.The evaluation index system of geography micro-lessons in middle school finalized by fiveparts,they are evaluation items,evaluation criteria,weight,composition and reviews rank.Evaluation system comprises two primary indicators, namely educational courses for the micro course and micro-class availability.Secondary indicators corresponding to the educational courses are:topics,teaching arrangements,activity design and teaching effectiveness;secondary indicators corresponding to micro-class availability are:completeness,standardization,diversity,technical quality and artistic quality.There are 24 evaluation criterias corresponding to the secondary indicators.Rank being excellent(85-100), good(70-84), qualified(60-69) and failed(60 or less) four grades.After evaluating three geography lessons with the evaluation index system of middle school geography class,the final evaluation results are basically consistent with the third China Micro-class Competition’s results.The three geography lessons are:Verify the existence of the Coriolis Force,which has won the first prize inthe third China Micro-class Competition;Graphically depicts precipitation--the change and distribution of precipitation,which has won second prize in the third China Micro-class Competition;and The fantastic journeyof Small drops,which won nothing in the third China Micro-class Competition.The evaluation system has the following characteristics:it has focused on student-centered;it is designed for the geographymicro lessons; and,it has a strong operability.
