Research On The "Green" Assessment System Of Academic Level In Junior Middle School Biology

At present,the domestic academic assessment research lags behind curriculum reform,whose practice study is still in the exploratory stage.Mature research about “large-scale "Class-Selection System" academic assessment is very few.In addition,the evaluation content is limited to knowledge.Therefore,the main purpose of this study is establishing the "green" assessment system of academic level in junior middle school biology,by analyzing the relevant policy documents and "biology curriculum standards",and using the assessment system to carry out the evaluation work.The whole research consists of three parts:The first part is the establishment of "green" evaluation index system,by using Delphy Fa,analytic hierarchy process and other methods;The second part is formulation of the evaluation strategy through literature research,and the designation of the evaluation reference cases;The third part is carrying out the work of academic assessment of the Elective-Course-Class students in grade 2 from Ganzhou No.3 middle school,and making analysis of academic level,to make grade judgment and comments.The research results are mainly two:1.The "green" assessment system of academic level in junior middle school biology was established.This system,includes a evaluation index system,evaluation strategies and rating and comments.2.The evaluation work was carried out and academic levels were analyzed.The academic level analysis includes academic achievement and grade analysis,correlation analysis and gender differences among grades,difference analysis between elective courses and grade or control group.Conclusions are drew from the results:1.Assessment should be multidimensional.A single dimension evaluation is not enough to represent the students' comprehensive academic level.2.Evaluation practice still needs to pay attention to the evaluation of basic knowledge.The basic knowledge can largely reflect the students' comprehensive academic level.3.There is no significant difference in gender overall the indicators.4.The basic knowledge of the students in the elective class is significantly better than that of the average grade.5.It is helpful to improve the students' academic level through the development of the elective course of the comprehensive practical activity course or the research study course.Through the action research,this paper puts forward suggestions as follows in practical work of junior middle school biology academic evaluation:Pluralistic evaluation should be emphasized in academic assessment;Teaching of basic knowledge should be emphasized;We should payattention to the guidance of interest in students' study;We should encourage to develop the school-based elective course in junior middle school;Evaluation scheme should not be too simple,whose degree of differentiation should be moderately increased.
