| In the Opinions of the State Council on Deepening the Reform of Education and Teaching and Improving the Quality of Comprehensive Education of 2019,it clearly puts forward higher requirements for improving the evaluation methods.Under this kind of education idea,it is necessary to actively explore new evaluation methods that can comprehensively evaluate the development of students,and finally establish an evaluation system that can promote the all-round development of students.Under the background of "Internet +",it is a good way to use electronic portfolio in teaching evaluation.Through the literature investigation,it is found that there are many researches on the development of electronic portfolio.However,there are few study cases about the application of electronic portfolio in the evaluation of biology teaching in middle school.As a result,it carries out the research on how to make better use of electronic portfolio for teaching evaluation and how to use its effect as the research object.In this study,the application of electronic portfolio assessment in junior high school biology teaching was studied by literature research,questionnaire survey and experiment:(1)Middle school biology teachers have a good understanding of E-portfolio evaluation and a high degree of recognition for it.They believe that e-portfolio evaluation is helpful to improve students' learning interest,achievement,sense of participation and autonomy.However,due to the lack of research on e-portfolio evaluation and the lack of specific operational methods and teaching strategies,there are obstacles in the use of E-portfolio evaluation;(2)According to the related functions of Aixue platform,this paper summarizes the characteristics of E-portfolio evaluation based on this platform,such as convenience,growth,diversity,reflection,etc.based on the characteristics and principles of E-portfolio evaluation,the use strategy of E-portfolio evaluation is designed.(3)Through the experimental research,it is found that the application of E-portfolio evaluation has indeed improved students' biological learning performance,and students' interest and enthusiasm in biological learning have also been improvedto a certain extent.It has an obvious role in promoting their independent learning ability,cooperative exploration ability and the cultivation of innovative spirit,and has seen the overall development of students in the whole practice process.Through the summary and analysis of the above research,it is considered that the e-portfolio evaluation based on the love learning platform is feasible,which optimizes the three processes of collecting information,processing information and feedback information,effectively improves the teaching efficiency,better realizes the value of E-portfolio evaluation,and is conducive to promoting the overall development of students and realizing the timeliness and efficiency of evaluation. |
