Study On Application Of Portfolio Assessment In Chemistry Learning In Rural High Schools

At present,our country is developing rapidly with the rapid progress of science and technology.In order to maintain the rapid development of our country and promote more rapid development of science and technology,education reform must be emphasized.Education has a great responsibility to develop talents.In order to adapt to the development of the new era,basic education curriculum reform has been constantly explored.It is expected to promote the comprehensive,independent and individual development of all students.The new curriculum reform emphasizes the diagnostic and development functions of education evaluation,attention should be paid to other forms of evaluation other than traditional evaluation method.Portfolio evaluation is one of the diversified evaluation methods.However,it is still not valued in the teaching of rural high schools.Therefore,this paper puts forward the theoretical framework of rural high school portfolio evaluation on the basis of the existing literature,and explore the implementation methods and approaches,and demonstrate the implementation effect.It is expected to put forward a feasible strategy for the application of portfolio evaluation in rural high schools.The main problems of this paper are as follows:1.how to determine the connotation of related concepts of learning portfolio evaluation.2.how is the research progress about the learning portfolio evaluation at home and abroad.3.whether is it feasible to carry out portfolio evaluation in rural high schools.4.how to implement portfolio evaluation in daily teaching of rural high schools.5.what are the problems in the current implementation of portfolio evaluation and how to solve them.This paper is composed of five parts.The first part is the introduction,which explains the research background,research status at home and abroad,research content and significance,research methods and ideas.The second part is the theoretical basis,including the connotation definition,characteristics,principles and relevant theories of the portfolio evaluation.The third part is the preparation work before the practice,including the preparation of the questionnaire for the survey,the analysis of the results of the comparison class and the experimental class,the preparation of the interview outline and the determination of the portfolio evaluation system.The fourth part is practice research and result analysis,implementation of the study file cover evaluation including classroom learning evaluation,weekly summary evaluation,personality works collection and appraisal and the collection of the examination results and reflection,through the questionnaire and use SPSS software to analyze date.The fifth part is the conclusion and reflection and outlook,draw the conclusion and reflect on the shortcomings in the process of implementing chemical portfolio assessment in rural high schools,and put forward the development trend of portfolio assessment.Draw the following conclusions:(1)Portfolio evaluation in rural high schools should be based on teachers'consulting a large number of documents.The teacher should formulate the evaluation objective,the evaluation standard and the evaluation content in advance,and then negotiates with the students,finally determines the specific model of Portfolio evaluation.(2)In the progress of implementing portfolio evaluation in rural high schools,the teacher should give students timely feedback on the evaluation results,and act accordingly,such as talk to students or adjust teaching schedule.In this way,the portfolio evaluation can play its maximum effect.(3)The students' academic performance has been improved to a certain after the implementation of the Portfolio evaluation.Portfolio evaluation in rural high schools improves students' enthusiasm in learning chemistry.Portfolio evaluation has changed students' attitude towards chemistry study,it is effectively improve the enthusiasm of students.The students' chemical thinking ability has been improved.Portfolio evaluation strengthens the communication between teachers and students and between students and students,it makes the relationship between teachers and students?students and students become more harmonious.This paper puts forward the theoretical framework of the portfolio evaluation in rural high schools as the daily evaluation,and conducts practical research.It has specific implementation plans and processes.This paper hopes to provide some references for the portfolio assessment in rural high schools.
