The Study Of The Application About Performance Assessment In The Activities Of "Integration And Practice" In Junior Middle School

With the further development of the curriculum reform,the mathematics curriculum standards for compulsory education issued in 2011 puts forward new requirements on "Integration and Practice",enabling students to experience mathematical activities,accumulating certain experience in activities and cultivating students' mathematical literacy,which is enough to see the importance of activities.However,the existing educational research shows that the teaching evaluation mechanism of this part is still not perfect.How to make scientific evaluation not only bring into play the important function of evaluation but also promote the effective implementation of the activity has become a direct problem in the development of "Integration and Practice".In this study,60 mathematics teachers in the urban and rural areas of Yantai city were selected as the research object based on the "Integration and Practice" of junior middle school mathematics,and the influencing factors and evaluation status of the current implementation of the activities were analyzed through questionnaire survey and interview.Through the investigation,it is found that although teachers have a high degree of recognition,the number of projects implemented is very small,and there are four main limitations: the proportion of activity projects in the exam is small;Lack of resources for lesson preparation,activity topic is not easy to observe;Teachers' ideas are not valued;There is no clear method of evaluation.The deficiencies in evaluation mainly include: unclear evaluation standard,single evaluation subject,lack of evaluation function,and not paying attention to mathematical non-cognitive factors.An efficient evaluation method,Performance Assessment,is selected for the deficiency.This is a new evaluation method,which requires students to complete tasks in real or simulated situations.The teacher evaluates the classroom behavior performance according to certain standards,and explains that it has a strong match with the activity.Therefore,based on the successful evaluation experience at home and abroad,this study designed a set of standards-based performance evaluation steps to be applicable to the "Integration and Practice" activities in China.Finally,two types of activity design performance evaluation is selected as an auxiliary explanation,which isexpected to be a reference for teachers.Based on the implementation of Performance Assessment in "Integration and Practice",the following conclusions are drawn: Performance Assessment is the evaluation method matching with the "Integration and Practice" activity of junior middle school mathematics.The goal decomposition technique is used to refine the curriculum standard to determine the performance goal and to play the guiding role of evaluation.The application of performance evaluation makes the evaluation subject pay attention to the students and the group,and the evaluation subject develops towards the direction of diversification.The process of reverse design allows students to know the direction of efforts,where they are and how much effort they need to make,giving them a clear feedback.The evaluation also pays more attention to the students' interest and verbal expression in the process of activities and other mathematical non-cognitive factors.
