Research On Performance Assessment Oriented By The Cultivation Of Physics Key Competence

How to cultivate students' core quality in physics is one of the hot issues in the field of education today.In the process of cultivating students' core literacy in physics,how to scientifically and effectively evaluate students' literacy development level is very important.Compared with a single paper-and-pencil test,performance evaluation can evaluate and supplement the literacy that can't be detected by paper-and-pencil test,and has the advantage of promoting the integration of teaching,learning,evaluation and truly realizing the "development of students' core literacy".Based on the cultivation of the core quality of physics,this paper studies the performance evaluation of physics,which is of theoretical and practical significance to the current curriculum reform and physics teaching in middle schools.The main achievements and innovations of this paper are as follows:1.The analytical framework of students' "physics learning performance" based on the core literacy of physics is put forward,which provides a theoretical basis for the formulation of physics performance evaluation tools.2.Designed a performance evaluation gauge based on the cultivation of core literacy of physics.The first step is to collect and sort out the existing physical performance evaluation gauges with reference by using the method of work analysis,so as to provide a realistic basis for the new gauge design.Step 2: Based on the quality standard of physics studies,deconstruct from the implicit dimension(core quality of physics)and the explicit dimension(performance of physics learning),establish a gauge framework,and depict the performance differential standard of core quality of physics.Step 3: Revise and improve students' performance indicators,and construct a physical expressive evaluation gauge which is applicable to different performance levels and has universal significance.3.Apply the designed physical performance evaluation gauge to the real physics classroom implementation evaluation.The analysis results show that: Teachers provide students with fewer opportunities for performance,and generally observe;Lack of students' scientific attitude and responsibility accomplishment;The students' expression style does not match the corresponding accomplishment training goal;The students' performance level is mainly up to standard,and the operational performance level needs to be improved.Students' performance shows "two-level differentiation" and their collective participation is not high;Some teachers did not give timely feedback to students' true performance.4.In view of the problems existing in the evaluation results,some suggestions on teaching optimization are put forward: Pay attention to the expression of students' scientific attitude and responsibility;To provide students with the expression suitable for their literacy goals;Strengthen the level of core literacy and cultivate awareness in an advanced way;Choose the evaluation gauge independently or adjust it according to the need.The purpose is to provide reference for physics teaching and evaluation in middle schools.
