Application Of Expressive Evaluation Based On Learning Progression In High School Physics Teaching

The high school physics curriculum aims to implement the fundamental task of Lide Tree,and the core literacy of the discipline is the concentrated embodiment of the value of the discipline,so the cultivation of the core literacy of the physics department should run through the whole process of physics teaching activities.Among them,evaluation is an important part of daily teaching activities.The High School Physics Learning Assessment is based on the evaluation of the core literacy of the Physics subject,and its purpose is to promote student learning and improve teacher teaching.Therefore,in the context of the new curriculum reform,it is necessary not only to promote the transformation of teaching and learning methods,but also to promote the reform of the evaluation system.The 2017 edition of the curriculum standard clearly points out that the evaluation of high school physics learning should focus on the specific requirements of the core literacy of the physics subject,create a real and valuable problem situation,and adopt the evaluation method of multiple subjects and methods to objectively and comprehensively understand the development of the core literacy of the physics subject of students.The expressive evaluation emphasizes that students can complete more complex performance tasks in the most realistic situation as possible,and use the scoring rules to evaluate the process performance and final results of students completing performance tasks,so as to provide effective feedback for teachers' teaching and students' learning,so as to promote the development of students' core physics literacy and improve teaching.Therefore,in the context of emphasizing the evaluation of students' core literacy in disciplines,the traditional objective paper-and-pencil tests that only focus on basic knowledge and basic skills can no longer meet the requirements of modern educational evaluation,which requires us to go beyond the traditional evaluation methods and choose expressive evaluations that can evaluate students' "complex thinking and high-level cognitive abilities".Learning advanced theory requires evaluators to grasp the progress trajectory of students as a whole,divide students' ability levels from low to high into different grades,provide students with the necessary scaffolding,let students deepen complex thinking and advance towards higher-order cognitive abilities in turn when learning and exploring a certain topic,which coincides with the expressive evaluation concept that can evaluate complex thinking and high-order cognitive ability,so giving full play to the role of learning advanced in expressive evaluation is an important direction of current education reform.Therefore,teachers should give full play to the role of expressive evaluation based on learning progress in teaching,so as to achieve the purpose of "promoting teaching with evaluation and promoting learning with teaching".Investigating the application status of expressive evaluation in high school physics teaching,designing performance evaluation cases based on learning progress,and applying cases to practical teaching are the core tasks of this paper,which are mainly reflected in the following three aspects:First,through the questionnaire to understand the application of expressive evaluation in high school physics teaching,it was found that most teachers have a general understanding of expressive evaluation,and there are doubts about how to design and implement expressive evaluation and how to determine the scoring rules,so front-line teachers expect to provide reference for relevant teaching practice cases.Second,drawing on the existing literature,the expressive evaluation framework and implementation process based on learning progress are constructed,and the physics ability level divided by Guo Yuying's team is used as a grade model of "performance evaluation based on learning progress",and then the expressive evaluation teaching case based on learning progress is designed according to the evaluation framework,implementation process and grade model.Third,put the designed case into practice and analyze the practical effect.In the process of practice,two parallel classes are selected as control classes and experimental classes,and expressive evaluation is applied in the teaching of experimental classes,while the control classes adopt conventional teaching methods.The results show that the application of performance evaluation based on learning progression in high school physics teaching can improve students' interest in learning physics and physical achievement.
