Teaching Design Of High School Physics Unit Based On UbD Mode

As a basic education curriculum,high school physics curriculum lays emphasis on cultivating students’ core quality of physics and building an integrated teaching system of "teaching,learning and evaluation".Based on the above background,some domestic scholars began to introduce UbD model for unit reverse teaching design,and carried out practice and research.It is known from relevant literature that unit instructional design is not only an effective way to achieve the goal of subject core literacy,but also a good opportunity for teachers to research subject core literacy and students to construct the concept of subject.And the unit reverse teaching design based on UbD mode can assist in the construction of "teaching-learning-evaluation" integrated teaching system.Based on the UbD model,this paper carries out the unit reverse teaching design in pursuit of understanding for the Conservation of mechanical Energy.It follows the design principle of "ending as the beginning",starts from the long-term expected learning results,designs the classroom according to the feedback from all aspects,and integrates the idea of "teaching,learning and evaluation" integrated teaching system.By enabling students to actively construct meaning to master subject knowledge and skills,exercise scientific thinking and cultivate scientific inquiry ability,so as to implement the cultivation of core physical literacy.The main research contents of this paper are as follows:First of all,the requirements for basic education curriculum put forward by Physics Curriculum Standards for Senior High School(2017 Edition,2020 revision)are described,and the development status of UbD theory at home and abroad is reviewed in detail,and the theoretical basis of UbD model is briefly described.The concepts of physical core literacy,UbD reverse instructional design and unit instructional design are defined.Secondly,By means of questionnaire,this paper carries out data statistics and analysis on the teaching design status of high school physics teachers,it is found that there are two main problems in high school physics teaching design at present: some teachers think that teaching design is not oriented to teaching objectives;Some teachers ignore the evaluation based on students’ learning perspective.By means of questionnaire,the actual situation of physics teaching design in middle school is analyzed statistically.Then the teaching strategy is applied to UbD model reasonably,and discusses the construction process of three aspects of reverse teaching design from the perspective of unit teaching.Finally,taking the Law of Conservation of Mechanical Energy as an example,it shows that students’ expected learning results are defined in the first stage,appropriate assessment tools are selected in the second stage,and unit reverse instructional design related to the teaching process is planned in the third stage.In addition,front-line teachers are interviewed on UbD design cases,and reflection and summary are made in combination with previous studies.In the reverse unit teaching design of Conservation Law of Mechanical Energy presented in this paper,metacognitive teaching strategy is applied to provide suggestions for teachers to design the reverse unit teaching design,and make contributions to updating the concept of educational evaluation and implementing the goal of core physical literacy.
