Research On The Design Strategy Of High School Physics Unit Teaching Based On Learning Progression

The physics curriculum standards for ordinary high schools propose core competencies in the subject,which shifts the focus of teaching from teaching conclusions to cultivating thinking.However,due to changes in teaching objectives,there have been certain limitations in the current teaching design and teaching.Based on the above background,four questions are proposed: firstly,how to structure and systematize knowledge within units based on learning advancement? Secondly,how to design high school physics unit teaching based on learning advancement? Thirdly,what strategies are proposed for advanced learning based unit teaching design? Fourthly,how can high school physics classrooms effectively enhance students’ core literacy in the field of physics?The learning process is a progressive process that takes knowledge as the carrier and deepens scientific thinking step by step.The advancement of knowledge carries the advancement of thinking,with hierarchy and stages.Unit teaching design is a bridge between course development and class hour implementation,and unit teaching is the main way to enhance the core literacy of the subject.Integrating advanced learning and unit teaching design not only reflects each other’s advantages,but also has strong operability,which is an effective way to implement the core competencies of the discipline.Through consulting relevant literature and works,this paper analyzes the development status,confusion and shortcomings of the existing learning advancement and unit teaching design,and combines the theory of the nearest development zone,cognitive Development theory theory and constructivism theory,puts forward the preliminary strategy of high school physics unit teaching design based on learning advancement: situation problem strategy;Hierarchy development strategy;Correlation-overall strategy;Evaluation-Literacy Strategy.According to the preliminary strategy,the unit example of "Conservation of energy of Electric Energy" is designed and implemented.The effect of the implementation of the preliminary strategy is tested through classroom observation,teacher interviews,student homework feedback and other ways to provide a practical basis for improving the preliminary strategy.According to the specific implementation of the unit teaching design of "the Conservation of energy of electric energy" under the guidance of the preliminary strategy,the significant advantages of the unit teaching based on advanced learning compared with the conventional teaching are obtained,which further explains that the four strategies of the unit teaching design of high school physics based on advanced learning have certain value.Then,the preliminary strategy is improved and deepened according to the effect,and finally the corresponding application suggestions are put forward.
