Research On Teaching Design Of High School Physics Unit Based On Task Driven

With the promulgation of the "General High School Physics Curriculum Standard(2017 Edition)",the unit teaching model that allows students to construct a knowledge system in an integrated,modular and systematic manner has gradually been recognized by educational experts and front-line teachers.However,in the actual teaching,it is found that the overall grasp of the content of a unit to guide the actual teaching has the disadvantage of lack of operability.This study applies the task-driven teaching mode to unit teaching,which makes the guiding significance of unit teaching more specific,easier to operate and implement.This paper first studies the “task-driven” teaching mode and “unit teaching”through literature review and integration,find that the two concepts have a high degree of compatibility.On this basis,this paper innovates the teaching mode.There are few research that combines task-driven teaching with unit teaching both at home and abroad.Through theoretical and practical research,this paper combines the advantages of task-driven teaching mode that can arouse students' enthusiasm for learn and the advantages of unit teaching mode that can cultivate students' integrity and coherence in knowledge.Later,through the questionnaire survey and interview,this paper investigate the the current situation of high school physics teaching and the feasibility of unit teaching based on task-driven,then positive conclusions were obtained.The unit teaching design model based on task-driven is constructed on the basis this.The task-driven teaching design of high school physics units should be designed based on several aspects such as curriculum standard analysis,textbook analysis,and student learning situation analysis.In this way,teaching can not only be student-centered but also give consideration to the integrity and system of the knowledge.In order to make the teaching objectives generated in the unit teaching,the specific procedure of unit design was given in this study:(1)to establish the unit theme and analyze the unit objectives;(2)to design the unit tasks based on the unit objectives;(3)to design the classroom tasks based on the unit tasks;(4)to reflect and evaluate the tasks.The lesson "The Relationship between Motion and Force" is used as an example to design the unit and carry out it in practical teaching.The effect of this teaching model was analyzed by means of student performance evaluation and academic performance analysis.Through teaching practice,it can be seen that the task-driven model does add vitality to practical teaching.From the perspective of classroom performance,the greatest role of the task-driven unit teaching is to pull students who have lost interest and confidence physics back to the physics classroom.Judging from the results before and after the test,the experimental class has made significant progress compared with the control class.Therefore,generally speaking,the adoption of task-driven unit teaching has an obvious effect on promoting teaching.
