The Determination Of Teaching Important Points And Teaching Difficult Points Of Middle School Physics Based On The Core Literacy

Since the curriculum reform,teaching goal of physics course,from the original "double-base" becomes to "knowledge and skills","process and method","emotional attitude values",and then from "knowledge and skills","process and methodf","emotional attitude values" becomes to"physical core literacy"that consist of the physical concept,scientific thinking,scientific inquiry,scientific attitude and responsibility in 2017.The physical core accomplishment is the sublimation of the three-dimensional goal.physics teachers should pay attention to each link are embodied in the cultivation of student's physical core literacy when designing the teaching,this paper mainly studies on how physics teaching key and difficult are determined basing on the physical core literacy,and when determining key points and difficulties of the physical concept class,regular class,LABS and recitation teaching how to reflect to the cultivation of students' physical core accomplishment,research shows:(1)In determining the key points of each section in the middle school physics textbook,it is necessary to combine the three aspects of the content requirements of the physical curriculum standards,teaching material and physical core literacy."Physical curriculum standards" have the content requirements of each chapter,the level of knowledge requirement for each point is different;Teaching materials as a carrier,explain and introduce the contents of the "physical curriculum standards",the content of the different levels is explained with the different level;physical core literacy plays the role of teaching objectives,to determine the focus of teaching should pay attention to Cultivate students' core literacy skills(2)In determining the difficulty of each teaching in middle school physics teaching materials,teacher in addition to consider the above three aspects,but also consider the students,the cognitive structure of students,the formation of a long time thinking and existing knowledge reserve,which will have an impact to determine the teaching difficulties.(3)When teachers write the teaching design of physical concept course,regular course,experimental course and exercise class,they should reflect the characteristics of each course type,according to the methods of determining the focus and difficulty to determine the teaching focus and difficult,and paying attention to cultivate the students' physical core literacy.The focus of teaching is the key to a lesson,the key point is accurate,the teacher in the class is clear,the organization is clear.Students will grasp the key,clear mind,the effect is obvious.Difficulties has a catalytic role to understand the focus of teaching for student,so to determine the teaching focus and teaching difficulties is very important.This study provides the theoretical basis for the first-line teachers to determine the teaching key points and difficulties,and enriches the teaching theory results.
