Teaching Research On Concept Of High School Physics Electromagnetism Based On Learning Progression

Learning progression has become a hot topic of education research rapidly in the world.It focuses on the process of continuous improvement of the thinking of students in learning core concepts.Meanwhile,the new curriculum standard emphasizes that teachers should pay attention to students' understanding of the learning content,different performance and relevant levels.Because of the abstract concept of "electromagnetism",it is difficult for high school students to learn electromagnetic knowledge.Therefore,this paper aims to help solve the problems of electromagnetism learning by studying the concept of electromagnetism.1.This article from the history of physics,the high school physics curriculum standards,senior high school physics teaching material,analysis of the concept of electromagnetism knowledge characteristics,constructing a concept map,with Camp software respectively to describe the electrostatic field ","circuit","magnetic field" and "electromagnetic induction" four core concepts and logical relationship between the small concept,getting the students' learning performance.Combined with the physical curriculum standards of junior high school and junior high school physics teaching material,to get the starting point of the concept of electromagnetism in high school,basing on the starting point,establishing the preliminary learning progression.2.For more comprehensive grasp of the student studies the electromagnetism concept learning performance,using BEMA and ECCE test optimization,forming test project,survey was conducted among 382 students of six schools,and uses the crash model to fit the data,combined with the thinking process of students,the electrostatic field respectively,The four levels of "electrostatic field","circuit","magnetic field",and"electromagnetic induction" are the levels of complete learning advanced levels.3.The two key points of the concept of electromagnetism that help students organize the scattered arrangement of the students are put forward.To connect the seemingly unrelated knowledge and inspire the students to imagine.Using camp software make the concept map of electromagnetism,the connection between the four core concepts under electromagnetism and progression of each concept were presented.Four core concepts related to the "power",select "power" theme,for example,the teaching advice,to achieve different levels of prestige,which puts forward the theme of teaching strategies as follows:?for connecting the levels of the transitional knowledge concept;? To integrate and prepare lessons with an important concept.? The interactive mode of teachers and students is carefully designed to explore the existing cognitive level of students.
