Research On Core Ideas Of Electrostatic Field And Their Learning Progressions In High-school Physics

Learning progressions is mainly to focus on a few important concepts from shallow to deep curriculum organization,high school physical electrostatic field part is mainly to popularize basic electrical knowledge to students,teaching content to concept teaching mainly,because the invisibility of electrostatic field,based on static field related physical concepts for students is very abstract,difficult to understand Students are required to indirectly build a model of electrostatic field physics in their minds through the macro phenomena that appear outside the static space,as well as other physical knowledge.However,due to the macro-phenomenon and concept of electrostatic field is very different,it is difficult to establish a relationship,thus affecting the learning effect of electrostatic field.However,due to the macro-phenomenon and concept of electrostatic field is very different,it is difficult to establish a relationship,thus affecting the learning effect of electrostatic field.The concepts of the entire electrostatic field section are interrelated,and if there is a problem with the learning of a concept,it may affect the student's learning of the later concept.This undoubtedly requires teachers to pay more attention to the teaching of all students,understand the level of electrostatic field "step by step" teaching,grasp the rhythm of teaching.Learning progressions is actually the concrete process of the principle of "step by step" in teaching,which not only requires teachers to master the psychological knowledge such as the objective law of students' physical and mental development,but also sets a small stage goal for teaching.The completed advance arched the teacher's teaching mode for reference,which made the teacher's idea of teaching clearer and the goal more specific.Learning progressions is of great significance to teaching evaluation,and learning progressions research can promote the consistency of curriculum standards,teaching and evaluation,and learning progressions has a specific and easy-to-implement phase evaluation model for the final evaluation in educational evaluation.This paper hopes to elaborate the theoretical and practical significance of the study of the core concept of electrostatic field through the combing and screening of the electrostatic field content slot contents of the relevant literature,the standard of the physical curriculum of ordinary high school and the content of each version of the teaching material.Summarize the current research status of the core concept and learning progressions at home and abroad,retrieve and summarize the core concept of the physical electrostatic field part of our country's high school,and express the advanced level of the concept of high school physical electrostatic field.According to the advanced level of the core concept of high school physical electrostatic field,the teaching design is formulated to help the teaching practice of first-line teachers in the electrostatic field part.By comparing the three teaching materials,combing out the concept map of electrostatic field knowledge,and referring to the opinions of high school physics first-line teachers,this study determines the core concept of learning advance as " electrostatic field ",and according to the concept map to determine the primary advanced level,At the same time,according to the concept map to compare and analyze the important concepts in the electrostatic field corresponding to the degree of knowledge integration.With the first-line teachers to discuss,to adjust the advance of primary learning,to NanChang,Jiangxi Province,an ordinary high school 136 high school students as the research object,through analysis and screening exercises,home-made electrostatic field test volume as a learning progressions test scale,the adjusted electrostatic field learning advance to carry out quantitative research.First of all,through reliability analysis and validity analysis to determine the static field test volume suitable as a test scale,and then statistics test data accuracy and concentration,through detailed comparison and analysis of the statistical results of each problem group to determine the advanced level.Finally,based on the results of the study,five teaching strategies are put forward,and the shortcomings in the reflection study are summarized.
