| In 2017,the country formulated a new high school curriculum standard,stipulating that the cultivation of students’ core literacy is the main teaching goal of each subject.In the core literacy system of high school disciplines,physics also has four core literacy including scientific thinking.The first requirement of scientific thinking literacy is model construction.In-depth study of effective modeling teaching strategies can help students learn physics better and understand the world more scientifically,which has practical significance.This topic is mainly researched through literature analysis,interviews,questionnaire surveys,case practice analysis and other methods.The main content has the following five parts:The first part is to analyze the literature to understand the research status at home and abroad,and to determine the research process and deficiencies of the subject.Starting from the needs of society and the actual teaching situation of high school physics,the purpose and significance of the research are explained,and the research content and research methods are determined.The second part analyzes the characteristics of modeling objects and divides high school physical models into four categories: physical models,state models,process models and system models,and sorts out the physical models that appear in the high school mechanics part.Combining pedagogy and psychology theories,analyze thinking skills related to modeling ability training,and lay a theoretical foundation.The third part,through two forms of student interviews and teacher questionnaires,it is understood that there are two forms of high school physics teaching: teachers and students have insufficient understanding of core concepts such as physical models,students’ modeling ability is lower than normal,and there is a lack of practical and useful modeling ability improvement strategies.Wait for the situation.The fourth part is to design strategies to improve modeling ability,which mainly discusses the improvement of physical modeling ability from two aspects of teacher teaching and student learning.Teachers’ teaching strategies mainly include: preparing a modeling teaching plan in advance according to semesters,chapters,and festivals;teaching analogies based on physical models and using information technology;integrating process models into the history of physics,creating actual scenarios,“explicit questions”,drawing Modeling mind map;improve system awareness and appropriately select the overall method and the isolation method for the system model.Aiming at the three links of pre-class preview,class learning,and after-class exercises,students’ learning strategies to improve modeling ability are proposed.In the fifth part,two cases of mass point and flat throwing motion laws are set up according to the modeling strategy,teaching practice is carried out,and the practical significance of related strategies is analyzed.The research results of this topic show that: strengthening teachers and students’ understanding of core concepts and adopting strategies from both teacher teaching and student learning are conducive to improving students’ modeling ability and helping students to better learn physics... |
