Teaching And Practice Of Junior Middle School Physics Exercises Based On Core Literacy

Physics exercises teaching is an important means to improve students 'ability to analyze and solve problems,and to cultivate students' quality.At present,most of the domestic strategies for the study of exercise teaching are based on the purpose of examination-oriented education.The core literacy-based exercise teaching research is mostly in the high school stage,and the amount and depth of junior high school research are far less than that in high school.Moreover,in the existing literature,most of the teaching research on junior high school exercise classes is based on the core literacy goals of senior high school physics as a reference,and there is a certain gap between the teaching reference standards and students' academic situation.The junior high school physics textbooks and content,students 'physical and psychological characteristics,and students' cognitive characteristics are different from those of high school students.Therefore,there should also be corresponding differences in the mastery of various skills and the level of achievement of goals.In order to better integrate with the teaching practice,it is necessary to construct a junior high school textbook and learning without deviating from the four major themes of "physical concepts","scientific thinking","scientific inquiry" and "scientific attitude and responsibility".The specific element framework of junior middle school physics core literacy,and the effectiveness study of junior middle school physics exercise teaching under the guidance of this specific literacy goal,thereby making the task and direction of junior middle school physics exercise teaching more clear.The research ideas of this paper are as follows: First,by collecting and collating the literature,learn about the current research status of exercises based on core literacy at home and abroad,and draw on existing studies to clarify the research direction.Secondly,through the questionnaire survey and interviews to investigate the current situation of local junior middle school physics exercise teaching,analyze and summarize the existing problems.Then,find the theoretical support of teaching,combined with the local education and teaching conditions and teaching practices,and explore effective teaching strategies that are conducive to the implementation of core literacy in junior middle school physics exercises.Then,using "Planar Mirror Imaging" as the content,carry out heterogeneous teaching design in the same class,and compare and analyze the implementation of the literacy goals of the two teaching designs through a questionnaire.Whether the role played by aspects is real and effective.Finally,summarize the research results and reflect on the research process.The research focus of this article is to take the physics core literacy of junior high school as the goal,to explore teaching strategies that are conducive to the implementation of physics core literacy in exercise classrooms.Combining academic situation and education and teaching conditions,we have selected selected exercises,problem sets from shallow to deep,Optimizing teaching strategies for students with multiple questions,multiple teachers for one question,introduction of experiments,information technology,introduction of physics exercise teaching,and establishment of a learning community,giving full play to students' initiative in physics exercise classes in junior high school,allowing students to learn and lead Students experience the process of scientific inquiry and problem solving,cultivate students' scientific thinking,and further improve their comprehensive quality.Then,this article designs the teaching case of exercises based on the core literacy of junior high school physics.The four aspects of traditional physics are the determination of preset teaching goals,the selection and arrangement of exercises,the use of teaching strategies,and the implementation of literacy goals.A comparative analysis of the teaching design and effectiveness of exercise classes,and preliminary conclusions have been drawn that the physical exercise instructional design oriented to junior middle school physics has obvious advantages in the balanced realization of literacy goals,and provides a reference and experience for future teaching practice.
