Research On The Teaching Strategy Of Hands-on Experiment In Junior High School Based On Physical Core Literacy

As the curriculum reform continues,teaching is not only the acquisition of knowledge,but also the improvement of ability.However,physics teaching has been difficult,students are not interested in not learning,and even there is a phenomenon of giving up physics in the case of choice.In 2017,the newly revised physics curriculum standard proposed the physics core literacy teaching concept,while the junior high school still uses the three-dimensional goal as the curriculum standard.How to connect the junior high school teaching objectives and change the status quo of junior high school students who are not interested in learning and difficult to learn Research interests,through the actual teaching and access to relevant literature,found that changing the status quo should proceed from the essence of physics,starting from the teacher's concept and starting from the actual change of teachers.Physics teaching is not difficult,it is necessary to start from the experiment and is a life-oriented experiment.Through the review of the literatures related to life-based experimental teaching at home and abroad and the study of the teacher's teaching video screen,the characteristics of the life experiment itself and its role in teaching are sorted out.Based on the constructivist learning theory,the cognitive theory and the ecological teaching theory,combined with the problems in the physics teaching and learning of junior high school students,the design principles of life-based experimental teaching are put forward: the principle of pertinence,the principle of simplicity,and the interest Principles,inquiry principles,basic instrument principles.The design strategy of junior high school life experiment teaching based on physical core literacy is discussed: infiltration physical core literacy strategy,problem guiding strategy,situational life strategy,cognition conflict strategy,method diversification strategy and method explicit strategy.Based on the proposed physical education core literacy-based junior high school life experiment teaching strategy,five teaching examples of junior high school and north school physics were designed and targeted evaluation.Finally,the author puts forward the basic strategy and case evaluation based on the physical core literacy junior middle school life-oriented experimental teaching,and extracts a feasible junior high school life-based experimental teaching strategy based on physical core literacy: highlighting the core literacy strategy,problem guiding strategy,situation The life strategy,the cognition conflict strategy,the method diversification strategy,and the method explicit strategy.The teaching suggestions for the application of these strategies are put forward: clarify the three-dimensional goals of the teaching content,infiltrate the core literacy of the physics,choose the appropriate life situation,choose the rational life experiment,adopt the appropriate problem guidance,and highlight the physical method of education.
