Research On Experimental Teaching Strategy Of High School Physics Students In Groups

In 2017,the Ministry of Education issued a new curriculum standard,namely the Physics Curriculum Standard for General Senior High School(2017 edition).The new curriculum standard not only improves the requirements for subject core literacy,but also revises and strengthens the requirements for physics experiments,especially specifying that senior high school students must do experiments.In the teaching practice,there are many problems in the grouping experiment of high school physics students,such as teachers' insufficient attention to the experiment,lack of design and guidance of pre-class preview,and unitary experimental evaluation.Based on this,it is necessary to study the teaching strategy of physics grouping experiment in senior high school.This study takes constructivism theory and learning motivation theory as the theoretical basis for the study of physical grouping experimental teaching,and USES literature method,classroom observation method and interview method as the research methods to propose corresponding strategies from four aspects,namely,experimental teaching preparation,teaching implementation,effect evaluation and after-class reflection.In the teaching preparation stage of group experiment,the strategies of determining learning objectives based on core literacy,textbook research strategies of multi-direction research textbooks,and task card strategies before class are put forward.In the teaching implementation stage,the strategies of demonstration experiment introduction,problem guided learning,intra-group cooperation and inter-group competition,implicit thinking mode and explicit thinking mode,and experimental data table summary are put forward.The dynamic evaluation strategy is put forward in the evaluation stage of teaching effect.The strategy of event recording is put forward after class reflection.In view of the proposed group experiment teaching strategies,the teaching strategies were applied to four representative group experiments,and the application of these teaching strategies was understood through students' experiment reports and interviews,classroom observation and teachers' after-class evaluation.The research shows that the strategies such as pre-class experiment card strategy,data table summary strategy,question-guided learning strategy and inter-group competition strategy play a positive role in teaching practice,effectively improve students' interest in learning,help students better grasp the physics knowledge,and have certain reference significance.However,in the process of implementing the student grouping strategy and dynamic evaluation strategy,it is found that the effect is not obvious due to insufficient understanding of students,limited class time,weak foundation of students and other factors.
