Design And Research On Exploratory Experiments In Grade 2 Junior Physics Based On Learning Cases

With the continuous advancement of learning cases in primary and secondary education,it is universal to apply them in teaching practice.The exploratory experimental teaching based on learning cases refers to the integration of the situation,the learning content and the experiment,which promotes students to actively participate in the learning process in various ways and makes them clarify their own learning goals and the path to achieve the goals in the classroom.Hence,they can learn how to independently carry out the teaching method of exploratory experimental learning.This paper conducts a practical research on the strategy and effectiveness of physical exploratory experiment teaching based on learning cases.In the first three chapters of this paper,interviews and literature research are mainly used to carry out research.In the last three chapters,questionnaires and tests are mainly used as evaluation methods to analyze the data through SPSS software.In the first half of the interview,combined with the suggestions of four physics teachers,the strategy of physics exploratory experiment teaching based on learning cases is obtained :(1)Create problem situation based on our real life;(2)Design learning objectives based on ability cultivation;(3)Simplify evaluation tasks based on specific learning situation;(4)Based on cooperation and communication,to achieve full exploration.With the help of these strategies,eight learning cases are designed,and then the teaching process is designed and applied to practical research.In the process of practice,106 students from a middle school in Chengdu,who have the similar academic level,were selected as the research objects,and the teaching experiment was carried out in one academic year.There were three questionnaire and tests in each semester,which were divided into pre-test,while-test and post-test.According to the experimental results,it is known that the exploratory experiment teaching method of physics in junior two based on learning cases can increase students' interest in exploratory experiment,hands-on ability,the ability to solve exploratory experiment problems and to solve physical problems to a certain extent.However,the improvement of this ability does not change significantly in one academic year,which also reflects that there are still many deficiencies in this teaching experiment,which needs to be improved and promoted in the subsequent practice to provide a good reference for the majority of front-line teachers.
