The Research About Original Physical Problem Based On Cognitive Psychology

The newly released Core Literacy imposes new and higher requirements on students: Students can not only solve typical physics exercises,but also use physics knowledge to solve problems in our real life.Currently,In the field of physics education in middle schools,Original physical problems are regarded as an effective tool to cultivate students' ability to solve physical problems.This paper mainly studies the main influence factors of solving the original physical problems and the normal methods of finding out the solutions to the original physical problems.Based on the cognitive psychology perspective,our team analyzes the process of solving the original physical problems,and considers that the understanding of the concept as well as the law is the main influencing factor of solving the original physical problems.The ortinary strategies for solving original physical problems has been summarized by combines the features of cognitive psychology and physics.On this basis,the representation of declarative knowledge in cognitive psychology and the classification of educational objectives in Bloom are synthesized.three kinds of test questions has been Compiled according to the concept law involved in the original physics question: the test question of concept law understanding,the "execution " test question,the "implementation " test question.Students in four classes in a general secondary school were tested and the following conclusions were drawn:(1)In general,most students are weak in solving original physics problems;Students only stay at the memory level and can't reach the understanding level;Most students have a better able in solve familiar executive problems,while have a weak ability in solve unfamiliar implementation problems.(2)The students who have a good understanding of the concept law have a strong ability to solve the original physics problems and implement the class problems.(3)Students with strong ability to solve the implementation problem are also more capable of solving original physical problems.(4)The students who can solve the executive problem are not always able to solve the original physics problem better.Based on the above conclusions,the following suggestions are put forward for physics teaching in middle schools:(1)Pay attention to students' understanding of the physical meaning of concept and regularity.(2)Proper use of New situational problems in Teaching to develop students' Physics ability.(3)In the examination,we should increase the proportion of the implementation problem and strengthen the training of the ability to solve the problem.
