Information Meaning Theory Of High School Physics Experiment

Physics is a subject which is based on experiment, and it is not only the basis of physical research, but also the foundation of physical teaching. However, it exposes many problems in the present physical experiment teaching.In the actual teaching of physical experiment, although the students show great interest in the physical experiment, due to some traditional experiments which are designed completely or the purpose of the experiment is not clear enough, or the experimental principle is too abstract and so on, it is difficult for students to grasp the contextual physics experiments and construct corresponding physical knowledge when they are doing experiment.How to make physical experimental assisted physics teaching to the greatest extent and to achieve the best effect, it has been a difficult problem that needs to be solved urgently in physics teaching in middle school.According to the above problems, this paper is in the perspective of the meaning of information construction, combined with the present physical teaching in the middle school to analysis the physical experiment teaching process with the application of the constructivism theory in order to provide a feasible method which focus on improving the effect of physics experiment teaching. Take the high school physics experiment as the main research object, this paper summaries the application characteristics of the theory of information meaning construction on the physical experiment teaching.This paper first aims to overview the theory of information meaning constructivism, and understand the basic characteristics of information meaning construction process.Then it analyzes the feasibility of the application of information meaning constructivism on the high school physics experiment. Through the interviews, questionnaires and other methods to find the main difficulties and the solutions in experiment teaching.Analysis found that the experiment effect is not ideal, difficult to improve student test scores and the phenomenon on the disconnection between the physics knowledge and physics experiment due to the unscientific design of some physical experiment.Then this paper applies the laws of information meaning construction to analysis several typical high school physics experiment and starts from the theory of constructivism, in the view of creating situations, building support and meaning construction to study on physical experimental information meaning construction process, analysis the psychological foundation of the physics experiment comprehensively and systematically.This paper improves the experiment of research on flat throwing motion by using the method of creating situation and setting data,improves the experiment on verification the law of conservation of momentum using innovation experiment device and proportion method,improves the experiment of research on relationship between acceleration and quality and force using integral method and multiple method, improves the experiment of the research on relationship between acceleration and quality and force using the partial integral method and combined with methods of thinking and experiment, improves the experiment on verification the conservation law of the mechanical energy by changing the method of data process and installation of experimental equipment.From three part in the experimental instrument, experimental procedure and experimental data processing to discuss on the construction of law and to apply the constructivist theory into the process of physics experiment teaching.In the end, this paper finds out the laws of the construction of the information meaning and universal methods in the practical teaching of the middle school physics experiment:1)Improve the experimental equipment and simplify the experimental procedures to improve the students’ enthusiasm for experiment;2)Create the physical situation which is familiar by students and build a bracket between the old and new knowledge;3)Improve the experimental data setting and experimental data processing method;4)Combine physical thinking with experiment to promote the construction of physical knowledge.
