The Study On The Represatation Of Chemistry Problem Of Information-Moving In High Middle School Student

It is a creative activity that the problem is solved, it is an advanced learning process.The problem of studying students solves the course, help to help students to experience and understand the course and method probed into scientifically, the ability to form lifetime study, train students' criticism thinking quality, form " initiative spirit" and " practise ability".Deepenning furtherly with solving studying to the problem, the theory solved about the problem is more and more perfect. On the basis of analysing documents, according to " course that problem solve course perfected constantly to signify this text, view on problem is it run through problem solve all the time to signify ", regard moving the question in chemical information as and study carriers, high school one grade student research object, adopt spoken language report analysis , method , analysis of homework and person who talk to speech of questionnaire investigation carry on research. The result of study shows:1. Three levels of signifying of main experience while solving the question of moving of chemical information of high school student: It is the literal it signify (trying it proceed from top layer characteristic of the question,whose name is only from the literal to come up by question of understanding), model signify (on the basis of the thing that signify literally, type, relevant information of the differentiation question and information of having nothing to do of discerning the question, rejecting the information of having nothing to do, from look for with giving prototyping that information matching by question by existing knowledge, set up issue model), the chemical principle is signified (try according to the problem model established, use the chemical basic principle to ask solving the course of the question concretly).2. Give the similar degree of infonnation and the existing study experience of person who solves problem according to the question in the question of moving of chemical information, can move the question of chemical information and divide two kinds of type similar to top layer of similar type into essence. Discover the high school student is during the process of solving different kinds of information and moving the question, literal to is it have difference basically to signify, but model signify and chemical setting-up that principle signify amount, sign while dawdling correct has obvious differences or not ,etc..3. According to study aristogenesis and learn tired to catch to study spoken report that behavior display of solving chemical problem, find the aristogenesis of studying and study tiredly and catch and have a remarkable difference in such respects as the working ability of information, knowledge structure and moving applied chemistry knowledge and principle method ,etc..According to result that study, this text is it improve high school biochemistry study information move question signify tactics of ability to put forward. Open to improve information working ability of student, is it construct knowledge system of structurization and raise yuans of cognitive competence of student and improve such tactics as students' psychological quality ,etc. to build promptly, can improve student's sign level in the chemical problem is solved. Is it improve high school biochemistry study infonnation move question signify tactics of ability to put forward, its purpose is to expect to offer certain theoretical direction for the fact that improve the ability that students solve the problem in the chemical education of middle school.
