Research On Effects Of Organic Schema Transformation On Chemistry Problem-solving For Senior High Students

With the direction of schema theory and cognitive psychology ,the paper focuses on the fringe discrepancy among gifted,average and problem students in senior three when solving organic transformation schema in chemistry study. The paper mainly adopts the research techniques of group testing and case analysis.The author proposes that:①Organic transformation knowledge in student's cognition structure is the base of organic chemistry problem solving;②How the organic transformation schema are constructed in student's cognition, may have an essential impact on organic chemistry problems.The result of study shows:①The investigation of organic study reflects students: the difficulty in integrating organics quality, the difficulty in referring the organics transformation, the difficulty in migrating the prior knowledge into the new organics.②As far as the organics transformation schema is concerned the gifted students are better than the average and problem students in quantity and quality . The weaker of the knowledge structure and transformation have been caused by inaccurate organic concept and lower extension.③Ethylene substance transformation shows the direct impact on the chemistry problem.④Students are guided to aggressively arrange the prior knowledge structure in teaching; The declarative knowledge can be made into a network about the organic concept's style and attribute; The meaning groups and transformation schemas, which are gained by solving chemistry problems, promote the solving of organic problems.⑤About the developing organic transformation in problem solving ,the three types of students all have gone up, the problems student are developing organic transformation promotes the solving. How the organic transformations may have an essential impact on organic chemistry problems.
