A Case Study Of Chemistry Classroom Teaching Content Of 《ionic Reaction》 Using CPUP Construct Model

In order to improve the new course chemistry classroom teaching efficiency, we have towalk into chemistry class internal, analyze the chemistry classroom teaching structure, so asto find out the internal rules. Go on with chemistry classroom teaching structure of CPCPmodel, ZhengChangLong professor put forward again chemistry classroom teaching structureof the CPUP model,for chemistry classroom teaching content and teaching behavior researchprovides a quantitative and intensification of thinking and methods.Chemistry class structure of the CPUP model based on the ZhengChangLong professorCPCP model of the construction, to analyze the middle school chemistry classroom teachingContent, or a few Content unit constituted a task Content; One or several tasks contentsconstitute a Plate Content; One or several plate contents constitute a Class Content, ClassContent that this section of the chemistry Class all teaching Content. And establishes thechemistry classroom teaching content structure of the CPUP model.This article chooses the <ionic reaction>as a case, the CPUP chemistry classroomteaching model building, and find out the plate between content, tasks and between the unitcontent, between inner logic, and put forward two new concepts as for UC-Chain andPrC-Chain, To analysis the classroom teaching content, the method of chemistry teachingclassification, and in this article is divided into eight categories unit content, it is respectively(1) Conceptual PrC(2) Analyzing PrC (3) Experimental PrC(4)Phenomenon ExplainablePrC(5) proving PrC (6) Summing PrC (7) Applicative PrC(8) Understandable PrC; On thebasis of this class find three PrC-Chain model respectively is the "concept-analytic" type,"experiment-experimental explain-summary" type,"summary" type; To research theimportance level of PrC of chemistry classroom teaching, and corresponding IBCM level andso as to the matching degree among them. This paper presents a case as a starting point,provides a new idea and research methods to study new curriculum chemistry class.
