Novice Teachers "Making Of CO₂" Classroom Case Study Of The Effectvenes Of Teaching Behavior

CPCP model of chemistry class structure is a chemistry class hosted a series of specific teaching tasks which are divided into different teaching activities of the parts. Each part is composed of several teaching behavior chains. The final refinement of each teaching behavior chain is converting into a number of teaching behavior pairs. Therefore, on the basis of CPCP model, high school chemistry classroom under the new curriculum will enlarge and clearly show the logical structure of classroom teaching, design intent of teachers and features of teaching practices.In this article, we applied CPCP model to analysis the inherent characteristics of'Preparation of CO₂'by a new teacher.The class is divided into four parts; explore ideas, the exploration of preparing CO₂, demonstration experiment, and summary. Each part is interrelated in order to inspiring students to think from the point of contact and build new knowledge.The designs of learning task are pay attention to the subjectivity of students, the alternating of core tasks and important tasks (general task), and the reasonable coordination of teaching time. But there are other issues, for example, simplex learning style, too much core tasks, and the confusion of important tasks and general task.Teacher-oriented teaching behavior dominated the class; student teaching behavior based on the exchange is only a report. In addition,'one asks the others answer'an inefficiency teaching behavior appeared in this lesson more than once.The number of teaching behavior chains is obviously more and the time is shorter. Except for individual chains, most of the teaching behavior chains are similar in times, and the matching attribute of contents and teaching behavior chains on teaching time needs to be improved.
