Research On Teaching Behaviors In Chemistry Review Lessons Based On Construction

The classroom teaching behaviors, a critical component of teaching and learning research,consist of the teachers teaching and students’ learning. Teaching behavior is an important mode for the teachers to embody educational concepts and complete teaching tasks, as well as a key point to achieve the teaching objectives in one lesson, of which, the implementation conditions will have a direct effect on the teaching results.Chemistry review lesson is a summary and promotion of new teaching knowledge, which plays a very important role in helping students to construct a structured knowledge system and promote the comprehensive ability of students. Review lesson teaching directed by basic chemistry concept can help the students with learning factuality chemistry knowledge and basic skills, promoting the intellectual development, improving scientific literacy and the efficiency of both teaching and learning.The classroom teaching behaviors complying with the features of this research were designed in this paper by the combination of the domestic and overseas literature concerning classroom teaching behaviors with the features of chemistry based on the comprehensive consideration of features, essence and requirements established by the chemistry concept. Such classroom teaching behaviors include 8 teaching behaviors, i.e., teaching content, transient mode,conclusion mode, teachers’ questioning, students’ answering, students’ task completing activities,classroom quietness or chaos successively, of which, each of the 7 behaviors are divided into more detailed sub-behaviors. This research selected three chemistry review lessons with class video constructed on a basis of chemistry concept as the object, conducted coding analysis on the classroom teaching behaviors according to different behavior category, conducted statistical analysis as per occupied time, rate of time occupying, frequency, frequency rate, etc., objectively and quantitatively discovered the true circumstances of the teaching behaviors in chemistry review lessons constructed on the basis of concept and then made a corresponding evaluation.According the research and analysis, the teaching efficiency of such chemistry review lessons constructed on the basis of concept is higher. The student activities in the classroom will be the center during classroom teaching, and it’s necessary to pay attention to the students’ automatic activities and dialogue behaviors between the students and teachers. In addition, the teachers should lay emphasis on leading and creating the learning circumstances by questions,designing various tasks and other methods to promote the teaching process and develop the students’ thoughts, among which, promoting conclusion of teachers’ concepts, questions at highthinking level and various students’ activities are of a critical function for chemistry concept construction of the students.
