A Study On Classroom Teaching Of "Learning From Side And Side" In Chemistry Of Senior High School

Chemistry "lectures and experiments at the same time" classroom teaching is an important form of chemistry teaching. In chemistry "lectures and experiments at the same time" classroom teaching, teaching and students’ experiment operation cross. That is helpful to reflect "on the basis of the experimental" chemistry discipline characteristic, but also to reflect the students’ subjectivity. So the study of chemistry "lectures and experiments at the same time" classroom teaching is an important content of basic curriculum reform.This study tries to analyze the basic process and main features of "lectures and experiments at the same time" classroom teaching and puts forward some teaching Suggestions.The author has read a lot of works about the chemical experiment teaching and the analysis of teachers’and students’ behavior in classroom teaching. In addition to reading, the author has carried on the massive classroom observation and video records. After that, the author uses CCITIAS to make quantitative analysis of four classroom teaching records with a typical significance.Research Findings:The process of typical "lectures and experiments at the same time" classroom teaching includes "create situation and ask questions, autonomous learning and design scheme, operate experiment and probing discovery, exchange discussion and draw a conclusion, inductive summary and migrating application". The characteristics of the typical cases of "lectures and experiments at the same time" classroom teaching are the following. Students learn by doing. Learning and doing is an inalienable organic whole. With the students experiment throughout the classroom teaching, the teaching is carried out around student experiment. Teachers’ language behavior is still the most important part of classroom teaching. Teachers use the way of asking questions and direct communication to promote teaching and help students complete knowledge construction. Chemistry "lectures and experiments at the same time" classroom teaching has build harmonious classroom atmosphere. Positive integer data frequency is very high, but defect lattice data frequency is very few.Research suggestions:In Chemistry "lectures and experiments at the same time" classroom teaching, teachers should pay attention to designing the students experiment cleverly. Teachers should pay attention to the principal position of students learning. Teachers should design interactive teaching behavior carefully. Teachers should Build the teaching form "group cooperative learning" and skillfully correctly deal with emergency.
