Analysis Of The Characteristics For The Importance Degree Of Teaching Content In Middle School Chemistry Classroom By Proficient Teachers

Teaching content is a carrier to achieve teaching objectives, is the most importantpart in classroom teaching,and its organization directly impacts on teaching objectivesand the efficiency of teaching.A lesson is consisted of a series of primitive systems.Different combinations of the importance of primitive content directly affect thedistribution of teaching content, distribution situation of chemistry teaching contenthas a certain impact on classroom teaching quality.This study selects32high school chemistry lessons as sample taught byproficient teachers,uses literature analysis method,classroom teaching observationmethod,statistical analysis method and description method,and eventually comes tothe distributions and differences of importance of teaching content in concept andprinciple classes,element compound classes,normal,classes,quality classes,maleteachers’courses and female teachers’ courses.The research shows that different degrees of importance of teaching contentshowing a different distribution in the different type lessons;the differences betweenconcept and principle classes and element compound classes is mainly due to thedifferent type of chemical knowledge,the main differences between quality classesand normal classes is mainly due to the different methods;female teachers pay moreattention on training chemical operations skills.
