It is the latest education teaching concept, teaching to the concrete embodiment of routine teaching has demonstration and led effect for regular classroom teaching, can increase the level of inspiration and promote brought.This topic in jiangsu province in2009, middle school chemistry outstanding class appraisal of14high school chemistry excellent lesson as the research object, the14class teachers in14respectively from jiangsu province, jiangsu province to some extent reflects high overall level of chemistry classroom teaching. Using the author construct high school chemistry outstanding class teaching evaluation index system of14lesson from the classroom teaching effectiveness, leading, three dimensions of case analysis, points out the advantages and disadvantages of14lesson. And according to the results of analysis puts forward improving high school chemistry classroom teaching efficiency strategy.Analysis results show that:(1)14class teaching objectives can do from three dimensions to comprehensive building. Constructed the teaching goal of the most can meet curriculum standards, accord with teaching materials and the students’practical, but also have individual class the teaching goal for knowledge request too exorbitant, deep, beyond the curriculum standards, beyond the students’practical level.(2)14class is at the choice of teaching content to do with practice, to life in display teaching content, are able to pay attention to the chemical knowledge system and teaching content item, most lecturing correct, but individual class exists scientific errors.(3) in the process of teaching, and class are fully utilize chemistry experiment and multimedia teaching resources to enrich teaching. Value of teaching situation, teaching situation close to create life of students in students’ cognition, but conflicts caused to stimulate students’ cognitive desire slightly enough. Regarding the classroom generative resources attention is insufficient, the teaching plan to attach too much importance to default. Pay attention to experiment, to explore issues determine proper, suitable for exploring expanding, but to explore some problems on arrangement.(4) because outstanding class public properties, so all class participation is very high, active thinking, able to ask questions, good opinions, willing to participate. Knowledge flexibly to analyze and solve problems. Overall are very good teaching effect.(5) all of the great lesson in his classroom teaching are manifested in the latest advocated by the new curriculum reform education teaching idea, pay attention to science inquiry, trains the student to analyze, to solve the question ability, practice ability; The value chemical experiment resources utilization, adopt points the way for cooperation experiment cultivation of students’cooperation and communication ability; Attention situation creation, etc. Individual lessons can realize in the teaching innovation.(6) each lesson has many advantages, for class changes with the implementation of the notion of using, for teaching innovation, are worth extending.
