Analysis Of The High-quality Course "Properties And Applications Of Metal Sodium" In High School Chemistry

With the continuous deepening of the new round of curriculum reform,high-quality classroom has become the goal that people pursue.Many primary and secondary schools and universities are actively carrying out the research and construction of high-quality classroom,aiming to promote the smooth implementation of the new round of curriculum reform and teaching reform by taking "high-quality classroom" as the starting point.This leads us to think: what kind of courses are really good? What problems still exist in quality courses?It is in such an environment that through the analysis of the connotation and evaluation standards of quality courses and other relevant literature,this paper will analyze 9 "nature and application of sodium metal" quality courses from the three dimensions of teaching objectives,teaching links and teaching structure.Through the analysis of teaching objectives of high-quality courses,it is found that teachers can take the development of students' core qualities of chemistry as their teaching objectives in classroom teaching,but none of the 9 teachers can make full use of knowledge content to cultivate and develop the core qualities of chemistry in all dimensions.Through the analysis of teaching links,it can be found that teachers can complete and be scientific in classroom teaching,but there are still some problems in the selection and utilization of teaching situations and classroom summary.Through the analysis of the teaching structure,it is found that the classroom time utilization rate of 9 high-quality classes is very high,and the categories of teachers' language behaviors and students' language behaviors are relatively diverse,teachers can use teaching media reasonably according to the teaching content to be carried out,the evaluation is timely,and the classroom atmosphere is good.But the downside is 9 good lesson in teachers' teaching behavior directly time were greater than indirect teaching behavior,and students in class used to remain in a passive accept the teacher professor knowledge,this phenomenon is not conducive to the student main body status of the play,at the same time,the teachers and students class participation needs to be improved,the type of teacher asking questions ratio remains to be rationalized.Based on the analysis of high school chemistry "the nature and application of metallic sodium" quality class,Suggestions for improvement of classroom teaching were put forward for 9 teachers.At the same time,it also provides some references for front-line chemistry teachers' classroom teaching implementation,and makes up forthe shortage of normal courses with the long length of high-quality courses,so as to continuously improve and improve their own teaching.
