The Research On The Elements Of High School Chemistry Teachers’ Lesson-saying

Lesson-saying is an important teaching activities to promote the professional development of teachers.Based on the elements of lesson-saying,this article aims to solve the following problems:(1)To learn about the situation of teachers’ lesson-saying,(2)To learn about the cognitive state of teachers,(3)To analyze the differences among the elements of different types of lesson-saying.The author,who has two years’ grade postgraduate courses,has learned a lot of literature reference in this paper.Under the guidance of the theory of cognitive schema of chemistry teachers,from the two angles of teachers who have lesson-saying and researchers on the nearly two national in-service high school chemistry teachers teaching competition in the 68 final text by using the method of text analysis on multi-level analysis and research on the elements of lesson-saying.It can be concluded from the analysis and research that those teachers have elements of lesson-saying: analysis of reaching contents,analysis of the students,teaching objectives and difficulties,teaching and learning methods,instructional design,teaching effect and reflection.The advantages of elements of lesson-saying: To analyze of the nature of the content of a clear subject,to analyze of the distinct knowledge value,comprehensive analysis of knowledge association,break through point analysis.To analyze the existing knowledge and experience of the students finely,classification analysis of students’ specific learning tasks.To design the three-dimension objectives complently.To present teaching method intuitively and clearly.To highlight the two main points in the teaching activity design,heavy and difficult activities to construct both strategies and principles.Aspects to be improved and suggestions are as follows: Study of curriculum standard,detailed teaching materials,improve the content of the specific analysis of the subject.To specify the learning disabilities,refined processing of viscous and difficult,to improve the students in the explicit content of the study related to understanding.By using multiple knowledge representation,the richness of knowledge representation.Careful design the behavior verb,excavate the thought and idea of the subject,set the meaningful learning goal and improve the concrete analysis of the teaching goal.Combining the latest independent teaching method with the conventional guidance teaching method.The analysis of the different teaching methods is improved.With the teaching objectives as a guide,design level operation,guarantee full implementation of teaching objectives,in order to improve the correlation analysis of job design.The basic idea of the teaching goal and the teaching as a guide,to the macro teaching topic as the basic framework,the subject considered closely,and teaching activities to improve the correlation analysis of the design of teaching activities.The problem of multidimensional reflective teaching,explore the reason,put forward the analytical problem solving strategies,so as to increase the correlation analysis on teaching reflection.Lessons theory,material type and reaction type three types of release factors in six aspects of classification analysis five little differences,just every aspect focuses in varying degrees,in the teaching activity classification analysis and design way of thinking in various types of separate releases.
