The Evaluation And Strategy Research Of Effective Questioning In Senior High School Chemistry Classroom

Effective questioning of teachers in classroom can lead students to think,and develop students ' awareness of problems.It is also an important bridge to communicate between teachers and students.Also Effective questioning of teachers in classroom has drawn the attention of a broad line of teachers and educational researchers.The effective questioning in the classroom can not only arouse the students ' interest in chemistry but also improve their thinking ability.In addition,this can develop students ' awareness of problems and improve their ability to analyze and solve problems.But in the actual teaching observation,there are many inefficient and ineffective questions in chemistry class.The author's study on the effective questioning of senior high school chemistry class mainly includes the following parts.The first and second chapters of this thesis mainly carry on the theoretical research of the subject.And also it helps us to understand the results of the research on concept,definition,function,standard and strategy of effective questioning at home and abroad.Through questionnaire,the third chapter mainly helps us understand the author's questioning situation in the classroom of the school,thus,we can provide practical basis for the establishment of evaluation scale.The fourth chapter is developed according to the question implementation procedure.The index system of effective questioning evaluation is constructed from the five dimensions of problem designing,process questioning,student answering,teacher's answering and questioning effects.Finally,19 evaluation indices are established and the weights are assigned by the rank and operation method.Therefore we can get the evaluation scale of effective questioning in high school chemistry class,and these can be carried on the preliminary application research to the scale table in the fifth chapter.The sixth chapter focuses on the third chapter investigation and the problems exposed in the scale application process,from the aspects of the problem designing,the implementation of questioning and teacher reflection,and so on,and analyze these from the theory and examples.In this chapter,the author gives the corresponding operational strategies and suggestions from the aspects of chemistry teaching.The author unifies its own teaching practice to do some research on the evaluation and strategy of effective questioning based on the research of other researchers.The author pays more attention to the construction of evaluation scale so that she can have a certain evaluation function to teaching and this can also make the research system of effective questioning rich and perfect.
