Investigation And Research On Experimental Teaching Knowledge Of Chemistry Normal University Students

Pedagogical content knowledge(PCK)is the core component of teachers’ knowledge.Experimental teaching knowledge is the Pedagogical content knowledge in a specific field.As is well-known.Teachers’ experimental teaching knowledge is one of the important factors affecting the effective development of experimental teaching.And its formation and development start from the education stage of normal university students.In view of the fact that few scholars can study the current situation of experimental teaching knowledge based on the perspective of teacher education.This paper attempts to start from the perspective of teacher education.A total of 147 normal university students in their junior year of chemical and Material College of SX Normal University were selected as the research objects.The present situation of experimental teaching knowledge development of normal university students was evaluated by developing corresponding questionnaire.Furthermore,some suggestions are put forward for the development of experimental teaching knowledge of normal university students.The process of this study is mainly divided into the following steps: Firstly,on the basis of the comprehensive domestic and foreign literature,the research problems of this study are clarified,and the specific research ideas and methods of this study are determined.Secondly,on the basis of relevant theories,the connotation and elements of experimental teaching knowledge are defined,and on this basis,the evaluation index system of experimental teaching knowledge of normal university students is established,the questionnaire which can be used to test the experimental teaching knowledge of normal university students is developed,and the analysis method of test results is further determined Thirdly,the experimental teaching knowledge of normal university students is evaluated by using the developed questionnaire,and the interview method is used as the auxiliary data collection.Fourthly,in order to comprehensively describe the development status of experimental teaching knowledge of normal university students,the overall analysis,factor analysis and structure analysis of the survey results were carried out,in an attempt to clarify the status quo of experimental teaching knowledge of normal university students from the macro,medium and micro levels The specific method is: assign points to the answers of normal university students by using the established scoring standards and input the original score into Excel,and then import it into Winsteps software for a series of operations,so as to obtain the overall development status of experimental teaching knowledge of normal university students SPSS software is used to analyze the answers of normal university students to each question in the questionnaire,so as to get the development status of the elements of experimental teaching knowledge of normal university students.The PCK analysis graph proposed by Park was used to analyze the experimental teaching process designed by normal university students,and then the development status of knowledge structure of experimental teaching of normal university students was obtained.Fifthly,according to the survey results,some suggestions and strategies are put forward for the development of experimental teaching knowledge of normal university students.The results show that:(1)the experimental teaching knowledge of normal university students is measurable;(2)Normal university students have basic experimental teaching knowledge;(3)The overall development of experimental teaching knowledge of normal university students is normally distributed;(4)The development of all elements of experimental teaching knowledge of normal university students is unbalanced;(5)Some elements are missing in the development of experimental teaching knowledge structure of normal university students.Therefore,this study proposes to pay attention to the balanced development of all elements of experimental teaching knowledge of normal university students and strengthen the integrated development of all elements of experimental teaching knowledge of normal university students.
