Research On Chemistry Teaching Design In Middle School Guided By TPACK Theory

Nowadays,with the continuous development of educational informationization,the requirements for teachers' professional development are also constantly improved.The effective integration of modern information technology into classroom teaching has become a necessary skill for teachers' career development.Therefore,the application of TPACK theory in subject teaching is very important for teacher development.On the basis of systematizing and referring to the existing research results at home and abroad,the current research status of TPACK theory at home and abroad is analyzed,and it is found that the application of integrating technology into middle school chemistry classroom is less.This research takes the chemistry teaching design of middle school as the research object,takes TPACK theory as the guidance,combines constructivist learning theory,metacognitive theory and comparative empirical teaching in the chemistry classroom environment of middle school,and focuses on the chemistry teaching design of middle school under the guidance of TPACK theory.Two of the four teaching materials of senior chemistry elective course were selected for the new teaching design.The practical teaching activities were carried out in the first-line classroom to analyze the integration effect of the new technology and the middle school chemistry teaching.Besides,the methods of classroom observation and analysis,student achievement analysis and teacher questionnaire survey were used to provide the analysis basis for the research effect of this paper.This paper can be divided into five parts: the first part is the introduction.By reading and sorting out relevant research literature,this paper analyzes and summarizes the research status of TPACK theory at home and abroad,and puts forward the research background,research purpose and significance,main research contents and methods,and research ideas of this paper.The second part is the research theoretical basis and the definition of core concepts,introducing the theoretical basis of this study and defining the core concepts of TPACK theory.Refer to relevant data and conduct integrated analysis.The third part is the high school chemistry teaching design case under the guidance of TPACK theory.While deeply studying the chemistry teaching content,it integrates the new technology into the middle school chemistry classroom teaching.The teaching of "application of pH" and "factors affecting hydrolysis of salt" in "principles of chemical reaction",the fourth elective course of chemistry in senior high school,were mainly studied.The fourth part is a concrete empirical study,which conducts field high school chemistry classroom teaching practice with high school chemistry teaching design cases under the guidance of TPACK theory.The empirical part is conducted in a middle school in W city.After the practical teaching is completed,the correlation analysis of the two classes is carried out,and the relevant conclusions are drawn through the data analysis of students' test scores and teachers' questionnaires.The fifth part is the conclusion and prospect part,mainly introduces the conclusion of this paper and the reflection and prospect of the article.There are three conclusions in this paper: first,under the guidance of TPACK theory,middle school chemistry teaching can stimulate students' learning interest and enthusiasm,and improve students' scores to a certain extent;Secondly,high school chemistry teaching under the guidance of TPACK theory can improve students' manual operation ability and develop their experimental skills.Finally,the middle school chemistry teaching model under the guidance of TPACK theory won the recognition of more front-line teachers.This research is a new exploration of the integration of modern information technology and middle school chemistry teaching practice,and has certain research significance and value.The new teaching design developed in this paper combines new technologies such as micro video,multimedia display,digital experiment and virtual laboratory,hoping to provide certain reference value for the future teaching of middle school chemistry teachers.
