Research On The Practice Of HPS Teaching Mode Based On Micro-course In Chemistry Teaching In Senior High School

Information globalization is an important trend of today’s social development,and the cultivation of students’ scientific literacy is required by the standard of educational reform in China.This study adopts HPS teaching mode based on micro-class to improve and perfect the disadvantages of traditional teaching mode,realizes the organic combination of traditional teaching and information-based teaching,integrates chemistry history into chemistry teaching to create a real chemistry inquiry situation,and integrates micro-class and HPS teaching mode into chemistry classroom teaching,so as to cultivate students’ core literacy of chemistry.This study uses the literature research method to sort out and define the research status and related concepts of HPS teaching mode and micro-course at home and abroad,and analyzes the correlation between this research model and constructivist learning theory,scientific essence view and situational teaching theory,so as to clarify the research value and research significance.Before teaching practice,the feasibility analysis of HPS teaching mode based on micro-course was carried out,and the learning status and needs of students were understood through student questionnaire surveys and teacher interviews,and the necessity of organic combination of the two was further clarified according to the characteristics of micro-course and HPS teaching mode.Define the design principles of micro-course and HPS teaching mode,and construct the basic practice process of HPS teaching mode based on micro-course.Finally,"The Properties of Ammonia" and "The Simplest Organic Compound: Methane" in the second volume of high school chemistry compulsory in the People’s Teaching Edition were selected as actual teaching cases,and the practical effect was comprehensively evaluated and summarized by the teacher’s listening evaluation table,the comparison of the results of the experimental class and the control class,and the teacher’s post-practice interview.The results of teaching practice research show that the HPS teaching mode based on micro-lessons has a certain effect on students’ academic performance,effectively promotes students’ understanding of the essence of science,and improves students’ knowledge and cognition.In the summary and reflection,the advantages and disadvantages of this research model are pointed out,which provides a direction for the follow-up research,innovates on the basis of the traditional teaching model,and provides new ideas for the construction of the educational model.
