Study On Chemistry Teaching Based On Evidence Reasoning And Model Cognition

As an important part of the cultivation for middle and high school students,chemistry core literacy has become a hot research topic at home and abroad.As one of its important components,the cultivation of "evidential reasoning and model cognition" has been proved to be a unique method for forming student`s thinking ability.Based on the detailed analysis and review of core literacy,this study preliminarily understood the current situation of literacy for high school students through questionnaire survey and data analysis.Put forward some corresponding core literacy based teaching strategies based on the analysis of the influencing factors,and carry out classroom teaching activities.Eventually,the implementation effect of the teaching strategy in the cultivation of students was verified through observation and interview after class.This paper was divided into five parts:After a detailed search and reading of relevant research literature,this paper expounded the research purpose,research background,and practical significance of this study,and formulated the ideas and methods.Related concepts and theoretical basis.The purpose of reading and analyzing the related concepts involved in this study was to find and provide theoretical support for the research process of this study.This part was the theoretical foundation,which lay the foundation for the depth and comprehensiveness of this study.It was about the investigation and analysis of the current situation of "Evidential reasoning and model cognition" chemistry teaching.This paper analyzed and designed the specific content of the research,designed the investigation paper which could deeply study the students' understanding and current situation of this knowledge,and carried out the investigation of students' understandings.After that,SPSS,Excel and other statistical methods were used to process the collected and sorted data,analyzed the students' current understanding of mentioned term,and summarized the influencing factors.It was found that students' knowledge and understanding of Evidential reasoning with model cognitive literacy needed to be strengthened;Through the analysis,it was found that the cultivation and understanding of students in this aspect are influenced by many aspects.The research on teaching strategies based on evidence reasoning literacy and model cognitive literacy.Aiming at the problems existing in the cognition of core literacy,the paper put forward the corresponding teaching strategy,and used the teaching strategy to carry out classroom teaching research activities in H middle school.The course case was made by combining the course “ethanol” and “the periodic law of elements”;The evaluation was carried out through lectures,observation after class and interviews.The strategy could promote the cultivation of students' core literacy to a large extent,and provide examples and reference for the chemistry teaching in senior high school.Conclusion and thinking.Through the way of summary,the paper evaluated the results obtained in this paper,found out the shortcomings,and some suggestions were proposed for the further researches.
