Teaching Practice Of Review Lessons On Chemistry Experiment Among Students In Senior Three Based On Core Accomplishment Of Discipline

With China's education developing remarkably in recent years,to meet the needs of training diversified and high-quality talents in new economic and social situation,the Ministry of Education issued the Core Literacy of Chinese Students' Development in September 2016,proposing to cultivate "all-round development people".In order to better implement the core literacy of students' development,five-dimensional core qualities of chemistry are proposed in the "Chemistry Curriculum Standards for Ordinary Senior High Schools" issued by the Ministry of Education in January 2018,which are "macro identification and micro analysis","changing ideas and balancing ideas","evidence reasoning and model cognition","scientific inquiry and innovation consciousness" and "scientific attitude and social responsibility".As new curriculum reform has been pushing on,high school chemistry experiment teaching practice,an important means to improve students' core quality of chemistry,should also be valued.However,at present,most of the studies on the experimental review are limited to empirical and speculative results,while few practical studies are really putting core literacy into the experimental review lessons.Based on the core literacy theory,the author studies the teaching strategy and pays special attention to the teaching practice of experimental review in Senior Three students.Firstly,by consulting and analyzing the current situation of core literacy and chemical experiment review at home and abroad as well as discussing the necessity of chemical experiment review for developing students' core literacy in Senior Three,the purpose and significance of the research have been made clear.Secondly,with the progressive development of three theories: core literacy,discipline core literacy and chemistry core literacy,this paper expounds the theoretical basis of the research.Through interviews with Senior Three chemistry teachers and questionnaires to Senior Three students,this paper analyzes the development of core literacy and the current situation of chemistry experiment study.And after analyzing the investigation results,some suggestions are given on the present situation of experimental study as well as the development of students' chemistry core literacy.Combined the results of the questionnaire survey with the current situation of experimental study in Senior Three,this paper explores the teaching practice on experimental review in Senior Three.The research content includes the review strategy of chemical experiment teaching under the core literacy,teaching links,designed ideas of experimental review,etc.Taking "Special Topic 4-Organic Preparation Experiment" for example,combined with the detailed teaching process,it fully embodies that the theory is implemented in the real review.In order to verify the practical effect,this paper analyzes it from two angles: student evaluation and test scores.Through the analysis of the practice results,the author finds that with the core quality of the subject and adopting appropriate experimental review strategies,compared with the traditional experimental review teaching,the teaching and learning effect has been greatly improved in this way.Finally,summarizes about the research conclusions,innovations and shortcomings are made.Through the research,the author concluded that in the experimental review stage of Senior Three,the review teaching based on the subject core literacy is beneficial for students to master the core knowledge of chemistry experiment,and can improve students' ability of migration and application and develop the core literacy of chemistry.Moreover,the cultivation of students' chemical core literacy is a long-term process.This study is only a preliminary exploration of the teaching practice on teaching practice on experimental review of Senior Three based on core literacy.It is hoped that more teachers,experts and scholars will join in the research in the future.Explore new practical teaching methods and review strategies to achieve the purpose of cultivating core literacy.
