Teaching Design And Practice Research Based On Chemistry Core Accomplishment

With the continuous deepening of basic education reform in China,the word “core literacy”has attracted much attention,and the cultivation of students' core literacy has become the common mission of the education sector.In high school chemistry courses,Cultivating students' core chemistry qualities has become the primary task of chemistry teaching.The 2017 version of the curriculum standards proposes to train students to form the correct values and necessary qualities,developing students' core literacy.In reality,the development of high school students' core literacy is not perfect,so teachers need to improve the quality of classroom teaching to improve the cultivation of core literacy.Compared with the new curriculum reform concept,at present,most of high school chemistry classrooms adopt traditional teaching mode,attach importance to the transfer of knowledge and skills,neglect the cultivation of students' comprehensive quality and ability.Students' scientific inquiry and innovation ability failed to develop,unable to cultivate students' quality of chemical thinking.Therefore,how to cultivate students' chemistry core quality in the high school classroom has become an important topic in high school chemistry teaching.This article first analyzes the current status of core literacy at home and abroad and core literacy in chemistry,defined the concepts of core literacy,chemical core literacy,etc.by analyzing and studying the current status of core literacy at home and abroad.By analyzing the research status of the content of "ion balance in aqueous solution",taking "ion balance in aqueous solution" as the carrier,on the basis of constructivism,humanism and lifelong learning theory,the teaching modes of inquiry and cooperation are adopted.According to the current situation of cultivating students' core accomplishment in chemistry through the questionnaire method and after class interview method,it is found that there are several current situations of students' chemistry teaching:(1)the single mode of thinking,(2)knowledge migration ability is poorer,(3)experiments to explore the ability is not strong,so,This study proposes targeted teaching principles and teaching strategies.from the angle of educational psychology to put forward the research plan of training students' chemical literacy core,taking a senior highschool student in a middle school in Hezhou,as the research object,and to investigate students' chemistry core accomplishment respectively,conduct practical research based on the constructed teaching strategy,based on the comparison of the survey and test(pre-and post-test)of the chemistry core literacy training of high school students,combined with the students' academic achievements and after-class interviews to comprehensively analyze the implementation effect.Research indicates: Through the designed teaching case,change the traditional teaching mode,inquiry classroom teaching to stimulate students' interest in chemistry learning,can better develop students' chemical core literacy.Through the pre-and post-test analysis of the development of the core chemistry of the experimental class and the comparison class,it is found that the teaching principles and teaching strategies proposed in this study have a significant role in promoting the development of students' core literacy,can better train students' core literacy ability,but it needs to be gradually strengthened later.Teachers need to change their teaching philosophy,according to the requirements of the new curriculum,perfect teaching strategies and teaching methods.At present,the research on core literacy in China is not perfect,and research time constraints and my limited research level,the teaching principles and strategies proposed in this paper need to be further practiced and improved in the future teaching process.
