Teaching Research On The Cultivation Of Chemical Core Literacy Of Freshmen In Senior One

The curriculum standards of Senior high school chemistry point out that the five dimensions on core literacy of chemistry,including macro-identification and micro-analysis,changing concept and balance thought,evidence reasoning and model cognition,experimental exploration and innovation Consciousness,and scientific spirit and social responsibility.However,how to accurately implement chemistry core literacy into classroom teaching and specific teaching module is still the most concerned problems for chemistry teachers who work in the front line of education at present.The purpose of this study is to serve teaching,improve teaching quality and promote students' core literacy of chemistry.on the basis of explaining the connotation of chemical core literacy in detail,taking "redox reaction" a compulsory course 1 in the Human education edition as an example.the specific manifestations and causes of learning difficulties in "redox Reaction" of Freshmen in senior high school were investigated through questionnaires and interviews,and the cultivation of chemical core elements was put forward.Nurturing methods can help students solve the learning difficulties in redox reaction.By interpreting the chemical core literacy contained in "redox reaction",this paper puts forward specific training strategies such as situation creation,model construction,question string design and so on,and integrates these strategies into the teaching design of redox reaction.Guiding classroom practice.Through classroom practice,this paper reflects on teaching strategies and teaching process,and provides some reference suggestions for the cultivation of chemical core literacy of freshmen from the perspective of their cognitive development level.On the contrast the experimental class to the control one,it is found that the strategy of this paper can help students master the effective knowledge points of redox reaction and produce a positive effect on the improvement of students' achievement.The comparative analysis between the experimental class and the control class showed that the teaching strategy of chemistry core literacy of this paper had a positive effect on the promotion of students' interest.The results of interviews with teaching teachers showed that the training strategies of core literacy proposed in this paper can make up for the shortcomings of traditional classroom to a certain extent.The results of interviews with students in the experimental class showed that the teaching strategies proposed in this paper play a positive role in improving students' chemical core literacy.Generally speaking,students' difficulties in learning the concept of redox reaction havebeen solved;the combination of theory and practice in teaching has not been closely solved to a certain extent;students' ability to analyze and solve problems has been improved;students' ability to innovate has been improved to a certain extent.Students' chemical core literacy has been cultivated and improved.
