Design Of Classr Oom Activities Of "Electrochemical Foundation" Unit Based On The Core Accomplishment Of Chemistry

In order to implement the fundamental task of "cultivating talents by virtue",chemistry curriculum standards for ordinary senior high school(2017 edition)points out that chemistry is an important part of senior high school curriculum and undert akes the important task of developing students' core quality of chemistry.How to i mplement the core accomplishment of chemistry in high school chemistry teaching is a question that every chemistry teacher should think about and study.Classroom activities are an important carrier for teachers to carry out classroom teaching.Ho w to design classroom activities in chemistry teaching so as to develop students' c ore qualities of chemistry is an important research content.This paper firstly sorts out the literature on the core accomplishment teaching of chemistry and the teaching of "electrochemical foundation" unit,and finds out t he advantages and disadvantages of the existing classroom activity design of "electr ochemical foundation" unit.Secondly,it provides ideas for the design of unit classro om activities to promote the core quality of chemistry,including three key points.First,it focuses on the life around students and selects common phenomena and pr oblems in life for exploration.Second,the attention links the industrial production,s tudies in order to apply;Third,the cognitive model is constructed by contrastive str ategy on the basis of known knowledge and experience.In order to promote the de velopment of students' core accomplishment in chemistry,two classroom activities,"galvanic cell principle" and "electrolytic cell principle",were designed after analyz ing the curriculum standards and textbook contents,and the performance of core ac complishment in chemistry discipline.Finally,this paper designed classroom activitie s for practical teaching,through the quasi-experimental method in the experimental group to implement the classroom activities designed in this study,the control grou p in accordance with the natural state of school teaching.The self-designed questionnaire was used to test the students in the two classes,and combined with the anal ysis of the students' learning plans in the experimental group,to explore whether t he classroom activities designed in this paper promote the development of students' core literacy in chemistry.Through the analysis of the results,this paper found that the test results of th e students in the experimental group were better than those in the control group,which proved that the unit classroom activities developed in this study effectively promoted the development of the students' core literacy in chemistry.Finally,the pa per puts forward several aspects that should be paid attention to in the developmen t of the "electrochemical foundation" unit classroom activities based on the core ac complishment of chemistry discipline :(1)based on the teaching materials,graspingt he theme;(2)design real problem scenarios to improve students' quality of "scientifi c spirit and social responsibility";(3)develop students' quality of "macro identificati on and micro exploration" by combining macro and micro;(4)guide experimental i nquiry and strengthen students' quality of "scientific inquiry and innovation conscio usness";(5)construct cognitive model and develop students' "evidence reasoning and model cognition" quality.
