The current compulsory education chemistry curriculum standard(2011 Edition)stipulates that the curriculum goal is "to improve the scientific literacy of students in the compulsory education stage".However,the chemistry curriculum standard for senior high school(2017 version)(hereinafter referred to as the "new curriculum standard")began to emphasize the curriculum concept of "taking the development of core literacy of chemistry as the main purpose".In recent years,in order to effectively link the compulsory education chemistry curriculum with the general high school chemistry curriculum,it has become a hot research topic to cultivate the chemistry core literacy of junior high school students.Chemical history is an important course resource,which can not only explain the origin and development of chemical knowledge,but also serve as a bridge between chemical education and humanistic education.The history of chemistry has an important educational value for the cultivation of students’ core quality in chemistry.It is not only an important content of chemistry curriculum,but also an important means applied in chemistry teaching.Therefore,how to effectively train junior high school students’ chemistry core literacy through chemistry history is a subject worthy of study.Through the investigation of the current situation of chemistry history education and the cultivation of chemistry core literacy in junior middle school chemistry teaching,the following results are obtained:(1)teachers agree with the value of the cultivation of chemistry core literacy;(2)students think it is necessary to carry out chemistry history education in chemistry classroom;(3)teachers can use a variety of videos,classic experiments,storytelling and other teaching methods Learning methods help students learn the history of chemistry.On the basis of constructivism theory,heuristic teaching theory and situational learning theory,the following teaching strategies are put forward:(1)teachers can consciously penetrate the evolution of chemical discipline thought and the exploration ideas and models of core concepts to cultivate students’ change concept and balance thought and evidence reasoning and model cognition Literacy;(2)teachers can cultivate students ’scientific exploration and innovation awareness literacy by reproducing the exploration process of classical theory and the scientific spirit of scientists ’ brave innovation;(3)teachers can cultivate students ’ scientific attitude and social responsibility literacy by infiltrating the outstanding contributions in the history of chemistry and the promotion of chemical development on social development;(4)Teachers can cultivate students’ quality of "macro identification and micro analysis" by introducing the development history of theory alternation and negation in the history of chemistry.According to the investigation and teaching strategies,the paper selects the ninth grade chemistry subject of human education edition as the teaching design to integrate into the education of chemical history,and selects two junior three parallel classes of Xiangcheng junior high school as the teaching practice research object,and carries out a semester of teaching practice.The experiment teaching was carried out in the experimental class and the routine teaching was carried out in the control class.At the end of the teaching practice,the questionnaire analysis is carried out for the students in two classes,including: the students’ understanding of the chemical history and the core literacy of the chemical discipline,and the feedback of the teaching effect of the chemical history education to cultivate the core literacy of the chemical discipline.The results show that: the history of chemistry plays an important role in the cultivation of students’ chemical scientific literacy;through the history of chemistry,junior high school students’ chemical scientific literacy can be cultivated,so as to improve students’ chemical subject core literacy;teachers can integrate the relevant teaching strategies into the education of chemical history from the angle of cultivating students’ chemical subject core literacy,so as to promote the improvement of students’ chemical subject core literacy Liter. |
