Teaching Research On The Core Concept Of Chemistry In High School From The Perspective Of Core Competencies

Since U.S.has promulgated the "national science education standards",many countries have actively carried out based on the standard of science curriculum reform.To 21 st Century,in order to adapt to the development of economic globalization,put forward "to cultivate what kind of people,how to train people",most of the countries,regions and international organizations that the core quality model to personal development and lifelong learning as the main body,should replace the traditional curriculum standard system to disciplinary knowledge structure as the core,the core competence system has become a research hot topic in the field of education in all countries.The formal promulgation of the core competence of the students in China has once again aroused a new round of reform research upsurge.Teaching requirements under the perspective of core competence,we target the educational goals of the course on the formation of behavior habits and the key abilities of students' lifelong development,in the course of teaching,students are constantly provided with opportunities to face problems,analyze problems and solve problems,stimulate their enthusiasm for learning in this process,develop behavioral habits and key competencies in active learning and inquiry.The core concept is located in the center of the concept of chemistry knowledge,principle or method,is of the same type of essential feature of abstraction and generalization,to be able to penetrate the chemical ideas through the content,with a high degree of generality and generally,is a key concept of knowledge has lasting value and value migration.Therefore,core competence from the perspective of teaching research around the core concept,to enable students to build understanding of learning,let students learn how to learn,the implementation of the core competence of middle shool students into the specific subject teaching,cultivating students' scientific literacy,lay the foundation for lifelong learning and training "the all-round development of people" have important significance.Based on the above understanding,this thesis takes the compulsory part of high school chemistry as the research object,and carries out the following problems:(1)What is the core concept of high school chemistry in China?(take an example of a person's teaching edition)(2)From the perspective of Core Competence,classroom teaching research around the core concept whether can promote the implementation of the core competence of the students in chemistry discipline.In order to solve these problems,this study is divided into two parts: theory and practice.The first part,through literature research defines the core competence,core concepts,chemical core concepts,chemical core competence and other related concepts.Through the methods of investigation,test combing and studying the curriculum standards,the core concepts of the compulsory chemistry teaching materials in high school are extracted.The second part,according to the requirements of standard and textbook version of core literacy curriculum content,application of instructional design in practice around the core concept,then under the frame level of chemical core competence,the corresponding test questions are designed to verify the effect of teaching around the core concept on the implementation of relevant core competence.Through the above research,the following conclusions are drawn:(1)There are 18 core concepts in the compulsory part of the chemistry textbook for high school,namely: the amount of substance,the amount of substance concentration,redox reaction,ion reaction,ion equation,organic matter,primary cell,endothermic reaction,exothermic reaction,reversible reaction,addition reaction,substitution reaction,isomer,nuclide,functional group,the periodic table,periodic law of elements,chemical bond.(2)From the perspective of core competence,classroom teaching centered on core concepts can promote students' core quality of chemistry and promote students' learing and teaching.There are the following points:(1)The teaching design around the core concept is more pertinent to the cultivation of students' chemical core competence.(2)It can help teachers think deeply based on core competence,understand the core concepts of middle school chemistry deeply,instruct teachers' teaching and improve classroom teaching effect.(3)It can help students to clarify the concept of related misconceptions,grasp the core concept,make students learn to learn,self-study,and scientific study.
