| Knowledge-based teaching has always been the main theme of school education.The curriculum reform implemented in 2004 has made some achievements,but in order to adapt to the new situation of talent training needs to be improved.Cultivating students' core accomplishment is the comprehensive embodiment of students' ability development in the three dimensions of “knowledge and skills”,“process and method”,“emotional attitude and values”,and is the fundamental task of adapting to the rapidly developing society and improving the national quality.Chemistry is a science that studies the composition,structure、properties and changing laws of matter at the microscopic level of atoms and molecules.Macroscopic identification and microscopic analysis is one of the concrete embodiments of the core accomplishment of the chemistry discipline.The construction of students' particle concept is conducive to the formation of students' core accomplishment.It is helpful for students to form the concept of lifelong learning and rigorous and realistic scientific attitude.Based on the existing research literature on microcosmic chemistry literacy,this paper selects the chemistry textbook of junior middle school published by pep edition as the research model,and focuses on the practical research on cultivating junior middle school students' microcosmic literacy.In this paper,the teaching content of junior high school students' microcosmic literacy cultivation is analyzed,and the teaching implementation is studied in depth.The paper is divided into six parts.The first part is the introduction :it introduces the reasons for writing the paper,expounds the research content and significance of the paper,and introduces the research methods.The second part is the literature review,which mainly introduces the literature research status of many domestic scholars on the cultivation of microcosmic literacy.The third part is the definition of related concepts and the connection between new concepts : the definition of “new concept” and the concept of microchemical literacy.The fourth part is the teaching practice and effect analysis of the new concept : it introduces the process of teaching analysis based on the new concept of micro-chemistry learning and the process of teaching implementation based on the particle concept cultivation.Students and teachers were interviewed according to the specific objectives of the research,and then the practical effect was analyzed.The fifth part is the conclusion and reflection.On the basis of the existing research,this study constructs the specific connotation of junior middle school chemical microcosmic and the development levelof junior middle school students' chemical microcosmic through the theory,then analyzes the factors influencing the development level of junior middle school students' chemical microcosmic accomplishment,and finally puts forward the targeted new concept cultivation strategy and practical research.In this study,four parallel students from a middle school in Hainan were selected to conduct a practical exploration.Students' understanding of microscopic chemistry was analyzed through their interaction with teachers in chemistry class and their chemistry tests.However,due to the limitations of my own ability and time,there are still a lot of things worth further study.I will do better with the accumulation of experience. |
