High School Chemistry Teaching Design Based On Key Competencies Of Chemistry

With the development of economy,science and technology,the society has entered a new stage of development which makes greater demands for talents.Based on this situation,the Ministry of Education issued the opinions on Deeping Curriculum Reform and Implementing the Fundamental Tasks of the Lide Tree,which put forward "moral education" concept,making the new curriculum reform get to a new teaching mode that aims at nurturing students' core qualities.Chemistry,as an indispensable part of high school education,must assume its "hundred-year-old tree" responsibility.As a result,how to cultivate and improve students' chemistry literacy becomes an indispensable proposition for us to research and practice new teaching methods in chemistry classroom teaching.In summary,the new curriculum reform implementation plan is an event that requires a lot of research scholars in the chemical sciences core qualities to do further research and to improve the standard of the new curriculum reform;the need for teachers to research on how to set up a reasonable scenario,how to guide students to think on new knowledge,and how to make the illustrations of chemical core concepts more logical,and how to make classroom teaching evaluation more effective,becomes significant,which requires a lengthy study process to complete and perfect,but we must believe that in the near future,these studies will be able to add new vitality to quality education and core literacy training of chemistry.The study involves a variety of methods.Firstly,literature review is used to study previous researches done by domestic and foreign scholars in recent years on key competencies of Chemistry,which is also used as the basis and rationale for thisissue.Secondly,I use interviews.I study the effects of adopting teaching design based on the core literacy of students by observing and analyzing students' behaviors in the classroom,individual conversations,questionnaires,and observing students' performance and mood changes.Then I use case study.Taking aluminum and its compounds,chemical energy and electrical energy,galvanic cells,and redox reactions as examples,more real life pictures and videos are used to stimulate students' interest in learning chemistry,and construct scenes in which students can establish the network of knowledge automatically,in order to study and practice how to maximize the achievements of classroom teaching by cultivating students' chemical core literacy and find more efficient ways of teaching.At the same time,I use classroom observation,observing students' specific behaviors especially the degree of participation in teaching-learning process...and finally,teaching,learning and assessment are integrated to evaluate students.More attention is drawn to the guidance and cultivating of students' individual thinking.After the research,I find high school chemistry teaching has the following problems: 1.Students gradually lose interest in the chemistry study during the learning process.2.Teachers still concentrate on traditional indoctrinated way of teaching,while the new teaching mode is seldom used.3.For various reasons,classroom labs are rarely adopted.This article analyzes these problems,and gives a conclusion: to guide students on self-learning,and group learning.The core concepts in chemistry learning should be illustrated logically and the systematically by classifying and refining,which will contribute to cultivating students' enthusiasm and dedication of learning;by situational teaching and connecting chemistry problems with real-life experience,students can form logical thinking both macroscopically and microscopically besides some other chemical thinking methods,and this allows students to have a more serious scientific attitude and greater social responsibility;The new evaluating approach integrating teaching,learning and assessment can help students change their ways of studying Chemistry,and better develop their spirit of innovation.
