| With the continuous integration of information technology and subject teaching,micro-course,as an important information teaching resource,has been gradually applied to chemistry teaching in high schools and plays an increasingly important role in improving students' key competence of chemistry.The high school chemical micro-course guided by the key competence of chemistry is not only conducive to improving students' chemical ability,but also more benefit to cultivate the scientific spirit,consciousness of innovation and social responsibility of students.Therefore,it was chosen to carry out the research for the design and practice of chemical micro-course in high school based on the key competence of chemistry.The paper mainly includes the following three parts:(1)The first part of the paper is the introduction of the research background and development theory of micro-course.Through the literature research in the early stage,relevant literature on the development of chemical micro-course at home and abroad was consulted.The concept of key competence of chemistry and its supporting theory were studied.The development status of micro-course at home and abroad was analyzed.(2)It was studied for the design method,implementation principle,development process and main characteristics of chemical micro-course.The general design idea included the task-driven and improvement of key competence of chemistry was implemented as a main clue.(3)Three typical cases of the chemistry micro-course were designed,developed and applied according to the requirements of the cultivation of talented person with key competence of chemistry.The questionnaire survey and teacher interview were conducted,and a good evaluation was obtained.Research shows that the chemical micro-course based on key competence of chemistry can stimulate interest of students in learning process of chemical knowledge and cultivate their cooperative learning and autonomous learning ability by method of creating classroom teaching situation and task-driven.It can not only enrich the research on the key competence of chemistry,but also provide a new research perspective for the subsequent design and development of chemical micro-course. |
