Under the background of information age, autonomous learning is more and more advocated by people. In order to adapt to the development of the times, a new type of curriculum came into being, this is micro-courses, it is based on the micro video as the core, of which the content is short and the theme is clear, it must be limited 10 minutes, has the characteristics of terse and forceful, good flexibility, meet the requirements of modern people on the way of learning. After being introduced into the field of education, micro curriculum has also been favored by the majority of educators, it focuses on personalized teaching, pay attention to students’ autonomous learning, and it is a better auxiliary form of students’ formal learning. Taking into account the actual situation and the feasibility of the research, this paper choose the junior high school mathematics as a basic point, and selects a part of compensation type micro course after class, trying to explore students’ understanding of this type of micro courses,such micro curriculum design methods and principles.This paper has carried on the discussion and the research on Junior middle school mathematics compensation type micro course after class by using the methods of literature research, interview and questionnaire survey. First, through the research of literature, systematically combing the relevant research status of micro lecture at home and abroad, try to summarize the concept, forms, characteristics and theoretical basis of micro lecture, provide some theoretical support for the study. Through the way of questionnaire survey to understand the students’ online autonomous learning and the preliminary understanding and evaluation of micro course, try to explain the possibility and necessity of the application of micro course .On the basis of the literature research, through the communication with a gleam of mathematics teachers and the questionnaire of students, try to define the after-class compensation type micro course, and give a preliminary classification,including the review of classroom learning fragments, the difficult point of the analytical and comb,easy fault point again,of exploring knowledge to ascend. Then,from the two aspects of topic selection and content design, this paper analyzes the design process of compensation type micro lecture, the author believes that the selection of topic selection should follow the principle of value, pertinence, typicality and compensation.This paper analyzes the design method of curriculum content,mainly analyzes the teaching design of micro lecture. Finally,the author summarizes the unique principles of the content design of micro curriculum:miniaturization principle , learner centered principle, practical principle, interactive principle, the principle of understandability , individualized principle.According to the above for the classification of after-class compensation type micro mathematics curriculum,The author chose two classes of error-prone points of parsing and expand ascending type micro course, and chose a case "solution of fractional equation error prone points" and "equation, inequality and function relations", analyzes the curriculum design process from the topic selection, design ideas, scripts and make several aspects respectively. Through the students watching some micro lecture, using the way of questionnaire to explore the preliminary understanding and overall evaluation of students’ after-class compensation type micro course.The majority of students are able to agree with the design method and method of after-school compensation micro curriculum, and realize its advantages and uniqueness.Finally,the main conclusions of this study are summarized,and the deficiencies in the study and the prospect of follow-up research. |
