Research On The Instructional Design Of Biology Teaching In Middle School Under The Micro-class Model

With the rapid development of modern technology,people’s daily life was affected by Wechat,micro-blog,micro-film,which were famous for its "tiny".In the field of Education, Micro lesson was the product of modern education technology and traditional education ideas.The "micro lesson" had the characteristic of "short, small, fine, tough", which showed teaching content integrally and smoothly by the short video. The development of micro video has promoted the reform and development of Education.The rise of micro video helped the innovation and development of education to a center extened.It also boosting personalized learning the construction of digital learning resouse moden conversion. This was an innovative attempt of school teaching mode. Similarly, It was a great exploration of information technology in the biology class. Junior middle school students focus on time is short, and vulnerable to outside interference, new things can often arouse their interest in learning, the characteristics of the micro imposed its visibility and to hear, to help students to quickly enter the learning state.At present, the research on micro-lesson focuses on the theory of research method, micro class mode of production, research and development, etc. The purpose of relevant researchers design of class in order to complete the teaching mission.Or, In the competition.while ignored the study content, learner characteristics and practical characteristics. Recently years, Some teachers had wrong understanding about the micro-class. For example, Before the production of micro class,some teachers hadn’t carry out systematic and comprehensive teaching design, Or Take micro-class as apart of the micro teaching design. Most of teaching design lack comprehensive evaluation criteria and reflection of teaching design.Through the practical investigation, According to the characteristics of the biological teaching and curriculum, The author carry out the research about micro-lesson. Based on the analysis of Junior high school biology learning characteristics and design principle of the micro class. Put forward the specific design of micro lesson and make it into practical teaching. For to explore the reasonable teaching model for micro Junior high school.First of all, This article mainly from the research background, research significance, present situation and the research train of thought four aspects. Provide certain theoretical support for the study of the paper. Review the related literatures, Summarizing predecessors’ experience in teaching, Combined with micro biological micro class teaching design and analysis of the characteristics. Thus, summarizes the key words of biological micro lesson, teaching design, the design of micro teaching in the article. And sums up the theoretical basis of this study. Including constructivism theory, the principle of programmed instruction, education communication theory, etc.On the basis of theory, Combined with the actual teaching situation, Analysis the feasibility of the introduction of micro teaching in the traditional classroom. And try to design and develop the biology micro curriculum in middle school. Then, Describe the innovation of this paper. In this part, And to the design of micro lessons for the development and production. Establish the biological micro class design dimensions. Put forward the specific design scheme of micro lesson, Select two classes of the Foreign Language School Affiliated to Guangxi Normal University. By analyzing the data results, Eavaluated the application effect of micro lesson in biology teaching in middle school. By experiment method, And carried on the experiment research and the result analysis, Obtains the conclusions that under the system theory the micro lesson was obviously superior to the traditional lesson.In the biological sciences, It is necessary to implement micro lesson in traditional classroom. Probe into its with the aid of the progress of science and technology for discipline construction and development, transformate the Concept, Break through the existing bottleneck, To realize a qualitative leap biology course.In the end, Put forward some suggestions of this study and reflect on the disadvantages existing in the research.
