【摘要】：随着“互联网+”行动计划的提出,信息技术与学科教学深度融合已成为现实发展需求。微课以其“短小精悍”的特点契合了网络时代的个性化学习、碎片化学习、移动学习等需求,成为教育教学改革的切入点之一。如何设计、制作及应用与评价微课,是教师需要掌握的新技能。梳理近年来研究微课的文献发现:国内微课研究发展呈上升趋势,但对微课研究的系统性不足,基于化学学科特色和知识类型的系列微课开发和评价体系研究成果鲜见。本研究以“国培计划”(2016)初中化学班学员的26个微课作品为研究对象,统计分析发现:大多数作品(1)选题指向明确,能够围绕重点、难点展开;(2)内容逻辑基本清晰,注重渗透学科思想和资源完备性;(3)制作技术基本达标,解说旁白有待提升。通过对不同知识类型的代表性微课作品进行课例分析,本研究建议:微课优化设计者在满足微课的“微”和符合学生学习需求基础之上,还必须把控好三个关键环节:(1)选题,好选题是优秀微课作品的价值前提;(2)教学设计,实效性教学设计是优秀微课作品的关键;(3)脚本设计,(分镜头)脚本设计是优秀微课作品的制作基础。
[Abstract]:With the development of the action plan of "Internet", the integration of information technology and subject teaching has become the demand of the development of reality. With its "short and intrepid" characteristics, micro-curriculum fits in with the individualized learning in the network age. Fragmented learning, mobile learning and other needs have become one of the breakthrough points of educational reform. How to design, manufacture, application and evaluation of micro-courses. It is a new skill that teachers need to master. Combing the literature of micro-lesson research in recent years, it is found that the development of micro-lesson research in China is on the rise, but the systematicness of micro-lesson research is insufficient. There are few achievements in the development and evaluation system of a series of microcourses based on the characteristics of chemistry and knowledge types. This study focuses on 26 microcourse works of junior high school chemistry students. The statistical analysis shows that: most of the works have a clear choice of topics, can focus on the key, difficult to start; 2) the content logic is basically clear, pay attention to permeate the discipline thought and the resource completeness; 3) the production technology is basically up to standard, and the narration and narration need to be improved. Through the analysis of the representative micro-lesson works of different knowledge types, the course examples are analyzed. This study suggests that on the basis of meeting the needs of students and meeting the needs of students, the designer of microcourse optimization should control three key links: 1). Good topic selection is the value premise of excellent micro-lesson works; 2) Teaching design, practical teaching design is the key of excellent micro-course works; Script design script design is the basis of excellent micro-class works.
