校本课程作为国家课程和地方课程之余的补充课程，能够增强地方、学校和学生的 适应性，为尊重和满足地方、学校和学生的差异性创造条件，校本课程开发已然成为学 校的核心竞争力之一。近几年微课在国内兴起，对微课的理论和实践研究不断涌现，大 量中小学都在进行微课在各学科教学应用的尝试。将微课作为校本课程的新载体，实现 比赛型校本课程的开发，是本研究的主要内容。 本研究是在贵州省实验中学有组织学生参赛的需求，而当下信息技术课程无法满足的背景之下进行的《电脑艺术设计》校本微课程的设计开发。本研究采用准实验研究法，将2019 期学习小组作为实验组，选取 2017 期学习小组作为对照组，以探究校本课程微课化的应用价值。通过对学校教师的访谈和对相关比赛规程的分析，作者以《电脑艺术设计》课程为实践蓝本，分析了课程的特征、课程的需求，进行了学习者分析，借鉴了多位学者的研究结果，采用了“微课程-主题微活动-微课资源包”的模式，参考了马秀麟微课资源包的结构模型，对课程进行了微课化。课程最终采用 CCtalk+微信双平台模式进行呈现，分为操作和实践两大部分，多个主题微活动组成。研究表明，本项目校本课程的微课化，帮助实现了学生作品质量的提升，实现了参赛人数的零突破。 本研究最终形成了包括《电脑艺术设计》校本微课程群和较为稳定的比赛型校本课程微课化模式在内的研究成果。研究成果在贵州省实验中学进行实践应用，为该校学生的相关比赛提供课程服务。 研究发现：将微课作为校本课程开发的新载体，是有效补充校本课程实践中时间和师资受限等方面问题的有效手段。针对课程特征、学习者特征专门设计的完善的微课程环节，，功能齐全的课程平台，都是保障课程目标得以良好实现的前提。在不同的阶段设置不同难度系数的课程，使用不同的管理模式和课程策略，提供多层次、多视角的微课资源，对于学生的自主学习效率提升有积极的作用。

School-bas ed curriculum, as a supplementary curriculum bes ides national curriculum and local curriculum, can enhance the adaptabilit y of local, s chool and s tudents, and create conditions for respecting and meeting the differences between local, school and students. S chool -based curricu lum development remains one of the core competitiveness of schools . In recent years, micro- less ons have s prung up in China, and the theoretical and practical res earch on micro- less ons has been constantly emerging. A large number of primary and secondary s c hools are tr ying to apply micro- less ons in various dis ciplines. The main content of this s tudy is to take micro - cours e as a new carrier of school - bas ed curriculum and realize the development of competition- bas ed s chool-based curriculum. This research is to des ign and develop the school- bas ed micro- curriculum of Computer Ar t Des ign under the background that the information technology curriculum can not meet the needs of organiz ed students in Guiz hou experimental middle s chools. In this stud y, quas i-experimental research method was used to explore the application value of s chool-based curriculum microteaching. The study group of 2019 was selected as the experimental group, and the study group of 2017 was selected as the control group. Through interviews with s chool teachers and analys is of relevant competition rules, the author takes the course of Computer Art Design as a practical blueprint, analys es the characteris tics of the course and the needs of the cours e, carries out learner analys is, draws on the res ea rch results of many scholars, adopts the mode of "micro - curriculum- thematic micro- activit y-micro- curriculum res ource package", and refers to the structure model of Ma X iulin's micro - curriculum res ource package type ，thecurriculum has been micro-class ified. F inally, the course is pres ented by CCtalk + Wechat dual platform model, which is divided into tw o parts : operation and practice, and cons is ts of several thematic micro -activit ies. The research s hows that the micro- teaching of school- bas ed curriculum in this project helps to improve the qualit y of students ' w orks and achieve zero breakthroughs in the number of participants. The research results include the school - based micro- curriculum group of Computer Ar t D esign and the more s table competition -based mic ro-curriculum model. The res earch results are applied in Guiz hou experimental middle school to provide curriculum services for the relevant competitions of students in Guiz hou experimental middle school. The research finds that micro- less ons as a new carrier of s chool-based curriculum development is an effective means to effectively supplement the time and teacher cons traints in school - bas ed curriculum practice. The perfect micro- curriculum links s pecially des igned for the characteristics of curriculum and learners, as w ell as the fully functional curriculum platform, are the prerequis ites to ensure the good realization of curriculum objectives . Setting up courses w ith different difficulty coefficients at different s tages, us ing different management models a nd curriculum s trategies, and providing multi- level and multi-perspective micro -course res ources, w ill play a pos itive role in improving students' self- learning efficiency.
