【摘要】：随着网络技术的快速发展,教育科学技术的进步,传统的课堂教学已经不能满足时代的要求,教学模式也在发生改变。微课作为一种新的学习资源形式在国内外迅速发展了起来,伴随着网络学习和移动互联网学习的深入,微课的基本理念、微课的设计以及应用开发逐渐成为了焦点之一。《数据库原理与应用》课程作为计算机专业核心课程之一,学习掌握好数据库技术是非常有必要的。将该课程的部分内容制作成微课供学生们学习,不仅可以辅助课堂教学、改善授课形式,而且方便学生开阔视野,让学生充分利用课外碎片时间进行有效的学习,提高学习效率。因此制作该课程的微课有很强的实用价值。本文依据教育部计算机科学与技术专业规范的相关课程体系内容,结合高等院校计算机相关学科对《数据库原理与应用》课程的教学大纲要求,对课程内容进行了全面的梳理,分析归纳出6个核心知识单元,共28个片段式知识点,进行教学设计和教学方法的研究,设计并实现28个片段式知识点的微课件。本文使用Camtasia studio平台,提供从屏幕录制、视频编辑到视频输出的整套工具,可以很便捷的进行屏幕录制、声音的处理、添加过渡效果、音画同步、标注处理、添加光标效果以及字幕制作、添加项目版权信息、水印等。本文研究的特色主要体现在:(1)结合动画、视频制作等方式,将部分不易理解的知识内容通过动画展现出来,使课程的重难点和疑点容易理解和掌握。(2)例题和环境演示相结合,学生可以根据操作运行的结果,分析多种SQL操作命令实现方法的差异。(3)利用拍摄后期通过录音将PPT知识点和演算过程连接起来,能够最大限度的理解掌握知识。(4)加入练习题模块,教师可以根据解答情况了解学生掌握程度。(5)微课件作品视频画面清晰,声音和画面协调,知识划分合理,在短时间内能够讲解清楚。这组微课件在某种程度上能够激发学生们的学习兴趣,对于学生理解和深化数据库知识有辅助作用,可以有效提高学生的学习效率。对学生的自主学习能力具有辅助作用。
[Abstract]:With the rapid development of network technology and the progress of educational science and technology, the traditional classroom teaching has been unable to meet the requirements of the times, and the teaching mode is also changing.As a new form of learning resources, micro-lesson has developed rapidly at home and abroad. With the deepening of network learning and mobile Internet learning, the basic concept of micro-lesson is introduced.As one of the core courses of computer major, it is necessary to learn and master database technology well.Making part of the course into a micro-course for students to learn can not only assist in classroom teaching, improve the teaching form, but also facilitate students to broaden their horizons and make full use of extracurricular fragments for effective learning.Improve learning efficiency.Therefore, it is of great practical value to make the micro course of this course.According to the relevant curriculum system of computer science and technology specialty of the Ministry of Education and the requirements of the syllabus of Database principles and applications, this paper makes a comprehensive combing of the course contents, which are related to computer science and technology in colleges and universities, in accordance with the requirements of the syllabus of "Database principles and applications".Six core knowledge units with 28 fragment knowledge points were analyzed and summarized. The teaching design and teaching method were studied. The microcourseware of 28 fragment knowledge points was designed and realized.This article uses the Camtasia studio platform, provides from the screen recording, the video editing to the video output complete set of tools, may very conveniently carries on the screen recording, the sound processing, the addition transition effect, the sound picture synchronization, the annotation processing,Add cursor effect and subtitle making, add item copyright information, watermark and so on.Be able to understand and master knowledge to the maximum extent. 4) add exercise module, teachers can understand students' mastery level according to the solution situation.) Video picture of micro courseware works is clear, sound and picture coordinate, knowledge division is reasonable,Be able to explain clearly in a short time.To a certain extent, this group of micro-courseware can stimulate the students' interest in learning, can help students to understand and deepen the knowledge of database, and can effectively improve the learning efficiency of students.It is helpful to students' autonomous learning ability.
