【摘要】：在信息化社会,具有创意计算思维能力是这个社会的需要,是每个人应具备的基本技能之一。而我国对学生的计算思维的培养一般是在大学的计算机基础课堂上,从基本概念开始学习,虽然大学生有一定的学习能力,但是,这样学起来也是感觉枯燥无味,学习效果并不太好,这种培养方式不能满足社会对人才的需要。在信息化高速发展的今天,人人都应具备处理各种信息的能力,而这种能力的培养要从孩子抓起。目前,提高每一位学生的信息素养,已成为中小学信息技术课的培养目标。但是,在具体实施过程中,虽也取得一定的成果,但还是不是很令人满意,因为教授内容主要是计算机基本操作方法和office办公软件的使用,内容不能激起学生学习的兴趣,更别说培养他们处理各种信息的能力了。近几年,一款儿童编程软件走进一线中小学教师的视线,这款软件让老师们眼前一亮,简单易操作的界面,能融合多种媒体形式,加点小创意,就是一部不错的作品。这款软件就是由美国麻省理工大学(MIT)多媒体实验室开发的一款针对儿童的编程软件Scratch。老师们边学边教边研究教学方法,取得了一定的成效,学生们对这个软件也很欢迎。本研究主要通过Scratch儿童编程软件教学的具体实施,辅以具有特色的可视化教学工具来培养小学高年级学生的创意计算思维。本论文内容主要包括以下五个章节:第一章首先通过计算思维和Scratch儿童编程软件这两大当今社会和教育界研究的热点来阐明本研究的问题和意义,以及研究现状,然后明确了本次研究要用的研究方法。第二章主要对计算思维和可视化的概念进行了界定,然后简单介绍了Scratch软件,最后阐述了什么是创意计算思维,以及Scratch与创意计算思维的融合。第三章主要根据创意计算思维包含的算法思维、系统思维和设计思维,再结合Scratch软件的特点进行可视化教学工具的设计,以及过程性评价的设计。第四章是本研究的行动研究过程,包括研究环境、对象和教学内容的分析,研究问题的确立,研究的实施过程和教学改进策略。第五章是对本研究进行总结和展望,概括了本研究的创新点和不足之处,以及对今后Scratch教学研究提出展望。
[Abstract]:In the information society, the ability of creative computing is the need of this society, and it is one of the basic skills that everyone should have. However, in our country, the cultivation of students' computational thinking is generally conducted in the basic computer classroom of a university. They begin to study from the basic concepts. Although college students have a certain degree of learning ability, however, it also feels dull to learn in this way. Learning effect is not very good, this training method can not meet the needs of social talents. With the rapid development of information, everyone should have the ability to deal with all kinds of information, and the cultivation of this ability should start with children. At present, improving the information literacy of every student has become the training goal of information technology course in primary and secondary schools. However, although some achievements have been made in the concrete implementation process, they are not very satisfactory, because the contents of teaching are mainly about the basic operating methods of computers and the use of office software, and the contents cannot arouse students' interest in learning. Not to mention developing their ability to process all kinds of information. In recent years, a child programming software into the line of sight of primary and secondary school teachers, this software lets teachers see a bright, easy to operate interface, can blend a variety of media forms, add a little creative, is a good work. This software is developed by MIT (MIT) Multimedia Lab, a software for children programming Scratch. The teachers studied the teaching methods while learning, and the students welcomed the software. This research mainly through the Scratch children programming software teaching concrete implementation, auxiliary with the characteristic visual teaching tool to train the primary school senior student's creativity computation thought. The content of this thesis mainly includes the following five chapters: the first chapter clarifies the problems and significance of this research and the present situation of the research through computational thinking and Scratch children programming software, which are two hot research topics in the society and educational circles. Then the research methods to be used in this study are defined. In the second chapter, the concepts of computational thinking and visualization are defined, and then the Scratch software is briefly introduced. At last, what is creative computing thinking and the fusion of Scratch and creative computing thinking are expounded. In the third chapter, according to the algorithm thinking, system thinking and design thinking, the visual teaching tools are designed according to the characteristics of Scratch software, and the process evaluation is designed. The fourth chapter is the action research process of this study, including the analysis of the research environment, the object and the teaching content, the establishment of the research problem, the implementation process of the research and the teaching improvement strategy. The fifth chapter summarizes and prospects the research, summarizes the innovative points and shortcomings of this study, and puts forward the prospect of Scratch teaching research in the future.
