【摘要】：计算思维对信息时代的科技创新和人才创新至关重要,中小学信息技术课堂是计算思维培养的主要落脚点。但是,当前的课堂侧重于技术工具的学习,不利于学生计算思维的发展。可视化编程工具的出现,为计算思维的培养转变提供了新的契机。基于可视化编程的计算思维培养模式,将项目问题的逻辑组织从拆解转变为叠加,并配合教案的引导与学案的支持,可关注到每个学生的思维发展。运用可视化编程工具App Inventor开展该模式的教学实践,实验结果初步显示:学生的计算思维在计算概念水平上整体得到有效提升,在问题解决的形式化和模型化上的改变,也表现明显。该模式的提出和实验验证,可为进一步在中小学信息技术课堂中研究利用可视化编程,培养学生计算思维,提供有效的实践指导。
[Abstract]:Computing thinking is very important to the innovation of science and technology and the innovation of talents in the information age. The information technology classroom in primary and secondary schools is the main foothold of the cultivation of computing thinking. However, the current classroom focuses on the learning of technical tools, which is not conducive to the development of students' computational thinking. The appearance of visual programming tools provides a new opportunity for the cultivation and transformation of computational thinking. Based on the model of visual programming, the logical organization of project problem is changed from disassembly to superposition, and with the guidance of teaching plan and the support of study plan, the development of thinking of every student can be paid attention to. Using the visual programming tool App Inventor to carry out the teaching practice of this model, the experimental results show that the students' computational thinking has been improved effectively at the level of computing concepts, and the formalization and modeling of problem solving have been changed. The performance is also obvious. The proposed model and the experimental verification can provide effective practical guidance for further research and use of visual programming in the information technology classroom of primary and secondary schools, to cultivate students' computational thinking and to provide effective practical guidance.
