本文介绍了一项为期两年的定性研究的结果,研究整合计算机科学(CS)和计算思维(CT)到小学数学教学。综合单位开发的小学教师和CS/CT教练与CS/CT和小学数学专业知识的大学教师的支持。CS/CT教学主要依赖于Scratch环境,尽管有些课程使用了Code.org材料。这项研究主要依赖于两种整合理论(即Kiray,2012年。科学与数学整合的新模式:平衡模式。能源教育科学与技术第B部分:社会与教育研究,4(3),1181-1196),它提供了对学科之间相互联系水平和每个学科内花费的相对教学时间量的洞察。研究结果显示,跨年级CS/CT概念包括排序,循环和条件逻辑。在每个类别中:(a)各年级的概念教学越来越复杂,(B)数学占主导地位,CS/CT很重要,但处于次要地位,(c)出现了三种类型的课程:不整合,部分整合和完全整合。最后,经验教训一般包括从综合程度较低的活动过渡到综合程度较高的活动,在综合活动之前,首先侧重于对具体学科的概念理解。
This paper presents findings from a two-year qualitative study examining integration of computer science (CS) and computational thinking (CT) into elementary mathematics instruction. Integrated units were developed by elementary teachers and CS/CT coaches with support from university faculty with expertise in CS/CT and elementary mathematics. CS/CT instruction primarily relied on the Scratch environment, although some lessons made use of Code.org materials. This research primarily relied on two theories of integration (i.e. Kiray, 2012. A new model for the integration of science and mathematics: The balance model.Energy Education Science and Technology Part B: Social and Educational Studies,4(3), 1181–1196) that provided insight into the level of interconnection between the disciplines and the relative amount of instructional time spent within each discipline. Findings revealed that cross-grade CS/CT concepts included sequencing, looping, and conditional logic. Within each category: (a) concepts were taught with increasing complexity across the grades, (b) the mathematics was dominant and CS/CT was important but secondary, and (c) three types of lessons emerged: No integration, partial integration, and full integration. Lastly, lessons generally included a transition from less integrated to more integrated activities with an initial focus on discipline-specific conceptual understanding prior to integrated activities.
