摘要

并行和分布式计算(PDC)现在被认为是计算的一个门槛概念,并被嵌入到全球的计算课程中。虽然传统计算集群的成本使开发实践活动变得具有挑战性,但低成本计算机的兴起,特别是树莓派计算机,促使人们探索如何使用树莓派集群向学生教授PDC。在这项工作的基础上,我们报告了我们开发一系列低成本树莓派集群的经验,供远程开放大学学生使用。基于484名学生的调查结果,我们认为我们的工作证明了远程实践活动对PDC概念教学以及吸引学生的好处。最后,我们讨论了两个关键挑战:通过学生主导的集群编程支持主动学习,以及远程支持表现较差的学生。

Passive or active learning: the challenges of teaching distributed computing using Raspberry Pi clusters to open distance university students
Parallel and distributed computing (PDC) is now considered a threshold concept for computing, and is embedded in computing curricula across the globe. While the costs of traditional computing clusters have made developing practical activities challenging, the rise of low-cost computers, particularly the Raspberry Pi, has led to an exploration of how PDC can be taught to students using Raspberry Pi clusters. Building on this work, we report our experiences from developing a series of low-cost Raspberry Pi clusters for use with open distance university students. Based on survey results from 484 students, we argue that our work demonstrates the benefits that remote practical activities can have for teaching PDC concepts, as well as engaging students. We conclude with a discussion of two key challenges: supporting active learning through student-led programming on the clusters, and supporting lower-performing students at a distance.
