Teaching concurrent programming concepts using scratch in primary school: Methodology and evaluation

Abstract

Computer programming can help children develop problem solving and analytical skills. Thus, many countries have included computer science in the curriculum of primary school. Given differences in culture, available infrastructures, as well as the age pupils are introduced to computer science, forming a computer science curriculum still remains a challenge. Towards this end, this study focuses on exploring the potential merits of introducing concurrent programming concepts early in the learning process. The basic premise is that although concurrent programming at its full details is a rather advanced topic even at university level, it is everyday practice to perform two or more tasks simultaneously that might need (or not) some sort of synchronization. Therefore, the tutor can capitalize on everyday experience to explain basic concepts on concurrency. Such correlation between life experience and concurrent programming challenges may expand the cognitive functions of the pupils and provide them with further background to improve analytical thinking. The proposed curriculum for fifth and sixth grade primary school was adopted in seven classes in Greece. Results indicate that uninitiated to programming pupils at the age of ten (fifth grade) were able to comprehend basic concurrency topics, while pupils at the age of eleven (sixth grade) with some programming familiarity were able to understand more advanced concepts. © 2018 Kassel University Press GmbH.
