Programming in the wild: trends in youth computational participation in the online scratch community

ABSTRACT

Most research in primary and secondary computing education has focused on understanding learners within formal classroom communities, leaving aside the growing number of promising informal online programming communities where young learners contribute, comment, and collaborate on programs. In this paper, we examined trends in computational participation in Scratch, an online community with over 1 million registered youth designers primarily 11-18 years of age. Drawing on a random sample of 5,000 youth programmers and their activities over three months in early 2012, we examined the quantity of programming concepts used in projects in relation to level of participation, gender, and account age of Scratch programmers. Latent class analyses revealed four unique groups of programmers. While there was no significant link between level of online participation, ranging from low to high, and level of programming sophistication, the exception was a small group of highly engaged users who were most likely to use more complex programming concepts. Groups who only used few of the more sophisticated programming concepts, such as Booleans, variables and operators, were identified as Scratch users new to the site and girls. In the discussion we address the challenges of analyzing young learners' programming in informal online communities and opportunities for designing more equitable computational participation.
