It’s all very well getting an AI to write your code for you but neither writing code or reading code are the same as understanding code. So what is going on in novices brains when they learn to actually understand the code they are reading and writing? Join us on Monday 6th March at 2pm GMT to discuss a paper by Quintin Cutts and Maria Kallia from the University of Glasgow on this very topic [1], from the abstract:

An approach to code comprehension in an introductory programming class is presented, drawing on the Text Surface, Functional and Machine aspects of Schulte’s Block Model, and emphasising programming as a modelling activity involving problem and machine domains. To visually connect the domains and a program, a key diagram conceptualising the three aspects lies at the approach’s heart, alongside instructional exposition and exercises, which are all presented. Students find the approach challenging initially, but most recognise its value later, and identify, unexpectedly, the value of the approach for problem decomposition, planning and coding.

We’ll be joined by one of the co-authors (Quintin Cutts), who’ll give us a lightning talk summary of the paper to kick-off our journal club discussion. [1] Quintin has added: “You can’t write if you can’t read.  In just four pages the paper outlines a classroom approach to developing in novices good code comprehension right from the start of an introductory course.  There’s also some feedback on what students thought, a year later – spoiler – they seemed to get a lot from it.  Anyone teaching introductory programming might find such a short paper thought provoking, even if they don’t pick up the technique in their teaching. Worth a quick read, and coming along to listen/add to the discussion…”

All welcome, as usual we’ll be meeting on zoom, details at sigcse.cs.manchester.ac.uk/join-us.

Computing is too important to be left to men, but where have all the women gone? While women continue to play a key role in computing they are currently under-represented in Computer Science. How can we change this and what evidence is there for practices that get more women into computing? Join us to discuss the subject via a paper by Briana Morrison et al [1] on Monday 7th February at 2pm GMT. Here is the abstract of the paper:

Computing has, for many years, been one of the least demographically diverse STEM fields, particularly in terms of women’s participation. The last decade has seen a proliferation of research exploring new teaching techniques and their effect on the retention of students who have historically been excluded from computing. This research suggests interventions and practices that can affect the inclusiveness of the computer science classroom and potentially improve learning outcomes for all students. But research needs to be translated into practice, and practices need to be taken up in real classrooms. The current paper reports on the results of a focused systematic “state-of-the-art” review of recent empirical studies of teaching practices that have some explicit test of the impact on women in computing. Using the NCWIT Engagement Practices Framework as a means of organisation, we summarise this research, outline the practices that have the most empirical support, and suggest where additional research is needed.

All welcome, whatever your gender identity, gender expression or biological sex. As usual we’ll be meeting on zoom, details are in the slack channel sigcse.cs.manchester.ac.uk/join-us

It’s no secret that both Computer Science and engineering have inequalities in their participation. Join us to re-examine and discuss these inequalities via a paper by Maria Kallia and Quintin Cutts [1] on Monday 4th October at 2pm BST. This won a best paper award at ICER 2021. From the abstract:

Concerns about participation in computer science at all levels of education continue to rise, despite the substantial efforts of research, policy, and world-wide education initiatives. In this paper, which is guided by a systematic literature review, we investigate the issue of inequalities in participation by bringing a theoretical lens from the sociology of education, and particularly, Bourdieu’s theory of social reproduction. By paying particular attention to Bourdieu’s theorising of capital, habitus, and field, we first establish an alignment between Bourdieu’s theory and what is known about inequalities in computer science (CS) participation; we demonstrate how the factors affecting participation constitute capital forms that individuals possess to leverage within the computer science field, while students’ views and dispositions towards computer science and scientists are rooted in their habitus which influences their successful assimilation in computer science fields. Subsequently, by projecting the issue of inequalities in CS participation to Bourdieu’s sociological theorisations, we explain that because most interventions do not consider the issue holistically and not in formal education settings, the reported benefits do not continue in the long-term which reproduces the problem. Most interventions have indeed contributed significantly to the issue, but they have either focused on developing some aspects of computer science capital or on designing activities that, although inclusive in terms of their content and context, attempt to re-construct students’ habitus to “fit” in the already “pathologized” computer science fields. Therefore, we argue that to contribute significantly to the equity and participation issue in computer science, research and interventions should focus on restructuring the computer science field and the rules of participation, as well as on building holistically students’ computer science capital and habitus within computer science fields.
