Computer programming in schools… Can we avoid coding ourselves into a corner?25 Maj-2017 | Skrivet av i Okategoriserade
The push for Swedish schools to teach students to code computers is now in full swing. This year, the Swedish government announced key changes to its requirements for the teaching of ‘digital competence’ in schools. This shift includes provision for programming to be introduced at all grade levels, becoming “a distinct feature of several different subjects in primary schools, especially in technology and mathematics”.
Sweden is by no means alone in these ambitions. Indeed, countries around the world are rushing to introduce computer programming, coding and software development into the curriculum. Increasing numbers of teachers are being trained to teach computer science in primary and secondary classrooms. Well-funded organizations such as Code.Org and Code the Future are offering outside-school tuition and resources. There has been a surge of interest in low cost mini-computers such as the Micro:Bit and Raspberry Pi, alongside programming languages such as Scratch and Python. Coding has quickly become part of the global educational agenda.
At first glance, it might seem that there is little to disagree with. After all, coding is fun, intellectually challenging and in tune with current educational preoccupations with all things ‘STEM’ (Science, Technology, Engineering and Mathematics). These are skills that one would expect to be important for future employment. Coding also fits neatly with the rising prominence of Silicon Valley thinking and ‘geek culture’. Crucially, coding offers a possible means of addressing the perennial ‘crisis’ of schools failing to meet contemporary economic and societal needs. For all these reasons, most people consider coding in the classroom to be a ‘no brainer’.
Yet as these plans begin to be put into practice, there are signs that things are not quite as straightforward as we might like to think:
- First is the problem of what is actually being taught. There are various flavors and forms of ‘coding’, but the type that is filtering down to many classrooms is a rather bland, generic and simplistic form of engaging with the subject. As one IT industry insider recently observed, many schools are delivering superficial forms of ‘pop computing’, based around “watered down content and using simple coding apps” that only offer “quick experiences of drag-and-drop code entertainment”. Moreover, while there might seem to be much conceptual overlap between programming and other school subjects such as math, there is little empirical evidence for sustained transfer effects between learning programming and other domains. Similarly, as Laura Pappano recently noted, “there is no reliable research showing that computing makes one more creative or more able to problem-solve”. A recently published randomized control trial found that after-school coding clubs in the UK had no impact on computational thinking as measured by the BEBRAS assessment, but did significantly improve coding competency. Thus, concern is growing that the kinds of forms of coding being introduced may have little potential for developing general skills or creating learning transfer to other subjects, and that they may end up eating into the limited time for other core school subjects.
- Second is the problem of how coding is actually being taught. Some ‘new’ computer science subjects have been criticized as narrowly technical and procedural (echoing the distinction that Mike Trucano makes between ‘learning acheter viagra to code’ as opposed to ‘coding to learn’). There are growing reports of teachers and students struggling with coding and programming, particularly in primary schools. Many adults have been shocked to find students getting bored with what they find to be not such a ‘fun’ activity after all. As Mitch Resnick (the MIT professor involved in LOGO and the child-oriented Scratch programming environment) argues, “if you present just logic puzzles, it’s like teaching them writing by only teaching grammar and punctuation.” How ‘best’ to teach coding at scale across entire school systems is a challenging (and as yet unanswered) question that will require considerable time and effort to resolve.
- Third is the problem of securing the scale of funding and resourcing required to match the considerable hype. Achieving system-wide school change takes more than promises and enthusiasm, and policymakers have struggled to commit to coding in schools on a substantial level. Even President Obama’s much-touted promise in 2016 to commit $4billion of federal funding for computer science education in US schools was never realized. Countries such as Sweden need to learn from the mistakes made in countries such as England that drastically underfunded teacher professional development in how to teach new coding curricula. One year after England’s new computing curriculum came into effect in 2014, over 40% of primary teachers reported not having had adequate professional development and nearly one third reported lacking the ability to teach the new subject matter. Governments around the world are finding that rewriting their national curriculum documents is the easy part. Achieving genuine systemic change requires sustained resourcing commitments over long periods of time.
Despite these limitations, the coding bandwagon rolls on relentless. This puts the educational technology community in a bind. On one hand, it is pleasing to see ‘our’ area finally getting some mainstream attention and love. Coding has certainly pushed ‘Ed-Tech’ agendas to the forefront of the popular and political consciousness. On the other hand, there is growing danger that this hype and effort will end up repeating previous Ed-Tech failures and disappointments. This is not the first time that educational technology has enjoyed a brief moment in the limelight, only to be met by practitioner indifference and lack of sustained funding and policy commitments. Anyone familiar with the history of computers in schools can be forgiven for suspecting that this current Ed-Tech ‘moment’ may not end well.
So, what can be done? For us, this is an area of ‘digital education’ that is in urgent need of more open debate and realistic discussion. Most people, ourselves included, are not against the idea of coding being part of schools per se. Yet all the recent developments just outlined have certainly occurred with undue haste and little (or no) critical scrutiny. As such, it seems imperative to reclaim the topic of ‘coding in schools’ as a site of balanced conversation, consideration and choice – moving past the hype and fears that currently surround it.
So what might be done? This is certainly a topic that needs to be better problematized, questioned and productively challenged. There are many different ways that coding might be part of schooling, many different rationales and approaches. One might propose, for example, a completely different version of ‘coding in schools’ that fosters critical understandings of the politics and social power of programming and algorithmic culture. Perhaps, as a recent article in Wired reasoned, coding classes should be seen as a vocational option likely to lead to the twenty-first century equivalent of a skilled job in a car factory, as opposed to a fast track to becoming the next Mark Zuckerberg.
These are all debates that a country such as Sweden needs to be pursuing. It is time that some simple but direct questions are addressed – not least:
Why exactly are we doing this, and what do we want to result?
Most importantly, how might we initiate a more thoughtful, nuanced debate about the pros and cons of what is clearly not a straightforward development? Now the curriculum changes have been finalized, the challenge of coding in schools has only just begun.
