What is an algorithm?

September 3rd, 2018 by Graham Attwell

There was an excellent article by Andrew Smith in the Guardian newspaper last week. ‘Franken-algorithms: the deadly consequences of unpredictable code’, examines issues with our “our new algorithmic reality and the “growing conjecture that current programming methods are no longer fit for purpose given the size, complexity and interdependency of the algorithmic systems we increasingly rely on.” “Between the “dumb” fixed algorithms and true AI lies the problematic halfway house we’ve already entered with scarcely a thought and almost no debate, much less agreement as to aims, ethics, safety, best practice”, Smith says.

I was particularly interested in the changing understandings of what an algorithm is.

In the original understanding of an algorithm, says Andrew Smith, “an algorithm is a small, simple thing; a rule used to automate the treatment of a piece of data. If a happens, then do b; if not, then do c. This is the “if/then/else” logic of classical computing. If a user claims to be 18, allow them into the website; if not, print “Sorry, you must be 18 to enter”. At core, computer programs are bundles of such algorithms.” However, “Recent years have seen a more portentous and ambiguous meaning emerge, with the word “algorithm” taken to mean any large, complex decision-making software system; any means of taking an array of input – of data – and assessing it quickly, according to a given set of criteria (or “rules”).”

And this, of course is a problem, especially where algorithms, even if published, are not in the least transparent and with machine learning, constantly evolving.

    Open Educational Resources

    BYU researcher John Hilton has published a new study on OER, student efficacy, and user perceptions – a synthesis of research published between 2015 and 2018. Looking at sixteen efficacy and twenty perception studies involving over 120,000 students or faculty, the study’s results suggest that students achieve the same or better learning outcomes when using OER while saving a significant amount of money, and that the majority of faculty and students who’ve used OER had a positive experience and would do so again.


    Digital Literacy

    A National Survey fin Wales in 2017-18 showed that 15% of adults (aged 16 and over) in Wales do not regularly use the internet. However, this figure is much higher (26%) amongst people with a limiting long-standing illness, disability or infirmity.

    A new Welsh Government programme has been launched which will work with organisations across Wales, in order to help people increase their confidence using digital technology, with the aim of helping them improve and manage their health and well-being.

    Digital Communities Wales: Digital Confidence, Health and Well-being, follows on from the initial Digital Communities Wales (DCW) programme which enabled 62,500 people to reap the benefits of going online in the last two years.

    Zero Hours Contracts

    Figures from the UK Higher Education Statistics Agency show that in total almost 11,500 people – both academics and support staff – working in universities on a standard basis were on a zero-hours contract in 2017-18, out of a total staff head count of about 430,000, reports the Times Higher Education.  Zero-hours contract means the employer is not obliged to provide any minimum working hours

    Separate figures that only look at the number of people who are employed on “atypical” academic contracts (such as people working on projects) show that 23 per cent of them, or just over 16,000, had a zero-hours contract.


    Resistance decreases over time

    Interesting research on student centered learning and student buy in, as picked up by an article in Inside Higher Ed. A new study published in PLOS ONE, called “Knowing Is Half the Battle: Assessments of Both Student Perception and Performance Are Necessary to Successfully Evaluate Curricular Transformation finds that student resistance to curriculum innovation decreases over time as it becomes the institutional norm, and that students increasingly link active learning to their learning gains over time
