Offline learning in focus as energy crisis looms

The prospect of power cuts and major energy saving measures this winter highlights the need for digital resilience and offering alternative access to educational resources. Up till now we have simply assumed that electricity and internet access were ubiquitous and unlimited, at least in privileged economies. One lesson of the pandemic was that many students did not have unlimited connectivity. Some were learning on pay-as-you-go mobile subscriptions and couldn't afford to watch heavy video files or attend long Zoom sessions. As a result many educators have learnt to offer alternative low-bandwidth formats such as text versions of videos, podcasts and downloadable files and these will be vital if the threats of power cuts come true this winter.

James Clay covers this in a post called When everything goes dark. Low-bandwidth formats are not simply emergency solutions but also smart solutions that offer greater accessibility even when all the lights are on. 

When the power goes out, this means no lights, no power, potentially no heating and no broadband. Of course a blackout also means as well no mobile signal, so no 4G. So though you may have a mobile device with enough battery power to use it, it you won’t be able to use the internet.

Universities should already be planning to provide digital resources that are available offline. He suggests contingency training for teachers on how to offer alternative formats and provide support for students. Even if the crisis is avoided these measures will be not be wasted. A lot of video content can and should be replaced by audio, especially when it is simply 30 minutes of talking head video, and a text version is essential for those who have difficulty hearing the speaker.

If you’re not using video, you don’t have to be constrained by text, downloaded audio recordings and podcasts are possible options. Audio also means that the screen can be turned off (or turn the brightness down) again increasing battery life.

Of course this situation is a typical first world problem. In many parts of the world power cuts and poor connectivity are simply part of everyday life and so work and study need to be adapted round the blackouts. We can learn a lot about resilience from all the educators and students in countries afflicted by crises and war. Many Ukrainian universities have managed to continue their courses in spite of horrific destruction. I don't mean that we have to prepare for such extremes but we certainly need to have alternative strategies ready for implementation when needed. Maybe it's time to reach out and learn from them about how to provide education in times of shortage and crisis.

The end of the essay?

Will artificial intelligence kill off the essay as an assessment form? That seems very likely after reading an article from the University of Sydney, Assessment and integrity in the age of essay-writing artificial intelligence. It describes how you can generate a plausible and well-argued essay on just about any topic using AI algorithms without any risk of falling foul of anti-plagiarism software. The text will be original and offer a variety of perspectives gathered from analysis of countless related texts on the net. In many cases these essays are far better than many students could ever write themselves and the technology is developing rapidly. Similarly the use of AI in teaching is progressing rapidly and we face the prospect of robots teaching and assessing robots.

The most remarkable aspect of this article is that it was written by an AI application called GPT-3 with some minor human edits. It analyses the arguments for and against AI in education and gives examples of how AI generated texts could be used in a positive manner: for example, letting AI generate a text on an introductory paragraph and asking students to compare the AI text with the original. It is remarkably insightful on its own limitations and how academics need to rethink traditional practices to counter the threat of AI.

Because artificial intelligence is trained on a huge corpus of text and has access to the entire internet, it excels at writing and responding to textual prompts. This includes topics that would otherwise be perceived as meeting criteria for authentic assessment. This presents a challenge for higher education academics because we are so accustomed to using exams and other assessments that focus on student knowledge. If artificial intelligence can write essays and answer exam questions, higher education academics need to radically rethink learning, teaching, and assessment in the post-machine era.

But the question remains of whether the essay is a valid form of academic assessment and what new methods we should turn to. The gut reaction to the problem could be doubling down on traditional proctored exam hall tests with no access to digital devices or textbooks but I hope we can think further than this. Learning to write a well argued essay or article is a fundamental skill in all forms of science and it is hard to imagine higher education without this crucial element. But if we can instantly generate an acceptable imitation the exercise becomes somewhat futile. Problem and project-based learning as well as a greater focus on interviews and live seminar discussions would seem to be more relevant both in terms of assessment and as training for professional practice. Writing and critical thinking skills must be learned and practiced but somehow we need new ways to use them. There are already examples of AI-generated texts getting accepted for journal publication and as conference submissions. The foundations of academia are under threat and we need to develop new strategies and methods. 

Jon Dron writes about this in a post, So, this is a thing… and sees the answer in a refocus on people and genuine interaction.

This is a wake-up call. Soon, if not already, most of the training data for the AIs will be generated by AIs. Unchecked, the result is going to be a set of ever-worse copies of copies, that become what the next generation consumes and learns from, in a vicious spiral that leaves us at best stagnant, at worst something akin to the Eloi in H.G. Wells’s Time Machine. If we don’t want this to happen then it is time for educators to reclaim, to celebrate, and (perhaps a little) to reinvent our humanity. We need, more and more, to think of education as a process of learning to be, not of learning to do, except insofar as the doing contributes to our being. It’s about people, learning to be people, in the presence of and through interaction with other people. It’s about creativity, compassion, and meaning, not the achievement of outcomes a machine could replicate with ease. I think it should always have been this way.

Another article, Will artificial intelligence be able to write my college essay? by Eamon Costello and Mark Brown, Dublin City University, raises the need to rethink how we assess learning rather than finding ways to defend the traditional essay. 

Do we try to tame AI to protect old ways of learning or should we embrace its potential and reimagine our assessment practices to reflect the modern reality of living in the 21st century? One creative educator had his students purposefully use and evaluate AI essay writers as part of their assignment.

Finally, this perspective is echoed by the AI-generated article itself, showing a surprising level of insight on its own limitations.

In particular, there is a need to focus on developing higher-order thinking skills such as creativity, critical thinking, and problem-solving, which are not easily replicated by machines. Additionally, it will be important to create opportunities for students to interact with each other and with their instructors on a regular basis, in order to promote the social and emotional skills that are essential for success in the workplace.
