Keynote for V Jornadas Iberoamericanas de Interacción Humano-Computador 2019 http://mexilab.com/V_Jornadas_HCI/#1#schedule Drawing on examples from academic research in the field of artificial intelligence in education (AIED) and learning analytics (LA), I will cut through the current hype and make a case for carefully designed systems for a wide range of pedagogies. As an introduction to the field, the talk will first share how the growing concerns about the role of AI in society, big data and big companies are entering education. Using the case of exploratory learning, I will then offer possible responses challenging designers, developers and educators, to seize the opportunities afforded by the emerging technological context around data, analytics and AI, while carefully considering design choices when it comes to practical implementation.

- Discuss cases where you’ve seen (or can imagine) AI applied in Education
- Terminology clarifications. Not talking about VR/AR (though can be enabled by AI). Or teaching of AI (though that’s important especially these days)
- While anything is possible, not everything is the right thing we should be spending our time
- Popular AI
- So AI is becoming more and more popular through movies and the same applies for data analysis. Movies like ex machine and transcendence may be actually damaging the perceiption of field with their technocentric portayal of AI. When I talk to teachers about AI in education they usually say that we are building Minory Report to predict students failure but I think we aare more closer to Money Ball that revolves around a coach using data and computer analytics to judge and acquire players rather than on mere biases. Showing that is more about asking the right questions than just having the data.
- A vision of AIED 1992 - cyberpunk dystopian victorial times (post AI) Primer is designed to react to the owners environment teach them what they need to know to survive. Something like a Mentor (reference back to Telemachus)
- Lack of agency
- Critique useful but ignores research
- I ‘ll make a case that it is important for these to come together **led** by teaching and learning needs
- The critics claim that the learner has little agency, is forced along a particular, even if individualised, path This gives no opportunity to interact with the system about what is being learned. They are often positioned as well as being possible to replace the teaacher And being the low hanging fruit
- But it is actually the argument that is the low hanging fruit as it weak
- Still particular type of intelligence People learn in other ways too.
- So I mentioned one goal in the field is to design EEL
- I use the term rather loosley
- Whizz through some examples
- 3d logo
- Some of you may know Dynamic geometry
- Domain language model areas Game knows where to place children within the domain model – stores child’s performance in a learner model – adapts content and activity based on this performance
- 41
- messages that approximate (NOT REPLACE!) human behaviour
- To tap into students’ inner thoughts we introduced speech recognition technology
- And what a better application for AI? A complex world of unstractued data to make sense of !
- We address these challenges party with this architercture
- 06:00
- 06:00 perceived task difficulty classifier (PTDC) which uses prosodic cues in the student’s speech to predict the level of challenge for the current student, and the output from speech recognition software which identifies words in the student’s speech.
- 06:00
- his layer contains an affective state reasoner, implemented as a Bayesian network which draws on information from the learner model, in particular the student’s affective state, to decide what type of feedback should be provided to the student. The resulting feedback type is then stored in the learner model and provided to the feedback generation layer.

- I will not go into details here. But
- 25-30 minus here
- Max 30 minutes here
- So all nice but limitations ! AI Singularity is not close - We know there are places where students will get stuck in new ways where AI fails - And when that happens we know that AI will be perceived again as Black Box
- 62
- But this is where my case for better integration of AI and LA comes
- Most often than not the case is as in this cartoon that helps us remember that
- 67
- 68
- And ok we may not be able to give them cloining but we can simualate eyes in back or whether students are
- So I think so far we are only scratching the surface and some of the work that is emerging is quite powerful
- And we designed different types of feedback that could be applied ranging from talk aloud to remind them to talk to targeting their affect to reflective prompts
