Impact on learning, teaching, and education Since the beginning of the 1980s, and until recently, educational applications of AI have mainly focused on the knowledge-based approach. 61 The most prominent line of research has been concerned with intelligent tutoring systems, or ITS. 62 These systems use a knowledge-based architecture. A typical ITS architecture has a domain model that describes the area to be learned and a student model that describes the current state of student's knowledge and learning. An expert system or pedagogical model manages the introduction of learning materials to the student through an adaptive and interactive user interface. These systems have traditionally used the knowledge-based approach, now commonly known as "gofai" (good-old-fashioned-AI). They have been successful mainly in relatively limited and unambiguous domains, such as mathematics and physics. 63 As student behaviour and learning can also be monitored in ITS environments in great detail, intelligent tutoring environments have also been an important source of data for research on learning. 64 The difficulty in developing ITS for broad learning domains has also switched the focus to the more narrow problem of using AI and machine learning to generate teacher interfaces for student and learning monitoring, and learning diagnostics. This is commonly known as learning analytics and educational data mining (EDM). 65 3.1 Current developments In special needs education, AI-based approaches have shown potential, for example, in the early detection of dyslexia. 66 A well-published example is the Swedish company “Lexplore” that has developed a system that quickly scans for students at risk and detects dyslexia by tracking reader eye movements. The system uses data-based pattern recognition, and the company is now expanding to the US and UK, offering school and school-district wide scanning. 67 AI-based systems have also been successfully developed for the diagnosis of autism spectrum disorder and attention deficit hyperactivity disorder (ADHD). In particular, child-robot interaction seems to enable new forms of diagnostics and special needs educational applications. 68 As student testing plays an important role in many educational systems, many projects are trying to explore the use of AI for automatic test generation and assessment. Much of this work is aimed at automating summative assessment, with a promise of reducing teacher workloads. A possible unintended consequence of this work is that high-stakes testing will be increasingly displaced by frequent low-stakes formative assessment, as the effort and cost required for assessment decreases. Current AI systems are very good in combining evidence from complex and varied sources of data and using them for real- time pattern recognition. For example, student homework can relatively easily be checked and diagnosed by an AI system that has data on both individual student history and peer responses. Accumulated formative assessments could, therefore, to a large extent make high-stakes testing redundant. AI is also beginning to be used to diagnose student attention, emotion, and conversation dynamics in computer-supported learning 61 For an early example, see Sleeman and Brown (1982). 62 E.g., Woolf (2009). 63 E.g. Ritter et al. (2007), Graesser et al. (2005). 64 E.g., Porayska-Pomsta (2015). 65 For a compact review of some relatively recent developments, see Luckin et al. (2016) and a JRC report on Learning Analytics by Ferguson et al. (2016) 66 See, e.g., Drigas and Ioannidou (2012). 67 Jakobsson (2017). For English version, see http://www.lexplore.com/ 68 E.g., Scassellati (2012), Boccanfuso et al. (2016). 28 environments, for example for course development and management, in an attempt to generate optimal groups for collaborative learning tasks, and to recognize patterns that predict student drop-out. 69 To do this effectively, large datasets are needed for training the systems. As was pointed out above, this is a major technical bottleneck. Student behavior also has to be actively monitored to provide feedback for learning. This creates technical needs to unobtrusively monitor students, for example, using video processing and remote eye tracking, with associated ethical and regulatory challenges. Ethically less problematic are systems that use less granular data to provide recommendations. For example, at UC Berkeley students can now get course recommendations using a system that relies on neural AI technologies originally developed for natural language processing and machine translation. 70 Download 1.26 Mb.
