The human–computer interaction (HCI) design of educational technologies influences cognitive behaviour, so it is imperative to assess how different HCI strategies support intended behaviour. We developed a neuroscience-inspired game that trains children's use of “stopping-and-thinking” (S&T)—an inhibitory control-related behaviour—in the context of counterintuitive science problems. We tested the efficacy of four HCI features in supporting S&T: (1) a readiness mechanic, (2) motion cues, (3) colour cues, and (4) rewards/penalties. In a randomised eye-tracking trial with 45 7-to-8-year-olds, we found that the readiness mechanic increased S&T duration, that motion and colour cues proved equally effective at promoting S&T, that combining symbolic colour with the readiness mechanic may have a cumulative effect, and that rewards/penalties may have distracted children from S&T. Additionally, S&T duration was related to in-game performance. Our results underscore the importance of interdisciplinary approaches to educational technology research that actively investigates how HCI impacts intended learning behaviours.

This article examines the educational efficacy of a learning environment in which children diagnosed with Autism Spectrum Conditions (ASC) engage in social interactions with an artificially intelligent (AI) virtual agent and where a human practitioner acts in support of the interactions. A multi-site intervention study in schools across the UK was conducted with 29 children with ASC and learning difficulties, aged 4--14 years old. For reasons related to data completeness and amount of exposure to the AI environment, data for 15 children was included in the analysis. The analysis revealed a significant increase in the proportion of social responses made by ASC children to human practitioners. The number of initiations made to human practitioners and to the virtual agent by the ASC children also increased numerically over the course of the sessions. However, due to large individual differences within the ASC group, this did not reach significance. Although no evidence of transfer to the real-world post-test was shown, anecdotal evidence of classroom transfer was reported. The work presented in this article offers an important contribution to the growing body of research in the context of AI technology design and use for autism intervention in real school contexts. Specifically, the work highlights key methodological challenges and opportunities in this area by leveraging interdisciplinary insights in a way that (i) bridges between educational interventions and intelligent technology design practices, (ii) considers the design of technology as well as the design of its use (context and procedures) on par with one another, and (iii) includes design contributions from different stakeholders, including children with and without ASC diagnosis, educational practitioners, and researchers.

The paradigm of neurodiversity provides a theoretical scaffold to challenge the idea of dyslexia as a deficit, by considering how difficulties related to literacy may reflect possible cognitive strengths and opportunities for learning. In this paper we adopt this perspective which associates dyslexia with strengths in visual, oral and three-dimensional thinking. Our goal is to understand if and how the multimodal affordances of SNS mediate participation and new literacies for dyslexic youth, and how these affordances interact with identity work. Seven young people struggling with literacy were interviewed about their use of SNS. Our results show that the visual affordances of SNS enable new forms of participation and expression, furthering our understanding of visual literacies. Nonetheless, despite the pervasive use of visual affordances to perform identity work, we also find that young people's learning differences are not always obviated but re-constructed, or even confronted in SNS.

The development of social communication skills in children relies on multimodal aspects of communication such as gaze, facial expression, and gesture. We introduce a multimodal learning environment for social skills which uses computer vision to estimate the children's gaze direction, processes gestures from a large multi-touch screen, estimates in real time the affective state of the users, and generates interactive narratives with embodied virtual characters. We also describe how the structure underlying this system is currently being extended into a general framework for the development of interactive multimodal systems.
