A chatbot is artificial intelligence software that converses with a user in natural language. It can be instrumental in mitigating teaching workloads by coaching or answering student inquiries. To understand student-chatbot interactions, this study is engineered to optimize student learning experience and instructional design. In this study, we…

This qualitative study explored the design and implementation of a humanoid social robot that mediated collaborative interactions among culturally and linguistically diverse kindergarten children in a US school. The robotic mediation was designed to help children have positive interactions with one another. The study was grounded in theories of…

How to improve students' problem-solving skills and creativity and adapt them to the new situation of the twenty-first century is a rather important educational objective at present, and is expected to be for a long time to come. Project-based learning (PBL) is considered to be an approach that can develop students' higher-order thinking skills,…

In formal educational settings, such as online university lectures, instructional videos often consist of PowerPoint slides accompanied by a video or audio explanation from the instructor. It has been assumed that the social cues provided by the instructor's video may facilitate affective processes and affect learning outcomes. Research on…

The purpose of this study was to test the effects of two metacognitive scaffolds on learners' cognition by evaluating student critical thinking skills performance in an asynchronous discussion board and achievement in a blended learning module. The two scaffolds included a systematic protocol for individualized facilitation prompts and an analytic…

This mixed methods study followed an explanatory sequential design to explore the formation, development, and evolution of a formal online teacher community of practice (CoP). The online CoP supported 382 teachers as they implemented the instructional conversation (IC) pedagogy, a collaborative conversation-based pedagogy for culturally and…

The current experimental study examined the effects of graphic organizers in a collaborative learning context where students constructed knowledge during online discussions. As the results could vary depending on how students interacted with the graphic organizers, this study compared two different approaches: instructor-provided versus…

Case studies hold great potential for engaging students in disciplinary content. However, little is known about the extent to which students actually cover the problem space afforded by a particular case study. In this research, we compared the problem space afforded by an instructional design case study with the actual content covered by 16…

This study used a sequential set-up to investigate the consecutive effects of timing of supportive information presentation (information before vs. information during the learning task clusters) in interactive digital learning materials (IDLMs) and type of collaboration (personal discussion vs. online discussion) in computer-supported…

This study examined some of the methodological approaches used by students to construct causal maps in order to determine which approaches help students understand the underlying causes and causal mechanisms in a complex system. This study tested the relationship between causal understanding (ratio of root causes correctly/incorrectly identified,…

Betty's Brain is an open-ended learning environment in which students learn about science topics by teaching a virtual agent named Betty through the construction of a visual causal map that represents the relevant science phenomena. The task is complex, and success requires the use of metacognitive strategies that support knowledge acquisition,…

While assigning student roles is a popular technique in online discussions, roles and the responsibilities allocated to them have not been consistently assigned. This makes it difficult to compare implementations and generate principled guidance for role design. This study critically examined frequently assigned student roles and identified a set…

In this paper we report the results of a study which investigated the affordances of multi-user virtual environments (MUVEs) for collaborative learning from a design perspective. Utilizing a mixed methods approach, we conducted a comparative study of the effect of varying representational and interactional design features on a collaborative design…

Web users in the 21st century are no longer only passive consumers. On a contrary, they are active contributors willing to obtain, share and evolve information. In this paper we report our experience regarding the implementation of Web 2.0 concept in several Computer Ethics related courses jointly conducted at two Universities. These courses have…

This study adopted design and development research methodology (Richey & Klein, "Design and development research: Methods, strategies, and issues," 2007) to systematically investigate the process of applying instructional design principles, human-computer interaction, and software engineering to a performance support system (PSS) for behavior…
