Successful computer-supported collaborative learning (CSCL) relies on collaborative group engagement, a complex construct characterized by multifaceted, dynamic, socio-emotional, and socio-cognitive processes. This paper provides a detailed analysis of collaborative group engagement, with a particular focus on nonverbal behaviors as indicators of…

This study investigates the progression of students' meaning-making of epigenetic phenomena while discussing multiple visual representations depicted at different levels of biological organization. Semi-structured focus group sessions involving ninth-grade students (aged 15-16) from a Swedish lower secondary school were video recorded. Students'…

Background: Gestures are an integral component in human-to-human communication when the speaker is visually present to the listener. In the past several years, research has examined how computer-generated pedagogical agents can be designed to perform the four main gesture types and what this means for agent persona and learning outcomes. The…

Research has shown that gesture production supports learning across a number of tasks. It is unclear, however, whether gesture production during encoding can support narrative recall, who gesture production benefits most, and whether certain types of gestures are more beneficial than others. This study, therefore, investigated the effect of…

Purpose: Persons with aphasia (PWA) experience differences in attention after stroke, potentially impacting cognitive/language performance. This secondary analysis investigated physiologically measured vigilant attention during linguistic and nonlinguistic processing in PWA and control participants. Method: To evaluate performance and attention in…

We previously observed students gesturing during a symmetry and group theory activity. This prompted additional interviews, wherein we attempted to understand the semiotic function of these gestures. We report here on the gestures that students used in this context to represent symmetry elements, symmetry operations, and other related ideas. In…

The process of spoken word recognition is influenced by both bottom-up sensory information and top-down cognitive information. These cues are used to process the phonological and semantic representations of speech. Several studies have used EEG/ERPs to study the neural mechanisms of children's spoken word recognition, but less is known about the…

This study examines the impact of instructor presence on cognitive load and learning outcomes in video-based learning environments, addressing a significant gap in optimising instructional design for digital education. Utilising eyetracking technology to measure pupil dilation, a reliable proxy for cognitive load, this research compares three…

Gestures accent and illustrate our communication. Although previous studies have uncovered the positive effects of gestures on communication, little is known about the specific cognitive functions of different types of gestures, or the instantaneous multi-brain dynamics. Here we used the fNIRS-based hyperscanning technique to track the brain…

This article foregrounds the role of the learner's experienced and expressive body in the process of action-oriented intercultural second language acquisition (SLA), drawing on phenomenological and related research on embodiment. It suggests that processes of perception, cognition, intentionality, and action are fundamentally shaped by the…

Video materials require learners to manage concurrent verbal and pictorial processing. To facilitate second language (L2) learners' video comprehension, the amount of presented information should thus be compatible with human beings' finite cognitive capacity. In light of this, the current study explored whether a reduction in multimodal…

Co-speech gesture in monolinguals has been linked to several cognitive processes: prompting memory stores, conveying spatial concepts, searching for lexical equivalents, and supporting rhythm and cohesion. The production of co-speech gesture also occurs in spoken language bilinguals. Studies have demonstrated that bilinguals fluent in American…

Adults with developmental disabilities and educational researchers have identified many holes in the practices currently used to educate non-speaking youth with developmental disabilities, especially those with extensive support needs (Kapp, 2020; Taub, et al., 2017). While technology cannot provide a magical, sweeping fix to barriers to…

The self, like the concept of central "gravity", facilitates the processing of information that is directly relevant to the self. This phenomenon is known as the self-prioritization effect. However, it remains unclear whether the self-prioritization effect extends to the processing of emotional facial expressions. To fill this gap, we…

Grounded and embodied cognition (GEC) serves as a framework to investigate mathematical reasoning for proof (reasoning that is logical, operative, and general), insight (gist), and intuition (snap judgment). Geometry is the branch of mathematics concerned with generalizable properties of shape and space. Mathematics experts (N = 46) and nonexperts…
