The home environment is a critical context in which children engage in STEM activities. Caregivers serve as key influencers on their children’s engagement in these activities. This case study of four families explored how caregivers support their child(ren) during moments of problem-solving while completing engineering activities at home and illustrated the variation in caregiver support, caregiver participation/child agency, problem-solving strategies used, and integration of activities into the home. Our findings suggest we need to be purposeful in designing kit activities and supports for caregivers that will contribute to meaningful interactions during STEM activities that draw upon the unique relationship between caregivers and their children in the home. 

Making engages young people with the material world and reflection-in-action, creating promising science learning contexts. Emphasizing relational and social dimensions of making, we conducted a week-long workshop for middle schoolers who are current and aspiring pet companions. Supporting participants’ inquiry into pets’ senses and related behaviors, we asked them to work on maker projects meant to improve their pets’ lives. Following a qualitative analysis of participants’ positioning in relation to their pets, we present case studies of two female participants’ positioning. We find that through the process of making, the two participants demonstrated an increased awareness of pets’ biology and related behavior and their personal interests in pet care, while also differing in what aspects of human-pet relations they focused on. We conclude that through making, especially in contexts with a robust relational draw, youth become attentive to complex and otherwise difficult-to-notice transactions central to taking care of pets. 

Based on the widely recognized situated nature of identity and youth as social producers and products, this qualitative case study reports findings from a week-long informal pet-sciences workshop for middle schoolers who have existing relationships with pets or a strong interest in future pet companionship. Mindful of the structure-agency dialectic, we analyze youth’s wayfaring and trajectories of identification as they learn about their pets at the workshop, accounting for how youth see themselves and their pets and are seen by others. In contrast to a commonly assumed analytic directionality seeing people as moving towards or away from STEM, we find that there were different ways for youth to meaningfully engage themselves in learning about their pets at the workshop. We conclude that attention to fluidity in youth’s identifications can inform us, the adults in the community, of the need to affirm the many possible trajectories that youth may follow. 

Awe is a transformative emotion associated with positive educational and psychological outcomes, and is caused by experiences of vastness that induce accommodation. Vast VR scenes have been found to elicit awe. We examined self-reported causes of awe among grade 3–8 students — a previously unstudied age group regarding awe — in a virtual environment portraying entities over 20 orders of magnitude from atom to Sun. Most students reported feeling awe, around half specifically enough to be coded based on a priori categories drawn from the literature. Vastness of scale (including both large and small entities, and large differences in scale) was the most common cause of awe. Surprisingly, no student responses were related to accommodation. Vastness of evolution and degree of immersion were identified as novel causes of awe. Thus, even young children can experience awe in VR, opening possibilities for productive VR in education at the elementary school level. 

This study takes advantage of advances in Natural Language Processing (NLP) to build an idea detection model that can identify ideas grounded in students’ linguistic experiences. We designed adaptive, interactive dialogs for four explanation items using the NLP idea detection model and investigated whether they similarly support students from distinct language backgrounds. The curriculum, assessments, and scoring rubrics were informed by the Knowledge Integration (KI) pedagogy. We analyzed responses of 1,036 students of different language backgrounds taught by 10 teachers in five schools in the western United States. The adaptive dialog engages students from both monolingual English and multilingual backgrounds in incorporating additional relevant ideas into their explanations, resulting in a significant improvement in student responses from initial to revised explanations. The guidance supports students in both language groups to progress in integrating their scientific ideas. 

We explored how Natural Language Processing (NLP) adaptive dialogs that are designed following Knowledge Integration (KI) pedagogy elicit rich student ideas about thermodynamics and contribute to productive revision. We analyzed how 619 6-8th graders interacted with two rounds of adaptive dialog on an end-of-year inventory. The adaptive dialog significantly improved students’ KI levels. Their revised explanations are more integrated across all grades, genders, and prior thermodynamics experiences. The dialog elicited many additional ideas, including normative ideas and vague reasoning. In the first round, students refined their explanation to focus on their normative ideas. In the second round they began to elaborate their reasoning and add new normative ideas. Students added more mechanistic ideas about conductivity, equilibrium, and the distinction between how an object feels and its temperature after the dialog. Thus, adaptive dialogs are a promising tool for scaffolding science sense-making.
