  1. Abstract The field of developmental science is increasingly interested in conducting research that is more representative, equitable, inclusive and generalizable. One way to achieve these aims is to conduct research that positions communities as key collaborators and central contributors to our scientific inquiries. These principles are evident in community science approaches like community‐based participatory research (CBPR) and participatory action research (PAR). We argue that CBPR and PAR can be implemented by developmental scientists. Here, we describe two initiatives that utilized CBPR and PAR. The first initiative is Playful Learning Landscapes (PLL). PLL embeds research from the learning sciences into public spaces to offer playful learning opportunities for children and families, and community science practices are leveraged throughout the process. The second initiative is the Galápagos Education and Research Alliance (GERA). GERA harnesses the tools of community science by working directly with communities in the fragile environment of Galápagos to gather data about ecosystem health and build community‐based plans for climate change adaptation. Together, these two initiatives offer rich examples of how CBPR and PAR principles engender active participation from the community throughout the design and evaluation of a research project. We discuss the opportunities and challenges of using community‐centred approaches. image

  2. Video programs are important, accessible educational resources for young children, especially those from an under-resourced backgrounds. These programs’ potential can be amplified if children are allowed to socially interact with media characters during their video watching. This paper presents the design and empirical investigation of interactive science-focused videos in which the main character, powered by a conversational agent, engaged in contingent conversation with children by asking children questions and providing responsive feedback. We found that children actively interacted with the media character in the conversational videos and their parents spontaneously provided support in the process. We also found that the children who watched the conversational video performed better in the immediate, episode-specific science assessment compared to their peers who watched the broadcast, non-interactive version of the same episode. Several design implications are discussed for using conversational technologies to better support child active learning and parent involvement in video watching.

  3. Children from underserved, minoritized, and immigrant families have less access to early out-of-school STEM learning opportunities. Playful Learning Landscapes increase the accessibility of early STEM learning in everyday public spaces (e.g., bus stops, grocery stores) by merging principles of guided play and STEM learning goals with local community's values. We used community-based design research to (1) identify Latine families’ funds of knowledge related to play, science, and math learning, and (2) create designs for playful environments merging families’ values and practices with guided play and STEM learning principles. Our design partners were 32 parents, primarily Spanish-speaking immigrant mothers from Mexico, and two directors of a local community organization. The design process consisted of co-design sessions, interviews, inductive thematic analysis, elaboration, playtest and feedback, and iteration. Our findings showed that familismo, heritage representation, and the meaning of community spaces influenced the ways families engaged in STEM learning and the learning environments they desired in their community. Moreover, families’ STEM practices were rooted in everyday experiences of playing cultural games, family food routines, and outdoor activities. Incorporating Latine parents in the design process and leveraging their funds of knowledge resulted in culturally situated designs aligned with playful and STEM learning principles. This study contributes to knowledge of Latine families’ values and practices that can help create home-community connections to strengthen children's learning.

  4. Early STEM learning opportunities aligned with families’ funds of knowledge can produce meaningful learning experiences for children. We investigated Latina mothers’ perceptions and values of STEM learning, STEM-related activities with their children, and the early STEM learning experiences mothers designed for community spaces. In a researchpractice partnership, we conducted seven virtual co-design sessions with 32 caregivers and individual interviews with a subset of 10 mothers. A thematic analysis revealed that Latina mothers’ STEM perceptions were primarily informed by school-based notions, yet they also integrated STEM in everyday, family practices such as cultural games. Mothers valued experiences promoting family unity, intergenerational learning, heritage, active citizenship, and ganas. Finally, Latina mothers’ values and practices informed their vision and design of early STEM learning artifacts in the community. Thus, diverse parents’ contributions in design efforts can serve as a mechanism through which stakeholders connect and enhance children’s learning experiences across contexts.
