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. 

Abstract Introduction This research examined the classification accuracy of the Quick Interactive Language Screener (QUILS) for identifying preschool-aged children (3;0 to 6;9) with developmental language disorder (DLD). We present data from two independent samples that varied in prevalence and diagnostic reference standard. Methods Study 1 included a clinical sample of children (54 with DLD; 13 without) who completed the QUILS and a standardized assessment of expressive grammar (Syntax subtest from the Diagnostic Evaluation of Language Variation–Norm Referenced; Structured Photographic Expressive Language Test–Preschool 2nd Edition; or Structured Photographic Expressive Language Test–3 rd Edition). Study 2 included a community sample of children (25 with DLD; 101 without) who completed the QUILS and the Auditory Comprehension subtest of the Preschool Language Scales–5th Edition (PLS-5; Zimmerman et al., 2011). Discriminant analyses were conducted to compare classification accuracy (i.e., sensitivity and specificity) using the normreferenced cut score (< 25th percentile) with empirically derived cut scores. Results In Study 1, the QUILS led to low fail rates (i.e., high specificity) in children without impairment and statistically significant group differences as a function of children's clinical status; however, only 65% of children with DLD were accurately identified using the norm-referenced cutoff. In Study 2, 76% of children with DLD were accurately identified at the 25th percentile cutoff and accuracy improved to 84% when an empirically derived cutoff (<32nd percentile) was applied. Conclusions Findings support the clinical application of the QUILS as a component of the screening process for identifying the presence or absence of DLD in community samples of preschool-aged children. 

What if the environment could be transformed in culturally-responsive and inclusive ways to foster high-quality interactions and spark conversations that drive learning? In this article, we describe a new initiative accomplishing this, called Playful Learning Landscapes (PLL). PLL is an evidence-based initiative that blends findings from the science of learning with community-based participatory research to transform physical public spaces and educational settings into playful learning hubs. Here, we describe our model for conducting this research, which is mindful of three key components: community input, how children learn best, and what children need to learn to be successful in the 21st century economy. We describe how this model was implemented in two PLL case studies: one in a predominantly Latine community and the second in early childhood education classrooms. Furthermore, we describe how research employing our model can be rigorously and reliably evaluated using observational and methodological tools that respond to diverse cultural settings and learning outcomes. For example, our work evaluates how PLL impacts adult–child interaction quality and language use, attitudes about play and learning, and community civic engagement. Taken together, this article highlights new ways to involve community voices in developmental and educational research and provides a model of how science can be translated into practice and evaluated in culturally responsive ways. This synthesis of our process and evaluation can be used by researchers, policymakers, and educators to reimagine early educational experiences with an eye toward the built environment that children inhabit in everyday life, creating opportunities that foster lifelong learning.
