Theory and practice related to computing education with racially/ethnically and linguistically diverse groups of preschoolers remain in nascent stages. Accordingly, early childhood educators both require substantial support when integrating culturally responsive computing into curriculum and instruction and offer valuable perspectives on emerging practices. The purpose of this research study is to explore how educator voice-directed efforts support the implementation of a culturally relevant preschool robotics program through multi-year professional development. Through qualitative analyses, we examined how educator voice, conceptualized as perspectives and participation, guided the direction of professional learning situated within a larger research-practice partnership using design-based research (DBR) methodology. By comparing voice across these sessions, we were able to identify what roles educators assumed within the partnership and how those roles shifted over time. Further, we are able to identify the structural and systemic factors that may have affected their participation and implementation. Findings show a contrast in roles across the different stages of the partnership, suggesting implications for embedding professional learning within broader partnership work as a way to cultivate educator leadership and to realize culturally responsive computing education in sustainable ways. 

Generalization allows previous experience to adaptively guide behavior when conditions change. The infralimbic (IL) subregion of the ventromedial prefrontal cortex plays a known role in generalization processes, although mechanisms remain unclear. A basic physical unit of memory storage and expression in the brain is a sparse, distributed group of neurons known as an engram. Here, we set out to determine whether an engram established during learning contributes to generalized responses in IL. Generalization was tested in male and female mice by presenting a novel, ambiguous, tone generalization stimulus following pavlovian defensive (fear) conditioning. The first experiment was designed to test a global role for IL in generalization using chemogenetic manipulations. Results show IL regulates defensive behavior in response to ambiguous stimuli. IL silencing led to a switch in defensive state, from vigilant scanning to generalized freezing, while IL stimulation reduced freezing in favor of scanning. Leveraging activity-dependent “tagging” technology (ArcCreER^T2 × eYFP system), an engram, preferentially located in IL Layer 2/3, was associated with the generalization stimulus. Remarkably, in the identical discrete location, fewer reactivated neurons were associated with the generalization stimulus at the remote timepoint (30 d) following learning. When an IL engram established during learning was selectively chemogenetically silenced, freezing increased. Conversely, IL engram stimulation reduced freezing, suggesting attenuated fear generalization. Overall, these data identify a crucial role for IL in suppressing generalized conditioned responses. Further, an IL engram formed during learning functions to later attenuate a conditioned response in the presence of ambiguous threat stimuli. 

Research practice partnerships (RPPs) that include parents and teachers as cocreators of educational programs provide opportunities to build equitable partnerships yet require university partners to intentionally develop spaces for coconstruction and synergistic interactions. RPPs built within a third space can foster engagement of all partners in the coconstruction of knowledge and practices while assuming roles and navigating partnership work through informal and formal communication. We define a third space as a hybrid, intangible space where inter- and intracultural pedagogies are constructed and shared identity is created from historical and cultural contexts of all partners. This study explored how university partners centered teacher and parent voices in the codesign and piloting phase of a culturally relevant preschool robotics program and facilitated codevelopment within a third space. Through in-depth qualitative coding, we analyzed 6 months of early partnership exchanges to identify how we, as university partners, facilitated discourse and what roles parents and teachers assumed within our third space. Results found that university partners frequently invited participation among partners and used revoicing strategies, and parents and teachers adopted roles as educators and advisors to the program design and implementation. Implications for RPPs include considering how both facilitator-discourse moves and collaborative spaces in which parents and teachers are central to partnership conversations and decisions contribute to successful outcomes.
