Poster | Bilingualtek: An Integrated Science-Language Approach for Latinx Preschoolers
Young children engaged in observation, experimentation, exploration, and conversations about their natural world can synergistically develop science and language skills (Lee, 2018). In this poster presentation we discuss the iterative development and results from the initial pilot of Bilingualtek’s instructional approach. This project integrates cultural-linguistically-responsive science-language…

Poster | Attributions of Mathematical Excellence in Teaching and Learning
This project aims to examine how teachers' beliefs about the origins of mathematical excellence, which might be attributed to genetic, social, or personal characteristics, affect racial and gender equity in their classrooms. A three-part study will create, validate, and apply the Attributions of Mathematical Excellence Scale (AMES), correlating scores with race, gender, and achievement equity.…

Poster | Assessing College-Ready Computational Thinking (Collaborative Research: Brown)
Wright maps can provide psychometricians with information about validity based on internal structure, by allowing us to look for banding based on score levels across items. We recently interviewed teachers and trainers about the use of these maps, along with learning progressions and sample student responses to find what was more and less useful, and what features should be added. In this…

Poster | Applying and Refining a Model for Dynamic, Discussion-based Professional Development for Middle School Teachers about Fractions, Ratios and Proportions (Collaborative Research: Brown)
In this design-based research project, we are refining a model for mathematics professional development. We engage middle grades teachers in playful, discussion-based exploration of fractions and proportions through tasks and dynamic "toys” as well as planning for classroom implementation. We are now adding “Connections”, designed to support participants in transitioning from learners to teachers…

Poster | Anchoring High School Students in Real-Life Issues that Integrate STEM Content and Literacy
We present a framework for using scenario-based assessments (SBAs) to measure middle school students' ability to formulate written arguments around socio-scientific issues. We present data showing both the current strengths and limitations of these SBAs. We also present data which shows that, through the process of writing over a 2-week time span, the students showed significant improvements in…

Resource | A Model Comparison Approach to Posterior Predictive Model Checks in Bayesian Confirmatory Factor Analysis
Posterior Predictive Model Checking (PPMC) is frequently used for model fit evaluation in Bayesian Confirmatory Factor Analysis (BCFA). In standard PPMC procedures, model misfit is quantified by comparing the location of an ML-based point estimate to the predictive distribution of a statistic. When the point estimate is far from the center posterior predictive distribution, model fit is poor. Not…
