Our vision is to make computational modeling a sustained practice in middle school science classrooms. We are working closely with teachers to design a tool and curricula that integrate computational modeling with data practices and enables students to move towards unpacking models and their underlying assumptions. Our research questions involve investigating 1. students modeling trajectories in this environment; 2. how classrooms norms develop over time; and, 3. the interplay between computational modeling and data practices.

This poster provides a methodological overview of the Parents Promoting Early Learning Study's online approach to direct assessment of toddler's math skills during the COVID-19 pandemic. Preliminary data will be presented about the reliability and validity of our measures of children's numeracy and spatial skills. Additionally, we will highlight some of the challenges in conducting online assessments with a socioeconomically diverse sample of families during the pandemic.

Through DEAP, we have created three Problem-Solving Measures (PSMs) that address the Common Core State Math Content for grades 3, 4, 5, and 6 and built a robust validity argument for their use and score interpretations. We have also used vertical equating to link the PSMs with the already functioning middle-school PSMs (grades 6, 7, and 8). We are constructing a DEAP reporting system and investigating how the reporting system formatively informs teachers instructional decisions.

This poster describes the outcomes, dissemination, and scaling of project work from "Fraction Activities and Assessment for Conceptual Teaching (FAACT)." We describe the results of a pilot study for FAACT, free curriculum materials, and how the work has been translated to a new game based project, Model Mathematics Education (ModelME). A link to an intro video for ModelMe's game based curriculum will be shared.

This project explores how secondary mathematics teachers can design mathematically captivating learning experiences using the mathematical story framework to improve aesthetic opportunities with complex mathematical content. This study has developed and tested 28 MCLEs. By comparing captivating lessons with those that students describe as dull or boring, we have identified multiple characteristics of captivating mathematics lessons. Also, in addition to raising student interest, MCLEs positively impact teacher and student questioning.

Through the integration of STEM content and literacy, this project studies the ways teachers implement literacy practices in the STEM classroom. Teachers will facilitate instruction using scenarios that present students with STEM-related issues, presented as scenarios. After reading and engaging with math and science content, students write a source-based argument in which they state a claim, support the claim with evidence from the texts, and explain the multiple perspectives on the issue.
