Fraction Ball impact on student and teacher math talk and behavior.

We assessed the impacts of Fraction Ball-a novel suite of games combining the benefits of embodied guided play for math learning-on the math language production and behavior of students and teachers. In the Pilot Experiment, 69 fifth and sixth graders were randomly assigned to play four different Fraction Ball games or attend normal physical education class. The Efficacy Experiment was implemented to test improvements made through co-design with teachers with 160 fourth through sixth graders. Researchers observed and coded for use of math language and behavior. Playing Fraction Ball resulted in consistent increases of students' and teachers' use of fraction (SDs = 0.98-2.42) and decimal (SDs = 0.65-1.64) language and number line arithmetic, but not in whole number, spatial language, counting, instructional gesturing, questioning, and planning. We present evidence of the math language production in physical education and value added by Fraction Ball to support rational number language and arithmetic through group collaboration.

More than just a game: Transforming social interaction and STEM play with Parkopolis.

Science, technology, engineering, and math (STEM) focused language and interactions build a foundation for later STEM learning. This study examines the ability of the life-size math and science board game "Parkopolis" to foster STEM language and interaction in young children and their families. This study is part of a larger initiative called Playful Learning Landscapes that aims to create playful learning opportunities for children and families in the places they naturally go. Observational results from 562 families suggest that caregivers and children in Parkopolis demonstrated greater STEM language, engagement, interaction, and physical activity compared to a STEM focused traditional children's museum exhibit. Implications and next steps are discussed in regards to maximizing the number of families that can benefit from Parkopolis' playful STEM learning opportunities.

Executive Function in Learning Mathematics by Comparison: Incorporating Everyday Classrooms into the Science of Learning.

Individual differences in Executive Function (EF) are well established to be related to overall mathematics achievement, yet the mechanisms by which this occurs are not well understood. Comparing representations (problems, solutions, concepts) is central to mathematical thinking, and relational reasoning is known to rely upon EF resources. The current manuscript explored whether individual differences in EF predicted learning from a conceptually demanding mathematics lesson that required relational reasoning. Analyses revealed that variations in EF predicted learning when measured at a delay, controlling for pretest scores. Thus, EF capacity may impact students' overall mathematics achievement by constraining their resources available to learn from cognitively demanding reasoning opportunities in everyday lessons. To assess the ecological validity of this interpretation, we report follow-up interviews with mathematics teachers who raised similar concerns that cognitively demanding activities such as comparing multiple representations in mathematics may differentially benefit their high versus struggling learners. Broader implications for ensuring that all students have access to, and benefit from, conceptually rich mathematics lessons are discussed. We also highlight the utility of integrating methods in Science of Learning (SL) research.
