| Exploring how children’s conceptions might advance through their implicit knowledge provides a fundamental view into children’s mathematics and elucidates possible alternative definitions of “learning difference (LD)”. I present an evolving theoretical…
Publication | In this article, the authors outline the main components and the iterative design process we undertook to ensure that the professional supports are relevant and effective for teachers and children.
Product for Educators | Design Technology and Engineering Education (DTEEL) for bilingual English Learner Students is a K-5th grade curriculum focused on language development through engineering design and problem solving. Each grade level includes a series…
Publication | Our work suggests re-conceptualization of research concerning students’ over reliance on example-based reasoning, moving from a view of such reasoning as a stumbling block to quickly overcome toward a view of such reasoning as a necessary and…
Publication | In this article, we use data from interviews, class observations, and an analysis of instructional videos to describe an elementary mathematics specialists' efforts to incorporate flipped instruction for mathematics in her fifth grade class. We…
Product for Educators | The Advancing Reasoning Covariationally (ARC) curriculum is a curriculum for working pre-service and in-service teachers. ARC targets and develops quantitative and covariational reasoning as connecting threads to major secondary…
Publication | This study examined the relationship between student-centered mathematics instruction and adolescents’ behavioral, cognitive, emotional, and social engagement in mathematics and whether the relationship differed by ethnicity.
Publication | The current study investigates two questions: (1) Do screen size and grid density impact a user's accuracy on pattern-matching tasks? (2) Do screen size and grid density impact a user's time on task?
Publication | This study reports results from 113 students and three science teachers from two low-income urban middle schools participating in SciLG. It highlights the role of students’ views of themselves as competent, related, and autonomous in the garden…
Publication | This article focuses on the career paths in higher education taken by 351 doctoral graduates in mathematics education and provides insight into their career path and their resulting workload.
Publication | This chapter explores a way of describing the teacher education curricular materials being developed by mathematics teacher educators through their interaction with the LessonSketch online platform.
Publication | Authors examine how dialogic instruction, a socially dynamic form of instruction, was associated with four learning emotions in mathematics: enjoyment, pride, anger, and boredom.
Publication | This paper studies key usability parameters governing accurate rendering of haptically-perceivable graphical materials
Publication | This article explores how students’ integer value comparisons differed based on question phrasing (which temperature is hottest, most hot, least hot, coldest, most cold, least cold) and on numbers presented (positive, negative, mixed) within the…
Presentation | In this May 2nd webinar, panelists discussed how to prepare for effective informational meetings with congressional staff and craft appropriate messages about preK-12 STEM education research for conversations with local, state, and national…
Publication | In this study we investigate the teaching of the associative property in a natural classroom setting through observation of classroom video of several elementary math classes in a large urban school district.
Publication | Students who earned high marks during the proof semester of a geometry course were interviewed to understand what high-achieving students actually took away from the treatment of proof in geometry. The findings suggest that students had turned…
Publication | The study examines geometry teachers' video club discussions in a two-year professional development intervention that combined lesson study, video clubs, and animation discussions to promote teacher noticing of students' prior knowledge.
Publication | This study explores how preservice teachers (PSTs) transfer the intended specialized content knowledge (SCK) to elementary classrooms.
Publication | In this report, authors describe the results of a rigorous two-year study of the impacts of a mathematics initiative called Ongoing Assessment Project (OGAP) on teacher and student learning in grades 3-5 in two Philadelphia area school districts…
Publication | The ubiquity of touchscreen, mobile tablet technology has resulted in a plethora of “apps for learning” yet few leverage the learning sciences as a design driver. This paper describes our approach to integrating the learning sciences with best…
Publication | Eight middle school mathematics teachers’ perceptions and uses of curriculum materials and the Common Core State Standards for Mathematics (CCSSM) were investigated.
Product for Educators | Model My Watershed is a watershed-modeling web app that enables citizens, conservation practitioners, municipal decision-makers, educators, and students to analyze real land use and soil data in their neighborhoods and watersheds;…
