This study analyses an online scenario-based instrument in which secondary mathematics teachers from across the United States were presented with episodes of mathematics instruction and then asked ...

In this study, we report on the design and use of an apparently unbounded spatial diagram to explore shearing, an area-preserving transformation. Apparently unbounded spatial diagrams are realizations of geometric objects, such as lines, that appear

In this article, we examine spatial inscriptions marked in real or rendered spaces, rather than on two-dimensional surfaces, conceptualize spatial inscriptions from an inclusive materialist perspective and consider realizations of spatial inscription

We investigated how US secondary mathematics teachers expect students to present geometric proofs at the board. We analyzed video records of geometry classrooms and found students to be engaged in a practice that we call proof transcription—i.e., m

As social media has grown, participation in virtual communities focused on the teaching and learning of mathematics has become a norm within the field of mathematics education. Little work has been done within the field to understand the evolving lan

We consider how dynamic diagrams can be used to model multiplication and division. This chapter begins with a review of how multiplication is conceptualized in elementary mathematics education. We consider the affordances of familiar representations

We investigated how secondary mathematics teachers check student geometry proofs. From video records of geometry teachers checking proofs, we conjectured that teachers have different expectations for details that follow from written statements than f

We investigated secondary mathematics teachers' attitudes toward alternative ways of managing instruction on geometric proofs. Participants assigned to different experimental conditions viewed storyboard episodes of instruction. Some episodes showed

We report on the design and development of HandWaver, a mathematical making environment for use with immersive, room-scale virtual reality. A beta version of HandWaver was developed at the IMRE Lab at the University of Maine and released in the sprin

We investigated preservice elementary teachers’ diagrammatic encounters with division by zero. Pairs of preservice teachers explored a transformable diagram where the locations of points on the x and y axes could be continuously varied. Quotients w
