Balance Board Math (BBM) aims to explore what kinds of learning become possible when the balance system participates directly in mathematical activity. In BBM, learners rock on a wooden balance board to explore a range of mathematical concepts including absolute value, angles, and functions. This project reimagines human-computer interactions in math instructional design to accommodate … Continue Reading »

## Distributed Learning in Practice and Theory

At the Center for Connected Learning and Computer-Based Modeling (Uri Wilensky, Director), we were: (a) building agent-based computer models as learning tools for students to simulate scientific, mathematical, and social phenomena; and (b) analyzing emprical data from our design experiments to develop theoretical models of cognition, teaching, and learning. These theoretical models were by and large expressed … Continue Reading »

## Paradigmatic Didactical Mathematical Problematic Situations

In collaboration with Betina Zolkower, Ph.D., Brooklyn College, CUNY. In the PDMPS project, we designed, implemented, and evaluated an experimental curriculum for pre-service teachers and future education researchers enrolled in graduate-level college courses on mathematics cognition, learning, and instruction. Central to this design are selected ‘paradigmatic didactical-mathematical problematic situations,’ i.e., unique activities evoked as contexts for … Continue Reading »

## Defining Practice

Overview Defining, a central practice in mathematics, is different from the daily practice of clarifying the meaning of words. Mathematics students often have trouble formulating definitions, interpreting new definitions, and using definitions in proof and problem solving. And whereas students may be able to state many mathematical definitions, these are often presented and received as … Continue Reading »

## Giant Steps for Algebra

Overview Giant Steps for Algebra (GS4A) is the dissertation project of Kiera Chase. GS4A is a design-based research project investigating the cognition, teaching, and learning of early algebra. The project is centered on a technology-based activity, in which students use computer-interface resources so as to model a narrative about a giant burying stolen treasure on a … Continue Reading »
