Scaling Up Innovative Technology-Based Mathematics
We report on the initial attempts at evaluating at scale a particular technological/ curricular innovation that enables more students to develop deeper knowledge. In particular, we present conditions and findings from a…

Formal Specification of Agent-Object Oriented Programs
This paper presents a methodology for the formal specification of agent-object oriented programs. Agent-object oriented programming is a programming paradigm that integrates both agent-oriented programming and object- oriented programming.

Impacts of students’ experimentation using a dynamic visualization on their understanding of motion
This study examines how students' experimentation with a dynamic visualization contributes to their understanding of science. We designed a week-long, technology-enhanced inquiry module on car collisions.

Origami embedding of piecewise-linear two-manifolds
Answering a question of Erik Demaine, we prove that the surface of any bounded polyhedron in Euclidean 3-space can be folded flat.

+Why and how to perform fraud experiments
In this article, we look closer at how to perform fraud experiments.

A unifying perspective on the capacity of wireless ad hoc networks
We present the first unified modeling framework for the computation of the throughput capacity of random wireless ad hoc networks in which information is disseminated by means of unicast routing,…

Bias induced change in effective mobility of polymer transistors
Changes in the mobility, induced by an extended application of a gate bias, are reported in polythiophene TFTs.

Keyholes: selective sharing in close collaboration
We describe keyholes, content annotations where authors or readers enter metadata within a document to indicate what gets shared, with whom, and why.
