Exploring Quadrilaterals in a Collaborative Computing Environment

Kevin San Lai

(2010) pp. 1–152

I developed a collaborative computing environment, in which each student controls a point in a geometric space, so that a group of four students collectively forms a quadrilateral. I used the van Hiele theory as a framework in designing the learning ...

How Groups Cooperate in a Networked Geometry Learning Environment

Kevin Lai; Tobin White

Instructional Science: An International Journal of the Learning Sciences Vol. 42, No. 4 (July 2014) pp. 615–637

This paper presents a small group computing environment in which four students each control a different point in a geometric space, such that as a group they collectively manipulate the vertices of a quadrilateral. Prior research has revealed that...

Exploring quadrilaterals in a small group computing environment

Kevin Lai; Tobin White

Computers & Education Vol. 59, No. 3 (November 2012) pp. 963–973

Though cooperative learning has been a topic of considerable interest in educational research, there has been little study specific to learning in the mathematics content area of geometry. This paper seeks to address that gap through a design...

Graphing in Groups: Learning about Lines in a Collaborative Classroom Network Environment

Tobin White; Matthew Wallace; Kevin Lai

Mathematical Thinking and Learning Vol. 14, No. 2 (2012) pp. 149–172

This article presents a design experiment in which we explore new structures for classroom collaboration supported by a classroom network of handheld graphing calculators. We describe a design for small group investigations of linear functions and...

Measuring Graph Comprehension, Critique, and Construction in Science

Kevin Lai; Julio Cabrera; Jonathan M. Vitale; Jacquie Madhok; Robert Tinker; Marcia C. Linn

Journal of Science Education and Technology Vol. 25, No. 4 (2016) pp. 665–681

Interpreting and creating graphs plays a critical role in scientific practice. The K-12 Next Generation Science Standards call for students to use graphs for scientific modeling, reasoning, and communication. To measure progress on this dimension,...
