Building towers selecting from two colors--engaging two students in collaborative problem solving
PurposeEffective teaching
DescriptionMediator/researcher Carolyn Maher of Rutgers University models effectively engaging two students to solve the problem of building towers four high selecting from cubes of two colors, moving from one student to two students to three students and then preparing for demonstration to the class. Carolyn uses questions, eye contact and participation in the problem solving to engage both students in convincing her and each other that "times two" is the answer to the problem.
