Studied the teaching and learning of fractions in two matched groups of 10 9-10-year-olds in the Netherlands. In the experimental group, fractions were introduced using the bar and number line as mental models, while the control group used fair sharing and the circle model. The experimental group showed more proficiency in fractions after 1 year.…

At issue in this study was the extent to which large numbers of classroom teachers were able to implement research-based materials with a minimum of inservice education. Also at issue was whether students of these teachers were able to develop the rich mental images for fractions similar to the ones students from previous Rational Number Project…

Project SEED (Special Elementary Education for the Disadvantaged) is a supplementary mathematics program which applies Socratic discovery methods to mathematics instruction. It was implemented in 10 fourth- and fifth-grade classrooms in Portland to improve mathematics achievement and increase students' esteem for mathematics learning. Student…

Prior to college-level mathematics coursework, students are not routinely provided with the opportunity to engage in the kind of sustained mathematical thinking necessary to solve complex, multistep problems, most likely because of the difficulties that school mathematics teachers face in communicating problem settings and contexts that are…

The school district of the City of Saginaw operates a supplemental educational delivery Chapter 1 system in reading and mathematics, the Elementary Compensatory Education (CE) program and the Secondary CE program. The elementary CE, a push-in program operating in the regular classroom and a pull-out program (periodically taking students out of…
