Because density is unobservable and must be inferred from knowledge about weight and size, it is a difficult concept to teach and learn. Even after traditional instruction, many students still have an undifferentiated concept that mixes characteristics of both weight and density. In this study, researchers tested the effectiveness of a unit they…

A 1986 global survey revealed that mathematics and science are firmly in place in school curricula worldwide, but teaching of technology has a much more tentative hold. All of the countries that responded taught science and mathematics at most levels but technology was taught in only a few countries. In an effort to probe more deeply into the…

This volume is organized into six parts. Chapters 1-5, which make up Part 1, first discuss the forces impinging on algebra in the curriculum and suggest possible directions for change. Chapters 6-8, Part 2, concentrate on concepts and teaching possibilities available prior to the formal introduction of algebra. The notion that algebraic ideas are…
