In their Research Commentary, Kitchen and Berk (2016) argue that educational technology may focus only on skills for low-income students and students of color, further limiting their opportunities to learn mathematical reasoning, and thus pose a challenge to realizing standards-based reforms. Although we share the concern about equity and about…

In this study, we investigated how Grade 3 and 4 students' organizational structure for volume units develops through repeated experiences with a virtual manipulative for building prisms. Our data consist of taped clinical interviews within a micro-genetic experiment. We report on student strategy development using a virtual manipulative for…

Although some research-based educational practices have shown promise, many fail to be implemented at a scale that affects more than a small proportion of children. Further, research on interventions for young children includes mixed results, with most documenting "fadeout" of effects after several years, but some showing lasting…

We used a cluster randomized trial to evaluate the effectiveness of a research-based model for scaling up educational interventions, focusing on the persistence of effects with and without a follow-through intervention. The instantiation of the Technology-enhanced, Research-based, Instruction, Assessment, and professional Development (TRIAD) model…

Studies show that the mathematics test-score gap is evident at every level of schooling and can be linked to students' earlier performance. For example, a mathematics performance gap was found in children as young as three years of age (Case & Griffin, 1990; Jordan, Huttenlocher, & Levine, 1992). Addressing the mathematics performance gap…

The authors summarize the research on the effects of computer use by young children, concentrating especially on implications for social, emotional, and cognitive development. They cover effects on children's language and reading, creativity, and mathematics learning. They note the importance of teacher planning for appropriate computer use in the…

Presents a sampler of statements from "Principles and Standards for School Mathematics" related to standards, goals, and activities for preschoolers. (Author)

Investigates the development of shape concepts within an instructional unit on geometric paths, including the role of noncomputer and computer interactions in that development. Concludes that the computer environment and the activities facilitated students' development of their conceptualizations of the properties of geometric shapes and their…

Examines the effect of a technology-based educational innovation in a school's mathematics program on the knowledge and beliefs of students and teachers, based on recent reform recommendations. Emphasizes unrealized potential and missed opportunities for facilitation due to divergent beliefs of the social groups. Contains 42 references.…

Uses three computer software programs to help students develop algebraic reasoning. Programs include spreadsheets, Logo programming language, and Teasers by Tobbs. (ASK)
