This study aims to examine the roles of tactile materials and origami models in the perception of concept definitions and representations in geometry applications of individuals with visual impairments. This case study draws on data from eight individuals with visual impairments selected according to the purposive sampling method in a mathematics…

Some physiological concepts, such as physiology of filtration and absorption in the different nephron segments, are so detailed that they can be a challenge to be memorized. This article describes an exercise that solidifies learning as students manipulate, using paper models, "transporters" and "electrolytes" in the…

The study reported here examined the effectiveness of educational robotics combined with GPS/GIS technologies used as "digital manipulatives" in the teaching of concepts in science, engineering, and technology. Based on the success of previous summer camps, the study also examined a scaling-up of the intervention from 38 participants to…

Reviews research on the use of sociodramatic play in developing preschool literacy skills, outlines the development of play centers which can be used to facilitate literacy development, and offers practical suggestions for acquiring the materials needed for the construction of such centers in preschool classrooms and facilities. (MDM)

Describes a University of Alabama program that trained a cadre of elementary teachers to use various manipulatives in their daily mathematics programs. These teachers received a set of manipulatives to share with others and were expected to conduct inservice programs for colleagues. The program increased use of manipulative materials and revealed…

The preparation of prospective teachers to use manipulatives in the classroom involved three dimensions. Each of these dimensions is discussed within the context of the elementary and early childhood teacher education program at Pennsylvania State University. (JN)

Spatial abilities are fundamental to human functioning in the physical world. Spatial reasoning allows people to use concepts of shape, features, and relationships in both concrete and abstract ways, to make and use things in the world, to navigate, and to communicate. Surgeons, pilots, architects, engineers, mechanics, builders, farmers, trades…

Describes the ways in which primary grade science teachers can use hands-on scientific activities to answer children's questions about science. In such activities, children discover and experiment with materials and objects to understand scientific ideas and processes. Suggests that teachers should encourage children's curiosity. (BB)

Discusses North Carolina's alternative assessment program for first and second grades, the process of implementation, knowledge gained from the program, and implications for implementing Standard 6 (focusing on analyzing and interconnecting teaching and learning) of the National Council of Teachers of Mathematics Professional Teaching Standards.…

Discusses methods teachers of young children can use to plan and create interactive, hands-on bulletin boards that make use of moveable pieces. (BB)

Describes features and offerings of Project AIMS (Activities that Integrate Mathematics and Science) which relies on materials developed and written by teachers and uses inexpensive, easily acquired equipment and supplies. The focus is on hands-on mathematics and science. Includes a brief critique of the program. (MKR)

Reports development and results of the Kramer Project, a two-year study of the implementation of a problem-solving, activity-based mathematics program in the elementary grades. Describes the mathematical content covered, participating teachers, instructional materials employed, inservice teacher training provided, and academic achievement gains of…
