Describes a simple, inexpensive experiment in which students determine the heats of combustion of common solid, liquid, and gaseous fuels. The experimental apparatus, procedures, calculations and results are discussed. (CW)

Shows how model rocketry can be included in physics curricula. Describes rocket construction, a rocket guide sheet, calculations and launch teams. Discusses the relationships of basic mechanics with rockets. (CW)

Discusses the status of the testing of computational estimation. Suggests ideas to promote needed immediate actions and examines issues related to effective assessment of computational estimation. (PK)

Suggests that the mathematics curriculum for young children can grow from children's literature. Examples given encourage children to use a variety of thinking skills including classifying, forming hypotheses, selecting strategies, and creating problems. (PK)

Two major ways to view the numbers to 100 are counting by ones and grouping by tens and ones. Research suggests that early understanding of numbers comes from counting and that place value instruction cannot be hurried. (PK)

Presents three traditional problems from discrete mathematics with alternative solutions and discussion of those solutions. (PK)

Contains activities for grades 1 through 8 to develop skills in estimation. Designed to help students deal with numbers sensibly and acquire problem solving competency, the estimation activities involve measurement, telling time, computation, and problem solving. (PK)

First, fourth, seventh, and tenth graders were timed when solving simple and complex addition problems, then were presented similar problems in untimed interviews. Manipulation of confusion between addition and multiplication, where multiplication answers were given to addition problems (3 + 4 = 12) indicated an interrelatedness of these…

This information brief examines four factors contributing to Florida's overall high graduation rates in public four-year institutions: (1) Graduation rates for the largest race/ethnic groups were higher than for the nation as a whole; (2) The gaps between racial/ethnic groups were smaller than in the nation as a whole; (3) Florida's largest…

The focus of this study was to investigate mental computation conceptual frameworks that Heirdsfield (2001c) formulated to explain the difference between proficient (accurate and flexible) mental computers and accurate (but not flexible) mental computers. A further aim was to explore the potential for students' developing efficient mental…

This study investigated the nature of spatial ability, as measured by four instruments based on spatial orientation and visualization, and its relationship to the mathematical performance of elementary school pupils. Participating in the study were 127 elementary school students, 72 boys and 55 girls, ages 10 to 11 years. Spatial ability was…

This collection of eight lesson plans is designed to assist teachers in providing mathematics instruction to elementary and secondary education students with different types of disabilities. The lessons use tactics for teaching mathematics content derived from Lovitt (1995), who summarized techniques found to be effective in increasing the…

When looking at the relationship between individual earnings and schooling, there are potential sources of bias which arise due to individual education choices; individuals of higher unobserved ability or with higher unobserved payoffs from schooling may for instance invest more in education. This paper reviews alternative models and estimation…

Math teaching involves more development of computational skills than problem solving and concept analysis. Presented are four areas to consider in attacking the problem. (MD)
