Widespread concern over the use of calculators by young children prompted a broad year-long study of the impact of calculators on elementary school mathematics learning. Two teachers from each of grades 2-6 from five midwestern states participated in the study, which was designed to approximate a "first use" level of calculators in schools. Pupils…

This technical report attempts to (1) provide information on issues and factors involved in analyzing extended degree costs; (2) provide brief explanation of how cost-related tools have been used in allocation of resources in similar degree programs; (3) indicate the types of information that are needed in making cost analysis of the extended…

Much has been said and written about the need for measuring accurately and improving the investment performance of college and university endowment funds, but little has been written about how colleges and universities should report on the status and performance of the investments of endowment funds. When guidelines for reporting are adopted, a…

The course was developed to instruct students in the use of mechanical and/or electronic printing calculators, electronic display calculators, and rotary calculators to solve special business problems with occupational proficiency. Included in the document are a list of performance objectives, a course content outline, suggested learning…

This study sought to evaluate a measure of dyscalculia to determine its validity and reliability. It also tested use of the instrument with seventh graders and ascertained where errors attributed to dyscalculia were also present in an average sample of seventh graders. Results varied. (MNS)

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…
