A new diagnostic modeling system for automatically synthesizing a deep structure model of a student's misconceptions or bugs in his/her basic mathematics skills provides a mechanism for explaining why a student is making a mistake as opposed to simply identifying the mistake. This report consists of four sections. The first provides examples of…

This is one of a series of reports summarizing the results of the second mathematics assessment conducted by the National Assessment of Educational Progress (NAEP). Nine, 13- and 17-year-olds were assessed during the 1977-78 school year. The assessment measured achievement in various content areas at four levels of cognitive processes (knowledge,…

A survey was conducted to determine: (1) secondary school mathematics teachers' attitudes toward calculator usage in mathematics classes; (2) teacher practices in allowing and/or encouraging the use of calculators; and (3) teachers' perceptions of their schools' policies regarding calculators in the mathematics classroom. The results indicated…

This paper, presented at the 1979 meeting of the American Educational Research Association (AERA) in San Francisco, discusses the effects of calculator availability on the elementary school mathematics curriculum. The rationale for a shift from a computationally based curriculum to a conceptually oriented curriculum utilizing the calculator as an…

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)
