This study examined the arithmetic calculation abilities of kindergarten and first-grade children (n=108) with different patterns of cognitive functioning: low language, low spatial ability, general delays, and nonimpaired. Nonverbal, story, and number fact problems were differentially sensitive to variation in cognitive ability. (Author/JDD)

Discussed is the idea that, if students are allowed to use calculators when doing classwork, they should be allowed to use calculators on tests. Examples of calculator-active items are presented that are designed to accurately assess students' learning. (KR)

A mathematics achievement test was taken by 132 U.S. and 110 Japanese fifth graders. Scores were higher for the Japanese, and relatively better for computation than problem solving. The reverse was true for the U.S. students. Results are discussed in terms of amount and kind of exposure to mathematics. (SLD)

The influence that number naming grammar has on the understandings of two-digit numbers and place value of kindergarten children of European and Asian background was examined. Results indicate that Asian verbal/numerical representation patterns naming tens and units in order may be associated with distinctive place value concepts that support…

Describes the construction of a wave generator used to review the algebraic relationships of wave motion. Students calculate and measure the weight needed to create tension to generate standing waves at the first eight harmonics. (MDH)

Examined relations between phonological processing and emerging individual differences in math computation skills. Found that phonological memory, access rate to phonological codes in memory, and phonological awareness were uniquely associated with growth in number of computation procedures mastered from 92.5 to 134.8 months. Phonological…

This article explores how students learned to measure tall objects using a clinometer and some basic calculations. Such activities provide opportunities for students and teachers to learn the usefulness of linking mathematics content and science content to real-world problem-solving situations. (Contains 7 figures.)

The analytically derived asymptotic standard errors (SEs) of maximum likelihood (ML) item estimates can be approximated by a mathematical function without examinees' responses to test items, and the empirically determined SEs of marginal maximum likelihood estimation (MMLE)/Bayesian item estimates can be obtained when the same set of items is…

In this article, rates of return to education for men and women have been estimated for the Spanish case, controlling for the biases appearing in the least squares estimation of the basic Mincerian equation. The results show that the returns for women are greater than those for men. The gender differential increases when taking into account the…

This paper estimates the returns to education for adult male workers in regular and casual wage employment using Indian national survey data at three points in time spanning almost two decades. Both standard and augmented Mincerian wage equations are estimated using a set of human capital measures and other controls after addressing the issue of…

The District of Columbia Tuition Assistance Grant Program (DCTAG), instituted in 1999, allows D.C. residents to attend public colleges and universities throughout the country at considerably lower in-state tuition rates. We use the sharp decline in the price of public colleges and universities faced by D.C. residents to estimate the effects of…

Integrating mathematics with family and consumer sciences (FCS) has enabled youth to pass the Minnesota 8th Grade Math Basic Skills test. The test focuses on the eight content areas: (1) problem solving with whole numbers and fractions; (2) problem solving with percentage/ratio; (3) number sense; (4) estimation; 5) measurement; (6) tables and…

In this article, we present CTRL_SPACE: a design for a software environment with companion hardware, developed to introduce preliterate children to basic computational concepts by means of an animatronic face, whose individual features serve as an analogy for a programmable object. In addition to presenting the environment, this article briefly…

This paper describes a classroom teaching experiment, concerning the concept of probability, with children aged 5 in a kindergarten school. The teaching experiment was based on constructivist and interactionist theories about the learning of school mathematics and lasted one month. The collection of the information was based on the tape-recorded…

Correctional facilities are under increasing pressure to respond to the treatment needs of mentally disordered offenders during their incarceration and to arrange for treatment post release through reentry planning. This paper constructs cost estimates for three different reentry investments using data on the population (n = 2715) of male mentally…
