After reviewing several assumptions that support the future ubiquitousness of computers in society and in scholarly research, summarizes three interrelated frameworks for developing instructional computing. (GC)

Proposes the hypothesis that preschoolers have number concepts based on the numbers 1-5 rather than on the decimal structure. Results suggest that children understand numbers to 5 as a privileged anchor. Proposes a new model for a representational system of numbers. (Author/DR)

This paper on the language of zero (1) deals with the spoken and written symbols used to convey the concepts of zero; (2) considers computational algorithms and the exception behavior of zero which illustrate much language of and about zero; and (3) the historical evolution of the language of zero.

Although breathing is a universal activity among physicists (and others), few have bothered to estimate the number of molecules inhaled in a single average breath. Some simple calculations and comparisons related to this phenomenon are provided to improve students' appreciation of the awesome numbers related to Avogadro's number. (JN)

A teacher in a large suburban elementary school in East Tennessee found that her fourth grade students had poor number sense and relied almost solely upon algorithmic procedure to solve math problems. Therefore, mental math was difficult for these students, so the daily number talks method was employed to strengthen number sense. However, no…

This study was designed to derive the distribution of a test statistic based on normal probability plots. The first purpose was to provide an empirical derivation of the critical values for the Line Test (LT) with an extensive computer simulation. The goal was to develop a test that is sensitive to a wide range of alternative distributions,…

A common cause of failure in accounting is student inability to mentally perform basic arithmetic computations. The first step toward solving the problem of arithmetic deficiencies would be to make a calculator available to all students, especially since they will be working in a numerical, machine-dominated world.

Investigated the development of informal addition in Dioula (A Moslem ethnic group from West Africa) from childhood to adulthood and the effect of schooling on mental arithmetic. Compares these data with results from a study of children from the United States. (MK)

Changes in children's cognitive strategies for solving simple subtractions were studied by analyzing verbal reports given immediately after each problem. The development of children's cognitive processes involved a gradual shift from more primitive and less demanding memory strategies to reconstructive memory processes to retrieval processes.…

Describes a program written for a programmable pocket calculator that computes the frequency response of linear systems. (Author)

A sample run is given of a BASIC program used to determine possible genetic characteristics of offspring of parents with known genetic characteristics. (MK)

Presents an activity that concerns children's reasoning about counting from the perspectives of informal mathematics, work center mathematics, and cardboard box mathematics. (ASK)

Presents some known and lesser-known features of the number 11. (KHR)

Discusses an algorithm from Vedic mathematics that has similarities to FOIL and the standard algorithm for multiplication. (Author/NB)

Describes how 7th grade students were transitioned from using informal, conceptual methods to solving proportion problems using a formal procedure. (YDS)
