The use of the calculator is considered from a functional view and from a pedagogical view. (DT)

In my contribution to this panel I will bring elements from recent research I conducted (Santos, 2004) in Cape Verde aiming to clarify the meaning of learning as participation in social practices--"learning as participation in the social world" (Lave and Wenger, 1991, p. 42). But as my main interest is learning in compulsory education…

Which manual calculation skills are still needed when students use graphic/symbolic calculators or computers with computer algebra systems (CAS)? What should students be able to do manually, i.e. just using paper and pencil? This text is the outcome of a two-day discussion on these questions, held by the four authors. Our answers and proposals are…

This note presents the results of a survey of the power of statistical tests appearing in the Journal Of Educational Measurement from winter, 1969 through fall, 1971. (Author)

Provided is a program listing for the Apple microcomputer which helps children learn to count. From one to nine color square shapes are displayed. Displays are accompanied by sound. The player's score is revealed after 10 responses. A list of program variables is also included. (JN)

Twenty-two seventh and eighth grade students poor in mathematical computation but with average reading comprehension (low math group) were compared with two matched groups: low reading group and no difference group. It was concluded that children with a disability in mathematical computation may be at risk for impulsive and possibly antisocial…

The Euclidean algorithm for finding the greatest common divisor is presented. (MNS)

Describes the history, development and classroom uses of Chisanbop (finger numerals). Cites the results of research utilizing first grade mathematics classes, half using Chisanbop, half not, the Chisanbop group making significantly higher scores on the Iowa Basic Skills Test of computation than the control group. (DS)

Three experiments evaluated performance on a mental multiplication task and the adequacy of several different models of mental addition as extended to multiplication. Results are discussed in terms of a network-retrieval approach to mental arithmetic, the commonalities between addition and multiplication, and rule- versus retrieval-based…

Describes a program written in BASIC, called BIGNUM, that was designed to aid in handling big numbers. The program adds, subtracts, multiplies, divides, and raises to a power integers of up to 1024 decimal digits and is thought to be usable on many types of machines. (MP)

Sixty children aged 2-3 to 5-6 were given four quantity tasks that tested their understanding of "more" and "same." Tasks involving a manipulative response were significantly easier than those involving a yes/no judgment. (Author/RH)

Suggests that ordinal and ratio criteria for equity are independent of one another, but that a plausible mathematical definition of equity must satisfy both criteria under all outcome/input ratio situations. Demonstrates that a modification of the Harris linear formula for equity meets these criteria. (Author/RD)

This article estimates to what extent changes in the unemployment rate over the past two decades have reflected basic cyclical factors in the demand for labor and to what extent they may stem from noncyclical factors. (BM)

Described is the calculator's place in the classroom and its potential for reshaping our computationally oriented curriculum. Activities are suggested for ways calculators can effectively be used to develop four types of mathematical thought. (Author/DS)
