Hubbard, Ruth – Australian Mathematics Teacher, 1992
Discusses the use of the computer software MINITAB in teaching statistics to explore concepts, simulate games of chance, transform the normal variable into a z-score, and stimulate small and large group discussions. (MDH)

Kail, Robert – Developmental Psychology, 1991
Children and adults were tested on six speeded perceptual-motor and cognitive tasks, including a (1) response time task; (2) button tapping task; (3) pegboard task; (4) coding task; (5) picture matching task; and (6) mental addition task. Age-related change in processing time on most of these tasks was described by a single exponential function.…

Gal-Ezer, J.; Zwas, G. – Mathematics and Computer Education, 1990
Elementary error estimation in the approximation of functions by polynomials as a computational assignment, error-bounding functions and error bounds, and the choice of interpolation points are discussed. Precalculus and computer instruction are used on some of the calculations. (KR)

Anderson, Oliver D. – Mathematics and Computer Education, 1990
Discussed is the use, importance, and availability of programmed algebraic manipulation packages. The general power summation formula is presented and an example using a programed numerical verification package is provided. (KR)

Sieradzan, Andrzej – Physics Teacher, 1990
Explained is the effect produced by an optics toy which uses two concave mirrors to produce an illusion. Formulas and calculations used in the explanation are detailed. (CW)

Demby, Agnieszka – Educational Studies in Mathematics, 1993
A class of 32 fourth graders, who studied inverse operations in grades 1-3, was given 3 written tests, each followed by an interview, to see how well they could simplify computations using inverse operations. Most could not evaluate 28 + 75 - 75, for example, without performing all operations. (GW)

Saxe, Geoffrey B.; Gearhart, Maryl; Seltzer, Michael – Cognition and Instruction, 1999
This study analyzed relations between student achievement in the domain of fractions and the extent to which classroom practices are aligned with principles recommended by current reform frameworks. Hierarchical linear-model analyses revealed that alignment of classroom practices with reform principles was related to student achievement in problem…

Butler, Frances M.; Miller, Susan P.; Lee, Kit-Hung; Pierce, Thomas – Mental Retardation, 2001
A literature search to identify and analyze mathematics interventions for students with mild-to-moderate mental retardation found the focus of instruction has shifted since 1989 from basic skills instruction to computation and problem-solving instruction. Techniques such as constant-time delay, peer tutoring, time trials, and direct instruction…

Lan, William Y.; Repman, Judi – Journal of Experimental Education, 1995
Responses of 138 third and fourth graders to failures and successes in mathematics computation were studied in 4 experimental conditions varied by social learning context and modeling. The collaborative learning context increased student persistence after failure and dynamism after success, and modeling increased persistence and dynamism in an…

Vaughan, Timothy S.; Berry, Kelly E. – Journal of Statistics Education, 2005
This article presents an in-class Monte Carlo demonstration, designed to demonstrate to students the implications of multicollinearity in a multiple regression study. In the demonstration, students already familiar with multiple regression concepts are presented with a scenario in which the "true" relationship between the response and…

Kuo, Rita; Lien, Wei-Peng; Chang, Maiga; Heh, Jia-Sheng – Educational Technology & Society, 2004
This paper proposes a methodology to calculate both the difficulty of the basic problems and the difficulty of solving a problem. The method to calculate the difficulty of problem is according to the process of constructing a problem, including Concept Selection, Unknown Designation, and Proposition Construction. Some necessary measures observed…

Verstegen, Deborah A. – Education Policy Analysis Archives, 2004
What is an adequate education and how much does it cost? In 1989, Kentucky's State Supreme Court found the entire system of education unconstitutional--"all of its parts and parcels". The Court called for all children to have access to an adequate education, one that is uniform and has as its goal the development of seven capacities,…

Rickard, Anthony – RMLE Online: Research in Middle Level Education, 2005
Problem solving continues to be a major focus of K-12 mathematics education reform. This case study shows how a teacher's middle school mathematics instruction evolved from teaching problem solving as computation exercises to teaching how to select and implement combinations of problem solving strategies. The teacher's thinking about problem…

Sangwin, C. J. – International Journal of Mathematical Education in Science and Technology, 2003
This article defines "higher level mathematical skills" and details an important class: that of "constructing instances" of mathematical objects satisfying certain properties. Comment is made on the frequency of higher level tasks in undergraduate work. We explain how such questions may be assessed "in practice" without the imposition on staff of…

Gonzalez-Cruz, Javier; Rodriguez-Sotres, Rogelio; Rodriguez-Penagos, Mireya – Biochemistry and Molecular Biology Education, 2003
Enzyme kinetics is a difficult subject for students to learn and for tutors to teach. During the practicals included in the biochemical courses at the Faculty of Chemistry of Universidad Nacional Autonoma de Mexico, we found that the students acquire good training in the calculations to obtain kinetic parameters such as K[subscript m], V[subscript…
