Student Achievement Effects of TechnologySupported Remediation of Understanding of Fractions
John A. Ross & Catherine D. Bruce
Students have difficulty learning fractions, and problems in understanding fractions persist into adulthood, with moderate to severe consequences for everyday and occupational decisionmaking.... More

Means and the Mean Value Theorem
Jorma K. Merikoski, Markku Halmetoja & Timo Tossavainen
Let I be a real interval. We call a continuous function [mu] : I x I [right arrow] [Bold R] a proper mean if it is symmetric, reflexive, homogeneous, monotonic and internal. Let f : I [right arrow]... More

Performance of Students with Weak Mathematics in FirstYear Mathematics and Science
L J. Rylands & C Coady
In recent years, significant numbers of academics from the science and health disciplines at our institution have found that their students lack the appropriate "mathematical" background to cope... More

Understanding SecondaryTertiary Transition in Mathematics
Megan Clark & Miroslav Lovric
In Clark and Lovric ("Suggestion for a theoretical model for secondarytertiary transition in mathematics", "Math. Educ. Res. J." 20(2) (2008), pp. 2537) we began developing a model for the... More

Mathematics Students' Next Steps after Graduation
Tom Bourner, Sue Greener & Asher Rospigliosi
This article is about what happens to newly minted mathematics graduates. It explores data from the first destination statistics from the perspective of mathematics lecturers and others involved in... More

Isothermal Circumstellar Dust Shell Model for Teaching
G Robinson, I N. Towers & Z Jovanoski
We introduce a model of radiative transfer in circumstellar dust shells. By assuming that the shell is both isothermal and its thickness is small compared to its radius, the model is simple enough ... More

An Improved Heaviside Approach to Partial Fraction Expansion and Its Applications
YiuKwong Man
In this note, we present an improved Heaviside approach to compute the partial fraction expansions of proper rational functions. This method uses synthetic divisions to determine the unknown... More

A Closed Form Solution for an Unorthodox Trigonometric Integral
Yan Wu
A closed form solution for the trigonometric integral [integral]sec[superscript 2k+1]xdx, k=0,1,2,..., is presented in this article. The result will fill the gap in another trigonometric integral [... More

Quadrilaterals and Tetrahedra
Maria Flavia Mammana, Biagio Micale & Mario Pennisi
In this note we show the existence of a surprising analogy between quadrilaterals and tetrahedra, determining some properties that hold for both families of figures. This analogy suggests some new ... More

Closed Forms for 4Parameter Families of Integrals
Thierry DanaPicard & David G. Zeitoun
We compute closed forms for two multiparameter families of definite integrals, thus obtaining combinatorial formulas. As a consequence, a surprising formula is derived between a definite integral... More

Golden Proportions for the Generalized Tribonacci Numbers
Devbhadra V. Shah & Darshana A. Mehta
It is known that the ratios of consecutive terms of Fibonacci and Tribonacci sequences converge to the fixed ratio. In this article, we consider the generalized form of Tribonacci numbers and... More

Moments from Cumulants and Vice Versa
Christopher S. Withers & Saralees Nadarajah
Moments and cumulants are expressed in terms of each other using Bell polynomials. Inbuilt routines for the latter make these expressions amenable to use by algebraic manipulation programs. One of ... More
