Using assessment for learning mathematics with mobile tablet based solutions
(Journal article; Peer reviewed, 2014)This article discusses assessment for learning in mathematics subjects. Teachers of large classes face the challenge of regularly assessing students’ ongoing mathematical learning achievements. Taking the complexity of ... -
Asymptotic behavior of an odd-order delay differential equation
(Journal article; Peer reviewed, 2014)We study asymptotic behavior of solutions to a class of odd-order delay differential equations. Our theorems extend and complement a number of related results reported in the literature. An illustrative example is provided. -
Oscillation of second-order neutral differential equations
(Journal article; Peer reviewed, 2013)We study oscillatory behavior of a class of second-order neutral differential equations relating oscillation of these equations to existence of positive solutions to associated first-order functional differential inequalities. ... -
Oscillation results for second-order nonlinear neutral differential equations
(Journal article; Peer reviewed, 2013)We obtain several oscillation criteria for a class of second-order nonlinear neutral differential equations. New theorems extend a number of related results reported in the literature and can be used in cases where known ... -
Mathematical learning opportunities in kindergarten through the use of digital tools: Affordances and constraints
(Journal article; Peer reviewed, 2013)This study aims at scrutinising the mathematical learning opportunities of children engaging with digital tools and the emerging affordances and constraints faced in such settings. By adopting a sociocultural perspective ... -
Für die Ehre des menschlichen Geistes – Ein neuer Blick auf eine bekannte Kontroverse zwischen Fourier und Jacobi über die Rolle der Anwendungen der Mathematik
(Journal article; Peer reviewed, 2013) -
„Die Gottesluft der freien Forschung“ – Jacobis Verhältnis zur französischen Mathematik aus politischer Sicht
(Journal article; Peer reviewed, 2013) -
Critical alignment in inquiry-based practice in developing mathematics teaching
(Journal article; Peer reviewed, 2013)This paper reports a case study from a mathematics teaching developmental research project. The theoretical foundation for the research comprises communities of inquiry and critical alignment, with which the developmental ... -
Convective instability in a horizontal porous channel with permeable and conducting side boundaries
(Journal article; Peer reviewed, 2013)The stability analysis of the motionless state of a horizontal porous channel with rectangular cross-section and saturated by a fluid is developed. The heating from below is modelled by a uniform flux, while the top wall ... -
Effect of a finite external heat transfer coefficient on the Darcy-Benard instability in a vertical porous cylinder
(Journal article; Peer reviewed, 2013)The onset of thermal convection in a vertical porous cylinder is studied by considering the heating from below and the cooling from above as caused by external forced convection processes. These processes are parametrised ... -
Dynamics of a single species in a fluctuating environment under periodic yield harvesting
(Journal article; Peer reviewed, 2013)We discuss the effect of a periodic yield harvesting on a single species population whose dynamics in a fluctuating environment is described by the logistic differential equation with periodic coefficients. This problem ... -
An algorithm for discretization of real value attributes based on interval similarity
(Journal article; Peer reviewed, 2013)Discretization algorithm for real value attributes is of very important uses in many areas such as intelligence and machine learning. The algorithms related to Chi2 algorithm ( includes modified Chi2 algorithm and extended ... -
Investigating technical and pedagogical usability issues of collaborative learning with wikis
(Journal article; Peer reviewed, 2012)Wikis have been recently promoted as tools that foster collaborative learning. However, there has been little research devoted to the criteria that are suitable to address issues pertinent to collaborative learning. This ... -
Pedagogical criteria for successful use of wikis as collaborative writing tools in teacher education
(Journal article; Peer reviewed, 2012)Wiki is a Web 2.0 technology that potentially promotes collaborative writing, group discussion and interaction. However, little research has been done as to which criteria are suitable to address pedagogical issues that ... -

Using the interactive learning environment aplusix for teaching and learning school algebra: A research experiment in a middle school
(Journal article; Peer reviewed, 2011)Most software tools that have been developed with the aim of helping students to learn school algebra have not yet achieved successful results in classroom. Almost all of them are menu-based systems that provide ... -
First-year engineering students’ use of their mathematics textbook - opportunities and constraints
(Journal article; Peer reviewed, 2012)The role of the mathematics textbook at tertiary level has received limited exposure in previous research although it is likely that students work individually and that some of this work depends on the use of the textbook. ... -
Onset of convection in a porous rectangular channel with external heat transfer to upper and lower fluid environments
(Journal article; Peer reviewed, 2012)The conditions for the onset of convection in a horizontal rectangular channel filled with a fluid saturated porous medium are studied. The vertical sidewalls are assumed to be impermeable and adiabatic. The horizontal ... -
Revisiting the didactic triangle: from the particular to the general
(Journal article; Peer reviewed, 2012)The basic notion of a didactic triangle is explained with historical annotations on its origins and subsequent theorization in the literature. Instances of its application to classroom environments to demonstrate its ... -
Kindergarten teachers’ accounts of their developing mathematical practice
(Journal article; Peer reviewed, 2012)This study explores kindergarten teachers’ accounts of their developing mathematical practice in the context of their participation in a developmental research project. Observations and interviews were analysed to elaborate ...
