Precalculus Teachers' Perspectives on Using Graphing Calculators: An Example from One Curriculum
Ilyas Karadeniz & Denisse R. Thompson
Graphing calculators are hand-held technological tools currently used in mathematics classrooms. Teachers' perspectives on using graphing calculators are important in terms of exploring what... More
pp. 1-14

The Effect of Explanations on Mathematical Reasoning Tasks
Mathias Norqvist
Studies in mathematics education often point to the necessity for students to engage in more cognitively demanding activities than just solving tasks by applying given solution methods. Previous... More
pp. 15-30
-
The Effectiveness of Resources Created by Students as Partners in Explaining the Relevance of Mathematics in Engineering Education
Michelle Dunn, Birgit Loch & Wendy Scott
First-year engineering students often struggle to see the relevance of theoretical mathematical concepts for their future studies and professional careers. This is an issue, as students who do not ... More
pp. 31-45
-
Advanced Mathematics Communication beyond Modality of Sight
Mina Sedaghatjou
This study illustrates how mathematical communication and learning are inherently multimodal and embodied; hence, sight-disabled students are also able to conceptualize visuospatial information and... More
pp. 46-65
-
ICT Integration in Mathematics Initial Teacher Training and Its Impact on Visualization: The Case of GeoGebra
Monika Dockendorff & Horacio Solar
This case study investigates the impact of the integration of information and communications technology (ICT) in mathematics visualization skills and initial teacher education programmes. It... More

Are Middle School Mathematics Teachers Able to Solve Word Problems without Using Variable?
Burçin Gökkurt Özdemir, Emrullah Erdem, Tugba Örnek & Yasin Soylu
Many people consider problem solving as a complex process in which variables such as "x," "y" are used. Problems may not be solved by only using "variable." Problem... More

The Concept of Invariance in School Mathematics
Shlomo Libeskind, Moshe Stupel & Victor Oxman
In this paper, we highlight examples from school mathematics in which invariance did not receive the attention it deserves. We describe how problems related to invariance stimulated the interest of... More
pp. 107-120

Kurtosis: A Forgotten Moment
Lynn G. McAlevey & Alan F. Stent
The treatment of kurtosis in textbooks is both sparse and contradictory with applications rarely discussed. To address this, an easily understood definition of kurtosis is introduced and important ... More
pp. 120-130
-
An Elementary Algorithm to Evaluate Trigonometric Functions to High Precision
B. Tomas Johansson
Evaluation of the cosine function is done via a simple Cordic-like algorithm, together with a package for handling arbitrary-precision arithmetic in the computer program Matlab. Approximations to... More
pp. 131-137
-
Guided Discovery of the Nine-Point Circle Theorem and Its Proof
Orly Buchbinder
The nine-point circle theorem is one of the most beautiful and surprising theorems in Euclidean geometry. It establishes an existence of a circle passing through nine points, all of which are... More
pp. 138-153
-
Dynamic Geometry as a Context for Exploring Conjectures
Arsalan Wares
The purpose of this paper is to provide examples of "non-traditional" proof-related activities that can explored in a dynamic geometry environment by university and high school students... More
