Using diagrams as tools for the solution of non-routine mathematical problems
(2009)
The Mathematics education community has long recognized the importance of diagrams in the solution of mathematical problems. Particularly, it is stated that diagrams facilitate the solution of mathematical problems because ...
Geometric and algebraic approaches in the concept of "limit" and the impact of the "didactic contract"
(2009)
The present study explores students’ abilities in conversions between geometric and algebraic representations, in problem- solving situations involving the concept of “limit” and the interrelation of these abilities with ...
University students' conceptions of function
(2004)
“Function”, as it is understood today, formulates one of the most important concepts of mathematics. Nevertheless, many students do not sufficiently understand the abstract but comprehensive meaning of function and problems ...
An empirical four-dimensional model for the understanding of function
(2006)
Based on a synthesis of the relevant literature, this study explores students’ abilities in four aspects of the understanding of function: problem solving, concept definition, examples of function, recognizing functions ...
Geometric and algebraic approaches in the concept of complex numbers
(2006)
This study explores pupils’ performance and processes in tasks involving equations and inequalities of complex numbers requiring conversions from a geometric representation to an algebraic representation and conversions ...
Relations between secondary pupils' conceptions about functions and problem solving in different representations
(2007)
The present study explores pupils’ constructed definitions of the concept of function in relation to their abilities in dealing with tasks of functions involving different forms of representations and problem solving tasks. ...
The effects of different modes of representation on the solution of one-step additive problems
(2007)
This study investigated the role of different modes of representation, i.e., verbal description, decorative pictures, informational pictures and number line, in solving additive change problems. Data were collected from ...
A comparison between the hierarchical clustering of variables, implicative statistical analysis and confirmatory factor analysis
(2008)
This study aims to gain insight about the distinct features and advantages of three statistical methods, namely the hierarchical clustering of variables, the implicative method and the Confirmatory Factor Analysis, by ...
