Megalou, Foteini – International Journal of Mathematical Education in Science and Technology, 2019
This paper describes a research project implemented in a course of Real Analysis II. The aim of this project is to analyse students' comprehension of the limiting behaviour of a function from "R"[superscript 2] to "R" at a point "P"[subscript 0] focusing on the formal definitions. Alternative definitions and other…

Kosyvas, Georgios – International Journal of Mathematical Education in Science and Technology, 2016
This paper presents the results of an experimental teaching carried out on 12-year-old students. An open-ended task was given to them and they had not been taught the algorithmic process leading to the solution. The formal solution to the problem refers to a system of two linear equations with two unknown quantities. In this mathematical activity,…

Skouras, A. S. – International Journal of Mathematical Education in Science and Technology, 2014
This study presents a subset of factors and their association with students' achievement in school algebra. The participants were students who had enrolled in 2007 at the ninth year of Greek public education (third year of middle school). A total of 735 students participated (aged 14-15¬†years) from 37 public secondary schools. The sample consisted…

Bouta, Hara; Paraskeva, Fotini – International Journal of Mathematical Education in Science and Technology, 2013
Research spanning two decades shows that there is a continuing development of 3D virtual worlds and investment in such environments for educational purposes. Research stresses the need for these environments to be well-designed and for suitable pedagogies to be implemented in the teaching practice in order for these worlds to be fully effective.…

Papadopoulos, Ioannis – International Journal of Mathematical Education in Science and Technology, 2013
In this paper a two-stage research study is described focused on problem solving relevant to place-value and on the use of the operations within the calculator environment. The findings show that in this specific environment and via appropriate tasks teachers are provided with a context to better understand what year 5 or 6 pupils know or do not…

Marinos, Andreas – International Journal of Mathematical Education in Science and Technology, 2010
In this work, an attempt is made to evaluate the errors that have to do with the interpretation and construction of graphic representations. Although the students are studying in the second year of technical high school (secondary education), i.e. in schools with an emphasis in technical subjects (post junior secondary), it is observed that they…

Koleza, Eugenia; Pappas, John – International Journal of Mathematical Education in Science and Technology, 2008
In this article, we present the results of a qualitative research project on the effect of motion analysis activities in a Video-Based Laboratory (VBL) on students' understanding of position, velocity and frames of reference. The participants in our research were 48 pre-service teachers enrolled in Education Departments with no previous strong…

Gagatsis, Athanasios; Demetriadou, Helen – International Journal of Mathematical Education in Science and Technology, 2001
Presents an analysis of written solutions to geometry exercises in the last year of Greek Lyceum which showed relatively low performance on vector methods. Justifies pupils' false preconceptions with regard to the concept of vectors, and the strong influence of classical geometry teaching in the previous years. (Author/ASK)
