Didactics of ICT in secondary education: Conceptual issues and practical perspectives
(Journal article; Peer reviewed, 2009)While there is a huge research literature on the field of ICT (Information and Communication Technology) as a tool in teaching and learning, there is much less research on the area of ICT as a subject or similar designations ... -
ICT for inquiry in mathematics: A developmental research approach
(Peer reviewed; Journal article, 2009)Computers and calculators are in general widely used in Norwegian schools, but with limited use in specific school subjects, as particularly in mathematics teaching. Various reports from surveys and research projects ... -
Linear instability of mixed convection of cold water in a porous layer induced by viscous dissipation
(Journal article; Peer reviewed, 2009)An analysis of linear stability of the stationary laminar Darcy flow in a horizontal porous layer is performed. The porous layer is saturated with cold water. The upper plane boundary is assumed to be subject to heat ... -
Reasoning with paper and pencil: The role of inscriptions in student learning of geometric series
(Journal article; Peer reviewed, 2009)The purpose of this article is to analyse how students use inscriptions as tools for thinking and learning in mathematical problem-solving activities. The empirical context is that of learning about geometric series in a ... -
A Taxonomy as a Vehicle for Learning
(Peer reviewed; Journal article, 2009)In this article, we describe the development of a classification system providing a framework for analysis of, and communication about, a subgroup of learning objects. The objects we consider are highly visual, animated, ... -
A conceptual framework for using and evaluating web-based learning resources in school education
(Journal article; Peer reviewed, 2010)Web-based learning resources (WBLRs) have provided teachers with a wide range of new teachingexperiences that are not possible in traditional classroom. However, little research has beendone as to which approach to WBLRs ... -
Developing web-based learning resources in school education: a user-centered approach
(Journal article; Peer reviewed, 2010)Web-based learning resources (WBLRs) are potentially powerful tools for enhancing teachingand learning processes in school education. They can provide teachers and learners with a widerange of new and exciting experiences ... -
Stability of Flow with Viscous Dissipation in a Horizontal Porous Layer with an Open Boundary Having a Prescribed Temperature Gradient
(Journal article; Peer reviewed, 2010)A buoyancy-induced stationary flow with viscous dissipation in a horizontal porous layer is investigated. The lower boundary surface is impermeable and subject to a uniform heat flux. The upper open boundary has a prescribed, ... -
Viscous dissipation and thermoconvective instabilities in a horizontal porous channel heated from below
(Journal article; Peer reviewed, 2010)A linear stability analysis of the basic uniform flow in a horizontal porous channel with a rectangular cross section is carried out. The thermal boundary conditions at the impermeable channel walls are: uniform incoming ... -
Convective Roll Instabilities of Vertical Throughflow with Viscous Dissipation in a Horizontal Porous Layer
(Journal article; Peer reviewed, 2010)The vertical throughflow with viscous dissipation in a horizontal porous layer is studied. The horizontal plane boundaries are assumed to be isothermal with unequal temperatures and bottom heating. A basic stationary ... -
Bounded approximation properties via integral and nuclear operators
(Journal article; Peer reviewed, 2010)Let X be a Banach space and let A be a Banach operator ideal. We say that X has the lambda-bounded approximation property for A (lambda-BAP for A) if for every Banach space Y and every operator T is an element of A(X, Y), ... -
Premeditated automaticity: the role of explicit cognition in the development of obsessive smoking
(Journal article, 2010)Abstract The purpose of the present study was to examine the role of explicit cognitions in relation to the development of obsessive smoking passion. Data derives from a longitudinal internet survey conducted among 939 ... -
Collaborative writing with web 2.0 technologies: education students' perceptions
(Journal article; Peer reviewed, 2011)Executive Summary Web 2.0 technologies are becoming popular in teaching and learning environments. Among them several online collaborative writing tools, like wikis and blogs, have been integrated into educational settings. ... -
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 ... -
A three-dimensional study of the onset of convection in a horizontal, rectangular porous channel heated from below
(Journal article; Peer reviewed, 2012)The onset of convection is studied in a rectangular channel filled with a fluid saturated porous medium, bounded above and below by impermeable isothermal walls at unequal temperatures and laterally by partially conducting ... -
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. ... -
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 ... -
Professional mathematics teacher identity: analysis of reflective narratives from discourses and activities
(Journal article; Peer reviewed, 2012)This article focuses on the methodological use of reflective narratives from discourses and activities of an experienced primary teacher as evidence of her professional identity. The teacher’s reflective narratives emerge ... -
Mediated action in teachers’ discussions about mathematics tasks
(Journal article; Peer reviewed, 2012)This paper presents analyses of teachers’ discussions within mathematics teaching developmental research projects, taking mediation as the central construct. The relations in the so-called ‘didactic triangle’ form the basic ... -
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 ...
