A Design Approach to Research in Technology Enhanced Mathematics Education
This thesis explores the prospect of a design science of technology enhanced mathematics education (TEME), on three levels: epistemological, methodological and pedagogical. Its primary domain is the identification of scientific tools for design research in TEME. The outputs of this enquiry are evaluated by a demonstrator study in the domain of secondary school mathematics. A review of existing literature establishes a need for a design perspective in TEME research, but at the same time suggests

Etude de connaissances d'élèves de seconde sur les mutations génétiques.
L'ADN est une notion qui pose problème aux élèves de lycée aussi nous nous proposons d'identifier et de classer les conceptions des élèves sur ce sujet. Pour cette analyse, nous avons utilisé la notion de mutation, qui permet d'étudier à la fois, comme nous le souhaitions, la structure et la fonction de l'ADN. Après avoir effectué une étude bibliographique et une analyse du savoir, nous avons cherché à vérifier l'existence de six niveaux biologiques dans les productions des élèv

Meeting the Challenges in Evaluating Mobile Learning: a 3-level Evaluation Framework
We propose six challenges in evaluating mobile learning: capturing and analysing learning in context and across contexts, measuring mobile learning processes and outcomes, respecting learner/participant privacy, assessing mobile technology utility and usability, considering the wider organisational and socio-cultural context of learning, and assessing in/formality. A three-level framework for evaluating mobile learning is proposed, comprising a micro level concerned with usability, a meso level

Teacher Behavior Ratings of Adolescents with Attention-Deficit Hyperactivity Disorder (ADHD): Interr
This study examined interrater reliability and potential sources of rater bias among teacher behavior ratings for adolescents with Attention-Deficit Hyperactivity Disorder (ADHD). The intent of the study was two-fold: 1) to assess the consistency between teacher behavior ratings for adolescents with ADHD, and 2) to explore potential sources of bias among teacher raters. In schools, intervention decisions for children and adolescents with ADHD are often based on rating scale data collected from

In Search of One's Pack: A Narrative Study of a Working-Class Woman in the Academy
Utilizing an autobiographical approach by comparing and contrasting my story with other scholars’ stories whose social-class backgrounds are similar to mine, and by analyzing this information through the works of scholars whose research has helped others working in the fields of composition and teaching, I explore the crisscrossing of the female sex, working class, and academia. This exploration attempts to uncover the influences of social class and gender on an academic from a working-class b

Dealing with abstraction: case study generalisation as a method for eliciting design patterns
Developing a pattern language is a non-trivial problem. A critical requirement is a method to support pattern writers with abstraction, so as they can produce generalised patterns. In this paper, we address this issue by developing a structured process of generalisation. It is important that this process is initiated through engaging participants in identifying initial patterns, i.e. directly dealing with the 'cold-start' problem. We have found that short case study descriptions provide a produc
