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

J. D. Salinger’s Characters as Existential Heroes: Encountering 1950s America
This dissertation will analyze Salinger’s three main protagonists, Holden Caulfield, Sergeant X, and Seymour Glass, who could not endure the pain of living a spiritual life in America and achieved symbolic or physical death at the end of their stories. It will challenge existential critic William Wiegand, who uses Kierkegaard’s concept of “Angst.” This dissertation acknowledges Wiegand’s use of the concept of “Angst,” but it opposes his conclusion because it is not acceptable from

Writing to Learn Mathematics: A Mixed Method Study
This study sought to address a research gap by studying students who had been taught mathematics using writing. The purpose of this study was to provide an analysis of students’ perceptions of the benefits and drawbacks of this pedagogical approach. The types of writing students performed in mathematics classes were described, and students’ preferences regarding these tasks were analyzed. Finally, a comparison was made between female and male students’ responses in order to see whether gen

Une approche pro-pédagogique du diagnostic cognitif dans les STI: conception, formalisation, et imp
In an Intelligent Tutoring System (ITS), issues related to the design and the implementation of the cognitive diagnosis (DC) of learner's behavior is addressed intuitively according to the specific goals of this STI. From a purely operational viewpoint, this approach is not really bad since the STIs arising from it, "work". However, when it comes to give to DC a pedagogical dimension in the human tutors, a look into perspective on more fundamental considerations promotes reflection in this direc

Information Technology Education in the Sri Lankan School System: Challenges and Perspectives
Introduction of Information Technology into the secondary school curriculum in Sri Lanka is a very recent development. The subject General Information Technology (GIT) was included for G.C.E. Advanced Level Examination in 2005 while plans are afoot to introduce Information Technology as a subject for G.C.E. Ordinary Level from 2008. Results of the first GIT examination held in 2005 clearly show poor performance by students. Considering the large amount of money spent for Information Technology e

Digital literacy – towards a re description of literacy for the digital learning environments
The concepts of ‘digital literacy’ and ‘digital competence’ are the focus in this paper. The paper will argue that the traditional concepts regarding literacy need to be re described and augmented when faced with the challenges and affordances of the digital learning environments. The paper will suggest a theoretical framework for how to understand the ways in which young people include digital technologies into their social and cultural practices. Some examples from the empirical material w

You Are What You Drink!
Contamination in drinking water sources or watersheds can negatively affect the organisms that come in contact with it. The affects can be severe causing illness or, in some cases, even death. It is important for people to understand how they can contribute to the contaminants in drinking water and what treatment can be done to counter these harmful effects. Students will learn about the various methods developed by environmental engineers for treating drinking water in the United States.

Measuring knowledge convergence: Achievement similarity and shared knowledge in computer-supported c
Learning in small groups may result in convergent knowledge outcomes or foster possible prior differences between learners. Few studies, however, measure convergence or divergence of knowledge as an outcome of small group learning. This contribution analyzes knowledge convergence/divergence as an outcome of learning in small groups with the concepts of achievement similarity and shared knowledge rooted in two different theoretical frameworks. Achievement similarity means that learners acquired s

Dialectics for collective activities: an approach to virtual campus design
This contribution is an attempt to systematise our approach to the design of a virtual campus. Activities in the recently started TECFA virtual campus rely on Internet tools, but they concern both distance teaching and presential interactions. Designing learning activities is relatively easy when the learning goal is an activity in itself. In this contribution, we explain how we extend the “learning by doing” approach to the acquisition of declarative knowledge. After fulfilling a pseudo-task,

Can learning from molar and modular worked examples be enhanced by providing instructional explanati
In two experiments we explored how learning from traditional molar worked-out examples—focusing on problem categories and their associated overall solution procedures—as well as from more efficient modular worked-out examples—where intrinsic cognitive load is reduced by breaking down complex solutions into smaller meaningful solution elements—can be further enhanced. Instructional explanations or self-explanation prompts were administered to increase germane cognitive load. However, both int

Elaborating new arguments through a CSCL scenario
The CSCL community faces two main challenges with respect to learning and argumentation. The scientific challenge is to understand how argumentation produces learning, that is to discover which cognitive mechanisms, triggered by argumentative interactions, generate new knowledge and in which conditions. The engineering challenge is to determine how to trigger productive argumentation among students. These two challenges are often investigated in parallel, but this contribution focuses on the lat

Using e-mail to support reflective narration
This article presents an exploratory study of e-mail use for reflective narration. Narration is viewed from three perspectives: the narrating act, the narrative statement, and the story. These perspectives are used to characterize the 69 e-mails that were exchanged between 13 groups of children from three primary schools. The findings show that e-mail narration has monologic and dialogic qualities, and leads to cognitive and personal reflections on the learning task. We conclude that e-mail can
