An Advanced E-learning Community Proposal Using MS Sharepoint Portal Server
In order to implement e-learning, quite often simple Internet technologies are used, usually without any clear pedagogical approach. Unfortunately this is not quite effective, it restricts learners' exchanges, while influence the quality of resulted knowledge construction. More sophisticated environments are needed when we vision e-learning as taken place in a rich and flexible Learning Community context, for young students or even for adults and professionals. Our proposal consists of an Electr
Investigating multimodal interactions for the design of learning environments: a case study in scien
This thesis focuses on multimodal interactions for the design of a learning environment. The process of designing such systems involves studying the benefits of multimodal interactions in learning. Therefore, it analyses the structure of the interactive space between the learner and the content to be learnt, and introduces and tests a framework to structure it. It proposes that multimodal interactions can encourage rhythmic cycles of engagement and reflection that enhance learners’ meaning con
Platon-1 : quelques dimensions pour l'analyse des travaux de recherche en conception d'EIAH
Le travail présenté dans ce document est centré sur la problématique de la conception des EIAH (Environnements Informatiques pour l'Apprentissage Humain). Dans une première partie, nous proposons une réflexion sur la nature, les objectifs et les difficultés de cette problématique de recherche. Cette analyse conduit à identifier une difficulté centrale, la multiplicité des points de vue qui peuvent intervenir dans un travail lié à la conception d'un EIAH et les incompréhensions prof
A Tailorable Collaborative Learning System that Combines OGSA Grid Services and IMS-LD Scripting
This paper presents Gridcole, a new collaborative learning system that can be easily tailored by educators in order to support their own CSCL scenarios, using computing services provided by third parties in the form of OGSA grid services. Educators employ scripts in order to describe the sequence of learning activities and required tools, with standard IMS-LD notation. Thus, through the integration of coarse-grained tools, that may even offer supercomputing capabilities or use specific hardware
Adapting to When Students Game an Intelligent Tutoring System
It has been found in recent years that many students who use intelligent tutoring systems game the system, attempting to succeed in the educational environment by exploiting properties of the system rather than by learning the material and trying to use that knowledge to answer correctly. In this paper, we introduce a system which gives a gaming student supplementary exercises focused on exactly the material the student bypassed by gaming, and which also expresses negative emotion to gaming stud
Computer Algebra Based Assessment of Mathematics Online
In this paper, we investigate computer algebra based assessment of mathematics online, with a focus on undergraduate students. Introducing a computer algebra system to assist in marking allows a paradigm shift from teacher-provided answers to student-provided answers. The Computer Algebra Based Learning and Evaluation (CABLE) system is presented as an open source infrastructure for mathematical learning objects. Features of the CABLE system, including the modular design, database structure, lear
Socio-cognitive functions of space in collaborative settings : a literature review about Space, Cogn
This document reports on a brief literature review about social and cognitive functions of spatial features used when collaborating in both physical and virtual settings. Those concepts come from various fields like social, cognitive as well as environmental psychology or CSCW (Computer Supported Collaborative Work). I briefly summarize the social and cognitive affordances of spatial features like distance, proxemics, co-presence, visibility or activity in the context of physical and virtual spa
Knowledge, the keystone of TEL design
This talk outlines the arguments supporting the claim that knowledge is the keystone of the design of Technology enhanced learning (TEL) environments. First, I consider the meaning we could attach to knowledge and knowing, and I introduce the notion of conception. Second, I explore how far the problématique of validation is central in our research. And to conclude, I introduce a characterisation of conceptions, which could help in addressing the problem of TEL design at a theoretical level.
What is it like for you?: surveying the learning experiences of disabled students in four HE institu
This paper explores phase one of a four-year study of the learning experiences and outcomes for disabled students. The project employs a longitudinal design with a mixed-methods approach. The main aim is to develop an in-depth understanding of the learning experiences and learning outcomes for a small cohort of students with different impairments in four discipline areas in four different higher education institutions. In particular the study aims to uncover barriers to learning and good pract

Studies in robust estimation and control
Effective monitoring and tight control of chemical, petrochemical and biochemical processes are often hindered by the absence of frequent measurements of important process variables that are related to product quality, the presence of process-model mismatch, unmeasureable disturbances, measurement noise, and highly nonlinear process dynamics. This dissertation presents new methods of nonlinear estimation and control in the presence of such practical problems. Simulation and real-time implementat
Novel heterostructure metal-semiconductor-metal (HMSM) photodetectors with resonant cavity for fiber
Monolithically integrated photoreceivers, optoelectronic integrated circuit photoreceivers (OEIC), are important components for fiber optic communications. Two novel delta modulation doped HMSM photodetectors with resonant cavities have been designed with improved performance in terms of responsivity, speed, sensitivity, and wavelength selectivity to fulfill the increasingly more stringent requirements of transmission systems. The major contributions of the author during the Ph.D. period are as
Gauging the readiness of an institution of higher education to implement change in its distance educ
The democratization of finance, information, and technology has created a new global reality that affects every dimension of society and has transformed the competitive context. In this new reality, higher education is losing its monopoly as a credentialing agent, and it has become vulnerable to market forces from which it has been traditionally insulated. The majority of institutions of higher education have developed distance education programs to create market opportunities; however, in many
Intimate Partner Violence on Campus: A Test of Social Learning Theory
The current study sought to examine the theoretical field of intimate partner and domestic violence research. The research focused on integrated social learning, power-control, and fundamental components of intergenerational transmission and male-support theories. The use of the Conflict Tactic Scale (CTS 2), Seller’s (2003) social learning subscale, and a combination of measures of power-control theory were used to determine the relative strength of learning, power, and male social networks i
An Observational Study Of Pre-Service Teachers’ Classroom Management Strategies
Employee attrition is disproportionately higher in the field of education, especially among novice teachers (Liu & Meyer, 2005). A recent survey of American teachers, conducted by MetLife (2005), found that 20% reported, “maintaining order and discipline in the classroom is the greatest challenge” (p. 5). The focus of this study was the problem of increased teacher attrition rates due to classroom management issues. The participants in the study attended six classroom management workshops t
Essential Science for Teachers: Physical Science. Session 1. What Is Matter?: Properties and Classif
Matter is all around us,its what we and everything else are made of. Yet how do we define matter? What are the properties of matter that set it apart from something that is definitely not matter such as light? In this session, well build a working definition of matter, and distinguish between the different forms that it can take. Well also sort out the difference between essential and accidental properties of matter, and look at the role of classification in science,Students inv
