This paper investigates learner-initiated responses to English language teachers’ referential questions and learner initiatives after teachers’ feedback moves in meaning-focused question-answer sequences to analyze how interactional practices of language teachers, their initiation and feedback moves, facilitate learner initiatives. Classroom discourse research has largely neglected learner init...

Contactless RF-based sensing techniques are emerging as a viable means for building gesture recognition systems. While promising, existing solutions have poor generalization ability when targeting new users, environments or device deployment. They also often require multiple pairs of transceivers and large number training samples each target domain. These limitations either lead to cross-domain...

Development of new functionalities that can enable learning environment to enhance and promote learning is a major concern in the computer-assisted instructional area. Actually, one of the most important issues in this area is distance education. New technologies such as the Internet contribute to this issue. A distance learning environment called CYBERPHYSIQUE is presented in this paper. CYPER...


 In recent years, violence among learners has escalated in many schools South Africa. This raised concern society on whether the measures put place to address problem works. For this reason, we set investigate cause and curb school two a disadvantaged community of Mabopane, Gauteng Province. We selected township setting as context our research. choice is informed by frequent occurrences h...

This work introduces an approach to discover collaboration partners and adequate advising experts in a workplace-embedded collaborative e-learning environment. Based on existing papers dealing with work task and user context modeling, we propose the following steps towards a sucessful collaboration initiation. In the beginning, the user’s current process task needs to be identified (1). Taking ...

In this article we describe TM4L an environment for building, maintaining, and using standards-based, ontology-aware e-learning repositories. It is based on the idea that concept-driven access to learning material implemented as a Topic Map can bridge the gap between a learner and targeted knowledge. One of the driving goals of this work is to increase the reusability of available educational r...

The purpose of this article is to build a model of interaction between the learner and the teacher, where the teacher performs the role of an Intelligent Tutoring System (ITS). If a teacher in the learning process is replaced with a computer system, it should be equipped with a system to adapt to the learner’s cognitive state. We studied factors that influence the learner’s perception of the in...

In recent years, an increasing number of models have been published that can infer if a learner is behaviorally disengaged while working within an interactive learning environment, and can conduct inference using features of data focused on learner interaction with the learning system. In this chapter, we discuss some of the behaviors that have been shown to be amenable to this type of modeling...

A learner’s semantic network represents the learner’s knowledge of words/concepts and the relations among them. The structure of this network is significant as it might reveal aspects of the developmental process that leads to the network. In this work, we use computational modeling to examine the structure of semantic networks of different simulated word learners. We find that the learned sema...
