Introduction
As a junior researcher at KU Leuven and Université catholique de Louvain, I'm currently working on task-oriented dialogue systems/agents for language learning, in the domain of computer-assisted language learning (CALL). I'm a PhD candidate in Linguistics thanks to a SENESCYT scholarship (Ecuador). I am also a professor at Universidad Central del Ecuador. Previously, I worked as a research assistant at Université catholique de Louvain on reflexive writing in general education.

Article
Full-text available
This article presents the results of a systematic review of the literature on dialogue-based CALL, resulting in a conceptual framework for research on the matter. Applications allowing a learner to have a conversation in a foreign language with a computer have been studied from various perspectives and under different names (dialogue systems, conve...
Preprint
Full-text available
The present study offers a meta-analysis of effectiveness studies on dialogue-based CALL, i.e., systems allowing a learner to practice a second language (L2) by interacting with a conversational agent ("bot"). Through a systematic inclusion and exclusion process, screening 419 publications, we identified 17 relevant meta-analysable studies. We made...
Chapter
Full-text available
Dialogue systems allow a user to interact, orally or in writing, with an automated interlocutor, whether it is referred to as a chatbot, a robot, a conversational agent or an intelligent personal assistant. We discuss the different typologies of dialogue-based computer-assisted language learning (CALL), the natural language processing (NLP) technol...
Conference Paper
Full-text available
Neural conversational models require substantial amounts of dialogue data for their parameter estimation and are therefore usually learned on large corpora such as chat forums or movie subtitles. These corpora are, however, often challenging to work with, notably due to their frequent lack of turn segmentation and the presence of multiple reference...
Presentation
Full-text available
Dialogue-based computer-assisted language learning (CALL) encompasses applications that allow a learner to practice a foreign language by carrying a conversation with a computer through unconstrained input. Such systems, whether speech or text-based, present various challenges to the CALL developer, both with the instructional design (degree of ope...
Conference Paper
Full-text available
Dialogue-based Computer-Assisted Language Learning (CALL) covers applications and systems allowing a learner to practice the target language in a meaning-focused conversational activity with an automated agent. We first present a common definition for dialogue-based CALL, based on three features: dialogue as the activity unit, computer as the inter...
Article
Full-text available
This paper addresses the issue of supervised reflective writing in Arts students’ general education. Through analyzing an electronic portfolio device where first year college students had to write reflective reports on extracurricular activities, we studied how they carried out and perceived reflective and critical writing. Results tend to show som...
Article
Full-text available
Dans cet article de synthèse, nous nous faisons d’abord le point sur les différentes approches qui sont faites de la réflexivité, et en particulier des pratiques d’écriture réflexive, en contexte pédagogique. Nous étudions ensuite les tensions auxquelles est confronté un enseignant qui souhaite engager ses apprenants dans des pratiques réflexives d...
Article

À travers cet article, nous exposerons le résultat de nos recherches exploratoires menées auprès d’enseignants du 3e degré de l’enseignement secondaire supérieur en Belgique. Après une analyse du concept de réflexivité dans le champ des sciences de l’éducation, nous chercherons à analyser quelle est la place de ce concept dans les prescriptions did...

Archived project
Identify the kinds of "reflective writing" activities that are realized in the last years of secondary education and in the first years of university (in Belgium), and how these reflective writing activities can help student better prepare for and adapt to the language and theoretical requirements of the university context.
Project
A dialogue system allows a user to discuss with an automated agent controlled by the computer. The project is to develop a task-oriented written dialogue system, or chatbot, allowing language learners with few opportunities to meet native speakers to practice the target language, in this case French, in spontaneous conversations in real-life situations. We will evaluate the impact of such a practice on the development of their L2 proficiency.
