En enseignement postsecondaire, la mise en œuvre de pratiques pédagogiques inclusives dépend à ce jour d’initiatives individuelles des enseignants. La pandémie de COVID-19 a toutefois forcé la mise en ligne des cours, amenant les enseignants à revoir leurs pratiques. L’objectif de cette étude consiste à analyser l’évolution des usages de pratiques...

La mise en œuvre de pratiques d'enseignement inclusives dans l'enseignement postsecondaire dépendait, jusqu'à présent, d'initiatives individuelles du corps professoral. Cependant, la pandémie de COVID-19 a poussé les enseignants à repenser leurs pratiques et à déplacer leurs cours en ligne. L'objectif de cette étude exploratoire est d'analyser l'év...

The realities of the 21st century have led professors and lecturers to renew their learning assessment practices so that they are more adapted to and contextualized in the current professional world. Despite advances in teaching and learning, assessment methods may still deviate from practice in authentic contexts. Although some instructors are alr...

Background Blended online courses, which combine synchronous and asynchronous online activities, have expanded rapidly in higher education. How to enhance student engagement in such courses is unclear, although it is recognized that student engagement is malleable through instructional strategies. Objectives Given the above, this study aims to exa...

Cet article présente les résultats d’une étude ayant pour objectif l’élaboration et la validation d’une échelle de mesure de la professionnalisation des étudiants et étudiantes universitaires en sciences de la santé. Des éléments de preuve de contenu, de processus de réponse et de structure interne de cette échelle ont été apportés au fil de l’étud...

The aim of this study was to verify if external factors influence persistence in online courses in higher education. These external factors, borrowed from Kember’s (1995) model, included some students’ characteristics; cost benefits; social integration of adult students (enrolment encouragement, study encouragement, and family support); and externa...

Blended courses, which combine face-to-face and online learning experiences, are showing substantial growth in higher education. Such a course modality has also been identified in the literature as a favorable ground for increasing student engagement and accordingly, diverse learning outcomes. Although the importance of the instructor’s role in a b...

Blended synchronous learning (BSL) represents several contexts that enable to bring remote students into the classroom, in real time, by the means of videoconferencing, web conferencing and virtual world. As BSL seems to be more and more implemented in many higher education institutions, especially in the current context of the COVID‐19 pandemic, a...

This qualitative study examined how teachers fostered student engagement in blended learning (BL), i.e., blended, blended online, and blended synchronous courses that combine synchronous and asynchronous activities. Twenty semi-structured interviews with teachers in various disciplines, at the undergraduate or graduate level in four universities, w...

Blended courses are rising in business education, and new modalities have emerged to increase flexibility of students. HyFlex courses combine online asynchronous activities with “flexible-synchronous” activities where students choose to attend online synchronously, face-to-face, or online asynchronously through recordings, bringing them full flexib...

This study aimed at building a reliable and valid scale for environmental factors related to student persistence in online courses, particularly relevant for adults or lifelong learners. Drawing on Kember and colleagues (1994)’ social integration and external attribution scales and subscales as a starting point, data collected in Canadian universit...

Blended course modalities combine synchronous activities (face-to-face or in virtual classrooms) with asynchronous online activities, and they represent a fertile ground for enhancing student engagement. However, studying student engagement in these environments requires the development of a measurement scale, which is the purpose of this paper. Th...

Les modalités de cours hybrides, qui combinent des activités synchrones (en classe ou virtuelles) et en ligne asynchrones, représentent un terrain potentiel d’augmentation du niveau d’engagement des étudiants dans leurs cours. L’étude de l’engagement des étudiants dans ces modalités nécessite toutefois l’élaboration d’une échelle de mesure, soit l’...

Online courses are growing in higher education, resulting from an increased access to information and communication technologies. While such courses allow time and/or space flexibility for both students and instructors, they also promote active learning and require more autonomy from the students. In this paper, we present the main design features...

The purpose of this study was to examine the features that foster the academic and social integration of students enrolled in blended synchronous courses (BSC). Many studies and models have considered academic and social integration to be important determinants of student persistence and success in higher education programs and courses. In keeping...

Having a child who lives with a Type 1 Diabetes (T1D) can represent a high burden for parents. The objective of our study is to identify and analyze the main challenges expressed by parents so that health care services better meet the needs of parents of T1D children. Semi-structured interviews were conducted with parents of 19 T1D children regardi...

In online or blended environments, the Community of Inquiry (CoI) framework sets that a meaningful educational experience derives from the interrelation of teaching, social and cognitive presences. Each presence is subdivided, resulting in a structure in ten categories at the basis for the CoI survey instrument. Although the survey structure in thr...

The Delay Management Problem for Public Transportation (DMP) arises in the context of the operational management of an intermodal public transportation network and has the aim of increasing the attractiveness of the network itself. Many passengers often have to use different lines to cover the trip from their origin to the desired destination and t...

Motivated by an application in highway pricing, we consider the problem that consists in setting profit-maximizing tolls on a clique subset of a multicommodity transportation network. We formulate the problem as a linear mixed integer program and propose strong valid inequalities, some of which define facets of the two-commodity polyhedron. The num...

This paper considers a single-vehicle Dial-a-Ride Problem in which customers may experience stochastic delays at their pickup locations. If a customer is absent when the vehicle serves the pickup location, the request is fulfilled by an alternative service (e.g., a taxi) whose cost is added to the total cost of the tour. In this case, the vehicle s...

In this paper, a variant of the Traveling Salesman Problem with Time Windows is considered, which consists in minimizing the sum of travel durations between a depot and several customer locations. Two mixed integer linear programming formulations are presented for this problem: a classical arc flow model and a sequential assignment model. Several p...

Consider the problem that consists in maximizing the revenue generated by tolls set on a subset of arcs of a transportation network, and where origin-destination flows are assigned to shortest paths with respect to the sum of tolls and initial costs. In this work, we address the instance where toll arcs must be connected, as occurs on highways. Our...

In this study, we establish a parallel between two classes of pricing problems that have attracted the attention of researchers in marketing, theoretical computer science and operations research, each community addressing issues from its own vantage point. More precisely, we contrast the problems of pricing a network or a product line, in order to...

Passengers travelling in public transportation networks often have to use different lines to cover the trip from their origin to the desired destination. As a consequence, the reliability of connections between vehicles is a key issue for the attractiveness of the intermodal transportation network and it is strongly affected by some unpredictable e...

Consider the problem of maximizing the revenue generated by tolls set on a subset of arcs of a transportation network, and where origin-destination flows are assigned to shortest paths with respect to the sum of tolls and initial costs. This work is concerned with two new combinatorial formulations of this problem and provides a framework for deriv...
