Automatic Generation of Questions from DBpedia
by Oscar Rodríguez Rocha, Catehrine FARON-ZUCKER, Alain Giboin, Aurélie Lagarrigue
Abstract: The production of educational quizzes is a time-consuming task that can be automated by taking advantage of existing knowledge bases available on the web of linked open data (LOD) such as DBpedia. For these quizzes to be useful to learners, their questions must be generated in compliance with the knowledge and skills necessary to master for each subject and school year according to the official educational standards. We present an approach that exploits structured knowledge bases that contain the knowledge and skills, from which it selects a set of DBpedia resources relevant to a specific school subject and year. This set of resources is enriched with additional related resources, through the NEFCE heuristic. Finally, question generation strategies are applied to the graph generated with this set of resulting resources. Likewise, we provide an evaluation of two knowledge bases and of the proposed NEFCE heuristics.

Multi-agent approach for collaborative authoring and indexing of pedagogical materials
by Samir Bourekkache, ABIK Mounia, Okba Kazar
Abstract: In e-learning environment, the learner may feel that he is isolated and disoriented because of the absence of the teacher and the huge number of materials. Moreover, the pedagogical documents have several characteristics so that we must offer the appropriate documents for each learner according to his level, characteristics, and preferences, etc. Consequently, the adaption of the learning content is an important technique. Creating materials, without additional information, makes the delivering of relevant material an impossible task. Consequently, one has to pay attention to the stage of creating of learning content using new technics. In addition, it may not be convenient if we havent additional information about the learner and the learning material (learning objective, prerequisites, and learner background, etc.). Therefore, we develop a multi-agent system that supports a set of authors who create and index educational materials. The indexes are used to manipulate the learning content efficiently by the machine when choosing the appropriate content to satisfy the needs of heterogeneous learners.

Conceptual Clustering of University Graduate Students Trajectories Using Formal Concept Analysis: a Case Study in Lebanon
by Charbel Obeid, Christine Lahoud, Hicham El Khoury, Pierre-Antoine Champin
Abstract: Due to the weak academic advising systems in most schools, students need assistance to explore universities/colleges and study fields that match their interests and future careers. Unfortunately, the orientation programs in most schools are not well designed to cater to students' varied needs. While career orientation programs are much needed at schools, a large number of Lebanese schools have not integrated such programs in their educational systems yet. Thus, this research focuses on developing a hybrid recommender system based on machine learning techniques. Our research focuses on the implementation of the formal concept analysis (FCA) to study university graduates' trajectories. This data mining technique is applied in knowledge presentation and data processing. FCA enables the discovery of hidden knowledge by using association rule mining and machine learning. The objective of this study is to discover the university graduates' trajectories and demonstrate the effectiveness of the FCA technique in data clustering.

Modelling of Factors of E-learning: An ISM Approach
by VIVEK AGRAWAL, Sucheta Agarwal, Anand Mohan Agarwal
Abstract: E-learning imparts information and knowledge, which helps in educating multi-users. Initially, this process has not been fully accepted by various academic and corporate bodies owing to less involvement of human element in the learning process. However, with the advent of information technology era, e-learning has been wholeheartedly accepted. Therefore, considering the growth of e-learning, this study recognizes the plausible factors influencing e-learning and builds up a basic relationship among the identified factors. The objectives of this study are to identify the influencing factors of e-learning and design a model using Interpretive Structure Modeling (ISM), which is followed by MICMAC analysis to categorize the factors under the four clusters. The use of e-learning is not restricted to just school, universities, and colleges, as there is need for the incorporation of the corporate training and coaching institute.

Higher Education Students Perceptions towards Using Facebook as a Learning Platform
by Rdouan Faizi, Maria Rudneva, Samia Soumia Ezzahid
Abstract: Given the ongoing debate among educators regarding the effect of social networks on education, our objective in this paper is to explore students perceptions towards using Facebook as a learning environment. In this vein, based on the survey we conducted among higher education students, it was revealed that 87.4% of the respondents resort to this online community mainly to improve their learning experience. Facebook has, actually, been reported to provide students with an ideal opportunity to access a plethora of learning resources and all class-related information and activities. It also allows them to discuss different topics with classmates and peers and enables them to seek help on learning problems they encounter. Despite the role that Facebook plays in boosting students learning, 72.3% of the subjects noted that no interaction occurs with teachers on this platform. Facebook might, thus, be considered to be more useful for informal rather than formal learning.

Geometrical Tools to Teaching Azeotropy Using Simplified Thermodynamic Models
by Gustavo Platt, F.S. Lobato, F. D. Moura Neto, G.B. Libotte, D.A. Goulart
Abstract: In this work we propose a geometric view of the azeotropy problem, using some simplified models. We demonstrate that the occurrence of azeotropes in binary mixtures can be viewed - geometrically - as the intersection of curves in the plane (for some models, these curves are parabolas). Furthermore, the idea of functions from the plane to the plane is used to understand the azeotropic phenomenon. These ideas are illustrated with two simple cases, with one and two azeotropes, allowing the analysis of a nonusual thermodynamic behavior -- such as double azeotropy -- with simple mathematical tools, by undergraduate students in Chemical Engineering courses.
Keywords: Azeotropes; Functions from the plane to the plane; Double Azeotropy.
