This paper presents an approach of collecting contextualized attention metadata combined from inside as well as outside a LMS and analyzing them to create feedback about the student activities for the teaching staff. Two types of analyses were run on the collected data: first, key actions were extracted to identify usage patterns and tendencies throughout the whole course and then usage statist...

This study describes the process of constructing proxy variables from recorded log data within a Learning Management System (LMS), which represents adult learners’ time management strategies in an online course. Based on previous research, three variables of total login time, login frequency, and regularity of login interval were selected as candidates from the data set, along with a guideline ...

The development of Web 2.0 and social software applications was not initially aimed for education, but its influence in this field, especially in e-learning, is recently recognized as positive. New approach to e-learning inspired by these technologies is called e-learning 2.0. It emphasizes social learning using different tools available on the web rather then integrated systems like LMSs. This...

In modern learning environments, the lecturer or educational designer is often confronted with multi-national student cohorts, requiring special consideration regarding language, cultural norms and taboos, religion, and ethics. Through a somewhat provocative example we demonstrate that taking such factors into account can be essential to avoid embarrassment and harm to individual learners’ cult...

Current learning management systems (LMS) feature some pending issues. In particular, although we are moving towards a new wave of standard-based LMS, there are few implementations addressing the adaptation problem as a whole. In any case, however, adaptation is bound to be a permanent issue inasmuch as learning is a personalised and adaptive process, which from start to finish should consider ...

This case study explores the affordances of a specific Facebook group created by college students, as perceived by the group members. The main focus is to investigate if Facebook groups have an educational value. Furthermore, three secondary research topics emerged: comparison of the group’s perceived affordances of faculty as opposed to the ones of students; comparison of the group’s perceived...

We study the dimension of “random” Euclidean sections of direct sums of normed spaces. We compare the obtained results with results from [LMS], to show that for the direct sums the standard randomness with respect to the Haar measure on Grassmanian coincides with a much “weaker” randomness of “diagonal” subspaces (Corollary 1.4 and explanation after). We also add some relative information on “p...

This study investigated how students used Learning Management Systems (LMS) to interact with each other, collaborate, and co-construct knowledge without mediation by the instructor. Results indicate that students successfully used the LMS to interact and, to a significant extent, collaborate with each other, but there was very little evidence of knowledge co-construction within the LMS. The res...
