In this context, we need reliable computational environments to integrate heterog...

This paper presents the results of a study evaluating student perceptions of online assignment submission. 47 students submitted assignments and received feedback via features within the Virtual Learning Environment BlackboardTM. The students then completed questionnaires comparing their experience of online submission and feedback with traditional methods. Results indicated that 88% of student...

Abstract Exact knowledge of natural gas composition is essential in custody transfer to determine the energy content delivery. However, for liquefied (LNG), a reliable determination difficult. Here, we describe design laboratory‐scale reference liquefier that enables validation and calibration optical spectroscopy sensors by providing them with sample metrologically traceable composition. Hence...

The introduction of virtual learning environments (VLEs) has been regarded by some as a panacea for many of the problems in today’s mass numbers modular higher education system. This paper demonstrates that VLEs can help or hinder student engagement and performance, and that they should be adapted to the different types of learner. A project is described that aimed to investigate whether the in...

Virtual learning is a popular teaching modality, and it has been reported in research that there is no significant difference in academic outcome as compared with face-to-face courses. Not all researchers agree with this assertion and some claim it is more difficult to teach math-oriented subjects online. Given that educational psychology theories are effective for teaching quantitative topics ...

Vapour-liquid equilibria (VLE) data are within the most important experimental data to correctly represent the mixtures' behaviour at the saturation boundaries. In the last years, the VLE of several new binary mixtures have been studied by our group in order to find possible alternatives for the traditional refrigerants. The data have been correlated with the Lemmon-Jacobsen model, which is the...

Abstract This paper outlines and describes the effectiveness of a virtual learning environment (VLE) as grammar resource for first year students at university in southern China over two academic years. The resource, named Independent Grammar Study Scheme (IGSS), offered short exercises that were completed 14-week period by cohorts one students. results this study suggest IGSS was successful rai...

The use of digital games in educational settings starts to be accepted and nowadays the discussion is shifting to other issues. An active topic is how to achieve an effective integration of games in education in general and in Virtual Learning Environments (VLE) in particular, taking full advantage of characteristics such as adaptation or in-game assessment. Interoperability requires that the i...

This article describes the implementation of an intelligent agent that provides recommendations for educational resources in a virtual learning environment (VLE). It aims to support pending (undeveloped) student learning activities. It begins by analyzing the proposed VLE data model entities in the recommender process. The pending student activities are then identified, which constitutes the in...
