in this study a simple and general chemical association theory is introduced. the concept of infinite equilibrium model is re-examined and true mole fractions of associated species are calculated. the theory is applied to derive the distribution function of associated species. as a severe test the application of presented theory to the van der waals mixture model is introduced in order to perfo...

The general set of HCI and Educational principles are considered and a classification system constructed. A frequency analysis of principles is used to obtain the most significant set. Metrics are devised to provide objective measures of these principles and a consistent testing regime devised. These principles are used to analyse Blackboard and Moodle.

The simulation of reactive distillation processes requires binary phase equilibrium data and information about the reaction kinetics and equilibrium. The phase equilibrium data for the binary reacting sub-systems are difficult to measure experimentally since the products of reaction affect the binary equilibrium as soon as they are formed. A novel apparatus has been constructed to measure these...

While academic discussions and investigations of the virtue of three-dimensional virtual learning environments (3D VLEs) have provided ample evidence of student enjoyment (Dillenbourg, Schneider, and Synteta 2002; Strangman and Hall 2003; Nonis 2005), they have proven inconclusive in evaluating the net effect of such environments on student learning. Anecdotal evidence suggests that students ar...

It is widely believed that L2 learners who have positive attitudes towards the target culture and its people are likely to learn language more effectively than those do not possess such attitudes. As technology continues be increasingly integrated into learning, this article aims explore EFL students' acceptance via Virtual Learning Environment (VLE), as well potential advantages of VLE in clas...

Pre-existing issues regarding the wellbeing and mental health of university students have subsequently been compounded by global COVID-19 pandemic. Research signals that anxiety depression symptomology has increased in students’ following outbreak, declined. In response to concerns around Higher Education (HE), support transition remote working during pandemic, we designed implemented an 8-week...

We describe an approach to the generalisation of tools for teaching and learning the skills associated with modelling with diagrams. The paper briefly describes the existing revision tools and our approach to automatic marking of diagrams. We report on our work to generalise both the marking algorithm and the drawing editor in such a way that revision tools can be easily generated for new domai...

Automated testing frameworks, once the preserve of software developers, are now becoming more accessible and useful to the VLE application manager. Automated testing tools which record the clicks and playback tests are just a plugin away. These tools have the capability of allowing ‘front end’ testers to record once and repeat tests in a variety of browsers, ultimately speeding up testing and a...
