on the meteorological site at the Experiment station, evapoEvaporation from fibreglass pans painted silver was less than ration from the metal pan was greater. from Class 'A' (metal) pans. Painting the fibreglass pans with dark paint decreased the difference in evaporation but the seasonal differences were not uniform. It was also shown that placing a screen over both types of pans decreased ev...

Recent technological advances in mobile devices enable the connection of classrooms with other virtual and physical spaces. Some approaches aim at helping teachers carry out learning situations across such spaces. However, these proposals tend to be isolated from other activities in teachers’ current common practices, and do not allow teacher-controlled flexibility of what students do during th...

3D virtual worlds, such as Second Life, are increasingly being used for delivering e-learning for different genres of students. As part of an ongoing research to evaluate different digital design aspects of using these emergent virtual learning environments, the aim of this paper is to investigate whether the overall satisfaction of students from their 3D learning spaces is dependent on their s...

For e-learning systems to be successful, proper understanding of the learner is crucial. This can be done with the use of learners’ profiles. However, there is a need for the availability of such information for mobile learning environments to make it available when the learner roams between different spaces. This paper investigates the application of RFID technologies for this use. We suggest ...

Today’s science graduates are more likely to become scientists without postgraduate research training, yet they seldom possess the skills to work as scientists. There is therefore a need for undergraduate students to not only learn scientific concepts, but also be able to inquire using scientifically sound methods. This ALTC funded project has investigated how Australian university educators ar...

and References AbstractThis paper analyzes the convergence of information technology infrastructures and traditionaleducational spaces and proposes flexible criteria for material-virtual, hybrid learning environments. Idevelop the concept of built pedagogy to account for the ways that built environments teach valuesthrough their constraints upon social action and interaction and...

The goal of this study was to identify the factors that limit the survival of the red-eared slider turtle Trachemys scripta during long-term anoxic submergence at 3 C. We measured blood acid-base status and tissue lactate and glycogen contents after 13, 29, and 44 d of submergence from ventricle, liver, carapace (lactate only), and four skeletal muscles. We also measured plasma Ca , Mg , Na , K...

Carrying out collaborative learning activities (supported by technologies or not) typically involves the coordination of multiple participants, in their dynamic assignment to groups and roles and in the distribution of resources and tools to specific group or individuals. While the mechanisms required to address these coordination aspects in digital educational spaces have been largely studied,...
