Human interactions with geographical information are contextualized by problem-solving activities which endow meaning to geospatial data and processing. However, existing spatial data models have not taken this aspect of semantics into account. This paper extends spatial data semantics to include not only the contents and schemas, but also the contexts of their use. I specify such a semantic mo...

Introduction. This study takes classifications of musical instruments from three different cultural regions to show that the model of knowledge organization in use is not appropriated for cultural integration. Method. The set of categories used for the analysed instruments have been taken from previous work of M. Kartomi and M. López-Huertas. Analysis. The selected categories have been processe...

Teaching the Arabic language in primary stage must take into account their growth body and mind. The teacher choose appropriate materials for them methods used to teach second language. Otherwise, they should only be taught mother tongue because are of mental physical development need introduced basic concepts wealth new vocabulary own Among teaching as a songs memorization. One most important ...

If “a picture is worth a thousand words,” then a video may be worth a thousand pictures. Videos have been increasingly used in multiple applications, including surveillance, teleconferencing, learning and experience sharing. Since a video captures a scene from a particular viewpoint, it can often be understood better if presented within a larger spatial context. We call such interactive visuali...

The information overload in learning and teaching scenarios is a main hindering factor for efficient and effective learning. New methods are needed to help teachers and students in dealing with the vast amount of available information and learning material. Our approach aims to utilize contextualized attention metadata to capture behavioural information of users in learning contexts that can be...

An experiment explored the impact of explicit guidance (instruction) on the use of abstract symbols or life-like depictions to represent engineering problems. The study examines the effects of guiding learners in the use of abstract or contextualized representations of engineering problems. The study had a 2 (representation conditions: abstract text with abstract diagrams (AA) and contextualize...

Researchers have proposed that immersion could have advantages for tasks involving abstract mental activities, such as conceptual learning; however, there are few empirical results that support this idea. We hypothesized that higher levels of immersion would benefit such tasks if the mental activity can be mapped to objects or locations in a 3D environment. To investigate this hypothesis, we pe...
