The growth of multimedia is increasing the need for standards to access and search distributed repositories. Recently, the Moving Picture Experts Group (MPEG) has developed the MPEG Query Format (MPQF) to make multimedia access and search easier and interoperable across search engines and repositories. Since MPQF is not supported by any database products including native XML databases and relat...

Although many of the information processing systems are text-based, much of the information in the real life is generally multimedia objects, so there is a need to define and standardize the frame works for multimedia-based information processing systems.

According to cognitive load theory (Sweller, 1999) and Mayer's theory of multimedia learning (Mayer, 2001), replacing visual text with spoken text (the modality effect) and adding visual cues relating elements of a picture to the text (the cueing effect) increase the effectiveness of multimedia instructions. The aim of this study was to test the generalisability of both effects in a classroom s...

In two pilot experiments, a new approach for the direct assessment of cognitive load during multimedia learning was tested that uses dual-task methodology. Using this approach, we obtained the same pattern of cognitive load as predicted by cognitive load theory when applied to multimedia learning: The audiovisual presentation of text-based and picture-based learning materials induced less cogni...
