The undisputed increase of the relevance of mental work load is confronted with a lack of qualified or at least well documented measuring instruments covering all important aspects.The COPSOQ (Copenhagen Psychosocial Questionnaire), a comprehensive instrument for the assessment of psychosocial factors at work, was tested in a partly modified version in a large German sample (N = 2561 employees)...

One hundred and eleven 10th graders read an expository science text on the dipole character of water molecules (ca. 1600 words). Reading instruction was varied according to a 2 2 experimental design with factors ‘drawing pictures of text content on paper’ (yes, no) and ‘mentally imagining text content while reading’ (yes, no). The results indicate that drawing pictures, mediated through increas...

Learning introductory software development is a difficult task and students often perceive programming subjects as requiring significantly more work than others. This paper describes a learning model for programming that has its basis in cognitive load theory. This theory suggests that there are three types of cognitive load that learners experience: intrinsic which is determined by the mental ...

We consider the problem of dynamic load balancing in arbitrary (connected) networks on n nodes. Our load generation model is such that during each round, n tasks are generated on arbitrary nodes, and then (possibly after some balancing) one task is deleted from every nonempty node. Notice that this model fully saturates the resources of the network in the sense that we generate just as many new...
