Cognitive load theory (CLT) is gaining increasing importance in the design and evaluation of instruction, both traditional and technology based. Although it is well understood as a theoretical construct, the measurement of cognitive load induced by instructional materials in general, and by multimedia instruction in particular, mainly relies on methods that(More)
English-speaking college students who were enrolled in a German course read a 762-word German language story presented by a computer program. For key words in the story, students could choose to see a translation on the screen in English (i.e., verbal annotation) or view a picture or video clip representing the word (i.e,, visual annotation), or both.(More)
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).

When do multiple representations of information in second-language learning help and when do they hinder learning? English-speaking college students (N=152), enrolled in a second-year German course, read a 762-word German story presented by a multimedia computer program. Students received no annotations, verbal annotations, visual annotations, or both for(More)
It has been suggested that computer simulations may be used for intelligence assessment. This study investigates what relationships exist between intelligence and computer-simulated tasks that mimic real-world problem-solving behavior, and discusses design requirements that simulations have to meet in order to be suitable for intelligence assessment.

The job demands-resources model (JD-R model; Bakker & Demerouti, 2014) is well established in occupational research, and the proposed processes it posits have been replicated numerous times. Thus, the JD-R model provides an excellent framework for explaining the occupational well-being of beginning teachers-an occupation associated with particularly high(More)
