A popular design in large-scale educational assessments as well as any other type of survey is the balanced incomplete block design. The design is based on an item pool split into a set of blocks of items that are assigned to sets of "assessment booklets." This article shows how the problem of calculating an optimal balanced incomplete block…

Over the past decade, apoptosis has emerged as an important field of study central to ongoing research in many diverse fields, from developmental biology to cancer research. Apoptosis proceeds by a highly coordinated series of events that includes enzyme activation, DNA fragmentation, and alterations in plasma membrane permeability. The detection…

The purpose of this study was to examine the effects of a motivationally designed instructional text on motivation and learning. The foundation for motivational design was provided by the combination of a model of motivation in self-regulated learning and the ARCS-approach. The model of motivation is based on concepts like expectancies,…
