In traditional physiology teaching materials, which structure the human body into decoupled subsystems (e.g., respiratory and cardiovascular) isolated in separate chapters, there is a ubiquitous absence of…

In this paper we report on the sustained research and development work at the AMSTEL Institute of the University of Amsterdam to improve mathematics and science education at primary and secondary school level, which has lead amongst other things to the development of the integrated computer working environment Coach 6. This environment consists of…

Building and evaluating artifacts specifically for K-12 education, technologists committed to design sciences are needed along with an approach to evaluation increasing the systemic transfer from research and development into school settings. The authors describe THE VIRTUAL LAB scanning electronic microscope simulation, including (a) its…

The concept of a community of practice (CoP) is prevalent in several venues for teachers' professional development, especially in online environments. However, there are few descriptive accounts that effectively represent a CoP in a manner that will be of use to other designers. In order to illuminate potential difficulties which may arise when…
