Discovery of Ideas and Ideas about Discovery : The influence of prior knowledge on scientific discov
Context of this research project. The empirical studies that were carried out for this thesis were performed in the context of the project 'Inductive Learning’,which was funded by the Dutch Organization for Scientific Research (NWO). The inductive learning project aimed at ‘clarifying the major constraints of inductive knowledge development’ (as stated in the research proposal). The constraints of inductive knowledge that were specifically studied in the project were prior knowledge, disc

A Model for Interoperability in Computer Supported Collaborative Learning
Computer Supported Collaborative Learning activities involve combination of complex software tools that often need to interoperate in a wider context of learning. This paper proposes a data model that accommodates requirements of typical collaborative learning situations and facilitates interoperability of tools and interchange of products of collaboration and evaluation data. The model has been tested against various typical tools used for both synchronous and asynchronous collaboration of grou
Educational Tool for Nanophysics Using Multisensory Rendering
The presentation and the evaluation of an educational tool used to teach physical phenomena that take place at a nanometer scale are the central objectives of the work presented in this paper. Through concepts and tools, the real phenomena are connected to the virtual world, which furnish sensorial representations (haptic, visual, auditory) for the student who is experimenting. A computer representation of the nanoscene at the atomic level offers a multisensory tangible artifact of nanoworld ina
Progression in Multiple Representations: Supporting students' learning with multiple representations
Relating multiple representations and translating between them is important to acquire deeper knowledge about a domain. To relate representations, learners have to mentally search for similarities and differences. To translate between representations, learners need to interpret the effects that changes in one representation have on corresponding representations. The question is how presenting representations may improve or hinder the processes of relation and translation. In this study we examin
Teaching proof in a dynamic geometry environment: what mediation?
This paper aims to discuss two issues. First we intend to analyse if and how dynamic geometry software prove to be a communication space for students and how they support students towards proving. Second, we reflect about the use of video-tapes as source of information both for Mathematics Education research and for the teaching practice. In particular we approach the question: how do video-tapes help in the construction of a shared experience in the classroom?

The "Earth Observing System (EOS) Aura is a NASA mission to study the Earth's ozone, air quality, and climate" by researching the composition, chemistry, and dynamics of the Earth's atmosphere. Visitors can learn how Aura is investigating three questions: Is the Earth's ozone layer recovering? Is air quality getting worse? How is Earth's climate changing? Researchers can find extensive details about the flight, spacecraft devices and specifications, and the data processing and validation. Visito
