Computational GRIDs and online laboratories
Many projects addressing the creation of online laboratories have been developed recently. They have a common goal: to enable students and professional learners to get hands-on experience without moving from the places where they are. Nevertheless, the found solutions are often very different among them, and interoperability between different online laboratories systems does not exist. In this paper we present our work around the exploitation of Grid technologies for sharing instrumentation and

Can research on science learning and instruction inform standards for science education?
We contrast the current science education reform effort with the reforms of the 1960s and suggest how the current effort could be enhanced. We identify insights from recent research that we believe can inform the reform process, in particular, to reach all science students and also impart a cohesive view of science. We propose an ldquoalternative modelsrdquo view of scientific explanation and show how this view would contribute to reforms of (1) course goals, (2) social aspects of science learni
