High-school students’ understanding of science as a result of using the RiverWeb Water Quality Simulator (WQS), a Web-based water management simulation, is described. Eight student pairs participated in a series of science activities, which revolved around using the WQS to explore the impact of land use on water quality. Students received scaffolded pedagogical support from several teachers whi...

Recursion is an important problem solving technique and implementing it on hardware is not trivial. In this research several methods on how to do this are discussed and one is implemented. The goal is to find out if it is possible to automate the process of making recursion possible on hardware and add this automation to the CλaSH compiler. The CλaSH compiler is a compiler from Haskell to VHDL,...

Service-Oriented Architecture (SOA) stands for a standards-based and technology-independent distributed computing paradigm and architectural style which is especially suited to meet the demands of today’s dynamic business applications. Based on a comprehensive set of independent or at most loosely-coupled and network-available software services SOA is supposed to provide a platform for an effic...

Assessing collaborative problem solving (CPS) is an integrated part of the computer-supported collaborative learning (CSCL). We present some preliminary results from a project developed for assessing the CPS using web-based simulation. In the simulation, two participants collaborate via a chat box to complete a task on volcano science. By comparing the responses from 486 individuals and 278 tea...

In this paper, we analyze data gathered from students’ interactions with iList, an intelligent tutoring system that teaches linked lists to computer science (CS) undergraduates. A number of features have been extracted from the log files which were used to; a) build predictive models of students’ performance, b) analyze temporal aspects of students’ problem solving behavior. Our results suggest...

We describe some persistent software infrastructure problems encountered by scientists and engineers who work in application domains requiring extensive computer simulation and modeling. These problems may be mitigated by use of a Problem Solving Environment (PSE), but not all of them are currently being addressed by the PSE research community. We then discuss an approach to designing a toolkit...
