This paper describes the first stages of a project focusing on the use of preservice-teacher-generated e-Portfolios as a means of documenting and assessing inquiry-based teaching and learning. The project is designed to explore ways in which preservice teacher-created e-Portfolios can…

This paper proposes three tests to determine whether a given nonlinear device noise model
is in agreement with accepted thermodynamic principles. These tests are applied to several
models. One conclusion is that every Gaussian noise model for any nonlinear device…

Knowledge management in organizations, the learning objects paradigm, the advent of a new web generation, and the “Semantic Web” are major actual trends that reveal a potential for a renewed distance learning pedagogy. First and foremost is the use of…

A Multi-Agent system, a loosely coupled network of solvers which interact
to find a solution to a problem beyond individual capabilities and knowledge
[29], is a common notion in the literature with application to a broad range
of problems.…

Abstract. In this article we examine an example of collaborative learning with ICT in secondary school science, in order to analyse its characteristics and determine if they answer criteria for an activity of constructivist nature. We retain that constructivism places…

"La región del Alto Golfo de California (AGC) posee gran interés biológico, geológico, químico y físico debido a sus características endémicas, que han sido fuertemente modificadas por actividades humanas en el último siglo. El conocimiento del transporte de sedimentos en…

We propose an organic approach to educational web-based systems where learning objects, operations on these objects, and actors that perform them are aggregated in meaningful ways. The users of a learning system must be able to observe it globally, at…

The IMS Learning Design specification provides a potential means for capturing units of instruction in a machine-readable, consistent way. However, in order for the IMS Learning Design specification to be used widely by educators and instructional designers for whom it…

Abstract. In the context of continued growth in the accessibility of information through the internet, recent advances in theories of self-regulated learning present an opportunity to reexamine how learners work with networked resources in constructivist approaches such as problem-based learning,…
