In this study, we follow students' modeling and covariational reasoning in the context of learning about big data. A three-week unit was designed to allow 12th grade students in a mathematics course to explore big and mid-size data using concepts such as trend and scatter to describe the relationships between variables in multivariate settings.…

This article presents the design and evaluation of a tool for inspecting conceptual models of system behaviour. The basis for this research is the Garp framework for qualitative simulation. This framework includes modelling primitives, such as entities, quantities and causal dependencies, which are combined into model fragments and scenarios.…

Coded experience and effective semiotic systems, organizations of patterns of signs that comprise a system of meaning, have proved essential for the propagation of knowledge. In education, communication via semiotic systems forms an important role in guiding children toward the effective use of information and techniques, and it is important that…

The field of higher education shows a jumble of alliances between fellow institutes. The alliances are strategic in kind and serve an economy-of-scales concept. A large scale is a prerequisite for allocating the budgets for new educational methods and technologies in order to keep the educational services up-to-date. All too often, however,…

The REPRESENTATION Project, 1998-2000, carried out research within elementary schools in six European countries: Denmark, France, Greece, the Netherlands, Spain, and England. Altogether, 31 schools participated, ranging from large inner city schools in Paris and Amsterdam, to a 20-student school in a Greek village. In each school, one class of…

Describes an innovation designed to capitalize on certain benefits of concept maps. Uses computer software with preservice teachers to enable them to construct concept maps that represent their own subject matter knowledge. Contains 21 references. (DDR)

The design and development of GRACILE, a collaborative learning environment in the domain of Japanese language patterns and expressions, is described. The environment is designed to allow learning goals communication, learning activities negotiation, and collaboration between learners. From a group of student models, a potential development level…

This study of physics problem-solving identifies reasoning mechanisms that enable the problem-solver to achieve the transformation to a physics structure of the problem situation. Elaboration is explored as a mechanism in fulfilling this transformation by providing beginning problem-solvers with elaborations that they failed to infer. A card…

A study of first-year college students (n=121) in Taiwan investigated the effects of navigation maps and learner cognitive styles on performance in searches for information, estimation of course scope, and the development of cognitive maps within a hypertext learning course. Students were tested to determine level of perceptual field dependence…

This paper reports on a study that observed students creating structured hypertext documents, and how they try to convey structural information, in order to formulate tentative guidelines/principles for the design of concept mapping tools or hypertext systems with an emphasis on the representation of structural knowledge, and to formulated…
