Scientific Representation and Design in Collaborative Learning

Science Education . Learning to Use Scientific Concepts

In their abstract, Treagust and Duit ask “whether conceptual change can provide a powerful framework for improving instructional practice in such a way that students’ levels of scientific literacy are significantly increased.” And later in their paper they quote PISA 2000’s definition of scientific literacy as “the capacity to identify questions and to draw evidence-based conclusions in order t...

Fiction and Scientific Representation

Scientific discourse is rife with passages that appear to be ordinary descriptions of systems of interest in a particular discipline. Equally, the pages of textbooks and journals are filled with discussions of the properties and the behavior of those systems. Students of mechanics investigate at length the dynamical properties of a system consisting of two or three spinning spheres with homogen...

Scientific Representation

It is now part and parcel of the official philosophical wisdom that models are essential to the acquisition and organisation of scientific knowledge. It is also generally accepted that most models represent their target systems in one way or another. But what does it mean for a model to represent its target system? I begin by introducing three conundrums that a theory of scientific representati...

The Effect of Visual Representation, Textual Representation, and Glossing on Second Language Vocabulary Learning

In this study, the researcher chose three different vocabulary techniques (Visual Representation, Textual Enhancement, and Glossing) and compared them with traditional method of teaching vocabulary. 80 advanced EFL Learners were assigned as four intact groups (three experimental and one control group) through using a proficiency test and a vocabulary test as a pre-test. In the visual group, stu...
