The function of metaphor in science has been labeled as decorative, persuasive, heuristic, instrumental, facilitating or obstructing. It has sometimes been regarded as inspiring, provoking, perverting or destroying rational thought. Metaphor’s positive role has been noted by philosophers, historians of chemistry, and science education researchers. It has been hailed as a descriptive and explanatory device that stimulates and shapes concept development. I discuss how metaphor functions in science generally, then refine this idea through an examination metaphor’s role in chemical thinking (...) in three contexts: the history and philosophy of chemistry, laboratory research practice, and chemical education. I aim to show how metaphor is already operative in the chemist’s use of the concept of chemical element and that this understanding characterizes chemical thinking in general. The chapter concludes with a discussion of a specifically chemical understanding of metaphor. (shrink)

This thesis considers the role of aesthetic meaning-making in elementary school science learning. Children’s aesthetic experiences are traced through their use of aesthetic judgements, spontaneous metaphors and art activities. The thesis is based on four empirical studies: the first two examining children’s language use, i.e. the role of aesthetic judgements and the significance of spontaneous metaphors while learning science and the latter two dealing with how art activities mediate what elementary school children learn in science and what a variety of (...) art activities with different purposes afford elementary school children to learn in science. The theoretical stance emanates from pragmatist theories and includes Dewey’s definition of an aesthetic experience, Wittgenstein’s later work on language-games, and socio-cultural perspectives. The analytic approach used is a practical epistemology analysis developed by Wickman and Östman. The empirical data consists of audio- and video recordings of elementary school children’s (aged 6–10 years) discussions in pairs or small groups during science lessons and photographs of children’s pictures, sculptures and poems from a total of 14 different elementary school classes. The main findings of the empirical studies show how aesthetic meaning-making is continuous with elementary school children’s scientific learning. The thesis shows how elementary school children’s aesthetic experiences are related to whole activities and are crucial for the direction that learning takes. Aesthetic experience is important in terms of how and what elementary school children learn aesthetically and normatively in science class, which has consequences for cognitive learning, the possibility of participating in science class and learning the genre of science. Moreover, it can be seen how children’s prior experiences are recurrently reconstructed and transformed through imaginative processes. (shrink)
