Teaching and learning of science. A study on «what, when and how much» students learn about vision

Abstract

What is studied is the experimented learning of a group of students of secondary school education when the specially designed teaching proposal to foster an ontological, epistemic and conceptual change in the way of knowledge is implemented in the classroom. Results show that students have experienced a gradual change in the conceptual model they use to explain sight and the implicit principles that guide the way in which these things happen.
