Learning how to interpret ocean acidification with on-line resources in a contextualised experimentation scenario

Abstract

In this paper we present an introductory experience of the process of Ocean Acidification -decrease in the pH of sea water-, as part of the Experimental Sciences course of the Bachelor's Degree in Primary Education. The experience involved the use of on-line resources and contextualized experimentation, in order to promote student's development of scientific competences and to formulate proposals of improvement within the framework of education for sustainability. Satisfactory results are shown in terms of knowledge acquisition, interpretation of the process analyzed here and awareness of environmental problems. We suggest improvements in the educational curriculum and formulate questions which can generate new research. Finally, limitations of the experience regarding its novelty and the lack of adequate educational resources are discussed.
