This paper looks at three case studies within the teaching and learning of chemistry. Each case considers the effectiveness of group learning activities in terms of the ways in which they enhance cooperative learning. Group tasks are generally undertaken in order to encourage learners to develop their understanding of particular issues, lthough one key disadvantage is that much of the process of the group work is lost as soon as the group disbands. The cases explored here aim to: (i) investigate the development of cooperative attitudes among students, looking for significant learning of scientific concepts, (ii) encourage the development of ethical attitudes, to motivate, and then (iii) empower the participants so that they can build upon the communal knowledge that is generated. In this way learners enhance their levels of partnership and cooperation with other members leading to a fuller and broader understanding of the collaboration required within the values of citizenship education. Using science to educate for citizenship is a growing concern across many countries of the world, in this case illustrated by work in Brazil and the UK.
