The Scottish Baccalaureate in Science or Languages is a new qualification, introduced in 2009, currently being undertaken by senior pupils in Scottish schools. To achieve a Baccalaureate, each pupil must complete an Interdisciplinary Project, a research project that bridges two subjects being studied at Advanced Higher level, plus two Advanced Highers. The new qualification is designed to broaden the learner experience, extend subject knowledge and enhance pupils' independent thinking. It will also help pupils develop interpersonal skills, generic skills and confidence. The aim of this article is to describe a model of learning and teaching that demonstrates how fourteen Interdisciplinary Projects for a Baccalaureate in Science could be managed within one school and, through a "whole school approach", be used to enhance pupil learning while embracing the essential elements of the Curriculum for Excellence (CfE), which is designed to produce effective contributors, confident individuals, successful learners and responsible citizens.
