This study investigates the approaches adopted by students to a university writing programme designed to help them learn first-year undergraduate science. The research design includes phenomenographic analyses of 19 interviews and 50 open-ended questionnaires, as well as quantitative analyses of the qualitative data. The main results of the study are the close association between the quality of the students' approaches to writing, including when they use technology, to the way they think about writing as a way of learning, and to the level of achievement they reach. The results suggest that writing programmes designed to help students learn science would be improved if their tasks embed issues such as what learning is possible through writing, how new technologies can be used to support meaningful writing and who should be offering models of how to approach university writing most meaningfully.
