Source use is a central yet often challenging aspect of academic writing in both upper secondary education and higher education. Research shows that pupils and students often struggle to use sources independently in ways that support critical thinking and learning, while also adhering to expected writing conventions. The aim of the dissertation is to explore how source use in academic writing can be made teachable. This is done by identifying possible meanings of this capability in upper secondary school and higher education, as well as the critical aspects that need to be discerned for more advanced source use. In addition, the study examines how principles from variation theory can be used to design instruction that enables the development of this capability.
The dissertation is grounded in a phenomenographic and variation-theoretical framework and comprises four empirical studies. Three phenomenographic studies explore how upper secondary pupils and university students experience source use in academic writing. A fourth study is conducted as a learning study, in which instruction in source use is designed and tested based on principles from variation theory. The empirical material consists of interviews, pupil and student texts, and data from instructional interventions.
The results show that source use can be experienced in four qualitatively different ways, ranging from instrumental and reproductive to more independent and dialogic writing in which sources are used to develop and interrogate ideas. Across the four studies, nine critical aspects of source use are identified: selection, comparison of sources, referencing, reformulation, authorial voice, transparency between voices, writing purpose, audience orientation, and views of writing norms.
The learning study demonstrates that teaching which makes critical aspects visible through systematic variation can support development of more sophisticated source use, even through relatively limited instructional interventions. Taken together, the dissertation offers a teaching-oriented and theoretically grounded approach to understanding and teaching source use in academic writing.
