Images, diagrams and other forms of visualization are playing increasingly important roles in molecular life science teaching and research, both for conveying information and as conceptual tools, transforming the way we think about the events and processes the subject covers. This study examines how upper secondary school students interpret visualizations of proteins in the form of 2D images and animations. A set of 107 students taking different variants of the natural science program answered a questionnaire with open-ended questions about proteins, and 20 were interviewed in semi-structured, revised clinical interviews. The interviews were structured around three 2D illustrations of proteins and an animated representation of water molecules being transported through a channel in the cell membrane. The results from the study indicate occurrence of alternative conceptions relating to scale and systems level, DNA-related problems and confusion about the properties of the cell membrane. Three sources of difficulties regarding the ability to visualize biomolecular processes were identified: the complexity of biomolecular processes, the dynamic nature of the processes and extrapolations between 2D and 3D conceptions.
