This project is using a cross-sectional research design and will generate evidence that is both descriptive [think aloud, think after, written, and drawing protocols] and causal [experimental]. Original data will be collected from graduate students engaged in nanotechnology research using assessments of learning and observation [videography].
We have developed a set of written prompts that ask participants to draw common structures, phenomena, and processes that exist at the nanoscale. The second set of instruments consists of graphics that depict a variety of structures, phenomena, and processes at the nanoscale.
Think aloud, written, and drawing protocols will be analyzed using standard protocol analysis techniques to evaluate the extent to which students use disciplinary knowledge, consideration of audience, and creator's intention when producing and comprehending science graphics.
