Scaffolding and peer review methods were combined on an online platform to develop scientific writing skills in an undergraduate organic chemistry lab.Collaboration was encouraged throughout the semester.First students anonymously critiqued lab report sections from their peers through the online platform. Later, small groups produced complete reports built up from the sections covered by peer review. Each student served a different role in the group, moving from a collaborative approach towards independent writing. The culmination of the semester was a complete report, produced independent of peer or instructor guidance. Implementation was accomplished through a series of rubrics, worksheets, and instructor feedback. Preliminary assessment of these curriculum changes indicates that student writing skills improved and that student feedback is mixed, but generally positive. The ultimate goal is the development of writing skills in lower-level chemistry labs in preparation for writing-intensive upper-level labs.
