This document describes the development and assessment of a scientific journal assignment for introductory biology students. The assignment aims to develop students' abilities to evaluate scientific literature and analyze scientific journal articles. It involves students completing a journal review in four draft sections, receiving feedback, and revising into a final version. Analysis found that using drafts significantly improved student performance and ability to identify and analyze the scientific method compared to completing the assignment without drafts. The assignment was modified over time to further improve learning outcomes.
