A Student Handbook for Writing in Biology, Fifth Edition, provides practical advice to students who are learning to write according to the conventions in biology. The first chapter introduces the scientific method and experimental design. Because the scientific method relies on the work of other scientists, Chapter 2 provides instructions for finding primary literature using article databases and scholarly search engines. Journal articles have a well-defined structure, but are typically hard to read because they are written for specialists. To help students read and comprehend the technical literature, Chapter 3 describes scientific paper tone and format, provides strategies for reading technical material, emphasizes the importance of paraphrasing when taking notes, and gives examples of how to present and cite information to avoid plagiarism. Using the standards of journal publication as a model, students are then given specific instructions for writing their own laboratory reports with accepted format and content, self-evaluating drafts, and using peer and instructor feedback to refine their writing. Besides writing about it, scientists communicate scientific knowledge through posters and oral presentations. How these presentation forms differ from papers in terms of purpose, content, and delivery is the subject of the last two chapters of the book.
