Karin Knisely’s indispensible handbook provides practical advice to students who are learning to write according to the conventions in biology, covering everything from reading technical literature and writing scientific papers, to preparing lab reports and making oral presentations of scientific findings. Since scientific communication requires unique competencies on the computer (for example, producing Greek letters and mathematical symbols), almost half of the handbook is devoted familiarizing students with helpful features in Microsoft Word, Excel, and PowerPoint—features that are essential to professional quality scientific communication.

Features

Chapter 1 introduces the scientific method and experimental design.

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.

Chapter 4 gives students 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.

Chapter 5 covers the revision process while Chapter 6 offers a sample report highlighting common mistakes.

The Chapters 7 & 8 focus on poster presentations and oral presentations, showing students how these presentation forms differ from papers in terms of purpose, content, and delivery.
