Like three guides in one, Scientific Argumentation in Biology combines theory, practice, and biological content. This thought-provoking book starts by giving you solid background in why students need to be able to go beyond expressing mere opinions when making research-related biology claims. Then it provides 30 field-tested activities your students can use when learning to propose, support, and evaluate claims; validate or refute them on the basis of scientific reasoning; and craft complex written arguments. Detailed teacher notes suggest specific ways to use the activities to enrich and supplement (not replace) what you're doing in class already. You'll find Scientific Argumentation to be an ideal way to help your students learn standards-based content, improve their practices, and develop scientific habits of mind.
