About this work
OpenStax textbooks are free and openly licensed, which lets us load the full text of each section, evaluate it, and quote it exactly. Biology 2e is used in many introductory college courses.
Reading a textbook fairly. Textbooks summarise; they don't argue every point from the primary data. So we grade whether the evidence presented to the student supports the claim as it is stated to the student, and note where a passage presents an inference as if it were an observation. A textbook that cites strong evidence well gets a high grade.
