Compared to a textbook, the Freeman Readiness Readings….

Codon’s textbook replacement—written by Scott Freeman, author of Biological Science—is designed for student learning, not to impress textbook adoption committees. 93% of students complete the readings before class when assigned for points (n ~41,000).

Students learn more effectively with Codon. 

Codon uses evidence-based learning methods such as high-structure, self-testing, spacing, and metacognition—moving students away from less-effective techniques such as cramming and memorizing.

Students save 50–70% versus traditional publisher platforms.

Codon costs $35–$48 per course for five years of access. No price creep—just pricing that reflects what an NSF-funded platform built by scientists should cost.
