The Science of Learning
We didn't guess our way to interactive publishing. We spent two decades watching how students really learn — and built ActiveBook on the strongest findings in the learning sciences.
Doing beats reading — by about six times
Carnegie Mellon University's research on online courseware, running for over a decade, established what they call the doer effect: students who complete interactive practice while reading learn roughly six times more per activity than students who only read or watch. Crucially, follow-up studies showed the relationship is causal — the doing itself produces the learning.
In every ActiveBook: practice is woven into the reading itself — every few paragraphs, students do something: answer, predict, manipulate, build.

The largest meta-analysis of undergraduate STEM education ever conducted — 225 studies, published in PNAS — found that exam performance rose by roughly 6% (0.47 standard deviations) under active learning, and students in traditional lecture courses were 1.5 times more likely to fail than peers in active classrooms.
In every ActiveBook: the "lecture" becomes a laboratory. Simulations and guided inquiry turn passive exposition into active investigation.

Roediger and Karpicke's landmark studies on the testing effect showed that actively recalling material produces dramatically better long-term retention than re-studying it — while re-reading creates a dangerous illusion of mastery. Repeated low-stakes retrieval is one of the most robust results in cognitive psychology.
In every ActiveBook: frequent, low-stakes "check yourself" moments trigger retrieval — spaced across chapters so knowledge sticks for the exam and beyond.

Misconceptions harden when they go uncorrected. Immediate, specific feedback — delivered while the problem is still in working memory — corrects errors before they consolidate and keeps learners in a productive struggle rather than a frustrating one.
In every ActiveBook: adaptive, step-by-step feedback responds the moment a student errs — not days later when the graded quiz returns.

Learning objectives first
Our instructional designers map your chapter goals before a single interaction is built — so every element serves mastery, not novelty.
Interactions by evidence
Each concept gets the treatment the research recommends: simulation for systems, retrieval for facts, worked examples for procedures.
Analytics close the loop
Engagement and mastery data flow back to you and your instructors — so the book improves edition after edition, in real time.
