zyBooks vs. Traditional Textbooks

• With a single lesson, zyBooks improved student performance by 16%
• Least-prepared students improved by 64%
• Students self-reported significantly higher levels of engagement with the zyBook
• Students voluntarily spent twice as long with the zyBook, even though the zyBook had half the text
• 96% of instructors polled recognize zyBooks for boosting their students’ confidence with the subject matter

STUDENTS WILL EARNESTLY COMPLETE INTERACTIVE WEB MATERIAL

• When using zyBooks, fewer than 3% of students “cheat the system”
• Despite the availability of the answer, the overwhelming majority of students will make an earnest attempt at completion
• Methods: award small amount of points for completion and assign reasonable amount of work
