EVIDENCE FOR
EFFECTIVENESS OF AL
“Active learning increases student performance in
science, engineering, and mathematics”
Meta-analysis of 225 studies of AL:
• Increases exam scores
• Decreases failure rates

DISCUSSION:
TRANSFORMING THE CLASS
• What more do you need to know?
• What questions/issues does this raise?
• What should we do next?
• Other questions/thoughts/ideas?
II: KEY FEATURES
1. Tight integration of video, questions, class
activities, expectations
1. Judicious use of low-stakes “ungraded” questions
How Useful Were These in Preparing for the Exams?

“UNGRADED” PROBLEMS
Must get correct but:
• After first try, they can click “Show answer”
Goals:
• Low stakes => more exploration
• They might not “get it” from on-line materials
• Wrong answer = learning opportunity (≠ failure)
Risks:
• Slacking
• Potential course collapse…
Consider this student’s log entries for one problem:
01:24:08 – loaded problem 4_2
01:24:11 – submitted incorrect answer to 4_2
01:24:12 – clicked 4_2’s “Show Answer”
01:24:26 – submitted correct answer to 4_2
How would you categorize this sequence?
A. Never tried problem 4_2 (N)
B. Tried 4_2 but never got it correct (I)
C. Got 4_2 correct before looking at answer (C)
D. Got 4_2 correct after looking at answer (P)
E. Never got 4_2 correct even after looking at answer (W)

“WAIT ‘TILL NEXT YEAR”
• Show students the data
• Tighter integration
• Different types of before class problems
• Core – simple but cannot peek (2 tries)
• Challenge – harder and can peek (infinite tries)
