The other half, who read a “Beowulf” graphic novel, spent about two hours. Both groups took the same 25-question multiple-choice test. Students who read the traditional text scored 81 percent on average compared with 75 percent for those who read the graphic novel. The presenting educators wondered if the few points difference on the test were worth the extra time — “would that time be better spent doing other things?” This is exactly what worries some observers about graphic novels in the classroom — and about the increasing and myopic focus on testing to measure learning.
