Do low-skilled college algebra students learn more from completing online homework than textbook homework? To find out, researchers studied 75 low-skilled college algebra students at a large community college. Some of the students completed their homework using a textbook. The rest completed similar homework using an online homework system developed by the textbook publisher. The students’ mathematical achievement was measured by a common final exam. The researchers concluded that low-skilled college algebra students learn more from completing online homework than textbook homework.
