Programming is an important skill in the 21st century, but it is difficult for novices to learn. To help students practice and learn efficiently, the authors developed a mobile platform called Daily Quiz, which incorporated distributed practice theory. To evaluate the impact of distributed practice in programming learning facilitated by Daily Quiz, the authors conducted a between-subject experiment with 200 freshmen divided into two groups. Both groups received the same number of multiple-choice questions via Daily Quiz. However, the control group was encouraged to practice every 7 days, whereas the experimental group was encouraged to practice every 3 days. The results showed that this simple manipulation significantly improved the experimental group’s performance on final exams. Further analysis revealed that the experimental group of students achieved a higher rate of first-check correctness and tended to be more engaged in academic social interaction. Finally, a behavioral sequence analysis was adopted to compare the behavioral patterns of the two groups to investigate how distributed practice helped the students learn more efficiently.
