Investigation of the Effect of Badges in the Online Homework System for Undergraduate General Physics Course

Badges in education are an increasingly popular phenomenon, and a variety of questions exists as to the abilities and effectiveness of badges. In this study, the effect of digital badges within a Moodle-based online homework system was studied for an undergraduate general physics course at a large research-based university in northeast Taiwan. One hundred and sixty-two participants from two General Physics sessions were involved in this study and divided into two groups through self-selected options. Sixty-eight students in the treatment group could use digital badges in the online homework system, being able to earn one badge per assignment for turning their assignments in earlier than the assignment deadline, while the other students in the control group had no digital badges in the online homework system. The results showed that students in the treatment group turned in their assignments earlier than students in the control group did, and this difference was statistically significant. Further analysis showed that students in the treatment group spaced out their assignment practice more than students in the control group did, and the difference was statistically significant. Additionally, students in the treatment group actively attempted to earn badges, as there was a statistically significant increase in the number of badges earned by students in the treatment group over those in the control group. Based on a questionnaire given to study participants towards the conclusion of the study, the study found that students' perception of badges was positive. These findings corroborate earlier findings by other researchers that badges can be used to motivate specific behaviors in students whilst requiring minimal changes to the course structure. However, further corroborating earlier research is the finding that badges may not be particularly useful to motivate students towards challenging tasks. An earlier study of this course in a preceding academic year found that students are appreciative of the online homework system, and it appears from this study that the primary function of badges within the system is to enhance the experience of students, as well as to motivate timely engagement with assignments.
