The topic of electric fields is often confusing to many students in introductory physics courses. This study details the evaluation of two new technological tools, an online game and simulation, that were developed by our research group. To evaluate the efficacy of these tools, we compare the learning gains and technology anxiety of students who have interacted with the game, simulation, and a video playlist in a controlled environment. The results showed that no individual learning tool was significantly more effective than the others; however, gains from pre- to post-diagnostic were significant across all three groups. It was also found that students vastly preferred learning about electric fields via the video playlist over the game and simulation. Additionally, the study provides insight into the further development of our technological tools through student feedback. Students commonly requested more guidance and instruction from the two tools.
