Embarking on the development of HydroAR, an app designed to shed light on the complexities of the water cycle, presented a myriad of challenges and opportunities. The goal of enriching students’ understanding became my focus, and the true test unfolded within the classrooms of Podar International School, Latur. I am sharing a firsthand account of our initial Usability testing and A/B testing experiences, outlining the challenges, celebrating victories, and reflecting on transformative moments throughout the process.

Day 1: Establishing a Baseline: The journey began with the objective of assessing students’ understanding. Conducting a carefully crafted water cycle test for both class 4 and class 5 students exposed that, on average, class 4 students scored 3.45 out of 10. This indicated a specific need for support among class 4 students due to their limited knowledge of the water cycle.

Day 2: User Interaction Analysis: Selecting class 4 students to participate in using the HydroAR app, I conducted observations to identify usability challenges. A subsequent in-depth test with 10 students revealed specific pain points, leading to the introduction of voice functionality aimed at enhancing user engagement.

Day 3: Expanding the Test Pool: Scaling up testing efforts to include 20 additional class 4 students and introducing A/B testing with 5 students allowed me to collect more data. Positive feedback from the survey indicated a 3-point increase in satisfaction. The updated version of the app, with an average completion time of 5 minutes and 9 seconds, achieved an improved score of 4.7 out of 8.
