BitLanguage: A Java Language Learning App

This study undertook an investigation into a novel approach known as the Digital Assessment Proficiency Exam. The primary objective was to leverage this approach in the creation of a mobile application tailored to facilitate the comprehension of Java basics. Employing an iterative development model, the app's design and functionality were refined through a series of iterations. The efficacy of the developed app was evaluated by programming teachers, using the Great App Checklist. The obtained mean scores reflect a substantial validation of the app's design: 4.17 for its purpose, alignment, and ease of use, 3.83 for its pedagogical framework, 4.17 for personalization, and 4.28 for its overall contribution to the app ecosystem. This evaluation yielded consistently high scores ranging from 3.83 to 4.17, underscoring the remarkable efficacy of this study's outcome as an invaluable tool for learning Java.
