You find the app program in this link : https://www.robotique.site/tutorial/c... The objective of a multiple choice quiz mobile application developed using MIT App Inventor is to create an interactive and educational tool that allows users to test and improve their knowledge through a series of questions with multiple answer choices. This type of application combines learning, self-evaluation, and mobile technology in a simple, user-friendly format. The main goal is to: 1- Test User Knowledge : The app presents a set of questions on a specific topic (e.g., science, math, language). Each question has several answer options, but only one correct answer. 2- Enhance Learning Through Practice : By interacting with the quiz, users reinforce their understanding. Immediate feedback helps correct mistakes and retain information. 3- Offer Instant Scoring and Feedback : The app calculates the user's score automatically. It provides feedback on whether the selected answers are correct or not. 4- Promote Self-paced Learning : Users can take the quiz anytime and anywhere using a smartphone or tablet. They can move at their own pace using buttons like Next, Validate, and Reset. 5- Encourage Digital Skills Development : Building the app in MIT App Inventor teaches logical thinking, problem solving, and basic programming. It introduces users to key programming concepts such as variables, lists, procedures, and events. 6- Provide a Reusable Template : The same structure can be reused for different subjects by simply updating the list of questions and answers. Teachers and students can customize it to fit educational needs.
