Mobile application for showing that behind the blocks within block programming there is code

Abstract: Scratch is a block programming language which introduces beginners to programming. Instead of code the user has access to a set of blocks with text and icons, explaining how the block will affect the program that is written. The connection between one block and the corresponding code can be hard to understand for the beginner. The goal of this project is therefore to develop a user-friendly, flashcard-based mobile application to show the target group of 8- to 16-year-olds that behind every block there is code. The application is developed in TypeScript, using React Native as framework and the developer tool Expo for setting up and publishing of the application. The final application consists of 6 different screens; a starting screen, an information screen, a menu, a submenu, an "under development"-screen and a flashcard view. The user can navigate between the screens and by choosing a specific block the flashcard view displays a flashcard with the block and the corresponding translation in Python. The goal of the project is fulfilled, and with a testing group it is also confirmed that the application is user-friendly. Although the goal is achieved, the conclusion that the step between block programming and syntax is hard can be drawn, with difficulties in translating the blocks appearing along the way.
