| I have designed 2 web based code playgrounds that you may find interesting. https://try.gambitscheme.org is a playground for the Scheme language (specifically Gambit Scheme). It has a REPL and a code editor that saves files in the browser local storage. It also has a tutorial for learning the basics of Scheme. https://codeboot.org is a playground for Python (there's an old version that supports JavaScript and we may resurrect it at some point). It was specifically designed as a simple IDE to teach programming to beginners and is in use at the Université de Montréal. Aside from the simple and intuitive UI, it has two important features for teaching: 1) Fine granularity single-stepping of Python code to help teach students how the computer goes about executing the code. It displays a bubble containing the variables in scope and their values. 2) It can bundle programs and the current state of execution in a URL that can be embedded in documents (HTML, PDF, PowerPoint, Keynote, etc) so that coding examples can be executed by the students in a single click. It also allows students to create simple web apps that require no installation and can easily be shared with others (because the URL contains all the relevant code of the app). You will find examples of this feature on the following pages: https://codeboot-org.github.io/presentations/ https://codeboot-org.github.io/cegep/ (in french, but just click on the images) |
