Interactive Quizzes as HTML Widgets.

rquiz

rquiz provides interactive quizzes as HTML widgets for R Markdown, Quarto, and Shiny applications. It offers three quiz types: a single question with instant feedback (singleQuestion), a multi-question quiz with navigation, timer, and results (multiQuestions), and fill-in-the-blank cloze exercises (fillBlanks). All quizzes support single-choice and multiple-choice modes, customizable styling, and multilingual UI.

I developed this package for my Data Science in Biology modules at the University of Hamburg, where I have been using and testing it with students since 2020 in HTML-based lecture slides (see e.g. fill-in-the-blank quiz and multi-page quiz in my Data Science 1 course).
