SMILE (Server-Managed Interactive Learning Exercises) is a free online environment for creating interactive language-learning exercises. Teachers use templates to create activities, which are made up of individual items in formats such as multiple-choice, true or false, drag-drop matching, sentence mix, paragraph mix, cloze, and multiple-select. All of the content and the templates are stored on CLEAR's web server. Teachers have access to their content, and can add to it and edit their existing content. Documentation is available to guide teachers through the process of creating exercises.
