Action-Based Teaching and Learning refers to an approach that puts the learner’s agency (or ability to act) at the center of attention. Language is not seen as an object (a set of grammar rules, vocabulary), but as a form of human action. Moreover, the processes of language learning involve the mind, body, emotions, and all the senses. In this presentation, content-based, task-based and project-based learning are all construed as approaches that put the learner’s agency at the center. In addition, form-focused or grammar teaching can also be conducted in an action-based manner, in which linguistic action is future-oriented and not past-oriented, and success-driven rather than correctness-driven. Examples of classroom tasks illustrating an action-based approach will be given.
