Task-based language learning (TBLL), also known as task-based language teaching (TBLT) or task-based instruction (TBI) focuses on the use of authentic language and on asking students to do meaningful tasks using the target language. Such tasks can include visiting a doctor, conducting an interview, or calling customer service for help.
Assessment is primarily based on task outcome (in other words the appropriate completion of tasks) rather than on accuracy of language forms. This makes TBLL especially popular for developing target language fluency and student confidence.
