This document discusses how to design language learning tasks that balance demands and support. It explains that tasks should have a clear purpose that makes sense to students. The demands of tasks should be analyzed, such as vocabulary or pronunciation requirements. Tasks can support learning through their structure or context. Well-designed tasks have demands that challenge students without being too difficult, while also providing enough support through the task framework or context clues. The goal is to create opportunities for growth by maintaining a productive balance between what is demanded of students and how the task supports their learning.
