What does "task complexity" refer to in language learning?

"Task complexity" in language learning refers to the degree of difficulty associated with the tasks learners are asked to perform, which, in turn, influences their use of the language. This concept is crucial as it affects how learners engage with language in practical contexts. When tasks are complex, they challenge learners to employ higher-order thinking and language skills, which can enhance their ability to use the language more flexibly and effectively.

As tasks become more complex, they typically require learners to integrate various language skills—such as speaking, listening, reading, and writing—while also managing the cognitive load involved in understanding and negotiating the task requirements. Thus, task complexity is not merely about the inherent difficulty of a task but rather how those challenging elements can encourage greater language practice and acquisition.

This understanding helps educators design learning activities that are appropriately challenging for their students, facilitating better language uptake and retention through engaging, real-world tasks that reflect varying degrees of complexity.
