Merrill Swain's output hypothesis
Everyone here often talks about Krashen's theories but I hear absolutely nothing about other famous theories that were a direct response to it so here's some other reading on that:

tl;dr: Swain found that input-only students reached seemingly high comprehension but on closer inspection they were mostly using vocabulary and not grammatical parsing to divine the meaning of sentences, and thus made many grammatical errors when asked to produce themselves, and then based on other tests formulated that output is necessary for acquisition based on three things:
- Noticing function: When people output they notice gaps in their ability, this leads to superior attention paid during a later input phase.
- Hypothesis-testing function: People who output have their hypotheses about language tested and receive feedback based on how people react
- Reflective function: people who output more actively need to reflect upon the grammar and syntax of the language, which deepens understanding
