Comprehensible Output
From RevTK
o+1 or “output plus one” refers to comprehensible output, from Merrill Swain's Output Hypothesis, which was originally posited in reaction to the dominance of Stephen Krashen's Input Hypothesis. The Output Hypothesis suggests the language learning value of pushing learners to engage in production tasks just beyond their competence level. It is often referred to by linguists, such as Paul Nation, to promote the equal need for both meaning-focused input and output to fully acquire a language.
