The comprehension hypothesis: We acquire language when we understand what we hear or read: "skills" (grammar, vocabulary) are the RESULT.  (win-win)
Rival: Skill-building hypothesis: we first learn rules consciously, practice them in ouput, get correction. Rules become automatic; someday we can use the language. (lose-lose)

Evidence for the Comprehension Hypothesis
Method comparisons:
1 beginning foreign language: 17 studies published in IRAL, MLJ, FLAnnals, Hipania
2 sheltered: 5 studies, in TESL Canada, CMLR, Language Learning, SSLA
3 sustained silent reading
Comprehensible input-based methods versus traditional methods.

Case Histories: Vaupes River, Armando, Lomb Kato (Krashen, S. 2014. Case Histories and the Comprehension Hypothesis. TESOL Journal (www.tesol-journal.com), June, 2014)

Explains best use of the first language: When it makes input more comprehensible; eg success of bilingual programs.  (McField, G. & McField, D. 2014.  The consistent outcome of bilingual education programs: A meta-analysis of meta-analyses. In G. McField (Ed.) The Miseducation of English Learners. Charlotte: Information Age Publishing. pp. 267-299.)

RIVAL HYPOTHESES
Grammar instruction: Strict limits on the learning, use of grammar: Know the rule, think about correctness, time: (Krashen, S. 1982. Principles and Practice in Second Language Acquisition, www. sdkrashen.com).
Studies claiming effect of grammar obey these conditions. (Krashen, S. 1999. Foreign Language Annals 32(2): 245-257; Krashen, S. 2003. Explorations in Language Acquisition and Use: The Taipei Lectures. Portsmouth, NH: Heinemann.)

Error correction: obvioius effect only when conditions for grammar are met: focus on simple rule,  thinking about correctness, tme. (exclude revision studies, immediate response)
{Truscott, 2007 The effect of error correction on learners' ability to write accurately. Journal of Second Language Writing 16: 235-272. Truscott, J. (1999). What’s wrong with oral grammar correction. Canadian Modern Language Review, 55, 437–456.)

Ootput
1.     No correlation between amout of spealing, writing and competence 
2.     Not enough output (Krashen, S. 1994. The input hypothesis and its rivals. N. Ellis (Ed.) Implicit and Explicit Learning of Languages  Academic Press. pp. 45-77.)
3.     Comprehensible output? Krashen, 2003, Explorations (Heinemann): not enough, no expirical stupport; acquisition happens without it, pushed output is uncomfortable
4.     Adding writing to reading does not increase the effect (Mason, B. 2004 The effect of adding supplementary writing to an extensive reading program. IJFLT 1(1), 2-16
5.     What writing is for.
