Rich, contextualised and comprehensible input is far more effective in bringing about morpheme acquisition and vocabulary development in learners.
“the study findings support the argument that rich, contextualised and comprehensible input is far more effective in bringing about morpheme acquisition and vocabulary development in learners (Stephens, 1977;Krashen, 1989;Khan, 2022).”

“In particular, it is believed that learners may encounter more unknown words when reading independently, which brings opportunities to infer the unknown words in specific contexts and thus learn their meanings (Krashen, 1989).”

“Second, it is assumed that language is acquired by understanding messages and, consequently, that language learners should be exposed to comprehensible input (Krashen, 1989), an assumption that is central to Krashen’s Input Hypothesis (IH; 1981, 1982, 1992).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
