q2 · i? · causal · r?

The chapter's introduction characterizes incidental acquisition through reading as a process that "is slow" and for which "there is no way to predict which words will be learned, when, nor to what degree." This is the authors' framing of the research literature, with no effect sizes reported.

"The process by which “incidental” acquisition through reading occurs is slow, however, and there is no way to predict which words will be learned, when, nor to what degree."

Discussion¶

Learner Variables¶

• Vocabulary — outcome: instruction changes it

Related Claims¶

• Vocabulary Knowledge Grows Incrementally With Repeated Encounters In Varied Contexts — the general claim this finding bears on, with the studies behind it
• Incidental vocabulary exposure produces reliable learning, but learners pick up only a small share of the unknown words they meet — related
• Single exposures yield partial word knowledge, and repeated encounters in varied contexts build complete word meaning (fast mapping then full mapping) — related
• The more often learners meet a word while reading, the more likely they are to learn it incidentally; a meta-analysis of correlational studies finds a moderate correlation — related
