Which scenario best illustrates the effective use of active and passive…

Concept — A learner's vocabulary sits in two stores. Active (productive) vocabulary is the set of words the learner can retrieve and produce independently while speaking and writing. Passive (receptive) vocabulary is the larger set the learner recognises and understands while listening and reading, but does not yet produce. Vocabulary teaching works on the boundary between the two: input feeds the receptive store, and output is what carries a word across into the productive store.

Application — Judge every classroom scenario by the channel it places the learner in. Speaking and writing are the two productive channels; listening and reading are the receptive ones. Both stores are used effectively when words that were first met receptively are then demanded in production, because that demand is the only point at which a passive item can turn active.

Scenario by scenario

• Students repeat words after the teacher silently — the form is rehearsed inwardly; nothing is spoken or written, so the word stays in the receptive store.

• Students only listen to new vocabulary in lectures — listening is pure input; the word may be recognised later, but the learner never has to generate it.

• Students memorize word lists without context — a form is tied to a gloss in isolation, with no situation attached to cue its retrieval in speech or writing.

• Students use new words in conversation and writing — words met earlier through listening and reading (the passive store) are retrieved and produced in speech and text (the active store), so both stores are engaged and the passive item is converted.

Cross-check — Apply the observability test: a teacher can confirm that a word has become active only by hearing or reading the learner use it. Three of the scenarios leave nothing the learner produced to inspect; conversation and writing are what supply that evidence.

Hence the scenario in which students use new words in conversation and writing best illustrates the effective use of active and passive vocabulary.
