Vocabulary Is it productive for a teacher to spend her time teaching vocabulary and reinforcing it with follow-up activities?
Set-Up • 2 groups of student • Each group took the same pretest, covering 20 words. • All words came from the book “A Dolphin Named Bob.” • Both groups read the same book over 3 weeks in our 40 minute Title 1 block that met every-other-day.
Instruction • We followed a DRTA model, which divided the book into 3 stops. • I pre-taught 10 words to one group and the other 10 words to the other group. • The ten taught words were defined before reading and examples provided. • We alternated between oral and silent reading.
Follow-up Instruction • We spent about 5 minutes playing reinforcement games. Examples include: • Thumbs up, Thumbs Down • Applause Please • Sentence Completions • Have you ever?
Post-Test • Immediately after the unit, I gave a post-test. • After about a 2 week delay, I gave a second post test to measure retention over time. • Both post tests were identical to the pre test.
Findings • A statistical analysis showed that there was no difference between the pretest scores and the 2 post test scores for the words that were not taught (in-context exposure only). • There was, however, a difference between the pretest and each of the 2 post test (immediate and delayed)
Conclusions • It is worth the time to teach select vocabulary before reading. • Students showed increased word knowledge even after a delay in time. • Decrease from immediate post test to delayed post test is also of interest, and could provide follow-up opportunities. • I’m interested to see what would happen if students were encouraged to use learned vocabulary in their writing.
