Results showed that the experi-mental group learned more words than the control group. In another study, Perez’s (1981) work with third graders revealed that the experimental group receiving 20 min of daily oral language instructionv on word meanings, over the course of about 3 months, showed significant improvements on word learning over the group receiving regular instruction (i.e., reading text and answering questions). Thethird vocabulary study (Ramirez, 1986) also focused on third-grade Spanish speakers.
