DYNAMIC INTERPLAY BETWEEN PRACTICE TYPE AND PRACTICE SCHEDULE IN A SECOND LANGUAGE THE POTENTIAL AND LIMITS OF SKILL TRANSFER AND PRACTICE SCHEDULE

To investigate the skill transfer and the effects of practice schedules in the learning of second language syntax, 129 intermediate-level English learners were divided into six groups, based on practice format (input vs. output practice) and practice schedule (blocked vs. interleaved vs. hybrid [blocked + interleaved]). Analyses revealed that the learners tested on the skill they had practiced outperformed those who were tested on the nonpracticed skill. This pattern was particularly pronounced in comprehension processing speed and production accuracy. Moreover, hybrid practice facilitated skill development more than blocked or interleaved practice alone. Furthermore, a dynamic interplay was detected among practice format, schedule, and learners' prior knowledge. Hybrid practice led to the least transfer from receptive skills (gained through input practice) to productive skills. Unlike interleaved practice effects, the effects of blocked practice on comprehension speed were more susceptible to learners' prior processing speed.
