Explicitness of deductive instruction and L2 development
A study on the Spanish imperfect subjunctive
Sergio Adrada-Rafael | Fairfield University
This study investigated the effects that different types of instruction varying in explicitness had on 88 intermediate-level Spanish
learners’ development of the imperfect subjunctive on a reading task. Participants were randomly assigned to one of 3 experimental conditions that
differed in their degree of instructional explicitness (+/− deductive). One condition (+Deductive) received a detailed grammar explanation prior to
task; a second condition (−Deductive) received a hint about a new target form present in the reading task, and the third condition (Baseline) was not
presented with any grammar information or hint. The study consisted of 3 sessions, following a pre/post/delayed computerized test design with 2 weeks
between sessions. Results showed that the −Deductive condition performed as well as the +Deductive condition immediately and 2 weeks after treatment
for both Interpretation and Controlled production tests.
