Studying the Effect of Retrieval Direction during Reading on Productive and Receptive Knowledge of Vocabulary

Retrieval tasks provide learners with an opportunity to focus both on meaning and on form. There are four different retrieval directions. The present study aimed to identify the optimal direction of recall type retrievals during reading and to investigate the outcomes of each one. Forty-eight intermediate EFL learners took part in the study. One of the experimental groups was provided with the productive retrieval version of the reading text, and the other experimental group with the receptive retrieval version. A Posttest was conducted in both productive and receptive directions for all the groups. Delayed posttests were administered two weeks after the treatment without prior notice to evaluate the time effect on participants' performance in each group. The results showed that there was a statistically significant difference in participants' performance in immediate and delayed posttests based on the method of retrieval. Further explanation of the effect of each retrieval direction on immediate and delayed posttests has been presented.
