摘要：The present study aimed at investigating whether two types of computerized techniques, namely Computerized Input Enhancement (CIE) and Computer-Assisted Marginal Glosses (CAMG) had any significant impact on vocabulary recall and retention of a group of Iranian EFL learners. After designing two programs for the purpose of the study, the CIE group was exposed to texts in which the words were blinking in a different color while for CAMG group the new words were presented in the margins of the texts along with relevant pictures whenever the learners moved the cursor. Subsequently, nine passages with appropriate readability scores were selected and uploaded for further use. Next, 47 pre-intermediate level language learners in two intact classes were selected from a language school in Tehran, Iran and were randomly assigned to two experimental groups. Based on Vocabulary Knowledge Scale (VKS), 42 unknown words from the reading texts were identified. During the treatment, the participants were expected to read the texts and check the meanings of the unknown words. After the treatment, the participants took two posttests (immediate and delayed), the results of which were analyzed through repeated measures ANOVA. A statistically significant difference between the two groups showed that CAMG outperformed CIE.
