Vocabulary learning needs special strategies in language learning process. The use of dictionaries is a great help in vocabulary learning and nowadays the emergence of electronic dictionaries has added a new and valuable resource for vocabulary learning. The present study aims to explore the influence of Electronic Dictionaries (ED) Vs. Paper Dictionaries (PD) on vocabulary learning and retention of Iranian EFL learners. Seventy college students formed the participants of the study. Before the treatment, a Preliminary English Test was used for assessing the participants' homogeneity. The participants were assigned to Electronic Dictionary (ED) group and Paper Dictionary (PD) group. The treatment lasted for 15 sessions. Eighty-eight new target words were selected in order to be taught in this study. The ED group participants were asked to use their mobile dictionary (Blue Dict dictionary), that include eight popular different dictionaries. The participants of the PD group used their ordinary Paper Dictionaries for finding the meaning of words. In order to check their short-term and long-term vocabulary learning, both groups took part in an immediate and delayed post-test respectively after the treatment. Based on the t-test results, the participants in ED group outperformed those of PD group. The overall results indicate that EDs can improve vocabulary learning.

The present study aims at investigating the influence of podcasts (POD) on language comprehension of Iranian pre-intermediate EFL learners. An Oxford Placement Test (OPT) was administered to 60 male and female university students. The participants were considered as pre-intermediate learners and were divided into two groups (one experimental group and one control group). During the fifteen sessions of the treatment, thirty podcasts were presented to the two groups. The experimental group received just the audio file of the POD, and the control group received a different treatment which was the transcript file of the same audio podcast file of the experimental group. The results of the t-tests revealed that there was no significant difference in language comprehension scores across the posttest between two groups. Based on the interview results after the post-test, all of the participants (100%) agreed that both audio and the transcripts (written texts) were useful for them and claimed that it is a good method of improving language comprehension.

Abstract-The present study aims at investigating the effects of extensive reading (ER) on language proficiency of Iranian intermediate EFL learners. A Preliminary English Test (PET) was administered to 106 male and female university students. The participants were selected as intermediate learners and were divided into three groups (one control and two experimental groups). During the ten sessions of the treatment, ten short stories (authentic and simplified) were provided to the two homogenous groups (two experimental groups). The first experimental group received authentic reading texts and the second experimental group received simplified reading texts, while the participants of the control group followed the ordinary reading course at the university. All three groups received post-tests administered after the treatment. The results of the t-tests revealed that there is no significant difference in reading scores across the posttest between two experimental groups. The results of ANOVA also revealed that there is a significant difference between the scores of the control group and experimental groups' participants. Based on the interview result after the post-test, all of the participants (100%) agreed that they had positive attitude toward extensive reading after participating in the treatment sessions. The study suggests, however, students' curriculum courses should include extensive reading texts in order to develop EFL language proficiency.
