Incidental vocabulary learning is often seen as superior to direct instruction on many occasions. Meanwhile, upon the emergence of the World Wide Web, second language (SL) learners have been introduced to 'podcasts' (recorded audio and video online broadcasts) which could be authentic sources of vocabulary learning. The relatively recent phenomenon of video podcast (vodcast) might be considered as a reliable complementary source of input to the written text or the audio track which are predominantly used to represent the platforms of SL instruction. To examine this assertion, three groups of Iranian EFL learners (n=63) were independently exposed to different modes of input (the reading text, audio track, and vodcast) during a series of classroom sessions under highly controlled circumstances. Immediate and delayed passive recall tests of vocabulary were administered to investigate their incidental gains. A multivariate analysis of variance revealed that both dependent variables (immediate and delayed recall) were significantly affected by the input modes. The post-hoc tests indicated no significant difference between the written and the audio groups while the vodcast group significantly outperformed the other two. The rich contextual clues made available by this audiovisual source seem to account for its superiority

This experimental study attempts to see whether incorporating supplemental podcasts into the blended module of second language (L2) vocabulary teaching and learning leads to better learning outcomes in comparison with other common teaching and learning methods as self-study and conventional. To that end, undergraduate students from Ahvaz Jundishapur University of Medical Sciences were summoned up via an announcement to take part in the study. Volunteers were homogenized via Vocabulary Levels Test (VLT) and were then randomly divided into three groups to learn English vocabulary items via three different scenarios during 32 sessions. The collected data from the participants’ answers to the attitude questionnaire and interview as well as the data from assessing their performance throughout the course were analyzed both descriptively and inferentially. The analysis of the data revealed that the podcast-mediated blended L2 learning scenario appeared as the most successful scenario in L2 vocabulary learning. Consequently, it could be concluded that providing miscellaneous practicing opportunities for students would facilitate learning process and contribute to learning improvement.
The Impact of Using Podcasts on Iranian Autonomous /Non-Autonomous EFL Learners’ Listening Comprehension Ability at Pre-Intermediate Level
The aim of the current study was to investigate whether Podcasts would have an effect on Iranian autonomous and non-autonomous EFL learners’ listening comprehension ability at pre-intermediate level. For this purpose, 60 Iranian pre-intermediate EFL learners at some Iranian institutes participated in the experiment of the study. Then they were divided into two groups based on an OPT and an autonomy questionnaire. The participants of each group were assigned randomly into two experimental groups (N=15) and two control groups (N=15). A pre-test was administered to the four groups of the study and then, the experimental groups received 5 sessions of teaching podcast. After the treatment, a posttest of L2 listening comprehension was administered to all groups of the study and finally the data were analyzed via a series of paired sample t-tests to see whether there is progress between the pretest and posttest scores of the groups, and a Two-way ANOVA was used to see the differences between posttests. The results revealed that Iranian autonomous and non-autonomous EFL learners’ listening comprehension ability got better after the treatment.
This paper reports an attempt to see if podcasting can be a valuable tool to improve English vocabulary learning and retention of Persian university students compared with traditional method of vocabulary teaching. Students have been randomly divided into two groups namely experimental and control group. In the experimental group, students are asked to produce podcasts collaboratively and students in the control group are asked to spend the same amount of time in a traditional class practicing vocabulary items. The analysis of covariance shows students in the experimental group significantly outperform students in control group in terms of both learning and retention of vocabulary items.
