Vocabulary Guru (VG) is a custom-made mobile application (app) developed based on the task model and agile methodology via qualitative needs analysis. This investigation intended to assess the impact of VG on EFL learners’vocabulary recognition. First, 84 academic vocabularies were selected, based on their frequencies defined by the Corpus of Contemporary American English (COCA) (Davies, 2017) and the Academic Core Vocabulary Website (Davies & Gardner, 2019). From 141 university students, 60 intermediate female students were selected who were randomly assigned to an experimental group and a control group. The experimental group practiced the target vocabularies via VG, whereas the control group learned them via the conventional method. A vocabulary recognition test was developed and administered twice to both groups. Finally, two paired samples t-tests and two independent samples t-tests were utilized to estimate within and between-groups differences. The findings revealed that the experimental group outperformed the control group significantly. Manuscript profile

This paper is a descriptive-analytic study on the adpositional system in a number of northwestern Iranian languages, namely Taleshi, Gilaki, and Tati, based on Dryer’s typological approach. To this end, the correlation of verb/object order was examined with the adpositional phrase and the results were compared based on the aforesaid approach. The research question investigated the correlation between adposition and verb/object order in each of these three varieties. First, the data collection was carried out through a semi-structured interview that was devised based on a questionnaire including a compilation of 66 Persian sentences that were translated into Taleshi, Gilaki, and Tati during interviews with 10 elderly illiterate and semi-literate speakers, respectively, from Hashtpar, Bandar Anzali, and Rostamabad of the Province of Gilan for each variety. Then, the transcriptions were examined in terms of diversity in adpositions, including two categories of preposition and postposition. The findings of the study indicated a strong correlation between the order of verbs and objects with postpositions. More specifically, in most samples in all the varieties, objects precede verbs and postpositions are predominantly employed. Manuscript profile
