Over the last decade, Mobile-assisted Language Learning (MALL) has led to an authentic and contextual language learning process across the globe (Kukulska-Hulme, 2009). It has played a pivotal role in language learning in general and vocabulary learning in particular as a building block of academic writing. The current study examined the effect of a mobile application (i.e. AWL builder) on academic vocabulary learning among sophomore university students in applied linguistics. The study also focused on measuring students' perceptions and problems in utilizing mobile-assisted applications in acquiring English academic vocabulary. Accordingly, using convenience sampling procedures the participants were divided into experimental (N =36) and control (N = 36) groups. The experimental group used a mobile application (i.e. AWL builder), while the control group used a traditional approach. Furthermore, to answer research questions academic vocabulary pre-and post-tests and a questionnaire were employed. The findings show that the AWL group showed prominent performance in academic vocabulary tests. The current study concludes that instructors should take into account mobile devices as useful supplementary tools to enhance L2 academic word retention and include them in regular language curriculum.

A correlational survey research design was utilized to investigate self-regulated Learning (SRL) and teacher-student interaction factors that had been realized to have contributive roles in EFL learners' academic success. A sample of 218 EFL learners (male = 102 and female = 116) was drawn with the aid of a prior sample size calculator for the structural equation models from 645 students. They were within the age range of 18-45 and were enrolled at Islamic Azad University, Tabriz Branch. The structural equation model (SEM) hypothesis testing procedure revealed that the teacher-student interaction directly and significantly influenced learners' academic accomplishments. Likewise, the obtained results indicate that the impact of the teacher-student interaction on EFL learners' academic achievement is mediated by the effects of SRL. Correspondingly, the obtained results indicate that the theorized model fits the data. The causal contribution of psychological factors, consisting of the teacher-student interaction and SRL, to EFL learners’ academic achievement was validated. The findings of this exploratory research have certain implications for classroom practice which are elaborated in detail in this paper.
