working memory

Motivation and affect as two salient variables in L2 development are no longer seen as the stable individual difference factors they were once believed to be. Influenced by process-oriented approaches and by increasing understanding of how the complex dynamic system theory (CDST) works, researchers have been emphasizing the holistic, non-modular, dynamic and changeable nature of motivation and affect to-date. Accordingly, this study utilized the principles underlying the CDST perspective to examine the interrelationships between Iranian EFL learners’ motivational and affective factors mediated by working memory and gender over an academic semester. To this end, 445 pre-intermediate male and female students completed the motivation questionnaire and L2 Enjoyment Scale four times with one-month intervals during an academic semester and Working Memory Scale once in the beginning of the term. Relationships that emerged indicated both motivational and affective stability and fluctuation over a semester of instruction at one month intervals. The findings also illustrated how these factors are inseparable from students’ learning context. Implications of study and directions for further research were also discussed.

This study investigates the impact of computerized dynamic assessment (C-DA) on grammar learning among Iranian EFL learners, focusing on the moderating role of working memory (WM). A nonrandomized pretest-posttest control group design was employed, with 60 male learners aged 17 to 18 divided into experimental and control groups. The participants were assessed using the Oxford Quick Placement Test (OQPT) to determine language proficiency and a researcher-made test to measure knowledge of past perfect tense. The intervention involved C-DA sessions conducted via the Google Meet platform for the experimental group, while the control group received traditional teacher-fronted lessons. Results from independent-sample t-tests and one-way between-groups ANOVAs revealed a significant improvement in grammar learning among the experimental group compared to the control group. However, no discernable difference was found in the performance of high and low WM learners in response to C-DA. These findings highlight C-DA's potential as a practical instructional approach for grammar learning in EFL contexts. They underscore the need for further research to explore its utility across different learner profiles.
