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.

In recent years, dynamic assessment and positive psychology have attracted the attention of many researchers. This phenomenological study explores Iranian intermediate English as a Foreign Language (EFL) learners' perception of academic buoyancy, reflective thinking, and academic resilience in response to dynamic assessment. Data were gathered through narrative inquiry, observation, and focus group discussion involving 18 intermediate EFL learners at a language institute in South Iran. Member checking, peer debriefing, and audit trail were used to ensure the credibility and dependability of the instruments. Thematic analysis of the qualitative data revealed that dynamic assessment positively influenced learners' academic buoyancy by providing tailored scaffolding and support, fostering resilience in the face of academic challenges, and enhancing reflective thinking abilities. These findings suggest that integrating dynamic assessment techniques into language teaching practices contributes to students' adaptive coping mechanisms and ability to navigate academic setbacks, enhancing their academic success and overall well-being. The study underscores the importance of incorporating dynamic assessment approaches to cultivate resilient and empowered learners within EFL settings. This study contributes to understanding dynamic assessment's role in fostering academic resilience and reflective thinking in language learning contexts. The implications of the study are discussed.

This study investigated the interplay of working memory capacity and language proficiency in the context of vocabulary acquisition through word-focused tasks. The involvement load hypothesis served as a theoretical framework, positing that the degree of cognitive engagement influences lexical learning outcomes. A total of 100 EFL learners participated in this study. They were divided into distinct groups based on varying levels of working memory capacity, language proficiency, and aspects of working memory (phonological short-term memory and executive working memory). The participants engaged in receptive and productive vocabulary tasks under different experimental conditions, including reading-only, reading plus blank-fill, and reading-plus production. The results revealed intricate relationships between working memory capacity, language proficiency, and vocabulary acquisition. While the efficacy of the hypothesis varied across conditions, its predictions were influenced by the nuances of individual cognitive capabilities and language competence. Learners with higher proficiency levels acquired more lexical items, both receptively and productively.  Although the difference with the phonological short-term memory was not significant, executive working memory was more facilitative of lexical gain. Additionally, the role of input modality in shaping vocabulary learning outcomes was highlighted. That is, reading plus production and blank-fill tasks resulted in more lexical gain than reading-only tasks.  The study contributes to the theoretical understanding of vocabulary acquisition by underscoring the complex interplay of cognitive processes and language factors. These insights hold implications for foreign language pedagogy, guiding educators in crafting more effective interventions for enhancing both receptive and productive lexical knowledge.
