Interactionist Model

Over the past decades, writing assessment research has been concentrating on alternative methods with a social-oriented view of assessment, including dynamic assessment (DA). Given the lack of research juxtaposing the interventionist and interactionist DA frameworks in the area of narrative writing, this study sought to compare the effectiveness of Brown’s graduated prompts model vs. Poehner’s model in the development of one-paragraph narrative essays in terms of grammatical accuracy. The study followed a quasi-experimental design, with 15 Iranian EFL learners selected via convenient sampling from among the female students of a language institute in Tehran. The participants were then randomly divided into three groups: Interventionist group, in which mediation was based on Brown’s model in the sandwich format; interactionist group, where mediation was done using Poehner’s model in the cake format; and non-dynamic assessment (NDA) control group with no mediation involved. The research consisted of three pilot sessions and eleven sessions as the main phase. To analyze the data, both descriptive and non-parametric inferential statistics were run. The results conceded the superiority of both DA approaches to NDA, whereas no significant difference was observed between the two DA groups in their general performance on narrative tasks. However, the analysis of the number and types of required mediational moves over the DA sessions indicated the superiority of the interactionist model to interventionist framework in the development of grammatical accuracy in narrative paragraphs. The study offers some theoretical and pedagogical repercussions for educators, curriculum designers, and L2 teachers.

In recent years, the importance of willingness to communicate (WTC) in second language acquisition has gained considerable attention, as it is a crucial factor influencing learners' language use and overall communicative competence. Understanding how various instructional methods can enhance WTC is vital for improving EFL education. This study investigated the comparative impacts of interventionist and interactionist dynamic assessment models on the WTC among 75 Iranian intermediate EFL learners. Participants were divided into two experimental groups (EG1 and EG2) and one control group (CG), with a total of 16 treatment sessions delivered over a semester. Both experimental groups received dynamic assessment interventions, with EG1 utilizing the interventionist model and EG2 employing the interactionist model. The results revealed that both EGs significantly outperformed the CG in enhancing WTC; however, no statistically significant differences were found between the two experimental groups. This study contributes to the understanding of how different dynamic assessment approaches can effectively foster learners' WTC in English. The findings suggest that educators can adopt either dynamic assessment model to improve WTC among EFL learners, emphasizing the need for ongoing research into optimal assessment strategies in language education.
