Interventionist Dynamic Assessment

The current study investigated the impact of an interventionist model of dynamic assessment, using a repetitive process of pretest-teach-posttest design, on Iranian EFL learners’ reading comprehension and classroom engagement. To this end, 40 intermediate participants were selected through convenient sampling from among the English majors of a university in Kerman, Iran, and assigned to two control and experimental groups, each including 20 students. Then, during 4-month period, the experimental group was exposed to reading comprehension class, using an interventionist model of DA, while the control group did not receive ant dynamic assessment program. At the end of the treatment, the participants’ scores on the pretest and post-test were statistically compared. The obtained results revealed that the experimental group significantly outperformed the control group on the scales of reading comprehension skill. A change was also observed in the classroom engagement of the experimental group, but not for the control group. Indeed, the results showed that dynamic assessment can boost participants' performance in a practical and effective way, not only in terms of reading performance but also in terms of motivating more classroom engagement among EFL learners. This finding has implications for teachers to design more efficient courses which are the ultimate goal of education.  

Dynamic assessment (DA) is an effective strategy to combine teaching and testing and it is even more enjoyable through digital devices such as computer and moblie devices. The purpose of the current study was to investigate whether the effect of interventionist dynamic assessment through WhatsApp, Bigbluebutton, and face to face classes had significant impacts on English as a foreign language (EFL) learners’ learning of grammar. The participants of this quasi-experimental study were seventy-five male intermediate EFL learners studying English in one of the English language institutes in central Iran. Three intact pre-intermediate level classes were chosen based on non-random convenience sampling and assigned to the three groups of WhatsApp, Bigbluebutton, and traditional group. The instruments that were used in this study were the Oxford Quick Placement Test (OQPT) and a multiple-choice grammar test. Over the course of six sessions, all three groups received interventionist DA strategies in teaching countable and uncountable nouns and determiners. The results of statistical data analysis showed that all three groups had significantly progressed over the study since there was significant difference between the pretest and posttest scores of each group. However, no statistically significant differences were found among the three groups’ means on the posttest of grammar. The findings have implications for language teachers and researchers of second language acquision.

The present study explored the effects of interactionist Dynamic Assessment (DA) and age on the writing accuracy of IELTS candidates. This research investigated the existence of an interactional effect between the age of learners and the type of treatment they received. First, 140 IELTS candidates were split into two age groups, adult and young. Each group was divided into two equal smaller groups, randomly assigned to two types of DA. All four groups took a writing pre-test. After a nine-session treatment of interactionist DA in study groups and interventionist DA in control groups, all groups took a writing post-test. The data collected during the post-test were analyzed by two-way ANOVA and compared with the pre-test data. The findings showed that implementation of interactionist DA significantly improved the learners’ writing accuracy while the learners’ age had no significant effect on their writing accuracy. With respect to the study findings, EFL teachers could use interactionist DA to enhance the accuracy of learners' writing skills by providing more opportunities for the learners to interact.

According to sociocultural theory, dynamic assessment (DA) merges instruction and assessment. This study attempted to compare the effects of interactionist versus interventionist DA on the writing fluency and complexity of adult versus young IELTS candidates in an international language school in Tehran with the age range of 15-48. One hundred and forty students (90 males and 50 females) who had enrolled in the IELTS preparation course in the spring of 2021 participated in this study. The study participants were divided into four groups namely, young interactionist, young interventionist, adult interactionist, and adult interventionist. The participants in all groups were homogenized based on the result of their performance in a standard version of Preliminary English Test (PET). During the eight-week treatment period, the interactionist groups were given writing tests followed by the instructor’s feedback and guidance, while the interventionist groups received instructions and were given writing test samples without qualitative feedback. The pre-test and post-test comparisons among the four groups by Two Way ANCOVA showed that both young and adult individuals in the interactionist groups had a significant improvement in their writing performance compared to those in the interventionist group. In addition, the study revealed the significant impact of interactionist DA vs. interventionist DA on both young and adult participants' scores in both writing fluency and complexity post-test. Likewise, the results showed no statistically significant interaction between the type of assessment and the candidates’ age. The study presents pedagogical implications for teachers, students, and IELTS preparation program designers.
