Dynamic Assessment: A Humanistic Approach of Learners ’ Writing Proficiency from a Vygotskian Perspective

Abstract. “Through others, we become ourselves”. Vygotsky (1978). Dynamic Assessment which stems from Vygotsky’s ideas, challenges the conventional and traditional views on teaching and assessment by arguing that instruction and assessment should be unified. The present study is an investigation of a DA-based instruction of L2 writing proficiency. For this purpose an OPT (Oxford Placement Test) was given to a total of 80 Iranian EFL learners. Then, 40 of them who were considered as intermediate learners were selected for the purpose of the study. The participants were randomly divided into two groups i.e. an experimental group and a control group. Both groups were pretested prior to the study; the participants underwent a static and a dynamic assessment. Then, the experimental group received the treatment in the form of DA-based instruction (i.e. aided instruction such as prompting, cueing, explaining and mediating within the assessment) for ten sessions while the control group received a normal practice of writing proficiency (non-DA instruction and assessment). After ten sessions, both groups were post tested i.e. once again, the participants underwent a static and a dynamic assessment. Then the results of the posttests were subjects of statistical analysis (independent-samples t-test). The results indicated that the experimental group did better than the control group and there is a significant difference between the mean scores of the experimental group who were exposed to a DA-based instruction and the control group who received a norma
