Presenting and investigating the effect of a local model of dynamic assessment in diagnosing and removing learning difficulties of high school students in productive skills

Dynamic assessment is a new approach toward testing which is deeply rooted in a variety of theories and therefore attracted researchers in recent decades. However, most of the researches conducted in the field have been in experimental settings and few of them, if at all, have studied its applications in real educational setting.Thus,aimed at diagnosing and removing learning difficulties of Iranian high school students in productive skills of English, the current research was an attempt to present and explain a local model of dynamic assessment and then compare its results against a standard model. The findings showed that the local model is not only able to prognosticate language problems but also to propose a local inventory of mediation for removing them. Besides, the results of a post test only control group design through analysis of variance showed that the participants which used the model outperformed both control group and the one in standard dynamic assessment approach. These findings have implications for teachers, syllabus designers and educational decision makers.
