摘要：Language assessment is the significant component of foreign language learning/ teaching. An aim of language assessment is to find about how much the process of education improves learners’ knowledge of the target language. One alternative to standardized testing, Dynamic Assessment derived from Vygotsky’s sociocultural theory offers a new insight into the field of assessment through integrating instruction and assessment. Dynamic assessment is a method of conducting a language testing to investigate and highlight the individual learner's possessed skills and potential development. The present study is going to display an overview of the importance of dynamic assessment in L2 learning, emphasizing the origins and principal concepts involved in the process. The study highlights the derivation of dynamic assessment from Vygotsky’s prominent sociocultural theory. Then it brings about an introduction to zone of proximal development the concept of which learner's cognitive development results through the application of dynamic assessment. Later the study discusses dynamic assessment in detail and introduces its differences with the traditional testing formats as well as introducing forms of dynamic assessment.
