Dynamic Assessment in Second Language Education: A Systematic Review from Theoretical Foundations to Practical Implementations

Abstract

Dynamic Assessment (DA), fundamentally rooted in Vygotsky's Sociocultural Theory (SCT), has progressively evolved into a transformative and highly effective criterion within the broader landscape of second language education. By seamlessly integrating assessment and instruction into a unified, cohesive process, DA challenges traditional testing paradigms. This comprehensive review synthesizes existing empirical research to meticulously trace the developmental trajectory of DA, transitioning from a purely theoretical framework to highly practical implications across diverse English as a Second Language (ESL) and English as a Foreign Language (EFL) contexts. Based on a rigorous analysis of contemporary studies, this paper systematically explores the underlying operational mechanisms of DA in accurately diagnosing and expanding the learner's Zone of Proximal Development (ZPD). This is achieved through various pedagogical strategies, including targeted teacher intervention, collaborative peer interaction, and the deployment of cutting-edge AI-driven technologies. The synthesized findings conclusively demonstrate that direct teacher mediation yields the optimal pedagogical effect, particularly in enhancing macro-level writing proficiency and translation accuracy. Conversely, peer mediation serves as an effective catalyst for promoting sustained learner autonomy and collaborative problem-solving skills. Furthermore, the strategic integration of Computerized Dynamic Assessment (CDA) alongside artificial intelligence provides a highly feasible and innovative solution to the persistent scalability challenges traditionally associated with DA implementation. Ultimately, this paper argues that a modality-integrated DA model, carefully adapted to specific instructional objectives, will significantly help educators and researchers grasp the future direction of second language assessment methodologies.
