1. Introduction

This chapter introduces the concept of dynamic assessment and its integration of teaching and assessment. It discusses the theoretical basis for dynamic assessment, including Vygotsky's zone of proximal development. It also explains the motivation for using CiteSpace to conduct a visual analysis of dynamic assessment research to gain a more objective perspective. The study aims to visualize and analyze representative figures, research foci, important literature, and current trends in dynamic assessment research.

2. Methods

This chapter describes the use of CiteSpace to analyze bibliographic data and visualize the progression of dynamic assessment research. Data were collected from the Web of Science Core Collection, using the topic "dynamic assessment*" in psychology, education, and language categories, with a time period of 1990–2022. A total of 296 valid articles were obtained. Additionally, 28 articles from the China National Knowledge Infrastructure were included in the review.

3. Discussion

This chapter discusses the analysis of high-impact scholars in the field of dynamic assessment. Vygotsky is the most frequently cited author, with scholars such as Feuerstein, Lidz, Lantolf, and Poehner also making significant contributions to the field. These scholars have focused on the cultural-historical theory and sociocultural theory, as well as the application of dynamic assessment in L2 teaching. The research topics in dynamic assessment include the view of ability underlying DA, research objects of DA, and research focuses of DA, with a focus on early identification and intervention for children with developmental challenges.

4. Deep Discussion of L2 DA

This chapter discussed the mediational model of L2 Dynamic Assessment (DA), which includes interventionist DA and interactionist DA. It also covered research paradigms and methods for L2 DA, categorizing them into (quasi) experimental studies, qualitative studies, quantitative studies, and mixed studies. Finally, it provided an overview of the current state of domestic research on L2 DA, including discursive and review articles, curriculum construction, and empirical studies.

5. Conclusion

This chapter summarizes the visual analysis of dynamic assessment (DA) research based on CiteSpace from 1990-2022. It found that Vygotsky is the most influential scholar in the field of DA, and Budoff's DA model: The sandwich format is widely used. DA research has shifted from psychological cognition to language learning and teaching, particularly L2. Poehner and his works are prominent among L2 DA, and research methods have evolved from purely quantitative or qualitative to a combination of both. Future research can focus on speaking, grammar, pragmatics, and translation skills, use mixed-methods strategies, and integrate DA with other conceptual frameworks. Additionally, research could explore the effects of DA on individual factors of learners, such as motivation, emotion, and self-efficacy, and further integrate teaching and assessment in L2 education.
