Insights into computational thinking from think‐aloud interviews: A systematic review

Abstract

This systematic review examines 35 empirical studies featuring the use of think‐aloud interviews in computational thinking (CT) research. Findings show that think‐aloud interviews (1) are typically conducted in Computer Science classrooms and with K‐12 students; (2) are usually combined with other exploratory CT assessment tools; (3) have the potential to benefit learners with special needs and identify the competency gaps through involving diverse participants; (4) are conducted in the absence of cognitive models and standard procedures; and (5) display insufficient definitional and methodological rigor. Theoretically, this review presents a systematic assessment about the application of think‐aloud interviews in CT studies and identifies the limitations in existing CT‐related think‐aloud studies. Practically, this review serves as a reference for studying the cognitive processes during CT problem‐solving and provides suggestions for CT researchers who intend to incorporate think‐aloud interviews in their studies.
