Towards a framework of critical thinking for assessing EAP speaking

As one of the fundamental skills of the 21st century, critical thinking (CT) is a topic of considerable interest within the domain of assessing English for academic purposes (EAP). Recent literature on EAP instruction and assessment indicates that EAP has evolved beyond a strict focus on language improvement to encompass discourse competence and broader academic literacy development, with CT playing an important role in academic communication. A fundamental consideration in educational assessment is the construct that defines the knowledge, skills, or abilities to be assessed. However, CT has not received due attention in the research literature on EAP speaking assessment, thus raising a legitimate concern about its underrepresentation in the academic speaking construct. This study draws on Macqueen's (2022) distinction between theoretical, stated, perceived, and operationalized assessment constructs, with an aim to describe the EAP speaking assessment construct by including the concept of CT. By establishing alignment between what the literature indicates (theoretical), what assessment requires (stated), and how people understand assessment (perceived), a CT assessment framework is proposed to reflect how test takers experience it (operationalized). Our study contributes to a more nuanced conceptualization of CT in the context of EAP speaking, with implications for EAP speaking test development.
