HCT cholangiography is a reliable technique that is similar to direct cholangiography in visualizing biliary anatomy, anatomic variants, and choledocholithiasis.

Translanguaging refers to the flexible use of the bilingual repertoire. In this report, we provide a theoretical framework to support the use of translanguaging to assess the academic content knowledge of newly arrived emergent bilingual students. In this report, we argue that translanguaging offers newly arrived emergent bilingual students the opportunity to demonstrate what they know and can do even if their English language and literacy skills are not fully developed. We propose two principles for incorporating translanguaging into initial content assessments for late‐arriving emergent bilingual students, and we theorize how translanguaging can be used within an assessment context by discussing test design applications and considerations. We also discuss some challenges when incorporating translanguaging within an assessment context.

Substantial progress has been made toward applying technology enhanced conversation‐based assessments (CBAs) to measure the English‐language proficiency of English learners (ELs). CBAs are conversation‐based systems that use conversations among computer‐animated agents and a test taker. We expanded the design and capability of prior conversation‐based instructional and assessment systems and developed a CBA designed to measure the English language skills and the mathematics knowledge of middle school ELs. The prototype CBA simulates an authentic and engaging mathematics classroom where the test taker interacts with two virtual agents to solve math problems. We embedded feedback and supports that are triggered by how the CBA interprets students' written responses. In this study, we administered the CBA to middle school ELs (N = 82) residing in the United States. We examined the extent to which the CBA system was able to consistently interpret the students' responses (722 responses for the 82 students). The study findings helped us to understand the factors that affect the accuracy of the CBA system's interpretations and shed light on how to improve CBA systems that incorporate scaffolding.
