For instance, the makers of the TOEFL would likely argue that we can look at a TOEFL score and make inferences about the test-taker’s ability to do well in university classes because the tasks on the TOEFL resemble (and, more importantly, involve the same knowledge, skills and processes) as the tasks done by students at post-secondary institutions. Older tests like the TOEFL and IELTS are designed around a particular conception of validity. “There is no evidence that those students on Duolingo were failing or, indeed, fraudulent, but just not performing at the same level as peers on their course, so we have chosen to remove acceptance for the test.” A spokesperson told i that the decision was taken because of concerns about student performance.”Īnd quoting a spokesman from that university: “Aston University in Birmingham is one of the many UK institutions that adopted Duolingo at the height of the pandemic but has now dropped it. “Professor John Heathershaw from the University of Exeter linked the acceptance of ‘things like Duolingo tests’ to lower English language standards and described it as a ‘major issue’ when he appeared before the Foreign Affairs Select Committee last week.” Posted in Blog, Duolingo Leave a commentĪ new article in British newspaper i is critical of the Duolingo English Test. They did that some months ago and schools that pay attention to that sort of thing have already adjusted their cut scores, as I’ve reported over the past eight or nine months. Perhaps early access to the results of this study encouraged Duolingo to adjust its score conversion tables. There are many things that affect academic success. Or it may have nothing to do with the test. The lower academic success of DET test-takers may have something to do with the test itself.Or perhaps students arriving with DET scores may need additional academic support to reach their full potential. Given the above, perhaps higher DET cut scores are needed.Students accepted with DET scores enjoyed lower academic success than those accepted with TOEFL and IELTS scores.The same is true of TOEFL and IELTS scores. At the undergraduate level, DET scores were not related to academic success. Students with higher DET scores had more academic success.
Just published in “ Language Testing” are the results of a study into the predictive validity of the Duolingo Engl i sh Test.
