Comparing Two Related Samples
Comparing two related samples, where data of an outcome variable are paired, is a common task for applied linguistics researchers, such as when seeking to compare pretest and posttest scores among a single group in a (quasi‐)experimental research design or when pairs of individuals have been matched on some variable of interest before (random) group assignment. Of interest in such cases is the difference between values for each pair of observatio…
Mobile language app learners’ self-efficacy increases after using generative AI
Introduction Although generative artificial intelligence (AI) is ubiquitous, there is little research on how it supports self-efficacy (learners’ belief that they can perform at a particular level on a specific task). The purpose of these studies was to investigate self-efficacy development in a generative AI-based language learning experience. Methods In two studies, learners ( N = 385) of French/Spanish used AI-based features offering conversat…
Evaluating the reading and listening outcomes of beginning‐level Duolingo courses
Duolingo is a commercial language‐teaching platform that offers free courses on the web and on mobile apps. This study reports the ACTFL listening and reading proficiency levels of adult Duolingo learners who had completed beginning‐level courses in Spanish or French. The participants ( n = 225) were learners residing in the United States, had little to no prior proficiency in the target language, and used Duolingo as their only learning tool. Th…
Using clustering coefficient to construct weighted networks for supervised link prediction
The Percentage of Words Known in a Text and Reading Comprehension
This study focused on the relationship between percentage of vocabulary known in a text and level of comprehension of the same text. Earlier studies have estimated the percentage of vocabulary necessary for second language learners to understand written texts as being between 95% ( Laufer, 1989 ) and 98% ( Hu & Nation, 2000 ). In this study, 661 participants from 8 countries completed a vocabulary measure based on words drawn from 2 texts, read t…
Cross-cultural pragmatic differences in US and Chinese press conferences
This study investigated request and refusal strategies in the question-response sequences of interactions in routine press conferences held by the Ministry of Foreign Affairs of China and the US Department of State on the topic of the North Korea nuclear crisis during a period of 5 months. All utterances by journalists were identified as requests, and instances of spokes-persons’ non-compliance with requests were considered to be refusals. Findin…
