Sudina Publishes Two Articles and a Book Chapter

Dr. Ekaterina Sudina has recently published two research articles and a book chapter.

The first article, “A Primer on Measurement Invariance in L2 Anxiety Research,” appeared in the 2023 Annual Review of Applied Linguistics issue. The paper outlined the main stages of measurement invariance. It demonstrated the importance of this advanced statistical technique for second-language anxiety questionnaires and other latent constructs in applied linguistics.

The second article, “The Effects of Frequency, Duration, and Intensity on L2 Learning Through Duolingo: A Natural Experiment,” was co-authored with Prof. Luke Plonsky (Northern Arizona University) and appeared in the Journal of Second Language Studies. The researchers examined Duolingo learners’ self-determined exposure and in-app behavior to language gains over time. They provided specific recommendations for foreign language learners concerning app usage frequency, duration, and intensity.

Finally, the book chapter, co-authored by Luke Plonsky (Northern Arizona University), Yuhang Hu (Northern Arizona University), Ekaterina Sudina (ECU), and Frederick Oswald (Rice University) and titled “Advancing Meta-Analytic Methods in L2 Research,” appeared in the Current Approaches in Second Language Acquisition Research: A Practical Guide by A. Mackey and S. Gass (Eds.). This methodological piece introduced several meta-analytic techniques that appear to be either unfamiliar or under-utilized in applied linguistics research but have the potential to lead to greater insights into the nature of second language learning, usage, and assessment.
