This study investigated the effect of consistent freewriting practice on written fluency development. Thirty-nine first-year university students completed 70 10-minute freewriting activities over the course of an academic semester. Written fluency, measured as words produced per minute (wpm), increased from a mean of 19.5 wpm to 30.1 wpm over a…

Self-Directed Informal Digital Learning of English (SD-IDLE) plays a crucial role in informal language learning. This study aims to examine the SD-IDLE nature of English learning among Indonesian university students and its impact on language learning and personal development. The research used a sequential explanatory mixed methods design,…

This study sought to identify the challenges and needs of TOEFL iBT candidates in achieving C1 level scores in the speaking and writing sections of the exam. To this end, the researcher employed a mixed-method approach to collect data from a population of 46 students, both male and female, between the ages of 22 and 30. The participants were…

Drawing on the framework of invariant measurement from Rasch measurement theory, the purpose of this study is to psychometrically evaluate the 20 language and teaching skill domains of the International Teaching Assistant (ITA) Test using the many-facet Rasch model and to empirically explore performance differences between females and males in…

The purpose of the current dissertation is to map the relationships between first language (L1), writing quality, and syntactic complexity, accuracy, lexical complexity, and fluency (CALF) in second language (L2) writing. CALF are characteristics of language production that have been of significant interest in L2 writing research for the past few…

Professor Glenn Fulcher's research has influenced language testing and assessment in two ways: in proposing a new understanding of data-driven speaking test design, and in drawing attention to the core identity of language testers.

With the wide introduction of English-medium instruction (EMI) to higher education institutions throughout East Asian countries, many East Asian universities are using English proficiency tests that were not originally designed for this context to make admissions and placement decisions. To support the use of these tests in this new EMI context,…

Eye-tracking is primarily used as a tool to capture attentional processes in second language (L2) research. However, it is feasible to design visual displays that can react to and interact with eye-movements in technology-mediated contexts. We explored whether gaze-contingency can foster L2 development by drawing attention to novel words…
