This study examined the relationship of linguistic complexity, captured using a set of lexical richness, syntactic complexity, and discoursal complexity indices, to second language (L2) learners' perception of text difficulty, captured using L2 raters' comparative judgment on text comprehensibility and reading speed. Testing materials were 180…

Task design has been viewed to be essential in the context of language assessment. This study investigated whether increasing task complexity affects learners' writing performance. It employs three writing tasks with different levels of complexity based on Robinson's Componential Framework. A cohort of 278 participants was selected using a simple…

This study employed a multi-methods design to investigate the impact of preparation on Chinese test-takers' perceptions of the integrated TOEFL iBT speaking and writing design. Combining results from over 1700 surveys and 10 interviews, it was found that these Chinese test-takers, who are the most vulnerable group in the multimillion testing…

Dative alternation between prepositional and double object datives has been a popular topic in second language (L2) acquisition, but only few studies deal with discourse constraints such as the "given-before-new" principle, or given-new (GN) ordering, which describes the tendency to place given information before new information. The…

This study addresses how Chinese learners of English as a second language (L2) perceive conversations in English materials as compared to speakers of English as a first language (L1). Data were collected through questionnaires completed by 48 participants (28 L2 English learners in China and 20 L1 English speakers in the UK), eliciting evaluations…

The effects of question or task complexity on second language speaking have traditionally been investigated using complexity, accuracy, and fluency measures. Response processes in speaking tests, however, may manifest in other ways, such as through nonverbal behavior. Eye behavior, in the form of averted gaze or blinking frequency, has been found…

This study investigated the effects of four subtitle modes on the listening comprehension of TED (Technology, Entertainment, Design) talks and academic vocabulary learning of intermediate (non-English major) and advanced (English major) English as foreign language (EFL) learners. A total of 272 Chinese college sophomore students were randomly…

This paper investigated how production task combined with teacher feedback (in the form of recasts) affects child second language development, and the effects of task complexity on their production performance. 92 child learners of English in three intact classes were assigned to three tasks of different complexity (simple, +complex, ++complex).…

Face-to-face and computer-mediated collaboration have been used extensively in educational practice. However, research on teaching writing skills for English as a foreign language under collaborative conditions has reported mixed or even negative findings. Cognitive load theory can be used to explain many of these contradictory findings. An…

This study investigates the comparability of three parallel translation tasks selected from a College English Test Band-6 (CET-6) and explores the major linguistic features contributing to translation difficulty. Data obtained from the participants' subjective rating, eye-tracking, and performance evaluation were triangulated to measure the…

Under the framework of item response theory (IRT) and generalizability (G-) theory, this study examined the effects of item difficulty on rating reliability and construct validity on both the constructed-response (CR) items and essay items on English examinations. The data collected for this study were students' scores and responses on the two…

This study examined the development of text complexity for the past 25 years of reading comprehension passages in the National Matriculation English Test (NMET) in China. Text complexity of 206 reading passages at lexical, syntactic, and discourse levels has been measured longitudinally and compared across the years. The natural language…

The purpose of this study is to examine the appropriateness of using the "TOEFL Primary®" tests to evaluate the language abilities of students learning English as a foreign language (EFL) through an online-delivered curriculum, the VIPKid Major Course (MC). Data include student test scores on the TOEFL Primary Listening and Reading tests…

A longitudinal study was conducted to assess changes in and contributing factors of learner belief for a sample of 70 Chinese foreign language learners. Foreign language proficiency and learner factors such as learner belief and learning strategy were measured four times at approximately fifty-day intervals. The results show that there were…

Testlets are subsets of test items that are based on the same stimulus and are administered together. Tests that contain testlets are in widespread use in language testing, but they also share a fundamental problem: Items within a testlet are locally dependent with possibly adverse consequences for test score interpretation and use. Building on…
