Complexity, accuracy, and fluency (CAF) as measures of language proficiency have been used extensively in assessing second language production in English language studies related to task-based language teaching. The present review adds the following critical elements to the existing body of literature: (i) Provides synthesis and critical analysis…

Language learning activities involving time-pressured repetition of similar content have been shown to facilitate improvements in fluency. However, concerns have been voiced about whether these gains might be offset by reduced levels of grammatical accuracy. This descriptive study tracked the oral proficiency of 32 Japanese university students…

The current study examined the extent to which first language (L1) utterance fluency measures can predict second language (L2) fluency and how L2 proficiency moderates the relationship between L1 and L2 fluency. A total of 104 Japanese-speaking learners of English completed different argumentative speech tasks in their L1 and L2. Their speaking…

Research is scarce about the lexical processes undertaken by thousands of L2 learners worldwide who already command one or more languages. Some aspects involved in lexical organisation and production, such as clustering and switching, have been traditionally approached through manual methods, which depend on subjective judgments of semantic…

This study examines the developmental relationship between L2 Chinese oral fluency and self-repair in Dutch students learning Chinese. In this study, 76 junior Dutch students were split into two different groups based on level and were tested at two time periods (T1 and T2) for L2 Chinese fluency, which included the control variables of repetition…

The study aims to determine whether exposing EFL Saudi undergraduate students to TED talks could effectively contribute to the improvement of their oral language proficiency. To achieve this goal, 32 English as a Foreign Language Saudi undergraduate students were recruited to participate in the study. These students were selected based on their…

The purpose of the current study was to examine the effect of utilizing a program based on post-constructivism to develop adult learners' English language fluency. The study started with the literature review and previous studies handling post-constructivism and English language fluency. The researcher nominated a group of pre-intermediate to…

Study abroad is an important piece of the internationalization of curriculum and is particularly advantageous for second language learners. Many students study abroad to learn a language and the majority of students studying abroad enroll in shorter-term programs. Given their strong representation in the field of study abroad, the following…

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…

Recent research in second language acquisition suggests that a number of speed, breakdown, repair, and composite measures reliably assess fluency and predict proficiency. However, there is little research evidence to indicate which measures best characterize fluency at each assessed level of proficiency and which can consistently distinguish one…

The present study investigates the efficacy of preparation time in four speaking tasks of TOEFL iBT. As the current pre-task planning time offered by ETS is very short, 15 to 30 seconds, we intended to explore how the test-takers' speaking quality would change if the preparation time was added to the response time, giving the respondents a…

This study explored two assessment approaches to oral performances: analytical complexity, accuracy, and fluency (CAF) indices and human raters' evaluations. CAF indices are frequently used in second-language speaking (L2) research; however, because tasks are communicative and goal-oriented, the degree to which students achieve such communicative…

Background/purpose: This research aimed to evaluate the impact of integrating the WSQ-based flipped learning method with cooperative learning on speaking performance among English as a Foreign Language (EFL) learners. Addressing the challenges EFL learners face in oral proficiency, the study sought to determine whether this innovative pedagogical…

The present study explores lexical collocations and their relation to speaking proficiency of Taiwanese EFL college students learning English for academic purposes (i.e., EAP). The data is obtained from 92 English majors at a national university of science and technology in southern Taiwan. The results show that: (a) direct collocation instruction…

This study investigated phase transitions in EFL students' speech fluency development using a complex dynamic systems perspective. Two students with different proficiency levels were selected from an intact speaking class. These students learned and practiced specific strategies to improve their speech fluency. Phase transitions were analyzed…
