Abstract This study investigated how students’ self‐reported individual differences predicted second language (L2) spoken discussion task output, an objective behavioral outcome, in the Japanese university English as a Foreign Language (EFL) context. Although numerous psychological theories are used as a rationale for task‐based language teaching (TBLT), few studies have investigated the impact of individual differences variables on task performance. To address this gap, a cross‐validation procedure was used with students (N = 439) from two different universities. They completed questionnaires to measure willingness to communicate (WTC), speaking self‐efficacy (SSE), and perceived communicative competence (PCC). They also engaged in a quasiacademic eight‐minute group discussion task (TBLT design). This discussion was recorded and transcribed, with the number of words produced used as an objective measure of L2 task production. In the better fitting mediation structural equation model, the influences of SSE and PCC on spoken L2 task production were fully mediated by WTC (R² = .21).

Phrasal verbs are important for successful communication and yet are incredibly challenging for language learners. The current study compared two exercise formats for the learning of phrasal verbs. One format draws attention to the verb, while the other brings into focus the particle. In the verb-focused format, students were asked to guess the missing verb before receiving feedback. In the particle-focused format, they were told to guess the missing particle before feedback was presented. The results of a cued-recall test showed that the recall of phrasal verbs was enhanced more effectively in the particle-focused format than in the verb-focused format, although this advantage diminished after one week. A multiple-choice test revealed no significant difference between the two methods in terms of their impact on the recognition of phrasal verbs. The current study also aimed to test the prediction of the episodic recollection hypothesis, which specifies that memory of the initial guess plays a critical role in the subsequent recall of the correct answer. It was also found that asking students to recall their initial guess moderated their performance in the posttest. Overall, the findings of the current study suggest that the particle-focused format boosts the memory of phrasal verbs and that to minimize the adverse effects of proactive interference, it is vital for students to remember their errors. This means that teachers would be advised to focus on exercises that provide the verb and encourage guessing of the particle.

Self-efficacy has emerged as a popular construct in second language research, especially in the frontline and practitioner-researcher spaces. A troubling trend in the relevant literature is that self-efficacy is often measured in a general or global manner. Such research ignores the fact that self-efficacy is a smaller context-driven construct that should be measured within a specific task or activity where time, place, and purpose domains are considered in the creation of the measurement. Task-based language teaching researchers have also largely neglected the affective factors that may influence task participation, including self-efficacy, despite its potential application to understanding task performance. In this report, we present an instrument specifically developed to measure English as a foreign language students’ self-efficacy beliefs when performing a dialogic, synchronous, quasi-formal group discussion task. The instrument's underlying psychometric properties were assessed ( N = 130; multisite sample from Japanese universities) and evidence suggested that it could measure a unidimensional construct with high reliability. The aggregate scale constructed from the instrument's items also displayed a central tendency and normal unimodal distribution. This was a positive finding and suggested that the instrument could be useful in producing a self-efficacy measurement for use in the testing designs preferred by second language researchers. The potential applications of this instrument are discussed while highlighting how this report acts as an illustration for investigators to use when researching self-efficacy.

Abstract In recent years, there has been considerable interest in how to maximize learners' retention of multiword expressions. One technique that has been shown to be highly effective is the use of exercises such as those found in mainstream English as a second language textbooks. In the present study, we investigated how the execution of a gap‐fill exercise impacts the learning of phrasal verbs with 118 learners studying English as a foreign language. Participants completed a gap‐fill exercise by referring to the answer key, or they received the answer key only after completing the exercise. The effects of the learning conditions were assessed with tests for measuring productive and receptive knowledge at two retention intervals. The results from mixed‐effects logistic regression modeling showed that both executions of the gap‐fill exercise led to similar rates of retention. The findings largely challenge previous research. We also explored how to minimize proactive interference when participants make errors in gap‐fill exercises by asking them to recollect their initial guesses during the posttests. The results showed that when the initial guess was produced, correct recall of the target phrasal verbs was much greater than when the guess was not recollected. The finding indicates that memory for the initial guess may play a vital role in how participants learn from their errors. The pedagogical implications of the findings are discussed, and future areas of research are proposed.

Abstract Researchers investigating TBLT have used psycholinguistic and sociolinguistic theories in support of the approach, but there has been limited discussion of motivational frameworks. A framework for motivation within TBLT would enhance our understanding of learner motivation, and could be utilised in future studies. This paper argues that Self-Determination Theory is an appropriate framework. After briefly describing the key tenets of TBLT and SDT, the paper shows how SDT helps us understand the motivational benefits of tasks. It outlines the six mini-theories of SDT, and aligns them with existing studies to highlight how results may be explained by these theories. Some suggestions are then provided as to how these theories can be used for conducting future classroom-based research.

Measurement of language learners’ development in speaking proficiency is important for practicing language teachers, not only for assessment purposes, but also for evaluating the effectiveness of materials and approaches used. However, doing so effectively and efficiently presents challenges. Commercial speaking tests are often costly, and beyond the budget of many schools, and the use of frameworks such as Complexity, Accuracy, Lexis, and Fluency place great demand on teachers’ limited time. This article reports on two tests that potentially offer a practical solution to these problems. The speaking proficiency of 75 students in an oral English course at a university in Japan was measured three times over the course of an academic year using short, spoken narratives assessed by human raters with a specially-designed rubric, and a completely automated computer-based test. The many-facet Rasch measurement model was used to analyse the human raters and the rubric, and to provide scores for the subsequent analyses. Mixed-level modeling was used to model growth in speaking proficiency over the academic year, and correlation was used to assess the relationship between the two test types. The results show that both tests were able to measure growth in speaking proficiency, but only in the first half of the year. There was moderate correlation between concurrent administrations of the two tests, suggesting they are measuring the same construct. Results of the narrative test suggest that the rubric was reliable and effective in measuring speaking proficiency in this context, and also provide strong evidence supporting the use of FACETS when human raters are used to evaluate speaking.

Abstract This paper outlines a classroom-based study on the timing of explicit language instruction. It also provides an alternative to the CALF (Complexity Accuracy Lexis Fluency) framework for analyzing learner language, which may not always be appropriate for EFL contexts. Two groups of learners, assigned to either a TBLT or a PPP condition, completed a speaking task. A follow-up task was given three months later, but with no explicit language focus for either group. Data from these interactions were analyzed for use of target grammar structures and overall speaking proficiency. Results suggest that explicit introduction of language through PPP benefits immediate task performance, but that ultimately post-task focus on language through TBLT leads to greater language development. The framework for analysis was effective in showing differences in performance between the groups in this context.

Groupwork has become ubiquitous in language education, with the clear benefits of interaction and output on language acquisition. A body of research has investigated this interaction in pairs and small groups, and there is an increased understanding that individual group context is a key factor in determining the behavior of students. This article reports on a study that first investigated emergent leadership within groups, and the influence of the group on leader stability. The study then examined how leadership is represented in student task engagement. Students were placed into fixed small groups for the first semester, and then allowed to self-select into groups for the second semester. Perceptions of leadership were measured three times in each semester, and leaders were identified in each group. Results showed that changing group membership had a considerable impact on leadership stability, and student interaction was then analysed to determine how leadership influenced engagement with tasks. Students with high leadership displayed high engagement with tasks, and took a central role in driving the conversation. When a student chose to reject the role of leader there was a dramatic impact on their engagement in conversation. The stability of leadership and its impact on performance has practical implications both for researchers and teachers.

A considerable proportion of English language education throughout the world occurs in monolingual compulsory settings. It is therefore not surprising that both teacher and students' use of the L1 is a common feature of these classrooms. This study, conducted in a language classroom, used a sociocultural framework to discover how Japanese high school students use their first language while engaging in oral communicative tasks. Observations were followed by student interviews in order to ascertain students' attitudes toward the use of Japanese in English classes. Students' use of Japanese was generally found to be positively related to learning, and it emerged that there were specific contextual factors which influenced students' use of their first language, and the implications of this are discussed. © 2011 Blackwell Publishing Ltd.
