Eighty Japanese learners of English as a foreign language encountered 40 target words in one of four experimental conditions (three encounters, six encounters, three encounters with talker variability, and six encounters with talker variability). A picture-naming test was conducted three times (pretest, immediate posttest, and delayed posttest)…

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…

In this study, 118 native speakers of Japanese watched 48 separate video clips in which a teacher provided recasts on phonological or lexical errors to students in Portuguese, a language with which the participants were unfamiliar. In the video clips, six recast characteristics were manipulated: length, segmentation (segmented/whole), prosodic…

Despite an emphasis on oral communication in most foreign language classrooms, the resource-intensive nature (i.e. time and manpower) of speaking tests hinder regular oral assessments. A possible solution is the development of a (semi-) automated scoring system. When it is used in conjunction with human raters, the consistency of computers can…

This study explored the effect of differing levels of interactivity in a VR language learning system on learner oral task performance. 30 participants were divided into 15 pairs which undertook two spot-the-difference tasks. One in a static-VR system, the other in an interactive-VR system which required them to move objects into the correct…

The benefit of Content and Language Integrated Learning (CLIL) for second language (L2) development has been addressed by second language acquisition theory and investigated by empirical studies. However, previous studies have not demonstrated the effectiveness of CLIL precisely as most of their study participants took CLIL and non-CLIL courses…

This paper examines the differences correlation between instructor- and peer-based participation scores and oral proficiency in an EFL course focusing on oral communication. It finds that there is very little correlation between instructor-based and peer-based participation scores (r = 0.187, p = 0.053) and that the former is more associated with…

This paper is an investigation into the use of the group oral discussion test (GOT) to detect changes in speaking proficiency over a two-year period. In this test, three or four test-takers discuss a topic for up to 10 minutes without outside intervention. The performance of 53 Japanese university English major students on this test was videoed…

This paper reports how robot-assisted language learning (RALL) impacts Japanese adults' English speaking skills. With existing research on RALL focusing on children, there is little evidence indicating RALL's effects on adults. We developed a RALL system comprising a robot, a tablet, and designed learning materials for speaking practice. To…

The purpose of the present study is to assess second language (L2) spoken English using automated scoring techniques. Automated scoring aims to classify a large set of learners' oral performance data into a small number of discrete oral proficiency levels. In automated scoring, objectively measurable features such as the frequencies of lexical and…

Task repetition facilitates learners' performance, at least temporarily: Since learners are already familiar with the content of the task at the initial enactment, they are capable of focusing their attention on linguistic form during the following enactment. However, the analysis in previous studies treated various aspects of "form" as…

Languaging has been identified as a contributor to language learning. Yet, compared to oral languaging, such as collaborative dialogs in contextualized settings, little seems to be known about written languaging. In order to fill this gap, this study investigates languaging in the form of "metanotes," that is, metatalk in a written…

The ultimate aim of our research project was to use the Google Web Speech API to automate scoring of elicited imitation (EI) tests. However, in order to achieve this goal, we had to take a number of preparatory steps. We needed to assess how accurate this speech recognition tool is in recognizing native speakers' production of the test items; we…

This paper reports an investigation into how the prompt may influence the discourse of group oral tests. The group oral test, in which three or four participants are rated on their ability to discuss a prompt, is a format for assessing the spoken ability of language learners. In this study, 141 Japanese university students were videoed in 41 group…

Detailed research concerning the issue fluency, specifically relating to pauses, mean length runs, and fluency rates in Japanese EFL learners, is limited. Furthermore, the issue of tracking fluency gains has often been ignored, misunderstood or minimized in EFL educational research. The present study, which is based on six monologues conducted…
