While there has been much work in the language learning and assessment literature on human and automated scoring of essays and short constructed responses, there is little to no work examining text features for scoring of dialog data, particularly interactional aspects thereof, to assess conversational proficiency over and above constructed response skills. Our work bridges this gap by investigating both human and automated approaches towards scoring human-machine text dialog in the context of a real-world language learning application. We collected conversational data of human learners interacting with a cloud-based standards-compliant dialog system, triple-scored these data along multiple dimensions of conversational proficiency, and then analyzed the performance trends. We further examined two different approaches to automated scoring of such data and show that these approaches are able to perform at or above par with human agreement for a majority of dimensions of the scoring rubric.

This study explores the role of quantity of information on vocabulary acquisition in a virtual world. Previous studies have shown that, although it makes interpretation more lengthy, speakers include more information in their referring expressions than is strictly necessary to identify an object - they overspecify. We aim to study the impact of this kind of overspecification on the acquisition of new lexemes in a foreign language. Our hypothesis is that using overspecified expressions during the practice of recently acquired vocabulary will help learners to better remember the lexemes and to exploit them more efficiently later on. In this paper, we describe an experimental study designed to evaluate this hypothesis, comparing two groups of learners who received overspecified and minimally specified referring expressions while practising newly acquired lexemes in the context of a language learning game in Russian. The game is situated in a virtual environment and the interaction is similar to that of a video game. Our results, based on experimental data from participants' performance as well as a post-experiment questionnaire, support the claim that overspecification improves lexical acquisition rates compared to minimal specification. Some pedagogical suggestions are provided for the design of referring expression generation algorithms in Technology-Enhanced language learning (TELL) and computer assisted language learning (CALL) Systems.

This paper describes a computer-assisted language learning (CALL) in a ubiquitous computing environment. The environment, called TANGO (Tag Added learnNinG Objects) system, detects the objects around the learner using RFID (Radio Frequency Identification) tags, and provides the learner the right information for language learning. This system supports learning in daily life with PDA (personal digital assistant) beyond web based education with desktop computers. In the experiment, the learner played the game of TANGO, and was very interested in this system.

The final goal of my research is to develop novel methods that support English as a foreign language (EFL) learners and to increase their English-speaking skills. In this paper, I describe the outline of a mobile application for self-study English-speaking, and also show a learning design which combines practice with the mobile application and a classroom pair work. I also discuss the role of both a technology and a classroom activity for improving English as a foreign language (EFL) learners' oral performance.

Where is the technology-induced pedagogy? Snapshots from two multimedia EFL classrooms

引用

BRITISH JOURNAL OF EDUCATIONAL TECHNOLOGY 2002年第1期33卷 39-52页

作者： Zhong, YX Shen, HZ Univ Sydney Fac Educ A35 Sydney NSW 2006 Australia

This research examines two multimedia secondary EFL classrooms to identify what changes, pedagogical or otherwise, have taken place in technologically integrated classroom practice. The research analyses data generated from a range of sources: classroom observations, videotapes and teacher's lesson plans. It is argued that substantial pedagogical innovations will not come unless there is a perceived change in the understanding of the process of teaching and learning and philosophy of language. The research concludes that the traditional Chinese notion of teaching and the role of the teacher in the classroom need to be redefined to allow for a learner-centred multimedia language classroom to emerge.

The authors earlier developed the Mobile Applications for Scaffolded autonomous summary speaking Task (MAST) for supporting learners' self-study of English speaking. Although MAST enables learners to conduct summary-speaking tasks without teachers' support and improves their oral fluency, it cannot offer enough feedback to enable learners to test whether the listener can comprehend their oral output, which is also necessary for learners to acquire second language. Therefore, we proposed a learning design that combines self-study using MAST and reflection activities in pair work in an English class. This research's objective was to investigate the effectiveness of the learning design for learners' oral performance and to clarify the role of self-study and reflection activities for development of learners' speaking skills. After analysis, we concluded that the learning design was effective for improving learners' oral performances. We also discussed the relation between the oral performances and learners' cognitive process in our learning design.

In a previous study, we developed the Mobile Application for Summary Speaking Task by self-study (MAST) and proposed a learning design which combines MAST and pair work in an English class. Learners practice summary speaking task with MAST by self-study and explain the summary to their peer in a classroom pair work. In this research, we improved the learning design by scaffolding self-study using a task like a conversation and by visualization of learners' learning achievement using proposed worksheet for the pair work aiming to increase the frequency of English-speaking self-study. We conducted an experiment for four weeks and analysis of the results implied that the improved learning design might be effective for increasing the frequency, which occurs from high self efficacy and appropriate self-reflection.

This paper presents nine educational games and activities for learning the Arabic language. The games are developed for Arabiyyatii project, a three-year endeavor that involves re-conceptualization of the curriculum of standard Arabic as a first language in kindergarten. The applications presented in this paper are developed on tabletop surface computers that support a collaborative and interactive learning environment. These applications focus on speaking drills, word production, and sentence recognition of Modern Standard Arabic. This work incorporates an interdisciplinary research framework exploiting best practices used from related disciplines namely: computer-supported collaborative learning, language learning, teaching and learning pedagogy, instructional design and scaffolding.

The increasing demand for learning English as a second language has led to a growing interest in methods for automatically assessing spoken language proficiency. Most approaches use hand-crafted features, but their efficacy relies on their particular underlying assumptions and they risk discarding potentially salient information about proficiency. Other approaches rely on transcriptions produced by ASR systems which may not provide a faithful rendition of a learner's utterance in specific scenarios (e.g., non-native children's spontaneous speech). Furthermore, transcriptions do not yield any information about relevant aspects such as intonation, rhythm or prosody. In this paper, we investigate the use of wav2vec 2.0 for assessing overall and individual aspects of proficiency on two small datasets, one of which is publicly available. We find that this approach significantly outperforms the BERT-based baseline system trained on ASR and manual transcriptions used for comparison.

Interaction and its underlying processes have long been considered foundational to second language learning. language learners, however, are often presented with few opportunities for meaningful, interactive practice. The rapid advancements in speech and language technologies in recent years have given rise to a number of conversational agents seeking to address this need within the interdisciplinary research area of dialogue-based computer-assisted language learning (CALL). While dialogue-based CALL has been shown to foster language proficiency development, it is crucial that a system is evaluated from multiple dimensions, from the technological sufficiency of the underlying components to learning and intercultural outcomes. In this paper, we present the plans and status of three studies targeting different aspects of a conversational agent, Aisla, developed for use in German secondary schools and aligned with the linguistic and intercultural goals of the English as a foreign language curriculum.
