It assesses proficiency according to CEFR-J levels, a finely graded adaptation of the CEFR framework tailored to the English as a Foreign Language context, particularly in Japan. CWLA generates scores by combining vocabulary scores with AI-based analytical scores, allowing for a sophisticated, regression-based alignment with CEFR-J proficiency levels. By leveraging both straightforward lexical metrics and advanced AI scoring, CWLA provides accurate and interpretable assessments accessible via a user-friendly web interface. To evaluate CWLA's effectiveness, we conducted validation using the ICNALE GRA dataset, which showed a strong correlation of 0.88 between CWLA scores and human ratings. Additionally, entropy analysis indicated that CWLA's scoring distribution closely resembles human rater patterns, capturing the variability expected in human assessments. Three CEFR/CEFR-J specialists also performed expert validation, resulting in an agreement rate of 83.33 %, thereby supporting the system's alignment with expert judgment. These results suggest that CWLA is a reliable system for detailed CEFR-J level assessment, offering promising applications in language education and learner assessment across proficiency levels.</div></div>","PeriodicalId":101075,"journal":{"name":"Research Methods in Applied Linguistics","volume":"4 2","pages":"Article 100199"},"PeriodicalIF":0.0,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143644269","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study addresses this gap by analyzing tutoring conversations from diverse contexts, particularly English as a Second Language (ESL) tutoring and algebra instruction, using seven computational models. These models yielded 29 synchrony indices, ranging from traditional lexical overlap to advanced natural language processing-based embedding models, capturing synchrony across multiple dimensions.

In this worldview, a space or place continues to resonate even after one leaves it, and time is seen as circular rather than linear, linking the past, present, and future. This interconnectedness is embodied in the concept of 'va', which emphasizes the importance of understanding relationships and responsibilities within the community involved in research (cf. Airini et al., 2010). This article argues for the importance of recognizing Indigenous epistemologies and ontologies as valid in their own right, which in this case means recognizing the importance of va in Pacific research. We also present our theorization of an Engaged and Fluid Temporal Methodology, which outlines via five principles how Pacific understandings guided our work with Pacific communities. We then walk through each of the five principles as a methodological guide for community-based research, providing illustrative examples from the Wellington Translanguaging Project. By focusing on principles to research that are imbued with respective Pacific understandings of time, space, and relationships (e.g. va), we argue that this supports the research to remain in and for the communities with which we worked, a core component of Indigenous research methodology.</div></div>","PeriodicalId":101075,"journal":{"name":"Research Methods in Applied Linguistics","volume":"4 1","pages":"Article 100198"},"PeriodicalIF":0.0,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143610704","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, EI tests are perhaps underutilized because of the need for time-consuming scoring by hand. A clear solution to this is computer automation, which requires two key components to work in parallel: (1) an accurate automatic speech recognition (ASR) system to transcribe EI response speech into text, and (2) a computational scoring metric to assess the resulting text. In this paper, we test the feasibility of automating EI scoring with the open-source Whisper ASR system and the Word Error Rate (<em>WER</em>) scoring metric which measures deviation from the original prompt. 30 Japanese L1 participants took a 30-item test, resulting in 900 English L2 learner EI sentence responses which were transcribed by the two authors and Whisper ASR. The intraclass correlation coefficient (ICC) between the error rates of the human raters and Whisper across all items was ICC = 0.929, 95 % CI [0.921, 0.936] indicating very strong alignment. We then compared automated test scores using <em>WER</em> to those done manually by human raters using a traditional ordinal-scale scoring method developed by Ortega et al. (2002) and found a robust correlation of <em>r</em> = 0.969, 95 % CI [0.935, 0.985] across overall participant scores. These findings show that the combination of the Whisper ASR system and the <em>WER</em> scoring metric result in EI test scores that align almost perfectly with and are arguably an improvement on currently accepted methods.</div></div>","PeriodicalId":101075,"journal":{"name":"Research Methods in Applied Linguistics","volume":"4 1","pages":"Article 100197"},"PeriodicalIF":0.0,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143592104","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The construct of trajectory connects one's biographical histories, situated practices and experiences and their ensuing consequences vis-à-vis wider social, cultural, political and economic spaces. Trajectory contributes to identity and subjectivity research by allowing for the examination of evolving identities and subjectivities over time, thereby shedding light on the process of becoming. In identity and subjectivity research, stance is often used as a heuristic. However, stance only captures identity and subjectivity at a particular point in time; it does not help to trace identity trajectories that take place across timescales and events. This paper therefore introduces the idea of <em>narrative trajectory</em> as an analytical approach, drawing on sociolinguistic and linguistic anthropological work on stancetaking, chronotope and interdiscursivity. Social actors take stances through narrated events and narrating events, which can form narrated and narrating trajectories respectively if interdiscursive links between events can be traced. The tracing of such links can be accomplished by attending to various types of signs, models or social positions and relevant spatial-temporal configurations (chronotopes) across multiple narrated and narrating trajectories. Taken together, this multiplicity of trajectories forms an overall narrative trajectory. This paper discusses the tracing of a narrative trajectory with an ethnographic case study of an English learner in Hong Kong. The concept was applied to show how her identity as a struggling learner emerged and evolved across time and space. Recommendations for identity and subjectivity research in applied linguistics are also provided.</div></div>","PeriodicalId":101075,"journal":{"name":"Research Methods in Applied Linguistics","volume":"4 1","pages":"Article 100189"},"PeriodicalIF":0.0,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143549577","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These studies have used machine translation evaluation metrics, acoustic fluency measures, and computational linguistic indices as separate approaches to model rater judgments of interpreting quality. Nonetheless, limited research has integrated these three types of measures within a single framework. To address this gap, this exploratory and proof-of-concept study adopts an integrative approach, combining these three types of measures to model rater judgments of interpreting quality as a classification problem. Using a dataset of 161 Chinese-to-English interpretations, we applied ordinal logistic regression analysis to identify significant predictors across fidelity, fluency, and linguistic dimensions. The analyses yielded two sets of significant predictors, including (a) COMET-22, mean length of unfilled pauses, mean length of run, and mean word length, and (b) BLEURT-20, phonation time ratio, speech rate, mean word length, type-token ratio for content words, type-token ratio for all words, and mean word frequency for content words. These models performed well on the testing dataset, particularly for classifying interpretations into four bands of overall interpreting quality (e.g., accuracy = .643, 1-off accuracy = .805), based on the Rasch-calibrated scores from human evaluation. These findings suggest that this integrated approach may enhance the precision and scalability of IQA and has the potential to reduce logistical burdens in large-scale professional interpreter certification exams and language proficiency tests.</div></div>","PeriodicalId":101075,"journal":{"name":"Research Methods in Applied Linguistics","volume":"4 1","pages":"Article 100194"},"PeriodicalIF":0.0,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143549576","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper critiques such studies, suggesting that labeling them as ‘longitudinal’ can obscure their failure to fully capture the ongoing temporal nature of learning. Qualitative longitudinal research offers a solution to this limitation by establishing a framework in which the changing effects of time can be better understood. This paper advocates for strengthening this approach by integrating multiperspective research, which involves gathering insights from multiple viewpoints during study design, data collection, and analysis. To illustrate this research approach, data from a study on English-medium instruction (EMI) in Hong Kong is presented. In this study, 26 undergraduate students were tracked throughout their four-year degree programs, supplemented with insights from 20 EMI lecturers and 20 English-language instructors, who offer a broader, more nuanced view of the students' learning experiences and temporal shifts. Together, these perspectives provide insight into temporal changes within broader time frames and reveal students’ overall undergraduate journey as they acclimate (and at times do not acclimate) to the various challenges associated with learning through the medium of English.</div></div>","PeriodicalId":101075,"journal":{"name":"Research Methods in Applied Linguistics","volume":"4 1","pages":"Article 100192"},"PeriodicalIF":0.0,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143510278","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
