This study investigated conceptual change in novice English teachers’ understanding of English teaching fostered through an Attentive Teaching-based professional development course. In particular, the practice of an approach called Attentive Teaching applied to English teaching enabled the participants to expand their initial concept of English teaching; this change can be seen in multimodal artifacts the teachers produced, involving a visual representation, a written explanation, and an oral presentation. In the course, the concept of teaching English was explored by applying the Attentive Teaching approach, which aligns with other action-oriented approaches under the CEFR framework. The main findings reveal a change in the novice teachers’ understanding: they initially perceived teaching from the outside; as learners, however, following the course, they positioned themselves as leaders of the teaching process in the classroom. This change was observed through creative multimodal products in which each participant expressed their unique point of view, produced at the beginning and the end of the course. The findings illustrate a conceptual change at both the individual and group levels regarding the participants’ understanding of the concept of English teaching. Thus, the practice of Attentive English Teaching is a promising pedagogical tool for inducing and observing conceptual change in novice teachers. Full article

Morocco has recently been cited by the Institute of International Education as a leading destination for Arabic study abroad. However, research has shown that ideologies of language purism and unintelligibility position Eastern varieties of Arabic as more prestigious than Western. Yet, how these beliefs affect learners studying abroad remains an understudied topic, with few studies specifically investigating learners going to Morocco. This study utilizes language learning questionnaires and one-on-one interviews to explore learner beliefs about varieties of Arabic, with particular focus on Moroccan Arabic. Specifically, it looks at four advanced L2 Arabic learners who just started their one-year-long study abroad sojourn in Morocco. Findings show that due to negative stereotypes and misconceptions from native speakers, instructors, and colleagues, learners reported not wanting to learn Darija, the Moroccan variety of Arabic, before studying abroad. However, due to the immediate need of studying and living in Morocco, participants gained interest in Darija and started challenging stereotypes and misconceptions related to this variety of Arabic. These findings highlight the impact of standard language ideology and prestige on learners’ beliefs about what language varieties to study, and how these beliefs may change once learners prepare to and go abroad. Findings from this study support pedagogical and research suggestions to prepare learners for the sociolinguistic realities of the Arabic-speaking world, including critical awareness of ideologies and developing agency in dialect choice.

Background: Although tone acquisition is one of the most challenging aspects for adult second language (L2) learners, research remains limited on how learners from non-tonal first language (L1) backgrounds develop across proficiency levels. The current study examined Mandarin disyllabic tone sequences produced by learners at three proficiency levels. Methods: This study recorded the Mandarin tone production of beginner, intermediate, and advanced Korean learners and evaluated their accuracy and error patterns to determine whether similarities between L1 and L2 prosodic systems affect tone sequence difficulty. Results: Across groups, tone sequence rankings were consistent, differing mainly in accuracy rates. Learners showed an advantage in producing sequences aligned with Korean tonal patterns, such as T1–T1 and T3–T1, which were the easiest to produce. In contrast, sequences without Korean counterparts, particularly those ending in T2, remained the most difficult at all proficiency levels. Conclusions: Neurolinguistic evidence suggests that tones lacking L1 motor representations are disadvantaged by limited motor templates and weaker auditory coding, which together account for persistent difficulty with T2 sequences. Interestingly, T2 in word-initial position improved with experience, as increased exposure and practice helped learners form new sensorimotor routines supported by strengthened auditory–motor coupling. Over time, such experience-dependent neural reorganization enables more precise execution of rising F0 movements when tones occur at the beginning of a sequence, whereas carry-over interference from preceding tones continues to hinder accuracy in word-final position. This study provides insight into how sensorimotor and auditory systems interact in L2 tone learning, offering a neurocognitive framework for understanding prosodic transfer. Full article

Strategic foresight often involves navigating deeply uncertain futures through scenario-based reasoning. Traditional methods rely on static narratives or probabilistic models, which fail to capture the dynamic, interacting, and nonexclusive nature of competing futures. This paper introduces a quantum-inspired framework for scenario interaction grounded in the mathematical formalism of superposition, interference, and contextuality. Agents are modeled as epistemic learners who iteratively update their preferences across multiple narrative pathways, which are treated as basis states in a conceptual Hilbert space. The simulation combines reinforcement learning with stochastic imitation, producing emergent distributions that resemble quantum-like collapse under feedback. Central to the model is the emergence of symmetries in the scenario structure and learning dynamics. Agents begin with neutral priors, facing a balanced reward landscape, epistemic and normative symmetry that is gradually broken through adaptive behavior. However, statistical symmetries persist at the ensemble level, as agents maintain partial preferences and oscillate among futures. These layered symmetries reflect both the cognitive realism of foresight practices and the mathematical tractability of quantum-inspired systems. The proposed model bridges strategic foresight, game-theoretic interaction, and quantum cognition, and offers a novel computational lens to study how futures are constructed, selected, and stabilized under uncertainty.

This study aimed to investigate the effects of mindfulness exercises on the disruptive behaviors of young learners in EFL classes, along with gathering students’ perceptions of their experiences and the perceived change in disruptive behaviors of themselves and their peers. Thirty-nine third-grade students participated in the study and were assigned to the experimental group (EG) and the control group (CG). The EG engaged in mindfulness exercises at the beginning of English lessons for eight weeks, while the CG followed the regular EFL curriculum. Disruptive behaviors were assessed using a Video-based Observation Chart. Interviews were conducted with students to explore their perceptions of the intervention and its impact on their behavior and the behavior of their peers. The results indicated a significant decrease in overall disruptive behaviors in the EG compared to the CG. Participants reported positive experiences and enjoyment as well as perceived increase in attention skills, improvement in emotion regulation and emotional well-being. A minority of the participants stated that they did not observe any difference in the behaviors of some of their disruptive peers. The results indicated that incorporating mindfulness exercises into EFL classes can lead to a reduction in disruptive behaviors, improve students’ experiences, and create a more positive classroom climate.

This study examined how beginners benefit from ‘salience’ in learning two types of visually similar Chinese characters: those with identical strokes (e.g., 人 and 入) and those differing by an additional stroke (e.g., 日 and 白), while identifying the role of color coding and presentation style. A total of 183 non-tonal native speakers with no prior experience of Chinese characters participated in the study. In a 2 × 2 × 2 experimental design, the study assessed the influence of color coding (with vs. without), presentation style (single vs. paired characters), and stroke similarity (identical vs. different) on learning. Results showed (1) Characters with stroke differences were learned more easily than identical-stroke characters; (2) Simultaneous character presentation enhanced discrimination of subtle stroke differences, but (3) Color coding slowed down reaction times, suggesting visual overload. These findings demonstrate that perceptual similarity—not just complexity—impacts character learning difficulty. Pedagogically, the results support using paired character presentation while cautioning against excessive visual enhancements. The study provides empirical evidence for optimizing Chinese character instruction by balancing discriminability and cognitive load in beginning learners. Full article

This paper presents a hybrid fault-diagnosis framework for milling cutting tools designed to address three persistent challenges in industrial monitoring: noisy vibration signals, limited fault labels, and variability across operating conditions. The framework begins by removing baseline drift from raw signals to improve the signal-to-noise ratio. Logarithmic continuous wavelet scalograms are then constructed to provide precise time-frequency localization and reveal fault-related harmonics. To enhance feature clarity, a Canny edge operator is applied, suppressing minor artifacts and reducing intra-class variation so that key diagnostic structures are emphasized. Feature representation is obtained through a dual-branch encoder, where one pathway captures localized patterns while the other preserves long-range dependencies, resulting in compact and discriminative fault descriptors. These descriptors are integrated by an ensemble decision mechanism that assigns validation-guided weights to individual learners, ensuring reliable fault identification, improved robustness under noise, and stable performance across diverse operating conditions. Experimental validation on real-world cutting tool data demonstrates an accuracy of 99.78%, strong resilience to environmental noise, and consistent diagnostic performance under variable conditions. The framework remains lightweight, scalable, and readily deployable, providing a practical solution for high-precision tool fault diagnosis in data-constrained industrial environments. Full article

Providing culturally responsive, trauma-informed afterschool programming is a promising intervention to promote the adjustment, educational achievement, and well-being of newly arrived refugee and immigrant children. Connecting Communities and Multilingual Learners (CCML) is a local nonprofit organization in the Southeastern part of the United States that provides this type of programming to newly arrived families. To better understand their impact on children, CCML aimed to examine its model of programming via a mixed methods, strengths-focused evaluation. Evaluation efforts focused on describing the effects of the program on children at CCML’s flagship site in a robust urban center. Data were collected from students and facilitators at two times (beginning and end of the year) over one academic school year. Results revealed that CCML supported students’ socio-emotional well-being, English language acquisition, and cultural pride in positive and sustaining ways. Evidence from this study suggests that culturally responsive and trauma-informed programs offer promising, adaptable models for addressing the evolving needs of newly arrived refugee and immigrant youth in diverse community contexts.

The present study examines students’ conceptions of comets and meteors using qualitative research methods. A total of 35 semi-structured interviews were conducted with students in grades 7 and 9 in Germany, aiming to gain a richer understanding of how learners conceptualize these phenomena. We identified and categorized distinct mental models related to both the appearance (gestalt) and function of comets and meteors, which are reported in detail in this article. Ideas about meteors tend to align with scientific explanations, whereas answers about comets vary widely and often lack a basic understanding. Based on our data, we recommend that educational approaches begin with a clear introduction to physical properties to establish a solid foundation of knowledge. Both aspects of the gestalt and functionality of comets and meteors should be considered and emphasized in the teaching and learning process. Full article

Studies that have examined /s/ weakening as a social practice have found that L1 Spanish speakers perceive this cue as an indicator of lower status, region of origin, and greater friendliness, and even L2 Spanish learners have been found to associate /s/ weakening with lower status. The question remains, however, whether L2 learners who use /s/ weakening are perceived as having these same social attributes or whether their nonnative status interrupts said assessment. The present study examines the attitudes of 30 beginning and intermediate-level L2 learners of Spanish towards L1 and L2 speech that was digitally modified to contain /s/ deletion in coda positions, a regionally and stylistically variable sociophonetic cue in Spanish that is often not adopted by L2 learners. Participants rated the speech samples on Likert scales of perceived status, solidarity, and nativeness. Results revealed that learners rated L1 speech with /s/ deletion significantly lower for status and L2 speech with /s/ deletion significantly higher for nativeness. Full article

The present study aimed to enhance the understanding of the spelling processes used by young German-speaking learners of English as a foreign language (EFL). Specifically, we sought to (1) compare the children’s accuracy in spelling English real words versus pseudowords to elucidate the role of lexical and sublexical knowledge, and (2) determine which cognitive (phonological awareness, phonological short-term memory, working memory, nonverbal intelligence) and linguistic skills (English receptive grammar and vocabulary) underlie learners’ spelling abilities and misspellings (phonological and orthographic). We followed participants (N = 101) for two years, from the beginning of grade 3 to the end of grade 4. Cognitive skills and linguistic abilities were determined using standardized assessment procedures. Our results indicate that the learners in our study demonstrated greater accuracy in spelling English real words compared to pseudowords. English grammar knowledge significantly predicted real word and pseudoword spelling accuracy, as well as the number of phonological errors, which was the predominant error category. English vocabulary knowledge was a predictor for real word spelling, while nonverbal intelligence predicted pseudoword spelling accuracy. Phonological short-term memory positively predicted the number of orthographic errors (phonologically plausible misspellings but lacking orthographic conventions). Full article

This study aims to develop a reliable method for predicting power plant construction costs during the early planning stages using ensemble machine learning techniques. Accurate cost predictions are essential for project feasibility, and this research highlights the strength of ensemble methods in improving prediction accuracy by combining the advantages of multiple models, offering a significant improvement over traditional approaches. This investigation employed the Random Forest (RF) algorithm to estimate the overall construction cost of a power plant. The RF algorithm was contrasted with single-learner machine learning models: Support Vector Regression (SVR) and k-Nearest Neighbors (KNN). Performance measures, comprising the coefficient of determination ($R^2$), Mean Absolute Error (MAE), and Root Mean Squared Error (RMSE), were used to evaluate and contrast the performance of the implemented models. Statistical measures demonstrated that the RF approach surpassed alternative models, demonstrating the highest coefficient of determination for testing ($R^2=0.956$) and the lowest Root Mean Square Error (RMSE = 29.27) for the testing dataset. The Shapley Additive Explanation (SHAP) technique was implemented to explain the significance and impact of predictor factors affecting power plant construction costs. The outcomes of this investigation provide crucial information for project decision-makers, allowing them to reduce discrepancies in projected costs and make informed decisions at the beginning of the construction phase.

In recent years, several studies across a variety of target languages (e.g., Chinese, French, and Spanish) have demonstrated that students who study abroad acquire target-like patterns of variation. In Spanish-speaking contexts, recent research has moved beyond investigating the acquisition of features specific to Spain to examine that of features used in immersion contexts such as Mexico, the Dominican Republic, Ecuador, Peru, and Argentina. Nevertheless, many of these studies either rely on quantitative variationist analysis or implement qualitative analysis of one or two target dialectal features. In addition, learner omission and expression of pronominal subjects in these contexts have been largely underexplored. Using a mixed-methods approach, this study not only quantitatively examines learners’ production of several features of Buenos Aires Spanish, including sheísmo/zheísmo, /s/-weakening, voseo, and subject pronoun expression, but it also qualitatively relates the production of these features to learners’ experiences during a five-month semester in Argentina. It aims to answer the following research questions: When and to what degree do three English-speaking students studying abroad for five months in Buenos Aires, Argentina acquire target-like production of [ʃ] and/or [ʒ], s-weakening, vos, and subject pronoun expression? How do participants’ experiences, communities of practice, investments, identities, and imagined communities relate to this production? Speech data were gathered prior to, at the midpoint, and at the end of the semester by means of sociolinguistic interviews and elicitation tasks. To further understand the connection between these learners’ use of the target features and their overseas experiences, we explored the case studies of three learners of Spanish of differing proficiency levels (beginning, intermediate, and advanced) using qualitative data collected during semi-structured interviews at each interview time. The results suggest that all three learners increased their production of the prestigious, salient dialectal features of sheísmo/zheísmo and vos during the sojourn and that the amount of increase was greater at each proficiency level. While the beginning and intermediate learners did not move toward target-like norms in their use of the often-stigmatized, less salient, variable features of /s/-weakening and subject pronoun expression, the advanced learner did. As such, stigma, salience, and variability, as well as proficiency level, may play a role in the acquisition of variable features. Learners’ investment in the target language and participation in local communities of practice increased at each proficiency level as well, and learners’ imagined communities beyond their study abroad experiences were related to their identity construction and linguistic choices abroad.

This paper describes large, fine-grained, intentionally inclusive, research-based cognitive models called learning maps. Learning maps are the product of an intensive research synthesis process to develop formal learning models that better reflect the diversity of how learners can learn and be assessed on academic content. Students begin at different places and learn at different rates, and they may have cognitive disabilities or may face a variety of barriers that pose challenges when learning content. Learning maps provide numerous starting points and pathways by which students can acquire and demonstrate knowledge, skills, and understandings. Our work in developing learning maps relies on principles of Universal Design for Learning (UDL), which provides a foundation of flexibility and inclusivity to accommodate students with a wide range of cognitive, linguistic, physical, and sensory profiles. In this paper, we describe learning map design, development, and both qualitative and quantitative methods for the evaluation of map structure. In addition, we offer reflections on our experiences with implementing learning maps as the cognitive architecture for assessments and educational interventions through our work on a variety of projects. With examples from these projects, we describe evidence that shows how learning maps can be useful tools for improving instruction and assessment for all learners. We identify areas where further research and inquiry could prove fruitful and conclude with a discussion of potential areas of extension and offer suggestions for the ongoing refinement of learning maps.

Arabic phonotactics significantly differ from English phonotactics in that they usually follow a framework that forbids the presence of consonant clusters in syllabic onsets. This study examines the relationship between Arabic-speaking EFL learners’ spelling accuracy and pronunciation, concentrating on the difficulties caused by consonant clusters in initial and final positions. A mixed-methods approach was employed, involving audio recordings to assess pronunciation accuracy and a spelling test to evaluate spelling performance. According to the results, words with initial consonant clusters (clusters at the beginning of a syllable, or onset) are harder to pronounce and spell than words with final consonant clusters (clusters that follow the vowel). Initial consonant clusters are considered to demand a quick transition in consonants at the start of a syllable, requiring more exact articulation. On the other hand, final clusters allow for a more progressive and straightforward articulation by involving a consonant transition following the initial vowel sound. Additionally, epenthesis may be used as a method to break up consonant clusters in L1 phonological interference, which is consistent with Arabic phonotactic patterns. Full article
