The Charismatic Lecturer’s Voice: Explainable Machine Learning Models
machine learning model charisma lecturer's voice...
This study applies explainable machine learning to identify which vocal attributes in a lecturer’s speech influence students’ views of a lecturer’s charisma, a key contributor to teaching quality. It further explores whether vocal qualities differ between male and female lecturers and how students of different genders respond to these differences, offering insights into voice-related factors that influence the impact of educators. Speech segments from YouTube videos featuring 200 native-English lecturers were evaluated by 900 students using charisma rating scales. A set of attributes related to three primary prosodic dimensions of voice - pitch, rhythm, and loudness - was computed. A random forest classifier was employed to predict the charisma level based on the speech attributes and to list and rank the attributes that contributed most to the prediction. The findings revealed prominent vocal attributes that achieved higher charisma scores in the students' ratings. Same-gender evaluations of charisma were mainly based on pitch, while cross-gender evaluations rely mostly on loudness or rhythm. The automated, interpretable method provides a reliable and efficient way to measure vocal charisma in academic lecturers. It can be adapted to examine additional individual factors that influence the perception of a lecturer’s charismatic presence. It may also be integrated into practice-based tools, designed to support instructors in improving their presentation skills. Our research bridges the fields of applied psychology and computer science to contribute to the development of educational technology.

A Mixed-Method Exploration of University Students’ Views about Reality and Knowledge: Combining Semantic Analysis of Textual Data and Quantitative Survey Research
cluster analysis concept maps leximancer semantic network analysis...
Within the context of investigating belief systems, this work exemplifies a mixed-method approach. Two approaches are utilized to explore the philosophical, ontological, and epistemological assumptions that university students foster regarding the relationships between knowledge and reality. In the first step, written materials that elaborated on the matter at hand were subjected to content analysis with the assistance of Leximancer, a software that recognizes themes and concepts and turns textual data into concept maps that express networks of meaning. The second step involved conducting a cluster analysis on the data obtained from the questionnaire to identify distinct groups of participants who shared consistent epistemological viewpoints. The results obtained from the two approaches are in agreement and shed light on the prevalent epistemic inclination that favors a constructivist viewpoint. Discussion on the ramifications of the findings, as well as the methodological issues that are pertinent to the present illustration, is provided.

The Impact of Teachers’ Transformational Leadership on the Soft Skills of Chinese Secondary Vocational Students: The Mediating Role of Self-Efficacy
secondary vocational students soft skills self-efficacy structural equation modelling transformational leadership...
Vocational education plays a pivotal role in nurturing talent and supporting national development. However, challenges such as outdated talent development concepts, insufficient teacher training, and a lack of attention to soft skills cultivation from both schools and students have hindered the comprehensive development of secondary vocational students. This study aims to explore the direct effect of perceived teachers’ transformational leadership on the soft skills of 324 secondary vocational students in China and to examine the mediating role of students’ self-efficacy in this relationship. Using Structural Equation Modeling (SEM), the results show that teachers’ transformational leadership has a significant positive effect on students’ soft skills (β = 0.33, p < .01). Moreover, self-efficacy partially mediates this relationship (indirect effect β = 0.07, p < .05), accounting for 22.6% of the total effect. These findings suggest that teachers’ inspirational motivation, individualized consideration, and intellectual stimulation directly foster students’ communication, teamwork, and problem-solving skills, while also indirectly strengthening them by enhancing students’ confidence. Practically, the study underscores the need for teacher training in transformational leadership and for policy initiatives that integrate soft skills into vocational curricula.

Comparative Effects of School-Based Yoga and Physical Education on Psychological Well-Being of At-Risk Hispanic Adolescents After COVID-19
hispanic adolescents mindfulness practices psychological effects school-based yoga...
This quasi-experimental study compares the differences in psychological well-being impact factors of school-based yoga interventions and mindfulness practices for at-risk Hispanic adolescent high school students with similar students enrolled in traditional physical education classes in a face-to-face setting. Convenience sampling was applied to freshmen students enrolled in a Physical Education 1-hour course at a designated high school in South Texas. A hypothesis model was utilized: mind-body awareness, self-regulation, and physical postures. To assess psychological wellbeing constructs of mood and affect, measurement instruments employed were two commonly utilized questionnaires, the Brunel Mood Scale (BRUMS) and Positive and Negative Affect Schedule (PANAS-C). Statistical analyses included Friedman’s Test for nonparametric data, comparisons of pre-post change scores between yoga and physical education classes, and longitudinal data trends for each measurement instrument’s subscales from inception to conclusion. Overall, longitudinal trends in participant responses from Week 1 to Week 10 comparisons demonstrate a practical significance of gradual increases in improved student well-being in comparison to traditional physical education classes. Overall positive impacts continue to support overall improvement for students participating in Yoga as a form of physical fitness.

Linking College Satisfaction, Professional Identity, and Work Motivation Among Female Ultra-Orthodox Undergraduates: Evidence From an Israeli Campus Survey
academic studies professional identity work motivation ultra-orthodox students...
Academic studies are an important stage in the development of professional identity and perceptions regarding a person’s future occupation. This study examined the relationships between experiences during college studies and professional identity and motivation to work in the studied field among female undergraduates from the Ultra-Orthodox sector. The study employed a cross-sectional survey design with a sample of 93 participants, who were all studying for B.A. degrees on an Ultra-Orthodox college campus. At the end of the 2023 academic year, participants completed anonymous, self-report questionnaires about their attitudes toward academic studies, professional identity, and motivation to work. The data from the questionnaires were analyzed using t-tests, ANOVA, correlation analyses, and multiple regression. The findings revealed significant, positive relationships between satisfaction with one’s studies and professional identity and between professional identity and motivation to work in one’s field of study. Contrary to what had been hypothesized, no relationship was found between the students’ satisfaction with their studies and their motivation to work in their field of study. In addition, the professional identity of students in the later years of their programs was no stronger than that of first-year students. This indicates that perceptions of one’s college studies are not directly related to occupation or motivation for work. The findings show that the year in one’s study program did not affect work motivation, suggesting that the link between academic experience and occupation is weak. In addition, the fact that professional identity did not act as a mediating factor in the examined model suggests that professional identity may develop before individuals begin their college studies.

Self-Organization and Self-Efficacy as Predictors of Cheating Attitudes in Online Exams: A Self-Regulated Learning Perspective
academic integrity cheating attitudes online exams self-efficacy self-organization...
This study aimed to examine the impact of self-organization and self-efficacy in predicting attitudes toward cheating in online exams among undergraduate students. Drawing on the self-regulated learning framework, a cross-sectional survey design was employed to collect data from 153 students at a Saudi university using three validated scales. The findings revealed that self-organization and self-efficacy were significant negative predictors of attitudes toward cheating, with higher levels of these attributes associated with less favorable attitudes toward cheating. Furthermore, moderation analysis showed that self-efficacy significantly moderated the relationship between self-organization and cheating attitudes, suggesting a complex interplay between the two constructs. The findings highlight the importance of fostering self-regulated learning skills to enhance academic integrity in online assessment contexts.

Reconnecting Definitions and Decisions in Research Methodology: A Continuum Framework Linking Worldview to Technique
methodological decisions methodological analysis paradigms framework...
A survey of literature on methodology reveals that the whole-part relationship is broken between the overarching definition of methodology and compatible sets of methodic practices and underlying assumptions. Two key general structures are missing: (a) a big picture view within which to organize definitions and parts, and (b) a framework within which to guide analysis of any particular feature of methodology without detaching from an understanding of the particular in relation to the whole. As a consequence, a basic question remains unanswered about what social scientists mean by methodology. The current manuscript explored literature relating to methodology, without emphasis on any specific paradigm, with the aim of synthesizing both the definitions (i.e., the whole) and components (i.e., the parts) of methodology. Using hermeneutic synthesis, nine definitions of methodology and four methodological decision sets were inferred. Definitions and decision sets were integrated into a range-based methodological framework. The resulting framework captures the continuum of methodological choices made by inquirers, which has implications for educators, methodologists, and researchers seeking to engage in inter- and intra-paradigm methodological analysis to understand and compare methodological decision points.

Teachers’ Acceptance and Understanding of Evolution: A Mixed-Methods Study of Life Sciences Educators in Tshwane North, South Africa
conceptual understanding evolution education life sciences teachers teacher attitudes south africa...
The introduction of evolution in post-apartheid South Africa in 2008 presented significant challenges for teachers, due to both their own and their students' faith-based biases. This study investigates South African teachers' attitudes and understanding of evolution, utilizing Lemkian sociocultural theory and Vygotskian ZPD scaffolding. A mixed-methods approach was employed, including a Likert-scale questionnaire from 91 life science teachers and qualitative insights from open-ended questions. Results reveal a lack of enthusiasm for teaching evolution, influenced by personal religious beliefs and doubts about its scientific validity. Teachers often call for equal representation of evolution and creationism in classrooms. The preparation of teachers must address the stagnant discussion of evolution, while the life sciences curriculum emphasizes the Nature of Science, scientific literacy, and connections between science and society is compromised.

Design and Evaluation of a PBL-Oriented Web-Based Mathematics Learning Environment for Enhancing Problem-Solving and Self-Regulated Learning
mathematical problem-solving problem-based learning self-regulated learning web-based learning media...
This study aims to address students' low mathematical problem-solving skills and self-regulated learning by developing website-based mathematics learning media using the problem-based learning model. Learning that integrates website-based media allows for more independent learning activities in solving mathematical problems. This study uses the ADDIE model to test the validity, practicality, and effectiveness of the product. Website-based media met the validity criteria based on expert assessments with an average score of 137 from subject matter experts and 78.5 from media experts, and the research instruments were declared valid with an Aiken index ranging from 0.9 to 0.99. Website-based media meet the criteria for practicality based on an average teacher assessment of 90.5, an average student assessment of 50.1, and a learning implementation rate of 93%. Website-based media are proven to be effective through four indicators: (1) students who pass exceed the threshold of 80%. (2) One sample t-test results p-value <.05 and t-value >1.69, so that H_0 is rejected. This proves that website-based mathematics learning media are effective in improving students' mathematical problem-solving skills and self-regulated learning. (3) The results of the paired sample t-test show p-value <.05 and t-value >1.69, so that H_0 is rejected. This proves that there is a significant improvement in students' mathematical problem-solving and self-regulated learning abilities after using website-based mathematical learning media. This study is able to facilitate students' problem-solving and self-regulated learning abilities simultaneously in mathematics education.

Team-Based Learning in Undergraduate STEM Education: A Systematic Review of Implementation Practices and Student Outcomes
collaborative learning student learning outcomes systematic review team-based learning (tbl) undergraduate stem education...
Team-based learning (TBL) is a popular form of collaborative learning designed to increase student engagement and motivate students to learn. A growing body of research, particularly in the health sciences, has demonstrated that TBL has positive impacts on student performance and classroom dynamics. However, much less is known about the student outcomes associated with TBL courses in undergraduate science, technology, engineering, and mathematics (STEM) education, fields in which active learning is especially important for student success and retention. To address this gap, we conducted a systematic review of the student outcomes associated with TBL in undergraduate STEM education. Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) method, we identified 55 empirical and qualitative research articles published between 2005 and 2024 that reported on TBL implementation practices and student outcomes. Importantly, we found that most studies described increased student performance and improved measures of classroom dynamics when TBL was compared to lecture-based teaching approaches. These findings provide further evidence that TBL is an effective instructional method and suggest that TBL can be implemented successfully across a wide range of student populations and undergraduate STEM disciplines.

Learning-Oriented School Cultures and Teacher Outcomes: Self-Efficacy as a Mediator in a Centralized Education System
centralized education system instructional effectiveness job satisfaction schools as learning organizations teacher self-efficacy...
This study investigates how learning-oriented school cultures, conceptualized through the Schools as Learning Organizations (SLO) framework, relate to teacher self-efficacy, job satisfaction, and work effectiveness in primary schools within a centralized education system. While these constructs have received considerable attention in the literature, they have rarely been examined together within a unified organizational learning perspective, particularly in contexts marked by limited school autonomy. Using a cross-sectional survey design, data were collected from 94 teachers in nine public primary schools, alongside aggregated student ratings of instructional effectiveness from 364 pupils. The findings showed that learning-oriented school cultures were positively associated with teacher self-efficacy, job satisfaction, and work effectiveness. Teacher self-efficacy also partially mediated the relationship between SLO conditions and both job satisfaction and work effectiveness. These findings indicate that learning-oriented school cultures may strengthen teacher outcomes directly and indirectly by reinforcing teachers’ sense of efficacy. Thus, the role of school leadership in cultivating collaborative and inquiry-oriented professional environments is particularly important

Teacher Victimization in Schools: A Systematic Review of Quantitative Research on Violence Against Teachers (2015–2026)
quantitative research school violence systematic review teacher victimization violence against teachers...
Teacher-targeted victimization remains an under-integrated dimension of school violence research. This systematic review follows PRISMA 2020 guidelines and synthesizes 56 empirical studies (2015–2026) examining how teacher-targeted victimization is conceptualized and analyzed. The review maps patterns in geographic distribution, methodology, behavioral aggression forms, perpetrator framing, and the integration of institutional variables. Findings reveal the predominance of quantitative cross-sectional designs (75.9%). Physical (n = 28) and verbal aggression (n = 26) are the most frequently examined forms, with over half of the studies conceptualizing aggression as exclusively student-perpetrated. Institutional and governance variables remain limited: 84.8% of studies include no institutional variables beyond exposure or rely solely on general school climate indicators, while governance-level constructs appear in only one study. Drawing on Organizational Justice Theory and Institutional Theory, the review advances a Multilevel Institutional Accountability Model that conceptualizes teacher-directed aggression across behavioral exposure, institutional processing, and governance architecture. The findings highlight the need for greater integration of institutional and governance variables in future research.

Academic Development in Sustainability-Oriented Learning Environments: A Qualitative Case Study of the Ocean i3 Project
academic staff development innovation in higher education challenge-based learning sustainability-oriented environments qualitative case study...
University teaching staff are increasingly engaged in innovative sustainability-related initiatives aimed at improving teaching-learning processes while fostering their own academic development. However, the literature has only tentatively explored the impact of this participation on academic development. This work, therefore, aims to analyse the dimensions of the sustainability-oriented learning environment known as Ocean i3 that influence the academic development of university teaching staff. It is based on a case study approach that enables an in-depth and contextualised analysis of this complex phenomenon in a real-world setting. Interviews and a focus group were used as data-collection instruments while inductive content analysis guided the interpretation and discussion of the findings. The results suggest that the complexity of the educational choreography—including project design, institutional context, the teaching team, and the active involvement of staff and students— plays a key role in the academic development of university teaching staff. The study concludes that these dimensions should be strengthened in innovative sustainability-oriented learning environments in order to promote teachers’ academic development.
