This study aims to identify the most significant characteristics of non-university teaching staff within the general system in Spain who participate in non-traditional tasks outside the school and the classroom within the educational field. An exploratory study was conducted on a sample of 6512 teachers in Spain, using a 13-item Likert-scale questionnaire structured into three scopes (Technical–Political, Scientific–Academic, and Teacher Training). The results identify three distinct profiles of teachers who participate in tasks away from the classroom and the educational institution, according to the educational level at which they work. In the case of Early Childhood Education teachers who participate most in such tasks, the most significant variables are gender, holding a management position, type of school, and Continuous Teacher Training (CTT). For Primary Education teachers, the most important variables are teaching experience, holding a management position, and CTT. Finally, for Secondary Education teachers who participate most in these tasks, the most significant variables across all three scopes are teaching experience, holding a management position, and CTT. Although the proportion of teachers who report dedicating time to tasks outside the classroom and the school is small, a deeper understanding of the characteristics of those who do such activities for the consideration and design of strategies, plans, and policies, targeted by educational level, in order to increase or improve the degree of teacher participation in the three scopes under investigation.

(1) Background: While Hong Kong is renowned for being a multicultural city, its South and Southeast Asian population has experienced disadvantages in various aspects of life, particularly career development. This study adopts the Systems Theory Framework (STF) to investigate the school-to-work transition of Pakistani, Nepalese, Filipino, and Indian youths in the Hong Kong Chinese context. (2) Methods: A qualitative approach using individual and focus group interviews was employed to uncover and critically examine educational and career aspirations and contextual factors in the transition pathways of educational and career advancement experienced by these ethnic groups. (3) Results: Findings show that career aspirations among South and Southeast Asian youths undergoing the school-to-work transition are comparatively lower than those of their counterparts who remain in secondary education. This disparity is attributed to a range of contextual factors, particularly shortcomings in education policy and limited cultural competence within Hong Kong Chinese society, both of which contribute to the erosion of occupational outlook among these underrepresented groups. (4) Conclusions: This study demonstrates the critical impact of contextual factors on the ethnic inequality of school-to-work transition, which are more overwhelming than can be overcome by personal and family efforts. If these issues are not addressed, achieving racial equality and equal opportunity in school-to-work transition will remain a persistent challenge. Full article

This article explores the crucial role of media education and media literacy as effective tools in combating disinformation. In the context of the growing influence of digital media and the increasing spread of fake news, propaganda, and manipulative content, the authors examine the level of awareness among young people regarding key media-related concepts such as media literacy, fake news, propaganda, and disinformation. A sociological survey was conducted among students from two Ukrainian higher education institutions—Ivan Franko National University of Lviv and Lviv Polytechnic National University—involving 277 respondents. The research aimed to evaluate the depth of understanding and preparedness of youth to critically assess media content and recognize signs of manipulative information. The findings indicate a clear trend: media awareness and critical thinking skills improve progressively from secondary school students to university students. This article emphasizes the importance of integrating media literacy into formal education systems as a long-term strategy to build a more informed and resilient society. The authors highlight the need for systematic educational initiatives and practical training in media literacy to empower young audiences in navigating the complex media environment and resisting the impact of disinformation.

The quality of teacher education represents a fundamental pillar for effective educational systems. European and Czech educational policies emphasise alignment with labour market demands and continuous professional development of teachers. This study examines the motivations of and barriers faced by secondary school teachers enrolled in a pedagogical study programme at the Czech University of Life Sciences Prague, contextualised within broader European and national strategic frameworks. Employing a mixed-methods approach, the research combined document analysis of international and national educational policy reports with a longitudinal questionnaire survey of 404 bachelor’s level teacher education students. Chi-square tests and sign residual analyses investigated relationships between labour market position, study motivation, and perceived obstacles. Findings reveal that employer requirements primarily drive educational professionals to pursue further qualifications, whilst other occupational groups cite personal interest as their main motivator. Time constraints emerge as the predominant barrier across all groups, followed by inadequate employer support. No significant association was identified between motivation and perceived barriers. Comparative analysis demonstrates Czech teachers’ lower remuneration satisfaction relative to other countries examined in this research. The study concludes that enhanced employer support and targeted policy measures addressing time constraints are essential for effective teacher professional development. Full article

Ohm’s law has become ubiquitous in numerous scientific and technical disciplines. Generally, the subject is introduced to students in secondary school as fundamental technical knowledge. The present study proposes a visual model to facilitate the comprehension of Ohm’s law in electron transport in solids to pre-university and university students. The objective is to facilitate students’ comprehension of the correlation between electron movement in solids, as depicted by a current, and the energy of the system, which is introduced by the electric field and the material’s structure. The approach’s originality lies in its novel strategy for describing electron trajectory randomization. This enables the establishment of a relationship between the material’s structure and its resistivity. Moreover, the description of electron transport and scattering processes is presented regarding different types of entropy. It shows that electrons follow the maximum trajectory entropy and that thermal entropy has a quadratic relationship with configurational entropy. The determinism of Ohm’s law is inferred from statistical entropy. Full article

Amid ongoing educational reforms and the rapid advancement of the knowledge economy, innovative teaching behaviors are not only closely related to teachers’ professional growth and students’ academic achievement but are also regarded as the key driving force for the evolution of the educational system. Consequently, identifying effective ways to foster teachers’ innovative teaching behaviors has become a central concern in educational psychology and management. Grounded in the Job Demands–Resources framework, this study developed and tested a chained mediation model using survey data from 1165 Chinese elementary and secondary school teachers. The model examines how teachers’ emotional competence fosters innovative teaching behaviors and elucidates the underlying mechanisms. The results revealed that (1) emotional competence significantly and positively predicted innovative teaching behaviors, and (2) teaching efficacy and work vitality served not only as independent mediators but also as sequential mediators in this relationship. These findings extend the understanding of the antecedents of teachers’ innovative behaviors from an emotional perspective, demonstrating that emotional competence, as a critical psychological resource, can be transformed into innovative teaching behaviors through dual “cognitive–motivational” and “energy–motivational” pathways. This study offers both theoretical insights and practical implications for advancing teaching innovation by strengthening teachers’ emotional competence, teaching efficacy, and work vitality.

This study examines refugee integration in South Korea’s emerging asylum context by analyzing how education policies and practices shape inclusion, drawing on interviews with 23 key informants from government and civil society. Despite legal frameworks guaranteeing access, findings reveal how institutional, sociocultural, and political factors create significant policy–practice gaps, hindering both structural integration (enrollment, curriculum, language of instruction, certification) and relational integration (sense of belonging) in schools. Barriers include bureaucratic obstacles, language barriers, discrimination, and limited post-secondary pathways. While civil society actors create opportunities, broader systemic changes are needed to promote the meaningful inclusion of students with refugee backgrounds in South Korean society. Full article

This qualitative study examines how school administrators enact “heartfelt leadership”—a socially and emotionally attuned form of leadership—within Türkiye’s bureaucratic school cultures. Using semi-structured interviews with six administrators and six teachers across primary, secondary, and high school, we employed a basic qualitative design with maximum-variation sampling. Thematic content analysis yielded four themes: (1) principals acknowledge the humanity of their teachers; (2) principals prioritize relationships and go beyond formal duties; (3) bureaucracy constrains but does not fully silence heartfelt leadership; and (4) heartfelt leadership fosters motivation, resilience, and retention. Heartfelt leadership was marked by empathy, recognition of significant moments, and proactive care that extends beyond job descriptions, cultivating trust, motivation, and commitment. Yet rigid procedures and centralized decision-making limited leaders’ autonomy and responsiveness. No consistent gender differences emerged among principals, because all participating teachers were female; therefore, cross-gender comparisons among teachers were not possible. Theoretically, the study bridges emotional-intelligence and bureaucratic-organization scholarship, showing how relational leadership can be sustained in centralized systems through micro-level strategies. Empirically, it broadens global leadership discourse by examining emotional leadership in a non-Western, bureaucratic context. Practically, findings suggest embedding social and emotional competencies in leadership preparation and enabling greater discretionary authority for responsive, human-centered school leadership.

Inclusive education aims to ensure not only academic development but also social participation among students with intellectual disabilities. However, research consistently shows that students with intellectual disabilities are prone to social exclusion in secondary school settings. While theoretical frameworks increasingly highlight the importance of contextual and systemic factors—particularly classroom social dynamics—empirical studies on teachers’ practices for fostering participation remain scarce. This qualitative study investigates how secondary school teachers in inclusive classrooms perceive and enact their role in promoting social participation. Semi-structured interviews were conducted with 30 teachers from various German secondary schools. The data were analyzed using qualitative content analysis based on the social dynamics management (SDM) framework, which distinguishes between universal, selected, and indicated intervention levels. The results reveal that teachers use a wide range of strategies across all three levels. In addition to the categories proposed by the SDM framework, two further areas were identified inductively: (1) teachers’ pedagogical beliefs and (2) internal and external cooperation. These findings suggest a need to expand the SDM model and provide guidance for the professional development of teachers aiming to promote inclusive classroom environments. Full article

Twice-exceptional (2e) students, those who are both gifted and experience learning difficulties, are often overlooked in mainstream educational settings. This paper reports on a qualitative case study conducted in a secondary school in Western Australia, exploring the collaborative experiences of one 2e student, their educators, and their mother. Guided by the neurodiversity paradigm and a strengths-based approach, this study engaged the student, their mother, and educators in co-designing practices that addressed the student’s challenges while leveraging their interests and capabilities. Data were collected through semi-structured interviews, questionnaires, written correspondence, work samples, and analysis of school and specialist reports. While the study found that collaboratively developed, personalised practices can enhance student engagement and wellbeing, it also revealed practical challenges, including time constraints, systemic rigidity, and limited staff understanding of 2e students. This study demonstrated the value and potential of teacher-led inquiry in promoting bespoke, strengths-based educational planning for 2e students, while highlighting the challenges of implementing such approaches within traditional school structures.

This article explores how gender biases in STEM education persist despite formal commitments to equality. Based on data from the Erasmus+ project STEMGenderIN, we analyze responses from lower-secondary school teachers (ISCED 2; ages 11–15), of STEM subjects, in Portugal, Italy, Belgium, and Romania using the TPGESE scale, which assesses three dimensions: perceived gender equality in education (PGEE), the awareness of the effects of gender segregation (AEGSE), and the naturalization of gender stereotypes (GSNGI). Findings show a consistent gap between teachers declared support for gender equality and their limited awareness of structural and cultural barriers faced by girls in STEM. While most teachers affirm equality in principle, many attribute girls’ underrepresentation to personal choice or aptitude, overlooking the influence of stereotypes, social expectations, and systemic inequalities. The results point to a paradox: formal recognition of gender equality coexists with low engagement in reflexive practice or institutional change. Differences between countries suggest varying degrees of critical awareness, with some contexts showing greater openness to questioning dominant narratives. This study highlights the urgent need for teacher training that goes beyond rhetoric, promoting deep pedagogical transformation and equipping educators to create more inclusive STEM learning environments. We argue that addressing the perception–practice gap is essential to closing the gender gap in STEM. To situate these findings, we also note how national cultural–political debates—such as Portugal’s public controversy around so-called “gender ideology” in Citizenship and Development—may shape teachers’ perceptions and self-reports, reinforcing the need for context-aware training.

In most Western societies, intelligence testing has evolved beyond simple measures of language and numerical abilities. Although these measures are valuable in predicting academic achievement and career success, it is widely recognized that modern intelligence assessments offer a more comprehensive view of intellectual aptitude. Unfortunately, in Caribbean Small Island Developing States, like Barbados, despite ongoing efforts towards educational reform and an increasing body of research and related theories advocating for inclusive approaches to understanding and nurturing students’ intellectual development, the education system remains heavily influenced by traditional conceptualizations of intelligence that present a somewhat narrow view of students’ aptitudes. This perspective appears to consider students’ performance on high-stakes examinations measuring numerical and language abilities as perhaps the most indicative markers of intelligence. Building on the work of renowned educational theorists such as Sternberg, Renzulli, and Gardner, and drawing from literature on traditional and contemporary measures of intelligence, this opinion paper examines the implications of deconstructing and redefining traditional views of intelligence within the Barbadian educational context. The value of conventional measures and the potential challenges and limitations associated with transitioning to contemporary intelligence assessments are acknowledged, and the pedagogical and assessment implications at primary and secondary school levels are discussed.

This study critically examines the state of Indigenous education in Taiwan through an interdisciplinary approach that integrates policy analysis, statistical evaluation, and localized case studies. Despite the implementation of progressive legislation, Indigenous students continue to encounter persistent disparities in both secondary and tertiary education. By drawing on national datasets and school-level examples, this paper uncovers systemic mismatches between mainstream educational practices and the linguistic, cultural, and communal realities of Indigenous populations. To contextualize Taiwan’s challenges, this study includes a comparative analysis with Indigenous education in Canada, highlighting both shared obstacles and divergent strategies. The findings indicate that, despite policy reforms and targeted programs in both nations, entrenched inequalities endure, rooted in colonial legacies, insufficient cultural integration, and a lack of community-driven educational initiatives. The article argues for a transformative shift in Taiwan’s education system: one that emphasizes the indigenization of curricula, the inclusion of Indigenous voices in educational policymaking, and greater investment in culturally responsive support mechanisms, particularly at the high school and university levels. In summary, meaningful improvement in Indigenous education requires moving from an assimilationist paradigm to one rooted in cultural respect and self-determination. Full article

Augmented Reality (AR) has emerged as a promising educational tool, offering new opportunities to enhance learning through immersive and interactive experiences. This study aimed to evaluate the degree of acceptance of AR by secondary school students using the Technology Acceptance Model (TAM) as the theoretical framework. A quasi-experimental post-test design was implemented with a sample of 321 students (ages 14–17) who engaged with ComputAR, a mobile AR application developed specifically for a didactic unit on computer systems. Data were collected through a validated TAM questionnaire encompassing five dimensions: “perceived usefulness”, “perceived ease of use”, “perceived enjoyment”, “attitude towards using”, and “behavioural intention to use”. The results indicate a high level of acceptance of AR-based educational tools. Significant differences were found in “perceived ease of use” depending on gender, with male students reporting higher ease, while no gender differences emerged in “perceived usefulness” or “behavioural intention”. Additionally, ICT previous experience was shown to positively affect “perceived enjoyment”, ease of use, and usefulness. In conclusion, these findings confirm the relevance of AR for fostering student motivation and engagement. Full article

In rural Ghana, limited access to affordable, clean cooking fuels drives the need for decentralised waste-to-energy solutions. Anaerobic co-digestion (AcoD) offers a viable route for transforming organic residues into renewable energy, with the added benefit of improved process stability resulting from substrate synergy. This study aims to evaluate the technical feasibility and stabilisation challenges of AcoD, using locally available fruit waste and beet molasses at a secondary school in Bedabour (Ghana). Biological methane potential (BMP) assays of different co-digestion mixtures were conducted at two inoculum-to-substrate (I/S) ratios (2 and 4), identifying the highest yield (441.54 ± 45.98 NmL CH4/g VS) for a mixture of 75% fruit waste and 25% molasses at an I/S ratio of 4. Later, this mixture was tested in a 6 L semi-continuous AcoD reactor. Due to the high biodegradability of the substrates, volatile fatty acid (VFA) accumulation led to acidification and process instability. Three low-cost mitigation strategies were evaluated: (i) carbonate addition using eggshell-derived sources, (ii) biochar supplementation to enhance buffering capacity, and (iii) the integration of a bioelectrochemical system (BES) into the AcoD recirculation loop. The BES was intended to support VFA removal and enhance methane recovery. Although they temporarily improved the biogas production, none of the strategies ensured long-term pH stability of the AcoD process. The results underscore the synergistic potential of AcoD to enhance methane yields but also reveal critical stability limitations under high-organic-loading conditions in low-buffering rural contexts. Future implementation studies should integrate substrates with higher alkalinity or adjusted organic loading rates to ensure sustained performance. These findings provide field-adapted insights for scaling-up AcoD as a viable renewable energy solution in resource-constrained settings. Full article
