This study employed a quantitative correlational approach involving 165 heads and tutors from 39 PKBM units in East Bogor Regency. Data were collected through a structured questionnaire and analyzed using descriptive statistics, prerequisite tests, path analysis, and SITOREM analysis. The findings showed that servant leadership, organizational climate, Organizational Citizenship Behavior, and the effectiveness of education and training had positive direct effects on PKBM sustainability. Servant leadership and organizational climate also had indirect effects on PKBM sustainability through Organizational Citizenship Behavior and the effectiveness of education and training. The SITOREM analysis identified several indicators requiring priority improvement, including conceptualization, forward looking orientation, satisfaction with activities, meeting community needs, development and empowerment, availability of teaching staff, PKBM development, and work mechanisms. These findings indicate that PKBM sustainability is shaped not only by leadership and organizational conditions, but also by voluntary work behavior and continuous human resource development. The study recommends strengthening servant leadership, improving organizational climate, enhancing tutors’ extra role behavior, and designing more relevant education and training programs to support the long term sustainability of PKBM.</em></p>2026-06-08T11:44:51+07:00Copyright (c) 2026 Journal La Eduscihttps://newinera.com/index.php/JournalLaEdusci/article/view/3198Development of Interactive Digital Modules Based on Local Wisdom of Gandrung Lombok Dance on Plane Figures Material2026-06-08T13:04:48+07:00Erna Anggrainiernaanggraini@uinmataram.ac.idDjuita Hidayatidjuitahidayati@uinmataram.ac.id<p><em>Integrating cultural contexts into mathematics learning has increasingly been recognized as an effective strategy to enhance students’ conceptual understanding and engagement. However, the incorporation of local cultural resources into digital learning media remains limited, particularly in mathematics education.

This study aims to examine the integration of Islamic counseling and education within the unique educational ecosystem of Indonesian pesantren, focusing on three modern institutions: Darul Arafah Raya, Nurul Hikmah An-Nahdly, and Darul Ihsan in North Sumatra. Employing a qualitative multiple case study design, data were collected through in-depth interviews, participant observation, and document analysis to explore how counseling is embedded within educational practices. The findings reveal that Islamic counseling is not implemented as a separate service but is systematically integrated into the educational process, encompassing classroom learning, dormitory life, and religious activities. This integration fosters a holistic model of student development that combines spiritual, emotional, and social dimensions. Core values such as sabr (patience), tawakkal (reliance on God), and muhasabah (self-reflection) function as pedagogical tools for emotional regulation and character formation, continuously reinforced through structured programs and daily interactions. The effectiveness of this model is further supported by institutional synergy among kyai, teachers, counselors, and dormitory supervisors, creating a comprehensive and collaborative educational environment. Unlike conventional Western approaches that tend to separate counseling from instructional processes, this model represents a proactive and value-driven framework that integrates counseling into the core of educational practice. The study concludes that the integration of Islamic counseling and education offers a culturally responsive and sustainable approach to holistic student development, contributing to the broader discourse on decolonizing educational and counseling practices. </em></p>2026-06-19T13:40:07+07:00Copyright (c) 2026 Journal La Eduscihttps://newinera.com/index.php/JournalLaEdusci/article/view/3110Implementation of TPACK-Integrated Problem-Based Learning to Improve Students' Higher-Order Thinking Skills on Newton's Laws2026-06-19T15:39:24+07:00Meltinur Asqorymelti241203@gmail.comFibrika Rahmat BasukiBasuki@gmail.comDedi SastradikaSastradika@gmail.com<p><em>The low Higher Order Thinking Skills of Indonesian students in Physics lessons encouraged the conduct of this quasi experimental research to investigate the influence of the problem based learning model integrated with technological pedagogical content knowledge on newton's law material.

These limitations make it difficult for deaf students to construct sentences according to Subject, Predicate, Object, and Complement/Adverbial (SPOK) patterns. In addition, conventional learning methods often reduce students’ interest and make it difficult for them to understand sentence structure properly. Therefore, digital learning media are needed to support visual-based learning that suits the characteristics of deaf students. This study aimed to develop the KALISAD application to improve structured sentence writing skills among deaf students and to facilitate a more interactive, attractive, and understandable learning process. This research employed a research and development (R&D) design using the ADDIE model, which consists of analysis, design, development, implementation, and evaluation stages. The study used a pretest-posttest approach with quantitative data analysis. The subjects were eight deaf students at the senior high school level of SLB A. Data were collected through observation, interviews, tests, expert validation sheets, and practicality questionnaires. The validation results showed that the KALISAD application was very valid and feasible for use. The instrument validation reached 94.59%, material expert validation 93.18%, media expert validation 94.38%, and deaf education expert validation 96.88%. The practicality score was 88.89%, indicating that the application was practical to use. The effectiveness test using the N-Gain formula showed an average score of 0.42, categorized as moderate.

This study aims to analyze the utilization of AI in education, identify its opportunities and challenges, and explain its implications for future learning. This research employed a qualitative approach with a library research design. Data were obtained from scientific journal articles, books, book chapters, proceedings, and relevant academic sources discussing AI in education. The selected literature was mainly focused on recent publications and was analyzed using qualitative descriptive analysis through data reduction, data presentation, and conclusion drawing. Source triangulation was applied to strengthen the credibility of the findings. The results show that AI is utilized in education through adaptive learning systems, intelligent tutoring systems, educational chatbots, automated assessment, learning analytics, and interactive digital media. AI provides opportunities to support personalized learning, improve learning efficiency, expand access to education, strengthen digital literacy, and develop 21st-century skills. However, its implementation also faces challenges, including limited technological infrastructure, low teacher digital competence, digital inequality, academic ethics issues, data privacy concerns, technology dependence, and reduced social interaction. The study also indicates that AI changes the roles of teachers and students, where teachers are increasingly positioned as facilitators, mentors, learning designers, and ethical guides, while students are encouraged to become more independent, critical, and digitally literate learners. Therefore, AI should be integrated into education as a supporting tool that strengthens, rather than replaces, human-centered learning.

Education plays a strategic role in strengthening climate awareness and encouraging pro-environmental behavior, with teachers serving as key agents in shaping students’ knowledge, attitudes, and daily practices. This study examined the relationship between climate change literacy and pro-environmental behavior intention among teachers at the Al-Ashriyyah Nurul Iman Islamic Boarding School Foundation in Bogor. A quantitative cross-sectional survey design was employed involving 120 active teachers from elementary, junior high, and senior high school levels. Climate change literacy was measured through three dimensions: knowledge of causes, knowledge of impacts, and knowledge of actions/mitigation, while pro-environmental behavior intention was measured through items related to energy saving, water conservation, waste management, paper reduction, and recycling practices. Data were analyzed using descriptive statistics, Pearson correlation, and multiple linear regression. The findings show that teachers demonstrated stronger agreement with direct causes of climate change, locally perceived impacts, and low-cost mitigation actions. Correlation analysis indicated that all dimensions of climate change literacy were positively associated with pro-environmental behavior intention, with knowledge of actions/mitigation showing the strongest relationship, followed by knowledge of impacts and knowledge of causes. Regression analysis further showed that knowledge of actions/mitigation and knowledge of impacts significantly predicted pro-environmental behavior intention, while knowledge of causes was not a significant predictor when the other dimensions were included in the model. These findings suggest that climate change education for teachers should move beyond scientific explanations of causes and emphasize contextual impacts and applicable mitigation practices. </em></p>2026-06-26T13:59:03+07:00Copyright (c) 2026 Journal La Eduscihttps://newinera.com/index.php/JournalLaEdusci/article/view/3325Linguistic Microaggressions in Indigenous Educational Community Environments: A Pragmatic Study of Language Use2026-06-29T10:14:08+07:00Nuzmi Sasferinuzmi0506@gmail.com<p><em>Linguistic microaggression is a subtle form of discriminatory communication that frequently occurs in multicultural educational interactions and may affect social relationships, cultural identity, and language practices within indigenous communities.

An explanatory sequential mixed methods design was employed. Quantitative data were collected from 30 participants representing native-speaking communities, religious education communities, and migrant communities in Kerinci and Sungai Penuh through a structured questionnaire. The data were analyzed using descriptive statistics, the Kruskal–Wallis test, and Spearman rank correlation. Qualitative data were obtained through in-depth interviews, conversational observations, and naturalistic recordings and analyzed using thematic analysis. The quantitative findings revealed significant differences in pragmatic language politeness among the three community groups (χ² = 29.000, p < 0.001). A strong positive relationship was found between intercultural and ethnolinguistic engagement and pragmatic language politeness (ρ = 0.866, p < 0.001), while linguistic microaggression dimensions showed moderate negative correlations with pragmatic language politeness (ρ = −0.500, p < 0.05). Qualitative findings identified recurring patterns of microinsult, microinvalidation, and microassault, alongside mitigation, face-saving, and intercultural adaptation strategies used to maintain social harmony.

In early childhood education settings, post-disaster trauma may directly affect emotional regulation, classroom participation, and learning engagement. This study aimed to examine manifestations of trauma among children aged 3–6 years in a post-disaster context and to analyze how classroom-based psychosocial interventions support emotional stabilization and educational reintegration. A descriptive qualitative design was employed in a kindergarten functioning as a child-friendly psychosocial support setting. Data were collected through participatory classroom observation, semi-structured interviews with caregivers and educators, and children’s expressive activities, including drawing and symbolic play. Thematic analysis was conducted to identify patterns of trauma expression and changes in learning engagement. Findings indicate that trauma was primarily expressed through non-verbal behaviors, including regression, separation anxiety, sleep disturbances, hyperarousal, and reduced attention span, which interfered with structured classroom participation. Play-based and expressive strategies integrated into daily routines facilitated emotional regulation, peer interaction, and gradual re-engagement in learning activities. Recovery was most effective when family involvement and consistent caregiver–teacher collaboration supported classroom routines. The study highlights the importance of trauma-informed, developmentally appropriate practices embedded within early childhood education settings to promote both psychological recovery and educational continuity in post-disaster contexts. </em></p>2026-07-15T14:44:43+07:00Copyright (c) 2026 Journal La Eduscihttps://newinera.com/index.php/JournalLaEdusci/article/view/3286The Effect of a Motivation-Based STAD Learning Model on Students’ Academic Achievement in Mathematics and Science2026-07-15T15:54:07+07:00Partono Siswosuharjopartonosiswosuharjo@stmikmbanten.ac.idAl-Bahra Al-Bahraalbahra@raharja.infoAndri Cahyo Purnomoandricahyo@raharja.infoEwin Sucianasucianaewin@gmail.com<p><em>This study examined the effectiveness of a motivation-based Student Teams Achievement Division (STAD) learning model on junior high school students' academic achievement in mathematics and science in Banten Province, Indonesia.

This study investigated the production and substitution patterns of the English voiceless labiodental fricative /f/ among Sundanese EFL student teachers in Banten. A qualitative case study design supported by descriptive frequency analysis was employed. The participants were 12 undergraduate English Education students aged 20–21 years who regularly used Sundanese in daily communication and had completed pronunciation and phonetics courses. Data were collected through two oral-reading recording sessions using 30 isolated words and 22 sentences containing English labiodental fricatives. The analysis focused on 78 occurrences of /f/ in initial, medial, and final word positions. The recordings were transcribed using the International Phonetic Alphabet, classified according to their phonetic realizations and phonological environments, and validated by two expert raters. The findings showed that /f/ was substituted with the voiceless bilabial stop [p], voiced labiodental fricative [v], voiced velar stop [g], and voiceless velar stop [k]. The substitution of /f/ with [p] was the most frequently identified pattern. These substitutions occurred across different word positions and were influenced by surrounding sounds and orthographic forms, particularly words containing <ph> and <gh>. The findings highlight the need for explicit pronunciation instruction focusing on articulatory features, phonological environments, and English sound–spelling relationships.</em></p>2026-07-16T11:09:28+07:00Copyright (c) 2026 Journal La Edusci
