In spite of the ever-growing body of research in achievement goal profiles and their contribution to performance, the research on young children is quite limited. This study examined achievement goal profiles related to mathematics and literacy performance among third-grade students (N = 185, M = 8.73 years; 98 girls), using Latent Profile Analysis. Four distinct profiles emerged—Mastery-Oriented, Approach-Oriented, High Multiple-Goals, and Moderate Multiple-Goals—that were highly similar across math and literacy (contingency coefficient = 0.59). Schoolchildren endorsing the Approach-Oriented profile demonstrated higher achievement compared to those with High Multiple-Goals or Moderate Multiple-Goals profiles, which involved more avoidance goals and were less adaptive (with up to 8% of variance explained by profile). Gender differences were observed: girls were more likely to endorse profiles combining multiple goals, whereas boys more often endorsed mastery or approach profiles. These results highlight early inter-individual differences in motivational development, observable in both mathematics and literacy. Promoting adaptive goal profiles in early education may enhance academic engagement and help reduce emerging motivational disparities. Full article

Currently, teaching programming in primary and secondary schools is already standard practice in many countries. Although teaching methods and tools vary, the goal remains the same: to teach students how to program, i.e., to create appropriate algorithms for solving various tasks. In our research, we focused on the influence of personal interest and career orientation as motivation for better performance in programming and algorithm design. The main objective of the research was to determine the influence of student motivation, personal preferences, and career orientation tests on programming results. The secondary objective of the research was to verify in the practical part whether elementary school students (eighth and ninth grade) are able to program an industrial machine that they will encounter at secondary vocational schools. A structured questionnaire and an unconventional device, the PLC Logo from Siemens, were used as testing tools. Research has shown that students who have the prerequisites for studying at a technical secondary school achieve better results in programming than students who do not have these prerequisites.

School refusal behavior, defined as a child’s prolonged voluntary absence from school for reasons unrelated to illness and/or economic hardship, is a growing concern in Japan. The COVID-19 pandemic has worsened this issue by disrupting children’s lives. This review summarizes the prevalence, contributing factors, and health implications of school refusal, particularly in the context of COVID-19. A literature review of government reports and PubMed-indexed studies indicates that school refusal in Japan has been rising for eleven years, reaching a record 340,000 cases in 2023. Middle school students (6.7%) were the most affected, followed by elementary school students (2.1%). The pandemic intensified school-related, family-related, and child-related risk factors. School closures disrupted routines, reduced peer interactions, and increased social isolation, contributing to higher rates of anxiety and depression. Reports of suicides and mental health disorders among children have also surged. Family stressors, including economic hardship and parental mental health struggles, further exacerbate school refusal. Additionally, remote learning has widened socioeconomic disparities in access to education, leaving vulnerable children at greater risk. Addressing school refusal requires a multifaceted approach involving schools, families, healthcare providers, and policymakers. School-based interventions, mental health approach, and flexible educational programs would be essential. The Japanese government’s “COCOLO Plan” represents progress toward a more inclusive education system, and a comprehensive, interdisciplinary strategy is needed. Ensuring all children receive the necessary support to reengage with education is critical to overcoming the long-term challenges posed by school refusal. Full article

This study aimed to examine reading interest profiles among preservice Chinese language teachers and related factors making them begin to like or dislike reading. In total, 321 college students majoring in Chinese language education in elementary and secondary schools participated in this study and completed a reading interest questionnaire. The questionnaire contains one close-ended question asking about their reading interest levels across seven periods (from preschool to college) and three open-ended questions asking about the reasons influencing their reading interest levels. Latent profile analysis (LPA) was used to identify reading interest profiles, and qualitative analysis was used to examine factors influencing their reading interests. The LPA results revealed three profiles, namely, mountain (up-down), valley (up-down-up), and upslope (up). The qualitative analysis revealed that motivators encouraging students to read included literacy sponsors, improved reading ability, reading time, extrinsic motivators, curiosity and desire for knowledge, access to reading, discovery of preferred texts, and relief from academic stress and relaxation. By contrast, barriers associated with the decline in reading interest included academic burdens and pressure, the availability of alternatives, a lack of reading ability, a loss of reading autonomy, a lack of literacy sponsors, limited access to reading, and inappropriate texts. Literacy researchers and educators should listen to students’ voices, understand their reading experiences, and consider developing appropriate intervention programs for literacy at different periods.

Technology-enhanced learning environments are increasingly designed to promote not only knowledge acquisition but also affective and behavioral changes. This study explored how digital game-based learning (DGBL), combined with the Stage Model of Self-Regulated Behavioral Change (SSBC), can support such transformation. Focusing on environmental literacy as a target domain, fifty sixth-grade students were assigned to either a DGBL group or a web-based learning group in a quasi-experimental design. Quantitative data were collected using literacy scales measuring knowledge, sensitivity, and attitude, while qualitative insights were gathered via interviews. Our results showed that while both groups improved in terms of environmental knowledge, the DGBL group demonstrated significantly greater gains in attitudes. The interview findings revealed that the interactive storytelling and role-playing in the game promoted emotional engagement and self-reflection, aligning with the SSBC’s predecision stage. These results highlight the potential of theory-driven digital games to foster deeper cognitive–affective learning and pro-environmental behaviors among young learners. Full article

Accurately discerning the authenticity of facial expressions is crucial for inferring others’ psychological states and behavioral intentions, particularly in shaping interpersonal trust dynamics among elementary school children. While existing literature remains inconclusive regarding school-aged children’s capability to differentiate between genuine and posed facial expressions, this study employed happy and sad facial stimuli to systematically evaluate their discrimination accuracy. Parallel to behavioral measures, children’s gaze patterns during authenticity judgments were recorded using eye-tracking technology. Results revealed that participants demonstrated higher accuracy in identifying genuine versus posed happy expressions, whereas discrimination of sad expressions proved more challenging, especially among lower-grade students. Overall, facial expression recognition accuracy exhibited a positive correlation with grade progression, with visual attention predominantly allocated to the Eye-region. Notably, no grade-dependent differences emerged in region-specific gaze preferences. These findings suggest that school-aged children display emotion-specific recognition competencies, while improvements in accuracy operate independently of gaze strategy development. Full article

In the digital era, integrating technology into education is essential to meet contemporary educational demands. This systematic review examines the competencies and skills in educational technology required from in-service teachers serving in elementary, middle, and high schools, alongside the training models and methods implemented over the past decade. Following PRISMA guidelines, a systematic search was conducted in the Scopus, WOS, and ERIC databases, focusing on studies published between 2014 and 2025. A total of 82 studies were selected based on predefined inclusion criteria. The review analyzed competencies, skills, training models, and methods, identifying prevailing trends in teacher training for educational technology. The review identified seven key competencies, emphasizing skills such as using software, educational applications, and platforms, as well as virtual collaboration. The TPACK model emerged as the predominant framework for teacher training, encompassing various methods, including professional learning communities and Problem-Based Learning. A progressive and structured approach is necessary to develop teachers’ competencies, encompassing both basic technical skills and the adoption of emerging technologies. Continuous and context-specific teacher training in educational technology is critical for sustainable integration and pedagogical transformation. Barriers such as limited infrastructure and resistance to change highlight the need for strong institutional support and mentorship. Future research should aim to expand to diverse educational settings to validate and extend these findings. Full article

The purpose of this study was to analyze the impact of organizational culture on knowledge management in public elementary, secondary, and middle schools in the department of Caquetá, Colombia, based on the perceptions of managers, teachers, and administrative staff. A quantitative and correlational scope approach methodology was applied through a confirmatory factor analysis based on the use of structural equations in the SMARPLS software versión 4.0.9.7. The population under study comprised teachers, managers, and administrative staff, with a total of 362 respondents belonging to these public educational institutions. Evaluating the fundamental components of the studied constructs made it possible to show the significant influence of organizational culture on knowledge management, in which a well-structured culture takes institutional objectives that improve the processes of the creation, storage, and dissemination of knowledge into account, thus ensuring the sustainability and operational efficiency of the institution. In the specific context of the education sector, the impact and contributions of this research can be significant and timely for planning educational management in public elementary, secondary, and middle schools based on the recognized importance of knowledge management for public policy. In addition, educational institutions can be studied using theories that are usually applied in the business context, thus enhancing replicability, not only from the perspectives of education and pedagogy but also from an administrative point of view.

(1) Background: Aimed at improving school children’s motor, social, emotional, and cognitive competence (CC), the effects of physical activity (PA) have been widely investigated. However, investigations into the effects of PA during Physical Education (PE) on children’s CC have only been subject to growing interest among researchers in recent years. To bring it, the present article aims to systematically summarize the PE intervention programs whose effects on school children’s CC have been evaluated through a randomized controlled trial (RCT) design. (2) Methods: This systematic review follows the PRISMA guidelines and has been registered in PROSPERO: CRD420251083924. A systematic literature search was conducted across four electronic databases: PubMed, SCOPUS, Web of Science, and ProQuest Central. The articles were included based on the following inclusion criteria: (i) primary education children, (ii) children practicing PE, (iii) outcomes related to CC, and (iv) articles providing evaluations through RCTs. The quality assessment of all included articles was performed using the PEDro scale. (3) Results: Out of 219 initially identified studies, 25 met the inclusion criteria and were synthesized qualitatively. (4) Conclusions: The main outcomes highlighted that PE has a positive effect on primary school children’s cognitive ability, including attention, creativity, memory, academic performance, and inhibitory control. Thus, elementary school teachers are encouraged to implement these intervention programs to foster children’s CC. However, different types of interventions should be analyzed to highlight their effects on different variables of CC. Full article

In this pilot study, the crossing behavior of elementary school students commuting on bicycles was investigated with the objective of enhancing safety around pedestrian crossings within school zones. With a noticeable increase in crashes involving young cyclists near schools, this research assessed the effectiveness of visual nudges in the form of red strips displaying “CYCLISTS DISMOUNT” instructions. Initial observations indicated a lack of compliance with dismounting regulations. After the initial observations, a specific elementary school was selected for the implementation of the nudging intervention and additional pre- (N = 91) and post-intervention (N = 71) observations. The pre-intervention observations again revealed poor adherence to the regulations requiring cyclists to dismount at specific points. Following our targeted intervention, the post-intervention observations marked an improvement in compliance. Indeed, the visual nudge effectively communicated the necessity of dismounting at a critical location, leading to a higher rate of adherence among cyclists (52.74% pre-intervention, 97.18% post-intervention). Although it also indirectly affected the behavior of the accompanying adult, who more often held hands with their children while crossing, this effect was weaker than the direct effect on dismounting behavior (20.88% pre-intervention, 39.44% post-intervention). The findings of the current pilot study underscore the possible impact of nudging on behavior and advocate for a combined approach utilizing physical nudges to bolster safety within school zones. Follow-up research, including, for instance, multiple sites, long-term effects, or children traveling alone, is called for. Full article

Objectives: This study assessed the effectiveness of a cognitive behavioral therapy (CBT)-based fine dust education program, grounded in the Health Belief Model (HBM), on elementary students’ fine dust knowledge, related behaviors, and mental health (depression, anxiety, stress, sleep quality). Methods: From September to November 2024, 95 students (grades 4–6) living near a coal-fired power plant in midwestern South Korea were assigned to either an intervention group (n = 44) or a control group (n = 51). The intervention group completed a three-session CBT-based education program; the control group received stress management education. Assessments were conducted at weeks 1, 2, 4, and 8 using standardized mental health and behavior scales (PHQ: Patient Health Questionnaire, GAD: Generalized Anxiety Disorder Assessment, PSS: Perceived Stress Scale, ISI: Insomnia Severity Index). Results: A chi-square test was conducted to compare pre- and post-test changes in knowledge and behavior related to PM2.5. The intervention group showed significant improvements in seven fine dust-related knowledge and behavior items (e.g., PM2.5 awareness rose from 33.3% to 75.0%; p < 0.05). The control group showed limited gains. Regarding mental health, based on a mixed-design ANCOVA, anxiety scores significantly declined over time in the intervention group, with group and interaction effects also significant (p < 0.05). Depression scores showed time effects, but group and interaction effects were not significant. No significant changes were observed for stress, sleep, or group × PM2.5 interactions. Conclusions: The CBT-based education program effectively enhanced fine dust knowledge, health behaviors, and reduced anxiety among students. It presents a promising, evidence-based strategy to promote environmental and mental health in school-aged children. Full article

The relationship between self-rated personality and nonverbal intelligence has been studied in young students, but these studies have generally not considered nested data, despite their allowing us to analyse between-classroom variability. The present cross-sectional study involved third- to sixth-grade students (n = 447) who were nested into their classrooms (n = 32). The participants completed the Raven’s Coloured Progressive Matrices (CPM) as a measure of nonverbal intelligence and a personality questionnaire based on the Five Factor Model. At the class level, the study data included class size, class-average CPM scores, and class-homogeneity in CPM performances. Multilevel modelling with class-mean centring of personality predictors was applied to examine class-average differences in CPM scores and interaction effects between personality and class-homogeneity on CPM scores. The results showed significant differences in average CPM performances across classrooms, significant fixed and random slope effects linking nonverbal intelligence and Imagination, and a cross-level effect revealing that Imagination is a stronger predictor of CPM scores when class-homogeneity in intelligence is lower. Beyond confirming the intelligence–Imagination association generally observed in the literature, the present findings emphasise the importance of using nested structures when collecting personality and intelligence data in classrooms. More attention needs to be paid to how the classroom environment affects children’s self-reported personality and intelligence test performances. Full article

The Sustainable Development Goals (SDGs), launched by the United Nations in 2015, outline 17 interconnected objectives designed to promote human well-being and sustainable development worldwide. Education is recognized by the United Nations as a key factor in promoting sustainable development. To cultivate students with both global perspectives and local engagement, it is essential to integrate sustainability education into elementary curricula. Accordingly, this study aimed to enhance elementary school students’ understanding of the SDGs by designing a structured instructional activity and developing a hybrid digital-physical board game. The game was implemented as a supplementary review tool to traditional classroom teaching, leveraging the motivational and knowledge-retention benefits of physical board games while incorporating digital features to support learning process monitoring. To address the limitations of conventional review approaches—such as reduced student engagement and increased cognitive load—the instructional model incorporated the board game during review sessions following formal instruction. This was intended to maintain student attention and reduce unnecessary cognitive effort, thereby supporting learning in sustainability-related content. A quasi-experimental design was employed to evaluate the effectiveness of the instructional intervention and the board game system, focusing on three outcome variables: learning motivation, cognitive load, and learning achievement. The results indicated that students in the game-based Sustainable Development Goals group achieved significantly higher delayed posttest scores (M = 72.91, SD = 15.17) than the traditional review group (M = 61.30, SD = 22.82; p < 0.05). In addition, they reported significantly higher learning motivation (M = 4.40, SD = 0.64) compared to the traditional group (M = 3.99, SD = 0.69; p < 0.05) and lower cognitive load (M = 1.84, SD = 1.39) compared to the traditional group (M = 2.66, SD = 1.30; p < 0.05), suggesting that the proposed approach effectively supported student learning in sustainability education at the elementary level.

This study investigates the impact of teacher decisions and other contextual factors on indoor air quality (IAQ) in mechanically ventilated elementary school classrooms using low-cost air quality sensors. Four classrooms at a K–8 school in San Jose, California, were monitored for airborne particulate matter (PM), carbon dioxide (CO2), temperature, and humidity over seven weeks. Each classroom was equipped with an HVAC system and a portable air cleaner (PAC), with teachers having full autonomy over PAC usage and ventilation practices. Results revealed that teacher behaviors, such as the frequency of door/window opening and PAC operation, significantly influenced both PM and CO2 levels. Classrooms with more active ventilation had lower CO2 but occasionally higher PM2.5 due to outdoor air exchange, while classrooms with minimal ventilation showed the opposite pattern. An analysis of PAC filter material and PM morphology indicated distinct differences between indoor and outdoor particle sources, with indoor air showing higher fiber content from clothing and carpets. This study highlights the critical role of teacher behavior in shaping IAQ, even in mechanically ventilated environments, and underscores the potential of low-cost sensors to support informed decision-making for healthier classroom environments.

Background: Although the prevalence of dental caries in children has been decreasing in recent years, many patients still visit tertiary dental institutions with dental caries as their chief complaint. In addition, the COVID-19 pandemic that occurred around the world in 2020 may have affected the lifestyle and oral condition of children. Methods: We investigated the oral condition of new patients whose chief complaint was dental caries, and compared the results for 3 fiscal years: 2013, 2018, and 2023. The caries status was evaluated using the dmft/DMFT index. Results: The number of subjects was 129 in 2013, 163 in 2018, and 127 in 2023. The number of preschoolers in 2023 was lower than in the other years, whereas the number of elementary school students was higher, showing a statistically significant difference (p < 0.05). For the 3 years investigated, there was no change in the incidence of dental caries in primary teeth in elementary school children; however, the incidence in permanent teeth increased over time. Additionally, in the age group, the df and DMF scores were higher in 2023 than in the other years. Conclusions: At this tertiary dental institution, the number of elementary school patients, especially females, increased over the 10-year period, and the amount of dental caries in their permanent teeth also increased. It is important for dental professionals to understand this trend and focus on providing oral hygiene education to this age group. Full article
