Abstract

The increasing use of smartphones among early childhood populations has raised concerns regarding its impact on children’s development and behavior. Therefore, this study analyzes the dynamics of smartphone addiction among young children in Padang City, Indonesia, using the CSAR (Children–Susceptible–Addicted–Recovered) model. Population data and smartphone usage statistics from 2021 to 2024 were incorporated into the modeling process, while parameter estimation was conducted using a genetic algorithm with six mutation-rate variations. The best estimation result produced an error rate of 3.3646%, indicating a strong agreement between the model and empirical data. The basic reproduction number (R₀) of 0.6156 places the system in the moderate category. This suggests that although the spread of smartphone addiction among young children in Padang City is currently under control and not self-sustaining, continuous monitoring and strengthened preventive measures remain necessary to anticipate potential increases in future cases. Sensitivity analysis reveals that the transmission of addictive behavior through social interaction is the most influential factor affecting changes in R₀. These findings highlight the importance of managing peer-group interactions, such as limiting shared digital activities and strengthening collaborative non-digital play, as effective preventive strategies. Numerical simulations further support these results by demonstrating the system’s tendency toward an addiction-free equilibrium. Overall, this study provides a solid theoretical and empirical foundation for policy formulation and future research on early childhood digital behavior.

Abstract

Background: Raudhatul Athfal (RA) teachers often face challenges in developing effective teaching modules aligned with the Merdeka Curriculum due to limited training and difficulties in translating curriculum principles into classroom practice. Aims: This community service aims to strengthen RA teachers’ capacity in developing teaching modules based on the Merdeka Curriculum. Methods: This program employed a Participatory Action Research (PAR) approach through mentoring activities conducted offline over two days. The program involved 52 RA teachers in a series of activities including material delivery, hands-on module design, and reflective discussions. Data were collected through observations, interviews, focus group discussions (FGDs), and questionnaires. Result: The results indicate a significant improvement in teachers’ understanding and skills in developing teaching modules aligned with the Merdeka Curriculum. Teachers demonstrated better comprehension of curriculum structure, learning outcomes (CP), and the formulation of learning objectives (TP) and teaching modules (ATP). In addition, their ability to design structured and contextualized modules improved, particularly in aligning learning activities with student needs and integrating appropriate learning media. The evaluation results showed a high level of participant satisfaction, with an average score of 3.95 categorized as “Good,” indicating that the mentoring activities were well-received. Teachers also showed increased confidence in implementing the curriculum in classroom practice, including the use of technology. Furthermore, the participatory and hands-on approach enabled active engagement, leading to deeper understanding and improved practical skills. Conclusion: The mentoring program effectively enhanced RA teachers’ capacity in designing innovative and contextualized teaching modules aligned with the Merdeka Curriculum, making it a practical and replicable model for similar educational programs.

Abstract

Background: Improving the professional competence of early childhood teachers is essential to ensure the quality of learning and child development outcomes. However, many teachers still face challenges in pedagogical skills, curriculum development, and the integration of digital media in learning. These conditions indicate the need for structured, practice-oriented training supported by field mentoring. Aims: This program aims to enhance early childhood teachers’ professional competence through a practice- and mentoring-based advanced training program. Methods: This program employed a Service Learning approach, integrating training, practical experience, and community-based application. The implementation consisted of three stages: preparation, implementation, and evaluation. The program involved 50 early childhood teachers in Padang Panjang. Activities included in-class training, independent practice assignments, field mentoring, local learning visits, and dissemination activities. Evaluation was conducted through pre- and post-tests, observation, and assessment of participants’ performance. Data were analyzed descriptively. Results: The findings show improvements in teachers’ competencies, including understanding of child development, learning strategies, curriculum design, assessment practices, and the use of digital media. Participants also demonstrated enhanced ability in lesson planning, developmental assessment, and implementing innovative learning. Mentoring and field-based activities strengthened practical skills and confidence. Conclusion: A practice- and mentoring-based advanced training program effectively improves teachers’ professional competence. The integration of training, practice, and mentoring provides meaningful and sustainable learning outcomes and can serve as a model for similar programs.
