Abstract

Stunting is a malnutrition condition in children under five, characterized by delayed growth and inappropriate height. Environmental factors, such as nutrition, digestive infections, low birth weight, and poor environmental sanitation, indirectly impact the health of children under five, affecting their nutritional status. This research aims to determine the level of knowledge, ownership of toilets, and hand washing habits as factors for preventing stunting in the working area of the Ampibabo Community Health Center. The study used an analytical observational research with a case-control design, with 70 respondents consisting of mothers of babies and toddlers. The results showed a relationship between knowledge, latrine ownership, and hand washing habits and stunting incidence in babies and toddlers. This suggests that community health centers should provide regular and continuous assistance to cadres in providing education about stunting prevention at all levels of society, especially those without family toilets and without soap-washing habits.

Abstract

Training and mentoring in the development of TPACK-based learning devices were conducted at SD Inpres 3 Talise. The training participants are 16 elementary school teachers. The training is conducted by administering an initial test, followed by the presentation of training materials. The next step is the mentoring in the preparation of learning devices, where participants are given a final test and a questionnaire to gather their responses to the training and mentoring activities. Data from the pre-test and post-test were processed using the N-gain formula and N-gain interpretation categories. The results of the participant response questionnaire showed that 93.75% of teachers prepared well for the training and mentoring, 93.75% of the training materials were relevant to the teaching profession, and 100% of the participants expressed that the training and mentoring were very beneficial for teachers. The results of the data analysis showed that all participants experienced an improvement in test scores, with 1 person showing an increase of g > 0.70, 3 ≤ g ≤ 0.7 (high category) and 15 other participants with an increase of 0.3 ≤ g ≤ 0.7. (kategori sedang). Based on the interpretation of N-gain effectiveness, with an increase in N-gain value >76, it can be said that the training and mentoring in the preparation of TPACK-based learning devices were effectively carried out by the service team from Tadulako University.

Abstract

Science education in junior high school plays a crucial role in developing students' scientific thinking, particularly in understanding global issues like global warming. This study aims to assess the scientific thinking abilities of seventh-grade students at three state junior high schools in Palu City, using a descriptive approach and a test based on seven aspects of scientific thinking as defined by García-Carmona (2023). The findings reveal that approximately 80% of students showed progress in scientific thinking, with 12% achieving a competent level and 8% remaining in the beginner category. However, their understanding of scientific information from discourse and graphics averaged only 26%. Overall, students demonstrated developing scientific thinking skills, which could enhance their comprehension of scientific concepts, especially related to everyday experiences and environmental issues shared on social media. The role of teachers is essential in guiding students to understand and critically evaluate scientific information, such as articles on global warming. The study recommends developing interactive, problem-based teaching strategies to further improve students' scientific thinking skills. Future research should explore the role of media technology, teachers, and parents in supporting the development of scientific thinking regarding natural phenomena to advance science education in Palu and its surrounding areas.

Abstract

This study aims to develop a differentiated teaching module based on students' learning styles in the Project-Based Learning of Natural and Social Sciences (IPAS) to improve collaboration skills. The research employed a Research and Development (R&D) approach using the ADDIE model, which includes five phases: analysis, design, development, implementation, and evaluation. The subjects of the study were Grade X students at SMK Negeri 1 Parigi, with 19 students from the Akuntansi dan Keuangan Lembaga (AKL) program as the experimental class and 19 students from the Desain Pemodelan dan Informasi Bangunan (DPIB) program as the control class. Research instruments included expert validation sheets, practicality questionnaires, cognitive assessment tests (pretest and posttest), and observation sheets for collaboration skills. Validation results showed that the module achieved a validity level of 83%, categorized as valid. The module’s practicality was rated at 92% by teachers and 95% by students, both classified as highly practical. Regarding effectiveness, a comparison of posttest scores between the experimental and control groups yielded a Cohen’s d of 0.93, indicating a large effect on students’ cognitive outcomes. Additionally, within the experimental group, a comparison of pretest and posttest collaboration scores resulted in a Cohen’s d of 0.89, also classified as a large effect. These findings demonstrate that the differentiated teaching module effectively enhances students’ 21st-century skills, particularly collaboration.

Abstract

The objective of this study was to develop and assess the impact of Wizer E-LKPD on the problem-solving skills and ecological attitudes of 28 VIIC class students at SMP Negeri 1 Wita Ponda. The study employed the ADDIE model as its research framework and utilized a one-group pretest-posttest design with purposive sampling. The research instruments included validation sheets, response questionnaires completed by teachers and students, tests of problem-solving abilities, and an ecological attitude questionnaire. The findings indicated that Wizer E-LKPD was highly valid, with an average rating of 94.12%. The results demonstrated that the Wizer E-LKPD effectively enhanced problem-solving skills, achieving a medium effect size of 0.65, and improved ecological attitudes with a simple effect size of 0.30. Therefore, it can be concluded that the Wizer E-LKPD is a valid, practical, and effective tool for improving students' problem-solving abilities and fostering ecological attitudes in science learning at SMP Negeri 1 Wita Ponda.

Abstract

This study aims to measure and analyze the level of STEM literacy among prospective physics educators using Rasch measurement theory. A quantitative approach with a descriptive design was employed. The research instrument consisted of a STEM literacy test comprising multiple-choice questions and essays, and the data were analyzed using Winstep software version 5.7.1 to assess the validity and reliability of the measurement instrument. The results reveal that only a small number of prospective physics educators exhibit very high STEM literacy, while the majority demonstrate moderate to low levels of competencies and attitudes toward STEM literacy. The measurement instrument was confirmed to be valid and reliable according to Rasch parameters. These findings highlight the need for targeted interventions to enhance digital literacy, multidisciplinary skills, technology integration, and scientific competence among aspiring educators. Educational institutions are thereby urged to better prepare future educators to teach and promote STEM literacy effectively among students.
