The research conducted aims to determine the ability of students in solving physics problems using Polya's theory and the difficulties experienced in solving problems. The method used is quantitative with a descriptive approach. The research subjects were 15 students of class VIII SMP Negeri 2 Tambolaka City. Data collection using test instruments in the form of essay questions and interviews to students. The results showed that, the ability of students in solving physics problems was in the high category 26%, moderate 7%, low 47% and very low 20% while aspects of student ability based on Polya's stages are students who understand the problem in the problem 10 students, plan the problem in the problem 9 students, carry out planning in the problem 8 students, look back at the answers in the problem 6 students. Thus the ability of students in grade VIII SMP Negeri 2 Tambolaka city is in the low category in solving physics problems. At the stage of understanding the problem and planning the problem some students have been able to solve it, but at the stage of carrying out the planning and rechecking the answers there are still many students who experience errors in solving it. The difficulties experienced by students are in determining equations, remembering magnitude and units, and calculating complex numbers.

This study aims to analyze the influence of work motivation, work discipline, and work environment on teacher performance at SMP Negeri 1 Wewewa Barat. Teacher performance is widely recognized as a key determinant of educational quality and student achievement. It is shaped by various internal and external factors, including psychological, behavioral, and organizational aspects. To examine the complex relationship among these factors, a quantitative approach was employed using path analysis, allowing for both direct and indirect effect testing. Data were collected through structured questionnaires distributed to all teachers at the school, making it a population study with 20 respondents. The findings from the F-test reveal that work motivation (X₁), work discipline (X₂), and work environment (X₃) collectively exert a significant influence on teacher performance (F = 18.761; sig. = 0.000). However, results from the partial test (t-test) show that only work motivation has a statistically significant individual impact (t = 7.468; sig. = 0.000), while the other two variables do not. Following model trimming to refine the regression equation, the final model retained only work motivation as a significant predictor, resulting in a coefficient of determination (R²) of 0.756. These results highlight the central role of motivation in shaping teacher performance, with 75.6% of performance variability explained by motivational factors alone. Therefore, educational stakeholders are encouraged to prioritize policies and practices that cultivate intrinsic motivation among teachers, such as recognition systems, professional development, and supportive school cultures. The study provides valuable implications for improving educational outcomes through evidence-based teacher management strategies

Provinsi Nusa Tenggara Timur merupakan salah satu provinsi di Indonesia yang memiliki banyak daerah tertinggal, terdepan, terluar, salah satunya adalah Kabupaten Sumba Barat Daya (SBD), sebuah kabupaten yang terletak di Pulau Sumba. Masyarakat setempat memiliki infrastruktur yang sangat terbatas seperti listrik dan air bersih. Desa Lete Wungana di Kabupaten Wewewa Tengah merupakan salah satu wilayah SDB yang tidak memiliki akses listrik. Seiring dengan rencana pembangunan sarana prasarana seperti PLTS dan program lain untuk mengembangkan pelayanan pendidikan dan kesehatan masyarakat, masyarakat Desa Lete Wungana memerlukan program pelatihan pemberdayaan untuk mempersiapkan mereka menerima dan memanfaatkan infrastruktur tersebut secara keberlanjutan. Oleh karena itu, kegiatan pengabdian masyarakat dilakukan untuk membangun dan memperkuat kapasitas masyarakat lokal dengan menggunakan pendekatan active citizens yang dikembangkan oleh the British Council. Kegiatan ini dibagi menjadi tiga tahapan: perekrutan, pelatihan, dan pendampingan. Kegiatan ini, khususnya tahapan pelatihan berfokus pada dialog, refleksi, dan kerja sama agar masyarakat setempat dapat menjadi agen perubahan di desanya. Pelatihan selama empat hari ini telah memberikan dampak nyata dalam pengembangan soft skills para peserta yaitu dengan menumbuhkan kesadaran sosial mereka dan mendukung mereka untuk berperan aktif dalam membangun komunitas yang lebih baik. Para peserta diberdayakan untuk mengembangkan kepercayaan diri, pengendalian diri, dan keterampilan berdialog serta termotivasi untuk menciptakan perubahan sosial yang positif di komunitas mereka.

The study aims to investigate the effect of implementing the Problem Based-Learning (PBL) model on students’ learning outcomes in science subject matter, specifically cell introduction, for Grade VIII Students at SMP Gloria Dei Wee Kura. The research employed a quasi-experimental method with a Pre-test and Post-test Control Group Design. The subject consisted of 22 students divided into two classes: 11 students in the experimental calss and 11 students in the control calss. The research instrument was a multiple-choice test consisting of 14 items that had been tested for validity and reliability. Data collection was conducted through Pre-test and Post-test, while data analysis was carried out using the non-parametric Mann-Whitney U Test with the assistance of SPSS version 16.0. The results showed a significant difference in learning outcomes beetwen the experimental class and the control class, a significance value of 0,000 < 0,05. This finding demonstrates that the application of the Problem Based-Learning (PBL) model has a positive effect on students’ learning outcomes in the science topic of Cell Introduction for Grade VIII at SMP Gloria Dei Wee Kura.

Student learning outcomes in science subjects often experience problems such as low learning outcomes due to the application of conventional learning models. This makes students passive and learning boring and non-contextual. To overcome this problem, one model that can be used is the experimental model, which is expected to improve student learning outcomes by actively involving them in the learning process directly. The purpose of this study was to determine the effect of the experimental method on student learning outcomes on the material on changes in the state of matter in class VII of junior high school. The type of research used was quasi-experimental research with a pretest-posttest control group design. There were 27 students in the study, with 14 students in the experimental class and 13 students in the control class. The research instrument was a multiple-choice test consisting of 20 questions that had been tested for validity and reliability. Data collection techniques were carried out through pretest and posttest, while data analysis used the Mann-Whitney U Test non-parametric test with the help of SPSS version 16.0. The results showed a significant difference in learning outcomes between the experimental class and the control class with a significance value of 0.000 < 0.05. This proves that the application of the experimental method has an effect on student learning outcomes in class VII on the material on changes in the state of matter.

Critical thinking skills are essential 21st-century competencies that need to be developed in science education. This study aims to analyze the critical thinking skills of grade VIII students in a junior high school on human respiratory system topics. This research employed a qualitative descriptive method involving 27 students. The research instruments consisted of an essay test developed based on Ennis's critical thinking indicators (basic clarification, bases for a decision, inference, advanced clarification, and strategies and tactics) as well as semi-structured interviews with six students selected through purposive sampling. Data analysis was conducted using the Miles and Huberman model, which includes data reduction, data display, and drawing conclusions. The results showed that the majority of students possessed critical thinking skills in the low category: 22 students (81.48%) were in the low category, 3 students (11.11%) in the moderate category, and 2 students (7.41%) in the high category. These findings emphasize the need for implementing innovative learning strategies to enhance students' critical thinking skills in science learning.
