Abstract

This study is a descriptive-correlational study. The objectives of this study are to determine: 1) the level of critical thinking skills among eighth-grade students at public junior high schools throughout the Panakkukang subdistrict; 2) the level of problem-solving skills among eighth-grade students at public junior high schools throughout the Panakkukang subdistrict; 3) whether there is a relationship between critical thinking skills and problem-solving skills among eighth-grade students at public junior high schools in the Panakkukang subdistrict. The population for this study consists of all eighth-grade students at public junior high schools in the Panakkukang subdistrict for the 2025/2026 school year, totaling 587 students. Sampling was conducted using simple random sampling, with a sample size of 168 students. The research instruments consisted of a critical thinking test comprising 15 questions and a problem-solving test comprising 15 questions. Data were collected by administering the tests in person. The data were analyzed using descriptive and inferential statistical techniques. Based on the analysis results, it can be concluded that: 1) The level of critical thinking skills among eighth-grade students at public junior high schools in the Panakkukang subdistrict falls into the very low category, with a score of 49.96. 2) The problem-solving skills of eighth-grade students at public junior high schools in the Panakkukang subdistrict fall into the very low category, with a score of 46.43. 3) The critical thinking and problem-solving skills of eighth-grade students at public junior high schools throughout the Panakkukang subdistrict, with a correlation coefficient of 0.732, indicating a strong correlation.

Abstract

This research is descriptive research with a survey method. The aim of this research is to determine the level of numeracy literacy skills of class VIII students at SMP IT Wahdah Islamiyah Makassar. The population of this study were all students in class VIII at SMP IT Wahdah Islamiyah Makassar, consisting of 3 classes with a total of 89 students. The sample was selected using a saturated sampling technique so that the sample was determined if all members of the population were used as samples and the total research sample was 89 students. The research instrument is a test instrument for numeracy literacy skills with 15 questions and critical thinking skills with 15 questions. The data collection technique is by administering the test directly. Data were analyzed using descriptive statistical analysis techniques and inferential statistical analysis. The results of the analysis can be concluded that the level of numeracy literacy skills is in the "low" category with an average value of 30.34.

Abstract

This research aims to: 1) determine the level of science learning outcomes of class VIII students at SMP Negeri 23 Bulukumba after being taught using virtual laboratory media 2) determine the improvement in science learning outcomes of class VIII students at SMP Negeri 23 Bulukumba who were taught using virtual laboratory media. 3) find out the science learning outcomes of class VIII students at SMP Negeri 23 Bulukumba after being taught using virtual laboratory media were higher than before being taught using virtual laboratory media. This research is a pre-experiment with One Group Pre-test Posttest Design. The population was all class VIII students at SMPN 23 Bulukumba, the sample was selected using a purposive sampling technique so that 1 class was selected with a total of 38 students. The instruments in this research were pretest and posttest in the form of multiple choice questions. Data analysis techniques are descriptive and inferential. The research results found: (1) The learning outcomes of class VIII students at SMPN 23 Bulukumba before using PhET-based computer simulation learning media had an average overall score of 20.79, which is in the very low category, (2) The learning results of class VIII students SMPN 23 Bulukukmba after using PhET-based computer simulation learning media had an average overall score of 71.84, which is in the high category (3). There were differences in learning outcomes before and after using PhET-based computer simulation learning media.

Abstract

Energy literacy is a crucial competency for pre-service science teachers, who are expected to integrate renewable energy issues into school science instruction in line with the Sustainable Development Goals (SDGs), particularly SDG 4 (Quality Education) and SDG 7 (Affordable and Clean Energy). This study examined changes in energy literacy among pre-service science teachers who took part in SDG-oriented integrated STEM learning built around a mini solar-panel (solar cell) project, and assessed the validity of the learning module and instruments and the practicality of the implementation. A pre-experimental one-group pretest-posttest design without a comparison group was used with 35 pre-service science teachers enrolled in the Matter and Energy course. Energy literacy was measured with an expert-validated instrument consisting of 20 knowledge items (cognitive dimension; true/false or multiple-choice), 9 attitude statements (affective dimension; 5-point Likert scale), and 7 self-reported energy behavior statements (behavioral dimension; 5-point Likert scale). The STEM-based Matter and Energy module and the energy literacy instrument were rated highly valid (84.2% and 90.2%), and the implementation across three consecutive meetings was in the practical category (77.6%, 77.6%, and 80.0%). The average energy literacy score increased from 62.97% (pretest) to 80.69% (posttest), with a normalized gain (N-gain) of 0.48 (medium category). The largest gain was in the cognitive dimension (N-gain 0.85; high), followed by the behavioral (0.50; medium) and affective (0.18; low) dimensions. Paired differences were statistically significant in all dimensions (p < 0.001), with large effect sizes. Participation in the learning was associated with an improvement in energy literacy, particularly in conceptual knowledge, whereas the smaller affective change suggests that attitudes may need longer and more sustained instruction. Because the design had no control group, the improvement cannot be attributed to the intervention alone, and the findings should be regarded as preliminary
