Abstract

The Curriculum in Indonesia has two elements in science learning, namely understanding science which is related to high-level thinking skills and process skills as an effort to hone thinking skills in investigation or research. In science learning, process skills that can be assessed are known as science process skills. Student need to have Science Process Skills (SPS) as preparation for facing the realities of life, so that student s are trained to think logically to solve problems.  The research aims to measure students mastery of science process skills in general and differences in mastery of science process skills based on gender in mixed compound element material in class VIII SMP IT Dar El Iman Padang. This research is quantitative research with a descriptive survey. The sample selection used a total sampling technique, namely 4 classes. Data collection techniques were carried out by assessing student worksheets and written tests. The research results show that students’ mastery of science process skills has varying averages. The lowest mastery of SPS indicators is the hypothesis indicator with a percentage of 36,9% in the poor category and the highest indicator is the prediction indicator at 85.7% in the very good category. Based on gender, female students SPS mastery is better with a percentage 69.7 % in good category than male students with a percentage 58.0% in sufficient category. Overall, students mastery of science process skills is categorized as good at 63,3%.

Abstract

This research was driven by the observation that many students still lack a strong understanding of the subject matter, leading to below-average performance. Another factor that causes low student learning outcomes is the lack of variety in learning models applied by teachers so that learning becomes uninteresting. For this reason, various learning models are needed, such as the application of the guided discovery learning model The results of previous research stated that this model can improve student learning outcomes. This study aims to determine the effect of the application of the guided discovery learning model on students’ learning outcomes. This type of research is a quasi experiment with a nonequivalent control group design research design. The sampling technique uses the purposive sampling technique. The sample consists of one experimental class by applying the guided discovery learning model and one control class with a conventional model. This study conducted a statistical analysis using Microsoft Excel. The result shows that there is an improvement in students’ learning outcomes in the control class in the low category, while the increase in students’ learning outcomes in the experimental class is in the medium category.

Abstract

Scientific literacy is recognized as one of the essential competencies required for students to address the challenges of the twenty-first century, including rapid scientific and technological development and increasingly complex global issues. However, the 2018 Programme for International Student Assessment (PISA) reported that Indonesian students' scientific literacy remains below the international average. This study aimed to describe the scientific literacy levels of eighth-grade junior high school students. A quantitative descriptive research design was employed involving 222 eighth-grade students from a public junior high school during the 2022/2023 academic year. Data were collected using a scientific literacy test consisting of multiple-choice, complex multiple-choice, matching, and true–false items. The test assessed three scientific literacy competencies: explaining scientific phenomena, evaluating and designing scientific investigations, and interpreting scientific data and evidence, within the topic of Substances Pressure and Its Applications in Everyday Life. The data were analyzed using descriptive statistics. The results indicated that students achieved an average score of 41.48% for explaining scientific phenomena (moderate category), 66.32% for evaluating and designing scientific investigations (good category), and 50.00% for interpreting scientific data and evidence (moderate category). Overall, the findings suggest that the scientific literacy of eighth-grade students remains at a moderate level, indicating the need for instructional strategies that further promote scientific reasoning and inquiry-based learning.
