Abstract

Effective chemistry learning should be designed to actively engage students in various activities that promote deep understanding of abstract concepts, skill enhancement, and positive behavior development. This study aimed to develop creative content based on a website as a learning media for molecular geometry topics. This study uses the ADDIE development model (Analysis, Design, Development, Implementation, and Evaluation). The study involved 32 students at the high school, 5 educators, and 3 validators. The results show that 100% of the validators stated that the content developed on the website is valid. The developed content aligns with the material concept, and the learning objectives are based on the needs and expected learning outcomes. Feasibility test results indicate that the website meets the criteria for facilities and media quality, aligning with standards for an ideal learning platform. Therefore, it can be concluded that the creative website-based content developed for molecular geometry is highly suitable and can increase students engagement in the learning process and understanding of abstract chemical concepts.

Abstract

Numeracy skills in the context of science are crucial in helping students understand and interpret scientific phenomena quantitatively. However, there has been no comprehensive review of students' numeracy skills in the context of science in secondary schools, particularly in the Bandung area. This study aims to describe the level of numeracy skills in the context of science and identify areas of student weakness. The method used is descriptive quantitative, involving 121 11th-grade students from several schools. Students who had taken science subjects (physics, chemistry, and biology) in 10th grade were assessed on numeracy skills covering five numeracy domains: arithmetic, algebra, data processing, graphing, and geometry. The data were analyzed descriptively using mean values, standard deviations, and minimum and maximum score ranges. These findings indicate that students' numeracy skills are generally in the moderate to low category, with a wide distribution of scores. Data processing is the domain with the highest success rate, while arithmetic received the lowest average score of the five numeracy domains. Strengthening in arithmetic operations is also needed to calculate decimals, ratios, fractions, and percentages. These results indicate the need to integrate numeracy content into science learning to strengthen students' numeracy skills.

Abstract

This study addresses the limited integration of Discovery Learning, a Hess’s Law Enthalpy Change Determination Simulator, and student worksheets (LKM). These components have generally been implemented separately or in different combinations in previous studies, and simulation-based learning in Hess’s Law remains limited. The study aimed to examine students’ conceptual understanding of Hess’s Law, both overall and across specific learning objectives, after implementing the Discovery Learning model integrated with a Hess’s Law Enthalpy Change Determination Simulator and student worksheets. The research employed a pre-experimental one-group pretest–posttest design involving 29 senior high school students. Data from the conceptual understanding test were analyzed using descriptive and inferential statistics. The paired-sample t-test revealed a statistically significant improvement from 35.06 to 63.22 (t= −8.11, p < 0.001). At the level of specific learning objectives, the Wilcoxon signed-rank test showed that students achieved greater gains in inferring Hess’s Law from comparisons of reaction pathways than in determining enthalpy change based on Hess’s Law. These findings indicate that the instructional approach was associated with improved conceptual understanding of Hess’s Law. This study suggests that integrating Discovery Learning with a Hess’s Law Enthalpy Change Determination Simulator and structured worksheets may support students’ conceptual understanding of Hess’s Law and serve as a practical instructional strategy in chemistry education.

Abstract

Pembelajaran teori asam basa memerlukan media yang mampu memvisualisasikan konsep abstrak dan meningkatkan keterlibatan peserta didik. Penelitian ini bertujuan melakukan pengembangan lanjutan media pembelajaran interaktif berbasis website pada submateri teori asam basa melalui penyelarasan aktivitas dalam media dengan tahapan Predict-Observe-Explain (POE), perangkat pembelajaran, serta fitur media. Metode penelitian yang digunakan adalah development research dengan mengadaptasi model pengembangan ADDIE (Analysis, Design, Development, Implementation, dan Evaluation). Data diperoleh melalui lembar validasi ahli serta angket tanggapan pendidik dan peserta didik yang dianalisis secara deskriptif kuantitatif. Hasil penelitian menunjukkan bahwa pengembangan lanjutan dilakukan dengan mengubah platform media dari aplikasi berbasis smartphone (Android) menjadi berbasis website, mengintegrasikan sintaks Predict-Observe-Explain (POE) melalui penambahan aktivitas Predict berbasis video pada materi teori Arrhenius, serta menyempurnakan navigasi dan beberapa fitur media. Hasil validasi ahli menunjukkan bahwa media memperoleh persentase kelayakan sebesar 83,75% dengan kategori sangat layak, kemudian disempurnakan berdasarkan masukan validator sebelum dilakukan uji coba terbatas. Selanjutnya hasil uji coba terbatas menunjukkan bahwa media memperoleh persentase tanggapan sebesar 100% dari pendidik dan 97,03% dari peserta didik yang keduanya termasuk dalam kategori sangat baik. Dengan demikian, media pembelajaran interaktif berbasis website hasil pengembangan lanjutan layak digunakan sebagai alternatif media pembelajaran pada submateri teori asam basa.

Abstract

In determining the reaction rate between hydrochloric acid (HCl) and sodium thiosulfate (Na₂S₂O₃), conventional experiments commonly rely on visual observation of sulfur turbidity, making endpoint determination highly dependent on lighting conditions and observer judgment. These limitations reduce measurement accuracy, repeatability, and objectivity, highlighting the need for an alternative Data Acquisition System (DAS) capable of providing continuous quantitative measurements. This study focuses on the development and optimization of a Data Acquisition System (DAS) utilizing transducers and photodetectors through the Research Science Design (RSD) approach as an alternative method for reaction kinetics analysis. The experimental setup consisted of a borosilicate reactor enclosed in a black acrylic chamber to minimize ambient light interference, equipped with 3 W high-power LEDs (green, blue, and white) as light sources and a Mini Mixer interface integrated with MGA software for continuous data acquisition. Each LED configuration was evaluated through three experimental repetitions, and the recorded signals were analyzed using Relative Standard Deviation (RSD) to assess measurement stability and determine the optimum light source. Based on the evaluation results, the DAS was capable of (1) continuously recording sulfur colloid formation in real time, (2) demonstrating the highest measurement stability under green light with an RSD of 1.18%, and (3) eliminating observer-dependent visual bias. The proposed system provides a simple, coding-free, objective, and affordable solution for improving the quality and efficiency of reaction kinetics measurements in chemistry education.
