Abstract

Carbon tetrachloride (CCl₄) is widely used to induce experimental oxidative liver injury through the generation of free radicals that promote lipid peroxidation and hepatocellular damage. Natural products with antioxidant properties are being explored for their potential to mitigate such injury. This study aimed to evaluate the dose-responsive ameliorative effects of Channa striata extract on hepatic oxidative stress and histopathological alterations in rats following subacute CCl₄ exposure. Thirty male Wistar rats were divided into five groups: normal control (K1), CCl₄ control (K2), and three treatment groups receiving C. striata extract at 100, 150, and 200 mg/kg body weight/day for two weeks after six weeks of CCl₄ induction (K3–K5). Hepatic malondialdehyde (MDA) levels were measured as an indicator of lipid peroxidation. Liver histopathology was assessed for hepatocellular necrosis, congestion, and inflammatory cell infiltration using a semi-quantitative scoring system. CCl₄ exposure significantly increased hepatic MDA levels and caused severe histopathological damage in the control group. C. striata extract dose-dependently attenuated MDA levels (p < 0.001), with the 200 mg/kg/day group showing the lowest levels (2.80 ± 0.15 vs. 6.65 ± 0.13 nmol/g in CCl₄ control). Histopathological scores for necrosis, congestion, and inflammatory infiltration ameliorated progressively with increasing doses, with median total scores improving from 8.5 (CCl₄ control) to 2.0 (200 mg/kg/day). Channa striata extract demonstrates dose-dependent ameliorative activity against established CCl₄-induced oxidative liver injury, as evidenced by attenuation of lipid peroxidation and mitigation of histopathological damage. Further studies incorporating serum liver enzymes and molecular mechanisms are warranted.

Abstract

This study aims to analyze the influence of the integration of Local Ecological Knowledge (LEK) in science learning on the understanding of the concept of frog metamorphosis and environmental literacy of elementary school students in urban areas. This study uses a quantitative approach with a pre-experimental design of a one-group pretest-posttest involving 30 elementary school students. Data were collected through concept comprehension tests and environmental literacy questionnaires, then analyzed using the N-Gain and ANCOVA tests. The results showed that the average score of concept understanding increased from 56.20 in the pretest to 82.10 in the posttest (N-Gain = 0.59), while the environmental literacy score increased from 60.35 to 85.40 (N-Gain = 0.63). The results of the ANCOVA test showed that the integration of LEK had a significant effect on concept understanding (F = 18.42; p < 0.001; η² = 0.39) and environmental literacy (F = 21.17; p < 0.001; η² = 0.42). These findings show that LEK-based learning is able to improve conceptual understanding and environmental literacy through the association of science materials with the local environmental context. Thus, the integration of LEK is an effective approach to support contextual and sustainable science learning in primary schools.

Abstract

This study investigates the effect of the Flipped Classroom model assisted by Moodle on student learning independence and academic outcomes in physics, specifically regarding Newton's Laws. A quasi-experimental design with a pretest-posttest control group was employed, involving 75 tenth-grade students. The experimental group utilized the Moodle-integrated flipped approach, while the control group received conventional instruction. Data were analyzed using MANOVA, normalized gain, and Pearson correlation. The results indicate that the integrated model significantly improves both variables. The experimental group achieved a moderate increase in learning independence (normalized gain = 33%) and a high increase in learning outcomes (normalized gain = 73%), outperforming the control group (15% and 63%, respectively). Furthermore, a moderate positive correlation was found between learning independence and academic achievement. In conclusion, leveraging Moodle within a flipped classroom framework effectively fosters student autonomy and enhances cognitive mastery in physics education.

Abstract

This study aimed to develop and evaluate a web-based Numerical learning media oriented toward Problem-Based Learning (PBL) to enhance junior high school students' Numerical problem-solving skills. Utilizing the Plomp research and development model, the final prototype was field-tested involving 25 eighth-grade students. The results demonstrated a classical effectiveness rate of 76%, categorizing the developed media as effective. Specifically, students exhibited exceptional proficiency in understanding the problem (93.33%) and planning a solution (88.44%). However, a significant cognitive deficit emerged in the final phase of checking the results (48.89%). It is concluded that while embedding PBL syntax into a web-based environment effectively scaffolds the forward procedural steps of Numerical problem-solving, it currently falls short in internalizing metacognitive reflection. To bridge this gap, future digital Numerical learning architectures must transcend passive information delivery by integrating interactive mechanisms, such as automated reflective prompts and dynamic feedback loops, to structurally enforce self-regulated evaluation.

Abstract

Elementary school students' critical thinking skills in science learning on the topic of natural resources have not yet developed optimally because instruction tends to rely on conventional Student Worksheets (LKS) and provides limited opportunities for contextual learning. This research sought to evaluate how the STEM-Project Based Learning (STEM-PjBL) model—implemented through a project where students created natural batik dyes—enhances elementary school students' critical thinking skills regarding natural resources. The study adopted a quantitative approach, utilizing a quasi-experimental method structured around a One-Group Pretest–Posttest Design. The sample consisted of 26 fifth-grade students from a public elementary school in Cirebon City, Indonesia, selected through purposive sampling. Data were collected using a critical thinking skills test, a student response questionnaire, and classroom observations. The data were analyzed utilizing the Shapiro–Wilk test, the Wilcoxon Signed Rank Test, N-Gain analysis, and descriptive statistics. The results showed that the mean pretest score increased from 77.02 to 81.54 on the posttest. The Wilcoxon Signed Rank Test demonstrated a statistically significant difference, showing a significance value of 0.001 (p < 0.05), indicating that the model yielded a highly consistent and uniform improvement across the sample. However, the overall N-Gain score was 0.20 (20%), which belongs to the low category, suggesting that while the positive impact of the model was statistically robust, the short-term duration of the intervention limited the total magnitude of the score increase.
