Abstract

This study investigates the use of experimental statistical analysis as an instructional approach to enhance students’ understanding of variable relationships in science learning. Many students tend to memorize experimental results without comprehending the underlying relationships between variables, resulting in limited analytical reasoning and superficial understanding. To address this issue, the present study explores how integrating basic statistical tools-such as mean, correlation, and regression-into experimental activities can strengthen conceptual comprehension, analytical reasoning, and scientific literacy. Grounded in constructivist and inquiry-based learning frameworks, the research emphasizes active engagement, where students participate in data collection, analysis, and interpretation to draw evidence-based conclusions. The study employed a quasi-experimental design involving science students divided into experimental and control groups. Both groups conducted similar laboratory experiments, but only the experimental group received explicit instruction in statistical analysis. Data were collected through pre-tests and post-tests to measure changes in students’ understanding of variable relationships. The results indicated a 25% improvement in the experimental group’s comprehension and reasoning ability compared to the control group. Students who applied statistical analysis demonstrated greater proficiency in interpreting data, identifying causal patterns, and connecting theoretical knowledge to experimental findings. In contrast, students taught through traditional narrative-based instruction showed minimal gains and relied heavily on memorization. The findings highlight the effectiveness of integrating statistical reasoning in promoting critical thinking, problem-solving, and scientific reasoning skills.

Abstract

Activated carbon has been developed for supercapacitor electrode material due to their high degree of micro porosity and large surface area. The carbon source, preparation conditions such as temperature and atmosphere, and preparation method strongly influence the crystalline structure and the properties of carbon materials. This article is focused on the crystalline structure analysis of bamboo and coconut coir activated carbon The bamboo and coconut coir carbon were fabricated by using pyrolysis method. The activated bamboo carbon and activated coconut coir carbon were produced using a chemical activation method where H3PO4 solution as activator agent. Characterization of the physical/crystalline structure of the bamboo carbon (BC), and coconut coir carbon (CCC) and bamboo activated carbon (BAC), coconut coir activated carbon (CCAC) was determined using XRD measurement. The XRD spectra of BC and BAC indicate that the percentage crystallinity are 29.1%, and 18.4% respectively. For CCC and CCAC the percentage crystallinity are 11.3% and 13.2%, respectively. The interlayer spacing (dhkl) for BC is 4.05 Angstrom, and for BAC is 3,79 Angstrom. The crystallite height (Lc) for BAC is 6.64 Angstrom and for BC is 21.56 Angstrom. The interlayer spacing (dhkl) for CCC and CCAC are the same 4.05 Angstrom. The crystallite height (Lc) for CCAC is 4.96 and for CCC is 2.83 Angstrom.

Abstract

This study investigates the effectiveness of the Guided Inquiry Learning (GIL) model in enhancing students' scientific literacy, particularly in the domain of energy and its transformation. The primary aim of the research was to assess the impact of GIL on students' understanding of complex scientific concepts related to energy, focusing on energy types, transformations, and the conservation law. The GIL model, characterized by active learning, student-centered inquiry, and structured guidance, was implemented through hands-on experiments, observations, and collaborative discussions. The results of the study revealed a significant improvement in scientific literacy, with a 25% increase in post-test scores. The findings suggest that GIL fosters greater student engagement and critical thinking compared to traditional lecture-based methods. Students demonstrated increased confidence and a deeper understanding of energy concepts, making connections between theoretical knowledge and real-world applications. Despite challenges such as time constraints and resource limitations, these obstacles were addressed by adjusting schedules and incorporating virtual simulations to enhance the learning experience. Student feedback was overwhelmingly positive, with participants expressing appreciation for the hands-on nature of the model and the opportunities for peer learning. This study underscores the effectiveness of GIL in improving scientific literacy and suggests that its application could extend to other scientific topics, providing a flexible framework for fostering inquiry and understanding in various educational contexts. Future research is recommended to explore the long-term impact of GIL on other science disciplines and evaluate its broader applicability across different educational settings.
