Abstract

21st-century education demans learning that enchances knowledge and develops communication skills. This study aims to analyze the need for developing an integrated ethnoscience-based E-LKPD on global warming, using a Problem-Based Learning (PBL) model to facilitate students’ knowledge acquisition and communication skills. The preliminary study was conducted at SMAN 1 Enam Lingkung, involving two physics teachers and 32 tenth-grade students in Phase E. A descriptive statistical analysis method was employed, utilizing questionnaire data, written performance assessments, and documentation of Mid-Semester Assessment (MSA) scores. The results show that the learning process still relies on conventional media and has not yet incorporated ICT effectively. Students demonstrated low levels of knowledge (average 42.59%) and communication skills (average 41.29%). Furthermore, teachers have not optimally integrated the ethnoscience approach and the PBL model into their instruction. Based on these findings, an E-LKPD design was developed as an innovative solution to enhance the quality of 21st-century learning, particularly in delivering contextual and meaningful content on global warming.

Abstract

This study aims to analyze the water absorption capacity of open land within the UHAMKA East Jakarta campus as an indicator of soil permeability. The methods used were the gravimetric method to measure soil water content and the infiltration method using a cylindrical tube to calculate the water infiltration rate. Samples were taken from three different locations, and the parameters observed included temperature, soil pH, post-oven humidity, and absorbed water volume. The results showed that each sample had varying physical and chemical characteristics. Samples with the highest humidity and lowest pH showed high permeability, while drier and neutral soils had lower permeability. This variation reflects differences in soil pore structure and organic content between locations. This study provides an initial overview of the potential of open land as a natural infiltration medium to support sustainable water management in urban campus environments.

Abstract

This study reported a systematic literature review (SLR) of pedagogical innovations on nano-teaching in science education. Nano-teaching, a streamlined pedagogical approach involving brief teaching episodes (5–10 minutes) followed by immediate feedback, has emerged as a transformative strategy in science education. This systematic review synthesizes 53 peer-reviewed studies from 2014 to 2024 to explore the applications of nano-teaching, impacts, and challenges. Findings of the literature review highlighted its efficacy in enhancing teacher preparation, student engagement, and conceptual understanding of complex scientific concepts. The review includes a comparison of nano-teaching and microteaching, delineates teacher and student roles and provides both a general textual model and a specific sequence for implementing nano-teaching in cyber classrooms. Challenges such as time constraints, scalability, and teacher resistance are addressed, with recommendations for curriculum integration, professional development, and technology-enhanced delivery. This comprehensive analysis underscores nano-teaching’s potential to revolutionize science education while identifying avenues for future research.

Abstract

This study aims to design teaching materials that combine ICT and cover the topics of alternative energy, as well as ethno-PBL. The main purpose of creating these teaching materials is to help students understand better and improve their knowledge and creative thinking skills. This study uses descriptive statistical analysis, with data collected through questionnaires, student daily test scores and performance assessments. This study revealed five main findings from the needs analysis including; First, the context analysis of teaching materials for physics learning is still low, with an average score of 42.5. Second, the use of local science in the material is still low, with an average of 40. Third, it shows that the PBL model is not well integrated in the teaching materials, with an average of 48. Fourth, it shows that students' ability to understand the material is still lacking with an average of 34.22. Fifth, creative thinking skills are also still low, with an average of 34.61. The results obtained indicate that the development of ICT-based teaching materials integrated with Ethno-PBL is very much needed by teachers and students to improve students' knowledge and creative thinking skills.

Abstract

The phenomenon of light duality is a fundamental concept in modern physics that states that light has a dual nature, namely as a wave and a particle. Understanding this concept often becomes a challenge in learning due to the limitations of laboratory facilities to directly observe interference and diffraction phenomena. This study aims to explore the concept of light duality through quantum interference simulations based on a virtual laboratory using PhET Interactive Simulations from the University of Colorado Boulder. The research was conducted in a descriptive-quantitative manner by varying three main parameters, namely the number of slits (1, 2, and 3), slit width (0.04–0.4 mm), and light wavelength (400–700 nm). Each configuration was systematically simulated to observe the resulting diffraction and interference patterns. Data analysis was carried out using descriptive and inferential statistics, including Shapiro-Wilk, Levene, Kruskal-Wallis tests, as well as one-way ANOVA to identify the relationship between optical variables and the characteristics of interference patterns. The research results indicate that with variations in the number and width of slits, light tends to behave like particles with concentrated intensity, whereas with variations in wavelength, the widening light-dark pattern demonstrates wave properties. These findings reinforce the concept of light duality and confirm the effectiveness of virtual laboratories as a learning medium for visually and interactively understanding complex quantum phenomena.
