Abstract

This research investigates the impact of project-based learning (PjBL) on enhancing students’ creative thinking abilities through a comprehensive meta-analytic study. Creative thinking is recognized as an integral part of higher-order thinking skills (HOTS) required for success. Employing the preferred reporting items for systematic reviews and meta-analyses (PRISMA), studies published between 2014 and 2024 were identified and synthesized from the Scopus database. Data analysis, conducted with R, assessed the impact of PjBL using effect size (ES) measurements. The findings demonstrate that PjBL significantly improves creative thinking skills compared to traditional teaching methods. Moderator analysis revealed that variables such as educational level, subject area, and learning model influence the outcomes, with the highest impact observed in high school and inquiry-driven subjects like physics. Variations of PjBL, including technology-enhanced models, such as Google Classroom-based approaches, further amplified its effectiveness, particularly in virtual learning environments. This study highlights PjBL’s adaptability and robust potential in fostering creativity and innovation across diverse educational contexts. The results provide practical implications for educators in designing tailored PjBL strategies to cultivate students’ creative thinking, emphasizing the importance of interdisciplinary approaches and technological integration in modern education.

Abstract

Effective teaching and improved learning outcomes rely on student engagement and active learning. Interactive, hands-on approaches are particularly valuable in science education for fostering better comprehension of scientific concepts. This research investigates the efficacy of the drill and practice method to enhance student engagement and learning outcomes in salt hydrolysis. The study follows a classroom action research design across two cycles in a public high school in Sukoharjo Regency, Indonesia. Participants were selected purposively due to iden­tified issues in engagement and academic performance. Data collected via cognitive tests, obser­vations, and questionnaires were analyzed descriptively. Results show that implementing the drill and practice method significantly heightened student engagement in salt hydrolysis, with active student percentage rising from 73% (Cycle I) to 88% (Cycle II). Cognitive learning outcomes also improved, progressing from 67% (Cycle I) to 81% (Cycle II). These findings hold significance for science education. The drill and practice approach enhances engagement and understanding, allowing educators to elevate learning outcomes. This method can cultivate engagement and boost learning in similar contexts, such as high school. By embracing interactive strategies, educators foster active participation, aiding students in mastering scientific concepts and addressing engage­ment and performance concerns

Abstract

Online distance learning during the COVID-19 outbreak presents new challenges and opportunities for teachers and students. The Blended Learning method is reported to be one of the promising alternatives. However, no specific study revealed the proper blended learning model for chemistry learning that require chemistry representation and can improve critical thinking and problem solving skills at high school level. Qualitative research using phenomenological methods was used in this study. The data collection technique used is using questionnaires, interviews, and documentation. A total of 22 respondents from master students of chemistry education, lecturers and teachers of chemistry education participated in this study. The blended learning model analyzed in this study are Rotational blended learning models (station class, Lab/Whole Group class, flipped class, and Individual), Flex, Self-Blend, and Enriched-Virtual classes. The study results indicate that the blended learning model that the respondents chose the most suitable for multiple representation-based chemistry learning was the Flipped Class model (50%), while the one that was not selected was the Individual Rotation model.

Abstract

Recently, research on the chemistry of natural products as medicinal has been increasingly developed; this is because natural products have many chemical components, have the potential biological activities without side effects, and are easy to obtain. One of these natural products is Lempuyang Emprit (Zingiber amaricans BL.) essential oil. The researchers guided UKM Suti Sehati to develop a new product: a hand sanitizer containing Lempuyang Emprit essential oil (LEEO). This study aims to make ten hand sanitizer formulas by varying LEEO concentrations and determine the best formula based on the physical properties and antibacterial activities. The best formulation obtained was then optimized with variations in fragrance concentration. The best product was selected by a hedonic test using 30 untrained panelists based on the parameters of color, scent, texture, pH, homogeneity, speed of drying, causing no red skin, causing no pain, and causing no dry skin. The antibacterial activity tests were performed against Staphylococcus aureus ATCC 25923 and Escherichia coli ATCC 25922 using the disk method. The LEEO isolation was carried out using steam and water distillation methods, and the chemical components of the best product was identified using the GC-MS method. Based on the hedonic test, the best hand sanitizer product contains 1.5% LEEO and 3% fragrance. This product has a strong antibacterial activity value against S. aureus ATCC 25923, with an inhibition zone of 15.95 mm, and a moderate value against E. coli ATCC 25922, with an inhibition zone of 9.42 mm. The hand sanitizer product contains 21.35% of Zerumbone and exhibits antibacterial and antioxidant capabilities.
