Abstract

Reaction rate is a conceptually layered chemistry topic because students must coordinate observable phenomena, particle-level explanations, symbolic equations, graphs, and mathematical processing of experimental data. This study aimed to describe the profile and distribution of learning difficulties across six reaction-rate subtopics among Grade XI male students in an Islamic boarding-school setting. A quantitative descriptive design was employed with 82 students at Nurul Hakim Islamic Boarding School, Kediri, West Lombok. Data were collected using a 25-item achievement test covering: reaction-rate concepts and collision theory; factors affecting rate; rate laws and reaction orders; determination of order and the rate constant; graphs and energy diagrams; and applications in daily life and industry. Difficulty percentage was calculated as one minus the ratio of the mean score to the maximum score. The overall difficulty level was 45%, classified as moderate. The highest difficulty occurred in determining reaction order and the rate constant from experimental data (63%, high), followed by rate laws and reaction orders (50%, moderate). The lowest difficulty was found in basic reaction-rate concepts and collision theory (30%, low). At the individual level, 59 students (71.95%) were in the moderate-difficulty category and 23 students (28.05%) were in the low-difficulty category. These findings indicate that students' main barrier lies not in recalling basic concepts but in coordinating proportional reasoning, variable control, and symbolic calculations. Instruction should therefore prioritize scaffolded analysis of experimental tables, explicit links among macroscopic, submicroscopic, and symbolic representations, and guided practice in determining reaction orders and rate constants.

Abstract

The training of preservice physics teachers to participate in educational research is a long-standing issue in physics teacher education. This investigation seeks to understand the effectiveness of a focused seminar course in facilitating research readiness across time and by performance-based assessment and analysis of a research portfolio. Twenty-six preservice physics education students attended a semester-long seminar course focusing on research problem identification, critical response to SINTA and Scopus indexed journals articles, proposal development, and academic communication. The growth in students’ development was studied using a phase-based analysis between the weekly assessment based on a Research Task Plan (RTM) and qualitative analysis of research portfolios. The answers provide evidence of a continuous development of students’ research competencies with less variation in performance over the course levels. Analysis of the portfolios also suggests a shift away from mostly descriptive engagement with research literature toward more critical and comparative disciplinary analysis. These results indicate that seminars, designed as scaffolded learning environments that are authentic can be pedagogically effective in bridging between coursework taken by undergraduates and research done independently especially in the context of physics teacher preparation.

Abstract

Problem-solving skills are an essential competency that chemistry education students must master as future educators. This study aims to analyze the effectiveness of a laboratory experiment on the formulation of liquid soap enriched with hibiscus flower extract (Hibiscus rosa-sinensis L.) in developing students’ problem-solving skills. The research design employed a pre-experimental approach with a one-group pretest-posttest design involving 15 fifth-semester chemistry education students at Mandalika University of Education. The learning intervention was designed based on contextual problems through six stages: orientation to formulation problems, extraction of bioactive components from hibiscus flowers, design of liquid soap formulas, implementation of manufacturing procedures, testing of product quality parameters, and reflective evaluation based on empirical data. The measurement instrument consisted of a structured essay test that assessed six problem-solving indicators: problem identification, conceptual analysis, solution planning, implementation strategies, data interpretation, and critical evaluation. Data analysis utilized the Shapiro-Wilk normality test, paired t-test, normalized gain, and Cohen’s d effect size. The results showed a significant increase in problem-solving scores from a mean of 50.4 (SD=10.2) to 85.6 (SD=7.8), with a t-value (14)=4.26, p<0.001. An N-gain value of 0.71 indicates a high category, with an effect size of d=1.10 indicating a large practical impact. An applied chemistry context based on household products has proven effective in bridging the gap between theoretical knowledge and real-world applications in chemistry education.

Abstract

Bath soap is a hygiene product widely used by the public, with demand for safe, high-quality natural soaps continuing to rise. This study aims to analyze the effect of adding rose flower extract (Rosa damascena Mill.) on the quality of coconut oil-based bath soap, as assessed by physicochemical and organoleptic parameters. The experimental study employed a completely randomized design with four treatments of rose flower extract concentrations: 0% (control), 3%, 6%, and 9%, each with three replicates. The soap was produced via the cold saponification method using coconut oil as the base material, with the addition of sodium hydroxide, distilled water, and rose flower extract obtained through maceration in 70% ethanol for 3×24 hours. The quality parameters tested included pH, moisture content, foam height, foam stability, homogeneity, texture, color, aroma, and panelist acceptance. Data were analyzed using one-way ANOVA and Duncan’s post-hoc test at a significance level of ?=0.05. The results showed that the addition of rose flower extract significantly affected all soap quality parameters (p<0.05). The treatment with a 6% concentration produced soap with optimal quality: pH 9.2 ± 0.3, moisture content 18.4 ± 1.2%, foam height 8.6 ± 0.4 cm, foam stability 82.3 ± 2.1%, excellent homogeneity, soft texture, attractive pink color, strong characteristic rose aroma, and the highest panelist acceptance (score 4.2 ± 0.3 on a 5-point scale). A higher extract concentration (9%) resulted in a hard texture and an overly dark color, which the panelists found less appealing. Coconut oil-based bath soap with 6% rose flower extract meets the SNI 06-3532-2016 standard and has the potential to serve as a high-quality natural soap alternative with added aesthetic and aromatherapeutic value.

Abstract

This narrative review synthesizes recent literature to explore the significant role of Project-Based Learning (PjBL) as a catalyst for innovation through the development of creative thinking among students. Drawing from a comprehensive review of studies, this paper examines how PBL frameworks, by engaging learners in authentic, complex problem-solving and hands-on project creation, inherently foster environments conducive to divergent thinking, novel idea generation, and critical problem analysis. We analyze the pedagogical mechanisms within PjBL, such as collaboration, inquiry-based learning, and iterative design, that contribute to enhancing students' creative abilities across various educational levels and disciplines, including STEM and engineering. Furthermore, the review discusses the documented effectiveness of PjBL in improving not only creative thinking skills but also related competencies like critical thinking and self-efficacy, which are vital for innovation. The findings underscore PjBL's potential to equip students with the necessary cognitive tools to navigate and contribute creatively to an ever-evolving world. This review aims to consolidate current understanding and highlight future research directions for optimizing PjBL implementation to maximize its impact on fostering innovation-driven creative thinking.

Abstract

Teacher Training Institutions (LPTK) play a strategic role in transforming educational quality through community service. This article aims to analyze the trends of learning innovation within LPTK service programs in Indonesia during the 2019-2023 period. Based on a literature review of 38 selected references, a significant shift in the mentoring paradigm was identified. Initially, community service focused on classical approaches such as Lesson Study, Classroom Action Research (CAR), and conventional media development. However, driven by post-pandemic demands, the trend has shifted towards establishing comprehensive digital literacy ecosystems. These innovations include the integration of Artificial Intelligence (AI), Augmented Reality (AR), Learning Management Systems (LMS), and digital parenting programs. The analysis reveals that LPTKs are no longer solely focused on teachers' technical skills in the classroom but are actively building synergy between schools, families, and technology to create a sustainable digital learning ecosystem.
