Abstract

The demands of 21st-century education require students to possess higher-order thinking skills (HOTS) to deeply and critically understand concepts in facing the complexities of the modern world. This study aims to systematically review the relationship between critical thinking skills and students’ concept mastery through a systematic literature review (SLR). The method involved selecting and analyzing ten relevant journal articles published within the last ten years. The findings indicate that critical thinking skills play a significant role in enhancing students’ concept mastery. Furthermore, innovative learning strategies such as Problem-Based Learning (PBL), Project-Based Learning (PjBL), Concept Mapping, and Virtual Laboratory were consistently found effective in developing both variables. These strategies improve students’ abilities in analysis, synthesis, and evaluation, thereby strengthening comprehensive conceptual understanding. This review provides important implications for educators and curriculum developers to integrate learning approaches that stimulate critical thinking skills to achieve optimal concept mastery in the context of 21st-century education.

Abstract

Science concept mastery is an important aspect of learning because it plays a crucial role in enhancing students’ ability to understand and apply scientific knowledge. However, in practice, science concept mastery remains a common challenge due to the dominance of conventional, teacher-centered instructional approaches. This study aims to examine various learning models used to improve students’ science concept mastery, identify the most dominant learning model, and analyze the distribution of research based on educational level, science subject matter, and the dependent variables investigated. The research employed a literature review method involving 16 national and international journal articles published between 2016 and 2025, analyzed using the PRISMA approach. The findings indicate that guided inquiry is the most widely implemented learning model and demonstrates consistent effectiveness, particularly in physics and integrated science learning at the senior high school level. In addition, Problem-Based Learning (PBL) and Project-Based Learning (PjBL) serve as effective supporting models in connecting science concepts to real-life contexts and fostering higher-order thinking skills. These findings emphasize the importance of implementing inquiry-oriented and student-centered learning models to enhance students’ mastery of science concepts.

Abstract

Lombok has become one of the leading tourist destinations, especially with the development of the Mandalika Special Economic Zone. One of the cultural products that has the potential to be offered to tourists is Lombok traditional weaving. The study aims to analyze the effect of the pH of the dye solution on the characteristics of the dyed fabric. The research method uses a mechanical thermal method to obtain anthocyanin powder extraction, standard staining methods namely mordan, staining, and fixation, as well as characterization using tensilons, Color Analyzer software, Hooloovoo, and Encycolorpedi website. The extraction of anthocyanin compounds from teak leaves (Tectona grandis) was successfully carried out by mechanical thermal method. Color analysis and identified color changes are significantly affected by differences in solution pH. The higher the pH used, the darker the color will be produced and the higher the level of color fading in the fabric. The smallest  E value is at pH 6 =5.364 and the largest  E value is at pH 14 = 17.145. However, an increase in pH tends to increase the tensile strength of the fabric. However, the optimum tensile strength condition was obtained in a solution of pH 12, which was 17.414 MPa, while at pH 13 and pH 14, the tensile strength of the fabric decreased to 16.071 MPa. Based on the analysis of the influence of pH of dye solution on fabric tensile strength, it was identified that a 6th-order polynomial model (determination coefficient R2 = 0.9479) was identified as accurate enough to model the influence of pH on fabric tensile strength. Therefore, this finding has potential in the textile industry, especially in increasing the economic value of Lombok weaving.
