An Analysis of Buffer Solution Topics in Chemistry Textbooks: Application of the 4 Step Teaching Material Development Criteria
Get PDFBuffer solution content in Chemistry textbooks plays a significant role in achieving these educational objectives. This study aims to analyze buffer solution material in class XI Chemistry textbooks using the 4S TMD selection criteria, focusing on curriculum consistency, concept accuracy, and value education. A qualitative evaluative approach was employed, comparing the data collected from two textbooks (Book A and Book B) against established standards. The evaluation covered the scope and depth of the material, the accuracy of concepts, and the integration of values. The analysis found that both textbooks included six relevant concept labels, though Book B contained one overly general label. Regarding concept depth, Book A had two concepts with insufficient depth, while Book B had one overly shallow concept and one excessively detailed. Both books achieved the standard for concept accuracy. For value education, Book A integrated six core values, such as discipline and responsibility, while Book B incorporated eleven values, including creativity, democracy, and honesty. The findings suggest that Book A aligns more closely with the 4S TMD evaluation criteria than Book B. This highlights the importance of balancing curriculum alignment, conceptual depth, and value integration in educational materials

Integrating Dilemma Stories into Chemistry Learning: Analyzing Students' Critical Thinking Skills
Get PDFCritical thinking is a key competency for 21st-century students, essential for logical reasoning, decision-making, and academic success. However, studies indicate that Indonesian students often exhibit low levels of critical thinking. Chemistry, particularly topics like oxidation-reduction reactions, offers real-life applications, such as waste oil disposal, that can be leveraged to improve these skills. This study aims to analyze the effectiveness of integrating dilemma stories into project-based learning (PBL) to enhance students' critical thinking skills in the context of oxidation-reduction reactions. The study was conducted at SMAN 77 Jakarta with 36 students from Class X Mathematics and Natural Science 2. A qualitative approach was used, with data collected through observations, reflective journals, interviews, and critical thinking tests. The integration of dilemma stories in PBL was implemented through five stages: value reflection, problem-solving, project development, monitoring and evaluation, and transformation. The findings indicate significant improvements in students' critical thinking, creativity, collaboration, and problem-solving skills. Based on test results, students achieved level 3 (Acceptable) in critical thinking. The approach also enhanced their understanding of chemical concepts and awareness of addressing real-world problems. The integration of dilemma stories within PBL has proven effective in fostering critical thinking and other 21st-century skills in chemistry learning. This approach can serve as a model for innovative educational practices in STEM subjects
