Abstract

Buffer 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.

Abstract

This study aims to improve students' learning outcomes on the topic of salt hydrolysis through the implementation of the Problem Based Learning (PBL) model with a differentiated instruction approach. The focus of the study is to accommodate students' varying levels of learning readiness through process and content differentiation, designed based on initial assessment results. This classroom action research was conducted in two cycles in class XI.4 of SMAN 1 Palembang, involving 39 students during the 2024/2025 academic year. Each cycle consisted of four stages: planning, action implementation, observation, and reflection, following the Kemmis & McTaggart model. The instruments used included student worksheets (LKPD) as formative assessments and summative tests to evaluate learning outcomes. The results show that the application of PBL with a differentiated approach successfully enhanced students’ academic performance. In the pre-cycle stage, five students had not yet achieved the minimum mastery criteria (KKM). After implementing process differentiation in cycle I, student mastery improved significantly, although one student remained below the threshold. Subsequently, content differentiation was applied in cycle II, resulting in all students achieving mastery. The average score increased from 92.46 in cycle I to 96.75 in cycle II. Thus, a differentiated approach based on initial assessments proved effective in enhancing students’ learning outcomes more equitably and optimally.
