Abstract

Metacognitive skills are one of the skills needed in the 21st century to achieve student learning success. Student’s metacognitive skills are still low, so that need to be empowered during the learning process by implementing Problem Based Learning Strategy Integrated with Reading Questioning Answering (PBLRQA). Through the PBLRQA strategy, students can control their cognitive processes by planning, monitoring, and evaluating to solve problems in chemistry learning. The aim of this research was to determine the effectiveness of the PBLRQA strategy on students’ metacognitive skills on acid-base materials. The method was used quasi-experiment with a non-equivalent control group design. The sample in this study were students of class XI IPA 1 as the experimental group and students of class XI IPA 5 as the control group, with each class including 32 students. Instruments Metacognitive Activities Inventory (MCA-I) developed by Cooper and Sandi-Urena (2009) were used in this research. Data analysis was assisted by IBM SPSS Statistic 22 software. The results of this research indicated that the use of PBLRQA strategy on acid-base materials was able to empowering students’ metacognitive skills.

Abstract

Scientific literacy, particularly environmental science competency, is essential for enabling students to understand and respond to contemporary environmental challenges. However, research on chemical science literacy in Islamic senior high schools (madrasah), especially in suburban regions, remains scarce — particularly studies linking the Fundamental Laws of Chemistry to the PISA 2025 environmental science competency framework. This study aimed to identify the level of chemical science literacy of 578 students from State Islamic Senior High Schools in Bogor Regency using a quantitative descriptive survey. Data were collected through a 40-item science literacy test based on the PISA 2025 framework, assessing three indicators: explaining human interactions with Earth systems, evidence-based environmental decision making, and respecting diverse perspectives in socio- ecological crises. Results showed students achieved a high overall level of chemical science literacy. The highest achievement was explaining human interactions with Earth systems, while evidence-based decision-making was the lowest. These findings imply that chemistry teachers should integrate inquiry-based and socio-scientific strategies into instruction, and that curriculum developers should embed PISA-oriented environmental tasks to strengthen students' scientific decision-making competency.
