Abstract

Students' critical thinking skills are still relatively low, despite the importance of these skills in facing the challenges of the 21st century. This study aims to explore the effect of the Problem-Based Learning (PBL) model on enhancing students' critical thinking skills, considering the level of interpersonal intelligence. The research uses a posttest-only treatment by level (2 x 2) design, with the dependent variable being critical thinking skills, and the independent variables including the learning model (PBL and conventional) and interpersonal intelligence (high and low). The sample consists of 144 eighth-grade students from two public junior high schools in West Jakarta, selected using cluster random sampling technique. The results show that students taught with the PBL model exhibited better critical thinking skills than those taught with the conventional model. Furthermore, students with high interpersonal intelligence demonstrated superior critical thinking skills compared to those with low interpersonal intelligence. The study also identifies a significant interaction between the learning model and interpersonal intelligence, where students with high interpersonal intelligence who received PBL instruction showed the best critical thinking outcomes. In conclusion, the PBL model has been proven to significantly improve critical thinking skills, especially in students with high interpersonal intelligence. These findings provide guidance for educators to consider students' characteristics when selecting the appropriate teaching model to support the development of their critical thinking skills.

Abstract

Many researchers found that students had difficulty in understanding probability material. Students mostly focus on applying formulas to find solutions to problems without knowing what the concept is and why the formula works. This underlies the researcher to design probability learning as a hypothetical learning trajectory. The study aims to describe a series of learning activities designed to build relational understanding skills in probability material. This study uses a design research method consisting of three stages, namely preparation and design, teaching experiment, and retrospective analysis. Data collection techniques were carried out using a video recorder, documentation, and test questions. The data collected is in the form of qualitative data. The collected data is interpreted by peers, teachers, and supervisors to reduce the subjectivity of the researcher's point of view. All data that has been collected were analyzed retrospectively. The results of the research conducted showed that students experienced an increase and gave a good response in solving problems. Teachers are expected to use a learning design with a realistic mathematical approach because it helps students understand learning and apply their knowledge in everyday life.

Abstract

The beauty of Istiqlal Mosque is reflected through its architectural design. The decorative arts that adorn this mosque are generally found in elements such as doors, windows, walls, gates, and vents, which show special patterns. Such patterns can be identified through the concept of geometric symmetry, specifically Frieze Patterns and Wallpaper Patterns. The Frieze pattern is a subgroup within a symmetry group formed through one-way translation, creating a linear pattern that repeats in one direction. There are seven types of frieze patterns, each formed through a combination of specific isometries. Along with that, there are also other geometric patterns known as wallpaper patterns. Wallpaper patterns analyze patterns based on transformations on a flat plane and have seventeen types. This study aims to explore and explain geometric patterns based on Frieze Patterns and Wallpaper Patterns contained in the decorative arts of Istiqlal Mosque. Data collection methods involve observation and documentation. The results showed that there are certain frieze patterns in the Istiqlal Mosque, such as the type . Meanwhile, the wallpaper patterns identified in the design of the Istiqlal Mosque are type pmm and pmg. It is important to note that not all designs in the decorative arts of Istiqlal Mosque can be categorized into seven frieze patterns as well as seventeen wallpaper patterns.

Abstract

This study aims to identify students’ misconceptions in solving Higher Order Thinking Skills (HOTS) geometry problems on plane figures. A descriptive qualitative approach using Cognitive Error Analysis was applied to the written responses of 10 eleventh-grade students in the Mathematics Cambridge Program. The validated instrument consisted of three HOTS essay items. Data were analyzed through error classification, mapping to HOTS levels (C4, C5, C6), and in-depth diagnosis of responses identified as misconceptions. The findings show that students’ main difficulties lie in the Analyzing stage (C4), which subsequently weakens their ability to evaluate and create strategies (C5–C6). Two dominant patterns emerged: misreading non-routine instructions and errors in fundamental geometric concepts, with several cases indicating independent weaknesses at C6. These results highlight the need to strengthen strategic analysis as the foundation for HOTS development. The study is limited by its small sample size and reliance on written data.
