Abstract

This study aims to determine the improvement of students' mathematical literacy skills through the application of the Realistic Mathematics Education (RME) approach compared to Teacher Centered Learning (TCL), and to analyze the interaction between the learning approaches and students' Adversity Quotient (AQ) levels. The method used was a quasi-experiment with subjects of grade VIII students at SMP IT Nurul Fadhilah Percut Sei Tuan. The research instruments included an Adversity Response Profile (ARP) questionnaire and a mathematical literacy test. The results showed an increase in mathematical literacy skills in students who learned using the RME approach, with an N-gain of 0.589 higher than the class using TCL. This study also found an interaction between the learning approach and AQ levels on students' mathematical literacy skills. Students in the climbers category showed better resilience and ability in solving mathematical problems than students categorized as campers or quitters. This finding confirms that the application of contextual learning such as RME with strengthening non-cognitive aspects such as AQ, has an important role in improving students' mathematical literacy.

Abstract

Students’ understanding of cube and cuboid concepts has not yet been optimally achieved, as the learning process tends to be teacher-centered and does not sufficiently involve students actively. This condition indicates the need for a learning model that not only actively engages students but also provides meaningful learning experiences. This study was conducted to examine the implementation of the Project-Based Learning (PjBL) model in supporting the conceptual understanding of Grade VIII students at SMP Negeri 34 Medan on the topic of cubes and cuboids. The research employed a qualitative descriptive approach, with the research subjects consisting of 26 Grade VIII students and one mathematics teacher. Data collection techniques included observation, interviews, documentation, and analysis of lesson plan (RPP) documents. Data analysis was carried out qualitatively through the stages of data reduction, data presentation, and conclusion drawing. Based on the research findings, the implementation of the Project-Based Learning (PjBL) model was proven to help students improve their conceptual understanding. This was indicated by students’ ability to explain concepts in their own words, relate concepts to real-life situations, and correctly apply surface area and volume concepts. Therefore, Project-Based Learning can be considered an alternative mathematics learning model that is active, contextual, and student-centered.

Abstract

This study aims to describe the learning conditions of functions and analyze the effectiveness of GeoGebra-assisted Discovery Learning in improving high school students' conceptual understanding. The study used a descriptive qualitative method, with data collection techniques including classroom observations, interviews with mathematics teachers, and documentation of 32 eleventh grade students. The results indicate that the use of GeoGebra increased student engagement through dynamic and interactive graphic visualizations, helping students explore the relationship between function equations and graph changes more clearly. Students appeared more active in discussions, were able to articulate conceptual reasoning, and demonstrated improvements in interpreting graphical and algebraic representations. The stages of Discovery Learning and the teacher's role as a facilitator also contributed significantly to the effectiveness of the learning. Overall, the integration of GeoGebra has been shown to support deeper conceptual understanding and has positive implications for the development of technology based mathematics learning.
