Abstract

This study aims to determine the role of statistics in everyday life to help students understand the concept of data centering measures, especially the mean, median and mode. This research was conducted at MTS Aisyiyah Palembang. The research subjects were class VIII students, involving 16 students who were divided into 3 groups. This research used the PMRI approach where students were invited to measure contextually their height. The results showed that the PMRI approach can help students discover for themselves how to calculate a person's height and find the mean, median and mode through a mathematical reference process. Finding their own concept of data centering measures and solving problems in everyday life related to the concept of data centering measures. The results of this study show that through a series of activities that have been carried out help students in learning the size of data concentration.

Abstract

Mathematics learning plays an essential role in developing students’ logical, systematic, and analytical thinking skills. One of the higher-order thinking abilities that serves as a main focus in mathematics education is mathematical reasoning. This ability is closely related to the process of mathematical proof, which functions to justify the truth of a statement logically. This study aims to examine the relationship between the understanding of proof concepts and the development of mathematical reasoning among junior high school students through a library research approach. Data were obtained from various sources such as textbooks, journal articles, research findings, and relevant educational documents. The analysis was conducted using the content analysis method to review both conceptual and empirical findings from the literature. The results indicate that understanding the concept of proof not only helps students comprehend the logical structure of mathematics but also contributes to the development of deductive and reflective reasoning skills. Engaging in proof activities enables students to shift from merely imitative reasoning toward independent logical construction (creative reasoning). However, teaching proof at the junior high school level still faces several challenges, such as students’ limited understanding of basic logic, time constraints, and the lack of teacher training in teaching proof effectively. Therefore, learning strategies that emphasize students’ thought processes, provide opportunities for exploration, and integrate proof activities into meaningful learning contexts are needed.
