Abstract

Angle trisection is a geometry concept that refers to the splitting of an angle into three equal parts, so that each part formed has the same angle size. This angle trisection became one of the three most interesting and unsolved mathematical problems during the last three centuries BC. Consequently, the purpose of this study is to examine the history of angle trisection in the Thales-Euclid era and measure students' ability to solve angle trisection problems. This research is a qualitative research that uses case study and literature review methods with data collection techniques through tests and interviews. The research subjects were selected by purposive sampling method from three high school students. Furthermore, the data obtained were analyzed descriptively and qualitatively with triangulation techniques. The purpose of this analysis is to ensure that the data obtained from various sources are valid. The results showed the extent of students' understanding in responding and creating how to solve this angle trisection using a ruler and a period. A detailed presentation of the categories of answers given by learners will be presented in this paper.Keywords–Angular Trisection, Thales-Euclid Era, History of Mathematics

Abstract

Promiscuity is an increasingly worrying social phenomenon, including among elementary school children. The socialisation of promiscuity prevention at the elementary school level is crucial for building a strong character foundation from an early age. This study aims to improve students' understanding of promiscuity and identify effective strategies for preventing promiscuity in elementary school children. The qualitative research method involved all students at SDN 19 Koto Baru. Data was collected through observation and questioning and analysed using thematic and meta-review methods. The results showed that the majority of students had gained basic knowledge about the dangers of promiscuity, although there were still concerns about peer pressure. These findings provide an important insight for strengthening character education programmes in schools and supporting the role of the family in preventing deviant behaviour from an early age. Therefore, this study recommends that teachers optimise interactive teaching methods, parents increase dialogue and supervision at home, and schools routinely organise socialisation programmes to create a positive social environment conducive to forming strong moral values.
