Students’ Use of Multiple Solution Strategies to Find the Angle Between Two Intersecting and Non-perpendicular Lines

Abstract

This paper reports a study on students' use of three solution strategies in learning to find the angle between two intersecting and non-perpendicular straight lines. The study sought to investigate whether low-performing Grade 12 students' use of multiple solution strategies had an effect on their test scores in finding the angle between two intersecting non-perpendicular lines. Seventeen low-performing students from a secondary school in a Province in South Africa participated in the study. A repeated measures research design approach was employed and data were collected using an achievement test. Quantitative analysis of results using one-way repeated measures analysis of variance (RM ANOVA) indicated significant differences instudents' scores due to the strategies used. We therefore recommend that students be exposed to multiple solution strategies to finding the angle between two lines.

Desain Pembelajaran Sudut Menggunakan Konteks Rumah Limas Di Kelas Vii

“…Asih&Suciptawati (2014) juga menyatakan bahwa sudut merupakan salah satu materi yang diiujikan pada Ujian Nasional. Selain itu, aplikasi sudut juga dapat digunakan pada bidang-bidang teknik, arsitektur, astronomi, geologi dan fisika (Machisi, 2014).…”

“…Selain itu, pembelajaran sudut di kelas dapat juga dilakukan dengan cara pengukuran menggunakan busur (Fyhn, 2008;Menon, 2009;Machisi, 2014 (Keiser, 2004). Siswa kurang tertarik dan kurang termotivasi sehingga menyebabkan siswa kesulitan dalam membedakan jenis-jenis sudut serta menghitung besar sudut (Safitri, 2012).…”
