Kemampuan Visual-Spatial Thinking Dalam Geometri Ruang Mahasiswa Universitas Kuningan

Abstract

Geometry is a branch of mathematics that is taught in school, from elementary school, high school and college. Student Mathematics Education Kuningan University in the course Geometry 3D which gained less than satisfactory achievements in the course of the geometry 3D. The ability visual thinking and spatial thinking affect learners' achievements in learning the geometry. Authors interested in diagnosing the difficulties Student Mathematics Education of Kuningan University in the course Geometry 3D through Ability Test of Visual-Spatial Thinking. The purpose of this study is to diagnose visual-spatial thinking abilities Student of Kuningan University and describe efforts to improve student results in the course of the geometry 3D. Based on the exposure of the work about the ability of visual-spatial thinking and discussion it can be concluded that: a) The ability of visual-spatial thinking mathematics education student Kuningan University is still low, especially students who are capable of moderate and low. Students are still experiencing difficulties in resolving problems related to the concept of a perpendicular line and projections; distance of points, lines and areas; as well as the angle between the line and the field; b) The ability of visual-spatial thinking is a skill that must be developed in studying the geometry 3D, one of the low result of learning the geometry 3D is due to the ability of visual-spatial thinking is still low; c) One effort to improve visual-spatial thinking ability of students is learning the geometry of space through problem-based learning with assisted software GeoGebra.Keywords: Visual-Spatial Thinking Ability, Geometri 3D

Proses Berpikir Visual Matematis Siswa Exstrovert Dan Introvert Sekolah Menengah Atas Berdasarkan Tahapan Bulton

“…Menengah Atas ialah persentase Ujian Nasional Berbasis Komputer (UNBK) SMA Tahun Pelajaran 2018/2019 pada bahasan geometri yaitu 36,77%. Hasil persentase tersebut dipengaruhi karena pemahaman siswa pada materi geometri yang masih rendah (Sumarni & Prayitno, 2016). Menurut (Ariawan, 2017) menyatakan bahwa siswa mengalami kesulitan dalam pokok bahasan geometri sehingga diperlukan kemampuan berpikir visual untuk memvisualisasikan agar menjadi gambar, diagram, simbol dan angka sehingga mempermudah siswa dalam memecahkan masalah matematika.…”

Development of Geometry Teaching Materials Assisted Geogebra Android to Improve Mathematical Connection Ability

“…Various technologies, such as dynamic and interactive media, can be used as additional features in teaching material. GeoGebra software is one of the dynamic and interactive technologies that can be used as additional features in teaching material [3], [12] (Sumarni & Prayitno, 2016). GeoGebra can be used to introduce or explain a particular topic in greater depth through the construction process [3].…”

Visual Thinking Ability of Mathematics Education Students on Geometry Transformation Learning Material

“…This shows that when someone faces a problem, they will automatically think about how to solve it. When connected with the senses, there are three ways of thinking, namely auditory thinking (hearing), kinesthetic thinking (feeling) and visual thinking (seeing) (Sumarni & Prayitno, 2016). Of the three ways of thinking, visual thinking can be used as an alternative by students in solving mathematical problems, especially those related to geometry.…”

“…In this study, visual thinking skills are more directed at drawings and graphics as a result of solving geometric transformation problems. This is because visual thinking skills play a role in solving problems that require high-level reasoning, so visual thinking becomes the most important thing in the success of geometry learning for students who are prone to misconceptions if they study without using visual thinking skills (Sumarni & Prayitno, 2016) .…”
