Geometri Dan Permasalahan Dalam Pembelajarannya (Suatu Penelitian Meta Analisis)

Abstract

Geometry teaches us not only about how to give appreciation for something, but also how to find connections that occur between geometry material and other lecture material. In addition, geometry also trains communication through exploration, discussion, conjecture and investigation. The problems that exist in basic geometry skills in a row are problems related to logic skills, drawing skills, visual skills, verbal skills, and applied skills. Based on geometric learning using analytical presentation, the problem of using axiomatic deductive is at the top, then the problem of perception. Misconceptions about visual processes and activities, and finally problems with the use of procedures, concepts, and principles

Keterampilan Komunikasi Matematis Siswa Pada Materi Bangun Ruang Sisi Datar Ditinjau Dari Self Efficacy

“…Geometri merupakan salah satu materi yang berkaitan dengan komunikasi matematis. Sebagaimana yang disebutkan oleh Budiarto & Artiono (2019) bahwa geometri melatih keterampilan komunikasi matematis siswa melalui konjektur, diskusi, eksplorasi dan investigasi. Geometri memperoleh bagian terbesar dalam pembelajaran matematika dibandingkan materi lainnya, yaitu 41% (Supriadi, 2015).…”

Exploration of Students’ Understanding of Geometry Concepts

“…At the analysis level, which is the highest level, it focuses on mathematicising the situation, conducting analysis and interpretation, developing models and strategies, as well as developing mathematical models and generalizing. According to Budiarto & Artiono (2019) that at this level mediation learning is very suitable for a learning activity to recognize, assemble, and construct existing information. As revealed by Rahman & Yunita (2018) in their research which explains that the PACE learning model (Project, Activity, Cooperative Learning, and Exercise) can improve students' ability to prove geometry.…”

Literasi Spasial Siswa SMP Dalam Menyelesaikan Soal Geometri Ditinjau Dari Perbedaan Gaya Belajar

“…Selain itu siswa mengalami kesulitan dalam menguasi materi geometri yang erat kaitannya dengan literasi spasial yang dapat dilihat dari persentase penguasaan materi Ujian Nasional siswa SMP sebesar 47,19% (2015/2016), 48,57% (2016/2017), 41,40%(2017/2018) Adapun beberapa penelitian yang menunjukkan kesulitan siswa dalam geometri antara lain lemahnya konsep-konsep geometri, kesulitan dalam memecahkan masalah geometri, dan rendahnya dalam penalaran siswa dalam objek-objek geometri. (Budiarto & Artiono, 2019;Subaidah,et.al. 2017).…”
