Teacher and students response to learning devices based on van hiele theory

Abstract

Critical thinking is one of the higher order thinking ability that needs to be developed in the 21st century. In fact, that the students’ critical thinking ability are still low. In learning geometry students are still dependent on the teacher in receiving information, the media are inadequate in learning geometry so that students have not been trained to solve geometry problems with critical thinking. Thus a geometrical learning devices was made based on the van hiele theory. Before using the geometry learning devices, it is validated first with the experts, asking the teacher’s response, and student responses through questionnaires and interviews. The subjects of this study were class VIII students of SMP 13 Padang. The results showed that the response of teachers and students showed the geometry learning devices is practical criteria.

The Effect of Van Hiele Learning Model Based Geogebra on Students’ Spatial Ability

“…Geometry is one of the main concepts students learn, and a branch of mathematics taught before higher education and then has an essential role in mathematics [1], [2]. The explanation for this is that students already know geometric ideas as previously.…”

“…The difficulty of understanding geometry occurs because they have a problem thinking of abstract forms, analyzing the properties of observed geometric objects, and presenting geometric objects in images. Moreover, students also feel less interested in learning mathematics [1]- [3]. The previous observation [5] stated that the three-dimensional figure is the most challenging mathematics learning material.…”

Profil Kemampuan Berpikir Geometri Van Hiele Siswa Pada Level 1 Dan Level 2

“…Selain itu, siswa juga merasa kurang tertarik untuk belajar matematika. Sehingga pemahaman siswa tentang geometri masih rendah dan perlu ditingkatkan untuk memecahkan masalah (Wiska, Musdi, & Yerizon, 2020). Hal ini sejalan dengan Widiyaningsih, Zaenuri, Dwijanto (2020) bahwa pembelajaran geometri membutuhkan kemampuan abstraksi yang relatif tinggi, meskipun tingkat berpikir geometri antar siswa berbeda-beda.…”
