Origami and GeoGebra Activities Contribute to Geometric Thinking in Second Graders

Abstract

This article describes the beneficial effects of an intervention program, based on the computerized Origametria program and the GeoGebra environment, for acquiring geometric concepts in the second grade. Eighty-eight second-graders, from both Hebrew-speaking and Arabic-speaking schools, were instructed in groups by eighteen Hebrew and Arabic-speaking college students, respectively. The groups met for twenty-three 45-minute sessions throughout the schoolyear, undergoing different activities in Origametria and GeoGebra about the concepts of triangle, quadrilateral, square, rectangle, right angle and reflectional symmetry. The pupils' geometric knowledge was compared pre and post intervention to that of twenty-nine pupils in the control group. Pre-intervention, the experimental group's geometric knowledge was significantly lower than that of the control group and there were differences in knowledge between pupils from the Hebrew-speaking and Arabic-speaking school. Post-intervention, a considerable improvement was noted in the experimental group, to the point that group differences were no longer significant. Differences between Hebrew and Arabic-speakers in knowledge of most concepts were also eliminated. Due to the intervention program, the knowledge gap between low and high achieving pupils in the pre-intervention test was closed. Thus, all pupils were brought to a similar level of geometric knowledge. There were no gender differences pre or post-intervention.

Measuring Spatial Ability and Geometric Thinking Level of Prospective Elementary School Teachers Using the Rasch Model

“…In addition, the use of multimedia can affect spatial abilities (Heo & Toomey, 2019). Some of the media that are often used in learning geometry are tangram (Bergstrom & Zhang, 2016;Moursund, 2007), geoboard (Mudaly & Sibiya, 2018;Trimurtini, Safitri, Sari, & Nugraheni, 2020), android-based media (Bektiningsih, Nugraheni, & Sari, 2020), geogebra (Başara, 2020;Klemer & Rapoport, 2020;Topuz & Birgin, 2020) electronic module (Suastika & Wahyuningtyas, 2020), augmented (İbili, Çat, Resnyansky, Şahin, & Billinghurst, 2019) and virtual reality-based media (Gecu-parmaksiz & Delialioglu, 2019).…”

Analisis Kemampuan Literasi Matematik Melalui Think-Talk-Write (Ttw) Berbantuan Geogebra Ditinjau Dari Self Efficacy Peserta Didik Kelas VI

“…Untuk mengatur proses pembelajaran di kelas, guru harus memberikan arahan yang jelas kepada peserta didik dalam melaksanakan kegiatan-kegiatan pada model pembelajaran TTW. Geogebra adalah software dinamis untuk pembelajaran matematika yang lebih efektif, efisien, dan menyenangkan bagi guru dan peserta didik, serta memiliki fitur 2D dan 3D (Klemer, 2020). Dengan menggunakan Geogebra, materi yang disajikan dapat disampaikan dengan baik, karena dengan adanya gambar visualisasi yang dinamis dapat menarik perhatian peserta didik dalam pembelajaran lingkaran.…”

GeoGebra-based flipped learning model: An alternative panacea to improve student’s learning independency in online mathematics learning

“…Furthermore, this software is user-friendly. So, it does http://journals.ums.ac.id/index.php/jramathedu not require particular computer expertise (Hohenwarter et al, 2009;Klemer & Rapoport, 2020). Previous studies show that implementing GeoGebra can increase students' analytical ability and activeness in learning mathematics (Hermuttaqien et al, 2019;Kholid et al, 2022;Kllogjeri, 2010;Kristanto et al, 2016a;Septian et al, 2019;Yamin et al, 2020).…”
