Partisipan penelitian ini berjumlah 32 orang yang sedang kuliah Geometri Analitik tahun ajaran 2017/2018 di Departemen Pendidikan Matematika Fakultas Pendidikan Matematika dan Ilmu Pengetahuan Alam di salah satu universitas di Indonesia. Sehingga untuk mengetahui kesalahan mahasiswa tersebut, peneliti melakukan studi eksploratif dengan memberikan tes tertulis individu (dua soal uraian) pada konsep titik dan garis pada bidang dalam perkuliahan geometri analitik. Namun, kenyataannya banyak mahasiswa yang melakukan kesalahan dalam menyelesaikan soal-soal geometri. Geometri merupakan bagian dari matematika yang penting bagi siswa dari tingkat dasar sampai universitas. It was also determined that the CSCL environment with GeoGebra software significantly increased students’ attitudes toward geometry. It was indicated in this study that CSCL using GeoGebra software significantly increased seventh grade students’ geometry achievement and retention of learning in comparison to textbook-based direct instruction. Data were analyzed through SPSS 17.0 statistical software by using a t-test and ANCOVA test. A retention test was applied to both groups eight weeks after the post-test. The Geometry Achievement Test (GAT) and Geometry Attitude Scale (GAS) were applied to groups as pretest and post-test. CSCL activities using GeoGebra software were implemented in the experimental group, while instruction in the control group continued with textbook-based direct instruction.
This study was carried out with 62 seventh grade students in a city in western Turkey. The study was designed using a quasi-experimental research method with pretest, post-test and delayed post-test.
The purpose of this study was to examine the effects of using GeoGebra software in a computer-supported collaborative learning (CSCL) environment on seventh grade students’ geometry achievement, retention of learning, and attitudes toward geometry.
