Abstract
One of the external obstacles of students is the learning media used by teachers. Learning achievement will be more developed if students actively participate in learning activities. This study aims to improve mathematics learning achievement at line material. The methodology used in this study is an experimental research methodology. The subjects of this study were 7th class students of SMP Negeri 2 Limpung with class VII A as the experimental group and class VII B as the control group. The results showed that the mathematics learning model assisted by Geogebra at line material is effective to be used, this was seen from the completeness of learning outcomes, the influence of reasoning and communication skills to learning achievement with a regression equation = 36,203 + 0,591x and a coefficient of determination is 68.7%. Mathematical learning strategies by Geogebra are also better than learning mathematics without Geogebra. Thus Geogebra-assisted learning on line material can be used as an alternative method of learning in order to add the variety of teaching methods in an effort to train students' reasoning and communication skills and increase student learning outcomes..

Summary
Salah satu alasan rendahnya minat siswa terhadap matematika karena matematika bersifat abstrak, sehingga perlu perjuangan untuk mempelajarinya. Salah satu materi pada pelajaran Matematika yaitu materi garis-garis sejajar juga bersifat abstrak, sulit untuk dipelajari apalagi kalau menyangkut penalaran dan komunikasi serta pemecahan masalah. SMP Negeri 2 Limpung sebagai salah satu SMP di Kabupaten Batang juga tidak luput dari masalah rendahnya minat siswa terhadap pelajaran matematika. Untuk mengatasi masalah tersebut maka perlu dilakukan inovasi pembelajaran agar siswa lebih tertarik, tidak bosan, dan lebih cepat menangkap materi yang diberikan. Salah satu media pembelajaran yang bisa membantu siswa untuk menvisualisasikan materi garis yang bersifat abstrak adalah media dengan software Geogebra. Apakah pembelajaran matematika berbantuan Geogebra pada materi garis dapat mencapai ketuntasan belajar? 2. Apakah keterampilan penalaran dan komunikasi pada pembelajaran matematika berbantuan Geogebra berpengaruh terhadap peningkatan prestasi belajar siswa? Apakah prestasi belajar kelas dengan pembelajaran matematika dengan bantuan Geogebra lebih baik daripada kelas dengan strategi konvensional?
