<![CDATA[Penelitian ini bertujuan untuk mengetahui besarnya peningkatan keaktifan dan prestasi belajar matematika pada materi geometri menggunakan software geogebra. Penelitian ini dilaksanakan di kelas IX SMP Negeri 2 Tanjung Morawa yang berjumlah 210 siswa. Metode yang digunakan adalah metode penilitian tindakan kelas yang terdiri dari dua siklus, analisis yang digunakan adalah deskriptif komparatif dengan membandingkan data antar siklus. Adapun indikator kemampuan matematis siswa dilihat dari hasil belajar nya, apakah terdapat perubahan kemampuan matematis siswa sebelum dan sesudah menggunakan software Geogebra dalam pembelajaran geometri. Geogebra digunakan untuk memvisualisasikan obyek geometri yang akan ditransformasikan. Melalui proses visualisasi siswa mencoba, menalar, dan akhirnya dapat menemukan konsep transformasi. Hasil penelitian menunjukkan adanya peningkatan keaktifan siswa selama pembelajaran. Hasil tes setiap siklus menunjukkan adanya kenaikan jumlah siswa yang mencapai ketuntasan minimal (KKM). Pada kondisi akhir siklus siswa yang tuntas dalam belajar mencapai 85,24%. Berdasarkan hal ini maka pembelajaran dengan menggunakan software geogebra dapat meningkatkan kemampuan matematis.]]>

<![CDATA[The purpose of this study is to describe the differences in the effectiveness of creative problem solving learning models and conventional learning models in terms of reasoning, communication, and self-esteem abilities. This research is a quasi-experimental research with a non-equivalent comparison group design. The research subjects were students at SMP Negeri 2 Tanjung Morawa. The sample consisted of 50 students from two class VII, each of which followed the conventional learning model and creative problem solving learning model. The research instrument consisted of a test of students' reasoning abilities and a test of students' mathematical communication skills. The analysis technique uses descriptive analysis and Hotteling's Trace. The results of the study at the 5% significance level showed that: (1) the creative problem solving learning model was effective in terms of students' mathematical reasoning and communication abilities; (2) the conventional learning model is effective in terms of students' mathematical reasoning and communication abilities; and (3) there is a difference in effectiveness between creative problem solving and conventional learning models in terms of students' mathematical reasoning and communication abilities.]]>

<![CDATA[Mathematics learning does not only focus on improving numeracy skills, because in reality numeracy skills are not enough to face everyday life problems. The demands on students' abilities to master mathematics include the ability to use numbers, mathematical symbols and arithmetic operation skills. This ability is related to numeracy literacy. This research aims to improve numeracy literacy skills in mathematics subjects with the Indonesian Realistic Mathematics Education Approach (PMRI) in class X students at Nur Azizi Private Vocational School, Tanjung Morawa. This research used a qualitative approach with a classroom action research design. The research was carried out in 3 cycles and involved 30 class X students. Data was obtained using observation, written tests and interviews. The results of the research show that the PMRI approach can improve numeracy literacy skills in mathematics subjects in class 47.58% in the inappropriate category, cycle II 63.45% in the inappropriate category, and cycle III 82.15% in the appropriate category. In teaching and learning activities, teachers are expected to use this method as an alternative in mathematics and other subjects to increase students' numeracy literacy activities and abilities and it is hoped that this research can be used as a reference for other researchers.]]>
