<![CDATA[Penelitian ini bertujuan untuk mengetahui: (1) peningkatan kemampuan komunikasi dan disposisi matematis siswa yang memperoleh pembelajaran kooperatif tipe jigsaw dan pembelajaran konvensional, (2) interaksi antara pembelajaran dan kemampuan awal siswa terhadap kemampuan komunikasi dan disposisi matematis siswa. Penelitian ini dilaksanakan di SMP Muhammadiyah kota Padangsisimpuan. Jenis penelitian yang digunakan adalah kuasi eksperimen dengan pre-test-post-test control group design. Populasi dalam penelitian ini terdiri dari seluruh siswa kelas VII SMP Muhammadiyah Kota Padangsidimpuan, sedangkan sampelnya terdiri 30 siswa pada kelas VII-1 sebagai kelas eksperimen dan 30 siswa pada kelas VII-3 sebagai kelas kontrol. Pengambilan sampel dilakukan melalui teknik purpose sampling. Instrumen penelitian yang digunakan adalah tes kemampuan komunikasi matematis siswa, angket disposisi matematis siswa. Pengujian hipotesis statistik dalam penelitian ini menggunakan uji ANAVA dua jalur. Hasil penelitian menunjukkan bahwa (1) peningkatan kemampuan komunikasi dan disposisi matematis siswa yang memperoleh pembelajaran kooperatif tipe jigsaw lebih tinggi daripada pembelajaran konvensional. Hasil rerata peningkatan kemampuan komunikasi matematis siswa yang diberi pembelajaran kooperatif tipe jigsaw dan pembelajaran konvensional masing-masing sebesar 0,64 dan 0,65, dan rerata peningkatan disposisi matematis siswa masing-masing sebesar 0,43 dan 0,45. (2) terdapat interaksi antara pembelajaran dan kemampuan awal matematika siswa terhadap kemampuan komunikasi dan disposisi matematis siswa]]>

<![CDATA[Paradigma terhadap sulitnya belajar matematika seolah menjadi kelaziman bagi siswa dalam pelaksanaan proses belajar mengajar di kelas. Kreativitas guru dalam melaksanakan pembelajaran dikelas sangat menentukan terhadap pencapaian keberhasilan siswa dalam menerima materi yang diajarkan. Sebagai guru yang kreatif tentunya harus memiliki skill di bidangnya agar siswa yang diajarkan berhasil guna dalam proses pembelajarannya. Pemanfaatan media pembelajaran dalam matematika tentunya menjadi sebuah kreativitas yang harus dimiliki oleh guru matematika sebab dengan penguasaan dan penggunaan media tersebut diharapkan siswa merasa ikut memiliki pelajaran yang disampaikan oleh guru. Saat ini, program computer dalam pembelajaran matematika merupakan keniscayaan. Salah satu program computer yang dapat dimanfaatkan dalam pembelajaran matematika adalah GeoGebra. GeoGebra adalah program dinamis yang dengan beragam fasilitasnya dapat dimanfaatkan sebagi media pembelajaran matematika untuk mendemonstrasikan atau memvisualisasikan konsep – konsp matematika serta sebagi alat bantu untuk mengkonstruksi konsep – konsep matemtika. Namun, tidak semua guru matematika mampu dan cakap dalam memanfaatkan media pembelajaran GeoGebra. GeoGebra merupakan aplikasi yang mudah untuk dipahami oleh siswa dan dapat digunakan hampir untuk semua materi yang ada dalam matematika sehingga dengan menggunakan aplikasi ini siswa tidak merasa monoton dalam proses belajar mengajar di kelas. Anggapan siswa tehadap matematika yang sulit akan hilang seiring dengan skill yang akan mereka miliki dengan pemanfaatan GeoGebra ini. Artikel ini menyajikan uraian bagaimana pengabdi menerapkan GeoGebra dalam setiap pembelaran matematika.Target kegiatan ini adalah guru-guru matematika di Tapanuli Selatan. Jumlah peserta workshop sebanyak 16 orang. Tempat pelaksanaan kegiatan dilaksanakan di SMA Negeri 1 Sipirok. Metode pelaksanaan yang digunakan adalah metode eksperimental dan pendampingan. Dengan adanya kegiatan ini diharapkan mampu memberi informasi dan pengetahuan bagaimana memanfaatkan media pembelajaran matematika sehingga menjadi sebuah pelajaran yang menyenangkan bagi guru dalam membelajarkannya.Kata Kunci : GeoGebra, Matematika]]>

<![CDATA[AbstractThis study aims to determine: the influence of students' mathematical critical thinking analysis in solving mathematical problems through the reward and punishment method in SMA Negeri 1 Batang Angkola. The type of research used is quasi-experiment with pre-test-post-test control group design. The population in this study consisted of all class X students of SMA Negeri 1 Batang Angkola, while the sample consisted of 20 students in class X-1 as an experimental class and 20 students in class X-2 as a control class. Sampling is done through purpose sampling technique. The research instrument used was a test of students' mathematical critical thinking skills. Statistical hypothesis testing in this study used the t test. The effect of the ability of mathematical critical thinking students who get learning with reward and punishment learning is higher than students who get regular learning. With the results of the calculation obtained, then t count = 1.85 and at the level of α = 0.05 and dk = 20 + 20 - 2 = 38 then obtained t table = 1.54. Thus it is concluded that tcount> t table or 1.85> 1.54, so Ha is accepted and H0 is rejected. This shows that students' critical mathematical thinking is good enough. With reward and punishment learning makes students more active, enthusiastic and independent. This means that the influence of critical thinking in mathematics mathematics learning of students towards reward and punishment learning is better than students' critical thinking of mathematics by using ordinary learning in class X of SMA Negeri 1 Batang Angkola.
