This study aims to develop inquiry based multimedia mathematics teaching materials that can improve the critical thinking skills of high school students in North Sumatera. This research was conducted in North Sumatera Province, from 2016 to 2018. The population of this research is all SMA in North Sumatera Province. The subject of this research is high school students. The sampling technique used purposive random sampling, which is choosing six SMA randomly with three SMA Negeri and three private SMA. To know the influence of mathematics materials based on inquiry of multi media aid developed used quasi experimental research design with control group post test only design. Data collection techniques used questionnaires, observations, and tests. Data were analyzed using descriptive analysis technique, t test and anava. Tests of research found inquiry learning model in groups make students dare to express opinions and accept opinions of others. Multilingual aided instructional learning model interacts with students early mathematical abilities of critical thinking skills. Initial students with moderate and higher category skills prefer to use multimedia-based inquiry learning models, whereas for early low-ability students it is better to use ordinary or expository learning models. Critical thinking ability of students more in the medium category that is equal to 38.71%, this means to improve critical thinking skills in this study need to note one of the 3rd limitation in giving more opportunities for students to think creatively.

Abstract: This study was aimed to develop a set of integrated problem-based mathematics teaching kits implemented with ICT to improve the critical thinking ability of junior high school students. The study used 4-D learning device development model (define, design, develop, disseminate). The data were collected through the observation of the learning process and students' activity, students' questionnaire responses, and a critical thinking ability test. The findings showed that mathematics teaching materials consisting of teaching kits as a teachers’ handbook based on ICT integrated problem-based materials completed with lesson plans, worksheets, and the use of media learning were appropriate to use.Based on the test results conducted in the field, the teaching kits can enhance the students' critical thinking ability. The findings showed that the average gain in two schools was in the range of g 0.7, which means that the students' critical thinking ability belonged to the high category, while that of the third school was in the range of 0.3  g  0.7 at 0.62 which means the students’ critical thinking ability belonged to the fair category. Keywords: learning device, information communication technology (ICT), critical thinking PERANGKAT PEMBELAJARAN MATEMATIKA BERBASIS MASALAH TERINTEGRASI ICT UNTUK MENINGKATKAN KEMAMPUAN BERPIKIR KRITIS SISWA SMP KOTA MEDAN Abstrak: Penelitian ini bertujuan untuk mengembangkan perangkat pembelajaran matematika berbasis masalah terintegrasi dengan ICT untuk meningkatkan kemampuan berpikir kritis siswa SMP. Penelitian menggunakan model pengembangan perangkat pembelajaran model 4-D (define, design, develop, disseminate). Data penelitian diperoleh melalui pengamatan proses pembelajaran dan aktivitas siswa, angket respon siswa, dan tes kemampuan berpikir kritis. Hasil penelitian menunjukkan bahwa perangkat pembelajaran yang terdiri atas bahan ajar matematika sebagai buku pegangan guru berbasis masalah yang terintegrasi dengan ICT disertai RPP, LKS, dan media pembelajaran layak digunakan. Berdasarkan hasil uji coba di lapangan, perangkat pembelajaran tersebut dapat meningkatkan kemampuan berpikir kritis siswa. Hasil penelitian menunjukkan bahwa rata-rata gain pada dua sekolah dimana sekolah pertama dan kedua didapat rentang g 0,7 yang artinya kemampuan berpikir kritis siswa pada kategori tinggi, sedangkan pada sekolah yang ketiga rentang 0,3  g  0,7 yaitu 0,62 yang artinya kemampuan berpikir kritis siswa mengalami peningkatan pada kategori sedang.

Tujuan dari penelitian ini adalah untuk mengetahui apakah ada perbedaan minat belajar siswa dengan media komputer program cyberlink power director dan tanpa media komputer pada pokok bahasan kubus dan balok di kelas VIII SMP Negeri 1 Hamparan Perak tahun ajaran 2009/2010. Populasinya adalah seluruh siswa kelas VIII yang terdiri dari 7 kelas. Penarikan sampel dilakukan dengan cluster random sampling yang artinya setiap kelas memiliki kesempatan yang sama untuk dijadikan sampel penelitian, diperoleh kelas VIII1 sebagai kelas eksperimen dan VIII3 Â sebagai kelas kontrol masing - masing yang berjumlah 30Â siswa. Jenis penelitian ini adalah penelitian eksperimen. Berdasarkan hasil analisis pada kelas eksperimen diperoleh nilai rata â€“ rata pretesÂ 1,989 dan postes 2,879. Sedangkan pada kelas kontrol diperoleh nilai rata â€“ rata pretes 1,985Â dan postes 2,392. Dimana data kedua kelompok berdistribusi normal dan homogen. Pengujian hipotesis dilakukan dengan menggunakan uji t, denganÂ Î± = 0,05. Untuk pretes siswa diperoleh t = 0,05Â sedangkan t1-1/2Î± = 2,018, terlihat bahwa -t1-1/2Î± <t < t1-1/2Î± sehingga Ho diterima yaitu tidak ada perbedan minat belajar siswa antara kelas eksperimen dan kelas kontrol. Pada postes hasil belajar siswa diperoleh t = 5,57 sedangkan t1-1/2Î± = 2,018 dengan t > t1-1/2Î± sehingga Ha diterima yaitu ada perbedan minat belajar siswa denganÂ menggunakan media komputer program Cyberlink Power Director dan tanpa menggunakan media komputerÂ pada pokok bahasan kubus dan balokÂ di kelas VIII SMP Negeri 1 Hamparan Perak tahun ajaran 2009/2010. Dapat disimpulkan bahwa minat belajar kelas eksperimen yang menggunakan media komputer program Cyberlink Power Director lebih tinggi dibandingkan dengan minat belajar pada kelas kontrol yang menggunakan pembelajaran tanpa menggunakan media komputerÂ dengan presentase peningkatan sebesar 20,36 %.Â Kata Kunci : Minat Belajar, Media Komputer program cyberlink power director

The objective of this study is to developing teaching materials of comic form and student worksheets of flat-shape structure material for third grade students of elementary school 060843 with Realistic Mathematics Education. This research is a Research & Development (R & D), Van den Akker models (1999). The samples in this study were 40 third-grade students, for every I and II trials. The result of this study showing that comics, student’s worksheet, and the learning outcomes tests was valid and excellent. The improvement of learning outcomes of students occurred very well. The mean score result on first initial trial test before using the developed teaching materials was 64,25, and then on the final test after using the developed teaching material the mean score was 87,88. On the second trial test, the mean score on the initial test was 64,13, while on the final test the mean score was 88,38. Based on the observation of teacher’s activities, students, teacher’s impressions , student’s responses, and the student’s teaching outcomes that including completeness of objective and classical, then the implementation of comics and student’s worksheet with Realistic Mathematics Education could be declared effective and excellent.

Innovation of teaching to improved the student college’s achievement inthe teaching of Mathematic is explained. The research was aimed to investigate theeffectifity of various, innovated teaching models to improved the student’sachievement in various topic in Mathematic. The study was conduct experimentlyby using innovated teaching with “contextual” and “media”, which are thecompared with conventional teaching method. The result showed the innovation inthe teaching by using media and computer were found very effective and improvingthe ability of the student to understand the concept of mathematic. Studentachievement in the teaching of English Mathematic with the aid of Contextual(X=74,10) was found higher the teaching the same topic by using Conventionalmethod. (X=73,33), where the data analysis has shown that two methods aresignificantly differences. Students achievement with another innovated teachingmethod by using of media for the teaching distillation (X=81,33) was found higherthan that with conventional method, where the data analysis has shown that the twomethods were significantly difference.
