Abstract

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.

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  sebagai kelas kontrol masing - masing yang berjumlah 30  siswa. Jenis penelitian ini adalah penelitian eksperimen. Berdasarkan hasil analisis pada kelas eksperimen diperoleh nilai rata – rata pretes  1,989 dan postes 2,879. Sedangkan pada kelas kontrol diperoleh nilai rata – rata pretes 1,985  dan postes 2,392. Dimana data kedua kelompok berdistribusi normal dan homogen. Pengujian hipotesis dilakukan dengan menggunakan uji t, dengan  α = 0,05. Untuk pretes siswa diperoleh t = 0,05  sedangkan t1-1/2α = 2,018, terlihat bahwa -t1-1/2α <t < t1-1/2α 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 t1-1/2α = 2,018 dengan t > t1-1/2α sehingga Ha diterima yaitu ada perbedan minat belajar siswa dengan  menggunakan media komputer program Cyberlink Power Director dan tanpa menggunakan media komputer  pada pokok bahasan kubus dan balok  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 komputer  dengan presentase peningkatan sebesar 20,36 %. Kata Kunci : Minat Belajar, Media Komputer program cyberlink power director

Abstract

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.

Abstract

This study aims to determine whether there is a positive and significant effect of the Group Investigation type cooperative learning model on students' mathematical reasoning and communication skills in the Pythagorean Theorem sub-subject in class VIII SMP Negeri 1 Munte in the 2019/2020 Academic Year. The population in this study were all class VIII students of SMP Negeri 1Munte for the 2019/2020 Academic Year. While the sample in this study consisted of 2 classes of 38 students each in class VIII-1 as the experimental class and class VIII-3 as the control class. The experimental class uses the Group Investigation cooperative learning model consisting of 5 students per group, and the control class uses the Group Investigation type cooperative learning model consisting of 2 students per group. This type of research is an experiment. Prior to testing the hypothesis, the normality and homogeneity tests are tested first. Normality was tested using the Lilliefors technique and homogeneity using the F test. From the tests performed, it was found that both samples were normally distributed and homogeneous. There is a positive and significant influence of the Group Investigation cooperative learning model on the mathematical reasoning abilities of junior high school students. There is a positive and significant influence of the Group Investigation type of cooperative learning model on the mathematical communication skills of junior high school students because the average communication ability of students who are taught with the Group Investigation type cooperative learning model consisting of 5 people per group is higher than the average communication ability of students who are taught with the Group Investigation type cooperative learning model consisting of 2 people per group

Abstract

The subjects of this qualitative descriptive research were class VIII students of SMP Negeri 4 Tarutung located in North Tapanuli Regency. The aim of this research is to determine and explain students' mathematical communication abilities when solving problems using Bruner's Theory. The data is in the form of written test results given to students to assess their mathematical communication skills in solving problems using Bruner's Theory. The results of the interview also consist of students' answers to verbal questions given to obtain additional information. Documentation data in the form of pictures and archives of test answers taken by class VIII students of SMP Negeri 4 Tarutung. Data collection methods include written tests, interviews, and documentation. Data analysis is carried out by reducing data, presenting and drawing conclusions. The results of the research show that students' mathematical communication skills when solving problems use Bruner's Theory 43% of students with high mathematical communication skills were able to solve questions correctly and well, while 36% of students with moderate abilities could only meet some indicators, and 21% of students with low abilities could not meet all the indicators.
