It aims to be open access journal platform which publishes and disseminates the ideas and researches. Its focus is to publish original research (qualitative research, classroom action research, development/design research are top priorities). <strong>JIM</strong> is a scientific Journal that publishes articles of research or review studies in the field of mathematics education. The scope of this journal is: 1) Learning Model and Approach, (2) Curriculum, (3) Assessment and Evaluation, (4) Ethnomathematics, (5) Didactical Design Research, (6) Technology-Assisted Learning.</p> <p style="text-align: justify; margin-top: -60px; margin-left: 15px;">&nbsp;</p> http://jurnal.stkipkusumanegara.ac.id/index.php/jim/article/view/253 Pengaruh Pendekatan Somatis Auditori Visual Intelektual (SAVI) terhadap Peningkatan Kemampuan Koneksi Matematis Siswa SMA 2020-06-05T17:31:32+00:00 Ari Septian ariseptian@unsur.ac.id Citra Laila Ramadhanty jimpendmatstkipkn@gmail.com Puji Rachmawati jimpendmatstkipkn@gmail.com <p><em>The purpose of this study are to find out whether increasing students 'mathematical connection ability with learning using the SAVI approach is better with conventional learning, to find out how students' mathematical connection skills with learning the SAVI approach, and to find out a positive relationship between students 'attitudes towards learning using the SAVI approach with increasing students' mathematical connection abilities. This research method is a quasi experiment that tests the use of SAVI approach to the experimental class and conventional learning in the control class. Sampling using purposive sampling. The selected sample is X MIA 1 as the experimental class and X MIA 4 as the control class. The instrument used was a test instrument for mathematical connection ability and a non-attitude scale questionnaire test. The material in this study was Trigonometry. The results of this study are: (1) improvement of students' mathematical connection ability with the SAVI approach is better than with conventional learning, (2) students' mathematical connection skills with learning with the SAVI approach are good, (3) there is no positive relationship between students 'attitudes towards learning with the SAVI approach with increasing students' mathematical connection abilities.</em></p> 2020-04-29T00:00:00+00:00 Copyright (c) 2020 Journal of Instructional Mathematics http://jurnal.stkipkusumanegara.ac.id/index.php/jim/article/view/263 Pencapaian Kompetensi Geometri Siswa dengan Pembelajaran Kooperatif Tipe Pair Checks dan Teams Games Tournament 2020-06-05T17:43:30+00:00 Restiani R restiani141@gmail.com Ayu Wulandari ayuwulandari@stkipkusumanegara.ac.id Suyanto S lppm@stkipkusumanegara.ac.id <p><em>Students also have not been able to formulate interactions between given elements, questions to be solved, and appropriate mathematical concepts to solve the problem. As a result, the achievement of students' geometry competencies is in the gap towards the goals. Therefore, this study aims to determine the differences in the achievement of geometry competence of students on plane geometry subject between cooperative learning type Teams Games Tournament (TGT) and pair checks. This research was conducted on a sample of 72 people, that is 36 students with TGT type cooperative learning and 36 students with pair checks type learning. Samples were selected by cluster random sampling. This research is a quasi-experimental with posttest only nonequivalent control group design. Quantitative data were obtained using test instruments. Research data were analyzed by parametric statistics. Based on data analysis, it was concluded that there were differences in achievement of students' geometry competencies between TGT type cooperative learning and pair checks on plane geometry subject. Model pair checks is an alternative to learning geometry.</em></p> 2020-04-30T00:00:00+00:00 Copyright (c) 2020 Journal of Instructional Mathematics http://jurnal.stkipkusumanegara.ac.id/index.php/jim/article/view/267 Pembelajaran Penemuan Terbimbing terhadap Kemampuan Generalisasi Matematis Siswa Sekolah Menengah Pertama 2020-06-05T17:41:16+00:00 Yatha Yuni yathayuni@stkipkusumanegara.ac.id Lesna Fisa memei0210@gmail.com <p><em>The purpose of the research for to know the difference mathematical generalization ability of student are taught by use guided discovery learning and expository. The research was held at SMPN 21 Bekasi in second semester academic year 2016-2017. The sample&nbsp; is class VII.2 and VII.5 (76 students). This research used quasi-experimental with statistic group comparison or post-test-only with nonequivalent groups design. Instrument be used is an essay test to measure mathematical reflective thinking ability. Before tested instrument analyzed by correlation product moment to test the validity, reliability by formula alpha cronbach and an index of the lurch. The data is analyzed firstly be done test regulation is test normality with Lilliefors and also test homogeneity by using Fisher. The result of normality test of class experiment and control can be conclude that both of the sample are from normal distribution. While the result of homogeneity test can be conclude the population of both have a homogeneity variance. The result of research were obtained t result is 5,29 with significance ? is 0,05. The result of research showed a difference mathematical generalization ability of student through guided discovery learning and expository.</em></p> 2020-04-30T00:00:00+00:00 Copyright (c) 2020 Journal of Instructional Mathematics http://jurnal.stkipkusumanegara.ac.id/index.php/jim/article/view/264 Pencapaian Kemampuan Low Order Thinking Siswa antara Pembelajaran Probing Prompting dan Matematika Realistik 2020-06-05T17:38:24+00:00 Dumaria Theresia dumariasianturi1@gmail.com Mohammad Syafi’i mohamads@stkipkusumanegara.ac.id Niken Vioreza niken@stkipkusumanegara.ac.id <p><em>Not infrequently when students are dealing with mathematics problems where they do not know what they are supposed to do. Learning in class can make a habituation to students. This study aims to determine whether or not there are differences in achievement of students' Low Order Thinking (LOT) abilities between learning Probing Prompting (PP) and Realistic Mathematics (MR) on quadrilateral. This research was conducted with a total sample of 60 students, namely 30 students in class VIIA with PPL learning and 30 students in class VIIB with MR learning. The sample selection is done by cluster random sampling. The instruments used to collect data are based on three dimensions in the cognitive domain, namely remembering, understanding, and applying. The results of the descriptive statistical analysis of the data show that the average achievement of students in the PP learning group is equal to 75.36, while the average achievement of students in the MR group is equal to 68.53. Based on the results of data analysis, it was concluded that there were significant differences in the LOT achievement of students between PP and MR learning on Quadrilateral material.</em></p> 2020-04-30T00:00:00+00:00 Copyright (c) 2020 Journal of Instructional Mathematics http://jurnal.stkipkusumanegara.ac.id/index.php/jim/article/view/265 Kemampuan Pemahaman Matematis Siswa dengan Menggunakan Cabri 3D 2020-06-05T17:45:17+00:00 Bayu Jaya Tama bayujaya88@gmail.com Sri Rezeki srirezeki104@gmail.com Rezkiyana Hikmah rezkiyana.hikmah2706@gmail.com <p><em>The purpose of this study was to determine differences in students' mathematical understanding abilities between those using Cabri 3D by using ordinary learning models. This research is a quasi-experimental research. The sample of the research was grade VIII students of one junior high school in Cibinong. The research instrument used was pretest and posttest. Research data were analyzed using t-test. The results of this study indicate that the mathematical understanding ability of students who learn with 3D cabri media is better than students who study with ordinary learning.</em></p> 2020-04-30T00:00:00+00:00 Copyright (c) 2020 Journal of Instructional Mathematics
