This research is included in quasi-experimental research because it has a control group, but it cannot function fully in controlling external variables that affect the implementation of the experiment. The population of this study was all students of class VII of SMP Negeri 5 Yogyakarta in the second semester of 2018/2019 academic year. The sampling technique used is the Random Cluster technique. The results showed that the TPS-assisted comic-learning model was no more effective than the TPS-without comic-learning model in terms of mathematical problem-solving abilities</em></p> Lukman Kalbuadi, Annis Deshinta Ayuningtyas, Sri Adi Widodo Copyright (c) 2020 Journal of Instructional Mathematics https://creativecommons.org/licenses/by-nc/4.0 https://jurnal.stkipkusumanegara.ac.id/index.php/jim/article/view/275 Mon, 16 Nov 2020 00:00:00 +0000 Analisis Kemampuan Representasi Matematis Siswa SMK Ditinjau dari Gaya Belajar https://jurnal.stkipkusumanegara.ac.id/index.php/jim/article/view/364 <p><em>This research aims to describe the mathematical representation abilities of vocational school students in terms of visual, auditory, and kinesthetic learning styles, as well as learning styles that have the best representational abilities in mathematics learning. The research was conducted at SMK Negeri 2 Cilaku Cianjur. The research method used is descriptive research with a quantitative approach. The subjects in this study were all 29 students of class X TKJ 2 with purposive sampling technique. The data used are written tests to reveal mathematical representation abilities, observation and questionnaires to classify students based on learning styles, interviews with students. Data processing used descriptive analysis of the percentage of posttest scores, learning styles by looking at the percentage of observation statements and answers to student questionnaire statements. The results of the data analysis showed that the percentage of achievement of the mathematical representation ability of students with a visual learning style was 71.43% in the sufficient category, students with the auditory learning style 71.25% in the sufficient category, and students with the kinesthetic learning style 73.89% with the sufficient category. The kinesthetic learning style has the best representation ability in mathematics learning with a percentage of 73.89% with a sufficient category.</em></p> Elsa Komala, Asri Maulani Afrida Copyright (c) 2020 Journal of Instructional Mathematics https://creativecommons.org/licenses/by-nc/4.0 https://jurnal.stkipkusumanegara.ac.id/index.php/jim/article/view/364 Mon, 16 Nov 2020 00:00:00 +0000 Bagaimana Mengembangkan Kemampuan Spasial dalam Pembelajaran Matematika di Sekolah?: Suatu Tinjauan Literatur https://jurnal.stkipkusumanegara.ac.id/index.php/jim/article/view/370 <p><em>Spatial ability is an important one of the abilities for completing many tasks in everyday life successfully</em>. <em>Spatial ability is considered a type of different ability to others. Therefore, there needs a study on how are the characteristics of spatial abilities and to develop in schools. This paper is to reveal the ways are developing spatial abilities in learning mathematics. Based on literature review from some research, at least that there are six ways to develop spatial abilities in learning mathematics, namely: </em>(1) <em>using spatial language in daily interactions; </em>(2) <em>teaching for sketching and drawing; </em>(3) <em>using a suitable game; </em>(4) <em>using a tangram; </em>(5) <em>using video games; and </em>(6)<em> origami and folding paper.</em><em> Playing video games like Tetris are exercises for spatial relations, mental rotation, spatial orientation, and spatial visualization</em>.</p> S Sudirman, Fiki Alghadari Copyright (c) 2020 Journal of Instructional Mathematics https://creativecommons.org/licenses/by-nc/4.0 https://jurnal.stkipkusumanegara.ac.id/index.php/jim/article/view/370 Mon, 16 Nov 2020 00:00:00 +0000 Analisis Penerapan Pendidikan Karakter dalam Pembelajaran Matematika di SMP Negeri 1 Simpangkatis Kelas VIII dan MA Muhammadiyah Gantung Kelas X MIA https://jurnal.stkipkusumanegara.ac.id/index.php/jim/article/view/374 <p><em>This study aims to discuss the analysis of the application of character education in mathematics learning at SMP Negeri 1 Simpangkatis class VIII and MA Muhammadiyah Gantung class X MIA. Mathematics learning is used as a medium and a vehicle for character building. By advancing character education in mathematics, Mathematics Learning is no longer to support the development of the cognitive domain but also to develop the affective domain. The research method used a qualitative approach with qualitative descriptive methods. Data collection used observation and interview sheets. The research findings show that character education has been applied in mathematics learning at SMP Negeri 1 Simpangkatis and MA Muhammadiyah Gantung. As for learning activities that can foster character values, including praying together, the teacher giving worksheets and students working in groups, students presenting the results of their work in front of the class. The character referred to is having a strong attitude, discipline, tolerance, solidarity, hard work, responsibility, competitiveness and sportsmanship.</em></p> Intan Juwita, Pendi P, Eka Rachma Kurniasi Copyright (c) 2020 Journal of Instructional Mathematics https://creativecommons.org/licenses/by-nc/4.0 https://jurnal.stkipkusumanegara.ac.id/index.php/jim/article/view/374 Mon, 16 Nov 2020 00:00:00 +0000 Eksperimentasi Model Student Facilitator and Explaining dan Probing-Prompting Ditinjau dari Penalaran Matematis https://jurnal.stkipkusumanegara.ac.id/index.php/jim/article/view/687 <p><em>This research aims are to know: (1) are there differences in learning outcomes between learning models Student Facilitator and Explaining (SFE) and Probing-Prompting (PP)?; (2) whether there are differences in student learning outcomes with high, medium and low reasoning abilities?; and (3) whether there is an interaction effect between learning models and mathematical reasoning on student learning outcomes. This quantitative research is a quasi experiment. The research sample was 80 students in grade 8 at SMP Islam Dewan Da’wah. The sampling technique by cluster random. The research results is: (1) there is no difference in student mathematics learning outcomes between SFE and PP learning models; (2) Student learning outcomes of high mathematical reasoning abilities are better than moderate and low, and student learning outcomes of moderate mathematical reasoning abilities are better than low; (3) not for all student learning outcomes from high, medium and low level of reasoning abilities in SFE learning are better than PP model. In each model, learning outcomes from students’ high level of mathematical reasoning abilities are better than moderate and low, and student learning outcomes from moderate level of mathematical reasoning abilities are better than low.</em></p> Annisa Nur Islami, Nurina Kurniasari Rahmawati, Wahyu Yulianto Copyright (c) 2020 Journal of Instructional Mathematics https://creativecommons.org/licenses/by-nc/4.0 https://jurnal.stkipkusumanegara.ac.id/index.php/jim/article/view/687 Mon, 16 Nov 2020 00:00:00 +0000
