The research method used is a type of design research called validation studies, which consists of three stages: preliminary design, design experiment, and retrospective analysis. The subjects of this study were 27 class X students from SMAN 3 Sungai Penuh. The instruments used are videos to see the learning process and when students work on the given problems, and photos to see the results of student work. The results of the study explored the learning trajectory practiced by using the Ferris wheel as a context, which is seen in students' daily activities. The learning trajectory consists of four activities, namely sketching a simpler Ferris wheel, redrawing the parts of the Ferris wheel where seats A and B are, measuring and comparing sides in a right triangle, and determining trigonometric comparisons.</em></p> 2024-01-24T00:00:00+00:00 Copyright (c) 2024 https://www.journal.ikipsiliwangi.ac.id/index.php/jpmi/article/view/21519 Matematika anak usia dini: Analisis kegiatan berhitung terhadap standar pendidikan matematika NCTM 2023-11-08T13:40:39+00:00 Ririn Hunafa Lestari ririnhunafa@gmail.com Ema Aprianti emaaprianti@ikipsiliwangi.ac.id Hartini Hartini hartini020305@gmail.com <p><em>Many academics and practitioners do research and teaching to develop early childhood numeracy skills by involving various learning elements such as teaching methods and learning media.

So the LKPD developed is an LKPD that is effectively used by students.</em></p> 2024-02-21T00:00:00+00:00 Copyright (c) 2024 https://www.journal.ikipsiliwangi.ac.id/index.php/jpmi/article/view/19159 Studi kasus: Menganalisis kesulitan siswa SMP Negeri 1 Sukanagara pada soal statistika ditinjau dari level kemampuan siswa 2023-11-30T03:30:59+00:00 Kardiansyah Sukma Pawitra kardiansyah.sp@gmail.com Nelly Fitriani nhe.fitriani@gmail.com Eka Senjayawati ekasenjayati@ikipsiliwangi.ac.id <p><em>This study aims to be able to analyze the difficulties of Grade VIII students of SMP Negeri in solving statistical questions. The method used is the case study method. The data used are written tests and interviews. The population and sample in this study were 32 students. The instrument of this study used a questionnaire, namely 6 questions related to statistical questions. Data processing is used by means of written tests and pictures of student answers. The research procedure is the stages of planning, operating, data analysis, and concluding a data. The research will be tested with a number of statistical questions at the application and testing stages, then interviews will be given to several students. The results of the analysis show several criteria based on students' ability to solve statistical problems. Students with high abilities have difficulty in determining the final answer. Students with moderate ability levels experience difficulties in calculating an answer. Students with low ability levels have difficulty understanding the questions given and lack understanding of the material. </em></p> 2024-02-21T00:00:00+00:00 Copyright (c) 2024 JPMI (Jurnal Pembelajaran Matematika Inovatif) https://www.journal.ikipsiliwangi.ac.id/index.php/jpmi/article/view/18635 Penerapan pembelajaran "two stay-two stray" dengan pendekatan kontekstual terhadap pemahaman matematika siswa kelas XII 2024-01-11T03:49:43+00:00 Buyung Fajar Alamsyah buyungf37@gmail.com Wahyu Setiawan kakwahyu3@gmail.com <p><em>This study employs a quasi-experimental approach, utilizing a posttest-only control group design, to investigate the applicability of implementing "two stay-two stray" learning with a contextual approach to enhance the mathematical understanding of class XII students at SMK Negeri 1 Cimahi. The participants in this research consist of class XII students, totaling 34 students each, distributed into control and experimental groups, each subjected to different teaching methods. The research utilized a mathematical understanding ability test as the instrument, with subsequent data analysis carried out using the SPSS Statistics software. The data analysis reveals significant differences in mathematical understanding abilities between students who underwent "two stay-two stray" learning and those who were taught using conventional methods. The t-test yielded an average score of 81.02 with a significance level &gt; 0.05, indicating normal data distribution. </em></p> 2024-02-22T00:00:00+00:00 Copyright (c) 2024 JPMI (Jurnal Pembelajaran Matematika Inovatif) https://www.journal.ikipsiliwangi.ac.id/index.php/jpmi/article/view/20001 Pengembangan LKPD menggunakan pendekatan kontekstual pada materi teorema phytagoras 2023-09-10T00:57:40+00:00 Salsabila Zayyana Royan salsabilazayana354@gmail.com Tatang Supriatna statang776@gmail.com <p><em>This study aims to determine: the process of developing LKPD, the feasibility of the developed LKPD, the effectiveness of the LKPD and the constraints encountered when developing LKPD using the Contextual approach. The method used is research and development which is modified from the R&amp;D research and development model through the 4D stages (Define, Design, Develop, Dessiminate). This research was conducted at Bina Mulia Mandiri Middle School with research subjects in limited trials, namely 15 students and 30 students as subjects in a wide trial. The results showed that the feasibility of teaching materials was categorized as very feasible and practical for use at Bina Mulia Mandiri Middle School based on the results of the validator and student response questionnaires. The obstacles that were encountered during the implementation of the research were that it was difficult for students to change their study habits so far, that is, they just sat watching the teacher explain, students sometimes ignored the instructions from the researcher. </em></p> 2024-01-31T00:00:00+00:00 Copyright (c) 2024 https://www.journal.ikipsiliwangi.ac.id/index.php/jpmi/article/view/21497 Implementasi geogebra pada numbered head together terhadap kemampuan pemecahan masalah matematis dan keaktifan belajar siswa SMP 2023-11-30T02:57:13+00:00 Cahyani Ramadannia ramadannicahyani@gmail.com Anton Nasrullah antonnasrullah1@gmail.com Novi Yendra novi.yendra@binabangsa.ac.id Sri Sukmawati sri.sukmawati@binabangsa.ac.id Silvia Ratnasari silvia@ars.ac.id <p><em>This research investigates the involvement and ability of junior high school students in solving mathematical problems by incorporating GeoGebra in the Numbered Head Together (NHT) approach. A dynamic mathematics application called GeoGebra and (NHT) is thought to offer improved problem solving and active learning. This research used a quasi-experimental with an equivalent control group design for State Middle School students in Cilegon City. Questionnaires and tests of mathematical problem solving abilities are the research instruments used. The analysis techniques used was prerequisite tests (normality test and homogeneity test), hypothesis testing (independent t test) and percentage of learning activity questionnaires. The results of data analysis show statistically significant differences between the control and experimental groups using GeoGebra on NHT learning and student engagement. The research recommendation from the research results is to encourage teachers to integrate dynamic software in the preparation and implementation of teaching using GeoGebra. </em></p> 2024-02-29T00:00:00+00:00 Copyright (c) 2024
