Abstract

This study aims to describe the mathematical representation abilities of eleventh-grade students in solving matrix problems. A qualitative approach with a case study design was employed. The research participants consisted of six students selected from a total of 29 students in Class XI MIPA 4 at SMAS Mujahidin Pontianak. Participants were chosen through purposive sampling based on three levels of mathematical ability (high, moderate, and low) with two students representing each category. The study analyzed students' representation abilities across three dimensions, namely visual, symbolic, and verbal. Data were collected through written tests and interviews. The data analysis process involved three stages: data condensation, data display, and conclusion drawing. The results revealed that students with high ability demonstrated comprehensive mastery of all three forms of representation. Students with moderate ability showed sufficient proficiency in visual and symbolic representation but had limitations in verbal representation. Meanwhile, students with low ability encountered difficulties in all three aspects. These findings suggest that teachers should design instructional strategies and tasks that promote students' abilities to make conjectures, interpret, justify, and connect mathematical ideas, thereby enhancing students' mathematical representation abilities.

Abstract

This study aims to evaluate the quality of quiz questions for student-level students, organized by the Mathematics Education Study Program, FTIK IAIN Pontianak together with the Mathematics Education Student Association. The evaluation was carried out based on aspects of material, construction, language, and Bloom's Taxonomy. The mathematics materials presented in the competition include Algebra, Geometry, Number Theory, Trigonometry. Data were taken from documents of questions, answers, and participant scores. The analysis showed that the majority of questions were of good quality, although some aspects, such as the balance of cognitive levels in Bloom's Taxonomy, needed improvement. This study is expected to be the basis for the development of similar competitions in the future

Abstract

This research aims to produce LKPD based on Problem-Based Learning (PBL) for junior high school mathematics. This development research adopts the ADDIE development model with stages including Analysis, Design, Development, Implementation, and Evaluation. The quality of the LKPD is reviewed from the assessment of material experts, media experts, and student responses. The research instruments used were a material expert questionnaire, a media expert questionnaire, and a student response questionnaire. The LKPD was tested in class VII MTS Mujahidin with 32 students as subjects. The LKPD developed contains learning activities according to PBL steps, presents problems related to daily life at the beginning of learning, and can be used in learning. Judging from the material aspect, the LKPD is assessed as good with an average assessment score by material experts of 4.00. Judging from the media aspect, the LKPD is considered good with an assessment score by media experts of 3.60. Students' responses to the use of LKPD are included in the good category with an average assessment score of 4.05. It can be concluded that the PBL-based LKPD for class VII junior high school is suitable for use in implementing mathematics learning.   Keywords: Development, , Problem Based Learning, Student Worksheets

Abstract

Tujuan dari penelitian ini adalah banyaknya mahasiswa yang kesulitan dalam menyelesaikan masalah trigonometri. Penelitian ini bertujuan untuk mendiskripsikan kesulitan mahasiswa dalam menyelesaikan masalah trigonometri khususnya pembuktian identitas trigonometri ditinjau dari kemampuan berpikir kritis tinggi, sedang, dan rendah serta faktor-faktor yang mempengaruhi kesulitan mahasiswa. Penelitian ini merupakan penelitian deskriptif kualitatif. Subjek pada penelitian ini adalah 16 mahasiswa prodi Tadris Matematika IAIN Pontianak, yaitu 3 mahasiswa dengan kemampuan berpikir kritis tinggi, 8 mahasiswa dengan kemampuan berpikir kritis sedang, dan 5 mahasiswa dengan kemampuan berpikir kritis rendah. Teknik pengumpulan data pada penelitian ini menggunakan tes tertulis dan wawancara. Teknik analisis data dilakukan dengan 3 tahapan yaitu reduksi data, penyajian data, dan penarikan kesimpulan. Teknik pemeriksaan keabsahan data menggunakan triangulasi sumber yang membandingkan hasil tes tertulis satu sumber dengan sumber lainnya dalam kategori yang sama dan kemudian digali lebih dalam melalui wawancara. Hasil penelitian menunjukkan bahwa mahasiswa dengan kemampuan berpikir kritis tinggi tidak mengalami kesulitan. Mahasiswa dengan kemampuan berpikir kritis sedang mengalami kesulitan dalam menerapkan konsep. Sedangkan mahasiswa dengan kemampuan berpikir kritis rendah mengalami kesulitan dalam menerapkan konsep, kesulitan dalam menerapkan prinsip, dan kesulitan dalam menyelesaikan masalah verbal.

Abstract

Mathematics is taught from elementary school onwards. However, not all students are able to follow this learning well, but many students cannot complete and master the mathematical concepts being taught, which means their learning outcomes are still below the KKM. The study focuses on the teacher's efforts to improve mathematics learning outcomes when the teacher does not complete the task completely, namely. H. learning is still teacher-centered. The purpose of this study was to improve student learning outcomes in learning mathematics in Fractions material by using concrete object props. The subjects of this study were teachers and students of SDN 2 Buyut Udik, Gunung Sugih District, Central Lampung Regency. The problems of this study are: low learning outcomes in mathematics from fractional material, teacher learning abilities must be improved again, teachers do not use the learning environment, learning is still teacher-centered resulting in low student scores. The type of research used is Classroom Action Research (CAR). The data collection technique was carried out by posttest. The results showed that 10 students (45%) of the 22 students achieved the KKM before using the Betoniobjekti teaching tool. After using concrete object visual aids in Cycle I the number of students who achieved the KKM increased to 17 students (77%), which was then continued in Cycle II with the results of students who achieved the KKM to 20 students (91 students).
