<![CDATA[The material for the polyhedron is a primary subject for mathematics that students must learn at the semester VIII junior high school level. However, the reality in the field is that studying the material is still considered difficult by students. Many students have some problems in solving the Higher Order Thinking Skill (HOTS) questions of the material. This research was conducted to examine the factors that cause student errors in answering the HOTS questions on the polyhedron. The method used in this research is descriptive qualitative with research subjects is the IX grade students of SMP Negeri 02 Cipongkor, with a sample from IX-F students, 11 boys, and 17 girls. The data analysis technique used in this research is to analyze the factors that cause student errors in solving the test questions of the data sharing materials and then calculate the percentage score for each question and interpretation based on Arikunto understanding criteria. Based on the results of the study, it was found that the factors that caused student errors in solving the problem were: 1) Students had difficulty in solving problems at the re-examination stage because students could not prove the truth of the answers they had obtained; 2) lack of accuracy in interpreting problems and writing formulas; 3) lack of understanding of prerequisite material; 4) difficulty in determining the length of the cube and cuboid edges; 5) difficulty in calculating the volume and surface area of a trapezoidal prism.]]>

<![CDATA[Calculus is one of the basic subjects that must be mastered by every student of the mathematics education study program, if students cannot understand other mathematics-related courses, students will experience difficulties and will hinder their professionals from becoming good teachers. Because, a teacher must be able to convey information that is important for mathematics to be applied to daily life to students, this encourages students to be motivated to develop mathematics in the future related to technology. In current developments, teachers are trying to make mathematics learning strategies by using teaching aids to improve students 'reasoning abilities, so that students can provide based on students' experiences when doing it, but the biggest obstacle by teachers is the cost that is too large and the time is too long. And as a consideration, making ICT-based media is more effective in overcoming these two factors by developing Javascript geometry.]]>

<![CDATA[Pembelajaran matematika di setiap tingkat pendidikan lebih berorientasi pada peningkatan kecerdasan siswa dibanding perkembangan kreativitas siswa. Bagi siswa terkadang hasil belajar lebih penting dibandingkan proses saat mereka belajar. Sehingga, siswa lebih mementingkan nilai daripada ilmu yang mereka dapatkan. Dalam pembelajaran matematika di MTs Negeri Sukasari Cimahi, mengenai materi SPLDV, siswa kelas VIII G merasa kesulitan dalam: 1) memahami informasi pada soal cerita SPLDV, dan 2) mengingat dan mengaplikasikan metode-metode penyelesain pada soal SPLDV. Pendekatan open-ended digunakan sebagai salah satu strategi pembelajaran agar terjadi peningkatan pada kemampuan berpikir kreatif matematis siswa. Penelitian ini dilakukan dengan 2 siklus dengan setiap siklus terdiri dari 2 pertemuan. Sebelum dimulai tindakan dilakukan tes awal kepada siswa, kemudian dilanjutkan dengan kegiatan siklus I dan siklus II yang menggunakan pendekatan open-ended. Hasil penelitian ini menunjukkan adanya peningkatan kemampuan berpikir kreatif matematis siswa terlihat dari ketuntasan hasil belajar siswa yaitu pada hasil tes awal tidak ada siswa yang nilainya melebihi KKM, pada siklus I terjadi peningkatan sebesar 30,6%, pada siklus II terjadi peningkatan sebesar 47,2%. Hal ini menunjukkan bahwa kemampuan berpikir kreatif matematis siswa kelas VIII MTs Negeri Sukasari Cimahi dapat ditingkatkan melalui pendekatan open-ended.]]>
