Abstract

This study is based on the importance of applied, contextual, and relevant mathematics learning that meets the needs of the workplace and entrepreneurship. This study aims to develop a mathematics learning design for compound probability events by applying a Problem-Based Learning (PBL) model contextualized with volleyball. This study employs a design research method consisting of three stages: preliminary design, teaching experiment, and retrospective analysis, conducted at SMKN 1 Rengasdengklok, involving two classes: a small class with 12 students and a large class with 35 students from class X TJKT 1. Data was collected by recording classroom activities and group work, collecting students' work, administering achievement tests, and interviewing them. This study demonstrates that volleyball as a contextual medium fosters improved conceptual understanding of compound probability among vocational high school students. The retrospective analysis of the learning process showed that through activities linking probability to volleyball games, students developed understanding through experiences such as calculating the probability of a successful serve or the ball entering or exiting the court, facilitated through Student Worksheets with a volleyball context. Based on this research, it is recommended that the Realistic Mathematics Education (RME) approach with a volleyball context be applied in probability learning at vocational high schools.

Abstract

Selama ini matematika dipandang sebagai matapelajaran yang membosankan dan sulit. Para guru telah melakukan berbagai cara untuk menghapuskan pandangan tersebut. Salah satu cara yang dapat dilakukan adalah berinovasi dalam pembuatan media pembelajaran. Dalam pembuatan media pembelajaran membutuhkan ide kreatif, sarana dan prasarana yang mendukung dari pihak sekolah. Kenyataannya berbagai kendala untuk menciptakan media pembelajaran yang mengkontruksi peserta didik menghinggapi para guru sehingga adanya kesulitan untuk melakukan hal tersebut. Akibatnya, pembelajaran matematika masih dinilai tidak menarik oleh peserta didik sehingga masih banyak peserta didik yang hasil belajarnya dibawah nilai Kriteria Ketuntasan Maksimum (KKM.) Media pembelajaran berupa Lembar Kerja Peserta Didik (LKPD) yang dikolaborasikan dengan video ilustrasi berkonteks futsal pada pembelajaran matematika merupakan media pembelajaran yang mampu membangun pengetahuan peserta didik. Kegiatan Pengabdian ini bagi dilaksanakan di salah satu Madrsah Tsanawiyah (MTs) di Desa Duren melalui pelaksanaan kegiatan pembelajaran media pembelajaran berkonteks futsal. Melalui kegiatan ini guru yang mengahadapi kendala kurangnya sarana dan prasarana pendukung pembuatan media pembelajaran dapat terbantu untuk menciptakan pembelajaran yang menggunakan media pembelajaran dan hasil belajar peserta didik menjadi lebih baik, khususnya pada materi operasi bilangan bulat dan pecahan.

Abstract

Abstrak. Hasil belajar matematika masih rendah disebabkan kurangnya pemahaman peserta didik pada materi matematika yang dipelajari. Salah satu materi matematika yang penting dimiliki peserta didik adalah bilangan bulat karena materi ini digunakan pada hampir seluruh materi matematika dan matapelajaran lainnya seperti Ilmu Pengetahuan Alam (IPA). Salah satu pendukung proses pembelajaran agar mencapai tujuannya yaitu penggunaan media pembelajaran karena guru matematika dalam proses pembelajarannya memerlukan adanya media pembelajaran yang dapat memudahkan peserta didik mempelajari materi untuk mencapai tujuan pembelajaran. Media yang digunakan dalam kegiatan Pengabdian kepada Masyarakat (PkM) ini yaitu media cetak berupa lembar kerja peserta didik Lembar Kerja Peserta Didik (LKPD) dan media audio-visual. Kolaborasi media pembelajaran ini akan menjadikan kegiatan pembelajaran lebih hidup dan akan meningkatkan fokus peserta didik pada setiap tahap proses pembelajaran berlangsung. Tujuan dari pelaksanaan Pengabdian kepada Masyarakat ini adalah meningkatnya hasil belajar matematika peserta didik khususnya pada materi operasi dasar matematika sehingga peserta didik mampu menyelesaikan permasalahan matematika yang menggunakan operasi dasar matematika. Hasil kegiatan menunjukkan adanya ketertarikan peserta didik dan hasil belajar yang meningkat dilihat dari nilai tes sebelum dan sesudah pelaksanaan kegiatan PkM.

Abstract

Mathematical problem-solving abilities in trigonometry material remain a challenge for many students, partly because they lack self-directed learning skills to manage the learning process. This research aims to analyze the relationship between self-directed learning and students' mathematical problem-solving abilities in trigonometry material. The research approach is quantitative, using a correlational method. The research sample consists of 62 vocational high school students in Karawang Regency, selected through random sampling. The research instruments include a self-directed learning questionnaire and an essay test of problem-solving abilities. The questionnaire measures initiative, responsibility, self-regulation, and students' evaluative abilities in the learning process, while the problem-solving ability test assesses students' abilities to understand, plan, execute, and evaluate trigonometry problem solutions. Data analysis was conducted using the Pearson correlation test. The research results show a strong, significant positive relationship between self-directed learning and mathematical problem-solving abilities, with a correlation coefficient of r = 0.679 and a significance value of < 0.001. These findings indicate that increased self-directed learning tends to be followed by greater ability to solve mathematical problems.

Abstract

This quantitative study aimed to examine the simultaneous and partial effects of self-efficacy and gender on mathematics learning outcomes related to circle equations among high school students. Employing a multiple regression design, the research involved 139 twelfth-grade students from SMA Negeri 7 Tambun Selatan, selected via simple random sampling. Data were collected through a self-efficacy questionnaire analyzed using the Successive Interval Method and an essay-based test for learning outcomes. Multiple regression analysis, after fulfilling classical assumptions, revealed that self-efficacy and gender significantly influenced learning outcomes simultaneously (F = 1025, p < 0.00). Partially, self-efficacy emerged as a significant predictor, with a positive coefficient (β = 0.585, t = 5.969, p < 0.001), indicating that higher self-efficacy is associated with improved cognitive achievement. Conversely, gender showed no significant partial effect (p > 0.05). Additional correlation analysis indicated a stronger relationship between self-efficacy and learning outcomes in male students (  = 0.545) compared to female students (  = 0.348). Nonetheless, self-efficacy remained the primary explanatory factor for cognitive achievement in both groups. These findings underscore the dominant role of self-efficacy as the key determinant of success in learning circle equations, surpassing the influence of gender.
