Abstract

Background: Mathematics learning is frequently perceived as abstract and disconnected from students’ daily experiences. Ethnomathematics offers a culturally responsive approach by embedding mathematical concepts within community traditions. However, teachers often face challenges in analyzing classroom data due to limited familiarity with accessible statistical software. This community service program addressed the need to strengthen ethnomathematics-based instruction supported by digital data analysis tools, particularly Jamovi. Purpose of the Study: This study aimed to enhance teachers’ understanding of ethnomathematics and improve their competence in applying the Jamovi application for statistical data analysis in mathematics learning. Methods: The program employed a participatory training model consisting of preparation, implementation, and evaluation stages. Activities included socialization sessions, seven online workshops, and one offline session involving 50 mathematics teachers from the MGMP forum. Pre-tests, post-tests, product presentations, and satisfaction questionnaires were used to evaluate outcomes. Data were analyzed using descriptive statistics and Normalized Gain (N-Gain). Results: The findings indicate high participant satisfaction, with an average of 70.6% selecting “Strongly Agree.” Teachers’ mean scores improved from 66.56 (pre-test) to 85.76 (post-test), with an average N-Gain of 0.59 (medium-to-high category). The results demonstrate that integrating ethnomathematics with Jamovi effectively enhances teachers’ statistical literacy, technological competence, and ability to design contextual mathematics learning.

Abstract

ABSTRACT Practical learning in the automotive field requires students not only to understand the operating principles of vehicle components but also to apply them accurately in workshop activities. In the cooling system topic, limited practical learning media often hinder the learning process, resulting in learning experiences that do not fully reflect real workplace conditions. This situation encourages the use of a cooling system trainer as a learning medium designed to strengthen the connection between conceptual understanding and practical skills. This study involved 30 students of Class XI TKR 2 at SMK Negeri 8 Palembang, selected through a purposive sampling technique. Changes in students’ practical abilities were observed through pre- and post-learning practical tests and analyzed using normality testing, the Wilcoxon Signed Rank Test, and N-Gain analysis. The results revealed an increase in the average practical score from 49.53 to 84.80 after the implementation of the trainer-based learning activities. A significance value of 0.000 (<0.05) indicated a statistically significant improvement in students’ practical performance. Furthermore, the average N-Gain score of 0.68 was categorized as moderate, with an effectiveness level of 68.04%. These findings suggest that the cooling system trainer can provide a more engaging learning experience, enhance procedural understanding, and support the development of vocational competencies aligned with industry demands. Therefore, the media has considerable potential as an innovative alternative for practical learning in automotive vocational education. ABSTRAK Pembelajaran praktik pada bidang otomotif menuntut peserta didik tidak hanya memahami konsep kerja komponen kendaraan, tetapi juga mampu menerapkannya secara tepat dalam kegiatan bengkel. Pada materi sistem pendingin, keterbatasan media praktik sering kali menyebabkan proses pembelajaran kurang optimal sehingga pengalaman belajar yang diperoleh siswa belum sepenuhnya mencerminkan kondisi kerja nyata. Kondisi tersebut mendorong pemanfaatan media trainer sistem pendingin sebagai sarana pembelajaran yang dirancang untuk memperkuat keterkaitan antara pemahaman konseptual dan keterampilan praktik. Kajian ini melibatkan 30 siswa kelas XI TKR 2 SMK Negeri 8 Palembang yang dipilih melalui teknik purposive sampling. Perubahan kemampuan praktik diamati melalui pemberian tes sebelum dan sesudah penggunaan media, kemudian dianalisis menggunakan uji normalitas, Wilcoxon Signed Rank Test, dan perhitungan N-Gain. Hasil pengolahan data memperlihatkan peningkatan rata-rata skor dari 49,53 menjadi 84,80 setelah siswa mengikuti pembelajaran dengan media trainer. Nilai signifikansi sebesar 0,000 (<0,05) menunjukkan adanya perubahan yang bermakna pada capaian praktik siswa. Selain itu, rata-rata N-Gain sebesar 0,68 berada pada kategori sedang dengan tingkat efektivitas mencapai 68,04%. Temuan ini memperlihatkan bahwa penggunaan media trainer sistem pendingin mampu menciptakan pengalaman belajar yang lebih aktif, memperkuat penguasaan prosedur kerja, dan mendukung pembentukan kompetensi vokasional yang selaras dengan kebutuhan dunia kerja. Dengan demikian, media tersebut berpotensi menjadi alternatif inovasi pembelajaran praktik pada pendidikan kejuruan otomotif.
