Abstract

Kegiatan pengabdian ini dilakukan bertujuan untuk mengenalkan metode jarimatika untuk anak-anak Boneana. Metode yang digunakan dalam pelaksanaan kegiatan yaitu metode transfer ilmu jarimatika dan metode talking stick modifikasi. Metode transfer ilmu diberikan untuk mengenalkan dasar-dasar metode berhitung menggunakan jarimatika setelah itu dipraktikan oleh anak-anak dengan menggunakan metode talking stick. Talking stick merupakan metode berbasis game sehingga dapat menambah semangat belajar. Hasil kegiatan menunjukkan anak-anak yang terdiri atas peserta didik jenjang sekolah dasar dan sekolah menengah menunjukkan antusiasme dalam belajar mandiri matematika. Pengenalan operasi hitung penjumlahan dan pengurangan menggunakan metode jarimatika telah dilaksanakan dengan lancar.

Abstract

This research aims to identify students' statistical literacy abilities, and this type of research is descriptive qualitative. The subjects in this research consisted of 24 Sociology Education students from Muhammadiyah University of Kupang taking statistics courses in the 2023/2024 academic year. The instrument used is an assignment consisting of 2 questions. Data analysis was done by analyzing students' answer documents to complete the assignments given. Students' statistical literacy abilities are identified using five statistical literacy competencies: understanding statistical concepts, insight into the application of statistical concepts, calculation and graphing skills, interpretation abilities, and visualization and communication skills. The research results show that more than 50% of students can fulfill statistical literacy competencies such as understanding statistical concepts, numeracy, interpretation, and communication skills. However, less than 50% of students do not meet competency in insight into the application of statistical concepts and visualization skills. Students' abilities in essential statistical literacy competencies still need to be improved because most students still have limitations in these competencies.

Abstract

The study conducted quantitative research using a True Experimental Design approach known as Pretest-Posttest Control Group Design, involving all grade X students of Senior High School. Cluster Random Sampling was used to select the experimental and control classes. Normality and variant homogeneity tests were conducted. Data analysis utilized a 5% significance level and paired sample t-test for hypothesis testing. Results indicated the REACT strategy effectively improved students' higher-order thinking skills. In the control class, a significant difference was found between pre-test and post-test scores, as well as in the experimental class. Observation sheet assessments showed an average score of 87.5, confirming successful application of the REACT strategy in the learning process. Therefore, the analysis demonstrates the superiority of the REACT strategy over conventional methods in enhancing the higher-order thinking skills of grade X students at Senior High School.

Abstract

Pengabdian Masyarakat merupakan salah satu pilar Tri Dharma Perguruan Tinggi, disamping dharma pendidikan dan pengajaran serta dharma penelitian. Seperti kita ketahui bersama, pelaksanaan penyembelihan hewan qurban, merupakan kegiatan yang dimulai dari sebelum – proses dan pasca penyembelihan hewan qurban. Ketiga tahapan tersebut merupakan satu rangkaian yang harus dilaksanakan oleh lembaga / panitia yang mengadakan acara penyembelihan hewan qurban. Nah tahapan yang sering dilupakan atau dianggap tidak perlu adalah tahapan pasca pelaksanaan penyembelihan hewan qurban. Padahal pada tahap pasca yang berbentuk evaluasi. Metode yang digunakan dalam kegiatan ini adalah metode ceramah dan metode praktek. Melalui metode ini guru-guru, masyarakat serta siswa/i langsung mendengarkan apa yang dimaksud dengan perhitungan daging sapi bersih oleh dosen dan bisa dibimbing langsung terkait dengan perhitungan rendemen sapi, hasilnya yaitu Setelah berat bersih sapi dan kambing dijumlah secara keseluruhan dan dikurangi permintaan sebesar 30 %. Hasilnya menjadi daging stok yang akan dibagikan kepada mereka yang berhak menerimanya Namun demikian panitia khususnya TIM MONITORING harus terus memantau perkembangan dan manakala ada yang tidak sesuai antara perhitungan dengan realisasi daging qurban, maka tim monitoring dapat koordinasi dengan bagian perhitungan untuk dilakukan langkah-langkah antisipasi dan mungkin juga perhitungan ulang

Abstract

This study investigates the impact of using GeoGebra as a geometric visualization tool on reducing mathematics anxiety among students in a Mathematics Education program. GeoGebra, an interactive software, enables dynamic visualization of geometric concepts, potentially fostering deeper conceptual understanding and alleviating anxiety in learning mathematics. A one-group pretest-posttest design was employed, consisting of three phases: preparation, implementation, and data analysis. Data were collected through a mathematics anxiety questionnaire administered before and after the intervention using Google Forms. The participants were 45 Mathematics Education students enrolled in an Analytical Geometry course. Data analysis involved tests of normality, homogeneity, and a paired sample t-test. The results indicate that: (1) GeoGebra effectively reduces students' anxiety in learning geometry; (2) its interactive visualizations enhance conceptual understanding and mitigate anxiety levels; (3) there is a statistically significant difference in anxiety levels before and after the use of GeoGebra; and (4) students reported a more enjoyable and less stressful learning environment, which increased their engagement with the course content. These findings suggest that integrating GeoGebra into geometry instruction can be a valuable pedagogical strategy for reducing mathematics anxiety and promoting meaningful learning experiences
