This research is part of an experimental study using Problem Based Learning model to improve junior high school students' mathematical numeracy skills based on ethnomathematics. The purpose of this study is to determine the level of Validity, Reliability, Difficulty Index, and Discriminatory Power of the ethnomathematics-based numeracy ability test instrument for junior high school students. The instrument used was in the form of essay test questions from pretest and posttest questions. The calculation of validity, reliability, difficulty index, and discriminatory power used IBM SPSS Statistics 20. The results of this study showed that the pretest and posttest questions were valid with sig (2-tailed) values 0.05. The calculation results of the pretest questions showed that the essay question instrument fell into the reliable category, because the calculation result obtained was 0.690, making it suitable for use as an instrument for data collection. The difficulty level of pretest and posttest questions fell into the easy and moderate categories. The discriminatory power criteria of the questions were moderate and good. Based on these research results, the ethnomathematics-based student numeracy ability test instrument is suitable for use.

Training and assistance in writing scientific journal articles for students of Al Azhar Medan Superior High School is carried out as an effort to improve students' academic literacy. This activity is based on the low ability of students to write scientific papers systematically, even though they have high academic potential. The method of implementing activities was carried out through face-to-face training for three days and online/offline assistance for two weeks. The activity was attended by 25 students of grade XI, and was evaluated using pre-test, post-test, observation, and assessment of writing results. The results of the activity showed an increase in the average score from 58.2 to 82.4, the number of students who were able to compile complete articles increased from 4 to 20 people, and eight articles were declared worthy of publication. In addition, 92% of students stated that this activity was very beneficial. This activity shows that participatory training approaches and systematic mentoring are effective in improving students' scientific literacy. The program also contributes to the formation of an academic culture and sustainable scientific writing skills at the high school level.

This study aims to determine the effect of the Auditory, Intellectually, and Repetition (AIR) learning model assisted by the Kahoot application on students’ mathematical problem-solving ability and examine its effectiveness in the learning process. This experimental study used a pretest–posttest control group design. The population consisted of 55 tenth-grade students of SMKS Al Washliyah Pasar Senen 2 Medan. Probability sampling selected two classes: experimental (30 students) and control (25 students). Research instruments included problem-solving tests and learning effectiveness questionnaires. Results showed that the experimental class achieved a higher posttest mean score (46.33) than the control class (36.59). A t-test indicated a significant difference (Sig. 0.000 < 0.05). Questionnaire results showed a “very good” category with 87.8% and 85.28% for experimental and control classes, respectively. This proves that applying the AIR model assisted by Kahoot effectively improves students’ mathematical problem-solving ability.

Pembelajaran Matematika Realistik pada dasarnya adalah pemanfaatan realita dan lingkungan yang dipahami peserta didik untuk memperlancar proses pembelajaran matematika sehingga mencapai tujuan pendidikan matematika secara lebih baik daripada masa lalu. Proses pembelajaran matematika realistik menggunakan masalah kontekstual sebagai titik awal dalam belajar matematika. Siswa diberi kesempatan untuk mengorganisasi masalah dan mencoba mengidentifikasi aspek matematika yang ada pada masalah tersebut. Misalnya dalam penanaman pohon .Proses pembelajaran peranan guru bukan semata-mata memberikan informasi, melainkan juga mengarahkan dan memberi fasilitas belajar. Proses pembelajaran pada awalnya meminta guru untuk mengetahui kemampuan dasar yang dimiliki oleh siswa meliputi kemampuan dasarnya, motivasinya, latar belakang akademisnya, dan lain sebagainya.

Pengabdian kepada masyarakat merupakan proses implementasi keilmuan yang dipelajari di perguruan tinggi guna memberikan manfaat seluas-luasnya bagi masyarakat. Kegiatan pengabdian masyarakat ini bertujuan untuk mengenalkan anak-anak di RA-Nur Islam Kota Medan dengan organ-organ sensorik utama melalui penerapan model anatomi sensorik. Penerapan model anatomi sensorik dapat diintegrasikan ke dalam kurikulum pendidikan anak usia dini untuk memberikan pengalaman belajar yang konkret dan menarik. Pada kegiatan pengabdian masyarakat di RA-Islam Nur Kota Medan metode yang digunakana selama kegiatan pengabdian kepada masyarakat adalah metode kualitatif dengan pendekatan deskribtif dimana kegiatannya dimulai dari perencanaan/persiapan, pelaksanaan, dan evaluasi. Pada kegiatan ini kami menggunakan model anatomi sensorik ini agar dapat membantu siswa/I mengetahui dan memahami bagaimana organ-organ sensorik mereka bekerja. Memahami anatomi sensorik dapat membantu dalam merancang aktivitas yang mendukung pengembangan keterampilan motorik halus anak-anak, seperti kejelian dalam melihat, mendengar, merasakan sesuatu seperti menggunakan tangan dan jari dengan lebih terampil dalam menanggapi stimulus sensorik. Berdasarkan pada pengabdian masyarakat yang kami lakukan maka dapat dikatakan bahwa model anatomi sensorik terbukti menjadi model pembelajaran yang efektif dan menyenangkan bagi anak-anak di RA-Nur Islam Kota Medan.
