Abstract

Fenomena menghargai kebhinekaan adalah isu yang sangat strategis pada saat ini. Hal ini menjadi tantangan tersendiri bagi masyarakat secara umum dan mahasiswa secara khusus. Tantangan yang dihadapi mahasiswa dalam berinteraksi dengan sesama, seperti stereotip, diskriminasi, dan polaritas pemikiran, dapat menghambat pemahaman dan penghargaan terhadap keberagaman. Dalam era globalisasi, mahasiswa diharapkan menjadi agen perubahan yang mampu mengelola perbedaan dan mempromosikan nilai-nilai toleransi. Berdasarkan pemikiran tersebut, menanamkan sikap menghargai kebhinnekaan tersebut dianggap sangat penting. Dalam kegiatan ini, metode yang digunakan adalah sosialisasi dan pelatihan yang dirancang untuk meningkatkan kesadaran mahasiswa tentang kebhinnekaan. Kegiatan ini diawali dengan pretest untuk mengukur pemahaman awal peserta, diikuti dengan pemaparan materi, diskusi, dan refleksi. Setelah kegiatan, posttest dilakukan untuk mengevaluasi peningkatan pemahaman peserta mengenai kebhinnekaan. Hasil dari kegiatan ini menunjukkan adanya peningkatan signifikan dalam pemahaman mahasiswa tentang pentingnya kebhinnekaan dan tantangan yang dihadapi dalam interaksi sosial. Diskusi ke depan menekankan perlunya program-program berkelanjutan yang mendukung pendidikan multikultural dan dialog antarbudaya di lingkungan kampus. Dengan demikian, diharapkan mahasiswa dapat berkontribusi secara positif dalam membangun masyarakat yang lebih adil, damai, dan inklusif di masa depan.

Abstract

The 4C skills—Critical Thinking, Creativity, Communication, and Collaboration—are essential for preparing students to navigate 21st-century challenges. However, results from PISA 2022 and Indonesia's Education Report 2024 reveal that foundational competencies remain low, particularly in rural contexts. This study aims to explore the manifestation of 4C skills among ninth-grade students at SMP Budhi Dharma Balige, North Sumatra, through performance on PISA-based mathematics questions. Employing a qualitative descriptive design, data were collected from 31 students using two PISA tasks and an unstructured teacher interview. Responses were assessed using a rubric-informed framework, and analysis followed the Miles and Huberman model. Results show that while students demonstrate strong communication and procedural reasoning (96.77% correct in Q1 Part 2), performance in critical thinking and argumentation remains limited (only 35% success in Q2 Part 3). The main barrier is the lack of integrated instructional strategies that promote higher-order and collaborative learning. The study concludes that while 4C skills are beginning to develop, their progression is fragmented and requires targeted pedagogical reforms. Recommendations include the use of project-based learning, culturally responsive instruction, and formative assessments to ensure equitable 4C development in under-resourced schools.
