Abstract

Dalam penelitian ini, digunakan pendekatan deskriptif kualitatif untuk memahami dan mengevaluasi kesalahan yang dilakukan oleh mahasiswa dalam menyelesaikan soal persamaan diferensial orde satu. Kajian ini melibatkan mahasiswa Prodi Pendidikan Matematika di Universitas Negeri Medan sebagai subjek penelitian, dengan jumlah sampel sebanyak 5 orang. Metodologi yang diterapkan meliputi penggunaan teknik dokumentasi, dimana data diperoleh dari hasil tes yang berisikan empat soal deskriptif terkait persamaan diferensial orde satu. Analisis Kesalahan mahasiswa terhadap persamaan diferensial orde satu menunjukkan bahwa masih terdapat kekurangan dalam pemahaman mereka terhadap materi tersebut. Hal ini dibuktikan dengan persentase kesalahan yang mencapai 60%, sementara hanya 40% jawaban yang benar. Penyebab utama dari kesalahan ini adalah rendahnya kemampuan penalaran mahasiswa dalam memecahkan soal-soal yang berkaitan dengan persamaan diferensial orde satu, berdasarkan data yang telah dikumpulkan dan dianalisis.

Abstract

Background: Literacy and numeracy are fundamental competencies in fostering critical thinking skills in early childhood; however, early childhood education teachers in Stabat District, Langkat Regency, face limitations in integrating literacy and numeracy instruction with the values of the Sustainable Development Goals (SDGs). Objective: This community service program aimed to enhance teachers’ competencies in implementing SDGs-based literacy and numeracy learning in a contextual and meaningful manner. Methods: The program employed a Participatory Action Research (PAR) approach over three months, comprising stages of socialization, training, and workshops; implementation of educational technology; mentoring; and evaluation. Data were collected using pre-test and post-test instruments, classroom observations, and teacher reflections, and were analyzed descriptively by comparing pre- and post-intervention conditions. Results: The findings indicate a significant improvement in teachers’ average understanding of literacy (from 56.4 to 82.1), numeracy (from 53.8 to 80.6), and the integration of the SDGs (from 48.2 to 79.3). In addition, one-way instructional practices decreased from 72.5% to 20.0%, while interactive learning increased to 80.0%, and the use of innovative learning media reached 85.0%. Conclusion: The SDGs-based literacy and numeracy approach effectively strengthened teachers’ pedagogical competencies and promoted more interactive, contextual, and sustainable early childhood learning practices.
