Abstract

Literasi numerasi merupakan salah satu kompetensi dasar yang menjadi prioritas kebijakan pendidikan nasional melalui Kurikulum Merdeka dan Asesmen Kompetensi Minimum (AKM), namun implementasinya di lapangan masih menghadapi kendala, terutama pada satuan pendidikan dengan akses pengembangan profesional guru yang terbatas. SD Negeri 091518 PNP Tonduhan, sebuah sekolah dasar di kawasan perkebunan PT Perkebunan Nusantara, menghadapi persoalan tersebut karena guru masih memaknai numerasi secara sempit sebagai kemampuan berhitung dan belum terbiasa merancang pembelajaran kontekstual maupun asesmen berbasis AKM. Kegiatan pengabdian ini bertujuan meningkatkan pemahaman dan kompetensi guru dalam menerapkan literasi numerasi melalui pendekatan sosialisasi, workshop, dan simulasi yang dilaksanakan pada 11–12 November 2024 dan diikuti oleh sepuluh guru. Metode pelaksanaan mencakup tahap persiapan, koordinasi dengan sekolah, observasi awal, pemaparan konsep, workshop penyusunan soal kontekstual, simulasi analisis soal berbasis AKM, serta refleksi bersama, dengan evaluasi keberhasilan didasarkan pada observasi proses, hasil diskusi kelompok, produk pembelajaran yang dihasilkan guru, serta refleksi dan umpan balik peserta. Hasil kegiatan menunjukkan peningkatan pemahaman konseptual guru mengenai literasi numerasi, tumbuhnya kemampuan menyusun contoh soal berbasis konteks lokal perkebunan, serta kesadaran guru non-matematika bahwa numerasi merupakan tanggung jawab lintas mata pelajaran. Kendala utama berupa keterbatasan waktu efektif dan sarana teknologi diatasi melalui penyesuaian jadwal dan simulasi luring, sementara keberlanjutan program dirumuskan melalui rencana pendampingan berkala dan pembentukan komunitas belajar guru.

Abstract

Pertimbangan dalam pemilihan media pembelajaran adalah SECTIONS (Student, Ease of use, Cost and time, Teacher and selection media, Interaction, Organizational, Networking, Security and privacy) atau dalam bahasa Indonesia dapat disebut siswa, mudah digunakan, biaya dan waktu, pemilihan media berdasarkan pembelajaran, interaksi, pengolahan masalah, membangun jaringan ilmu pengetahuan, dan keamanan. Salah satu hal penting yang harus diperhatikan dalam mengembangkan media koran digital adalah ketepatan pemilihan materi yang nyata, yang digunakan dalam kehidupan nyata pengguna. Media Koran Digital merupakan salah satu solusi dalam pengembangan bahan ajar. Hal ini diasumsikan bahwa hasil belajar PKn tidak dapat dilaksanakan dengan hanya satu media pembelajaran seperti buku paket PKn. Sebagaimana dipahami bersama bahwa saat ini kita berada dalam suatu dasawarsa dimana kecepatan dan intensitas lalu lintas dan komunikasi antar bangsa meningkat secara cepat. Melalui jalur elektronik misalnya, kontak lintas batas atau komunikasi antar bangsa di seluruh penjuru dunia bisa terjadi hanya dalam hitungan detik saja. Tentu saja informasi itu didapatkan dengan membaca dan mendengar dengan menggunakan media pembelajaran yang digunakan guru sebagai pendidik mempunyai peranan yang sangat penting untuk menjalankan efektifitas pembelajaran di kelas, salah satu indikatornya adalah guru harus mampu memanfaatan teknologi informasi dan komunikasi untuk meningkatkan efisiensi dan efektifitas dalam pembelajaran. Teknologi pendidikan mempunyai fungsi dalam proses pembelajaran mengatasi berbagai kesulitan dan mempermudah proses pembelajaran sesuai dengan karakteristik dan kondisi dimana teknologi tersebut diterapkan.
