Efektivitas Model Discovery Learning dengan Bantuan Media Poster Digital terhadap Keterampilan Menulis Teks Berita Siswa Kelas IV SD

Abstract

abstrak— Keterampilan menulis merupakan kemampuan penting yang perlu dikembangkan sejak sekolah dasar karena berfungsi membentuk pola pikir logis, kreatif, dan komunikatif. Salah satu jenis tulisan yang dipelajari adalah teks berita yang menuntut penyajian informasi faktual, objektif, dan menarik. Pembelajaran yang melibatkan proses penemuan serta pemanfaatan media digital dinilai mampu meningkatkan kualitas belajar siswa. Penelitian ini bertujuan mengetahui efektivitas model Discovery Learning berbantuan poster digital dalam meningkatkan kemampuan menulis teks berita siswa sekolah dasar. Penelitian menggunakan metode quasi-experimental dengan desain one-group pretest–posttest. Subjek penelitian berjumlah 15 siswa kelas IV. Data diperoleh melalui tes menulis yang dianalisis menggunakan N-Gain dan uji t berpasangan. Hasil penelitian menunjukkan adanya peningkatan kemampuan menulis yang signifikan, terlihat dari nilai rata-rata pretest 69 yang meningkat menjadi 86 pada posttest. Nilai N-Gain mencapai 0,53 yang termasuk kategori tinggi, sedangkan uji t menunjukkan t hitung 9,645lebih besar daripada t tabel 2,144 pada taraf signifikansi 0,05. Temuan ini membuktikan bahwa Discovery Learning berbantuan poster digital efektif membantu siswa menghasilkan teks berita yang lebih jelas, menarik, dan sesuai kaidah melalui kegiatan identifikasi masalah, eksplorasi informasi, serta penyusunan solusi kreatif. Dengan demikian, model tersebut layak diterapkan dalam pembelajaran menulis teks berita.

Abstract—tulis Writing skills are essential abilities that need to be developed from elementary school because they help shape logical, creative, and communicative thinking. One type of writing studied is news text, which requires the presentation of factual, objective, and engaging information. Learning that involves discovery activities and the use of digital media is considered effective in improving students’ learning quality. This study aims to determine the effectiveness of the Discovery Learning model assisted by digital posters in improving elementary students’ ability to write news texts. The research employed a quasi-experimental method with a one-group pretest–posttest design. The subjects consisted of 15 fourth-grade students. Data were collected through a writing test and analyzed using N-Gain and paired t-test calculations. The results showed a significant improvement in writing skills, indicated by the increase in the average pretest score of 69 to 86 in the posttest. The N-Gain value reached 0.53, which falls into the high category, while the t-test revealed a t-value of 9.645 higher than the t-table value of 2.144 at a 0.05 significance level. These findings demonstrate that Discovery Learning assisted by digital posters is effective in helping students produce clearer, more engaging news texts that follow linguistic rules through activities of problem identification, information exploration, and creative solution development. Therefore, this model is suitable for use in news text writing instruction.
