Abstract

This research and development (R&D) aimed at creating educational media designed to enhance skills in writing procedural texts. The research process followed eight key stages: identifying potential issues, data collection, product design, design validation, design revision, product trials, further product revisions, and concluding with usage trials. The participants in this study included fourth-grade students from Ngaliyan 05 Elementary School and Wonosari 02 Elementary School. The findings indicated a clear need among teachers and students for learning media to support their educational goals effectively. In response, the researchers developed the Zig-zag Book media based on the Pair Check Cooperative Learning method. This media encompasses a concise summary of the material, examples of procedural texts accompanied by visuals, student worksheets, and learning evaluations. Feedback from both students and teachers underscored several advantages of the developed media: it features an engaging design with bright colors that appeal to elementary school children, offers a variety of texts, images, examples, and practice questions, and presents precise instructions for use, making it user-friendly. The material is articulated succinctly, employing language and terminology that is accessible and easily understood. Field trials revealed that the media's feasibility was rated at 85% for the content and 93% for the overall quality. Furthermore, students' learning outcomes exhibited significant enhancement, with pre-test and post-test results yielding an impressive N-gain of 72.07%. This evidence suggests that the Zig-zag Book media, based on the Pair Check Cooperative Learning method, effectively improves students' writing skills.

Abstract

This study aims to develop and test the feasibility, practicality, and effectiveness of the Circle Time E-module through Linktree to improve students' narrative text content speaking skills. This research used the Research and Development (R&D) method with the Borg and Gall development model. The data collection techniques used were tests (pretest and posttest questions) and non-tests (observation, interviews, documentation data, and questionnaires). The data analysis technique in this study used the normality test, t-test, and gain test. The results of the feasibility test obtained a percentage of the assessment, namely from the media expert validator of 90.8% and the material expert of 90% so that the average was 90.4% with a very feasible category. The effectiveness of the Circle Time E-module through Linktree was proven through a t-test which showed a significance value <0.05 which means there is a significant difference between speaking skills before and after treatment with an N-gain test value of 0.662 on a small scale and 0.642 on a large scale which shows a medium category. Practicality is demonstrated by the positive response of 96% of teachers and 96.5% of students with very positive criteria. From these results, it can be concluded that the Circle Time E-module through Linktree is effective, feasible, and practical for improving narrative text speaking skills in Indonesian language learning for grade IV elementary school students.

Abstract

Keterampilan membaca permulaan memiliki peran penting dalam keberhasilan belajar siswa sekolah dasar. Hasil observasi di SD N Dempet 2 menunjukkan bahwa 43% siswa kelas 1 mengalami kesulitan dalam menguasai keterampilan ini. Penelitian ini bertujuan untuk 1) mengembangkan, 2) menguji kelayakan, dan 3) mengevaluasi keefektifan buku berjenjang berbasis metode Struktural Analitik Sintetik (SAS) dalam meningkatkan keterampilan membaca permulaan siswa kelas 1 SD. Penelitian ini menggunakan metode Research and Development (R&D) dengan model Borg & Gall yang dimodifikasi menjadi delapan tahapan sebagai berikut: potensi dan masalah, pengumpulan data, desain produk, validasi desain, revisi desain, uji coba produk, revisi produk, dan uji coba pemakaian. Desain buku berjenjang berbasis SAS untuk siswa kelas 1 di kembangkan 2 jenjang yaitu jenjang A dan jenjang B-1. Hasil validasi menunjukkan bahwa buku berjenjang berbasis SAS memiliki tingkat kelayakan yang sangat tinggi, dengan skor 94% dari ahli materi dan 95% dari ahli media. Uji efektivitas menggunakan t-test menunjukkan hasil yang signifikan, baik pada uji coba skala kecil (thitung = 4,929 > ttabel = 2,571) maupun uji coba skala besar (thitung = 14,055 > ttabel= 2,080) pada taraf signifikansi 5%.  Perhitungan N-Gain sebesar 0,8136 menunjukkan peningkatan keterampilan membaca permulaan dengan kategori tinggi. Dengan demikian, buku berjenjang berbasis SAS layak dan efektif dalam meningkatkan keterampilan membaca permulaan pada siswa kelas 1 SD.
