PENGEMBANGAN MEDIA PEMBELAJARAN BERBASIS WEBSITE MELALUI GOOGLE SITES UNTUK MENINGKATKAN HASIL BELAJAR SISWA PADA MATERI MICROSOFT OFFICE KELAS X SMK

Abstract

ABSTRACT

Informatics learning on Microsoft Office topics at SMK NU 1 Karanggeneng frequently encounters challenges related to the limited availability of interactive practice media and device memory constraints when installing additional applications. These instructional issues were addressed through the development of INFORSPACE, a Google Sites-based learning platform that integrates Microsoft Word, Microsoft Excel, and Microsoft PowerPoint modules into a single web ecosystem accessible without installation. The application of the Research and Development approach based on the ADDIE model encompassed the analysis, design, development, implementation, and evaluation stages. Feasibility testing by a media expert validator yielded a assessment percentage of 95 percent, categorized as excellent. Field implementation involving 30 Grade X Digital Business students demonstrated a significant shift in mean competency scores, rising from 64.87 on the pretest to 89.77 on the posttest, representing an increase of 24.90 points. Hypothesis testing using a paired-samples t-test confirmed a statistically significant difference in learning achievements (t(29) = 17.06; p < 0.001). These empirical findings demonstrate that the utilization of INFORSPACE media is effective in improving students' mastery of Microsoft Office content, while simultaneously providing an alternative digital learning resource that is flexible, structured, and responsive to the needs of vocational education.
