Abstract

Guru memiliki peranan yang sangat penting karena mereka merupakan jantung pendidikan dalam menciptakan peserta didik yang memiliki sikap, pengetahuan dan keterampilan yang baik. Untuk mencapai tujuan tersebut, guru harus memiliki kompetensi (profesional, pedagogik, sosial dan kepribadian) dan keterampilan dasar (keterampilan bertanya, memberikan penguatan, mengelola kelas, membimbing kelompok kecil, membuka dan menutup kelas, dan menggunakan variasi stimulus) yang mumpuni (Sanjaya, 2006; Djamarah, 2014). Di abad 21, guru tidak hanya memiliki kompetensi dan keterampilan dasar dalam mengajar saja, tetapi juga harus mampu menggunakan ICT dalam proses pembelajaran karena perkembangan teknologi dan informasi memberikan dampak dalam dalam berbagai aspek kehidupan. Salah satu yang dapat dilihat dalam fenomena sehari-hari adalah penggunakan alat komunikasi berupa telepon genggam (cell phone). Hampir sebagian besar masyarakat Indonesia dimulai dari anak-anak hingga orang dewasa menggunakan telepon genggam dengan berbagai tujuan mulai dari menelepon, mengirim pesan, menjelajahi informsi secara online, menonton video dan mendengarkan musik secara online maupun offline, serta melakukan transaksi perbankan (Koller, Foster, & Wright, 2008) Teknologi dan informasi yang berubah sangat cepat di abad 21 ini menjadi sebuah tantangan bagi guru dan sekolah untuk dapat memberikan bekal kepada peserta didik dalam menjawab tantangan yang akan mereka hadapi di kehidupan mendatang. Untuk menghadapi tantangan tersebut, guru harus melakukan proses pembelajaran yang sesuai dengan karakteristik dan kebutuhan peserta didik di masa depan serta relevan dengan perkembangan zaman. Kompetensi, keterampilan dasar dan penguasaan terhadap penggunaan teknologi di kelas juga perlu didukung oleh kreativitas dan inovasi yang dilakukan oleh guru dalam pembelajaran di kelas. Salah satu kreativitas dan inovasi yang dapat dilakukan adalah mengembangkan media pembelajaran yang sesuai dengan karakteristik dan kebutuhan peserta didik.

Abstract

This study explores the impact of digital technology on the effectiveness of the teaching and learning process through an examination of infrastructure services in a secondary school. For this purpose, field observations and a literature review were employed. The main findings indicate that the available digital technology infrastructure—including hardware (45 computer/laptop units with a 1:3 ratio, projectors in 36% of classrooms, and 60% of students owning personal devices), internet network (50 Mbps Wi-Fi covering 40% of classrooms), free digital platforms (Google Classroom, YouTube Edu, e-books, and simulations), as well as technical support (2 IT staff, maintenance every 6 months, official policies, and teacher training twice a year)—has supported positive outcomes in learning digitalization efforts. Descriptive and theoretical analysis shows that digitalization initiatives yield positive impacts, including enhanced accessibility, interactivity, motivation, and learning outcomes. However, potential negative impacts exist, such as digital divides, distractions, and unequal access due to suboptimal infrastructure. The study's conclusion emphasizes the importance of digital infrastructure service capacity and user readiness as key success factors. Recommendations include equitable infrastructure development (improving network coverage and device availability), additional technical resources, and ongoing teacher training to optimize the effectiveness and efficiency of teaching and learning in school environments.
