Abstract

Making the right decisions can optimize resource utilization, increase operational efficiency, and strengthen competitive positions in the market. A decision, as a choice of action from various alternatives that fulfill one or more goals, has a significant impact on various related parties. Therefore, decision making is the main function for a leader, both in companies and public institutions. The technique of modifying data to increase its value and usefulness is known as data optimization. This entails converting unstructured data into a structured format, improving data quality, reducing duplication, and retrieving related information. This research was conducted using a narrative review model. The research method used is secondary data collected from various international journals, papers, and previous research papers used as data sources and analyzed by the author taking into account the problems considered in this research.

Abstract

This study investigates students' perceptions of instructional media employed in English language teaching at SMK 1 Tirtamulya Karawang. Despite the recognized significance of media in educational settings, there remains limited research addressing its comprehensive impact within vocational school contexts. Adopting a qualitative descriptive method, data were obtained through classroom observations and interviews with 18 tenth-grade students and their English teacher. The findings indicate that tools such as whiteboards, textbooks, laptops, and speakers contribute positively to students' enjoyment, engagement, and comprehension, while also supporting pronunciation and vocabulary development. Nevertheless, some students expressed negative perceptions, citing disinterest or fear of making mistakes. The research underscores the dual nature of media, both aiding and potentially hindering learning, and highlights the necessity for thoughtfully chosen media tailored to student needs. The implications suggest that educators should incorporate a variety of interactive tools—such as gamification or virtual reality—to cater to diverse learning preferences. Future studies are encouraged to apply mixed-method approaches to further evaluate media effectiveness. This research adds to the discourse on educational technology by addressing gaps in vocational education studies and offering practical recommendations for media integration.
