Abstract

Artikel ini membahas tentang penggunaan aplikasi Kahoot sebagai media pembelajaran Bahasa Inggris dan agama kristen. Kegiatan pengabdian ini dilakukan untuk meningkatkan kemampuan berbahasa Inggris melalui aplikasi Kahoot dan bimbingan pembelajaran Pendidikan agama Kristen melalui konseling,sekaligus untuk membimbing siswa untuk selalu disiplin dalam kegiatan pembelajaran di sekolah. Tujuan penelitian ini adalah untuk mengetahui apakah aplikasi Kahoot dapat meningkatkan minat belajar Bahasa Inggris siswa. Berdasarkan analisis yang dilakukan ditemukan bahwa aplikasi Kahoot dapat meningkatkan minat belajar siswa. Kahoot bisa digunakan untuk mengeksplorasi pengetahuan dan pemahaman siswa tentang topik pembelajaran dan membantu siswa untuk memvalidasi pemahaman. Meskipun penggunaan aplikasi Kahoot masih belum dikalangan siswa SMA dengan mudahnya fituryang ada, aplikasi ini dapat memungkinkan seseorang untuk belajar dan beradaptasi dengan cepat.

Abstract

The rapid development of digital technology has significantly influenced instructional practices in mathematics education, particularly in the teaching of abstract and conceptually demanding topics such as geometry and trigonometry. One foundational topic that frequently presents learning challenges is right triangle geometry, which underpins students’ understanding of trigonometric ratios and their applications. This study aims to describe university students’ responses to the use of GeoGebra as a technology-assisted learning tool in right triangle geometry instruction. Employing a descriptive survey research design, the study involved 30 first-year students enrolled in a Mathematics Education program at Universitas PGRI Palembang. Data were collected through a structured student response questionnaire administered after a GeoGebra-assisted learning session. The questionnaire examined four aspects: perceived conceptual understanding, learning motivation, interactivity, and ease of problem solving. Data were analyzed using descriptive statistics in the form of percentage distributions. The findings indicate that students demonstrated positive to very positive responses across all assessed aspects, particularly in learning motivation and perceived conceptual clarity supported by visual representations. While the results do not claim instructional effectiveness or learning gains, they suggest that GeoGebra is perceived as a supportive and engaging tool for learning right triangle geometry. The study contributes descriptive evidence regarding students’ perceptions of GeoGebra-based instruction and provides pedagogical insights for mathematics educators integrating digital tools in geometry learning.

Abstract

Background: In the current STEMI-based model for diagnosing acute myocardial infarction (AMI), many patients classified as NSTEMI may actually have undetected acute coronary occlusion. As a result, these patients miss the opportunity for timely reperfusion therapy and experience worse outcomes than those with non-occlusive myocardial infarction (NOMI). To address this issue, a revised paradigm has been proposed that differentiates occlusion MI (OMI) from non-occlusion MI (NOMI). Methods: This systematic review included eight studies published between 2020 and 2024. All studies evaluated patients with acute coronary syndrome (ACS), comparing diagnostic performance and clinical outcomes between the traditional STEMI/NSTEMI paradigm and the emerging OMI/NOMI paradigm. The studies employed various designs, including retrospective cohorts, case-control analyses, and cross-sectional studies, to assess diagnostic accuracy and treatment outcomes. Results: Evaluation of ECG diagnostic performance showed that OMI-specific ECG patterns had significantly higher sensitivity (86%) and diagnostic accuracy (89%) compared to standard STEMI criteria (41% sensitivity, 77% accuracy). Several studies reported substantial delays in recognition and management of OMI when relying solely on STEMI criteria. Evidence consistently demonstrated that patients with OMI, especially those misclassified as NSTEMI, had outcomes equal to or worse than those with STEMI. Conclusion: The OMI paradigm highlights major quality gaps in the emergency care of ACS patients. Transitioning from the traditional STEMI/NSTEMI model to OMI/NOMI classification can improve diagnostic precision, identify care delays, and guide quality improvement interventions to optimize patient outcomes.
