Latar Belakang: Proses pembelajaran sangat mempengaruhi tingkat keterampilan mahasiswa. Di era saat ini, metode pembelajaran konvensional cenderung membosankan dan kurang efektif, terutama untuk mata pembelajaran EKG dasar. Mahasiswa memiliki waktu yang singkat dalam menguasai mata pelajaran ini sehingga sulit dimengerti dan menjadi tantangan tersendiri. Data menunjukkan bahwa masih ada mahasiswa yang mendapatkan nilai kurang dalam interpretasi EKG. Oleh karena itu, perlu diterapkannya metode pembelajaran peer teaching sebagai alternatif untuk meningkatkan keterampilan interpretasi EKG dasar. Metode ini menekankan pada gaya belajar VARK. Tujuan: Penelitian ini bertujuan untuk mengetahui efektifitas metode pembelajaran peer teaching terhadap keterampilan interpretasi EKG dasar mahasiswa tingkat III sarjana keperawatan di ITEKES Bali. Metode: Penelitian ini menggunakan desain pre-eksperimen dengan one group pretest posttest design. Populasi berjumlah 120 mahasiswa tingkat III sarjana keperawatan ITEKES Bali dengan jumlah sampel 55 responden dengan teknik probability sampling yaitu simple random sampling. Hasil: Hasil penelitian uji wilcoxon sign rank test diperoleh p-value 0,000 menunjukkan bahwa p < 0,05 yang artinya Ha diterima, sehingga (H0) ditolak. Kesimpulan: Metode pembelajaran peer teaching efektif dalam meningkatkan keterampilan interpretasi EKG dasar mahasiswa tingkat III Sarjana Keperawatan di ITEKES Bali sehingga metode ini perlu dikembangkan lebih luas pada topik pembelajaran lainnya dalam mata kuliah gawat darurat.

Background: The learning process influences students’ skill. Nowadays, conventional learning methods tend to be boring and less effective, especially for basic ECG course. Students have a limited time to understand this course, so the difficulty of understanding becomes its challenges. Data showed that there were still students who had poor score in ECG interpretation. Therefore, the implementation of the peer teaching method is needed as an alternative to improve basic EKG interpretation skills. This method emphasizes the VARK learning style. Purpose: To identify the effectiveness of peer teaching learning method on basic ECG interpretation skill on the third year of nursing students at ITEKES Bali Method: This research employed pre-experimental design with one group pretest post-test design. The population was 120 nursing students from the third year at ITEKES Bali. There were 55 respondents recruited as the samples which were chosen by using probability sampling technique such as simple random sampling. Findings: Th result of Wilcoxon sign rank test showed that p-value 0,000 which meant Ha was accepted and Ho was rejected (p < 0.05). Conclusion: The peer teaching learning method is effective in improving the basic ECG interpretation skills of third-year Nursing students at ITEKES Bali, so this method needs to be developed widely for other learning topics in the emergency care course Keywords: Peer Teaching Learning Method, ECG Interpretation, Learning Effectiveness, VARK Learning Style, Basic ECG
