Kontribusi Pengalaman Mengajar, Motivasi Berprestasi dan Supervisi Akademik Terhadap Kinerja Guru SD Mitra Eduversal Seluruh Indonesia

Abstract

This study aims to determine the contribution of teaching experience, achievement motivation, and academic supervision by school principals to the performance of teachers at Eduversal partner elementary schools across Indonesia. This quantitative research employed a correlational approach and was conducted in six elementary schools from various regions, involving 270 teachers. A sample of 161 teachers was selected using Proportional Random Sampling and the Slovin formula. The research instruments were validated using product-moment correlation, and their reliability was tested with Cronbach’s Alpha. Preliminary analyses included tests for normality, linearity, and multicollinearity. Hypothesis testing was conducted using multiple regression analysis and partial correlation analysis. The findings revealed that collectively, teaching experience, achievement motivation, and academic supervision by school principals positively and significantly contributed to teacher performance. However, individually, teaching experience did not have a significant contribution, indicating that longer work experience does not necessarily lead to improved performance. In contrast, both achievement motivation and academic supervision by school principals individually showed positive and significant contributions, suggesting that higher teacher motivation and stronger academic supervision enhance teacher performance at Eduversal partner elementary schools across Indonesia.Penelitian ini bertujuan untuk mengetahui kontribusi pengalaman mengajar, motivasi berprestasi, dan supervisi akademik kepala sekolah terhadap kinerja guru di Sekolah Dasar (SD) Mitra Eduversal seluruh Indonesia. Penelitian kuantitatif dengan pendekatan korelasional ini dilakukan di enam SD dari berbagai daerah, melibatkan 270 guru. Sampel sebanyak 161 guru dipilih menggunakan teknik Proporsional Random Sampling dan metode Slovin. Instrumen penelitian divalidasi menggunakan korelasi product moment dan reliabilitas diuji dengan Alpha Cronbach. Uji prasyarat analisis mencakup uji normalitas, linearitas, dan multikolinearitas. Hipotesis diuji melalui analisis regresi ganda dan korelasi parsial. Hasil penelitian menunjukkan bahwa secara simultan, pengalaman mengajar, motivasi berprestasi, dan supervisi akademik kepala sekolah berkontribusi positif dan signifikan terhadap kinerja guru. Namun, secara parsial, pengalaman mengajar tidak memberikan kontribusi signifikan, menandakan bahwa lamanya pengalaman tidak menjamin peningkatan kinerja. Sebaliknya, motivasi berprestasi dan supervisi akademik kepala sekolah secara individu berkontribusi positif dan signifikan, mengindikasikan bahwa semakin tinggi motivasi dan kualitas supervisi, semakin baik pula kinerja guru di SD Mitra Eduversal seluruh Indonesia
