BEYOND COMMITMENT: TEACHER MOTIVATION AS THE DOMINANT DRIVER OF PROFESSIONAL PERFORMANCE IN INDONESIAN PUBLIC SENIOR HIGH SCHOOLS

Abstract

ABSTRACT

Teacher performance is an important factor in learning quality, yet studies examining the contributions of teacher commitment and work motivation among mathematics teachers remain limited. The issue matters because professional performance is related not only to job demands but also to psychological conditions underlying engagement. This study aimed to analyze the contributions of teacher commitment and work motivation to the performance of mathematics teachers in public senior high schools in East Lombok, both partially and simultaneously. A quantitative approach with a cross-sectional survey design was employed. The population comprised 120 mathematics teachers from 21 public senior high schools, with a sample of 92 teachers selected through proportional random sampling. Data were collected using a five-point Likert questionnaire and analyzed using multiple linear regression after meeting normality, linearity, and multicollinearity assumptions. The results showed that teacher commitment contributed positively and significantly to performance, while work motivation also contributed positively and significantly. Work motivation had a relatively stronger contribution than commitment in the simultaneous model. Together, both predictors made a significant contribution to teacher performance. In conclusion, improving teacher performance requires integrating stronger professional commitment with working conditions that sustainably support motivation.

ABSTRAK

Kinerja guru merupakan salah satu faktor penting dalam pencapaian mutu pembelajaran, tetapi kajian yang secara simultan menguji kontribusi komitmen guru dan motivasi kerja pada guru matematika SMA Negeri masih terbatas. Kondisi tersebut penting dikaji karena kinerja profesional tidak hanya berkaitan dengan tuntutan tugas, tetapi juga dengan kondisi psikologis yang mendasari keterlibatan guru dalam pekerjaan. Penelitian ini bertujuan menganalisis kontribusi komitmen guru dan motivasi kerja terhadap kinerja guru matematika SMA Negeri di Kabupaten Lombok Timur, baik secara parsial maupun simultan. Penelitian menggunakan pendekatan kuantitatif dengan desain survei potong lintang. Populasi penelitian terdiri atas 120 guru matematika pada 21 SMA Negeri, dengan sampel 92 guru yang dipilih menggunakan proportional random sampling. Data dikumpulkan melalui kuesioner Likert lima poin dan dianalisis menggunakan regresi linear berganda setelah memenuhi uji asumsi normalitas, linearitas, dan multikolinearitas. Hasil penelitian menunjukkan bahwa komitmen guru berkontribusi positif dan signifikan terhadap kinerja, sedangkan motivasi kerja juga berkontribusi positif dan signifikan. Motivasi kerja memiliki kontribusi relatif lebih kuat dibandingkan komitmen dalam model simultan. Secara bersama-sama, kedua prediktor memberikan kontribusi signifikan terhadap kinerja guru. Kesimpulannya, peningkatan kinerja guru perlu mengintegrasikan penguatan komitmen profesional dengan penciptaan kondisi kerja yang mendukung motivasi secara berkelanjutan.
