Abstract

In the era of digital transformation, teacher professionalism has become a critical determinant of educational quality, yet its relationship with self-regulatory capacity and digital preparedness remains underexplored in developing-country contexts. Empirical evidence from Indonesian schools indicates that teachers' levels of self-management and digital readiness remain varied and suboptimal, potentially undermining effective teaching performance in technology-integrated learning environments. This study aimed to examine the partial and simultaneous effects of self-management and digital readiness on teacher professionalism among junior high school teachers in Paal Dua District, Manado City, Indonesia. A quantitative explanatory research design was employed. Data were collected via a validated Likert-scale questionnaire administered to 85 respondents, selected using the Slovin formula (e = 0.05) from a population of 108 teachers across eight schools. Multiple linear regression analysis was conducted using IBM SPSS Statistics. Self-management had a positive and significant effect on teacher professionalism (β = 0.434, t = 4.911, p < 0.001), while digital readiness also exerted a positive and significant influence (β = 0.413, t = 4.681, p < 0.001). Self-management emerged as the more dominant predictor. Simultaneously, both variables significantly predicted teacher professionalism (F = 23.115, p < 0.001), explaining 36.1% of its variance (R² = 0.361). The integration of self-management capabilities and digital readiness constitutes a key determinant of teacher professionalism in digitally transforming educational settings. These findings provide an empirical basis for school administrators and education policymakers to design targeted teacher professional development programs that simultaneously strengthen self-management competencies and digital readiness.

Abstract

Science laboratory management and the availability of educational facilities are critical factors in supporting effective science learning; however, suboptimal laboratory utilization and limited instructional resources remain persistent challenges in many Indonesian schools, particularly at the junior secondary level. This study aims to analyze the influence of science laboratory management and educational facilities on students' learning interest at public junior high schools in Paal 2 District, Manado City. A quantitative ex post facto approach was employed, with data collected through validated structured questionnaires from 163 students selected using proportional random sampling from a population of 275 Grade VIII students. Data were analyzed using multiple linear regression with partial (t-test) and simultaneous (F-test) hypothesis testing. The results demonstrated that: (1) science laboratory management had a positive and significant influence on students' learning interest (β = 0.452, t = 10.986, p < 0.001); (2) educational facilities had a positive and significant influence on students' learning interest (β = 0.356, t = 5.071, p < 0.001); and (3) both variables simultaneously exerted a significant effect on learning interest (F = 78.235, p < 0.001), collectively explaining 49.4% of the variance (R² = 0.494). Laboratory management emerged as the stronger predictor (standardized β = 0.620) compared to educational facilities (standardized β = 0.286). These findings indicate that well-managed laboratories combined with adequate educational facilities are essential to fostering higher levels of student interest in science learning, implying that school administrators and policymakers should prioritize systematic laboratory management alongside facility improvement to enhance the quality of science education.

Abstract

Teacher performance is a critical determinant of educational quality and plays a central role in achieving national educational goals, yet it remains suboptimal in many school settings due to weak leadership and organizational dynamics. This study aims to empirically analyze the influence of the principal's transformational leadership and organizational culture—both partially and simultaneously—on junior high school teacher performance in Paal Dua District, Manado City. A quantitative approach with an associative ex-post facto method was employed, with data collected from 85 teachers selected via proportionate stratified random sampling from a population of 108 using the Slovin formula; data were gathered through Likert-scale questionnaires tested for validity and reliability. The multiple linear regression analysis yielded the equation Y = −0.317 + 0.495X1 + 0.432X2. Transformational leadership had a significant positive partial effect on teacher performance (t = 8.794, Sig. = 0.001 < 0.05), as did organizational culture (t = 6.853, Sig. < 0.001). Simultaneously, both variables produced a significant combined effect (F = 61.679, Sig. = 0.001 < 0.05), with a coefficient of determination (R²) of 0.601, indicating that 60.1% of variation in teacher performance is explained by the two predictors. It is concluded that the synergy between an inspiring principal and a conducive organizational culture is the primary determinant in optimizing teacher professionalism. These findings imply that educational policymakers should integrate transformational leadership development with organizational culture strengthening as a unified strategy for improving teacher performance in Indonesian junior high schools.
