Abstract
The purpose of this study was to determine the mediating role of personality traits of teachers on the relationship between teaching effectiveness and student productivity among grade 12 students in private schools. Quantitative non-experimental research utilizing descriptive correlational technique and mediation analysis were employed in this study. The data were gathered from 172 grade 12 students in private schools through stratified random sampling utilizing proportional allocation. Data was collected through survey questionnaires. The statistical methods used in data computation and hypothesis testing at the alpha 0.05 level of significance include Mean, Pearson-r, and Structural Equation Modelling (SEM) with mediation analysis. Results showed that the level of the role of personality traits of teachers, teaching effectiveness, and student productivity are at all high levels. Results revealed that the relationship between teaching effectiveness and student productivity, between teaching effectiveness, and the role of personality traits of teachers, and student productivity among grade 12 students in private schools all have a significant relationship. Results also revealed that the role of personality traits of teachers has partially mediated the relationship between teaching effectiveness and student productivity. It signifies that teachers may look into other factors that are affecting the student’s productivity and teaching effectiveness. It means, teachers may also consider the role of teacher personality traits of students specifically extraversion, agreeableness, conscientiousness, neuroticism, and openness, as they partially mediate or significantly affect the relationship between teaching effectiveness and student’s productivity.
