This study examined the factors influencing the proposed model for research productivity of public-school teachers in the Division of Quezon, focusing on engagement, self-efficacy, positive emotions, and research collaboration. Specifically, it determined the effects of these variables on research productivity and analyzed their direct and mediating relationships. A quantitative descriptive-correlational design was employed, integrating Structural Equation Modeling (SEM) to assess both direct and indirect effects and to validate the proposed model. Data were collected from 150 purposively selected elementary and secondary teacher-researchers using a validated 125-item Likert-scale questionnaire measuring engagement, efficacy, positive emotions, collaboration, and research productivity.

Descriptive statistics (mean and standard deviation) were used to determine the levels of variables, while inferential statistics, including Pearson’s correlation and multiple regression analysis, examined relationships and predictive effects. Findings revealed that both engagement and self-efficacy have significant positive effects on research productivity. However, positive emotions and research collaboration did not significantly mediate the relationship between engagement or efficacy and productivity; still, these variables help strengthen the impact of both engagement and efficacy on research productivity. The results suggest that both positive emotions and research productivity contribute to teacher engagement and efficacy, and that positive emotions play a more critical role in enhancing research productivity. Thus, fostering both variables of research practices is essential in strengthening teachers’ research output and advancing professional development in public schools. Based on these findings, the model of research productivity indicates that although positive emotions and research collaborations are significant variables for engagement and efficacy among teacher researchers, they are not the primary determinant of research productivity, highlighting this as a vital topic for further advancement in professional practices for educators.
