This study dealt with the influence of Teaching Strategies and Teacher’s Self-Concept to Students’ Engagement in learning among High School Teachers in Mawab, Davao de Oro.

Also this study utilized a quantitative-correlational design with 113 respondents among teachers in three chosen High schools’ in Mawab, Davao de Oro. The average weighted mean, Pearson-R, and multiple regression analysis were the statistical tool used in this study. Along with this, the result of the study revealed that the first independent variable which is the teaching strategies got an overall level of moderate, within its indicator; critical thinking, creativity, social skills and ICT skills, got a very high level. On the other hand, the second independent variable which is teachers’ self-concept got an overall level of very high, within its indicators; values, beliefs, student-centered approach and teacher-centered approach all got a high level. On the other hand, the dependent variable, affective engagement, behavioral engagement and cognitive engagement also got a very high level. Additionally, teaching strategies had moderate correlation towards students’ engagement in learning, while teacher’s self-concept got a high correlation towards students’ engagement in learning. Hence, this led to the rejection of null hypothesis in terms of teaching strategies and teachers’ self-concept. Also, in terms of Regression of teaching strategies, critical thinking, social skills, and ICT skills were domains that significantly influencing students’ engagement in learning, whilst, the regression of teacher’s self-concept revealed that, values, beliefs, and student-centered approach were domains that significantly influencing students’ engagement in learning.
