Lastly, the relationship between teaching approaches and students' behavior, and the relationship between teaching approaches and students' performance are both significant.Thus, the researcher therefore concludes that the null hypotheses stating that "there a significant no relationship between teaching approaches and students' behavior" and "there a significant no relationship between teaching approaches and students' performance are both rejected. Which implies that the alternative hypotheses are accepted which implies that there is a significant relationship between them.Based on the drawn conclusions resulted to the following recommendations: The researcher recommends that the teachers will retain the teaching approaches since is significant contributor to students learning; the teachers may have a standardize rubric in measuring students' performance in athletics events like running, jumping, and throwing; Teachers should create activities that will allow students to apply the newly acquired skills and assess their performance that will help them discover their talents and abilities in athletics events; and collaboration among teachers, Parents, Coaches and other stakeholders to support the physical development of the student.
