I cannot understate the importance of this small "chapter" within this course. Establishing & then maintaining positive relationships with students & their parents/guardians is SOOOOOO important. When students KNOW that their families support you, it actually can serve as a sort of "deterrent" to many poor choices and maladaptive behaviors.
Positive relationships also lead to students TRUSTING you, asking for assistance in other areas of their daily academic schedules. Building administrators NOTICE this positive interaction.
