These relationships are a critical component to the role of an educator. Without them, students will most likely not perform as well longterm. In fact, according to Dr. Sara Rimm-Kaufman of UVA, they are necessary for better learning to take place.
If a student feels a personal connection to a teacher, experiences frequent communication with a teacher, and receives more guidance and praise than criticism from the teacher, then the student is likely to become more trustful of that teacher, show more engagement in the academic content presented, display better classroom behavior, and achieve at higher levels academically.
I hope more teachers take the time out of their academic schedules to spend with students on field trips. It is a great way of learning more about our student body and ensure they learn about us as more than just teachers.
