Over the years humans have developed ways of relating that is chemically based on hormones of love, compassion, gumption, and trust. Oxytocin has been identified as the chemical produced in response to the feeling of safety and protection one get when living in a community where the leader is satisfying their needs.
In the classroom we have a similar situation when learning something that is challenging. The leader, in this case the teacher, has to make sure that students are aware of the value, the 'worth' of their education. Teaching science is specially challenging due to the complex nature of its language, not only math is involved but particular nomenclature and vocabulary that comes from an intricate historical evolution.
So why am I thinking about this in relationship to my teaching?
It seems clear to me that when students come to class are in search among other things of a leader. The teacher as a coach has to be dependable and more important has to be a leader. A leader that has gain the trust of their students.
