In her paper ‘Knowing, Believing and the Teaching of English’, quoted above, Pamela Grossman outlines just some of the key challenges faced by those who try to define the knowledge English teachers require.
Here is a summary:
“Julius Segal’s work on the factors that help kids overcome adversity is particularly powerful. He found that the common denominator among kids who’d overcome great hardship to succeed was the presence of a “charismatic adult” in their lives. Segal defined that person as an “adult from whom children gather strength,” and specifically said often that person is a teacher.”
