The problem with holding teachers largely responsible for their students' learning is that many learning difficulties derive from emotional and family issues that are uncontrolled by the teacher. Teachers teach--with greater or lesser knowledge and creativity--and can be a catalyst for a child's learning but they do not control most elements of a child's life. Many children who do poorly academically have inadequate control over their thinking and behavior and the healing of these deficiencies, after which grades can improve, is not the province of education.
