It is, realistically, humanly impossible. Further, it has led to the decline in the teaching profession and our inability to recruit and retain teachers who can read and write themselves. In addition, were teachers working with students who were in attendance by choice, leaving their personal adolescent problems outside the classroom door, even having paid a tuition to attend, perhaps their odds for success would be increased. Even elementary school teachers are only responsible for the learning of 25 or 35 students a year. And, generally speaking, parents are the most supportive in the earlier years.
Secondary teachers have five times the number of students, less support, and higher expectations.
Then simply give it to us. But please stop blaming us.
