How do you educate a teacher so brainless/racist that she assigns students to give 3 good reasons for slavery? How do you educate a principal so brainless/racist that he defends the action by saying the assignment was intended to spark debate? Debate about what? About how good it felt for the slave owners? How much wealth the slaves produced? No, Mr. Van Dellen, an inservice about cultural insensitivity isn't going to fix this problem.

The problem is the inability of a huge proportion of teachers and administrators to think critically. 

Teachers need education. Too many of them come to the classroom with a credential but little ability or inclination to use their powers of reason. 

Many, if not most, teachers have no idea how to teach kids to use their brains to separate truth and falsehood.

Step number one is to evaluate teachers' abilities effectively. Then the top 15% of teachers should be used to teach the average teachers how to think analytically.

A private Christian school in Wauwatosa, Wisconsin, is under fire after asking fourth-graders to lay out three “good” reasons for slavery as part of a homework assignment.

On Monday, the students at Our Redeemer Lutheran School were handed a social studies worksheet that told them to “give 3 ‘good’ reasons for slavery and 3 bad reasons.”...

Principal Jim Van Dellen sent a letter to parents with an apology and said that the teacher didn’t properly describe the task to students,according to the station.

[So, Mr. Van Dellen, why don't you explain the "proper" way to describe the task?]

The assignment was intended to spark debate in the class, he told Fox 6, adding that it has been pulled from the curriculum.

Brown-Berry shared an update on Facebook stating that she met with the principal and that he agreed to mandate “cultural diversity/cultural competency inservice [training for faculty] to prevent this from happening again.”...
