At the end of my daughter's freshman year, her science teacher went out on maternity leave. She was replaced by a substitute who showed "An Inconvenient Truth" to make the case for global warming. Then she gave her students an assignment to argue whether or not they thought global warming was true.
I gave my daughter the article about the UK judge who ruled that "An Inconvenient Truth" couldn't be shown in school without equal time in opposition, because the movie had nine glaring mis-statements of fact.
My daughter used that article as the basis for a rebuttal of the movie. The teacher returned the essay, with the written comment: "That's not proof." Like "An Inconvenient Truth" is.
When the report cards came out on the day of school, the substitute gave my daughter a full letter grade lower than her past grades, and than was justified by her test scores for the quarter.
That is so wrong but I am not surprised. I have heard similar stories.
No wonder our country is in the shape it is in. Our children are exposed to propaganda, even in the first grade.
Arguing with these teachers is a waste of energy. Many of them are not very bright and are easily threatened by opposing views. What a mess.
