You'll see themes ranging from multiculturalism to junk science, historical revisionism to environmentalism. The textbooks are awful. I've made sure to point out all the errors to the children.
I'll give you some examples.
In one social studies textbook, you'll quickly get a politically correct historical version of America. The textbook lies and claims that America has always been a multicultural nation, and implies that everyone who has come here has held onto their individual culture. Directly below this paragraph, you see pictures of children who are supposed to have represented America throughout history. However, they don't look American, for most are decked out in Asian, Middle Eastern, African, or whatever foreign clothing. You do see a few "American style" kids into the mix. However, they are in the minority. In fact, the textbooks portray Europeans as having been the minority throughout the U.S., both in the past and in the present.
Another example was an extreme form of junk science. The lesson plan was to work on a particular assignment within the reading and writing workbooks. Upon turning to the lesson pages, it was indicated that you were to read the story and fill in the blank spaces from a glossary of words located above in a box. The story could have been right out of the environmentalist handbook. As an individual who studied meterology in college, I quickly knew that the arguments were bogus. The story made the statement that if one were to cut down all the trees and root systems within a particular area that a desert would be the direct result. As some who knows about weather and climate, it is a fallacy to say that climate is a byproduct of vegetation. The opposite is true. Vegetation is a byproduct of the climate. Climate is based upon different criteria, including wind belts, topography, proximity to lakes, oceans and rivers, areas that experience clashes in air masses, the jet stream, etc. However, vegetation is not one of those reasons. The lesson was a way of indoctrinating the kids into believing that if you cut down the trees, everything's going to be a desert, and that life would cease to be as it is. Mind you, this was in reference to only one particular area, not the whole earth.
I've seen history/social studies textbooks give too much emphasis to the "Native Americans" and too little to our Founding Fathers. Furthermore, some of these textbooks make the colonists out to be bad people, whereas the Indians are seen as good.
I've seen history textbooks refer to Cortes as destroying the ancient government of Mexico. Though they were right in terms of the killing that went on.
I've seen "Character Assemblies" in the schools that are nothing more than a subtle form of secular humanism. I've seen third grade children singing, "You can't tell me what to do. I don't have to do what you say. What's right is what's in my mind", etc. Mind you, these assemblies are shown to the entire school, and they don't make a distinction between the authority of adults and the differences compared to children.
Yes, the schools are whacked out. The teachers discipline very little today, as they are in fear of losing their jobs. If you place a child in the corner, even if they're very disruptive and have had several warnings, the school may come after you. If you teach the children anything else that doesn't fit the PC Propaganda mold, a teacher could find his/herself placed on probation.
If it were up to me, I'd ask to keep your children out of these God-forsaken institutions, though some may be better than others.
