Professionals who dispense information (Teachers, Doctors,
  Lawyers come to mind first) tend to HATE the Internet in
  general, except those sites which they approve of, because of
  lack of control.

  In short, it's competition. Children saying, "Wikipedia said"
  goes against what the teacher's textbook says. The teacher works
  with the textbooks (or if they care about what they teach,
  themselves) for the curriculum and Wikipedia does not follow
  academic curriculum. [I could rant about the assumptions of
  19th-21st century education but then there'd be a Tome so I have
  to be care when I get started on the subject tongue emoticon The
  Progressivist movement of Dewey was very fruitful. That was a
  child-centered, child-driven philosophy that was supported by
  the system. The Internet as it functions without adult
  supervision functions similarly by providing an abundance of
  resources, in a sense.

  But Dewey's ideals were abandoned around 1940 as the country
  geared up to enter WWII and hasn't looked back since, the only
  leftover bits of Dewey are among School Librarians, oddly
  enough, unless they're encumbered by local figures to remove
  certain books. Oh well. I can't fix school. I have to tell
  myself that whenever I start on the subject. You're both right
  in a sense that it's not _entirely_ credible, but neither are
  the very textbooks the teachers are teaching from / the kids are
  learning from.

  So in that sense you're also both mistaken.

  Putting a black hat on Wikipedia and a white hat on textbooks
  doesn't solve the issue of thinking critically.

  Example: In 6th grade, there were pictures of cavemen in my
  history book with blond hair and blue eyes. This was 1983 - not
  that long ago. The methodologies used then in school are the
  same as today - Bell Curves and such, statistical methodologies
  and whatnot for grading. Even Common Core isn't _that_
  fundamental of a change [although I have some nit-picks about
  it]

  Ok, not the best example. Still, critical thinking needs to be
  applied _across the board_. Otherwise it is simply "This is
  authority. Period. This is not authority. Period." That's not
  critical thinking. That's dogma. My apologies and you're
  correct. Within the school system itself, that is correct.
  Surviving school is an important skill for children to learn at
  a young age and knowing how it works is important so for that, I
  applaud the 2nd grade teacher.

  It does not help them as adults but it _does_ help them while
  they go through a school system that has its own special ways
  about it. Socio-historical critical readings are, unfortunately,
  out of fashion at the moment. "Fact" and "Authority" are in
  fashion, wrapped under the umbrella of a
  critical-thinking-that-*isn't*.

  I admire the "ideals" of Common Core but it's unfortunately
  going to be a fad, like all of the fads that came before that
  each of us got stuck with in our schools growing up, that
  they'll abandon in 10-12 years for something new. Lots of
  hoopla, lots of money, then all the criticisms and dismantling
  of it for the "next new thing to replace "Grit" with.

  Ok. I almost launched into my Common Core rant. I'm not going to
  do it....

  Your daughter has to survive school.

  For school survival, knowing what _they_ find acceptable and
  unacceptable is important.

  But _YOU_ are in a place to let her know that, "This is how
  SCHOOL does things. It doesn't mean it reflects reality."

  I had to have the same type of discussion with my nephew when he
  was 8 yrs old and complaining about the way they taught math.
  [it's gotten worse now that he's in 4th grade].

  I explained that Yes, the school system you're in is flawed just
  like you think it is. But if you learn to give the teacher what
  they EXPECT from you, you'll survive. You can get good grades
  while still thinking for yourself.

  He does very well in math - I told him how to "show his work"
  while still calculating in his head at the same time.
  Socio-historical critical readings are, unfortunately, out of
  fashion at the moment. "Fact" and "Authority" are in fashion,
  wrapped under the umbrella of a critical-thinking-that-*isn't*.

  I've been ranting about the way schools do things since I was at
  least in 4th grade that I remember.

  I wrote letters to the school newspaper - even one to the local
  paper when I was 12-14... I'm 43 now and it *still* bothers me
  that nothing's changed. Can't be fixed though. Just survived.
  Thriving is possible too. I wish it wasn't that way... but it's
  too big to change, too much invested in too many places. Unless
  you want to form parental education groups, there's not much you
  can do for them. But you *can* do something to help your
  daughter. One well rounded person is far better than 10,000
  biased people who speak with a singular voice, imo.

  But I'm an individualist... a product of my upbringing which
  included my mother, who was supportive of my odd way of looking
  at the world that she didn't understand herself but supported.
  My 10 yr old nephew just popped out here, talking about Five
  Nights at Freddy's 3 and where he's gotten in the game.

  Children's culture [entertainment, friends] have greater
  influence on their way of thinking than school does anyway,
  [1]Erek Tinker - so try not to stress too much about it. You'll
  learn more about "how kids think" by understanding Five nights
  at Freddy's or Minecraft than you will what they learn at
  school, unless they're obsessed by school.

  Whatever the obsession is, that's the real curriculum. But I'm
  biased as I tend towards a Dewey / John Holt-Unschooling / JS
  Neill Summerhill outlook on things. I believe children learn far
  more math and algebra, war and compassion, by a Pokemon
  obsession than by learning the arcane 17th century short-hand
  for mathematics. Myself, I learned more math by getting a Tandy
  Color Computer 2 at age 11 and teaching myself to program in
  BASIC than I ever learned in school.
