I was grading spelling tests at 4th grade today, and I was deeply disturbed by several of the bad results. I mean, my child only got 10 out of 20, so it was apparently a list of words the teacher was counting on the parents to make the kids study. But it was so much worse than than.
I hope the explanation is that there was a chain of 5 kids copying off each other, each one doing it a little less perfectly until you got to a point where only the first letter and general length of the word was right. It's kind of devastating to think someone can get to 4th grade and spell so poorly. I would guess 12/20 was about average, with a few outliers on either end. There were children who got 1 and 0 on this test. The words I can remember were:
Adjustment
idly (the most correctly spelled word)
lonely
solvable (I would have missed this)
preoccupied
envious
insist
decision
motorcycle
rearrange (probably the most misspelled word)
Treasure Island (my kid was one of a few kids who missed this because it was written on the wall... sigh)
latitude (I might have missed this)
longitude
courageous
And then there were three bonus words: immense, treacherous, and mischief. I'm not sure what made them bonus, but almost no one got them.
I couldn't really detect a theme to this spelling list, and maybe there wasn't one. Maybe my memory of how well one should be spelling in 4th grade is distorted. I graded the math papers and the performance was a lot closer to what I might expect. When I gave them back to the teacher I mentioned they were better than the spelling tests and the teacher said she didn't know why the kids were having such a hard time, worse than last year. I don't know. Maybe it's some unintended consequence of core curriculum education, whatever the heck that means.
I do recall that we had a separate textbook for spelling in 4th grade. I'll have to ask my child about that.
