Reminds me of this:
How a flawed idea is teaching millions of kids to be poor readers
She says sounds and letters just didn't make sense to her, and she doesn't remember anyone teaching her how to read. So she came up with her own strategies to get through text.
Strategy 1: Memorize as many words as possible. "Words were like pictures to me," she said. "I had a really good memory."
Strategy 2: Guess the words based on context. If she came across a word she didn't have in her visual memory bank, she'd look at the first letter and come up with a word that seemed to make sense. Reading was kind of like a game of 20 Questions: What word could this be?
Strategy 3: If all else failed, she'd skip the words she didn't know.
Most of the time, she could get the gist of what she was reading. But getting through text took forever. "I hated reading because it was taxing," she said. "I'd get through a chapter and my brain hurt by the end of it. I wasn't excited to learn."
No one knew how much she struggled, not even her parents. Her reading strategies were her "dirty little secrets."
Apparently, in the US, some teachers are not teaching the relationship between pronunciation and spelling, so some students come with these strategies (or rather, as flan pointed out, they actually teach the kids to do this).
