I taught three kids to read using phonics only, and it was the simplest thing in the world. Start them out at about three years old learning the sound values, and don’t worry about them catching on ... at some point between age five and six they will start reading anything and everything, just like magic.
Yeah ... teaching a child to twist screws into wood with a screwdriver is also simple. Teaching a child to install screws with a hammer is a bit more difficult ...
Written language is a tool; it's best to use it as designed. English is a phonetic language by design.
