Go to any school you choose and speak with the English language teacher or with the superintendent. Ask him/her if there are students who do well in mathematics but are unable to read in English.
All schools have at least 10% of kids who leave school without being able to read. The question is to ask as to why this is the case.
Also ask as to how I dare say that I can teach Jill to study after one minute of interacting with her. All I did was talk to Jim and Jane for about 20 minutes and then for less than a minute asked Jill to read a few alphabets written on a sheet of paper. After the one minute with Jill I knew she was a shut down learner.
After my first lesson with Jill I have confidently confirmed that I can get Jill to read at grade level within 4 months. I leave you with these questions to ponder and ask yourself as to why kids are not taught in a way that they ought to be taught. Why kids are not taught in a way whereby the illiteracy level will be reduced drastically?
