I have been following these stories for the past 7 years. What I don't seem to understand is why this problem is not being fixed the answer is so obvious that is doesn't take a college degree to see it. First of all you can't put unqualified people in classroom to teach. That is mistake one, however, I understand they need warm bodies and feel they have no choice...but they do have a choice. Fix the problem. Every article has cited the same issues which all comes back to one core problem. Teacher pay. Fix it. Pay teachers enough to live. Adjust salary for the cost of living. Then you will get enough certified teachers to fix the problem. It is better to have a certified teacher in the classroom than just a warm body. It doesn't matter if your teachers are home grown if they still can't afford to live on a teacher salary, then you still have the same problem. Fixing the salary issue will fix the other issues too.
