Interestingly (well, to me, anyway), I used to live in Tennessee, now live in Connecticut, and used to teach, too. (I taught college-level chemistry and physics for seven years at a military academy prep school.)
I absolutely loved teaching. It was probably the best job I’ve ever had, and I was good at it, too. I received two awards for “Science Instructor of the Year,” and one for overall “Instructor of the Year.”
However, I ultimately decided to not make teaching a career after I got out of the military. My reasons included:[ol]
[li]Teachers aren’t paid very well, and are not typically rewarded for performance. Promotions and retention are dominated by seniority. (Like many other professions traditionally the province of women [including nursing], salaries have lagged those of professions requiring comparable training, either because women traditionally accepted lower pay or because administrators decided that teachers didn’t “deserve” any higher pay because they supposedly were not the sole earner in the household.)[/li][li]Around here, at the end of the school year, the teachers with the least seniority routinely get pink slips. They then spend months over the summer wondering if their contracts will be renewed.[/li][li]Teachers are not particularly respected, not by students, not by their parents, and not by administrators. It’s amazing to me how many people think that anybody can teach, much less teach well.[/li][li]The method of training new teachers is a mess. Prospective teachers get far too little subject-matter training, and far too much pedagogical theory backed up by little or no research indicating that the latest teaching fad actually improves teaching.[/li][li]The whole concept of tenure is an abomination, a concept that has no place outside of a research institution, yet it hangs on to keep long-serving poor performers in place.[/ol][/li]
To the point of the OP, though. Schools are funded by local and state governments, and local and state revenues are in the toilet lately. Therefore education budgets are cut, so the least-senior teachers get laid off, new teachers don’t get hired, and class sizes increase. In just a few districts across the country (including Washington, D.C.), administrators are actually making the effort to lay off the poorest performers instead of the ones with the least seniority, so there is hope, I guess.
I didn’t mean for this post to be so much of a rant–please accept my apologies. I will say that the job market is rough right now, particularly in the public sector, but things will turn around eventually.
I second the advice that others have made regarding substitute teaching. Also, have you considered teaching at a private or charter school?
