Let me explain who I am before I answer your question. I hold a California Teaching Credential, authorization to teach art K- 12 and have been trained in Reading Recovery. I have taught for eleven years, mostly in First grade but also have experience in Third and Kindergarten. I have also been chosen as a Master Teacher in Language Arts in three districts and have had a student teacher in my room. I love teaching and it is what I do best.
I am currently a Stay at home mom. I will probably return to the classroom because of my experience and expertise I am hired easily. But, do I want to return? It's a difficult and demanding job. It is only for those who can think quickly on their feet and are willing to change and grow. I am not sure that it will work with my other demanding 'job', a mother of three children.
Student teaching is difficult because it is like learning to ride a bike. You are learning to coordinate all of your muscles and balance to direct the bike to go the way you desire. Eventually, it does get easier because some of the tasks become rote.
'Regular' teaching is certainly not easy either. What makes this a challenge is vastly different from student teaching. Your husband will have very strong opinions about what are best teaching techniques. These opinions will be made because of his own childrens' experiences or training he has been through. Some years, these skills will be considered in favor and other years, he will be asked to not use them, even when he knows certain students need them.
There will be never enough resources either in the form of new textbooks, desk, paper, or patience. This will challenge him more than you can imagine because it will seem ridiculous that though we live in the United States we can't provide the very basic resources for teachers to use. This fact will change dramatically depending on where he is hired. The disparity between the wealthy and the poor will never be so highlighted. He will want to work in a wealthy district despite the overbearing parents. And he will want to work there for exactly that reason. Those overbearing parents will provide the resources for their teachers and will, for the most part, send children who are ready to learn and have a well rounded background.
So yes, he will survive through his student teaching but I am not going to lie to you, the statistics are pretty grim for him making it past five years as a teacher. I think it is as high as 1 in five give up before that fifth year. What makes the difference? A true love or calling to teach despite the hardships. Great mentors that support him and can lend him help when he needs it. A district that doesn't change their programs and textbooks so often that your head spins.
I wish him good luck. I don't mean to sound so disspirited. It is a callling; and it is as hard as a tech job without the pay.
