I was a teacher for 7 years. Elementary ed major. I dated a lot of teachers. Married one.
If she's like 99% of elementary school teachers, she is looking for CONSISTENCY. She wants a guy who looks good, but won't cheat. She absoltely does NOT want to get played, dumped, divorced, etc.
She loves kids - she is 27 so her body's clock is saying she's probably ready for babies of her own.
You need to present yourself as intelligent, stable, clean, professional - someone who won't embarass her at a PTA meeting with a prison tat, dipping tobacco, concealing a weapon, looking at the slutty young teachers, or playing the fool. You sound a little timid, but that might work well for you here.
Keep us posted on your progress. She's probably a little run off because you don't have a car. Impress her with your plans for the future, the path you plan to take, etc. I was a teacher earning my masters, teaching night school, and running the schools' computer lab. I drove a piece o shit car and lived in a trailer - and I did very well becuase they saw future potential with me.
Good luck brah.
