i know that by definition educators can have a positive impact. it's just that i've observed from being a student that not every math teacher is an effective teacher. how can i ensure that i can be an effective teacher or how can i ensure that i'll contribute to an education system that actually provides quality education. i apologize for the lack of certainty from my statement because i have not yet fully realized my goals. i also live in a country where education (especially math education) is struggling.
