Is teacher training course is value ?
A teacher training course by itself may be worthless. I suppose that if you wanted to explore being a a teacher, it might have some value to you. After all, all kinds of education has value. You would need a BA degree in education before you could become a teacher. You do not have to love children to be a good teacher, but you have to know methods, curriculum, other subject matter, and be comfortable with being with children, tweens, or teens. I’d say a teacher training course may be helpful, but if you are not already committed to teaching, then it might be good to take the course and see what value it might have for you.
