Teachers have the very important responsibility of shaping the lives of young, impressionable children. With this responsibility comes great pride and joy. Therefore all teachers should strive for what can be considered to be a "good teacher."
A good teacher can be defined as someone who always pushes students to want to do their best while at the same time trying to make learning interesting as well as creative. A positive or negative influence from a teacher early on in life can have a great effect on the life of a child. 
Teachers, especially at the elementary level, must be very creative with their teaching styles. Not every child learns the same way, nor are they interested in the same things. It is difficult to keep the attention of 15-20 children under the age of ten. Classroom setup and design is a good way to get and keep the attention of students.
