     Nowadays, being a teacher is a difficult yet rewarding job. Not everyone is suited for teaching. Aside

from having love for working with children, teaching is a career like no other.

    An effective teacher is not only the master of his/her subject area, but also an educator with the strong

emotional backbone. Daily, the teacher communicates with students from different backgrounds, with

different learning skills, and with different emotions.

    The teacher will set high expectations of all students and never give up the underachievers. The teacher will always be available to students whether it's before classes begin or after school. He/She will also have additional work for students need extra assistance in learning the subject.

    An effective teacher will contrast his/her lesson with the material so that students will look at the

material in various ways. This will ensure that students remain on task during the entire class session.

Being asked openended questions, students will remain interested and not be bored. Difficult as this may

sound, it can be achieved.

    The teacher will always be an enthusiastic, organized, and caring individual, and will make learning fun. He/She will not simply write the assignment on the board，and tell students "There's your assignment.

Get to work!"  and proceed to sit at his/her desk for the remainder of the period. Instead, the teacher will

add games or use media in the learning process; in this way, students will crave (渴望) learning.

    Our children need support, guidance and proper instruction so that they will succeed in life, not only in

the career they choose, but also as the person they become.
