A teacher is a person who gives instruction or lesson on a subject to human beings or animals. A teacher (also called a school teacher) is a person who provides education for students. MacLean and Mohr (2009) explained that the term teachers are subjective insiders involved in classroom instruction as they go about their daily routines or instructing students, grading papers, taking attendance, evaluating their performances as well as looking at the curriculum. Teachers raise questions about what they think and observe about their teaching and their student’s learning. They collect students work in order to evaluate performance, but they also see students work as data analyze in order to examine the teaching and learning that produced it”.
