Teachers make subject-matter accessible to students by populareducationtips content knowledge. Pedagogical content knowledge has two broad areas of knowledge: teachers’ knowledge of students’ subject-matter pre-conceptions and teachers’ knowledge of teaching strategies. What Pedagogical content knowledge does is that, it links subject-matter content knowledge and the practice of teaching, making sure that discussions on content are appropriate and that, discussions focus on the content and help students to retain the content. The teacher’s job is to facilitate the learning of subject-matter by students.
The degree to which the teacher can assist students to learn depends on the subject-matter content knowledge the teacher possesses. Teachers who possess inaccurate information or comprehend the subject-matter in narrow ways, harm students by passing on the same false or shallow subject-matter knowledge to their students. The last of the three determinants of teacher quality is experience. Teachers who have served more years gain additional and more specific training by attending seminars, conferences and workshops and in-service training and so tend to understand their job better. They also might have met and solved many challenging situations in their classroom and therefore know exactly what to do in any situation.
The teacher conceives knowledge in such a way that it is narrow, or do not have accurate information relating to a particular subject-matter, he/she will pass on these same shallow or inaccurate information to students. This kind of teacher will hardly recognize the consistent pre-conceptions and challenge the misconceptions of students. Such a teacher can introduce misconceptions as he/she uses texts uncritically or inappropriately alter them. It is the teacher’s conception of knowledge that shapes the kind of questions he/she asks and the ideas he/she reinforces as well as the sorts of tasks the teacher designs.
Teachers’ subject-matter matter content knowledge must go beyond the specific topics of their curriculum. This is because the teacher does not only define concepts for students. Teachers explain to students why a particular concept or definition is acceptable, why learners must know it and how it relates to other concepts or definitions. This can be done properly if the teacher possesses a good understanding of the subject-matter. This type of understanding includes an understanding of the intellectual context and value of the subject-matter. The understanding of subject matter generally reinforces the teacher’s confidence in delivering lessons, thereby making him/her a good teacher.
Experience is one of the factors that account for variations in teacher salary, the world over (Hanushek and Rivkin, 2006). The fact that salary differences are based on the number of years the teacher has served, suggests that employers believe the teachers experience makes him/her a better teacher and such a teacher must be motivated to remain in the service. Though some studies like that Hanushek (2011) have suggested that the experience positively influences teacher quality only in the first few years, and that beyond five years, experience ceases to have positive impact on teacher efficacy, common sense tells us the one who has been doing something for a long time does better and with ease. Experience will therefore continue to pay, since, more experienced teachers have the propensity to know more about the subject-matter they teach, and think and behave appropriately in the classroom, and have much more positive attitudes toward their students.
Teachers who have spent more years of teaching, usually, feel self-assured in their skill to use instructional and assessment tools. These teachers are able to reach even the most difficult-to-reach students in their classrooms. They also have greater confidence in their capability to control the class and prevent incidence that might make the teaching and learning process difficult. Their experience makes them much more patient and tolerant than their counterpart with few years of experience (Wolters & Daugherty, 2007). Novice teachers progressively gain and develop teaching and classroom management skills
