A Review of Concepts, Theories & Empirical Evidence of Pedagogical Content Knowledge(PCK)

Abstract 
Pedagogical Content Knowledge (PCK) 
continues to be an important construct in 
understanding how effective teachers are 
and how well their students achieve. Based 
on the work of Shulman, PCK combines 
content knowledge (what is taught) and 
pedagogical knowledge (how it is taught) 
and contextual knowledge of learners and 
environments in which they learn. This 
review incorporates conceptual, theoretical, 
and empirical views of PCK, emphasizing 
the multidimensionality of PCK and its 
contribution to quality instruction. The paper 
initially discusses the difference and relation 
between content knowledge and pedagogical 
knowledge and their combination as PCK. It 
then examines key elements of PCK 
including knowledge of learner's 
misconceptions, instructional strategies, 
curriculum design and assessment practices. 
The constructivist theory serves as the 
guiding framework which emphasizes the 
learning as an active process, contextual and 
social where teachers act as facilitators of 
knowledge construction. Empirical studies 
reviewed show that teachers with higher 
levels of PCK have a positive impact on 
student's academic achievement in

disciplines and also highlight the need for 
specific teacher training and professional 
development. The local and international 
contexts also provide evidence that PCK is 
dynamic and develops as an experience, 
reflective practice, and a process of constant 
learning. The paper ends by saying that the 
need to enhance the PCK of teachers is 
essential in order to enhance learning 
outcomes and to overcome misconceptions 
and stimulate student motivation, especially 
in science and mathematics education. This 
review therefore offers valuable insights for 
teacher education programs, policymakers 
and researchers who are concerned with 
improving the quality of instruction by 
building the professional knowledge base of 
teachers.
