Building pedagogical content knowledge (PCK)

What is PCK?

PCK embodies the integration of content and pedagogy into a comprehensive understanding of how specific content is structured, communicated, and adapted to cater to diverse learners’ interests and capabilities (Shulman, 1987). PCK encompasses two fundamental elements: knowledge of representations of subject matter and knowledge of specific student conceptions and learning challenges. For example, a chemistry educator’s PCK encompasses how they transform their content knowledge into forms and representations (e.g., chemical models) that are meaningful and comprehensible to students at a level that matches their development.

Lee Shulman introduced the concept of PCK in the mid-1980s to highlight a specialised form of professional knowledge that distinguishes educators from other professionals (Shulman, 1987). The notion of this specialised professional knowledge resonated well with educators and academics, leading to widespread exploration, adoption, and adaptation across various domains, especially in science and mathematics education.

Following Shulman's initial conception, numerous PCK models were developed over the years, generating differing orientations on PCK definitions and scope. Different PCK models used by researchers vary in their inclusion of knowledge domains. The most common knowledge domains (with definitions) that contribute to a teacher’s PCK are shown below (Sarkar et al., 2024; Chan and Hume, 2019).

So, PCK goes beyond mere subject matter expertise or general pedagogical skills. It involves a deep understanding of how to structure and deliver content in a way that makes it comprehensible and engaging for students (Berry et al., 2016). It considers the personal and contextual aspects of teaching and student learning, such as teacher beliefs, teaching orientation, learning environment, student beliefs, prior knowledge (with any misconceptions), and learning challenges, all of which significantly impact the teaching and learning process (Carlson et al., 2019; Hume & Berry, 2011). Effective integration of these knowledge domains requires teachers to adapt their teaching strategies to the specific content they are teaching, making PCK a nuanced and context-dependent form of knowledge (Shulman, 1987).

Importantly, PCK comprises a deep understanding of your students. What motivates them? Where do they face difficulties? To create a positive learning experience, you need to identify and address any misconceptions they bring to the classroom. These misconceptions, often deeply ingrained and complex, can shape how students perceive and interact with the world. Simply presenting accurate information may not be enough to change these misconceptions. You need to use active learning strategies that engage students in grappling with the concepts and reflecting on their understanding. Help them see how their misconceptions might be hindering their learning and guide them towards recognising and overcoming these barriers.

The recently developed Refined Consensus Model (RCM) describes PCK as the complex layers of knowledge and experiences that guide educators' professional practice to influence student learning (Carlson et al., 2019). This model identifies three distinct realms of PCK: (a) collective PCK, (b) personal PCK, and (c) enacted PCK.

Personal PCK

An educator’s unique and specialised knowledge for planning and teaching a particular topic.

Enacted PCK

Knowledge and actions of an educator within a specific teaching moment or situation.

Collective PCK

The accumulated knowledge that is widely agreed upon and formed through research and/or collective expert wisdom of practice related to the teaching of specific topics to specific groups of learners.

It is important to remember that PCK is not a fixed body of knowledge but is dynamic, developed and refined by educators over time, based on their experiences of teaching specific topics and through reflecting on their own teaching practice (van Driel & Berry, 2019).

Pause and reflect

  • How do you consider students’ prior understanding (including misunderstanding/difficulties) about any particular content when you teach that content?
  • Do you think different kinds of content ideas require different pedagogical approaches? Why/why not?
