TPACK in Secondary Science
TPACK
In the TPACK model, each of the three circles—Technological Knowledge (TK), Pedagogical Knowledge (PK), and Content Knowledge (CK)—represents a distinct area of expertise that teachers need to master. The “place to be” is right in the middle, where all three circles overlap. This overlapping region is sometimes called the “sweet spot” and is usually labelled “TPACK.”
Here’s why that centre is so important:
1. Balanced Focus
• If you focus solely on Content Knowledge, you might become an expert in physics or biology but lack the methods or tools to convey these ideas effectively to pupils.
• If you focus mainly on Pedagogical Knowledge, you may have brilliant lesson structures or engagement strategies but be less confident in subject accuracy or in-depth understanding.
• If you rely heavily on Technological Knowledge, you might use plenty of digital tools but risk implementing them in ways that aren’t aligned with pedagogy or subject content.
2. Synergy of All Three
• In the centre, you’re blending subject expertise (CK), effective teaching methods (PK), and the right technology (TK) all at once. It means you’re choosing digital resources (TK) that truly enhance pupils’ understanding (PK) of your specific science content (CK).
• This synergy helps ensure that technology isn’t just a novelty, that pedagogy is supported by the best tools, and that the science content is both accurate and engaging.
3. Practical Relevance
• When you operate from that intersection, your lessons become more relevant and interactive. For example, if you’re teaching Newton’s Laws (CK), you might design an inquiry-based experiment (PK) and use a simulation or data-logging sensors (TK) to make the learning hands-on and data-driven.
• Pupils see theory (CK) in action, apply scientific methods (PK), and gain digital competencies (TK)—all in one cohesive experience.
4. Learner-Centred Outcomes
• Teaching from the TPACK centre makes it easier to meet diverse learner needs. You can quickly adapt or personalise content using technology, give real-time feedback, and engage pupils with varied teaching strategies.
• By thoughtfully merging these three knowledge areas, you create lessons that are multidimensional and accessible to a wide range of learners.
In short, the centre of the TPACK diagram is where you integrate all three forms of knowledge so they complement one another, resulting in teaching and learning experiences that are authentic, engaging, and academically sound.
What might this look like?
This is an overview of the three knowledge domains (CK, PK, TK) for secondary science, each enriched with AI. Think of it as a quick reference to see how all the extended frameworks fit together.
Content Knowledge (CK)
Emphasises the science content that pupils must master—covering facts, concepts, methods, and the nature of scientific inquiry. Presented via four types of scientific understanding:

When these three intersect—supported by AI at each step—teachers can design engaging, accurate, and 21st-century science lessons, empowering pupils to think and act like real scientists.
CK Content Knowledge
1. CONTENT KNOWLEDGE (CK) FOR SECONDARY SCIENCE
This section uses the four types of scientific understanding—Perceptual, Conceptual, Procedural, and Epistemic—to describe the content you want pupils to master in secondary science. It includes extended definitions, AI enhancements, and activities.
Four Types of Scientific Understanding
1. Perceptual Understanding: is grounded in direct observation and sensory engagement, allowing pupils to form initial mental models from tangible or visible phenomena.
2. Conceptual Understanding: focuses on why scientific phenomena occur and how concepts interrelate. It moves beyond seeing something happen to explaining it with theories or models.
3. Procedural Understanding: teaches how to do science, including designing experiments, collecting data, and interpreting results systematically.
4. Epistemic Understanding: deals with how scientific knowledge is formed, tested, and refined—encouraging pupils to see science as a dynamic, evidence-based process.
A. Perceptual Understanding
• Extended Definition
• Involves firsthand or virtual observation of scientific events (e.g., seeing a balloon deflate, exploring an AR model of the solar system).
• Provides a concrete basis for later, more abstract concepts (like forces, cells, or chemical bonds).
• Supported by interactive technology (e.g., VR field trips, slow-motion video analysis).
• Three Examples
1. Observing Balloon Rockets: Pupils watch how releasing air propels a balloon, gaining an intuitive grasp of Newton’s Third Law.
2. Mixing Hot and Cold Water: Pupils feel the temperature change, noting condensation or heat flow—foundational for thermodynamics.
3. Tracking Seed Growth: Visually following how seeds germinate under different conditions (light, temperature) sets the stage for understanding photosynthesis and plant biology.
• AI Enhancements
• AR/VR Tools (e.g., Merge Cube, Expeditions) to explore hidden forces or internal structures in real time.
• AI-Powered Video Analysis (e.g., Tracker, Hudl Technique) for slow-motion review of motion or physical changes.
B. Conceptual Understanding
Definition
• Emphasises relationships between concepts (cause-effect, structure-function).
• Grows through discussions, models, and abstract reasoning.
• Builds on pupils’ prior experiences, shaping a cohesive mental framework of science ideas.
• Three Examples
1. Explaining Buoyancy: Understanding Archimedes’ principle—why objects float or sink based on displacement and density.
2. Thermal Conductivity: Linking why metal feels colder than wood (heat transfer rates) to conduction principles.
3. Newton’s Laws & Seatbelts: Recognising how inertia, force, and acceleration apply to everyday safety devices.
• AI Enhancements
