, QUESTION 1
1.1 Big Ideas of Science
Pedagogy they are linked to
The ―big ideas of science‖ are linked to constructivist pedagogy, where teaching
focuses on helping learners build deep understanding of key scientific concepts
rather than memorising isolated facts. This pedagogy encourages inquiry, critical
thinking, and connecting ideas across different areas of science.
Definition of the term
The ―big ideas of science‖ refer to the core concepts, principles, and
explanations that underpin our understanding of the natural world. They are
fundamental ideas that provide learners with a coherent framework for making sense
of scientific knowledge. Instead of covering endless small details, big ideas highlight
the essential understandings that can be applied across many contexts. They aim to
ensure that learners grasp the explanatory power of science and can use it to
interpret everyday phenomena.
Where they come from
The concept of ―big ideas of science‖ comes from science education research and
curriculum reform movements that identified the need for learners to develop long-
term, transferable understanding of science. International projects such as Trends in
International Mathematics and Science Study (TIMSS) and reports by organisations
like the Association for Science Education (ASE) and the Royal Society shaped
the framework. In South Africa, it also aligns with curriculum reforms that emphasise
critical outcomes, problem solving, and scientific literacy for all learners.
