Research shows that students can have greater success in their studies when the information they learn is connected to key concepts. The Oxford Big Ideas History series provides a framework for developing students' historical knowledge, understanding and skills through inquiry questions and the use and interpretation of sources. The Australian Curriculum: History also identifies key inquiry questions or big ideas and core historical concepts and skills to be explored at each year level. Every chapter in the series mirrors this approach to ensure students develop deep learning of these big ideas, concepts and skills.
