The Australian Council for Educational Research (ACER) has reviewed the extensive literature on creative thinking and developed both a definition and a framework that synthesise and harmonise existing theory and research on creative thinking. This framework has been developed to address the challenges associated with teaching and assessing creative thinking. It outlines creative thinking processes along prescribed strands and aspects informed by a sound evidentiary basis. The aspects contained within the framework are designed to provide foci for teaching and the basis of assessment. ACER’s creative thinking framework identifies key factors that underpin the development of creative thinking with a focus on observable skills and teachable creative thinking strategies. A main aim of this framework is to support the development of standardised assessments that can be delivered in the classroom and in doing so, support teachers in developing and evaluating students’ creative thinking skills.
