The history of critical thinking is deep rooted. Often attributed in the Western cannon to Socrates, the “Foundation for Critical Thinking” also cite Thomas Aquinas, Francis Bacon and Immanuel Kant amongst others. In the context of 20th century education, they highlight the work of William Graham Sumner and John Dewey, stressing that the development of this line of thought is varied and shared. Today, it is central to many education systems across the world. Teaching and learning about critical thinking then, has become a primary objective for many educators and education programs, either as a skill embedded in a program or as a specific course in and of itself. Simultaneously, it has become a recurrent challenge, sometimes a polemic issue, and always a question open to interpretation for all involved: educational policymakers, universities, schools, teachers and even learners themselves.

Embedded within this history and current scenario is a failure to find an agreement on the roots and implications of critical thinking in the professional world and in the ‘professionalism’ expected of learners in the workplace. What it means in the learning experience and in the work context then, are both questions of debate. Despite such limitations on agreed definitions and roles, it has become an essential learning objective in the 21st century academy and an increasingly identified skill sought by employers. In the broader social context implied by the world of work then, critical thinking is now considered vital when we refer to the challenges society faces, whether they be in the realm of climate change or in the field of artificial intelligence. With technological advances strengthening human decision-making in different areas of life, it is arguably more important now than ever to be ‘critical’ in the way we think.

In this context, schools and higher education institutions have a unique position and role. We are responsible for reflecting on why and how to promote critical thinking: how and when to teach it; how and if to grade it, how and where to apply it to our students and, importantly, to ourselves and how we operate as educators.
