In recent years, there has been increasing attention devoted to the need for individuals to be lifelong learners. The United Nations Educational, Scientific and Cultural Organization (UNESCO) identified the formation of lifelong learners as one of the most desired outcomes of education. Lifelong learning entails understanding what counts as knowledge in a particular field, as well as the methods and criteria that are used to construct it. Honing these skills is what allows individuals to evaluate new information and progress as learners throughout the lifespan. Thus, the role of educators today is to help students acquire new knowledge and assist them in developing their thoughts about the nature of knowledge and the process of knowing.
