Critical thinking is an important skill that helps process information by objectively analyzing and evaluating issues. It involves questioning information to reach a deeper understanding, and moving from lower to higher levels of thinking. Critical thinking skills like reasoning, evaluating, problem solving, and analyzing need to be developed. It is an active process of gathering information from multiple perspectives, asking who, what, when, where, and how questions, and making informed judgments or decisions rather than passively accepting all information at face value.
