Critical reading involves analyzing a text to understand its meaning and purpose beyond just comprehending the literal words. It requires reflecting on what the text says and does by making judgments about logical ideas and connections. Simple reading aims to understand the basic definition and central idea of a text, while critical reading has the additional goals of understanding an author's purpose, tone, biases, and inferring deeper meaning. Critical thinking builds on critical reading by applying complex thought processes like identifying main ideas, drawing conclusions, comparing/contrasting, and determining facts versus opinions to make reasoned judgments and solve problems effectively.
