Reading is a cognitive process involving three components: decoding, comprehension, and retention. Decoding involves translating printed words to sounds. Comprehension refers to understanding a text through interaction between its words and outside knowledge. Retention is keeping information in short-term or long-term memory. There are two types of reading: intensive reading focuses on details, while extensive reading aims for general understanding. Reading is important for career, mental and creative development, and expanding vocabulary. Effective reading strategies include playing word games, reading aloud, engaging senses, and using marginal notes. The teacher's role is to diagnose skills, highlight demands, and provide instruction.
