Computer Assisted Instruction (CAI) refers to the use of computers in educational settings for teaching and self-learning through various methods such as drill and practice, tutorials, simulations, games, and problem-solving. CAI offers advantages like one-to-one interaction, immediate feedback, and self-paced learning, but also presents limitations including potential information overload, high costs, and mechanical learning. The document concludes with a reference section and a summary assignment for further exploration of CAI.
