Thorndike proposed three major laws of learning: 1) The law of effect states that behaviors followed by pleasant consequences will be repeated while unpleasant consequences will be avoided, meaning teaching must be interesting to encourage learning. 2) The law of exercise, also known as the law of use and disuse, suggests that connections are strengthened with practice but weakened without practice. 3) The law of readiness proposes that learning cannot occur unless the student is prepared and ready, requiring an aroused action tendency through preparatory adjustment or attitude.
