练习, 训练
a way of instruction through repetition and a lot of practice
A drill is a structured practice activity designed to reinforce specific skills or concepts through repetition. In educational contexts, drills often involve repetitive exercises aimed at improving proficiency in a particular area, such as mathematics, language learning, or physical skills. For example, language drills may focus on vocabulary, grammar, or pronunciation, allowing learners to practice and internalize new material. Drills can be conducted individually or in groups and may take various forms, including written exercises, oral practice, or physical activities. While drills can be effective for skill reinforcement, they are often most beneficial when combined with other teaching methods that promote understanding and application of knowledge.
