いい加減な発音で長い文章を暗唱させるな。きちんとした発音で一つの文を read, look up, and say させろ。それができたら次の文を read, look up, and say させろ。生徒の時間とエネルギーを無駄なことに使わせるな。
DO NOT make your students recite a passage with katakana pronunciation. DO make them read, look up, and say one sentence. When they succeed, make them do another sentence in the same way. DO NOT waste your students' time and energy by forcing them to do something useless.
