If lesson materials could be recorded on cassette and video tapes, teachers could lend these out to the slower students to use at home. This would solve problems with pronunciation and enable such students to keep up with the rest of the class. Then they would not give up.
如果老師上課的教材能借製成錄音帶及錄影帶，讓學習較慢的同學借回家反覆練習，則可解決發音和進度問題，學生自然不至於放棄學習。
