Each student has a hundred reasons not to sing this particular song; but in Deb Tully's classroom they belt it out. It's how they learn English and celebrate how far they have come.



Ms. Tully - or Miss, as her students often call her - has taught high school gym for nearly 30 years. She was about to retire when Ottawa's Rideau High School recruited her to teach English and math to newly-arrived refugee students.



They come from war zones and transit camps. They speak a dozen different languages. Many arrived not knowing how to write their own names; but, as their teacher learned, they do like to sing.



So each day, Deb Tully arrives at school armed with her guitar and tries to helps her students make sense of a new language and a new home. This year she did it with Louis Armstrong's "What A Wonderful World."



Producer Alisa Siegel brings us this story in her documentary "What a Wonderful World", which was first broadcast in June, 2014.
