Ra Ra, Ha Ha Ha
This instructor knew how to get their pupils’ attention. Young people, especially those in their teens, are interested in popular culture and music. “Lady Gaga” is still a song that most individuals recall.
This instructor was able to mimic a portion of the song’s hook by arranging the components so that they make the same sounds. We may infer that this teacher’s spirit loved this surprise. It’s always wonderful when teachers can divert attention from kids by drawing on things they are interested in.
