Yes, I have coached students in speech contest and lyrics contest. But I don't have experience for traning them for English drama contest. However, there some evaluation similarities that theste contest shares, like pronunciation, body gesture, fluency and stage performance. At first, I'll divide the students into groups , ask them to prepare for the genre and read to each other. Then, we will spend some time in pronunciation and correct their pronunciation group by group. Then students have to do some brain-storming about how they can perform this sentence, like gestures and eyesight. After making them into groups in preparing. Some of the students have to take in charge in sounding, texts, and stage materials. According to students' personality, thery are also divided into groups to share some works.
