Pick a student at random just by giving your device a shake or tapping the screen -- but that's just the beginning. Stick Pick suggests question starters for learners at different levels and also records how well students respond during classroom discussions. If a student is consistently scoring near the top or bottom, simply change the level so students aren't bored or frustrated. Depending on students' levels of English proficiency, they might be asked simple yes-or-no questions or to elaborate in longer sentences.
