This a great tool.
Stick Pick is an iPhone / iPod Touch / iPad “teacher tool” application that allows you to randomly (or intentionally) draw a student’s name from an on-screen can of popsicle sticks -- but that’s just the beginning. You determine the mode and level of difficulty for each learner, and then, every time that student’s stick is drawn, you’ll be shown over a dozen Bloom’s-style question stems -- uniquely tied to your learner’s individual ability level!
Stick Pick offers over 140 question stems, organized by cognitive and linguistic level, so teachers can quickly and conveniently ask the right question to the right learner at just the right time. With Stick Pick teachers promote higher order thinking skills, English language development, and equity among learners of all levels.
