Stick Pick is an iOS app that allows teachers to differentiate instruction through questioning students at their appropriate readiness level. It allows teachers to create classes, add students, designate each student's assessment mode based on frameworks like Bloom's Taxonomy, and generate questions tailored to each student's level. Teachers can then "stick pick" to randomly call on students, track responses and scores, and export performance data to share with others. The app provides a more personalized form of differentiated instruction compared to previous techniques like popsicle sticks or cards.
