GoClass is a free iPad application for creating short lessons and delivering them to your students. The lessons can include annotated images, free hand sketches, text, and video. GoClass gives teachers tools for creating class rosters that they can use to keep track of which students are using the lessons when. Teachers also have the option to ask questions and poll their students. After the students' response have been gathered teachers can project those responses without showing individual student's names. The image below, from GoClass, illustrates how a teacher might use the app with students.
