Social Networking by and for School Librarians
inClass is a fantastic free iPad app that students can use to take and keep track of the notes they record in all of their courses. inClass allows students to organize notebooks for each of their courses. Within each notebook students can include typed notes, audio notes, video notes, and pictures. The ability to store those four types of notes makes inClass a great app for students to use in a science lab where they might want to have a little video clip of an experiment along with their own typed notes about the lab experiment.
