Flashcard Machine is a website that allows students to study flashcards on their iPod using the iStudyToGo application. The site helps teachers differentiate instruction for students with different learning profiles, which include their preferred learning style, group size, and study environment. Teachers can use flashcard resources on the site to meet the varied needs of visual, auditory, tactile, and kinesthetic learners who may study alone, in small groups, or in large groups in either open or quiet spaces.
