Mobile Learning Bites
Mobile learning brings together the limitations of small screen display with the understanding of how today’s users consume information, to publish learning material in the form of “knowledge nuggets” or “learning bites”.

Examples of this type of microlearning include reading a paragraph of text, listening to a podcast or educational video-clip, viewing a flashcard, memorizing a word, vocabulary, definition or formula, selecting an answer to a question, answering questions in quizzes etc.
