Presentation Manager And Web2.0: Understanding Online Presentations
The problem of the effectiveness of academic lessons and meeting presentations made available on the web through the usage of software and platforms like Slideshare and Moodle is fundamental for the development of new teaching technologies. We compared the recall and perceived cognitive effort in three groups of undergraduate students following the same lesson in different formats: audio, text, audio plus text. Students that acquired the contents of the lesson using both the auditory and the visual modalities substantially improved their recall performances relative to students that used either audio alone or text alone. Textual format complements (not hinders) auditory information by providing a frame of reference that can be utilized to identify basic contents. Double modality, allowing for the integration of information, is an extended presentation format.
