Speech on the Internet: Active Use of Online Digital Audio in the Classroom
Hearing the spoken word expands our understanding of a speaker’s intent, emotion and meaning. As with any primary source, however, these materials do not literally “speak” for themselves; they require interpretation, analysis, and manipulation. The recent emergence of online digital audio archives has brought educators a major step closer to bringing original, reusable spoken word sources into the classroom. As part of an NSF grant, we have recently released a beta version of MediaMatrix ¬ an online tool that allows users to find, segment, annotate and organize streaming media found on the Internet. Media Matrix works within a web browser, allowing users to segment sound (isolate any size portion of a whole clip) and add their own annotations. Users can organize their thoughts on the portal page and create multimedia presentations. Media Matrix allows teachers to gather and present media for the classroom, students to integrate media into their assignments, and scholars to perform the kinds of tasks performed in traditional libraries with analog objects (gather resources, take notes, publish findings).
This paper will place MediaMatrix in a context of use and development, and thus will: (a) identify key technologies that scholars and students can use to manipulate online digital audio; (b) review what is known about effective use of online audio in the classroom; and (c) offer some guidelines for maximizing the effectiveness of online audio in educational applications.
