We have just put online a video and PowerPoint slides (in pdf format) of an introductory demo of the new web-interface to the Michigan Corpus of Academic Spoken English (MICASE). The demo was given by Stefanie Wulff and myself as an in-house presentation at the UM English Language Institute in December 2007. We explain how MICASE online can be accessed (i.e. how the corpus can be searched and browsed and how the search/browse results can be analysed and saved) and give examples of how MICASE online output can be used in the creation of teaching and testing materials. The video and slides of the presentation we used are both linked from the MICASE index website at http://lw.lsa.umich.edu/eli/micase/index.htm. The direct link to the video is http://lw.lsa.umich.edu/eli/lecture/micase/video.html. The presentation slides are available at http://lw.lsa.umich.edu/eli/micase/Demo.pdf (the video takes a minute or two to load and appears only in a small window, but the resolution and sound quality are quite good, and you can look at the slides alongside if not everything is legible on the screen).
