Today I had to illustrate for my students the concept of “winging it.” After installing PowerPoint 2007 on my computer and slaving for 5 or 6 hours over my class presentation, this morning I found that the new version of the software doesn’t work on the classroom computer system. In my first class I wrote “Major Crisis” on the board, then proceeded to write by hand – mostly from memory – my entire lesson on the blackboard. That’s twice, once for each class.
I did pretty well, considering, but my writing hand was tired. I listed the attributes of a good presentation outline, then gave a sample presentation on global warming; I even drew a presentable diagram in colored chalk of the earth’s atmosphere and the role of C02 in causing the greenhouse effect. I remained cool, calm, and collected throughout. Fortunately, the film clip from Al Gore’s An Inconvenient Truth worked just fine, although the version I used managed to lose its Chinese subtitles.
Later, I figured out how to save my PowerPoint presentation to the older version, so it’s now usable in all circumstances.
Then, that afternoon, there was the earthquake….
