Microsoft OneNote 2007 is a very powerful program that can be used for electronic delivery of chemistry lectures. Its features make it much more versatile than PowerPoint. Documents can be organized in a structured manner, and annotations can be easily added. Links to Web sites can be included and accessed on the fly. Clippings from external programs can be inserted with ease. A calculator feature allows mathematical expressions to be built and evaluated in real-time, right inside the document. When used with a tablet PC and a stylus, this system can be effective in teaching chemistry, eliminating the need for blackboards, whiteboards, or other presentation software. The ability to write and draw chemical symbols and to perform numerical calculations "live" in front of the classroom makes this type of technology ideal for any level chemistry course, although it is particularly helpful for first- and second-year undergraduate courses.
