A former classmate of mine from 6th Form College (equivalent to final two years of high school) is now a professional writer and editor. He has produced a couple of short notes on good writing and editing from a seminar he gives. They are only 9 and 2 pages long respectively. I found them very useful. To whet your appetite here one of his examples:

"In the final analysis, it can clearly be seen that appropriate utilisation of participatory techniques in the project planning phase is likely to result in more successful outcomes vis-a-vis community acceptance in the project implementation phase."

becomes

"Communities are more likely to accept your projects if you involve them in the planning."

Although this example is not from a scientific field it conveys the general idea. The are several examples of shortening sentences and replacing unnecessarily long phrases.

The documents are from his site at www.andrewwright.info

I have his permission to post them here and they can actually be used for any non-commercial purpose. I hope they may be useful to someone.
