Both teaching technical editing skills in a logical sequence from introductory through intermediate and advanced levels, and helping students learn how to offer creative help to authors call for a structured approach to the editing course. Editing students should already have a firm knowledge of spelling, punctuation, and grammar, as well as writing competence. The course is divided into four major segments--copy editing, content editing, development editing, and science interpretation--and is paced to equalize the work and gradually build students' skills. Copies of relevant articles, summaries of lecture materials, and guest lecturers provide sources for editing work. "Words Into Type" is also a useful reference for the course. Two kinds of homework and classwork help students develop editing proficiency: short practice exercises concentrating on specific editorial processes and technical editing of manuscripts from different scientific and engineering disciplines. This same course structure can serve equally well for company training programs and inhouse workshops. (HTH)
