Identify when it is appropriate for a scientist to use highly technical jargon and a structured format in their writing.
in communicating with other scientists
in writing books that help interest the general public in science
during television or radio interviews
in providing information to the media
The only appropriate situation, would be in communicating with other scientists. Since these other scientists would know the jargon. All the other answers lead information to the general public, in which case jargon shouldn't be used.
