Peer-review doesn't happen only in classrooms or in face-to-face situations. A writer can share a text with peer-review readers in the context of a Web classroom. In this context, the writer's text and the reader's response are shared electronically using file-sharing, e-mail attachments, or discussion forums/message boards.
When responding to a document in these ways, the specific method changes because the reader can't write directly on the document like they would if it were a paper copy. It is even more important in this context to make comments and suggestions clear by thoroughly explaining and citing specific examples from the text.
When working with an electronic version of a text, such as an e-mail attachment, the reader can open the document or copy/paste the text in Microsoft Word, or other word-processing software. In this way, the reader can add his or her comments, save and then send the revised document back to the writer, either through e-mail, file sharing, or posting in a discussion forum.
The reader's overall comments can be added either before or after the writer's section of text. If all the comments will be included at the end of the original text, it is still a good idea to make a note in the beginning directing the writer's attention to the end of the document. Specific comments can be inserted into appropriate places in the document, made clear by using all capital letters enclosed with parenthesis. Some word-processing software also has a highlighting feature that might be helpful.
