Here is work that was done by groups of my community college students.
Many are ESL and/or in remedial writing and math
The work is “published” on the web and is therefore public – any one in the world with internet access can see the students’ work. Knowing this has been beneficial. Students have been willing to ensure that the work of the group reflects the high standards of web content. As these are group projects, many more students participate in the product of a public document.
