Hello!
Several years (2013-2017) my students (Petrozavodsk State University) edited and created articles in Russian Wiktionary.
During the course: 1) We discussed the corpus linguistics. 2) Study the Russian National Corpus, and how to search good examples of sentences for the dictionary. 3) Learn the structure of the Wiktionary entry (article).
This page in ruwikt (https://ru.wiktionary.org/wiki/%D0%A3%D1%87%D0%B0%D1%81%D1%82%D0%BD%D0%B8%D0...) describes the task and lists the students with assigned words. I will translate it briefly:
The task for the students is to create a good article in native language (Russian), namely:
0) Students select the words, which are absent in the Russian Wiktionary, or words, which have empty section "Meaning". I provide students with the list of such words.
1) Meaning. Take two or more solid (usually paper) dictionaries and compile the description of the sense. If this is new word, then provide good usage examples in order to validate your meaning. (Teacher lists titles of good dictionaries.)
2) Find in the online corpus (e.g. in Russian National Corpus) good usage examples and add them to your Wiktionary article. Two or three examples for each meaning.
3) Fill all sections of the Wiktionary entry (really all, even categories), except an etymology, since the etymology section is very complex part (at least in Russian Wiktionary).
4) Make audio for your words (phrase) and upload it to the Commons. We recorded audio at the lesson, I brought the good quality microphone to the class. It was the most fun lesson in the course :) Not every student selected respectable words for the work.
Professional editors of the Russian Wiktionary are invited to supervise the student work. It saves students and helps to the teacher :)
This editing of Wiktionary were done by student at home. In the class one or two students show their results (in public, with projector) and we discussed the common errors in order to prevent these errors in the work of other students.
I have tried do not edit the Wiktionary entries itself, and I wrote all my comments to the students at the corresponding talk pages.
P.S. Now the editing Wiktionary is additional task for not successful students. The first place for my research with students is Wikiversity and Wikidata, see https://en.wikiversity.org/wiki/Research_in_programming_Wikidata
