Grammar matters. Users are far more likely to engage and trust a site with proper grammar. Since we have users from all walks of life, some for whom English is not their first language, many posts on iFixit could use some grammatical correction. Have students find guides, questions, answers, or wikis that need grammatical improvement, then make them better. We even have a page that shows the guides that are in need of some serious grammar edits. Be sure to have students show before/after versions or review the history of the guide to see the improvements made. These small changes will really help users get the information they need to repair a device.
