When I saw the topic of your post, I immediately thought "this person is coming from Canvas." Yes, Canvas has a "syllabus" feature. However, this is Canvas' view of what a syllabus looks like to them (and maybe more like what I would call a table of contents). At my school, no instructor used this Canvas "syllabus" because it never match any "traditional" view of what a college syllabus should look like. Well, be that as it may, it's Canvas.
No, Moodle doesn't have that kind of feature. But you have many alternatives available.
1) Expanding on what Mary posted, you could use Moodle's "File" resource and attach the syllabus as a PDF, Word, or whatever filetype format.
2) You could use a Forum, somewhat like the File resource, but a forum would allow students to ask questions about the syllabus.
3) You could keep all syllabi on your university website, then use a Moodle
URL to link to it.
In my case, I kind of do the #3 suggestion. However, my syllabus is in HTML, as a web page. My school always wanted syllabi to be MS Word files, but I argued that an HTML file was better for many reasons, so I went against the wave. Students never complained, either. I could then reference my syllabi anywhere, such as "
MBA8150 Syllabus," and I knew that it would be correct because I managed it in one central location. Also, since it is a web page, I don't have to worry about how students will open it; it just appears on a new tab. However, this method (using the Internet as intended) seemed to be beyond the scope and ability of most college professors. 😑
Anyway, in different LMSs you often need to do things differently. Below is a screenshot showing how students see my syllabus in Moodle 4.1. This "Course Administration Items" section always shows at the top of my course.
