In text/html yes, but you have the choice to use XHTML5
(application/xhtml+xml) if you prefer XML's strictness.

You'd just have to teach XHTML5. But if you don't teach them XML (i.e.
you're teaching them "XHTML 1.0 Appendix C" [1], then you're lying to
your students: you're not teaching them XHTML, you're teaching them a
"buggy HTML 4" that looks like XHTML.

In the HTML5's text/html serialization, trailing slashes in void
element's start tag are allowed (to make that "buggy HTML 4 that looks
like XHTML" [1] valid, by allowing void element's start tag to look
like XML's EmptyElemTag [2]).

...so you could continue to teach your students the same coding
standards / guidelines and now really be teaching them valid HTML ;-)
