My coauthor has released a self-contained module with some theory and various hypotheticals that educators can use in classes [2].
I've been trying to crowdsource a set of real-world case studies with a broad coverage of various types of ethical issues [3]. I'm also gradually trying to incorporate this in my own teaching.
We'd appreciate feedback and suggestions.
