I am happy to announce that John F. Beyers, of the University of Maryland University College, will be editing a new book called Teaching and Learning Mathematics Online, to be published by CRC Press in 2019. I have known John since 2010 when I started teaching as an adjunct at UMUC in the math department. Over the years, I realized there were difficulties and hard parts of teaching mathematics via distance education, different from what you see in an English or history course.
We want this book to collect the leading ideas and practices of teachers and professors at every level, and serve as an open exchange of good practices for teaching mathematics and statistics online. You can read the full call for chapter proposals here.
