As I mentioned back in February, there are some glitches in the WordPress software that drives this blog. Probably I need to install an updated version of PHP to increase the blog’s security and stability, and this will force a change in the blog’s appearance. In other words, a new look, but same content and mission.
Along those lines, I would like to invite ideas for guest posts about the new assignments, exams, and techniques that all of you are now developing for an unprecedented fall semester. These ideas can be sent to us at firstname.lastname@example.org. The Covid-19 pandemic is forcing a radical re-think of teaching, and we all know that even the best-designed experiments often do not perform as desired. We welcome examples of failure as well as success, since the former is often more instructive than the latter.
