I recently read the proofs of an article for Teaching Geography on the use of GIS and GPS by teachers which will be published in the Spring 2021 edition of the journal.

It starts with some mentions of GPS 'fails', where people didn't have the common sense, or spatial awareness, to realise that the machine wasn't taking them on the correct route, such as the stories here.

There's also an intriguing question to end the article. When plates are moved by an earthquake (as happened in the 2011 quake which caused the Japanese tsunami), does the GPS still work accurately?

Thanks to Ben Ranson for his help with the article, and also to a number of other teachers who are quoted, and to Fred Martin for setting the original provocation.

Looking forward to seeing the print magazine later in January.
