Easy update for Lithium!

One of the best things about OER texts is they’re easy to update. This week I’m teaching a unit in my American Environmental History course on mining, using an chapter from my text called “Treasures Underground“. It begins in Potosí where the Spanish Empire got much of its silver, talks about the gold and silver rushes in the western US, and then moves on to oil before returning to the effect of minerals on foreign policy in an increasingly globalized economy. The examples I used in the text (which I published last year) were oil in Iran and copper in Chile — and the two US-supported coups that toppled democratically-elected governments in those nations.

Today I added an additional example, as it seems democratic elections in Bolivia have been subverted this week in another coup. So ironically, the chapter now begins and ends in Bolivia. Evo Morales, the country’s immensely-popular indigenous president, has been forced to step down and has sought asylum in Mexico slightly over a week after pushing back on the rapid, foreign-controlled development of Bolivia’s lithium reserves.

This is the slide of Morales and the Salar de Uyuni (Bolivian source of lithium) I’m adding to my lecture this week. I’ve also added these images to a new conclusion for my OER chapter.

Lithium is a key element (along with cobalt) in the rechargeable batteries that run cell phones, computers, and electric cars. The price of lithium has about tripled since 2015, and Bolivia has about 43% of world reserves (Argentina, Chile, and Bolivia between them control about 75%). Although advanced car companies like Tesla are rapidly reducing the quantity of lithium in each battery cell, other car companies that buy off-the-shelf battery solutions are likely to use much more. And everybody is trying to get into the electric car business right now.

One of my goals in this course (which is actually called “People of the Environment” and is a required “sustainability” course at Bemidji State) is to connect environmental history with the world my students face today. What better way to bring the story of mineral resources to the present than with breaking world news? It’s great that the OER tools I’m using enable me to react rapidly and incorporate this into my chapter. This is a strength of OER we should talk more about in our advocacy.


Setting up Hypothesis

I just made a short video to introduce my students to Hypothesis. I’ll be using it for annotation and discussion in all my online and in-person courses this fall. After they’ve watched the video, I have the students create an account, follow a link I provide to the private group I’ve set up for each section, install the plugin in their browser, and leave at least one comment on the course syllabus. Here’s the video:

Adding to OER ebooks

One of the useful aspects of Pressbooks is that authors can edit a title and add content whenever they need to. This allows errors to be corrected and materials to remain up to date as new information becomes available. How often have you discovered a problem in a textbook you’re using, and hoped it would be caught and corrected in the next edition in a few years?

Keeping up with research isn’t an issue only in the sciences, though. New information becomes available in all fields as researchers continue discovering new facts or refining their interpretations. For example, I recently discovered another historical source for my volume of primary readings relating to the Ranney brothers and their migrations across the continent in the nineteenth century.

The source wasn’t exactly new: it was a volume called the Compendium of history and biography of Hillsdale County, Michigan, written by Elon G. Reynolds in 1903. Reynolds’ work was typical of the genre, including about 80 pages of general history of the county and then over 450 pages of short biographical sketches of Hillsdale’s leading men and institutions. On pages 302 and 303 there is a sketch of Henry Ranney’s younger brother, Lemuel Sears Ranney.

The passage adds some details to Lemuel’s life I was not aware of, provides validation of some of the events Lemuel and his brothers describe in their letters, and gives us an interesting look at the elements of Lemuel’s story that seemed interesting to the editors of this 1903 volume, and presumably its readers. It also shows the degree of respect Michigan residents seem to have had for Ranney, who was still alive when the book was published.

This was all interesting enough to me that I wrote an extra short “chapter” about it and added it to the end of my ebook. Readers who are reading it online will find it automatically appended after the previous final chapter that covered Henry Ranney’s obituary. Folks who have downloaded the ebook or pdf versions to their own devices can return to the Pressbook’s homepage and download another. I’ll probably not be adding a lot more to this volume, but if I come across any new material it’s nice to be able to!

“Podcast” Chapters

I’ve made video lectures of chapters from my American Environmental History text — now I’m also making audio “podcasts” of the chapters so people can listen tot he chapters on the go. Here are the first three:


Chapter 1: Prehistory

Chapter 2: Recontact
