Last day at AIM: meet some of my new friends

One of the very best parts of the workshop this week has been the time I’ve gotten to spend with the people here, some of whom I had followed online or traded email with, but never met in person.  Others I had talked with briefly at conferences, and of course there are a couple of long-time friends as well.  Anyhow, the schedule has allowed for lots of time for collaboration and discussion.  In this post I want to introduce a few of these fine folks to you all and to make sure you’re aware of their various projects.

Greg Hartman, Virginia Military Institute

Greg is the lead author behind APEX Calculus, and has also written free and open materials on Matrix Algebra and using MATLAB. “APEX” stands for “Affordable Print and Electronic Textbooks,” and the books Greg and his colleagues have created are free to download and can be purchased in print at very low cost.  He’s done some very nice work with interactive 3D graphics, too, which you can explore if you download the PDF of the calculus text and explore the file in Adobe Acrobat (note:  it’s a big file, so may take awhile to load).

Alex Jordan, Portland Community College

Alex is a WeBWorK developer and, as mentioned in my previous post, is the primary person who’s figured out how to put live WeBWorK exercise in HTML via MBX.  Alex and his colleagues at PCC are working on developing and implementing the use of Open Educational Resources, and have a beautiful proof-of-concept in their Calculus Lab Manual for their first term differential calculus course.

Jim Fowler, Ohio State University

Jim is one of the leaders of MOOCULUS at Ohio State, and you really should check out the materials he and his colleagues have developed, including their video library.  Jim also has some very interesting results on assessment for how student attitudes and habits are linked to performance and understanding.

Volker Ecke, Westfield State University

Through my work at PRIMUS, I’ve been aware of Volker and his colleagues at Westfield for several years now.  They have a beautiful ongoing project that combines IBL and Liberal Arts Mathematics called “Discovering the Art of Mathematics,” and you can learn more about the project from that link, including sample materials for one of the course versions.  Their special issue in PRIMUS on art & mathematics is also forthcoming soon (I believe the next issue that will appear online at the first link above).

Mitch Keller, Washington & Lee University

I know Mitch through the MAA’s Project NExT and because he’s been a user of Active Calculus.  Indeed, Mitch is working on a chapter that he’ll contribute to AC-Multi at some point in the near future.  But his big project is an Applied Combinatorics Text that he wrote with his PhD thesis advisor.

Jennifer Nordstrom, Linfield College

Jen has an IBL game theory text that is also free and open, and she has been working closely with Rob this week to get her book up on GitHub and also to do the conversion to HTML.  You can go to that link now and download the text for yourself to check it out.

It’s been great to have Steve Schlicker here from GVSU, too, so that we can talk about issues with Active Calculus single & multivariable and to start to develop a plan for how we’ll go forward.  We have a lot to talk about and even more to do.

As fun as the week has been, it’s also a bit overwhelming.  So much to learn, so many decisions to make, so much to do.  Grin.  I could use a whole summer just to explore the materials that are listed above in this post and to learn and study what others have done and how they did it.  It will be great moving forward to try some new things, to endeavor to bring Active Calculus up to a level closer to the mature books of folks like Rob and Tom, and to continue to be part of this movement.

A huge thank you to AIM and the NSF for funding our week and making this workshop possible.  And of course to our fantastic organizers: Rob, David, and Kent.

More from AIM: developments in free & open math texts

So much to share, so just going to go with a bulleted list for now.  Hope to flesh out more over the coming months.

  • The American Institute of Mathematics is a cool place and they have an excellent organizational scheme.  About 30 of us with shared interests are fully funded to be here for the week.  Official day starts at 9 am and ends at 4:30.  A nice mix of presentations and small group work (the latter of our own choosing) and time to collaborate and think.  Every day I have learned a lot and made new friends and professional connections.
  • The technological advances that have been made by a small number of people in a few short years are utterly amazing.  As Rob noted on his blog, yesterday “there were several impromptu rounds of applause for some of the technical achievements.”  Following are a few of those achievements.
  • Alex Jordan – in concert with Rob – has figured out how to make live WeBWorK exercises in an HTML version of a text. (!!!)
  • Alex has also managed to embed live Geogebra “applets” in the HTML text.  (There are some oddities here with Java and HTML 5 that I don’t fully understand, but that Alex does.  If the GGB doesn’t render in your browser, it may be that you have to adjust your Java preferences or that I’ve not pointed you to the right version that is running HTML 5.)
  • David Farmer has developed a script that will take an existing LaTeX book, convert (most of) it to Rob’s new publishing language (Mathbook XML), and thus within a very short time frame a person can go from having just PDF output to having a book also in HTML (that will need some editing, but the heavy lifting has been done).  Just while we’ve been here this week, David has done this for a half-dozen people.  You send him your files, he works for an hour or so, then sends them back, and bingo!  You have a rough HTML version of your work that looks a lot like the professional examples below.  As an aside, David also has converted some 12,000 (that is not a typo) mathematics research articles from LaTeX to HTML.
  • And, of course, there’s Rob Beezer’s utterly amazing Mathbook XML.  It is not hard to learn to use, and the output is game-changing.  On Monday, I  wrote one of my GVSU colleagues with the subject line “I have seen the future of e-textbooks.”  Check out Rob’s sample article that demonstrates multiple features and the overall interface, or the sample book, which is based on Tom Judson’s actual book.  Rob has a great gallery of the books that are already being produced in XML at the main mathbook site: http://mathbook.pugetsound.edu/index.html.
  • Rob has many other great resources, including his “Book on Mathbook,” and his very helpful just-created “Git for Authors,” which I am starting to work hard to make sense of.  Both of these books are gifts to the rest of us and will let many more people use these fantastic tools.  Yesterday afternoon we had a great 90-minute small group session that Rob led which walked 7 of us through some key stuff with Git and building a collaborative text.  He describes the details more fully over on his blog.

Overall, I’m learning in a week what it would take me months to accomplish on my own.  Very grateful to AIM, Rob, David, Kent, Tom, and Alex for making this possible.  So excited for the work that’s going to follow this and all the ways that Active Calculus will get better.

AIM Workshop on Open Textbooks

Very excited to be at the American Institute of Mathematics in San Jose, CA, to spend a week at the workshop on free & open textbooks, MathBook XML, and all sorts of emerging options.  Three things are totally clear from the outset:

  • It’s an amazing group of 25-30 people here.  So many cool projects, smart folks, and opportunities to collaborate.
  • Knowls will be a life-changing experience (as David Farmer says).
  • Having Active Calculus in HTML designed for a smartphone is going to make students who’ve been reading the PDF on their phone much, much happier.

More to follow in the near future.

New Year Updates to AC

Happy New Year everyone.  Here are a couple of brief updates if you are planning to use Active Calculus in the upcoming winter semester.

Thanks to everyone who sent us errors they found in the text, as well as other suggestions.  Steve has updated the multivariable version of the text to fix all known errors, and you can download the most up-to-date text from the page above, or directly from http://gvsu.edu/s/Wb.

I have updated the errata page for the single variable edition, but haven’t changed the original PDF.  My reasoning here is that the current PDF matches the print version for sale, and I would prefer that the e-document and print document match exactly to limit confusion.  As such, I will be updating both at the end of the coming semester.  For now, please use the errata page as an overview of known errors.  As always, if you find additional errors, please contact me to share them:  boelkinm at gvsu dot edu.  You may download the 2015 version of the text from the page above or directly from http://gvsu.edu/s/xr.

Professor disciplined for not using a for-profit text, written by his department chair

This post on the Chronicle’s site basically speaks for itself:  a text, written by the dept chair, was used for 25 years and had “never been questioned“.  When a faculty member tried to do otherwise, he was disciplined.

All I can say is:  good grief.  Update:  via Adam Glessner, there appears to be much more to this story than the Chronicle reports.  His point about not letting facts get in the way of a good story is well taken.  At any rate, if you click through to read the Chronicle article, you should also be sure to read Adam’s comments below.  Adam, thanks for sharing this.

A MOOC on Real-World Calculus

One of the organizers of this MOOC just reached out to me and asked that I share information about this free online course:  see the interesting trailer at https://www.futurelearn.com/courses/real-world-calculus.  I love that there are people willing to share more about the subject with interested people for free, and to talk about it ways that share how the universe works.

“But you feel dirty …” – why HS kids have to buy TI Calculators

In the same way that publishers take advantage of students’ captivity when it comes to needing textbooks, Texas Instruments does the same.  Here’s a fantastic article on the subject that quotes a PA HS teacher who says “But you feel dirty, because you’re telling parents they need to buy a device, and I know I can teach without it.”

More from the article:

There’s no reason they should cost so much, and it’s shutting out students who can’t afford them. Just this past week, Amazon started selling Internet-capable Kindle tablets for $50 each. But a new TI-84 still runs a retail price of $100, and classrooms that use TI-Nspires (the newest addition to the TI line) are shelling out $140 a pop — about the price of a brand new Chromebook. All for a calculator that is older than the .MP3 file extension.”

Like for-profit textbooks, this is a battle that HS and college faculty need to fight.  There is no reason that TI should continue to cash in on our discipline like this, especially with an outdated technology for which they are overcharging.  As the article says:  use Desmos instead.  Or Geogebra, of course.

Active Calculus – errata pages

An overdue addition for Active Calculus (single) and the addition to AC Multivariable that prompted it:  errata pages for both.

You can find a list of currently identified errors in each text at these links:  single variable, multivariable.

Of course, if you find errors that need to be added to either page, please contact me.

From my Amazon feed: Stewart’s Calculus for $272.52

In recent recommendations from Amazon, based on my prior reading and buying, I got an email suggesting that I buy James Stewart’s Calculus text.  Heh.

The 7th edition, no less: http://amzn.to/1Ly4mWi.  At least you can rent it for $50 for the semester.

These annual complaints about textbook costs are at least getting shorter.

Screencasts for Active Calculus

In a recent post, I highlighted several different resources available to go along with Active Calculus.  I realized yesterday that I omitted a key one, one for which there have been recent additions.

The Math 201 playlist on the GVSU Math YouTube Channel has now been around for awhile, with 92 videos and almost 65,000 views.  It includes screencasts for each section of chapters 1-4 of Active Calculus, and was developed by my colleagues Robert Talbert and Marcia Frobish.

With work over the past several months by GVSU Math faculty David Clark, Shelly Smith, Steve Schlicker, along with more contributions from Robert Talbert and Marcia Frobish, we are delighted to now have a Math 202 playlist on our YouTube channel.  The 202 playlist also has over 90 videos and provides supplemental instruction for nearly all of the sections in chapters 5-8 of Active Calculus.

I want to express my deep thanks to all of these colleagues who have made this fantastic free resource available to calculus students everywhere.
