Welcome to the third installment of the 4+1 Interview series. Today’s interview features Dana Ernst. Dana is a professor in the mathematics department at Northern Arizona University, a champion of Inquiry-Based Learning in mathematics, and an active writer about math and math education. I’ve known Dana for a couple of years, and he never fails to impress me with his clear-headed, positive-minded, student-centered approach to his work. His mountain biking exploits also inspire me to get up and exercise sometimes.
Enjoy the interview and make sure to catch Dana’s writing at his personal blog, the new Math Ed Matters blog (see below for more), on Twitter, and on Google+. If you missed the first two installments, you can click here for Derek Bruff’s interview and here for my interview with Diette Ward.
1. You’re well-known as a vigorous proponent of Inquiry-Based Learning. Tell us…

Jennifer Morton writes in the Chronicle this morning about the social and behavioral competencies that students in online classes develop – or rather, don’t develop – as compared to their peers in traditional face-to-face courses. She (quite rightly) points out that MOOCs and the like present an opportunity for disadvantaged students to get the proverbial leg up into higher education at a drastically reduced price, and (again, quite rightly) notes that to the extent that traditional education sticks to outmoded lecture-based pedagogy, there’s no reason for disadvantaged students not to turn to MOOCs. Well, no reason except this:
A college education bestows not just cognitive skills—mathematical, historical, and scientific knowledge—but practical skills—social, emotional, and behavioral competencies. Tenacious, confident, and socially competent employees have an edge over…

Yesterday I was doing some literature review for an article I’m writing about my inverted transition-to-proof class, and I got around to reading a paper by Guershon Harel and Larry Sowder¹ about student conceptions of proof. Early in the paper, the authors wrote the following passage about mathematical proof to set up their main research questions. This totally stopped me in my tracks, for reasons I’ll explain below. All emphases are in the original.
An observation can be conceived of by the individual as either a conjecture or as a fact.
A conjecture is an observation made by a person who has doubts about its truth. A person’s observation ceases to be a conjecture and becomes a fact in her or his view once the person becomes certain of its truth.
This is the basis for our definition of the process of proving:
By “proving” we mean the process employed by an…

Welcome to installment #2 in an ongoing series of 4+1 Interviews with interesting people in math, technology, and education. Our first interview in this series, with Vanderbilt University Center for Teaching Director Derek Bruff, is here. I have several more in process now, and I’ll be posting these about twice a month.
Today’s interview is with Diette Ward. Diette is an Electronic Resources and Instructional Librarian at Lee University in Cleveland, Tennessee. I met Diette during my week at the Appalachian College Association’s Teaching and Learning Institute, where I was a plenary speaker and led some workshops on the inverted classroom. Diette was one of a group of “embedded librarians” who partnered with the workshop track leaders to provide support and insight on how libraries can support instruction. I was really impressed by the intelligence and enthusiasm that these …

It’s my pleasure to introduce a new series here at Casting Out Nines called 4+1 Interviews. In each of these interviews, I’ve picked out someone who I believe has something interesting to say about mathematics, education, or technology and given them four questions to ask. And at the end, the interviewee gets to pick his or her own question to answer, hence the +1. One of my favorite things about my job and about blogging and Tweeting is that I come into contact with a lot of really smart people very frequently, and I thought it would be nice to share these folks with you. I’m hoping to post about one of these every 2-4 weeks, and the lineup of upcoming interviews is very exciting.
Our first interview in this series is with Derek Bruff. Derek is the Director for Vanderbilt University’s Center for Teaching and the author of Teaching with Classroom Response Systems: Creating…

Here’s an interesting study (paywall) by a team of psychologists from the University of Wisconsin-Whitewater and the University of British Columbia that speaks to just how strong is the link between our personal identity and the way we perform on academic tests, especially mathematics tests. In the study, a group of 110 female and 72 male undergraduates were given a 30-question multiple choice math test. At the beginning of the test, all participants were told that men usually outperform women on math performance. (Never mind whether this is true for the moment.) Then, one group of participants completed the test using their own names on the test papers, while another group used one of four fake names – two of which were male names and the other two females.
The males who took the test did equally well regardless of whether they used an alias or not – even if they used a female …

I’m at the American Society for Engineering Education Annual Conference right now through Thursday, not presenting this time but keeping the plates spinning as Mathematics Division program chair. This morning’s technical session featured a very interesting talk from Kathy Harper of the Ohio State University. Kathy’s talk, “First Steps in Strengthening the Connections Between Mathematics and Engineering”, was representative of all the talks in this session, but hers focused on a particular set of interesting data: What engineering faculty perceive as the most important mathematics topics for their areas, and the level of competence at which they perceive students to be functioning in those topics.
In Kathy’s study, 77 engineering faculty at OSU responded to a survey that asked them to rate the importance of various mathematical topics on a 5-point scale, with 5 being the…

Have you ever tried out a new instructional method or course design – like peer instruction or the inverted classroom – and had not just a few students become discontent but entire groups of students who band together to push back? Or even put together a Facebook group to protest? It’s not pretty. Following last week’s Teaching and Learning Institute, where I talked with several college profs about this and other potential pitfalls of the flipped classroom, I happened to catch this answer on Quora to the question, How does a company handle an anti-marketing campaign like Dump Dropbox? and it seemed to me there are a lot of potential applications of this problem to the problem of mass student pushback.
To begin, the answer’s author says:
1. In public, ignore it.
2. Quietly shore up your messaging on any points where they landed a good punch.
Don’t bring up the…

Sebastian Thrun of Udacity today announced that Udacity, Georgia Tech, and AT&T are teaming up to offer an online Master’s degree in Computer Science. Here is Thrun’s official announcement. The details are slim at this point but Thrun states that the course materials will be entirely free, that there will be a tuition charge if you want to have the actual credit-bearing Master’s degree certification, and non-credit certificates will be offered at “a much reduced price point”.
Without details, there’s not much to say at this point about all this, other than this is clearly a major advance in the reach of massively open online courses. Udacity was the first to partner with brick-and-mortar universities to offer academic credit for MOOCs, and just as others are beginning to follow suit, they have made the leap into graduate education.
What this means for traditional…

The Washington Post reports this morning (apologies if this is behind a paywall) about how some universities are (finally?) moving from in-class lecture as the basis for their “large lecture” courses to the flipped or inverted classroom. Says the article:
Colleges are absorbing lessons from the online education boom, including the growth of massive open online courses, or MOOCs. And some professors are “flipping” their classrooms to provide more content to students online and less through standard lectures.
William E. “Brit” Kirwan, chancellor of the University System of Maryland, said the system hopes the redesigned courses save money and boost performance.
“The passive, large lecture method of instruction is dead,” Kirwan said. “It’s just that some institutions don’t know it yet. We do.”
This is nice to hear, but watch out for that phrase, “saves money…
