I am very excited to present this next installment in the 4+1 Interview series, this time featuring Prof. Eric Mazur of Harvard University. Prof. Mazur has been an innovator and driving force for positive change in STEM education for over 25 years, most notably as the inventor of peer instruction, which I’ve written about extensively here on the blog. His talk “Confessions of a Converted Lecturer” singlehandedly and radically changed my ideas about teaching when I first saw it six years ago. So it was great to sit down with Eric on Skype last week and talk about some questions I had for him about teaching and technology.
You can stream the audio from the interview below. Don’t miss:
A quick side trip to see if peer instruction is used in K-6 classrooms.
Thoughts about how Eric’s background as a kid in Montessori schools affected his thoughts about teaching later.
Here are some items from around the web for your weekend enjoyment.
Here’s a great post on Medium by Nik Custodio in which he explains Bitcoin like I’m five. I think the audience level here is rather older than five, but it’s still probably the best explanation of the problems that Bitcoin attempts to solve, and how it solves them, that I’ve seen. (I wasn’t sure whether to file this under “Math” or “Technology” because it’s a lot of both.)
If you’ve ever been interested in standards-based grading, you won’t want to miss Kate Owens’ post An Adventure in Standards-Based Calculus where she lays out why, and bits about “how”, she intends to use SBG in her Calculus 2 course this semester. Don’t miss the link to George McNulty’s calc 2 syllabus at the end, which is a great example of how to use SBG in actual practice.
In this news item from the Washington post (h/t to @ValerieStrauss) we learn that Khan Academy is using “contractors” to check the accuracy of some of its videos. The report is prompted by an email exchange between the piece’s author and Sal Khan himself regarding the accuracy of one of the physics videos. In Khan’s response, he says:
We have deleted the video [a physics video that had an error in it]. We are trying our best to keep up with any errors on the site (both through feedback from users and peer-review from educators). I checked into why we didn’t notice this one earlier, either your friend or someone else did point this out in the comments but they did not surface to the top (we currently have contractors with math/science backgrounds reviewing much of the math material and the comments to find other issues like this). We do need to get better at making sure that…
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…
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.
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…
To answer that question, we have to go back to a previous paper by the authors [PDF]. (That one is in the queue this week to read and blog about.) In that paper, the authors did find a positive correlation between screencast use (which they tracked using stats for the class’ course management system) and overall performance. But – this correlation does not imply causation, and indeed when the data are sliced along various demographic lines, sometimes the students’ performance was better explained by GPA than by screencast use.
I haven’t gotten into that second paper yet, but what …
Screencasting is an integral part of the inverted classroom movement, and you can find screencasting even among courses that aren’t truly flipped. Using cheap, accessible tools for making and sharing video to clear out time for more student-active work during class make screencasting very appealing. But does it work? Do screencasts actually help students learn?
We have lots of anecdotal evidence that suggests it does, but it turns out there are actually data as well that point in this direction. I’ve been reading an article by Katie Green, Tershia Pinder-Grover, and Joanna Mirecki Millunchick (of Michigan State University and the University of Michigan) from the October 2012 issue of the Journal of Engineering Education in which they studied 262 students enrolled in an engineering survey course that was augmented with screencasts. Here’s the PDF. This paper is full of interesting…
Gary Matkin, the dean for distance education at [UC-Irvine, McKenzie’s home institution], said the problem had stemmed from Mr. McKenzie’s reluctance to loosen his grip on students who he thought were not learning well in the course.
“In Professor McKenzie’s view, for instance, uninformed or superfluous responses to the questions posed in the discussion forums hobbled the serious students in their learning,” said Mr….
