It’s been pretty quiet around here at Casting Out Nines lately. This is mainly due to two things. First, I’m spending five days a week home with my oldest two kids — the youngest joins us on Wednesdays — and keeping the kids active and engaged doesn’t leave much time for blogging. Second, as you all know, I’m starting a new position at Grand Valley State University in the fall and our big move to Michigan takes place in two weeks. We’re totally uprooting in this move, and preparing for it consumes a lot of time and emotional energy.
I’ve decided that, in light of all this, that I might as well declare the blog to be on hiatus for a month or so until we’re settled. There are a couple of posts that might go up soon — one of them being the last entry in the How I make screencasts series — but…
Many people associated with educational technology are driven by a passion for helping students learn using technology in a classroom setting. But I wonder if many ed tech people — either researchers or rank-and-file teachers who teach with technology — ever consider a slightly different role, voiced here by Seymour Papert:
Many education reforms failed because parents did not understand or could not accept what their children were doing. Remember the New Math? This time there will be many who have not had the personal experience necessary to appreciate fully the multiple ways in which digital media can augment intellectual productivity. The people who do can make a major contribution to the success of the new initiative by helping others in their communities understand the potential. And being…
I’ve just finished up the spring semester, and with it the second iteration of the inverted classroom MATLAB course. With my upcoming move, it may be a while before I teach another course like this (although my experiments with targeted “flipping” went pretty well), so I am taking special care to unwind and document how things went both this year and last.
I asked the students in this year’s class about their impressions of the inverted classroom — how it’s worked for them, what could be improved, and so on. The responses fell into one of two camps: Students who were unsure of, or resistant to, the inverted classroom approach at first but eventually came to appreciate its use and get a lot out of the approach (that was about 3/4 of the class), and students who maybe still learned a lot in the class but never bought in to the inverted method. No matter what the group, one thing was a …
We’re in final exams week right now, and last night students in the MATLAB course took their exam. It included some essay questions asking for their favorite elements of the course and things that might be improved in the course. I loved what one of my students had to say about the assignment in the course he found to be the most interesting, so I’ve gotten permission from him to share it. The lab problem he’s referring to was to write a MATLAB program to implement the bisection method for polynomials.
It is really hard to decide which project I found most interesting; there are quite a few of them. If I had to choose just one though, I would probably have to say the lab set for April 6. I was having a really hard time getting the program to work, I spent a while tweaking it this way and that way. But when you’re making a program that does not work yet, there is this sort of golden…
This past Saturday, I was grading a batch of tests that weren’t looking so great at the time, and I tweeted:
I do ask these two questions a lot in my classes, and despite what I tweeted, I will probably continue to do so. Sometimes when I do this, I get questions, and sometimes only silence. When it’s silence, I am often skeptical, but I am willing to let students have their end of the responsibility of seeking help when they need it and handling the consequences if they don’t.
But in many cases, such as with this particular test, the absence of questions leads to unresolved issues with learning, which compound themselves when a new topic is connected to the old one, compounded further when the next topic is reached, and so on. Unresolved questions are like an invasive species entering an ecosystem. Pretty soon, it becomes impossible even to ask or answer questions about the material…
A while back I wondered out loud whether it was possible to implement the inverted or “flipped” classroom in a targeted way. Can you invert the classroom for some portions of a course and keep it “normal” for others? Or does inverting the classroom have to be all-or-nothing if it is to work at all? After reading the comments on that piece, I began to think that the targeted approach could work if you handled it right. So I gave it a shot in my linear algebra class (that is coming to a close this week).
The grades in the class come primarily from in-class assessments and take-home assessments. The former are like regular tests and the latter are more like take-home tests with limited collaboration. We had online homework through WeBWorK but otherwise I assigned practice exercises from the book but …
On Wednesday, I gave a talk at Indiana University – Purdue Universty – Indianapolis (IUPUI, for short) to the teaching seminar for math graduate students on the inverted classroom. It was sort of a generalization of the talk I gave on the inverted linear algebra classroom back at the Joint Mathematics Meetings in January. Carl Cowen was in attendance at that talk and invited me to make the 20-minute drive from my house to IUPUI to do something like it, and I was happy to oblige.
Since putting the talk up on Slideshare yesterday morning, it’s gotten over 200 views, 2 favorites, a handful of retweets/Facebook likes, and is currently being highlighted on Slideshare’s Education page. So I thought I would share it here as well. Enjoy and ask questions!
Between the Salman Khan TED talk I posted yesterday and several talks I saw at the ICTCM a couple of weeks ago, it seems like the inverted classroom idea is picking up some steam. I’m eager myself to do more with it. But I have to admit there are at least five questions that I have about this method, the answers to which I haven’t figured out yet.
1. How do you get students on board with this idea who are convinced that if the teacher isn’t lecturing, the teacher isn’t teaching? For that matter, how do you get ANYBODY on board who are similarly convinced?
Because not all students are convinced the inverted classroom approach is a good idea or that it even makes sense. Like I said before, the single biggest point of resistance to the inverted classroom in my experience is that vocal group of students who think that no lecture = no teaching. You have to convince that group that what’s…
Salman Khan, of the Khan Academy, sounds off on the potential of pre-recorded video lectures to change education in the video below. He calls it “flipping” the classroom, but around here we call it the inverted classroom.
I like especially that Salman made the point that the main effect of inverting the classroom is to humanize it. Rather than delivering a one-size-fits-all lecture, the lecture is put where it will be of the most use to the greatest number of students — namely, online and outside of class — leaving the teacher free to focus on individual students during class. This was the point I made in this article — that the purpose of technology ought to be to enhance rather than replace human relationships.
I hope somewhere that he, or somebody, spends a bit more time discussing exactly how the teachers in the one school district he mentions in the talk actually…
I’d be interested in hearing your thoughts on the following statement about responsibilities in college:
In college, it’s the student’s responsibility to initiate requests for help on assignments, and it’s the instructor’s responsibility to respond to those requests in a helpful and timely way.
Do you think this statement is true or false? If false, could you modify it so that it’s true?
