Can online students become socialized?

3770483632_6b6a8e83e6_mJennifer 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…

Examples and the light bulb

6186929069_f72cf92699_nI have a confession to make: At this point in the semester (week 11), there’s a question I get that nearly drives me to despair. That question is:

Can we see more examples in class?

Why does this question bug me so much? It’s not because examples are bad. On the contrary, the research shows (and this is surely backed up by experience) that studying worked examples can be a highly effective strategy for learning a concept. So I ought to be happy to hear it, right?

When people ask this question because they want to study an example, I’m happy. But studying an example and seeing an example are two radically different things. Studying an example means making conscious efforts to examine the example in depth: isolating the main idea or strategy, actively trying out modifications to the objects involved, making connections to previous examples and mathematical results, and – very …

Udacity to partner with Pearson for testing: What does this mean?

Online educational startup Udacity, with whom I had a very positive experience while taking their CS 101 course, is taking things a bit further by partnering with Pearson. They’ll be using Pearson VUE testing centers worldwide to provide proctored final exams for some of their courses (presumably all of their courses will be included eventually), leading to an official credential and participation in a job placement service.

Before, students watched the videos and did homework assignments online and then took a final exam at the end of the semester. In the first offering of CS 101, the “grade” for the course (the kind of certificate you got from Udacity) depended on either an average of homework scores and the final exam or on the final exam alone. Most Udacity courses these days just use the final exam. But the exam is untimed and unproctored, and there’s absolutely nothing…

Can Math Be Made Fun?

This article in the Chicago Tribune talks about efforts to make math fun:

In the American drive to boost science and math education, it’s science that has all the kid-friendly sizzle: Robots and roller coasters, foaming chemical reactions, marshmallow air cannons.

Math has… well, numbers.

“America has a cultural problem with math. It’s the subject, more than any other, that we as a country love to hate,” said Glen Whitney, a passionate mathematician who worked for years developing algorithms for hedge funds. “We don’t see it as dynamic. It’s rote and boring and done by dead Greek guys a thousand years ago.”

The article goes on to talk about some efforts to spice up math, including MIT’s Labyrinth tournament, DimensionU‘s celebrity-driven “DU the Math”…

Encountering abstraction with clickers

I had the great pleasure this weekend of leading a session at Math In Action, which is Grand Valley’s annual K-12 educators’ conference. My session was called “Classroom Response Systems in Mathematics: Learning math better through voting” and was all about the kinds of learning that can take place in a class where active student choice is central and clickers are mediating the voting. (Here are the slides.)

It always seems like a bait-and-switch when I do a “clicker” workshop, because although people come to learn about clickers, I don’t really have much to say about the technology itself. As devices go, clickers are about as complex as a garage door opener, and in fact they work on the same principle. There’s not a lot to discuss. So instead, we spend our time focusing on the kinds of pedagogy that clickers enable — which tends to excite teachers more than technology does.

The a…

What makes kids want to become engineers?

Many indicators are pointing to a critical shortage of engineers among the current high school generation. What’s the cause of all that? A study (PDF) by the nonprofit organization Change the Equation (with backing from Intel), focusing on 1004 students between the ages of 13 and 18 with computer access, suggests two things: a perception of difficulty coupled with an overall lack of knowledge about what engineering really is in the first place.

The Intel survey showed 63 percent of the students ages 13 to 18 have never considered the career despite having “generally positive opinions of engineers and engineering.” The perception that engineering is difficult also played a part in the lack of job consideration.

But the teens were especially interested when they learned about the potential for engineering to help others, such as saving the Chilean miners who were trapped in 2010,…

Helping the community with educational technology

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…

A binary notion of "understanding"

Another great insight from Seymour Papert, via The Daily Papert blog. I put it up on my Posterous blog this morning but I thought it could go here too:

Many children who have trouble understanding mathematics also have a hopelessly deficient model of what mathematical understanding is like. Particularly bad are models which expect understanding to come in a flash, all at once, ready made. This binary model is expressed by the fact that the child will admit the existence of only two states of knowledge often expressed by “I get it” and “I don’t get it.” They lack—and even resist—a model of understanding something through a process of additions, refinements, debugging and so on. These children’s way of thinking about learning is clearly disastrously antithetical to learning any concept that cannot be acquired in one bite.

Eliminating STEM majors in the name of efficiency?

Missouri State University

Image via Wikipedia

Thanks for bearing with me during a little hiatus on this blog. I’ll be back into semiregular posting habits starting now.

Problem: There’s not enough qualified candidates with degrees in the STEM disciplines for the STEM jobs that are coming on the horizon, particularly those that require US citizenship such as government jobs. So you would think that the solution would be to try to drum up more students to go into, and stay in, those disciplines. But Missouri State University has chosen to take a different track: Start eliminating STEM majors because they are “low producing programs”. From the article:

Gov. Jay Nixon directed the agency to review academic programs that do not appear to meet the Coordinating Board for Higher Education’s productivity criteria.

“Low-producing programs” are…

Conrad Wolfram's vision for mathematics education

A partial answer to the questions I brought up in the last post about what authentic mathematics consists of, and how we get students to learn it genuinely, might be found in this TED talk by Conrad Wolfram called “Teaching kids real math with computers”. It’s 17 minutes long, but take some time to watch the whole thing:

[ted id=1007]

Profound stuff. Are we looking at the future of mathematics education in utero here?
