Emails ‘pose threat to IQ’

An article
by the guardian talks about how email can become adictive and actually lower your IQ like drugs.

The distractions of constant emails, text and phone messages are a greater threat to IQ and concentration than taking cannabis, according to a survey of befuddled volunteers.

Doziness, lethargy and an increasing inability to focus reached “startling” levels in the trials by 1,100 people, who also demonstrated that emails in particular have an addictive, drug-like grip.

Respondents’ minds were all over the place as they faced new questions and challenges every time an email dropped into their inbox. Productivity at work was damaged and the effect on staff who could not resist trying to juggle new messages with existing work was the equivalent, over a day, to the loss of a night’s sleep.

I think the same thing could be said of any highly distractive activity. People don’t multitask as well as they think they do.

“This is a very real and widespread phenomenon,” said Glenn Wilson, a psychiatrist from King’s College, London University, who carried out 80 clinical trials for TNS research, commissioned by the IT firm Hewlett Packard. The average IQ loss was measured at 10 points, more than double the four point mean fall found in studies of cannabis users.

So I wonder what having 4 small children does to the IQ of an unorganized mother? It seems like it would have a similiar effect. I would like to see a study sh Continue reading “Emails ‘pose threat to IQ’”

Most Educated State in the US

The United States Census has some interesting facts on the education rates of each state. The chart below shows the percentage of adults over 25 years of age who have at least a bachelors degree. The top position goes to the District of Columbia, but since it is such a small area, it probably isn’t really fair to compare it with the other states. If we don’t count D.C. then the most educated state is Massachusetts where you stand a 36% chance that anyone you happen to meet has graduated with a four year degree.

Capella’s IPO

Capella announced that it is going to go public. Capella has always looked like an interesting university. They are a commercial enterprise and based on their requirements it seems that they probably rank a little higher academically than University of Phoenix.

“Capella Education Co. of Minneapolis, one of the few private education firms to offer college degrees exclusively through online courses, said Monday it plans an initial public stock offering that could raise up to $86.25 million.”

“Capella, the parent company of Capella University, will use proceeds from the IPO for working capital and general corporate purposes, which could include expansion, developing new courses and acquisitions, the company said.”

It will be interesting to see how they put this money to use. Developing online courses can be very expensive. If they are able to create a solid infrastructure for creating courses, it could help them leap ahead of the competition. Currently the two places that seem to be successfully doing online education are Harvard and Standford. Their online classes mirror live classes and they do a good job of keeping the experience the same (as much as possible) for both the online and real time students.

Online learning is a growing market into which private companies have raced since the late 1990s, partly because traditional colleges and universities were slow to adapt to online teaching.

One of the reasons traditional institutions have been slow to react is because of the expense of being cutting edge. It is a lot less expensive to put a class online that it was a few years ago, but it is still a major undertaking. I think most colleges and universities are looking at it, but most don’t have the money to successfully pull it off.

Capella attributes its growth partly to growing acceptance of online education and to its relationships with companies, colleges and branches of the U.S. military that have endorsed its online services to their employees or students.

I think this is the key. Capella is not inexpensive. Most people aren’t going to take classes unless they are paid for by their employer. If Capella can sell themselves to large companies as a way for their employees to take classes without needing to be gone from work, they can get a tremendous number of student. I was at a Franklin Covey training session where I met someone who works for GM. He said he was working on his PHD through Capella. I got the impression that a good number of GM employees are doing this as well. A good number of them will probably never complete the degree.

I am concerned about institutions that opt for a cheap way of doing online education where it is basically correspondence school using the internet instead of USPS. A lot of these classes rely on relatively light reading assignments and much of the student’s time is spent on message boards with other students. I don’t think that the message boards is necessarily a bad way to learn and interact, but I think it can keep people from really learning how to concentrate on a subject for a long period of time.

You should be able to assume that a college graduate can stay engaged in a day long seminar because they should have learned that level of concentration in order to get their degree. If their educational experience was primarily reading and responding to short posts, they may never develop the skills necessary to assimilate 3 hours of information from a dense lecture.

Another problem with some of the modern teaching theory is the idea that if you just make a bunch of people interact with each other, their life experiences will rub off and everyone will be smarter. In some cases this is the idea behind using the message boards. I think it is valuable to learn from your fellow students. In fact that is one of the reasons that I really like learning in an actual classroom. But I think that learning that is primarily based on talking with other students about their experiences in life falls short of true education. In most fields of study that have been around long enough to reach some sort of structure, simply talking with other students won’t allow you to cover the material very quickly. A group of freshman music students are unlikely to really understand the fundamentals of music theory just by chatting with each other. That isn’t to say that chatting won’t produce some valuable interaction, but they aren’t likely to learn the majority of what they need to know this way.

I think online courses are most effective when they mirror an actual class with videos of the teacher lecturing. I don’t think this is how Capella is currently doing their classes.

I think the best thing that a company like Capella could do is partner up with existing institutions and re brand the lectures from the top lecturers in each field. Teaching fellows could help facilitate the day to day questions and course management. The professors themselves would need to be available in some capacity as well. If this was done correctly the academic experience from Capella could be better than going to a physical university because students would get to study under the best teacher for each class. Recent high school graduates would still want to go to a physical college or university because the social education is just as important as the academic education, but older students looking to continue their education could have a greater trust in the academic soundness of their university even if it is only a virtual one.

Virtual Private Linux Servers

There used to be two choices for web hosting. You could get a dedicated server for several hundred dollars each month. This would give you complete control of your machine letting you schedule automatic jobs to run, upgrade packages, etc. Or you could share a server with a bunch of other people. This would keep your expenses low (sometimes under $10 per month or even free), but you were restricted to basically just uploading static pages or PHP.

There is some software out there called user mode Linux that lets you create virtual machines on one physical box. This means hosting companies can put in one server and share it among several users. The users get complete control (including root access) at low prices. For people who want to host small to medium sites, this is perfect. They still get complete control and shell access, but they don’t have to pay for an entire machine.

  • Easy Co — Currently I’m hosting www.markwshead.com at EasyCo. They have good service and telephone tech support. I pay about $15 per month for their base level package.
  • Redwood Virtual — I host blog.markwshead.com with Redwood. They don’t have telephone support, but their prices are even cheaper. It is only $8.33 per month if you pay for a year upfront. They recently added an interface that allows you to reboot your system if it gets hung, so this makes the telephone support less of an issue. It will also let you reinstall everything back to the original settings which can be nice if something gets terribly messed up.
  • Open Hosting — I just ran across this company the other day. Instead of limiting your virtual machine to the resources you’ve paid for, they will give you a base package and then charge you for the extra usage at the end of the month. If you are like me where your machines sit idle or just serving http 95% of the time, this may be a good way to get a lot more power while still keeping costs down. Currently with Redwood and Easy Co, I’m running into limitations because of the amount of RAM I’m paying for. I can’t run some of the tools I need, but it is hard to justify upgrading to the next level when I only need to run the tools once or twice a month. Right now it is cheaper to do it offline and upload the results. A setup like Open Hosting might work very well because I’d have the extra resources when I needed them.
