Technology in the classroom

Standard

Now with all the 2014 seniors settling into their college sweatshirts, trying not to sweat the future, it is time for the glitz and glamour of graduation presents. New laptops or tablets, even a new phone as well.

We all know what the technology will be used for, Netflix binging, video games, and Facebook (mainly), but now more than ever technology has become and essential part of learning. People download textbooks, upload and email homework to teachers, even work on group presentations through the wonderful world of Google Drive. A basic laptop has become the most important back to school item on anyone’s list.

It has even made note taking easier. Instead of carting around a backpack full of notebooks and textbooks, I can bring my laptop. I have everything I could need in one small package. No need for loose paper or pens, I can do everything digitally. My bag has gone from ~20 pounds to around 7 pounds. Because I can type fast, I can also basically transcribe lectures as well, making sure I do not miss  a word.

Unfortunately not all technology in the classroom is a good thing.

A couple of days ago, this Atlantic article came across my attention.

The article highlights a new study from the Psych department of Princeton. It found that people remember a lecture when they take notes by hand rather than on the computer.

This turn out to be because laptop note takers tend to transcribe what the teacher is saying. Because typing has become, in many ways, faster than actual hand writing to many students, people tend to copy the teacher word for word in hopes of not forgetting a thing. But this method lacks an important step in handwritten notes: being judicious, and having an inner conversation while you are taking notes.

Because most people do not have the ability to accurately and speedily transcribe a live event without a recording, note taking creates an inner dialog. You have to process what is being taught as well as write it down. The selectivity of your notes leads to long-term comprehension.

Long-term comprehension you don’t get with a laptop.

Even laptop note taking students who were encouraged to write in their own words and not verbatim did not remember as much as a pen and paper note taker. The study found that not only were computer using students did not perform as well academically, they were also less happy with their education.

The study did not examine the use of tablets as not taking. But, Pam Mueller, a student that help to lead the experiment said, “Tablets might be the best of both worlds—you have to choose what to write down, but then you have the electronic copy.” in the Atlantic article. 

So next time you consider pulling out your laptop, maybe think twice.

The Importance of BOINC

Standard

Recently while perusing Reddit, I came across a computer program that is truly the coolest thing ever. An open source program that utilizes your idle computer time to help scientific research. This project is called BOINC.

This project, run by University of California–Berkeley is a platform for research projects to come online and find volunteers to donate their idle computers to help process data.  The original version was the SETI Project (a project that searches for radio signals in space to search for extra terrestrial life) that is still in operation today, and something you can still donate your time to.

Private research companies, scientist, and universities, all use the program to find people to support their work. There are currently around 50 projects to choose from. Projects in every field of science you can think of.

How the program works is, you choose the program(s) you want to support, download the BOINC software, and watch your computer help the scientific community.  It runs like this:

  1. Your PC gets a set of tasks from the project’s scheduling server. The tasks depend on your PC: for example, the server won’t give it tasks that requires more RAM than you have. Projects can support several applications, and the server may send you tasks from any of them.
  2. Your PC downloads executable and input files from the project’s data server. If the project releases new versions of its applications, the executable files are downloaded automatically to your PC.
  3. Your PC runs the application programs, producing output files.
  4. Your PC uploads the output files to the data server.
  5. Later your PC reports the completed tasks to the scheduling server, and gets new tasks.

This cycle goes for as long as you run the program.

It can be used on Windows, Mac OS, Linux, even Android smart phones.

Because of the importance of helping the scientific continuity, and just the general cool factor, I think Lane should install the program of the school computers.

There are several hundred Macs and PCs throughout the school. Many are only used for a couple of periods. With this much computing power, think about ll the help we could be for these programs. It would be so cool if one of Lane’s computers found extraterrestrial life with Cosmology@home or helped prevent Malaria with MalariaControl.

Granted, The programs use the CPU/GPU of a computer and therefor can use some electricity. But, the computers are always on, and are always plugged in. These computers are constantly using electricity.

Its free, safe, and effective. The real question is, why are we not already doing this?
