The New Sputnik

In 2007 Vinton Cerf, a founding father of the Internet wrote that what this country needs is another Sputnik to reinvigorate science education. After reading Cerf’s article, last spring I did a research project on the National Defense Education Act. The NDEA was the US response to the launch of Sputnik, hoping to improve schools and better compete with the perceived Soviet threat.

Today, on Daniel Pink’s blog, I find another interesting reference to this landmark event. This time it was a video of James Paul Gee discussing education reform. A few of the highlights I picked up on in the video include:

  • Global competition will be the new Sputnik, and American education has a 50% chance it will experience the first real reform in 100 years as a result.
  • Teachers have become de-professionalized, letting textbooks, testing and politicians make curriculum decisions rather than teachers making professional decisions about what and how best to teach. (Not an indictment of teachers, just a statement of current reality.)
  • Innovation and creativity are not emphasized enough because many schools are simply test-prep academies.
  • Social media helps to create “passion groups” through which people with similar passions can come together
  • Teachers learning to use new digital tools are model learners for students

If you have 11 minutes or so, why not enjoy the entire video?

Free Tools You Really Use

Oh Yeah!Sometimes I take it for granted that colleagues and friends know about most of the same technology tools that I know and use, but it just ain’t so! Likewise, they know about things that I don’t know about, so I am taking it upon myself to write a post compiling a list of  the tech tools that I use on a regular basis and hoping that other folks will do the same. (If you do, please comment here with a link to your list.)

These aren’t tools that I’ve heard about and dinked around with a bit; these are things I have discovered that have enough value that I keep returning to them. I will post my list here and I’m hoping you will comment with tools you frequently use as well.

  • Google the reigning king of all search engines. I frequently use Google Image Search as well.
  • Wikipedia Online Encyclopedia (everyone uses this now, right?)
  • Wikimedia Commons is a great place to find Creative Commons licensed images.
  • Magnatune is an excellent repository of low cost and Creative Commons licensed music.
  • Firefox Web browser extraordinaire. Love it for the 3rd party add-on tools
  • Stumble Upon use it to find a random website that matches your interests or to drive traffic to sites you like. I use it’s Firefox plugin
  • Diigo has all but replaced my browser favorite bookmarks. Save sites you like online, share with others, highlight & comment right on webpages.
  • Camstudio is a free screen capture tool that saves AVI and SWF video files.
  • Tinyurl is a web address shortening tool. If you send URLs to people shorten ‘em up with Tinyurl
  • Edublogs is where I do my education blogging. Free blogs have ads, but paid supporters are ad free.
  • Twitter is becoming my communication tool of choice. Love the conversations, and I can still block spammers there.
  • Tweetdeck is an awesome program I use to do most of my Twittering.
  • Facebook is how I keep up with students, family & friends.
  • YouTube is where I post videos
  • Flickr is a place I store & share digital photos online.
  • ShrinkPictures is a cool little website to “webify” your digital photos too big to e-mail or post online
  • Alice is 3-D virtual software that teaches the basics of computer programming, and also lets you make fun, interactive stories
  • Scintilla is a text editor that highlights computer programming and html code. I make most of my web pages with it.
  • Google Docs is a great way to create online documents you can share & collaborate with. Online surveys are surprisingly easy to create. Includes word processing, spreadsheet, slideshows as well.
  • Audacity is an excellent audio editor I love to use.

One tool I would use if I didn’t have Photoshop is Gimp. Gimp is a free photo editing program that is quite popular.

I am sure there are many others I haven’t thought of, but these are the free tools that I use most often. When I need a piece of software and I want to see if there is something free, the first place I look is Sourceforge which is where open source programmers share their work with the world. Check it out, you might find something there you really use and like.

On my wish list is a free non-linear video editor and a free vector drawing tool. Do you know any?

Digital Storytelling & Programming with Alice

Most educators are familiar with Randy Pausch’s famous “Last Lecture.” Far fewer know about his amazing computer learning tool called Alice. Pausch and his team developed Alice as a 3-D virtual world environment that introduces basic computer programming concepts. The best part is you can get Alice from a free download at Alice.org.

Many schools are using Alice as a digital storytelling platform, and the program is within the grasp of even 10-11 yr old middle-school students. Honor Randy Pausch’s memory, and download a free copy of Alice today! Work through the example tutorials, then use Alice to explain to your students how all computers work.

Every computer system, regardless of size or purpose can do these things:

  1. Process Input /Output
  2. Store information
  3. Do repetitive tasks
  4. Make decisions
  5. Do math computations

Alice can also do all of these things. I have put together an overview of Alice which explains each of these five things a computer system can do. You may download and reproduce the PDF for any non-commercial use as much as you like.

I will walk you through this overview at the free Edublogs Online Professional Development this evening (8pm Central Time – 9am Friday, Western Australia time). Feel free to join us if you would like to learn more.  Use this link to join in the discussion.

***Edit***

A couple of resources for those of you interested in using Alice.

  • Dick Baldwin’s tutorials were immensely helpful to me in getting started.
  • Alice cannot record it’s video, so I use CamStudio to capture video from my screen to disk. It’s free.

Making a Wireless Router Act Like an Access Point

Filed under Technology Education

***Warning*** this post is pretty geeky. I wrote it so I might refer back to it if needed, and also if someone has a similar problem they are trying to solve. (If my students see my awesomeness in the process, that is another acceptable outcome ;-)

I got to blow the dust off of my networking skills a little bit today. I teach an introductory networking course and I used to be a system administrator/networking pro, but honestly my skills get a little rusty if I don’t put them to the test once in a while.

Sometimes my networking students wonder why I make them do labs where they must manually configure all of the TCP/IP settings when DHCP will do it automatically. Without knowledge of how to set things up manually, I would have been unable to solve a real-world problem today.

What I thought would take me an hour wound up taking nearly 3. Terry, down at the hardware store, asked me to hook his laptop up to his store’s network using wireless. Terry’s always so willing to help out Wendy & me with stuff that goes wrong around our home (most recently it was the lawn sprinker system), I was hardly in a position to refuse. I had already taken the day off for jury duty and I didn’t know when I would have time otherwise, so I agreed to look at it this afternoon.

The first hour was spent just figuring out what he had, and learning circuitously that the wireless router wasn’t configured & working as expected. (Hmm, I might have thought to ask about that part up front!) He could always get the Internet to work through the wireless, but he couldn’t see the store server, where his merchant programs & data reside.

He already had a router connected to the DSL, and this wireless router was really overkill. All he needed was a simple wireless access point. And that was what I struggled with for quite a bit longer than I should have. The router created a separate network, and was preventing access to the store network through it. How could I make the router act like an access point?

My final solution was to configure the wireless router in this simple manner:

  1. Set the WAN side to Autoconfigure with DHCP and leave it disconnected.
  2. Configure and connect the LAN side to the store network.
  3. Configure the laptop with a static IP also on the store network.
  4. Enable security settings.

Setting things up this way, we bypassed the routing part, only utilizing it as a wireless access point. I spent a lot of time looking for settings in the D-link router config to try to disable routing, but found no such option. Once I figured out that I could get away with hooking up only the LAN side of the router, and the laptop would still talk to it, I was set. Initially, I tried letting the laptop use the router’s DHCP, but when I did this, the laptop was configured to think that the wireless router (which wasn’t connected on the WAN side) was the gateway to the Internet, so the Internet wouldn’t work. The workaround was to use a manually configured IP with the correct gateway address.

It took a lot longer than it would have back in my glory days of networking, to be sure, but it’s good to know that once the cobwebs are blown out, I can still solve real-world networking problems from time to time. I never wanted to be one of those “theory only” professors anyhow. Hopefully doing little projects like this will ensure that I am always able to function in the real world as well as in classroom or laboratory.

Apollo Documents Digitized

Anyone who does any kind of research knows how far we have to go towards digitizing printed collections of documents. Last spring I did a research project at the Eisenhower Presidential Library and was surprised to learn that there are no plans to digitize anything from that important collection in the near future due to a lack of funding.

My ears perked up recently when I learned that the Forsyth Library at Fort Hays State University has been working to digitize the Apollo document collection of the Kansas Cosmosphere. This video is from the press conference announcing the online publication of documents from the Apollo 1 accident investigation which once belonged to Jack Swigert and were given to Charlie Duke who donated them to the museum.

Anyone interested in NASA history and the Apollo space missions should check out the online documents here: http://www.fhsu.edu/forsyth_lib/digital/space/

Federal Aid to Education

This spring I have been researching about the origins of federal aid to education—the National Defense Education Act (NDEA) of 1958 in the Eisenhower Presidential Library. If you care about No Child Left Behind, whether you agree or disagree, you should know that all federal aid to education including NCLB can be traced to the original federal education funding of NDEA in 1958.

Because the launch of Sputnik spooked the American public, supporters of federal aid to public schools were able to get the ball rolling by tying school funding to a perceived national crisis; thus the National Defense Education Act was born.

Not everyone bought into the need for federal funding for schools. For instance Sen. Barry Goldwater wrote the following brief opinion about the NDEA:

This bill and the foregoing remarks of the majority remind me of an old Arabian proverb:

If the camel once get his nose in the tent, his body will soon follow.

If adopted, the legislation will mark the inception of aid, supervision, and ultimately control of education in this country by Federal authorities.

To continue the precedent of state and local control, and to ensure its passage, the law was very explicit in ensuring that the federal government would have no control over public schools.

Sec. 102. Nothing contained in this Act shall be construed to authorize any department, agency, officer, or employee of the United States to exercise any direction, supervision, or control over the curriculum, program of instruction, administration, or personnel of any educational institution or school system (National Defense Education Act of 1958)

Indeed the law did pass when President Eisenhower signed the bill. Here is the statement he made at the time:

You will notice that Ike was also a strong supporter of decentralized control of schools. He notes that the NDEA was only intended to be a short-term remedy to a national crisis when the nation needed more scientists and technologists, with a planned end for the program after four years.

The NDEA did have the intended effect, spurring great strides in math & science education. America ultimately did land a man on the moon, and survive the threat of the cold war.

Kansas primary school students studying science with hands-on experiments.

Kansas High School students learning “Binary Numbers,” the basis upon which digital computer work.

However, since 1958 federal aid to public schools has remained a steady part of the public school landscape—but the original hands-off, decentralized control aspect has become a distant memory. Under federal direction, our schools have become focused upon narrow standards, primarily in math and reading. When I asked my daughter’s teacher about the science that they do in first grade this year, he told me he that the time available is limited because of the push for testing in math and reading.

Also interesting, my daughter recently mentioned to me that her “painting shirt” was wasted this year because they didn’t get the paints out even once this year! This is not a complaint against her teacher at all. He does an excellent job. I spent a day watching him work, and I may go back again soon if I can work it into my schedule before school lets out. But this is a very strong complaint against a system that I believe is headed down the wrong path.

I’m not worried for my daughter. She lives in a very enriched home environment. We think about and talk about a broad variety of things at our house. I am worried for the kids who don’t live in such a place, who depend on the school to provide an excellent, broad education. All of the focus on the testing and accountability isn’t heading us in the right direction.

I know plenty of people think the same way. But what can be done when all of our schools are dependent upon federal dollars to operate and those federal dollars come with strings attached? I wonder if the congressional leaders who voted in 1958 for that first NDEA law could see where we are today, would they have still passed the bill that ultimately changed the way American schools operate?

Hutchinson Travel Bloggers Fam

I am writing this from the fair city of Hutchinson Kansas. Progressive leadership in the community is responsible for organizing a tour for travel bloggers to visit and write about the exciting things that are going on here.

I was late to the party tonight because of class obligations, so I didn’t get to meet everyone yet, but I’m told there are bloggers here from Oklahoma, Illinois, California as well as Kansas.

I did make it in time to see a special screening of the IMAX film, Magnificent Desolation. Amazing film, and I kept thinking how much my daughter Science Girl Em would have liked this show. The film included shots of the Cosmosphere’s lunar lander & lunar rover. (Hopefully tomorrow I’ll be able to make some photos of those.)

The Kansas Cosmosphere at night. Not just every window you look into has both a space shuttle and an SR-71 Blackbird visible.

In the IMAX projection room. Large format 65mm film being loaded

The IMAX sound system has a digital sound track stored on a computer hard disk, and a backup sound track on a magnetic system stored on 35mm film.

The SR-71 Blackbird is on permanent loan from the US Air Force.

A full-size replica of the Space Shuttle Endeavour.

The short time I have been here, I’ve been made to feel most welcome and the group of bloggers is a spirited bunch. I’m really looking forward to see what tomorrow has in store for us.

First Year of Blogging

I can’t believe it’s already been one full year of blogging for me. The experience has been beyond my expectations. According to the Clustrmap I put on shortly after starting this blog,17,381 visitors from around the world have dropped by. This is about 17,000 more than I expected might come by in my first year… THANK YOU!

One of the more interesting things to happen to me recently that relates to this blog is receiving an invitation to Hutchinson, KS on April 15. The community seems to be rather forward thinking, inviting bloggers to experience the sights & sounds of the town to help get the word out. Highlights include the Kansas Cosmosphere, food, a trip to the Amish town of Yoder, and the Kansas Underground Salt Museum. I suspect my blog surfaced on the list of potential interested bloggers because I have written about science and Kansas attractions dealing with science. It has been a while since I’ve been to the Cosmosphere (I saw the Apollo 13 space capsule there last time) and I’ve never been to Yoder or the Underground Salt Museum.

Anyway, I have come a long way from my initial views of blogging. I have learned it isn’t all about me; it is about the conversation I can have with other teachers from around the world, sharing thoughts & ideas.

The blog has given me a nice repository of my own thinking over the past year. Many times I have referred back to it to recall what I was thinking about on a given topic. Even if no one else gains anything from my keeping this blog, I help myself in that regard.

Anyway, I want to thank everyone who has supported and encouraged me over the past year. This has been an amazing experience and I look forward to continued learning & sharing with all of you.

Amazing Grace Hopper

I try to tell all of my female computer students about Grace Hopper, especially those who question the decision to be computer professionals. Too many people do not realize the amazing contributions of women to the field of computing. It is seen as a men-only club, which simply is not true. Some of the best computer people I know are women.

The picture in this post is from 1985, the year that Admiral Grace Hopper and Seaman Recruit Bill Genereux served together in the Navy. I never met her but that was the first year I learned about her.

Yesterday was Ada Lovelace International Day of Blogging. I wrote about another pioneer, Jean Jennings Bartik, who actually worked on the ENIAC and other computer projects before Grace Hopper. Literally hundreds of blog posts were made about women in technology yesterday. Check them out!

Jean Jennings Bartik

Filed under Technology Education

To celebrate Ada Lovelace Day I would like to tell you about Jean Jennings Bartik. I had the pleasure of meeting Ms. Bartik a few years ago when she was speaking at a CCSC computing conference at her alma mater, Northwest Missouri State University in Maryville, Missouri, USA.

Bartik was one of the world’s very first computer programmers— she worked on the original digital computer, the ENIAC (Electronic Numerical Integrator and Computer).

Programmers Betty Jean Jennings (Bartik) (left) and Fran Bilas (right) operate the ENIAC’s main control panel at the Moore School of Electrical Engineering. (U.S. Army photo from the archives of the ARL Technical Library)

The word “computer” originally was not about a machine, it was a job title for a human being. “Betty” Jean Jennings Bartik was hired as a human “computer” by the US Army after graduating in 1945 from Northwest Missouri State Teachers college. Her major was Mathematics, which at the time was an unusual choice for women. She was the only female graduate in Math from the college that year.

Her first job with the Army was computing ballistic range tables for artillery guns. (When I was a Navy Firecontrolman, I had first hand exposure to such range tables. Here’s an example range table for  5″/38 guns like we had on the Battleship Missouri.) Imagine a large telephone book sized document listing all of the possibilities for where a projectile would land with a given initial velocity and a particular angle of elevation. Each calculation was made by hand, since there were no calculators or computer spreadsheets to help do the Math. Day after day, recording page after page of these numbers, that was the sort of tedious work she did for the Army.

She found the work quite monotonous and uninteresting, which is why she jumped at the opportunity to work for a new “secret” government project without knowing exactly what she would be doing. So that is how the girl from Missouri wound up becoming one of the world’s first computer programmers. Instead of doing the ballistics calculations by hand, she would be working with the team learning to use the new ENIAC computer which would ultimately do the same job a thousand times faster than a human computer could. According to the January 2009 issue of the Communications of the ACM:

There were no manuals or instruction guides for programming the ENIAC, which included 17,468 vacuum tubes, occupied more than 680 square feet, and weighed 30 tons. Instead, Bartik and her five female colleagues—Kay McNulty Mauchly Antonelli, Betty Snyder Holberton, Marlyn Wescoff Meltzer, Frances Bilas Spence, and Ruth Lichterman Teitelbaum—pored over its logical and electrical block diagrams and discussed design details with the male engineers and physicists who had created them. Ultimately, the women figured out how to set ENIAC’s 3,000 switches and hundreds of connection cables so calculations would progress correctly
through the complex machine.

That’s right. No manuals or instructions; not even a keyboard, not even punch cards! The machines instructions were hardware encoded directly into the circuitry with switches and cables. English-like computer programming languages would come later thanks in no small part to the efforts of another female computing pioneer (and fellow Navy veteran) Rear Admiral Grace Hopper.

Jean also later worked on the BINAC and the UNIVAC computers. In 1997, Jean and her fellow programmers were inducted into the Women In Technology International Hall of Fame. Jean was given an honorary doctorate from Northwest Missouri State University in 2002.

I remember enjoying her talk very much, she has a great sense of humor, and just tells it like it is. When I had the chance to meet Jean Bartik briefly and get her autograph, I told here about my Navy gunnery experience, and that I’m a college computing teacher. Knowing I am a professor, she wrote to me this very funny note:

Teach women that it is fun. I mean Math and Science. – Jean J. Bartik
