CSTA Leadership Gets Busy for CS Ed Week!

Did you see this on the CSTA mailing list? When the CSTA Board met recently we started talking about sharing what we were doing in our schools for Computer Science Education week. It’s not all about the Hour of Code – cool as that may be. The result of our conversation was this video recorded during breaks in the meeting 

Watch our latest video to learn what the CSTA Board Members and Task Force Chairs will be doing for CSEdWeek 2014, which coincides with Grace Hopper's birthday. From a Humanitarian Hack-a-Thon to a Birthday Party Open House, these activities will be sure to get you thinking about the engaging and inspiring programs you can host at your school

Interesting Links 24 November 2014

This will be a short week in school. Thanksgiving is Thursday in the US and my school is off for a five day weekend. I’m looking forward to a bit of a break. I think my students are more ready though. Smile Well let’s share some links.

Weeks of programming can save you hours of planning. This is the most retweeted and favorite tweet I’ve done in a while. Wish it was unique to me but the saying has been around for a while. The other CS teacher at my school has this on his lab wall. It’s going up in mine as well.

Shakespearean Insult Generator - an interesting project in Python by Simon Johnson @clcsimon. I’m working on doing this with my C# students in C# of course.

Seeking study participants: What should BS in CS graduates know about software development? I believe she is looking for people from industry (hiring managers) to reply.

Check out the CS Participation Kit and get inspired -- during CS ED Week, December 8-14, or any time of the year!

The call went out for Computer Science Teachers Association 2015 Board of Directors Nominations. I’m planning on running again. We’re always looking for good candidates though.

How to Not Drive Students Away from CIS my friend Randy Guthrie takes on this tough but important topic.

Little evidence to believe 10x programming productivity gap. Doesn't matter. It's an education problem. Great piece by Mark Guzdial.

Nice article by Pat Yongpradit. Should we teach computer science in elementary school? My vote is pretty clear.

TouchDevelop on Student Devices

I have this sort of love/hate relationship with web based applications. I had reason for a bit of both today. I like to introduce students to programming using TouchDevelop which is a web app for most people although there is a really nice Windows Phone app for it as well.
Today, for some reason TouchDevelop would not load properly on the student computers in my lab. I'm not sure why as it loads fine for me on the same computers and it has worked fine in the past. I suspect a network glitch.
Regardless, about half the students pulled out personal laptops, tablets or cell phones and asked if they could use those. Sure, why not?  It was very cool seeing students work on the exercise on all different devices and having success. I think that some of the students enjoyed the experience more using their own devices than they would have on the computers. Sure the computer screens are larger and that makes things easier (for me at least) but this make the exercise more personal.
I may make that the default option (using personal devices) in the future. We’ll see how it goes.
FWIW the web app we created in class today can be found at https://www.touchdevelop.com/nwgf

[Edit: Everything worked just fine the next day. A number of servers were rebooted and that seems to have cleared a number of network issues.]

Top Secret Rosies

This week I have been showing the movie "Top Secret Rosies" to my freshmen students. It’s a wonderful story about some long unsung heroes of both World War II and computing. As introduced on the related web page:

In 1942, when computers were human and women were underestimated, a group of female mathematicians were recruited to complete secret research for the US Army. Top Secret Rosies: The Female Computers of WWII is a one hour documentary that shares the little known story of the women and technology that helped win the war and usher in the modern computer age.

I show this movie for several reasons. An obvious one is to show how women have long been involved in computing. Their role has been ignored far to often. The students, not surprisingly the girls especially, notice how women were not given full credit for their work at the time. This is a great starting point for conversation. I want my students to understand though that women have and continue to contribute important things to computing even when men are getting most of the attention.

Another, perhaps less obvious, reason is to help students realize how important the software is to the hardware. When I hear students, mostly male this time, talk about the hardware specifications of computers, tablets and cell phones I realize their don’t really appreciate the importance of the software that makes those devices useful. The movie highlights how important the work of these pioneering women was in making the computer actually useful. I also like how they talk about the women debugging the hardware by knowing the complete system so well.

We often talk about Ada Lovelace and Grace Hopper when we talk about the history of computing and software. These are important people but there are more women we can talk about and show as examples for all of our students.

Interesting Links 17 November 2014

Last week was crazy for me. Professional development day last Monday and Veterans Day on Tuesday just made things start differently. Friday was a travel day as I flew out to Tucson AZ for the CSTA Board meeting. CSTA members you have some great people on the board (and me too). We had a great couple of days worth of meetings.

I spent less time on the internet than usual. You may have noticed blog writing has been less lately. But I do have a few links to share anyway.

Great "Faces of Computing" contest due Nov 20 2014. Still some time to get student entries in.

This Binary number game from CISCO can be addicting. It’s one of the resources listed on my Resources For Teaching Binary Numbers blog post. Someone tweeted about it and set me off playing for a while. So I thought it worth a reminder to others.

Have you been to the Summit? a report on the AP CS Principles summit that was held this past summer.

Computing Is The Safe STEM Career Choice in 2014 is an interesting article at the  blog@CACM | Communications of the ACM.

ACM's Turing Award Prize Raised to $1 Million – This is great news for this award. The Turing Award is the closest thing to a Nobel Prize in computing. Google is putting up money for this which is create. I’ve already seen enhanced news coverage of this award.

Dear Senator Ted Cruz, I'm going to explain to you how Net Neutrality ACTUALLY works  from  The Oatmeal who gets serious for a change. This is an issue I’ve been having my students discuss in class.

Microsoft takes .NET open source and cross-platform

I'm still trying to wrap my head around this.

Microsoft takes .NET open source and cross-platform, adds new development capabilities with Visual Studio 2015, .NET 2015 and Visual Studio Online

Initially this feels good for me. I like Visual Studio and .NET. Specifically Visual Basic and C#. I wonder how this is good for Microsoft though. I also wonder how much development will actually take place on .NET with it being open source. Is this throwing .NET away in reality?

The announcement linked to above says that Visual Studio 2015 is “[b]uilt from the ground up with support for iOS, Android and Windows” And I see that the new Visual Studio has an Android emulator so there is that. There is a lot more to read about this move. And we’ll have to see how soon and how well the promised cross platform software develops and makes it into the wild.

In the mean time I am installing the Visual Studio 2015 Ultimate preview so I can start trying things out.

What does this mean for education? That’s the big thing I want to figure out. Initially it suggests that schools teaching using .NET languages can easily move to mobile development not matter what mobile platform them want to use without having to pick and teach several development tools and languages. And Apple Mac schools can now use Visual basic which I still believe is a wonderful first language for teaching.

What else? Still trying to figure that out. I didn’t get any heads up on this so I have no idea what the message for educators will be.
