Code in Different Languages

The other day I found an older blog post by Rob Underwood called Code Syntax Compared. In it he wrote a very simple program in 5 different languages. He used Python, Ruby, JavaScript, PHP and Java. No .NET languages. So since I was interested I wrote samples of the same program in C# and Visual Basic. Hey why not.

The most interesting thing to me is the typing. That is to say that some of the languages that Rob used are dynamic type languages while Java, C# and Visual Basic are statically typed languages. Which is better? Well like so many things in computer science – it depends. There is a good paper (the link is to a PDF)  on the topic - Static Typing Where Possible, Dynamic Typing When Needed: The End of the Cold War Between Programming Languages by Erik Meijer and Peter Drayton.

Anyway, if you are curious my samples are below:

Top Posts from 2015

I decided it was time to take a look at my most read posts from the last year. This is an interesting exercise for several reasons. One is the inconsistency of statistics. I have two sources (Google Analytics and Blogger’s native statistics) there is not as much similarity as you would expect. Certainly not as much as I’d like. Another reason is that most of the most  widely read posts were not posted originally in 2015.  Search engine traffic brings a majority of my readers. But for good or for ill, accurate or not, here is what appear to be the most read posts over the last year.
Programming With Blocks  First posted three years ago but updated regularly since. A lot vof people seem interested in this topic.
Recursion – Love it or hate it? Posted this year back in February.  I guess I am not the only one who struggles with this topic.
Interview Questions for Computer Science Teachers A surprise. I wrote this list in March, with input from many people, after I saw that people were searching for related questions.
How NOT To Tell If Someone Is Cut Out For Computer Science This was a reaction to something I read online. In it I try to address some stereotypes about who is and is not cut out for computer science.
Lecture, Demo, Project From April of 2013, this post talks about my teaching style. I’ve no idea why search engines bring so many people to it.
Resources For Teaching Binary Numbers Also from April 2013 though I have updated it several times. And always looking for new resources if you know of any. Lots more people seem to be teaching this topic lately. It’s one of my favorites.
Programming Languages for Middle School From December 2013 (I must have been on a roll in 2013) this is another topic that has had a lot of interest this year. I’d love for some current middle school CS teachers to make suggestions for updates.
Robots For Teaching Programming Another list post that is updated as I found new resources. Good stuff for people who would rather move atoms than pixels.
Computer (and Math) Humor From May 2013. The link here is actually to a new version I posted yesterday that has a lot more images.
Your GPA Doesn’t Mean Anything Useful Really some thoughts on grades and what they are and are not good for.
The first three on this list have the really large numbers along with the base address (http://blog.acthompson.net ) I expect them to continue to attract search engine traffic. I’ll try to create some new posts that add value during the coming year though. Thanks for reading.

Computer (and Math) Humor

Two Kinds

I like this one in part because it is subtle. There are two basic standards for opening the curly brace in C-type languages.  Not everyone will pick up on it. Is it important which way you do it? Actually no. It may not even be important if you stick to it. But some people really do insist that their way is the one true way and that everything else is wrong.

Of course there is also the group of people who think that curly braces and semi colons are crutches for compiler developers and that real programming languages don't need them.

lol_programming

I’ve seen this time and again. OK perhaps even felt the same way. When nothing seems to be working programming can be frustrating and even something to hate. But lots of us persist. And when it works it just feels so good.

OK it’s math not computer science. But is sure is fun.

CSTA Board of Directors Election Call for Applications/Nominations

It's time for elections or at least nominations for positions on the Computer Science Teachers Association board of directors. I'm in my third year on the board (and not up for reelection) so I have some ideas about what is involved in being on the board. I thought some might find that useful if they are thinking of running.
The first thing you have to know is that the board is a working board. It is not just showing up for a couple of meetings, hearing reports and nodding appreciatively or perhaps suggestions some tweaks to process. There are two face to face meetings a year. They are generally each two-day meetings. One is held in conjunction with the CSTA Annual Conference. The other, held in November, is held at a fairly central location. I've attended meetings in Arizona the last three meetings. Turns out that is the off season and expenses are kept low that way. There is also a full board meeting via teleconference in the winter.
All members on the board are on several committees which conduct business throughout the year via teleconference, email, and cloud based shared documents. For example the Equity committee runs an annually competition. This involves creating the contest, designing the rules, judging the entries and picking winners. Even with staff help (CSTA has a small but amazing staff) this means real work for committee members. Other committees have their own projects. The nominations and elections committee will be working on collecting and evaluating nominations over the next few weeks and months.
It is rewarding work though. The board is very collegial and people tend to work well together. And of course we are all committed to the mission of the CSTA. If you feel like this is a project you want to take on give serious thought to running.

The following CSTA Director positions will be vacated on June 30, 2016. We encourage interested CSTA members to apply or to encourage other qualified members to submit an application. Late nominations will not be accepted. 

The CSTA Board is a working Board. All Directors are required to attend two face-to-face Board meetings per year (including the combined Board Meeting and CSTA Conference on July 7-12, 2016) and are expected to contribute meaningfully by participating on at least two committees. 

Vacancies: 

9-12 Representative: A classroom teacher who is currently teaching computer science at the high school level.

At-Large Representative: An educator with responsibilities for K-12 CS education.

International Representative: An international (outside the United States) classroom teacher who is currently teaching or promoting computer science at the pre collegiate level.

State Department Representative: An educator or administrator who reports to a state department of education and oversees, in some capacity, computer science education.

University Faculty Representative: A faculty member from a university computing department offering graduate degrees in computer science.

CSTA is dedicated to promoting diversity in K-12 computer science education as well as on its Board. We strongly encourage all qualified individuals to apply. The Nominations and Elections Committee of the CSTA Board will select the two best-qualified applicants in each position for inclusion on the ballot. 

Nominations deadline: January 31, 2016. 

How to submit your application: 

1. Download the 2016 CSTA Nominations Form from the CSTA website at:

2. Complete the nominations form.
The form includes the following information: 
  • Position for which you are applying
  • Your name
  • Address
  • School or employer
  • Current title/Role
  • Email address
  • Phone number
  • Personal statement that explains your motivation, and why you are a strong candidate (limited to 130 words). 
  • Answers to the following four questions (no more than 100 words each): 
    • What experiences and/or interests in K-12 computer science/information technology education qualify you to serve as a leader for the organization?
    • What previous experience do you have with CSTA?
    • What leadership skills do you have that would enrich the Board and the organization? 
    • What do you think are the most important issues fir K-12 computer science education?
3. Submit the completed Nominations Form and your current résumé of experience to the Elections Committee by emailing them to nominations@csta-hq.org. The documents may be submitted in Microsoft Word or PDF format; PDF is preferred. 

Each candidate's personal statement and answers to the four questions will be posted on the CSTA website and included on the ballot. Statements will be truncated at the word-count limit if necessary. The candidate's résumé will not be made public. 

Ballot distribution: The election will take place online, beginning February 22, 2016. All CSTA members in good standing will be eligible to vote.

Voting deadline: The election will close March 22, 2016.

Do You Have Any Duct Tape?

Students this morning were asking people for duct tape. I don’t know what problem they were trying to solve but eventually it was solved with a plastic cup. Really. But it got me thinking about how students ask for help in programming projects. What seems to happen a lot is that they come up with a solution, some action they want the computer will do, that will solve their problem. This leads them to ask how to implement that action rather than how to solve their real problem. The problem for them and for me as a teacher is that the “solution” they have come up with may not be the best or even a good solution.
This can often lead to frustration in the long run as students try to make some feature of a language or library do things it was not really intended to do. I’ve learned to ask “what problem are you trying to solve?” Students sometimes have trouble explaining that as well. So my asking them often helps (or forces) them to think a bit more deeply about their ideas. Once they do that and understand both what they want to do and what the feature they are asking about does they see that they need something different. Or even see how to use a feature more correctly.
In many ways I see teaching programming as pointing students in a direction and getting out of the way. It sounds easy and in some ways it is. At least it is easier than trying to cover everything they could possibly need to know in lectures (which bore everyone). On the other hand it involves dialogue between teacher and student so that there is mutual understanding. I think that this helps students a lot though. They learn to think things out in more detail and learn how to communicate their ideas better. And of course it avoids some (though never all) of the “wrong” directions students run down in their hurry to get things done.
There is value in the “wrong” directions as well. But when you have a limit3ed time to work with students and grades must be given (yuck) and you want to keep enthusiasm high providing some good direction is pretty important.

Technology Changed How I Read

This week I have been reading an old-fashioned paper book. (The Martian – outstanding read) For the last two years most of my reading has been on my Kindle. I love my Kindle. I didn’t realize quite how much it changed things for me until I started reading the “dead tree” book though.

There are a couple of game changers for me in the Kindle. One is the obvious fact that if I read a book that is part of a series and I like it I can order the rest of the books and start reading them right away. A more subtle change though is that the Kindle has a dictionary.

If I run into a word I don’t know, which happens more than I like to admit, I can highlight the work and the dictionary will tell me what it means.

This feature doesn’t seem to exist in paper books. Yes, I find myself wanting to press on a word on the paper to see definitions but it doesn’t work. Silly I know but one gets used to things.

I remember as a child reading encyclopedias which were also paper back them. I would see references to other articles and in a few hours I would have a stack of books as I followed links from one article and book to another. I could do that because my mother worked hard selling encyclopedias so that we could have a set at home. Not every child was so lucky. Today of course we have the world wide web and following links is easy and doesn’t require stacks of books. It’s wonderful for the curious.

I wonder what things will be like when my grandson is my age. Will he just ask the computer for more information and say “tell me more?” Will he virtually walk though virtual corridors looking at virtual things? Or will it be something else again?

PBS KIDS ScratchJr.

Scratch Jr and PBS are both well known entities in education for younger children. It’s probably not surprising that the two have partnered up . Just in time for CS Education Week PBS announced its first coding app called PBS KIDS ScratchJr. From the announcement:

Today, PBS KIDS launched PBS KIDS ScratchJr, a free app developed in collaboration with the MIT Media Lab and Tufts University’s Developmental Technologies Research Group. Available now on iPad and Android tablets, PBS KIDS ScratchJr helps children ages 5-8 learn core coding concepts as they create their own interactive stories and games using PBS KIDS characters. PBS KIDS ScratchJr incorporates PBS KIDS media properties, including WILD KRATTS, WORDGIRL, PEG + CAT and the new series NATURE CAT. As kids snap together colorful programming blocks to make their favorite characters move, jump, dance and sing, they will learn to solve problems, design projects and express themselves creatively.

PBS KIDS ScratchJr Features

  • Colorful Programming Blocks: Snap together the color-coded programming blocks to create sequences of actions that cause characters to animate and interact in fun and exciting ways.
  • PBS KIDS Characters and Backgrounds: Create projects based on PBS KIDS shows and mix-and-match over 150 characters.
  • Paint Editing: Create unique characters and backgrounds.
  • Voice Recording: Use the recording tool to add sounds and give voice to projects.
  • Story Starters: Find inspiration with in-app story starters! Each Story Starter features a different set of characters and is designed to encourage children to edit and complete the story however they’d like.


The app is free, and can be downloaded on the
App Store and Google Play.

Studio K for Kodu

I first wrote about Project K several years ago when it first came out. That was in my old Microsoft blog which I no longer have access to change. Recently I was contacted by the Project K team who told me about new links for their curriculum materials. They worked with the Kodu team at the very beginning and have years of experience teaching with Kodu at this point. So it seemed like a good idea to write about it again with updated links.


What is Studio K?

Studio K is a game design curriculum, online community, and set of teacher-support tools intended to enable teachers to help learners make their own video games using Microsoft Kodu. Kodu is a powerful 3D game design and programming tool that enables users to focus on creating compelling games for their friends.

Thymio–An interesting Looking Robot for Teaching

New things for teaching seem to appear every week. Sometimes they are around for a while before I find out about them. Apparently the world of computer science education does not revolve around me. :-) In any case I recently learned about the Thymio II robot. It’s a bit pricy at around $199 but it seems to have a lot of nice features including sensors and actuators. So I think it can serve as the basis for some complicated projects if that is a goal.
image ThymioTechykids.com is a robot developed in Europe for educational purposes. It provides three main features:
  • a large number of sensors and actuators,
  • an educative interactivity based on light and touch,
  • a programming environment featuring graphical and text programming.
They have a US distributor called TechyKids who also have curriculum.. It is run by a teacher who uses these robots in her classroom.
This is the latest entry to my list of Robots For Teaching Programming which I update as I learn of new robots. Let me know if I am missing any that I should list.

Students are Creative and that is a Good Thing

I love the creativity of students. We worked on a whack a mole game in class today. The purpose was to create a user control but of course students want to do more. Or at least different. Clearly the images I provided are too boring for most.

Several students used pictures of themselves or a friend. Others found other images to use. As you might expect at least one student went and found a picture of me. Yes, “whack Mr. Thompson.” But he was clever about at. He took a standard picture of me wearing my hat for one image. For the other he found an image of a hat much like the one I wear. When the program runs it almost looks like the hat is moving up to show the "mole" underneath.

Another student wanted to add sound. I made him look that up and figure it out for himself. I expect sound to show up in projects from a lot of students in the next few days. That may or may not be a good thing. The jury is still out on that. In any case students do a great job of teaching each other and learning from each other.

Letting students get creative really seems to help them learn. They do more and try more things. They decide to look things up and so learn how to teach themselves. That is more than worth being used in a whack a mole game.
