Lift Ticket Project

Have you bought lift tickets at a ski resort lately? There are a lot of options. Different age groups, different days (week days, weekends, holidays) and different options for how long you will be skiing or which hills you will be on. I can’t imagine any of this working without computer terminals. Well not without having smart people taking time that you don’t want them to take. So obviously this is a good programming project.

I’m working with decision structures with my programming students. I was trying to think of something new to do. Something that would involve if statements with a little complexity and that might I thought of lift tickets. Off I went to the website of a ski resort I have enjoyed (Bretton Woods in NH) and took a snapshot of their rates. The whole thing is more complicated than I wanted for now so I just recorded the weekend rates for full-day, the various age groups and the different prices for resort guests and non-guests. I asked the students to put together a program to ask for an age, resort stay status, and show the price for a single ticket.

clip_image002There are four age ranges not including younger than 5 and older than 79 which are groups that ski/ride for free. Having the two options for each age group almost forces nested if statements. Almost but not quite.

The thing I may like most about this project is that there are many possible ways to solve it. So far I seem to have almost as many different solutions as I have students. Even better – not all of them work in all cases. Our next class is going to involve looking at different solutions and discussing them.

It should make for an interesting class.

We’re into the second semester at my school and things are off to a good start. Although we did miss a day last Friday because of snow. I had my programming students do some puzzles on Code Hunt. They could write and test code in the web browser no matter what computer they have. Winning!
I collected a bunch of good links to share including some I found while staying home from school. Always working. Smile

Microsoft Research Open Source Challenge

Now this is interesting. Not often you think of Microsoft and Open Source in the same sentence. Although it does seem to be happening more and more often. This looks like it is for university students. An internship at Microsoft Research would look pretty good on a resume.


Microsoft Research is delighted to announce its first Open Source Challenge that uses the many and various open source computer science tools from our researchers. From artificial intelligence to programming models, cryptography to education, there is something for every enquiring mind.

See http://aka.ms/opensourcechallenge for full details. Closing date: April 11, 2016.

MSR OSCProfessors – please circulate this email to your students.

Experience the power of open source software from a top research lab.

Join students all round the world in solving problems with Microsoft's open source tools.

Win big prizes, or the opportunity to interview for an internship at Microsoft Research.

An Online Community for CS Teachers Using Microsoft Tools

One thing I am constantly looking to do is to learn from other computer science teachers. There are some good online communities for this purpose. I’m a member of a couple of Facebook groups for example. And I regularly follow conversations on the SIGCSE and AP CS mailing lists. A few months ago I joined an online community for teachers using Microsoft tools to teach computer science.

In the group are teachers using the tools I use a lot – Visual Studio, Code Hunt and TouchDevelop for example. Also some tools I occasionally use but have liked for years like Kodu and Small Basic. And somethings I am still learning about like Minecraft and the BBC Micro:Bit. And more. It is a very friendly and helpful bunch of teachers and I am learning a lot.

If you are using Microsoft tools/products to teach computer science, you’ll want to join. Sign up at http://aka.ms/MCSTN

A Framework for K-12 Computer Science Education

Last week about 25 or so computer science educators met in Austin TX for two days to work on A Framework for K-12 Computer Science Education. This was not the first meeting of course. Meetings have been taking place online and in person for some months now.

The process started last fall with meetings of thought leaders and stakeholders in CS education. (Mark Guzdial wrote about one of these meetings and the start of the process at the BLOG@CACM in Advice for CS Education from Science and Mathematics Education.

With all the attention computer science education is getting these days (finally) it is important that the community have quality resources to work with. This framework (and standards like those that CSTA is updating) are huge parts of filling that need.

A steering committee initially comprised of the Computer Science Teachers Association, the Association for Computing Machinery, and Code.org is overseeing this project. And there are many top CS educators involved.

Of course a project like this needs a lot of eyes looking over things. Transparency is a must. So there will be review periods. In fact, the first review period launches with a webinar (link) on Feb 3 at 8 pm ET / 5pm PT. More information about being involved in the review is on the K-12 CS Framework web site. It is very important that a wide representation of computer science educators be involved in this project. I hope many of you will get involved.
