So What is code

Saturday, November 12, 2016

Great video from PBS Off Book, a series that explores art in the digital world

Is Code the Most Important Language in the World?


 

It does a great job of quickly describing what code is and then delving into some of the current issues in computer science. I am using it this week as a part of CS Education Week as a journal prompt for my students.

"It is hard to say what problems would be solved with a more diverse workforce."
- Adda Birnir, Co-Founder SkillCrush
 This is the driving force behind a lot of my own work lately. This moves is beyond just looking at diversity of the workplace, but really at how we solve problems as a society.

Inevitably the problems we solve are going to reflect the views and experiences of those solving them. At a deeper level though, the people with the ability to solve these problems through coding have the power to ultimately decide what problems get solutions.

Computer Science is predominantly white and Asian males. In the 2010 census this group made up roughly 38% of the overall population in the United States. That means that 62% of the population is outside of this circle of influence. In essence their problems are outside the view of the people solving humanities problems.

I highly recommend the series in general. The videos are very engaging, short, and show a great diversity of people working with technology.

Some other topics they cover:

  • Future of Wearable Technology
  • Art of Data Visualization
  • Art of Creative Coding
And in case you are using writing in your cs classes heres a full list of the Journal prompts I use in CS Principles.

AP Computer Science Report Virginia is for some Coders

Sunday, October 30, 2016


The AP data is out for 2013. Some great increased nationwide. AP Computer Science went from 26,103 to 31,117 total exams given, a 19% increase. This was the highest increase out of all of the subject areas. But keep in mind AP Calculus had 282,814 exams last year, so we have a ways to go.





Virginia had 1655 AP Computer Science  exams with a mean score of 3.12. Last year we had 1430 tests with an average of 2.98. Over the past 5 years there has been an 81% increase in the number of APCS exams given. This year was also the highest mean score for the past five years, so some great progress has been made.

According to the state report card 67,805 students took AP exams in 2013 (data here). So teh APCS exam accounted for about 2.5% of the overall number of AP exams given.

Which all sounds great, until you start to look a little deeper.

When you look, in 2013 the number of black students taking the exam was 3. Our max in the past 5 years was 6. Six. That year my personal AP class was 1/3 of those African American students.

Demographically Virginia is about 20% black. With roughly 375,502 students enrolled in Virginia public high schools last year (2013 enrollment data) that means we have roughly 75,000 African American students at the high school level, and 3 took the AP Computer Science exam.


If we randomly assigned students electives we would have fared better.

And you can look at any of the subgroups and see the same trend. For instance for the 2013 exam 25% of the 8 Hispanic students to take the exam sat in my classroom.

Now Im a big believer at starting with data and getting to the stories underneath. The bottom line in Virginia is access.

For instance, Richmond city schools, a predominantly African American school district has no computer science classes. None, zippo, zilch.

This is not about diversity for diversitys sake. This means these kids do not have access to jobs. According to the Bureau of Labor and Statistics Virginia is 4th in the nation for jobs in this area, but 12th population wise. This means we have the highest concentration of jobs nationwide in computer science. Washington DC and Virginia rank #1 and 2 for salary nationwide - so these great jobs cannot be filled by huge numbers of our children. A child sitting in Kindergarten in Richmond City Schools today may never even know this field exists, literally blocks from the front door of their school

And at a deeper level, computer science is the tool we use to solve human problems. Being the person holding the tool means you get to decide what is a problem and what gets a solution. These numbers mean these communities do not get to participate.

So to change the data, we have to change the stories. Every high school in the state needs computer science classes that are rigorous and relevant for its students. That means trained teachers and a working curriculum. Kids and parents need to know that this is an option for them, that they can create using this tool. They need to be able to tell their stories as we build the future.

A few things to put Virginia in Context:

  • Virginia has not adopted common core
  • Our K-12 end of course tests are called the SOLs (Standards of Learning). Yes, really
  • AP Computer Science counts as a 4th math credit here, but only if you are going for an advanced diploma, and you have passed Alg II. were working on it
  • We are a Commonwealth, which means our school systems are driven at the local level, not by top down policy and curriculum from the state.
  • Out legislature meets either 4 or 6 weeks a year, thats it.

What is Missing from the Next Generation Science Standards

Saturday, June 4, 2016

The Next Generation Science Standards were published on May 11th.




This week the CSEd Week Blog a great post about why computer science should be included in these standards.

From the post:

While the math standards are well on their way to being implemented and assessed, Achieve’s new effort on the science standards is still in development, and they need to hear from you about the importance of having real, engaging computer science in these standards.

HTML is not programming so why teach it

Tuesday, April 12, 2016

So in talking to parents and guidance counselors I occasionally get asked if a kid can jump ahead and take one of our upper lever computer science classes. My first question is always "have they programmed?" Yes, I know, programming is not the end all and be all of computer science, but for a student that wants to take the current AP Computer Science course they need to be able to code.

Sadly the answer I most often get is "yes, they know HTML". Sigh.

For the CS Principles pilot this last year my second unit was The Internet Unplugged.  We covered both the hardware side along with how to actually make a web site. Yes, I taught HTML and CSS.

So the question is - why cover HTML at all?

One of the core themes of the CS Principles course is broadening participation. So many students have had exposure to HTML, and they all use web sites. This is the interface they use to get at the information on the web. It is an immediate way to show abstraction in action.

Plus, as we transitioned to coding students were already used to the idea that formatting and exact punctuation matters. This let us focus on the tools of programming, like ifs and loops.

And of course, CS Principles is not all about programming. The Internet is one of the seven core principles, equal to programming.

So this summer I am reviewing what we did in CS Principles last year. Honestly this was one of the better units we covered. It tied into all of the big ideas and was something we referred back to the rest of the year.

On the other hand I am not crazy about how I taught HTML. It was a bit dry - too much lecture and we got a bit bogged down. Id like to reduce this to just 4 days.

Next year I plan on trying Thimble. This is offered by Mozilla and lets you type in the HTML interactively and see what happens immediately. It also points out errors right away.

Why Code Academy is Awesome

Thursday, March 10, 2016

We have been using Codeacademy in the CS Principles course to cover HTML and CSS (the abstraction part of the Big Ideas). IT is a great tool - lets the kids self pace, give instant feedback. They have made some pretty amazing things.

Plus the site uses badges to track progress. You know how I love badges.



I just got this e-mail from them - such a grreat summary of why Computer Science is important:

You’ve been a Codecademy student for a month now. Well done!

Here’s why that’s great news for you:

We believe that learning how to program is the best job security you can have because it’s more important than ever before to understand the systems we depend on every day.

The need for computer literacy has never been greater. As a Codecademy user, you’re getting a head start in many ways:
  • You’re learning how programs function, and how to control them
  • Programming is a skill that’s virtually guaranteed to help you get a job
  • By learning to code, you’re becoming a creator: someone who makes things happen
  • You can create programs, games, web pages and animations
  • As your coding skills grow, you can share knowledge and even teach your skills to others
  • In a world of tech consumers, you’re becoming an empowered builder…
Nice work!
So don’t stop here. Why not master a topic right now?
Exactly.

Computer Memory is an Important Part of the Computer

Sunday, February 21, 2016

Computer memory is an important part of the computer because it allows it to store vital information that you will need. Whether the information is in the form of data, pictures or sounds, a computer with a lot of memory can store it. There are basic types of computer memory and you will need to know a little bit about each to ensure your computer is running effectively.

Random access memory or RAM is the same thing as your computer memory. RAM is the main memory center, so essentially, it is the most important. The reason RAM is so crucial is that it is used to store your files and programs and it affects many other computer aspects as well.

DDR computer memory can be bought to increase the amount of memory you have, but first you will want to learn a little more about your computer. Understanding how it works will help you work better with your computer.

The more RAM computer memory your computer has, the faster it will work for you. If you find that youre computer has been very slow lately, you might want to look into buying some DDR for it. If you arent sure what to buy or how to install it, its best to let a professional do it this time around. You will find that all electronic stores that sell RAM will offer optional installation services for a small fee. If you choose this option, it would be a great idea to ask them exactly what they did so you can do it yourself if the need ever arises again.
But, if you know a little something already about computer memory, why not install your DDR program yourself? It will save you some time and money and your computer will be back to working at optimal speed in no time. Either route you choose, dont neglect the health of your computer. If it starts working differently than it ever has, get it checked out or troubleshoot the problem yourself. This will ensure that it stays working great for years to come.
