So why do we need CS Principles

| 0 komentar |
I have been asked a lot this past year about why CS Principles is being developed.

Even though computer science is all about change, and the changes in our field seem to zoom by at lightning speed, there are some core ideas and well, principles, that are central to understanding how they work.



For those of us in the AP Computer Science community we do a great job of delivering computer science education. We all can point to students we have launched into the world. These students have overcome obstacles and are working and creating jobs in all sorts of places.

Sadly, this is not enough.

The existing computer science curriculum in K-12 schools does a good job for the few students it reaches, but what about everyone else? Think about where you are....how many schools around you have computer science? How many students in those schools have access to the classes?

Really, how many kids in your community even know what computer science is?

For me it is a question of literacy. To be a productive person you must be literate in the tools society is using to drive change. For that past few centuries this meant reading and writing. While these skills are still necessary for students, understanding computers and technology has become the new marker of literacy.

Simply put, anyone that does not have a foundation in computer science will not be as prepared for the changes to come.

This does not mean that every student needs to master computer science. There will always be a need for a core group of programmers that have reached a master level of understanding. These are the people that, to quote Virginia Tech, invent the future. We need more of these people. We also need these people to reflect the needs of the larger community they serve through their innovation.

And for everyone else? The computer is the tool of the future. We communicate, learn, work create...all with computing devices. To use them well means understanding some fundamental things about how they work and what they can, and cannot, do.

Think about Mr. Rodgers - "these are the people in your neighborhood". How many of them could do their job without a computer? How much of their daily life outside of work- communicating, playing, making, could happen without a computer?

Often in media computers are presented as magic. The character pushes a button and poof - the problem is solved. Those of us in CS know this is just slight of hand. Behind the scenes someone created a tool on a computer to solve the problem.

So this is why we need the CS Principles course. Every student in America needs a rigorous preparation for their future. That preparation must include computer science. Without access to computer science we run the risk innovation looking like magic, only available to those that know the trick.

Last week the CS Principles Phase II piloters met in Chicago. This is a great group of folks working hard to design the curriculum for this new computer science course. I have been so lucky this year to be a part of this community. It has been tiring, frustrating, humbling...and all totally worth it.  Hopefully after this year we have all pushed the rock a bit farther up the hill.

Everything you need to know about CS Principles. This page has all the documents that frame the course. One easy place for all the information.

Take a look, ask some questions. It is time for us as a community to really start the conversation on making the change happen.

Vocabulary Internet Safety

| 0 komentar |


After watching the video on some of the vocabulary words, please continue working on your Internet Safety project.

One caution I would highlight - we seem to be having issues with students who are using Chrome.  Usually what happens is there is a window that pops up asking you to allow or deny something regarding GoAnimate!...and then you are unable to choose either (in other words your computer basically locks up).  So, I highly recommend that you choose to use either Firefox or Safari in order to avoid that happening.  When this does happen you will not be able to save your information - Im sure youd hate to do 30 minutes of work only to have it not save because this window pops up.

What Holds Girls Back from Computer Science an update

| 0 komentar |
A few weeks back I blogged about an infograpfic that was making the rounds.

I am so happy to say that the infographic has been updated:


Better, no?

I am so glad to see the update. Gone is the one of blame and the factual errors about the APCS exam. The whole tone reflects their stated purpose of "Teach Girls To Program Before People Tell Them They Cant Do It". Great approach.

I really love that they now include information on stereotype threat. Joanne Cohoon at UVA has done a lot of great work on this as it relates to females in computer science. It is her research at NCWIT the reference at the bottom.? And while we are at it, have you been to a Tapestry Workshop? If not put it on your list for next summer, absolutely will change your teaching. Resources from past workshops are posted on the site, so you can read ahead,

Well done!

Writing in the Computer Science Classroom

So, you think you are not an English teacher? Guess again.

Disneys Paperman 
This is a good article about the new Disney short film Paperman.  Well be using this article as a prompt in the CS Principles class this week. In making the short Disney combined traditional hand drawn animation with the CGU technology with a piece of software called Meander.

For the CS Principles Pilot this year the focus is on assessment - how will Collegeboard test the kids at the end of the year?

One major change from the existing AP Computer Science course is the addition of written portfolio items. You can preview them here under Prototype Items. Students are asked to write to demonstrate learning in the CS Principles class.

The best way to prepare for a written assessment is to write, go figure. So though out the course I have the students respond in discussion boards and journals. My goal is once a week. Just like with coding frequent practice leads to mastery.

It has been very interesting to see the students reactions. In the pilot class I have a wide range of abilities. Some are seniors taking mostly IB and AP classes, others might not take a single advanced class while in high school. From all the computer science teachers I talk to this is pretty typical. It means that we cannot make assumptions about the students writing levels.

One thing I learned last year was I had to be very explicit about what academic writing should look like. While they have all written English papers, it doesnt always occur to them that rules like "write in full sentences" apply in the computer science class.

We finished up the first Portfolio papers right before winter break. Since the Internet Unplugged is the second unit I cover int he course we did the Internet Portfolio paper. Well be doing the ones on data and programming over the next two months.

Ill summarize more about the Internet Portfolio papers and the experience of working on them with the kids later. Right now I am just trying to come up with enough interesting discussion board topics to keep them writing until the next round.

Crossword Puzzle Learn apostrophe hyphen and quotation marks

| 0 komentar |
Today you will be receiving a crossword puzzle that will be due this Friday.  This crossword puzzle contains vocab words from vocab lists 1 through 3.  This is a homework assignment - you will not receive class time to complete this.  Additionally, you are welcome to turn this in anytime before Friday, but it must be turned in no later than Friday to earn full credit.

Today we are going to learn 3 new symbols on the keyboard, but youll only be learning 2 new keys.  The apostrophe (R4), the hyphen (R4), and the quotation marks (Left Shift + R4) are the new symbols.  As you will notice from above, you also will be using your right little finger on all three of these symbols - its going to get a workout today!

Just to give you an idea of where we are going - tomorrow we are going to start our Internet Safety unit.  When we work on Internet Safety you will be working on a website to create a short video.  The website will require a username and password.

After the Internet Safety project we will head back to learning the ten numbers across the top of the keyboard and the symbols on the numbers.  That should get us pretty close to the end of the first 9 weeks of second semester.
