The 2014 AP comp sci FRQs were seemingly a departure from past exams. Here are my solutions:
Above is a demonstration of harmonic motion using the game physics of Portal 2. I think the motion is more likely a general harmonic oscillator than a simple one but you get the idea. Yes, I know I made a grammar error in the annotation. Meh…
We spent a few days of the spring semester 2014 in AP/IB physics C/HL working on creating puzzles (game levels) for the game Portal 2 using the educational version of Portal 2.
The goal is to show that some element of physics either works as expected or does not by actually collecting some in-game data and analyzing the results. Individuals and small groups spent time learning the game mechanics, learning the basics of puzzle making (game-level design), and then learning how to test out physics ideas by collecting data. Then finally each group or person created an IB-physics-style lab report and we did a day of show and tell.
I got SO much help from Cameron Pittman at Physics With Portals including advice on capturing in-game video, lots of great examples of how to teach physics with Portal 2, and some hints and tricks on collecting data in game. Thanks Cameron! His videos are also really great for anyone interested in teaching physics with Portal 2.
Below is each level in a short video demonstration.
This one was just too crazy not to include. There was no associated paper. Just insanity…
Summary: Learn the basics of screencasting for teachers. This is a common idea in the flipped classroom model.
If you are considering attempting to flip your classroom so you can be more interactive in class and have students get some short and sweet direct instruction at home for homework, at some point you may want to be the one doing the talking for that direct instruction. Some educators use TED talks, MIT OpenCourseWare, Khan Academy, YouTube content, or other teachers’ videos.
If you want to make your own lectures for a flipped classroom, you’re going to need to record content and get it online. Then of course you have to get students to consume your content. This post is all about HOW to make your own content for such a purpose. I’m going to use the term screencasting which has come to mean recording yourself using your computer. You can have your voice over the interactions with applications on your computer and you can also have a video superimposed on the computer.
Software for screencasting ranges from expensive to free and quality varies a lot as well. If you have been in education for a while the name Kathy Schrock is likely familiar to you. She is one of the most prolific educational technology folks around. She has an entire section of her “Schrock Guide” dedicated to screencasting info including links to software downloads and HOWTO articles and videos. You can find info about software, web sites, mobile apps, and pedagogy stuff as well. It’s great.
I bought ScreenFlow a while ago for around $100 which is a lot to spend really. I justified the expense since I do a bit of distance education. The software lets me post to YouTube and Vimeo and add a lot of cool things to the videos. Here is a screencast about one of my recent lessons where screencasting was important. ScreenFlow has been a great tool for me. There are free and cheaper apps out there that do awesome stuff too so don’t think you need something expensive to screencast.
If you are a SMART Board user, then you are in luck. There is an app that’s part of SMART Tools called recorder which can record your actions on the SMART Board and can even record your voice. You can use the SMART Recorder without being connected to a SMART Board nor do you have to even use SMART Notebook. Here is a HOWTO video on using the recorder application. It works on a Mac as well. I tested it out. 🙂
Welcome to the 2013-2014 academic year y’all!
I am going to attempt some very different techniques with all my classes this year.
For my Bellaire classes, I plan to use Edmodo for communication and some assessments. That means students will be expected to create and use an Edmodo account. Go to the respective class homepage for a link to Edmodo
The first place you should go to access files and get notes will be JimmyNewland.com. In fact you can get to my email or Edmodo from here.
How to be prepared for class:
Everyone: There will be many times that having a laptop computer in class will be beneficial. Safety and privacy are issues that each student and her family will have to work out. But in room 186 we will foster an environment of responsible and safe technology use. There will be access to power, ethernet, printing, and wifi (if possible). No one at Bellaire however will be held responsible for the equipment. Students use their own tech at their own risk.
AP Physics C: bring a working pencil, pen, and calculator everyday. You will be working in groups very often as well as taking copious notes. You need a spiral bound notebook or a binder. I also recommend engineering paper instead of regular notebook paper. There are also many handouts you will be responsible for managing. You will be better served to bring your textbook home than to bring it to class everyday.
AP Computer Science: bring a working pencil and pen everyday. You will be working in groups very often as well as taking copious notes. You need a spiral bound notebook or a binder with plenty of paper. You may bring your own computer at any time. Just be aware of the above caveats. There is no physical textbook for computer science. There are however many handouts you will be responsible for managing.
The main goal is to use technology to allow students to learn in a variety of ways and to have access to content at times besides during the school day. Peer-instruction, quality group work, inquiry-based learning, and a general sense of academic awesomeness are my targets.
Summary: Using HTML5 and CSS3 is the most bang for your buck right now if you want to use semantic web ideas in the most broad way possible and Codecademy.com is the best way to learn them right now. Card sorting is a common user interface (UX) technique for websites.
I recently met with a group of law librarians at the South Texas College of Law to discuss a little information architecture theory and practice. The coolest thing about putting together something like this is how much you polish your own skills. I can attest that the best way for me to learn a thing is to attempt to teach it well.
Information architecture is a way of measuring, modeling, and quantifying information as an entity and how humans and machines interact with information. There is a long and illustrious history and the disciplines touched by the ideas here are as varied as librarianship and physics can represent.
How we design the web impacts how we interact with the information therein. I came up with the following claim: When it comes to the web, you get the most bang for your buck in terms of using information architecture by learning to use HTML5 and CSS3 effectively.
HTML5 Makes the Web Better with Semantics
HTML5 has been a long time in the making. The W3C is in charge of putting the official stamp on a finished product. As the more nerdy among you probably know, the father of HTML and Web is Tim Berners-Lee. One of his original visions was to create a web of machine-readable information where the data ABOUT the data would help the machine parse things out. The semantic web isn’t fully realized with HTML5 but you can use HTML5 to add metadata to web content. Let’s look at an example (modified slightly) from the excellent HTML5 Doctor site.
The new HTML tag here is article. So what’s new? Well all the stuff from line 8 to line 29 is one thing. This unit is suitable for export to RSS or ready to be visually set apart from other articles or all setup to connect the time and comments directly to the content via the tags.
Big idea: good metadata makes for a more flexible web!
HTML 4.01 didn’t have this kind of ubiquitous metadata. There is a very similar tag called section which is a more generic way to break up data but the article tag is less ambiguous.
HTML5 isn’t fully baked
HTML5 isn’t exactly finished yet but that hasn’t stopped the web movers and shakers from making this the new standard. You can see how well your particular browser understands HTML5 over at HTML5Test. And yes even Internet Explorer version 10 speaks some HTML5.
Learn to code HTML5 & CSS3
If you want to dig in a bit more you could download the HTML5 boilerplate code, read the free Dive Into HTML5 book online, visit the HTML5 Doctor for some clear explanations of tags, or try out the W3Schools HTML5 lessons.
But one cool and very interactive way to get some HTML5 under your belt is to step through the web fundamentals lessons over at Codecademy. The code you learn isn’t necessarily the most cutting edge HTML5 but what you see there will work across browsers. There is also a cool editor and hints along the way. The lessons culminate in a little product you are to create. It’s a lot of fun! And you can also learn programming fundamentals as well, not just web code.
Card Sorting Can Improve UX
UX and usability has really grown into a mature field of study within information architecture. I recommend taking a stroll through some of the great work over at the Norman-Nielsen Group site to get a feel for how much analysis goes into how humans interact with the web.
Big idea: Card sorting can allow the stakeholders to shape the UX of a site.
One easy to implement idea is card sorting. First find a group of stakeholders in the web project in question. They need not be web designers. Then ask them to write out on cards the topics that are most important to have on the website. There are a lot of ways to use this sort of mental inventory. You can sort them. You could ask another team to put them in piles and turn those into your menus. Or many many other things. You can also use software tools to a similar end by using a web-based card sorting tool. I also found some unrelated but cool mental map tools out there!
