Cross-class Collaboration Projects

Anonymous — Mon, 05 Sep 2011 16:00:16 GMT

Today’s post comes from Daryl Taylor, a high school physics and astronomy teacher in Connecticut. It was originally posted in response to this question on the NSTA Physics Listserv: “Has anyone had students collaborate with another class in a different locality for any class projects or assignments?”

I have, and love to, run collabs with various schools around the world just about any chance I can.

We’ve recently run a parallax project (Astro-based) with a physics class in California; results weren’t great, but made the point.
I run, based on a CIESE NJIT collab project, a “Circumference of Earth” collab any time I can get a school far away and at a very different latitude; results are always within a few %; unheard of accuracy in the Fizzix classroom.
A few yrs ago, we ran a collab with a Forensics class in South Jersey. They were doing a “Who Done It” type of project and they (a teacher I used to work with) enlisted my Fizzix class help. They sent us images of blood spatter and foot and hand prints and the “crime” scene in general. My kids had to research and learn a little “blood spatter” physics, (including enlisting a guest expert from the local police dept!) and submitted their “FBI (Fizzix Blood Investigators) lab report” via PDF files and a Skype session. The Jersey Forensics class then went further and held a mock trial type thing with their Mock Trial Team and we watched as the audience and expert witnesses via Skype. Was great fun and kids (and I) learned the proverbial ton.
Year-long project with another school to build a “self-sustaining human habitat in a locale considered non-habitable”. Kids decided to build a habitat under the Pacific Ocean (I thought the Moon or Mars, but NOOOOooo….) complete with alternate energy sources (including a ‘back-up’ nuclear plant…) and even a specific population hand-picked by the “planning committee”. Really cool. Did a lot of Distance Learning stuff and covered topics that absolutely amazed me.
Also based on a CIESE project, The Boiling Point Project, I try to find a physics and/or chemistry class somewhere at a very high elevation, like Boulder or Denver or Mexico City, to run two collabs at once: boiling point of water and acceleration of gravity. If properly equipped and labs are run precisely, results on both are great. Email, text, and Skype are used to keep classes up to snuff with each other. In fact, each Lab group includes two of my kids and two of their kids so they HAVE to share and collab differently than a self-contained classroom situation.
I’ve even just taken a basic high school lab like diffraction and ran a collab (Co-Lab, get it? I crack myself up….) with another school just to get twice the data and more worthy results. Also gets kids involved outside the “four walls”. It’s also quite cool to collab with a local or not-local college on regular class labs. They normally have fancy machines that go ‘ping’ while we don’t. Run the same lab and compare. Sometimes, the expensive machines that go ‘ping’ do no better than a meter stick and persistence. Sometimes the expensive machines that go ‘ping’ kick the meter stick’s butt.

Hope this helps. Anyone want to join some collabs this year?

Khan Academy: My Final Remarks

Anonymous — Tue, 10 May 2011 19:01:08 GMT

Many people aren’t getting the nuances of my recent Khan Academy arguments. I’ll make my final remarks and then put this thread to rest.

Khan Academy videos are nothing new. MIT OpenCourseWare has been around for TEN YEARS now. Walter Lewin’s awesome physics lectures have been available for most of those 10 years — despite the fact they are pseudoteaching, and his students emerged with no greater understanding of physics than those of professors before him.

And I didn’t have a problem with Khan Academy (as a collections of videos) until very recently.

For me, the problem is the way Khan Academy is being promoted. The way the media sees it as “revolutionizing education.” The way people with power and money view education as simply “sit-and-get.”

If your philosophy of education is sit-and-get, i.e., teaching is telling and learning is listening, then Khan Academy is way more efficient than classroom lecturing. Khan Academy does it better.

But TRUE progressive educators, TRUE education visionaries and revolutionaries don’t want to do these things better. We want to DO BETTER THINGS.

Ironically, everything that is wrong with Khan Academy has been addressed in two previous TED talks:

Dan Meyer – Math Curriculum Makeover
Sir Ken Robinson – Do Schools Kill Creativity?

According to Dan, today’s math curriculum is teaching students to expect — and excel at — paint-by-numbers classwork, robbing kids of a skill more important than solving problems: formulating them. How does Khan Academy foster problem posing and creativity?

Rather than instructing students with Khan’s videos, we should be inspiring them to figure things out on their own and learn how to create their own knowledge by working together. For example, instead of relying on lectures and textbooks, the Modeling Instruction paradigm emphasizes active student construction of conceptual and mathematical models in an interactive learning community. Students are engaged with simple scenarios to learn to model the physical world. In comparison to traditional instruction, Modeling is extremely effective — under expert modeling instruction high school students average more than two standard deviations higher on a standard instrument for assessing conceptual understanding of physics.

Watch one Modeling class in action. In the clip, the teacher says, “I don’t lecture at all. Instead, I create experiences for the students either in the lab or puzzles and problems for them to solve and it’s up to them to try to figure that out.” I’ve often wondered why this type of teaching hasn’t gotten more attention in the media. Maybe because the teacher is using simple things like whiteboards and bowling balls rather than shiny iPads and SmartBoards?

While Khan argues that his videos now eliminate “one-size-fits-all” education, his videos are exactly that. I tried finding Khan Academy videos for my students to use as references for studying, or to use as a tutorial when there’s a substitute teacher, but I haven’t found a good one. They either tackle problems that are too hard (college level) or they don’t use a lot of the multiple representations that are so fundamental to my teaching (kinematic graphs, interaction diagrams, energy pie graphs, momentum bar charts, color-coded circuit diagrams showing pressure and flow, etc.) Khan Academy videos do not align with proper Physics Education Research pedagogy.

I find it troublesome that the Khan Academy team is not spending time and energy on the pedagogy of teaching math and science, but rather on refining the gaming mechanics of Khan Academy in response to “good” and “bad” behavior of students working through the software exercises. The “gamification” of learning in Khan Academy has had disastrous consequences at the Los Altos school pilot.

There are some truly innovative learning technologies that have been
around for years. If Khan Academy wants to grow out of their infancy as electronic worksheet drills, I hope their team takes a look at these more transformative educational technologies, all of which have been researched and tested:

ANDES Physics Tutor (University of Pittsburgh and the US Naval Academy)
The history of PLATO
Multimedia Pre-Lectures (University of Illinois)

Khan Academy also promotes the “usefulness” of its dashboard for its exercise software. I find most of that information useless, like knowing how many times a student rewound the movie, how many times she paused it, or how long he spent on a module. Those times could be affected by distractions from family, self-imposed distractions like facebook and texting, etc.

Feedback I would find WAY MORE useful:

knowing how many times a student attempted the same problem
knowing the student’s answer history to each problem; i.e, what the student’s wrong answers were
knowing the type of mistake a student made when choosing a wrong answer; e.g., did he forget to square the distance, did she apply kinetic energy conservation instead of momentum conservation, did he disregard the fact that the forces where in opposite directions, did she confuse force of friction with coefficient of friction, did he assume constant velocity when in fact it was accelerating, etc.
software that anticipates and recognizes those common mistakes (like all great teachers do) and gives the students immediate, tailored feedback during the exercise

Finally, everyone is talking about using Khan Academy as a way to do more inquiry and more project-based learning. However, Bill Gates and Sal Khan and Gates are not showing any examples about what students and teachers are doing beyond Khan Academy. The news stories are not showing the open-ended problems the kids should be engaging with after mastering the basics — instead they show kids sitting in front of laptops working drills and watching videos. The focus is on the wrong things.

Khan Academy is just one tool in a teacher’s arsenal. (If it’s the only tool, that is a HUGE problem.) Khan Academy can be useful for some kids as vehicle (build skills) to help them get to better places (solving complex problems).

Now let’s please shift the focus (yours and mine) toward the destination.

Khan Academy and the Effectiveness of Science Videos

Anonymous — Thu, 17 Mar 2011 17:20:20 GMT

This must-watch video is from our friend Derek Muller, physics educator and science video blogger.

Derek writes:

It is a common view that “if only someone could break this down and explain it clearly enough, more students would understand.” Khan Academy is a great example of this approach with its clear, concise videos on science. However it is debatable whether they really work. Research has shown that these types of videos may be positively received by students. They feel like they are learning and become more confident in their answers, but tests reveal they haven’t learned anything.

The apparent reason for the discrepancy is misconceptions. Students have existing ideas about scientific phenomena before viewing a video. If the video presents scientific concepts in a clear, well illustrated way, students believe they are learning but they do not engage with the media on a deep enough level to realize that what was is presented differs from their prior knowledge.

There is hope, however. Presenting students’ common misconceptions in a video alongside the scientific concepts has been shown to increase learning by increasing the amount of mental effort students expend while watching it.

The implication of Derek’s research, both for online science videos and for in-the-classroom science lessons, are obvious. You can find more of Derek’s videos at Veritasium.com or on the Veritasium YouTube Channel. Follow him at @veritasium on Twitter.

15 Ideas for Using Digital Cameras in Science

Anonymous — Fri, 31 Dec 2010 01:41:03 GMT

1. Stop motion movies and flip books.

By taking multiple pictures, students would create a photo flip book or stop motion movie to demonstrate, as accurately as possible, a particular science concept or process. For some examples, see Dale Basler’s post Create stop-motion videos and learn physics. Another way to easily create stopmotion films is with SAM Animation software (more examples) and a webcam.

2. Photographs of Lab Setups
Take photographs of lab setups so you’ll remember next year how you set it up. Embed the photos into lab handouts and add annotations and directions.

3. Science Photo Gallery

"Where Sand Meets Sea" by Kelsey Rose Weber

Students take pictures and explain the all of the science concepts present in their photo. Display student work in the classroom and around the school. It drives home the concept that science is everywhere! Exceptional work in physics could enter the American Association of Physics Teachers’ High School Physics Photo Contest.

4. Photo/Video Analysis
This is different from #3 in that students would need to take a photo (student-created or teacher-created) and mathematically analyze it. For example, students could photograph the water coming up out of the water fountain. From the size and shape of the parabola, students could determine the initial speed of the water and the time it spends in the air. See also Speeding Problem and Kobe, Karplus, and Inquiry.

5. LED Motion Photos

by Amy Snyder, 2007

Students would take pictures with the shutter open a little longer than normal to capture motion. Attaching LEDs to the subject would allow for “light traces” in the photograph. See Sebastian Martin’s A Different Physics Class.

6. A super-accurate stopwatch
Many cameras have a video mode. It could be used to film an event that takes such a short time (less than 2 seconds) that using a regular stopwatch would yield poor results because of human reaction time. For example, students could measure the time it takes a ball to fall from the ceiling to the floor (which is less than 1 second) to determine the gravitational acceleration. Recently, we were doing a lab where students studied how the spacing between dominoes affects how quickly the line of dominoes fall. Students were getting messy data because the falling times were so short. If students had taken a video of the dominoes, they might have gotten more accurate falling times because they can look at it frame-by-frame at 30 fps.

7. End-of-year slide show for final exam review.

Make a slide show from pictures of students doing lab work and participating in demonstrations. At the end of the year, use the slide show to review for the final. Ask the students if they remembered what happened in the lab/demo and what concept it demonstrated. Plus, it’s a great way to remember all the good times during the year!

8. Video-based Labs
Sometimes, I only have one lab setup because the equipment is expensive or finicky. I used to run these as teacher-led demonstrations. Now, I can take a video of the experiment in action and students get the data from the video and do a regular lab analysis. Students must still recognize what data is important and know what to do with it, as with a traditional experiment. For a great example, see: Coin on Rotating LP. (Be sure to click “Home” to see many more!)

9. Archiving Student Whiteboard Solutions

In groups of 3, my students often write-up problem solutions on large whiteboards and present them to the class. Taking pictures of the whiteboards and archiving them on the class website would be perfect for student review and for students who were absent that day. If that gets too much to handle (sheer volume), take a picture of an exceptionally well laid out solution and put it in the “Whiteboard Hall of Fame” or the “Whiteboard of the Week.” Documenting exemplary work shows students the level of expectation we have for all of them! See more at Physics Whiteboards.

10. Mini Biography
Take pictures of students and attach to a mini biography students would submit at the beginning of the year. Display bios around the room so you not only get to know your students, but they can learn more about each other! See an example from Dean Baird.

11. Picture Dictionary

"f=force" copyright AshleyJM

As a class create a picture dictionary where students take photos that illustrate a particular science concept (force, velocity, wave, force, charge, momentum, energy, equilibrium, etc). These pictures could be posted around the room, perhaps with equations added, as the year progresses. Much better to have student made posters than teacher ones! See the brilliant and clever Flickr photoset The ABCs of Physics.

12. Photo labels for equipment drawers
With all the equipment in science rooms, photo labels would be a great way to show the contents of the drawers to help students find things and to put them away. Plus, the photos would liven up the room!

13. Video lab reports

14. Safety Do’s and Don’ts
At the beginning of the year, all science teachers go over laboratory safety and have students and parents sign a safety contract. Creating a PowerPoint with photos of do’s and don’ts would be perfect! Plus, it could be pretty humorous. If the pictures were created by the class from the year before as a final project, the next year’s students would enjoy seeing their friends in the photos.

15. Demonstrations

In the above video, which cart felt more force? (i.e., which cart’s hoop flexed the most?) When debriefing after a demonstration, there are always a bunch of students who think they did/saw something that they really didn’t. They might be biased going in to the demo, and the demo doesn’t change that bias. By taking video of the demo, show them what REALLY happened. In the above video, students tend to focus on the speed of the carts, rather than the flexing of the hoops, even when you tell them to look at the hoops!

Great, FREE Links for Engineering, Physics, and Technology!

Joan — Tue, 10 Aug 2010 22:20:00 GMT

It's that time of year again when you need great resources and you have a low or no budget---at least for this year!

If you are a teacher of physics, engineering sciences, robotics, or technology, you might want to visit these FREE resource links before the school year begins. It could save you so much time once the school year is well underway.

I have used these resources in my classroom of gifted students with great results. As a parochial school teacher, our funds are limited or sometimes non-existent, so these links can make such a difference in the quality of my lessons.
