Ideas in Art Class

# data[].attributes.attachment_link.readable_text
When you ask, we deliver! During my presentation at the last AOE Online Conference, many of you were wondering about using QR codes in the art room. Today I'd love to share a bit more about this cool form of technology. I'll go over what QR codes are, how they work and 5 ideas for using them in the school setting. If you'd like, you can download a simple guide for future reference located at the end of this post.

QR Code Basics

Originally used in advertising, QR codes can be found on everything from magazines to cracker boxes. An example can be seen in the image above.

QR stands for "Quick Response." The idea is that you can use your smartphone, iPod or iPad to scan the QR code, much like a barcode, and instantly have access to extra "stuff" like interesting information about a product, or special offers or coupons.

To be able to read QR codes, you need to download a QR Reader app, such as Quick Scan. To create your own QR codes to use in your classroom, you will need to use a website that generates them. There are many free options. QR Code Generator is simple and straightforward. If you'd like something a bit fancier, QRStuff.com is nice. (You can also check out tech guru Kathy Schrock's website for a huge list of QR code resources.)

Classroom Use

The ways in which you can use QR codes in the classroom are only limited by your imagination. Here are 5 ideas to get you started.

1. Provide supplemental information for your hallway displays.
When you display student work, consider adding a QR code in the corner of your bulletin board. The code could teach viewers about the style of artwork or the materials the students used.

2. Enhance your next art show with digital artist statements.
After selecting the artwork for your next art show, film or voice record each student talking about his or her work. Upload the video or audio files to your website. Then, have students generate QR codes that link to those files. Print the codes and attach them to the work. To make it more manageable, choose one grade level or find a volunteer to help.

3. Promote your art program.
There are a lot of different ways to promote your art program using QR codes. For example, instead of typing out the address to you classroom blog in the next school newsletter, include a QR code that links directly to it. Parents will be much more likely to pay you a visit! Alternately, create a code to use on a business card that you handout at back to school nights or art shows. QR Code Generator even has an option for ordering items like this (business cards, stickers, notepads, etc...). To see a list of products, click the printer icon on the site.

4. Create an artist scavenger hunt for students.
Create a series of QR codes that take students to information about various artists around the web (Alternately, create your own text to link to). Print the QR codes and hide them throughout the art room. Then, have students use their own personal devices, or use iPads to find answers to questions like: Which artist founded the cubist movement? Which artist do we know about because of the letters he and his brother Theo sent back and forth?

5. Create QR activities as part of a free choice station.
Create a set of QR codes with different drawing challenges. When finished with their work, students can scan one of the codes at random, then complete the corresponding promt. Alternately, create a set of QR codes that link to different videos about artists on the web. When finished, students can scan one of the codes, watch the video, then write one interesting fact they learned.

A Step-By-Step Guide

If you'd like, download this simple guide for future reference. Happy coding!
Have you used QR codes in the Art Room before? What did you do? Are there any obstacles to using QR codes in the art room?

Google Apps can Play a Powerful Role in Assessment
Dr. Chris McGee will be presenting a full day GAFE Workshop and numerous breakout sessions at the 2015 Teaching and Learning with the iPad Conference this November. Come join Chris and hundreds of other passionate educators at the original iPad educational conference November 12th - 14th in Raleigh, NC!
I love assessment. Seriously. It's one of the most exciting things to talk about in education. One thing we know for sure is that assessment improves learning. Check out this data from Robert Marzano's Classroom Assessment and Grading That Works (pg 10):

I mean check that out. Over a 15 week period students who were assessed more frequently, increased learning by nearly 30 percentile points. WOW! For those of us like me that love standards-based grading, this is perfect news. We can alter (or improve) our assessments using learning goals and proficiency scales to really focus our assessment to improve specific objectives. There is no doubt assessment is a powerful learning tool.

But what's wrong with assessment?

Of course, it's not all milk and honey when it comes to assessments. Let's focus on two simple things teachers do wrong with assessment:

1. They use a "gotcha" mentality. They try to craft assessments to catch students NOT knowing the answer instead of seeking to determine what students DO know.

2. They only see assessment as paper/pen or question/answer. Assessment can be so much more! Just wait and see!

Let's agree on terminology first. What is "Assessment?"

Webster's dictionary defines the verb "assess" as:

1: to determine the rate or amount of (as a tax)
2a: to impose (as a tax) according to an established rate
2b: to subject to a tax, charge, or levy
3: to make an official valuation of (property) for the purposes of taxation
4: to determine the importance, size, or value of <assess a problem>
5: to charge (a player or team) with a foul or penalty

We see often in education that teachers see assessment as definition #5 more than any other. That's the "gotcha mentality" we spoke of earlier. But what if we took the concepts in definitions 1-4 and applied them to the educational setting? This was done perfectly by Banta and Palomba in Assessment Essentials: Planning, Implementing, and Improving Assessment in Higher Education. They defined assessment as "the systematic collection, review, and use of information about educational programs undertaken for the purpose of improving learning and development."

BOOM that's it! Assessment is:

1. A series of instances as a part of a system over time

2. A collection (possibly demonstrating growth or their best work)

3. Review (read feedback through collaboration)

4. Useful in improving learning

5. Purposeful in improving learning

Now that we have a framework to think about assessment, I'll reference it when we look through the Google App ideas listed below.

Which are my favorite Google Apps on the iPad?
Google Classroom
Google Classroom allows you to set up a system that will easily allow the teacher to review student work, give feedback to students in a timely manner, leverage classroom discussions, and uncover student ideas and thoughts around specific topics.
Using Shared Folders in Google Drive
Probably my favorite of all the options. The ability to make anything on the ipad and turn it into an item that can be shared and uploaded to Google Drive is a fantastic resource. One of my favorite and all-time awesome ideas is to utilize the Camera App. I ask students to turn the camera on, and record themselves answering a question/prompt, then tap the share button to use the apps installed on the iPad to share the video just recorded.
Blogger
One of my favorite quotes from Jon Smith (@theipodteacher) from his talk entitled " The Global Refrigerator " is this: "When teachers ask students to make something for the world, they make it good. When teachers ask students to make something for the teacher, they make it good enough." So asking students to publish their ideas, thoughts, videos, images, etc. through a blog is key. A blog is an easy system to implement in the class and can provide students the opportunity to add their thoughts. The beauty of the blog is that it is always there and is a great collection of thinking. The ability to add comments also allows us to monitor learning and nudge students in the same direction: toward learning. Finally, this allows students to have an online space where their work "lives." It's so important for students in the 21st century to have a space online that creates a digital footprint.
Google Forms
Google Forms is currently a mess on the iPad. Building them on the iPad is less than ideal right now. It can be done, just not great. But we can't overlook the effectiveness of Google Forms. As the teacher in the room, it's a great opportunity to build quick, exit-slip style engaging assessments. So as classroom teachers we can build something on a computer and ask kids to interact with the Form on their iPads. Forms are easy to build into a standards classroom workflow and are an easy way to assess student learning quickly. There are a TON of add-ons we'll talk about later that can transform the simple form into a great way to provide simple feedback. That feedback is essential to improving learning.

Google Docs are an easy way to build, edit, and collaborate on a single document. A few tips and tricks I use with Google Docs:

Make the documents for each group ahead of time.

Author a document to be used as a template. Go up to the URL and change the end from "/edit" to "/copy". This will force everyone who uses it to have their own copy.

Leverage paragraph styles for easy table of contents creation.

Assign font colors at the beginning of the year. Use the "header" to code who did what on the project.

Make the documents for each group ahead of time. I know I already said that, but this allows you to own the revision history (found under file) to double check who did what.

Google Docs is an easy tool to use in any circumstance. It's probably my go-to to plan and then I move to other services. It's such a simple and easy resource to build into your classroom assessment system. Docs is easily organized in Google Drive and it also allows for comments which makes feedback simple.
Google Slides
Using Google Slides is one of the easiest way to build presentations. This is a great way to give students experiences to deliver their content to a group. But thinking creatively about Slides can open up doors to assessment. Some ideas beyond the presentation:

Break up unit goals into slides and assign students to find images, links, and resources to add to each slide building a student-driven study guide.

Have students create a non-linear slide set where they use links to move from slide to slide and demo their learning. (See my example on Solutions and Mixtures here).

Use it as a "portfolio." Set each student to have the same slide deck pre-loaded with the unit goals and outcomes (see 2nd bullet under the Google Doc section), then assign a student to populate each slide with links to their created/curated resources and images of them and their learning.

Google Slides is easy tool to use in any circumstance. It's probably my second go-to to plan, and then I move to other services. It's such a simple and easy resource to build into your classroom assessment system. Slides is easily organized in Drive and it also allows for comments which makes feedback simple.

Add-ons

Add-ons could really take up their own blog post. The idea of Add-Ons is that Google services and many of its tools are "open source" which means that people-more well versed in computer programming than you and me-can create amazing services that enrich our lives and make our workflow even simpler. Below are some of my favorite Add-ons.
Some of my favorites: Padlet
Padlet is a great tool to brainstorm ideas, curate rescues, build interactive spaces, and collaborate. We've all seen the 3M Post-It Note, now imagine a Post-It that can hold text, images, graphics, links, videos, and more. We can use a Padlet site in a ton of different ways for formative assessment. It's a great place to post a question and have students find as many different solutions to one prompt.
Google Voice
Did you know your iPad has a microphone? Did you know that your Gmail (Google Hangouts really) can make phone calls? Plug in a set of headphones and have students "dial" using the Handouts app to "call" and leave a message. Now, here's where the awesome happens. Set up your Google Voice account and use it to be able to record student information. Voice is a great way to record a selection of readings, post a quiz, or just get feedback. Next you can go to your Voice account and download those audio files and play them in class the next day as a great feedback/instructional tool. This can be done with the whole group or one-on-one.

NOTE: Rumor has it that the services of Google Voice are being phased out and wrapped into the hangouts app. The same ideas apply when/if this happens.
Peardeck
This is a cool service that is a great interactive way to get feedback on a presentation. Imagine you are going through a slide deck, and you want to do a quick, simple formative assessment. Peardeck allows you to ask questions of the class and get immediate feedback. You can ask students to type, draw, and interact through multiple choice or simple answers. The "coolness" factor goes up when you take the formative assessment data and alter your instruction mid-presentation. Now, I'm not a huge fan of the "sit-and-get" model of teaching, but sometimes it has to be done. The key to executing this "sit-and-get" model well is making it as interactive as possible and being able to shift mid-presentation to ensure learning is happening.

Here's a few more. In the time between this post and when I deliver the GAFE workshop at TLIPAD in November I'm sure there will be at least 15 more awesome Add-ons, so I hope I see you there and have more to share!
So what are some of your favorites?

Google Cultural Institute is amazing.

# data[].attributes.attachment_link.readable_text
Did you know that red is the first color that humans perceive, after black and white? It's the color that babies see first before any other, and the first that those suffering from temporary color blindness after a brain injury start to see again. Red's dominance is even reflected in how colors are defined: although different societies developed their names for colors at different times and in different ways, almost all of them named them in the same order. With only a few exceptions, the order of labelling colors was generally black first, white second, red third, and then green, yellow and blue.

Scientists have posited that societies developed names for colors according to which ones they had the strongest reaction to. This means that humans, supposedly much like bulls, have had strong feelings about the color red for thousands of years. Over time, red has come to symbolize power, love, vigor, and beauty. Do you want to know why? Take a journey with us through history to discover the surprising story of the world's most powerful color...

Red also made waves on the pre-historic art scene. Caves across the world, from Africa to Asia to Europe, bear traces made during the Paleolithic era. Drawings of animals, vessels, and people were made from painting red ochre on the cave walls, like this painting of a thylacoleo (an extinct species of lion) from the Djulirri rock art site in Northern Australia. More than 11,000 paintings have been found stretched over the site. Dated to 11,000 BCE, this naturalist animal painting may be the oldest surviving painting discovered there.

7. Raising Red Flags

World leaders have used red clothing as a way to showcase their power for hundreds of years. This portrait of Princess Elizabeth I before her accession as Queen shows a young woman preparing to assume her position as a powerful monarch. Her richly decorated red dress and red coif (close-fitting cap) send an unequivocal message of the young woman's political and moral strength. After the fall of the monarchy, the color red was then taken up by Revolutionaries around the world to symbolize new liberties and freedoms: from French Revolutionaries and their red phrygian caps, to the Bolshevik, Cultural, and Cuban Revolutions.

Courage, sacrifice, and love or anger, danger, and war? The color red can be associated with the happiest feelings as well as with the worst. Being the color that elicits the strongest reactions, it is no surprise that its symbolism can lie on both ends of the spectrum. So next time you're held up at a red stoplight (in this case the red is a symbol of danger), think about the color's revolutionary history (and maybe love too).

Ever wish you could take your class to impressive landmarks around the country or world?

Google Maps Street View makes many of those visits possible virtually - and for free.

Street View is an immersive panoramic image experience through Google Maps. It lets you feel like you're right on the street of many locations around the globe. Plus, you can virtually walk around, look up, down and around, and zoom in on items of interest.

Accessing Street View is easy:

On a computer or Chromebook, grab the yellow "peg man" in the bottom right corner of Google Maps (maps.google.com). You'll know there's a Street View available if the area turns blue when you grab the "peg man".

On a mobile device, download the Street View app:

You don't have to see the world just from the street. Many locations around the world have first-person virtual tours available. Check if they're available by finding a location in Google Maps, zooming in and grabbing the peg man to see if available locations light up in blue.

Here are 20 of them worth checking out - 10 from the United States and 10 from beyond. Click the link for each one to go to the Street View experience in Google Maps to check the location out yourself.

1. Churchill Downs - Let students take a lap around the legendary horse-racing track, see the view from the most exclusive seats and tour the rest of the campus.

2. Washington Monument - Take a walk around one of Washington D.C.'s most famous and visited monuments. And when I say take a walk, I mean take a walk - in a large circumference around the monument and down the National Mall (still inside Street View!) to see it from many angles.

3. Alcatraz Island - Take students inside the infamous prison in San Francisco Bay for an informal tour. Look inside cells and read informational posters for more details.

4. The White House - Wander around the seat of the United States government. See the Jacqueline Kennedy Garden, the Center Hall (pictured), the Vermeil Room, part of the East Colonnade and more.

5. 9/11 Memorial - See the names of those lost in the Sept. 11, 2001, tragedy in New York at the official memorial site.

6. American Airlines Center - Ever wonder what it's like to see an NBA game from a luxury suite? Walk that level of the stadium and walk into several suites for a first-hand look.

7. Metropolitan Museum of Art - Stroll around almost every part of this famous museum in New York City, checking out sculpture, paintings and more.

8. Central Park - Since you were in the area visiting the Metropolitan Museum of art, go next door and tour this popular outdoor area in New York City, walking by the Arthur Ross Pinetum and the Shakespeare Garden.

9. Yellowstone National Park - Walk the trails to see waterfalls and scenic wooded areas. Check out Old Faithful (pictured) from the view of a tourist, and then walk around the area.

10. Grand Canyon - Take a trip down the Colorado River or take in the picturesque scenes from the top.

11. Emirates Airbus A380-800 - See what life's like aboard a plane with a free lounge with food, showers for first class and personal entertainment.

12. CERN - Ever consider walking around the largest particle physics lab in the world? There are parts of CERN that have Street View that you can virtually tour. (I did, and I didn't know what anything was, but maybe you will!)

13. Alhambra - As a Spanish teacher, this is on my "bucket list" of places to visit. The Alhambra is a gorgeous palace and fortress in Granada, Spain. There's a reason for the local saying: "There's nothing worse in life than being blind in Granada."

14. Tsukiji Market - The world's largest, busiest fish market is home to a popular tuna auction. Walk the aisles to see vendors peddling their wares.

15. Blue Mosque (Sultan Ahmet Camii) - The most famous mosque in Turkey (known as the Blue Mosque for blue tiles adorning the inside) is visible from many parts of Istanbul and is a top world tourist destination.

16. Royal Opera House - Visit and walk around the home of the Royal Opera, Royal Ballet and the Orchestra of the Royal Opera House in London. See common areas as well as the performance areas.

17. Palace at Versailles - See the Hall of Mirrors, the site of many a luxurious event by King Louis XIV in Versailles, France.

18. Eiffel Tower - Go directly to the observation deck of this famous spire to see the city and the Seine River from above, or see what a typical tourist's day is in Paris.

19. The Acropolis Museum - See the spectacular views of this world landmark through the enormous windows of the museum. Plus, check out rare artifacts first hand.

20. Madrid Zoo - See the animals and the sights at the zoo in this world capital.
Want to deliver Street View experiences to your students? There are a few ways:

Find the Street View you want to show them (and point yourself in the direction you want them to see) and copy the URL (link) from your browser. Share that with students and they'll be taken to the same spot where you were.

Use Instant Street View (InstantStreetView.com) to help you find Street Views a little easier AND to display them to students.

Embed an interactive street view on a webpage. Once you've found your location, click the three dots button next to the name of the location in the top left of the screen. Choose "Embed" to copy HTML code to paste in your site.

As awesome as Google tools are for students, teachers, and schools, sometimes they can lack a feature or tool you need for your specific subject area. A common area for this concern is in mathematics. Math teachers may sometimes feel that their content and specialized symbols aren't always so easy to transfer over from the convenience of paper and pencil to the uniqueness of a digital environment.

While no solution is even going to be perfect, the good news is that there are many digital tools that can be used in the Google Apps world on Chromebooks, PCs, and Macs, that help address the needs of math students and teachers. In this blog post we are going to highlight 21 such tools. They include Chrome Web Extensions, Chrome Web Apps, and Add-ons for Docs, Sheets, and Forms. In each case they add some extra functionality that is not normally available in the standard Google tools.

Hopefully these tools will help you and your students to learn and explore math more effectively in a digital world. Moreover, many of the extensions, apps, and add-ons will actually increase your students' options for collaboration, critical thinking, inquiry, and exploration of mathematical concepts.
