Visual literacy is defined as the ability to understand communications composed of visual images as well as being able to use visual imagery to communicate to others. Students become visually literate by the practice of visual encoding (expressing their thoughts and ideas in visual form) and visual decoding (translating and understanding the meaning of visual imagery).

Read online, or download this book from NASA. Also a teacher's guide for K-2 and 3-4. "The IMAGERS (Interactive Multimedia Adventures for Grade School Education Using Remote Sensing) Program is NASAÕs comprehensive Earth science education resource for the introduction of remote sensing and satellite imagery to children in grades K-8." ""The Adventures of Amelia the Pigeon" was launched in the fall of 2002. Amelia is IMAGERS second interactive web site with multimedia components to engage the K-4 audience and illustrate Earth science concepts. The Pigeon Adventure presents science concepts through metaphors and analogies that relate to inner-city life. The use of a pigeon as the vehicle for the web site provides a metaphor familiar to inner-city children, and Amelia is utilized to introduce the concept of perspective. Through aerial photography created by Pigeon cameras, the web site focuses on the benefits of a birdÕs eye view. Throughout the interactive adventure portion of the web site, aerial and satellite imagery are used to demonstrate the advances of remote sensing through the century. Amelia the Pigeon presents new insights into habitats as she explores the urban environment of New York City."

"It is well known, that the 21st century student is constantly bombarded with digital imagery. Whether it is from television, social media, advertisers, or smart phones, the relentless visual stimulation that students face has some declaring it as detrimental to student development. It is argued that with so much visual stimulation, it had become harder for students to keep their focus, hampering concentration, and hindering their ability to process information. Though this can be debated, it imperative that teachers take the necessary steps to combat these potential negative effects. This has forced teachers to recognize the importance of imagery and it's use in their classrooms."

"We're in the heart of our unit on poetry. My students have learned several strategies that poets use including repetition, onomatopoeia, alliteration, visual imagery and line breaks. This week a few students wanted to draft their poems on the iPad. We had not tried this before, so I decided to let my students "have a go."

"If you go to the Getty Images website, you'll see millions of images, all watermarked. There are more than a hundred years of photography here, from FDR on the campaign trail to last Sunday's Oscars, all stamped with the same transparent square placard reminding you that you don't own the rights. If you want Getty to take off the watermark, you'll have to pay for it. ""Our content was everywhere already."" Starting now, that's going to change. Getty Images is dropping the watermark for the bulk of its collection, in exchange for an open-embed program that will let users drop in any image they want, as long as the service gets to append a footer at the bottom of the picture with a credit and link to the licensing page. For a small-scale WordPress blog with no photo budget, this looks an awful lot like free stock imagery."

"Gorgeous, surreal 360-degree landscapes by Randy Scott Slavin are inspirational. Technically difficult and brilliantly executed, this kind of imagery has been out of reach for most novice photographers, but there is an app that can create a little of this manipulation magic."

Interesting blog post advocating for the use of analysing images in support of literacy skills.

"Any book lover can tell you: diving into a great novel is an immersive experience that can make your brain come alive with imagery and emotions and even turn on your senses. It sounds romantic, but there's real, hard evidence that supports these things happening to your brain when you read books. In reading, we can actually physically change our brain structure, become more empathetic, and even trick our brains into thinking we've experienced what we've only read in novels."

"The internationally recognized WorldImages database provides access to the California State University IMAGE Project. It has just been selected by the Library of Congress for inclusion in its historic collection of Internet materials. It contains approximately 80,000 images, is global in coverage and includes all areas of visual imagery. WorldImages is accessible anywhere and its images may be freely used for non-profit educational purposes. The images can be located using many search techniques, and for convenience they are organized into over 800 portfolios which are then organized into subject groupings"

"Geospatial" technologies--which include geographic information system (GIS), global positioning system (GPS), and remote sensing (RS) tools--are becoming increasingly important in our everyday lives. These technologies use "smart" maps that can display, query, and analyze geographic databases; receivers that provide location and navigation; and global-to-local imagery and tools that provide context and analysis.

ARKive Education is a free-to-use, multi-media resource bank for teachers and other educators.

"We all know and love Google Maps. But did you know that the Street View Pegman has few more tricks up his sleeve? Google Street Views takes some of the most amazing Street View imagery, as well as user submitted photography, and turns it into a unique platform where students can explore every corner of the Earth in full panoramic glory. From the top of the world's tallest buildings to the depths of the ocean floors, it really is an immersive and awe-inspiring experience."

"Here at WIRED Science, we're big fans of science graphics. And not just the fancy, big-budget ones, but charts and figures and visualizations: the folk art of scientific imagery. In this gallery are our favorite graphics of the year. They're in no particular order (though we did save a treat for last). Each tells a story with elegant simplicity, and sometimes even beauty. Enjoy!"

"Here are some great iPad apps to put the world at your kids fingertips. Using these apps, kids will get to explore the geographical and cultural richness of the world and learn interesting facts and information about different continents and cities. Information includes things such as population, languages spoken, flags, cultural mores, and many more. Some of these apps also provide reference maps and 3D imagery."

""The best camera, is the one you have with you." Chase Jarvis It's a classic photographic mantra, a call to action for image-makers everywhere. And these days, the camera you are most likely to have with you is the one embedded in your smart phone. But do you know how to use it? What about your students? There are many great features built into our mobile devices for photography, and a myriad of apps to produce exciting visual imagery. While some teachers and students are experienced users creating highly original work using complex workflows and inventive techniques, in my workshops I am constantly amazed that it's some of the most basic tips and tricks that get the most cheers, the practical solutions that are big wins for our classroom context. So, here are six foundational tools built into the iPhone and iPad camera that all teachers and students should know."

"Ten years ago, seeing a drone zoom over a college campus would have been unusual, to say the least. Today, however, several institutions are using the technology to support learning, research and even administrative work, such as capturing footage for a marketing video. Unmanned aerial vehicles have been in use since the 1990s, primarily to support military, border security and other public operations, according to the Federal Aviation Administration. Consumer adoption began to accelerate a few years ago as hobby drones became more advanced and less expensive. From 2014 to 2017, consumer drone shipments jumped worldwide by 7 million units, according to a Business Insider Intelligence analysis. That's about when higher education institutions began to realize UAVs could play a role on campus, according to Venkata Krishnan Seshadri, industry lead at market research provider Technavio. "Drones facilitate application-based, practical learning, which helps students understand and remember key theoretical concepts," Seshadri says. "Using drones significantly reduces risks and costs. For instance, in archeological-related courses, drones are used to capture aerial imagery, which increases the quality of learning without safety issues.""
