Teachers need to intentionally implement technology in the classroom to help prepare students for the future (ISTE, 2019).

Illiteracy and alliteracy are an ongoing problem. Illiterate people have an inability to read. Alliterate people have the ability to read, but they lack an interest in reading (Farm, 2007). I use Ludus Reading Model that I developed in 2014. Ludus is a Latin word that means play. It comes from book Huizinga's "Homo Ludens" book in the 1950 that explained that play is important. Ludus Reading is a model that focuses-on play-based learning and I-VAKT strategies (Redcay, 2014). Research consistently demonstrates that students learn best when they use I-VAKT strategies. I represents the use of interactive technology. Students learn using different learning modalities: Visual, Auditory, Kinesthetic, and Tactile. Students experience ELA in a new way. Students are able to respond to text aesthetically.

When students are creating green screen pictures or movies then they need to be aware of intellectual property. At a young age students need to learn about what is considered plagiarism. Students need to think about what music, images, and videos are available and how can these resources be used. Media specialists often teach copyright concepts in the library (Chang, 2009); however, we need to integrate these concepts into our classroom instruction. Students learn how to use technology in meaningful ways when the purpose is embedded in classroom instruction. Students learn more by actively doing then just learning about a concept or idea.

ISTE Student Standard 6A/C-Creative Communicator: Students choose the appropriate platforms and tools for meeting the desired objectives of their creation or communication. Students communicate complex ideas clearly and effectively by creating or using a variety of digital objects such as visualizations, models or simulations.

Green Screens provide students with a creative way to visual explain and clarify their understandings and ideas (Fortay Media, 2016). Students demonstrate higher levels of understanding when they use videos and photography because it helps students activate their senses and memory (Bevan, 2017). Movies activate students students visual and auditory memory. Students become intentional when they create movies and videos because they learn to signal (direct attention to specific information), segment (breakdown length and vary pace to emphasize key points), weeding (remove unnecessary materials), and matching modality (balancing visual and auditory components) (Bevan, 2017).

Green Screens
Green Screens
Greenscreens are most commonly used by weathercasters, and various films (Burleson, 2016; Foster, 2010; & Hanke & Yamazaki, 2009). Greenscreens are used by interactive gamers too. Chromakeying (also known as green screening) involves changing the green screen to anything that you want (Hanke & Yamazaki, 2009). Chroma is the color that a camera can record, and keying occurs when an object is exported from a solid background, and a new image is added (Hanke & Yamazaki, 2009). The matte can be fixed or traveling. A fixed matte stays the same, and a traveling matte travels with the motion picture image (Foster, 2010). Chromakeying does not always include a green or blue green. Rather, any color screen can be used. In fact, Mary Poppins used a yellow background (Hanke & Yamazaki, 2009). Overtime the process has been simplified to make the technique more accessible to everyone. There are three components to the process: (1) The foreground- subject, (2) The colored screen background, and (3) The new background (Foster, 2010).

Screen Colors
Screen Colors
Red, Green, and Blue (RGB) are the colors that are easiest to key. Actually, Green Screens work best with digital cameras and devices (Foster, 2010). Green Screens are commonly used because it does not require a lot of additional luma (light). Skin tones contrast green and blue so it makes it easier to key (Burleson, 2016; Foster, 2010; & Hanke & Yamazaki, 2009). Blue Screens work better when you have someone with blond hair. The hair will appear red, and the color is difficult to adjust. Also, color spills will occur when light reflects off the back of the screen, and tints the subject (Foster, 2010). If the person is wearing green then a blue screen works better (Foster, 2010). Red Screens work well for nighttime images, and metallic surfaces, or blue and costumes. (Foster, 2010).

If you have space then you can paint the walls. Actually, if you have the space you can create the cyclorama effect (Hanke & Yamazaki, 2009). This involves creating a screen that goes on curve from wall to floor. If you do not have space in your classroom then you can paint smaller things to use like pizza boxes, mini holiday boxes, etc. Some other teachers who are limited on space have painted their retractable overhead projector. This provides you space and a Green Screen.

It is important to use the correct shade of green. The following paints are recommended EEFX, Pantone 354C, Rosco, Behr Deep Base Number 1300 Interior Flat Latex, Sparkling Apple S-G-430 and Chroma Key Paint (Burleson, 2016; Foster, 2010; & Hanke & Yamazaki, 2009). At least two coats of paint are needed (Foster, 2010). Also, Rosco's DigiComp tape is a great resource as well when painting a green screen. If you are selecting your own color then select a darker green because it will work better, and you can test out the samples to see what works best (Hanke & Yamazaki, 2009). Some people paint vinyl flooring because it does not wrinkle-free, and you can roll it up to easily store (Hanke & Yamazaki, 2009). A painted services creates the best background because you do not have the issue of wrinkles and shadows (Foster, 2010).

You can purchase green fabric and create your own stand from PVC pipes. I created my own screen. I would recommend buying thick fabric that does not wrinkle easily. Muslin or cotton fabric works best for creating a Green Screen backdrop (Foster, 2010).
