HDCP support means you can also view copy-protected sources such as commercial Blu-rays and certain Internet streaming channels.
For audio output there is a built-in one-watt speaker, or you can use the 3. If you own a Elmo pico projectors and have a user manual in electronic form, you can upload it to this website using the link on the right side of the screen. The manual also provides troubleshooting for common problems. The students then shared with other students they loved this part! Students wore different clothes and pictures were taken using the Elmo.
This clothing picture was a game we played in class. Students viewed the pictures on the big screen and took turns removing pictures while eyes were closed. Students then had to guess what clothing piece was removed.
The students loved this game and it would not have been possible without the Elmo. This is the picture of a modern-day US quarter I display to student teachers during a lecture on video applications in FLT. After viewing the fight between rival gangs in the opening scenes of M. Without a DP and when lecturing to a large group of students, the same result would be achieved — hopefully — only when all students have passed on the coin within the group, probably having a hasty look at both sides of the coins and missing the hint.
With a DP, the operation only takes a couple of seconds and all students view the relevant item collectively as they hear the question. Lesson Subject: To paint a wash background. To use paint to make a handprint. How the ELMO visualiser was used? The ELMO was used for teacher demonstration. The teacher painted the background under the ELMO for the children to see a clear modelled example. When the background was dry the ELMO was used again to show the children how to use paint correctly on their hands to make a hand print.
The children were able to a complete a good quality, handprint Christmas card. It gave them the opportunity to comment about what they saw and the teacher was able to ask them what shapes and colours they could see — can they recognise the hand shape? It showed the children the paper, the equipment they would need and how to use it in a sensible way. The teacher went through the instructions step by step under the visualiser.
It gave the children the opportunity to see clearly how to produce their own version. The ELMO encouraged them to follow the instructions closely, and allowed them to make their own high quality creations. It supported the children where necessary throughout the activity.
You can choose whether you want it plugged in to a monitor or not. If you do plug a monitor in, you will be able to see exactly what the camera can see! Make sure you have remembered to put in an SD card to record the images on to. Set your scene up on the display unit of the visualiser, or right underneath the camera.
If you are working with others, decide who is going to do what job. Start to move your characters, a very little bit at a time! Remember that it takes 8 pictures to make just 1 second of film, so you don't want to make the movements too big. When you have made your movements, make sure there are no hand in the way and press the button on your visualiser to take a photo. Repeat all this until you have finished your scene - Finished!! Creativity and imagination go hand in hand.
The students are asked to create distinctive animals, objects or creatures out of the shapes by using an erasable marker on a white board. This process helps the students develop their artistic abilities and further enhances their creativity.
This can lead to greater details in subjects such as Art, Math and Creative Writing. If you don't have an SD card slot in your computer, you could use a USB adapter or put the card into a camera.
Open Windows Movie Maker on your computer. Import all the images by clicking 'Import images' and selecting all of your photos. Delete any photos that look wrong or have hands in them! Movie Maker will want to play each photo for 5 seconds. To change this, click Tools then Options then the Advanced tab. Lower the number next to Picture Duration to 0. Select all of the photos and drag-n-drop them into the the video timeline.
Make any changes you need to the timings of any of the pictures by dragging their edges.. Teaching students drawing techniques on a black or white board had always been very difficult. The way you draw on the board, and the way you draw on a piece of paper are two different methods. We also always had problems with kids not paying attention and talking to each other, or doing their own things, when I had my back to the class. With my new document camera, I am always facing the students and know that they are paying attention.
I show them how to hold a drawing or drafting instrument and how to draw on paper. They observe the results right away. I normally ask them to start their work with me, and we advance step-by-step. Nearly floral in appearance, the DC has two bright lamps either side of the central camera, keeping documents bright and clear in dark environments.
At the higher end, this camera is well worth the spend, but be sure you plan on using all the features. Less expensive than other document cameras, the Ipevo Ziggi-HD Plus packs a lot of features into an easy-to-use, portable camera.
Hugely popular with teachers from Kindergarten to High School, the Ziggi-HD is an excellent option if you have a limited budget but still want a high-quality camera. It comes with the Ipevo Presenter software which offers several useful tools; it hooks up easily and works with minimal effort. The Elmo line of document cameras, including the Elmo model TTi Interactive Document Camera , are by far the most fully-featured classroom document cameras. With its many connectivity options, the Elmo integrates easily with other classroom technologies.
There are a few must-have features a document camera for the classroom should have to optimize its use. Then some features are nice to have and make life simpler. The quality of images and versatility may transform an ordinary document camera to an interactive engagement tool that could compete with tablets and other high-tech devices.
The imagery quality is determined by the megapixels, frames per second, digital zoom capabilities, auto focus ability, clear image quality, and additional video and audio features.
A built-in microphone assists teachers in including audio and video for a more active display. A built-in LED light may enhance the visibility of an image in poor light conditions. It may also improve seeing the details of the image if the light shines directly on the image that is captured. Advanced features that could improve the image quality are contrast, color correction, brightness, details, and saturation.
Portability may be a convenient nice-to-have feature for some but for others, it is an essential requirement. In small classrooms, a portable document camera is easily moved and stored when not in use.
The design, durable parts, and weight of the document camera influence its transportability. Portability is convenient when you need to move the document camera from one place to another or from one classroom to the next.
A portable camera makes it simpler for the teacher. A remote control gives teachers the freedom to move around during the presentation. Find out more about the Node Network.
