Then kids know how many minutes they have left to work. That gives me a minute or two to prep the next thing. Not only can everyone see the illustrations, I save the time I would spend walking the book around the group. Build Note-Taking Skills: Post the sequence for note taking as you lecture and then have students share their notes.
Are they similar? Are they hitting the most important points? Closely Analyze Readings: Project an important passage from a text the class is reading and then share your own sample annotations on that passage. Share the Writing Process: Post a writing sample and work on the opening paragraph as a group. Review the process of turning a question into a thesis and writing an interesting hook or introduction. Compare Thoughts: Have students take turns sharing their texts.
What are their annotations? What questions do they have? It should be light and easy to set up quickly. How much light do I need? Some doc cam models work best when the lights are dimmed or turned off. Some also mount a light source or two on a flexible gooseneck, independent of the camera head.
This feature makes it easier for you to adjust the lighting to display items clearly. What if I want to use my doc cam as a webcam or video camera? This will allow you to take lots of pictures of your students and their work. Do I want to connect to an interactive whiteboard? Some doc cams work seamlessly with any IWB. Others are brand-specific. Where will the funding come from? Elaborate models can cost thousands.
Do you want to appeal to your district? Consult your tech coordinator or perhaps buy your own low-cost model that you can use at home as well as at school. A doc cam is many tools in one.

Throughout this article we will discuss in-depth how a document camera works, the different types that you can choose from, what to consider when purchasing a document camera, and where to use one.
Document cameras are becoming increasingly popular for teaching courses online. You may be questioning yourself of what is a document camera, and I will answer this question below along with how it works, the different types to buy, the things to consider, where to use it, and the many benefits that it comes with. A document camera is a device that can project and magnify images of objects, paper notes, and transparencies.
It is described as being similar to an old overhead projector that almost every classroom consisted of in the past. However, a document camera is more modern, smaller, and can work remotely over Wi-Fi.
Majority of users would classify document cameras as high-resolution webcams that have arms to ensure their placement over documents, objects, or papers. Teachers, professors, and world-wide educators find document cameras to be very useful because they can write notes on paper and then present the notes to the audience of students through the document camera.
The document camera works by taking a picture of whatever object is placed underneath it and producing a live picture that multiple people can view at once. Depending on what type of document camera you purchase and how much you are able to spend, each has their own flexibility when it comes to placement of objects and forms. Some document cameras allow two or three-dimensional objects to be placed in front of the camera, and others just focus on what is placed beneath them.
Some classrooms have installed mounted document cameras from the ceilings to give the camera a bigger working area to project and magnify photos. They give a thorough explanation on how to power up a document camera and begin using it. There are three different types of document cameras, which include small lightweight models that are portable, large bulky models that are sturdy and referred to as desktop document cameras, and the visualizers that are mounted from the ceiling. The portable and desktop document cameras are perfect for the same type of environments that an overhead projector would be used in, such as an education lecture, conference, or an average sized meeting.
A portable device would be the better choice for those that travel or are on-the-go often and need to operate a document camera quickly and efficiently without any installation procedures. A ceiling document camera is commonly used over a podium or table. These devices are mounted from above to display large objects to the audience. All technology is installed in the ceiling and is typically used for videoconferencing or telecommuting. No equipment should be in the way to limit the view of the audience or speakers.
This ensures that everyone attending has a good experience and can see clearly. There are several things to consider when making an important decision like buying a document camera. Below, I will list a few things to think hard about before making this purchase.
If you know that you will constantly be taking the document camera on trips with you or even going from room to room frequently, a portable camera will work best for you. Several document cameras work better in dim lights, while others come with a light source attached to it. You could set it up to capture some pocket change on a table to teach young students about counting and grouping, for example.
Many document cameras offer maneuverability options, such as being able to revolve and swivel, which allows for it to be quickly aimed to take in a variety of classroom items. For example, you could rotate the camera head to show a small white board with modeled sentences, mixing some old school and new school techniques.
There are a number of factors to take into consideration before you start thinking about which document camera is going to best serve your needs. Here are some points to think about before you buy. Science is one of the best classes to use document cameras in a fun and interactive way. This is ideally suited for experiments where close-ups can be used to show chemical reactions or biological parts, for example. Labeling the human skeleton or zooming in on nature are other great examples of ways document cams can help teach science.
Math also benefits here with teachers able to integrate lots of teaching tools such as geoboards, playing cards, dice, unifix cubes, tessellations and more. For languages, the document camera can be a great way to read through books together. Or for the annotation of work as you go, this is helpful.
