Make your classroom interactive by using a visualizer

Tuesday, August 27th, 2013 | Gadgets, technology | Comments Off

Teachers, do you want to make your classrooms more interactive?   A visualizer may be just the piece of equipment that you require.

A visualizer – also called a visual presenter, digital visualizer or a document camera – is a digital camera which, connected to your computer, allows you to display images through a data projector.  It functions in the same way as the old overhead projector, but with all the additional benefits that modern technology offers.

You can use a visualizer to display a page of a textbook, allowing you to zoom in, highlight text and make annotations.  Whatever is done, can be saved; it is no longer necessary for learners to spend valuable time to take down notes.  A good visualizer will allow you to record the work you are displaying, as well as your voice, so that the entire lesson can be made available for revision, or for those learners who could not attend class.

At times you may want learners to see a real item – not a picture.  This can be a challenge if the item is very small, particularly if you’re teaching natural science or biology and you want learners to observe details that can’t be detected with the naked eye.  Some visualizers have a microscopic function … just imagine how useful that would be in a class.  Learners can remain at their seats while you zoom in on detail; it is no longer necessary for them to queue up to get a turn looking through a microscope.

Have you ever done a science experiment while forty learners are crowding around you to see what’s happening?  Doing the experiment on the display surface of a visualizer allows learners to view the experiment in real time from their individual desks.  Snapshots at certain stages of the experiment can be taken and then incorporated in later discussions, future lessons or revision sessions.

Whereas a scanner limits you to displaying two dimensional images, a visualizer allows you to display two or three dimensional items.  When you rotate or move objects, learners can see the details of the object from different angles.

With a document camera in the class, any object can be viewed as the opportunity presents itself – in this way spontaneity is added to your classroom … and isn’t this what interactivity is all about.

How much value does a document camera have in the classroom?

Thursday, December 23rd, 2010 | technology | Comments Off

At times you may want learners to see a real item – not a picture.  This can be a challenge if the item is very small, particularly if you’re teaching natural science or biology and you want learners to observe details that can’t be detected with the naked eye.

A document camera is just what you need when you’re looking for a tool to zoom in on small objects so they can be displayed to the class.  This device is also called a visualizer, visual presenter, or digital visualizer.  A document camera is a digital camera which, connected to your computer, allows you to display images through the data projector.

Bear the following facts about the functionality of a document camera in mind when you’re weighing up the benefits of this electronic tool with the price you’ll have to pay for it:

Whereas a scanner limits you to displaying two dimensional images, a document camera allows you to display two or three dimensional items.  When you rotate or move objects, learners can see the details of the object from different angles.

The microscope function of a document camera allows you to display microscopic objects.

When you’re using a textbook in your lesson, the page you are working with can be displayed to the class.  If the image is displayed on an interactive whiteboard, you’ll be able to make annotations on the board for the benefit of the learners. 

A document camera allows your learners to explore and experience new worlds – it has great potential in transforming your classroom into an interactive one.

How much value does a document camera add to my interactive whiteboard?

Sunday, January 24th, 2010 | IWBs | 2 Comments

The large size of an interactive whiteboard makes it an ideal medium on which small objects can be diplayed in an enlarged format – in this way learners can study them in greater detail.  This is particularly useful in natural science and biology where you want learners to observe details, which can not be detected by the naked eye.

You need a tool to zoom in on small objects to make them dislayable, and the document camera is just the one you need.  This device is also called a visualizer, visual presenter, or digital visualizer.

A document camera is a digital camera which, connected to your computer, allows you to display images through the data projector onto the interactive whiteboard.  Your interactive whiteboard vendor may be able to supply you with a document camera made to work with your specific board, but generic models are available too.  Before you buy, first check its functionality.

With most document cameras you’ll be able to do the following:

When you are are using a textbook in your lesson, the page you are working with can be displayed to the class.  With the image of the page displayed on the interactive whiteboard, you can highlight portions or make annotations on the board.

Two or three dimensional items can be displayed to the class.  When you rotate or move objects, learners can see the details of the object from where they are sitting.

A microscope function allows you to display microscopic objects.

Have you ever done a science experiment while forty learners are crowding around you to see what’s happening?  Doing your experiment on the display surface of the document camera allows learners to view the experiment in real time from their individual desks.  Snapshots at certain stages of the experiment can be taken and then incorporated in later discussions or future lessons.

The image of whatever is displayed can be saved for later use.

Spontaneity is added to your classroom, since you can view any object as the opportunity presents itself.

A document camera adds substantial functionality to your interactive whiteboard.  It allows your learners to explore and experience new worlds.

Once you’ve mastered your interactive whiteboard, the document camera is a useful addition to your interactive classroom.
