Technology has become an important tool in teaching and in learning even in the classroom today. Projectors, smart boards and iPads have become common in different schools. The visualiser is another tool that is very useful and convenient to use in the classrooms today.
A visualiser is very similar to the overhead projector, but there is no overhead projecting. It is a kind of camera that effectively links your computer or IWB, and then projects. The camera can present whatever you want the class to see. It is easy to enhance, enlarge, and then take pictures of different objects. This makes learning more practical and accessible. This is the treasons that make it such an amazing option:
Modeling work
On a board, you can do some modeling, but sometimes it is better to have the work set out just as you prescribe it. Instead of using a board, you can simply use a pen and paper just like the students. You can allow the children to discuss their work and also present it.
Display
When you use the visualiser, you can capture the attention of the children back to class. By highlighting a part of the text that the children may have a difficult time finding, you will be able to aid the lower level readers in the class. Even in science experiments, it is easy to show the children real objects. There are schools that are able to link up laptops and computers to the main computers so as to make a display of objects.
Accuracy
The visualisers improve accuracy to a great extent. When you use a visualiser and you are teaching children to draw using tools, you can lead by example and show them exactly what they need to do. Diagrams on critical subjects like math and science require accuracy and the children are taught just how important that is.
Assessment
This is by far the greatest attribute that the visualisers can help you achieve in a class. If a child makes a wrong sentence or statement, you put it on display so that the whole class can see it and input on the next steps that should follow. There are children who are very smart and they can point out issues without any difficulty. With this kind of technology, you can receive feedback from the class immediately. The work can also be screenshot and saved in a word document. You can even place it online so that the world can give its feedback. You can save it so as to have examples of what you have been able to assess in the class.
Cons
Just like everything else, there are some cons that are associated with the visualiser. The visualisers is equipment that is fixed in a specific place and so you need to go to it and this can lead to a tiff even during class time.
Making adjustments can also take some time. For it to be effective, you need it all set and ready for use throughout because failure to this, you will lose a lot.
Visualisers for schools are a tool that many teachers are finding helpful. Purchasing one will help you take the education level to the next level and you will also assist your students to be more interactive and visual.
