We know that students learn easily and remember visual in the lessons. The development of ICT (information and communication technology) in the education has produced a wonderful visual presentation tool known as visualiser.
Visualiser is modern teaching aid to project a text, prepared worksheet, 2D or 3D objects onto the interactive whiteboard, projection screen, digital signage system. The lessons can be displayed larger than life with the visualiser. Educators also recognize very quickly that a visualiser is perfect tool for the educational assessment of students work. The students place their work on the visualiser base below the camera and at the end of a lesson; they can display their work to the entire class on the interactive whiteboard. This allows the entire class to give their opinion about the work. The interactive whiteboard has the ability to capture a visualiser image and do annotation over the original image.
Visualiser has a great use in the science Education. Visualiser can be used to capture images of a plant at the successive stages and the plant growth pattern can be seen. Visualiser can be used as a microscope for investigation purpose. The zoom in feature of the visualiser to view the structure of the object with the high resolution camera produces crystal clear images on the Interactive whiteboard. The parts of an electronic circuit board magnified with visualiser allow the students to see the resistors, capacitors and other components clearly and distinctly.
A caterpillar movement could be watched in real time with the visualiser. This real time movement could be captured in a movie format such as avi or wmv files through the visualiser and it could be used as teaching resource.
