We have visualised IT in St. Joseph’s
The
days of hearing “Teacher, I can’t see it from here” are finished in St.
Joseph’s. We introduced visualisers
into all classrooms in Spring 2007. A visualiser, also known as a document
camera, is one of the most versatile and useful tools in our classroom. Video
visualisers and document cameras are electronic imaging tools for displaying 3-D
objects via a projector onto a screen / whiteboard.
Having
30 pupils crowded around a table is never ideal. Using the visualiser everyone
gets a great view - without ever having to leave their seat. The teacher
can demonstrate to the whole class
at once, something previously only possible on a group or one-to-one basis.
Documents such as books, copies, papers, magazines or maps can be placed
underneath the visualiser lens so that they can be projected onto a screen. 3D
items such as coins, leaves, insects or other artefacts can be displayed to the
whole class. Most visualisers have a zoom facility allowing the teacher to
display the smallest of details. Any non-digital material can be instantly
shared by all.
The
digital video camera is fixed to an arm on a base. The computer and visualiser
may be connected to the data projector simultaneously. The teacher chooses which
is to be displayed by the press of a button.
Unlike
the overhead projector, specially prepared transparencies are not required.
Visualisers can show documents, books, art work and 3D objects directly. Entire
pages can be shown or minute details zoomed into.
A still image can be
captured of the object and saved in the visualiser. The image quality depends on
the camera resolution but is generally very good. Detail zooming gives you great
flexibility, and really help push the boundaries of how to use
technology in a whole class teaching environment. It opens up many more ways of
promoting effective teaching within whole class / group contexts
Visualisers
are a simple yet very powerful technology to use in the classroom. They can be
used across the entire curriculum, in a number of different ways. It is a simple
to use technology that appeals to both teachers and pupils.
The
following are just some examples of how visualisers are used in our classrooms:
The
Visualiser is an effective and efficient tool for collecting and collating
pupils’ writing and art work for recording and assessment purposes. It is engaging,
interactive and simple to use. Time
and money is saved in photocopying, access is instant and presentation is in
colour. It gives
the opportunity to take many of our existing teaching practices and engage the
children in a more exciting way.
Teachers and pupils find
that this technology enables them to do things in new and transforming ways. The
key advantage is that the whole class can see what is being demonstrated at the
same time. They have proven to be one of the most teacher and child friendly
resources in the school.
