In addition to the process of setting up and transferring
databases between remote sites we need to cover the
following theory. A range of worksheets (Sheet 1) (Sheet 2) (Sheet 3) support the activities
and explain the concepts involved in this project. Two
Powerpoint / Office displays have been produced to assist
teachers in the delivery of this project.
N.B. Some of these concepts will be difficult for lower
set pupils. It is envisaged that top set pupils will have a
high level understanding of all the concepts below. Lower
set pupils will, as a minimum, complete the database task
and send the database as a CSV file across the
Internet.
Yr. 9 pupils have an ICT lesson every 2 weeks. It is
envisaged that more enthusiastic pupils will complete extra
work during lunchtimes.
