New controlled assessment structure for GCSE Astronomy

King: GCSE Astronomy
New ‘controlled assessment’
structure for GCSE Astronomy
Julien King outlines the content
and effects of changes to the
popular GCSE Astronomy
qualification.
L
ast summer marked the first examination
session for the new GCSE Astronomy
specification from Edexcel. The new spec­
ification represents an updating of the syllabus
for this increasingly popular qualification, to
take account of recent discoveries and advances
in the world of astronomy.
However, a significant change to the qualifi­
cation in the summer, in line with other GCSE
subjects, was the change from the familiar
coursework to “controlled assessment”. This
development was primarily motivated by a need
to improve the security of work completed by
students outside the formal written examina­
tion. Following wide consultation with profes­
sional astronomers, this change has also been
used to refocus this aspect of GCSE Astronomy
firmly on observational work.
Students now have to complete two pieces
of astronomical observational work for their
GCSE, one with the naked eye and the other
using some form of optical aid such as binocu­
lars, telescope or camera. Although they may
complete the actual observations in their own
time, the written report which is finally submit­
ted must be completed under supervised con­
ditions within their school or college. There is
a wide range of observational tasks to choose
from, such as drawing lunar features, estimat­
ing stellar magnitudes, measuring light pollu­
tion levels, observing a meteor shower, using a
shadow stick to determine longitude and photo­
graphing star trails to determine the length of
the sidereal day.
Observational tasks
The new system also encourages students not to
focus both their controlled assessment tasks on
the same astronomical body. Full details of all
the controlled assessment observational tasks
can be found in the specification document
available from the GCSE Astronomy page at
http://www.edexcel.com.
The quality of candidates’ final reports on
their observations is now assessed under four
areas: design, observations, analysis and evalu­
ation. This new system helps to emphasize the
fact that all astronomical observations are
