Earth
science
courses
typically
include
the
concept
of
geological
time.
The
authors
of
this
study
attempt
to
move
past
traditional
assessment
practices
and
develop
a
formative
assessment
of
students'
understanding
of
the
construction
of
the
geologic
time
scale
and
how
it
is
interpreted.
Through
this
approach
students
are
challenged
to
conceptualize
the
geologic
time
scale
by
comparing
it
to
a

This
article
presents
an
idea
for
a
classroom
activity
that
is
intended
to
replace
some
of
the
lectures
that
would
ordinarily
be
necessary
in
a
survey
of
Earth
history
over
geologic
time.
Students
take
the
lecturer's
place
in
front
of
the
class
and
present
some
of
the
material
to
their
colleagues.
They
work
in
groups
on
a
single
era
or
period.
Each
student
plays
the
role
of
an
expert
(such
as
an
oceanographer)

This
article
describes
a
study
in
which
students'
conceptual
understanding
about
the
Earth
was
examined.
In
the
study,
students
enrolled
in
introductory
science
courses
at
four
institutions,
completed
open-ended
questionnaires,
and
participated
in
interviews.
The
institutions
consisted
of
a
small
private
university,
two
large
