She
is

Jones
wanted
to
know
if
the
use
of
the
Good
Behavior
Game
decreased
rates
of
disruptive
behaviors
in
an
elementary
school.
Dr.
Jones
collected
data
throughout
the
duration
of
the
school
year
across
two
elementary
schools.
In
school
A,
all
k-6
classrooms
used
the
Good
Behavior
Game.
In
School
B,
no
classrooms
used
the
Good
Behavior
Game.
At
the
end
of
the
school
year,
Dr.
Jones
concluded
that
the
Good
Behavior
Game
had
no
impact
on
student
disruptive
behavior,
when
in
fact
it
had.

elementary
schools.
She
wants

and
feasibility
of
peer-mediated,
school-based,
discrete
trial
training
for
teaching
multiplication
skills
to
six

Kacyn
is
a
BCBA
at
an
ABA
Center.
She
is
running
a
small
social
skills
group
with
6
children
who
have
autism
spectrum
disorder.
Kacyn
is
using
the
"Tough
Kids
Social
Skills
Curriculum."
The
goal
of
the
social
skills
sessions
is
to
build
basic
social
entry
skills
(e.g.,
making
eye
contact,
greetings,
responding
to
name).
Prior
to
the
start
of
the
group,
Kacyn
collected
data
for
each
of
the
participants.
Specifically,
she
asked
the
therapists
to
complete
the
BASC-2
(a
rating
scale
that
measures
changes
in
behavior
and
emotional
status)
and
also
collected
the
frequency
of
spontaneous
greetings
during
a
30-minute
observation
period.
She
continued
to
collect
data
for
spontaneous
greetings
during
and
after
implementation
of
the
social
skills
group.
What
is
the
dependent
variable?
-

According
to
Carr
and
Briggs
(2010)
practitioners
of
ABA
should
base
their
professional
activities
on
the
research
literature.
One
barrier
is
the
cost
of
journal
subscriptions.
A
solution
suggest
by
Carr
and
Briggs
(2010)
includes:
-
ANS
Reading
articles
in
journals,
such
as,
the
Journal
of
Speech-Language
Pathology
and
Applied
Behavior
Analysis,
which
provide
articles
for
