COURSE DESCRIPTION:
Participants will review astronomy concepts, focusing on the concepts which appear in the Virginia Standards of
Learning (SOL). Workshop participants will utilize innovative activities for teaching students physical concepts
required of students to comprehend astronomy related natural phenomena such as the appearance of the night
time sky, reasons for the seasons, phases of the Moon, motion of the stars and planets, surface features of the
Moon, and nature of eclipses.
COURSE PURPOSE AND INTENDED AUDIENCE:
This is an intensive two week long professional development workshop for teachers in the grades 6-12. There will
be two follow-up sessions in the Fall 2006 (dates to be set). This workshop will aid teachers in comprehending
and developing lesson plans to address astronomy concepts that are part of the Virginia Standards of Learning.

From Course Webpages – Then and Now
COURSE FORMAT:
The workshop will address astronomy concepts utilizing lectures, group activities, laboratory exercises and open
class discussions. Lectures will consist of various forms of presentation material including videos, computer
displays, demonstrations and transparencies. Questions are acceptable at all times. Participants should be alert
during the lecture and prepared to answer queries posed as they arise. Class activities are collaborative efforts of
three or four participants. Each participant will hand in a write-up for each class activity. Class activity sessions
will consist of both computer-based exercises and hands-on exercises. Activity reports will be turned in at the
conclusion of each class meeting.
OUTCOMES:
After attending this workshop teachers will be able to explain and develop lesson plans for use in their classrooms
to explain the appearance of the night time sky; explain the reasons for the seasons; explain the phases of the
Moon; explain the motion of the stars and planets; explain the surface features of the Moon; and explain the
nature of eclipses

iClicker Question
• The demonstration of a portable
planetarium system was excluded from the
latest teacher workshop?
• A True
• B False
From Course Webpages
• Also on course webpage

• Links to all of the vendors that provided the
handout materials
• Links to the presentations made during the two
week summer period of the class
• Links to additional web-pages that may be
useful to the participants
• Links to the tests used as pre-tests and posttests
What Worked Especially Well
• Free handouts to the teachers
• Guest speakers (from NASA GSFC, JPL, and
GMU)
• Activities (some were more difficult than others)
• Team work with Lee Ann Hennig and me
• Use of pre- and post- tests from Harvard, CAER
and UVa excerpts from SOLs
• Starlab portable planetarium demonstration
• Computer laboratory exercises
– CLEA and Starry Night especially so
• Personal response system
– Teachers stayed awake and focused without emailing too much
What Didn’t Work Too Well
• Some teachers wanted more technical
• Some teachers wanted more specific to SOL questions
• Observing sessions held at night in 2006
– Observatory not available for use in 2006
• Teachers did get to see Moon and planets outdoors in 2006
• Teachers did get to the observatory in 2007
• Some teachers felt they traveled too far
• Some teachers didn’t like the requirement of two followup sessions
– GMU Education department has data that they are necessary
– National study indicated that if no follow-up sessions, average
knowledge latency is ~ 2days
• Technical support issues
iClicker Question
• Who was not a speaker at either teacher
workshop?
• A Art Poland
• B Joe Weingartner
• C Bob Ehrlich
• D Heather Bloemhard
• E Heather Weir
Assessments
• Based upon a combination of three standard tests
– CAER Introductory Astronomy Survey (formerly the Astronomy
Diagnostic Tool version 2.0)
– Harvard General Astronomy Test
– Virginia SOL Questions related to astronomy

iClicker Question
• There was only improvement on
assessments in the earlier year.
• A False
• B True
Teacher Comments (Positive)
• Positive
– Great speakers
– Great resources
– Kept target audience in mind
– Organization of learning
– Visualizations and hands-on learning
– Good activities to demonstrate concepts
– Excellent team teaching approach
– Provided hands on materials to use in class
Teacher Comments (Negative)
• Negative
– Gear more to Virginia SOLs
• Add more content from SOL ES.14
– This was done in 2007
• Correlate better with Virginia earth science material
– 2007 had more teachers from lower grades
– Start later in day so no need to return for observing sessions in
the evening
– Have more night time observing sessions
• Others didn’t want any
– Make it more of a challenge
• Make it more intellectually challenging
• Make it less challenging
– Have a review specifically for the final
– Have better test questions
Results from Fall Follow Ups
• Teachers presented their lesson plans
• Not all teachers present
– Hard to find date that all can be present
– Those not in attendance had to videotape their presentation and
send it in to me
• Wide variance in efforts in lesson plans
• One in particular was cause for concern
– Would lead students to believe that phases of Moon caused by
shadow
– Teacher response was “I don’t care if they understand the
abstract concept, I just want them to get it right on the SOLs and
this will help them do just that”
• Follow up session #2 had teachers present results of
their use of their prepared lesson plans with pre- and
post-test results from their students
– Resistance from students and teachers to pre- post- testing
Conclusions from the Summer Teacher Workshop
• More workshops are needed and they ideally
should be over a longer period of time
– This flies in the face that teachers don’t have time
available
• Teachers can whine as much as students
– Can’t gear one workshop for all teachers
• Many are at different levels themselves
• Need both hands-on activities and lecture format
– Teachers like students have different learning styles
• If time is short don’t build materials during
activities, let teachers take home and use the
already built materials that are available in the
astronomy lab (if available)
– Murphy of UVa disagrees with this
