                                 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 Webpage
                                     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

  week summer period of the class

  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
    What Didn’t Work Too Well
• Some teachers wanted more technical
• Some teachers wanted more specific to SOL
  questions
• Observing sessions held at night
  – Observatory not available
     • Teachers did get to see Moon and planets
• Some teachers felt they traveled too far
• Some teachers didn’t like the requirement of two
  follow-up sessions
  – GMU Education department has data that they are
    necessary
               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
• Pre-test average of scores was 72%
• Post-test average of scores was 82%
• EVERY INDIVIDUAL SCORE INCREASED from
  pre-testing compared to post-testing

• Room on course evaluations for comments
  – (see next slides)
 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
     • Correlate better with Virginia earth science material
  – Start later in day so no need to return for observing
    sessions in the evening
  – Have more night time observing sessions
  – Make it more of a challenge
     • Make it more intellectually challenging
  – Have a review specifically for the final
  – Have better test questions
 Results from Fall Follow Up #1
• 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 will have teachers present results
  of their use of their prepared lesson plans with pre- and
  post-test results from their students
Views of Professional Development
• Contradictions in Professional Development
  – Professional development courses are “key
    mechanisms for providing teachers with ongoing
    training opportunities”
  – Most professional development courses have a short
    term effect and lack adequate follow-up
• Conclusions from two studies sponsored by the
  U.S. Department of Education
  – “Formal professional development typically lasts for
    the equivalent of 1 day”
  – This point was highlighted by Donna Sterling
  – Not a particularly new issue, as it was highlighted by
    Thomas Guskey over 20 years ago
Views of Professional Development
• More conclusions from NCES
  – “teachers were most likely to have participated in
    professional development that focused on state or
    district curriculum and performance standards”
  – “the extent to which teachers felt that participation in
    the activity improved their teaching depended on
    whether that activity was followed by various school-
    based activities,”
• The VESC workshops were focused on the
  Virginia Standards of Learning.
• There must be two distinct follow-up sessions in
  the ensuing fall semester for the summer
  workshop in spite of the lack of time teachers
  have to participate
             Some Parting Thoughts
• 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 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)
• Don’t count on promises of contractors
   – Construction of observatory and conference room is going to be
     one year late
   – Total construction is $1.7 Million overbudget (~10% of building
     cost)
