  1. Preparation for the Instructor

  2. Arrive 30 minutes or so early. So 7:00 pm or so.

    Turn on all the computers and log on to them.

    Do NOT launch Internet Explorer (or Firefox if that ever works again). The students will launch that for themselves.

    If necessary, set the homepage to the Course Website / Syllabus (i.e., Introductory Astronomy Laboratory (AKA astlab) which can be found by googling "jeffery astlab") and bookmark Wikipedia on all the computers.

    Introduce yourself to the students as they come in and get their names. You should arrange their names on a nonce seating plan.

    Be cheerful and friendly.

    Chat if possible.

    Begin at 7:30 pm sharp.


  3. Intro

  4. Welcome all to Intro Astronomy Laboratory Ast 105.

    I'm your section instructor David Jeffery:

    You-all should call me David. It's mandatory.

    It's hard to call your elders by their first names, but at some point you have to face up to it.

    So say it all together now, 1, 2, 3: DAVID.

    Tonight we will do an orientation that starts by going over the Course Site / Syllabus plus some intructor-specific modifications.

    We then do a brief orientation to TheSky software.

    While we are doing these orientations, we are also doing a computer orientation.

    Jump in with any questions at any itme.

    Jump in with any questions at any time in the whole semester, of course.

    1. Form groups of threes (or twos if necessary) and report to a computer station and pull up the appropriate number of chairs.

      No groups of 4 people, unless there is no other way.

      Introduce yourselves to your new friends.

      Someone will have to steer the mouse first, but you should change drivers frequently to give everyone the learning experience.

    2. First launch Internet Explorer (or Firefox if it ever works again): the icon is on the desktop somewhere.

    3. The homepage should be the Course Website / Syllabus.

      You can always find the Course Website / Syllabus by googling "jeffery astlab".

    4. Look at the favorites/bookmarks and check that Wikipedia have been bookmarked---bookmark it if not.

      Many of the questions and data required to complete the lab reports can be found at Wikipedia.

      It's usually the first reference for me.

    5. Scroll down on the Course Website / Syllabus and click on Instructor Information and Preliminary Schedule and srcoll down to my schedule. You see I'll be around most of 10:00 am--2:30 pm, except when I'm doing something specific or wandering the halls.

      Before a lab, I'll usually be around by 6:30 pm and have the lab room open by 7:00 pm.

      However, I might have to leave the lab room locked if I have to be up on the roof setting up the telescopes---by the way, our telescopes are Celestron C8's.

    6. Now we go over the In particular, see:

      1. Introductory Astronomy Laboratory Exercises
      2. Lab 1: Constellations which you never print out.
      3. Lab 1: Constellations Report Form which can print out in the lab room next week before the lab. The report form is what you write on and hand in.
      4. Task Master: Everything where you have to write something is a task.
      5. Prep Quiz: This is for self-testing to prep for the quiz that will be at 7:30 sharp.
      6. Prep Quiz Key

    7. When we've finished the Syllabus Items, we scroll up to the top and go Lab Schedule/Orientation and scroll down past the foxes.


  5. Syllabus Modifications and Additions

  6. The section instructors are allowed to make small modifications and additions to the syllabus.

    They do this because they think it the better way at least for their style of teaching.

    Also no syllabus of reasonable length can include all the details of actual lab practice.

    Some of the modifications and additions just turn up as we go along.

    However, here are the biggies for starters:

    1. Group Grading Rule:

      Everyone is required to hand in their own complete lab report form (with all group member names on it) printed out from the lab exercise web page (e.g., Lab 1: Constellations: Report).

      However, the reports of people who worked as a group are often extremely similar.

      It's thus very inefficient and tedious to mark all group members in detail.

      So each group designates one report form to be marked in detail.

      This report form is the favorite report form.

        The favorite report form has (and the other report forms do NOT have) any extra printouts or pages generated during the lab (e.g., plots, tables of data, etc.).

      The favorite report form should be labeled the favorite report form or labeled "Grade me".

      The other report forms from the group are checked for completeness. If they are complete, they receive the same mark as the favorite report form.

      If they are not complete, there will be some mark deductions.

      If there is no designated favorite report form, then yours truly will choose to one: i.e., the report from the group that looks best from a superficial examination and/or has the extra printouts or pages generated during the lab.

    2. New Group Rule:

      We usually work in groups of three. Groups of two are allowed if there is room. Groups of four are ONLY allowed if we have more than 24 people in the classroom---which usually only happens if we have a lot of makeups from other sections.


      Now if the same people always work together, then they easily fall into the particular roles and always do the same thing in their group.

      This is probably efficient at generating the reports, but it is NOT efficient for maximum learning.

      The easiest way to break the same-role syndrome is to require that you work in different groups every lab.

      So every lab, you must find new partners.

      So you should look around and give two new people a come-hither look.


      I will be keeping track of who's working with whom and break up old friends---you'll have new friends.

      By the end of the semester, we will all be friends and will find it easy to help each other.

    3. Lab Preparation:

      There are preparations for every lab given in the lab exercise itself: see lab schedule.

      Students should do those preparations before they come to the lab.

      Or at least they should arrive early to the lab and do them before the lab.

      There will be a quiz almost every week based on the preparation.

      The quiz might be omitted some weeks for some reason.

      But students will NOT know that in advance, UNLESS the instructor explicitly says so.


  7. TheSky Orientation

  8. We will now do a brief self-orientation to TheSky software.

    It's menu-driven like most software you are familar with, and so all you need to do is get used to the items. It's NOT like ENIAC.

    Yours truly will circulate in TA mode as you-all work through the steps below.

    There are two versions of the TheSky, and so two orientations:

    1. TheSkyX Orientation: TheSkyX is more-user friendly than TheSky6, but does NOT do Mercator projection and maybe other useful things. Usually, we use TheSkyX.
    2. TheSky6 Orientation: TheSky6 is less user-friendly, klutzy even, but it does do Mercator projection. Sometimes we might need to use TheSky6

    Now on to TheSky orientations:

    1. TheSkyX Orientation:

      Under construction:

      So just open TheSkyX on the desktop and push all the buttons.

    2. TheSky6 Orientation:

      Only do this orientation if the instructor so directs---or if you really want to.

      Be warned: it seems that NOT all settings for TheSky6 are quite the same.

      1. Launch the TheSky6. It is on the desktop.
      2. Go File/Ast105.sky. Ast105.sky is usually the default, but sometimes TheSky6 gets left in a weird state for unaccountable reasons.
      3. Starting from the toolbar, go Data/Locations. It should be Las Vegas, Nevada.
      4. Go Data/Time. Set date and time using the buttons: see Date & Time if necessary. The date and time always have to be set---they are NOT set automatically. Highlight hours, minutes, seconds, AM/PM to make the buttons operate for them. The clock time can also be set by dragging the hands.
      5. Starting from the toolbar, go View/Projections/Mercator. This gives a Mercator projection of the sky map.
      6. Scroll in/out using the wheel on the mouse. Scroll all the way out.
      7. Scrolling around requires using the horizontal and vertical scroll bars. They are old-fashioned, but also klutzy and sticky---they don't update the screen instantly. If they are not turned on, go View/Scroll bars. The arrow keys on the key board may also work for scrolling.
      8. Starting from the toolbar, go View/Display Explorer to open a display panel. One can also right click on the sky map to get a planel with Display Explorer.
      9. Expand Stellar, Star, and label. This displays/removes the common star names and Bayer designation. Click them ON/OFF. Leave them in off state.
      10. Expand Reference objects and Reference lines, and click ON/OFF constellation figure and constellation boundary. Leave constellation figure on and constellation boundary off. Close Display Explorer.
      11. Starting from the toolbar, go View/Labels/Common name (i.e., common name of constellation). Click ON/OFF and leave in the off state. Why the constellation names are NOT on Display Explorer (where they ought to be), I don't know.
      12. Go View/3D Solar System Mode. (The same action turns the 3D solar system mode off.) Go Display Explorer and expand Solar System. Click ON for all Solar System items.
      13. Right click on the background and go Show background. You see a sky map background, but it actually doesn't seem accurate for the Solar System.
      14. Use the mouse wheel to scroll in and out. Scroll in so that only Jupiter and the inner Solar System is seen.
      15. The horizontal scroll bar rotates the view around the ecliptic axis (an axis perpendicular to the plane of the Solar System) and the vertical scroll bar rotates the ecliptic axis itself. Hold down the CONTROL key for fine motion. Go Orientation/look/zenith to point the ecliptic axis straight out of the screen.
      16. You-all can play around some more TheSky6 after the orientation is done, but close TheSky6
      17. For reference, there is also a List of Tricks for TheSky.


  9. Preparation for Next Week Week

  10. There is a prepartion for next week when we do our first lab.

    There is a preparation for every lab as stated above.

    1. Back to the lab schedule.

    2. Click on Lab 1: Constellations.

      You NEVER print out the full lab exercise in the lab. It's long and meant to be an interactive web document.

      You can print out your own copy at home if you like.

      What you will print out Lab 1: Constellations: report form if you like tonight to have a look at it, but usually you should print out lab report forms just before the lab period since the lab exercises are continually being updated.

    3. There will be almost certainly a quiz on Lab 1 before next week's lab based on the preparation.

    4. You can now explore the course website and the TheSky if you like.

    5. When you done for the night close TheSky and Firefox.

    6. Then log off the computers.

      Do NOT turn off the computers or the screens.
