Introductory Astronomy Laboratory (AKA astlab) Ast 105: 3 hours, 1 credit hour: University of Nevada, Las Vegas (UNLV)

Course Website / Extended Syllabus

Syllabus: Short Version

: Spring / Summer / Fall, BPB 248/249/250, MTWR, 7:30--10:20 pm ** / ***


** Astro labs always START in the first week of classes. Of course, lab section periods that coincide with UNLV holidays do NOT meet. So lab sections with section periods coinciding with UNLV holidays in the first week do NOT meet in the first week.
*** For summer semester courses, the lab nights are TWR---that is all of TWR for each individual section---it's a compressed course. The lab time period is 7:00--10:00 pm, but we can move the lab period to later to have more dark time if everyone agrees.

  2. Transparent Course Summary

  3. With Remote Instruction Qualification 1 items inserted where needed.

    1. Course Tasks:
      1. Prep for the laboratory exercises doing the prep as specified by your lab section instructor. However, it will always include reading over the lab exercise to be done from Introductory Astronomy Laboratory Exercises. For remote instruction, prepartion for and doing the lab exercise are the same thing.
      2. Follow the step-by-step the laboratory exercises which involve answering questions, making diagrams, etc. The labs generally need some extra instructions from the lab section instructors. This is group work. For remote instruction, the student is on their own---unless students can get a friend to help out which is recommended because the work should be group work and it's more fun.
      3. Answer lab questions that require a sentence answer with a sentence---at a bare minimum a sentence starts with a capital letter and ends with a period. Almost always whether a question requires a sentence answer or not is implicit---you should just know.
      4. Almost all parts of a lab exercise where the student has to write something down are specified explicitly as tasks: Task 1, Task 2, Task 3, etc.
      5. Prep for the laboratory quizzes doing the prep as specified by your lab section instructor. For remote instruction, doing the lab exercise is the preparation.
      6. Do the laboratory quizzes. This is individual work.
      7. Do the In-Person Lab Final or the Remote Instruction Lab Final. This is individual work.
      8. Work as hard as you can in this and every course subject to all the constraints in life.


    2. Criteria for Success:
      1. Really and truly, the most important criterion for success is having achieved those Student Learning Outcomes listed above. Grades are important, but it's what you learn in a class which is most important for the classes to come and the rest of your life.
      2. That said, to get acceptable/good/great grades do all the labs, all the quizzes, and the Lab Final at the acceptable/good/great level. There is absolutely NO extra credit and NO retakes---there are makeups.
      3. If you need a specific grade for some particular thing (e.g., your major, a grant, a scholarship, etc.), don't undershoot. Don't imagine you can fine tune your effort just to get that specific grade. Overshoot.

  8. Syllabus Items

  9. The main items of the syllabus are below.

    As in any course, there are lots of fine details---such as those specific to the individual lab section instructors---that are just learnt along the way.

    Items:

    1. The Course Website / Extended Syllabus---which you are viewing right now---is at URL

      It can be found by googling "david jeffery astlab unlv", but it may NOT turn up as the first item.

    2. The Course Website / Extended Syllabus can be updated anytime.

      Yours truly does NOT like to do that after a semester has started, but sometimes small updates or even large ones are needed.

      Any large updates will be called to the attention of the students by email and during the lab periods.

    3. See Minimum Syllabi Content above for details that are common to all UNLV syllabi.

    4. Rebelmail: UNLV course policy supposedly requires that all UNLV email to student (including from instructors) go to their Rebelmail accounts.

      However, since MyUNLV actually sends emails to any email account students specify, we can assume that the Rebelmail account requirement is at present a dead letter.

    5. The individual lab section instructors have some freedom to adjust the course to suit their own preferences.

      They will make those adjustments known to you in the lab period itself and sometimes by email communications.

    6. Co/prerequisite: Ast 103, Ast 104, or the consent of the lab coordinator.

      Consent is relatively easy to get, but the lab coordinator does want to make sure that you can succeed in the course without the co/prerequisite.

    7. Lab Manual: We use online labs: Introductory Astronomy Laboratory Exercises (IALE). Access to students and lab section instructors only.

      There is NO manual to buy.

      The labs are still a bit under construction, and so the lab section instructors may need to compensate for deficiencies and gaps for awhile.

      We previously used Diane Pyper Smith's A Guide to Astronomy, but this is now phased out.

    8. NO food is allowed in the lab room. Drinks are allowed, but NOT at the computer tables---it is all too easy to spill them with all the people clustered around the computers.


      Clean up any mess you make with a drink.

      NO food or drinks on the roof where we do our outside observing.

    9. NO smoking inside, of course. NO smoking on the roof.

    10. Evaluation:

      1. Evaluation for In-Person Instruction (IPI):

        There are 3 evaluation items specified in the table below:

                                                           to pass the course.  A pass is 60%.
                                                           Rationale:  This is a lab course 
                                                           and lab skills are what are to be

                                                           in the range 6--10, but only

                                                           Rationale:  The quizzes enforce
                                                           prep/recap and allow individual
                                                           students to be better evaluated.

                                                           in order to pass the course.
                                                           Rationale:  The lab final ensures
                                                           that certain simple skills are 
                                                           learnt by all students.

      2. Evaluation for Remote Instruction (RMI): Remote Instruction Qualification 2:

        There are 3 evaluation items specified in the table below:

                                                           all tasks required for RMI and

      3. Grading Policy:

        The final grade is assigned on the 12-point scale (A,A-,B+,B,B-,C+,C,C-,D+,D,D-,F) or the 5-point scale (A,B,C,D,F) at the discretion of the lab section instructor.

        Typically, a section GPA will be in the B- to B range, NOT counting the grades of students who withdraw from the class officially or unofficially. Official university section GPAs will often be lower than the section GPA arrived at by lab section instructor since the official university section GPAs include students who are officially still in the class, but have de facto abandoned it---such students usually get F's.

        In any section, there do NOT have to be any D's or F's---there do have to be B's and C's. There will usually be A's---but not necessarily.

        The lab section instructors keep track of marks and assign the letter grades, NOT the lab coordinator.

        For in-person instruction (IPI), students should check with their lab section instructors to find out their current standing in the course.

        Remote Instruction Qualification 3: For remote instruction (RMI), students can always access their current grade record at Ast105: Section 1001 grades with anonymous aliases: remote instruction. WebCampus is NOT used.

        Each grade record consists of 4 lines: example of a semester end complete grade record with line descriptions below:

        Psamanthe  Cumulative Ave.= 93.80  Dev.=  2.500  Letter Grade=A 
        Ave=100.0     1    1    1    1    1    1    1    1    1    1
        Ave= 87.0     9    8    3    7   10   10   10   10   10   10
        Ave= 95.0    95 
                
        Line Description:
        1. Anonymous alias, current cummulative average, deviation from mean 0, current letter grade. All students have anonymous alias already, but they do NOT know what that is until yours truly informs them in the first week of class. Yours truly just uses the names of astronomical objects. If you wish to choose your own alias, you may, but it CANNOT be recognizable as anyone's name: e.g., Kraken@Cthulhu, Iset17, @Doberman.Pinscher. 2) Lab report average, lab report raw scores all 1 out of 1. 3) Quiz average, quiz raw scores out of 10. Note that in a real class NOT all quizzes are out of 10: they can be out of less or more. 4) Final average, final raw score out of 100.

        As described above the class GPA will probably be in the B- to B range.

        However, until all marks are in, I will be using simplified 5-point fixed scale:
        1. Above 50 %, C-. This just means satisfactory or better.
        2. 47--50 %, D+.
        3. 43--47 %, D.
        4. 40--43 %, D-.
        5. Below 40 %, F.
        The reason for this is that in small class or a in-person instruction course, it is very difficult to find a set full fixed scale or a curve that adequately rewards students. After the marks are all in, yours truly will have a better idea how to distributed the grades fairly.

      4. Evaluation Items Explicated for In-Person Instruction:

        1. Lab Reports:

          Lab reports are the marked results of doing the lab exercises.

          Students typically work in groups of 3. Two-person groups are allowed. FOUR-PERSON GROUPS are FORBIDDEN, unless there are more than 24 people in the lab room which might happen on a rare occasion when many students are doing makeups from another section.

          Generally, each student must write a lab report, unless otheriwse directed by their lab section instructor.

          As indicated above in subsection Evaluation, lab reports are worth 50 % of the final grade.

          Lab reports are mainly filled in during the lab period and are usually handed in at the end for grading.

          General questions (i.e., questions not arising in during the lab period itself) can be done ahead of time. This is recommended as part of the preparation.

          If a lab exercise cannot be completed during the lab period---usually because some observation can't be carried out due to weather---the lab can be completed in the next period.

          The lab section instructors set their own preparation and quizzes.

          Do the PREPARATION required by your lab section instructor.

          The specified preparation is for the labs and the quizzes.

          The lab section instructors decide on their own marking schemes for the labs.

          Note, however, that group members often have very similar reports, and so marking them all in detail is time-consuming and redundant. To deal with this situation, here are three suggestions for the lab section instructors:

          1. Mark one member of group's report in detail---the favorite report form---and just give all members that mark provided the reports of the other members are complete. Marks are deducted for incompleteness. The favorite report form should be chosen by the students. If the students don't make a choice, the lab section instructor will.

          2. Give 80 % of the marks for completeness and 20 % for a detailed marking of an important part of the lab chosen arbitrarily and NOT known to the students in advance.

          3. Ask only for a group report.

          The marks on lab reports are generally fairly high.

          But remember you must pass 6 labs at least to pass the course. See the subsection Evaluation.

        2. Required Items For Labs:

          1. A printout of the lab report form for the lab of the night.
          2. Ordinary pens, pencils, erasers.
          3. Students should have a light source for working on the roof since it will be quite dark. A flashlight or a penlight will do. A cell phone light is not ideal, but suffices. Absolutely, NO laser pointers: they do not serve the function and are dangerous.

        3. Quizzes:

          As indicated above in the subsection Evaluation, quizzes count for 40 % of the final grade.

          The quizzes are usually given at the start of the lab period.

          They will consist of about 10 questions and take about 10 minutes.

          People who come late have to do the quiz out of the classroom---if the lab section instructor permits late starts at all.

          The specified preparation is for the labs and the quizzes.

          The lab section instructors may make up their own quizzes. However, the lab coordinator does provide a standard set for the lab section instructors who wish to use it---but this set is NOT yet quite complete for the new labs---quizzes 6 and 12 have yet to be completed.

          For the rules on makeups for the quizzes, see subsection Makeups below.

          There will be 6 to 10 quizzes and only the top 5 count.

          So you can afford to miss or not prepare for at least one quiz.

          But the since the quizzes count for 40 % of the total grade, you should prepare for at least 5 of them seriously.

          It is recommended that you do all the quizzes and prepare for them all seriously.

          The lab report marks often do NOT vary much between students. The quiz marks often vary a lot. So the quiz marks often have a strong influence on the letter grades students get.

        4. Lab Final:

          As indicated above in subsection Evaluation, lab final is worth 10 % of the final grade.

          But you must pass it to pass the course.

          The rationale for the lab final is that it ensures that certain very simple skills (observational and otherwise) have been learnt by all students.

          If you do the preparation for the lab final, then you should pass it easily.

          The lab final is usually given during the last period or last two periods of the semester with different groups of students doing the lab final at different times. Students only come for their allotted times.

          Early lab finals (if the lab section instructor permits them) and lab final makeups are arranged with the lab section instructors.

          The lab section instructors set their own lab final and set the preparation for it.

          The lab coordinator acting as a lab section instructor has his own lab final which the other lab section instructors can use if they like.

          If you are in the lab coordinator's sections, see DavidJ's Lab Final Instructions. These instructions are updated for each new semester as the lab final time approaches.

        5. Makeups:

          Makeup Notes:

          1. For regular/summer semesters, there will ALWAYS be a makeup-practice week/period before the lab final week, unless the class unanimously decides in an unpressured way to postpone the makeup week/period until after the lab final week.

            So students can always makeup at least one lab and one quiz before the lab final.

            Students do need to take the initiative if they need makeups.

          2. For regular semesters, there will be a SECOND makeup week after the lab final week if NEEDED.

            For summer semesters, special arrangements are needed if a second makeup period is needed.

          3. More than 2 makeups are possible if a student can come multiple nights or pack more than one set of makeups into one night. For mutliple nights, students may have to make arrangements with lab section instructors other than their own. Students need to take the initiative on this.

          4. The lab section instructors are NOT required to offer more than 2 makeups if a student has volitionally missed more than two labs.

          5. Note that if students have missed many labs, it may NOT be possible do them all in an educationally useful way as makeups.

            If it's NOT, the makeups won't be offered. Each student's case will have be judged on its own merits.

          6. Actually, it is overwhelmingly BEST if students can arranged makeups in the time frame (same week, adjacent week) when they missed a lab. Usually, the same lab is being done in another section in the same time frame. They should contact their lab section instructor about such makeups as soon as possible.

          7. Missed quizzes are usually easy to makeup, but the lab section instructor sets the rules about that.

            The policies require that students be given the opportunity, if reasonably possible, to make up marked items missed for excusable absences: these being religous holidays and official extracurricular activities.

            Thus, in general, you do NOT have to take a drop or a zero for such missed marked items. You can request a makeup and your lab section instructor will try to accommodate you.

            In the lab course, we do NOT have a dropped lab, but quizzes beyond 5 are drops.

        6. Lab Safety:


        7. Student Conduct:

          It is the responsibility of students to be well behaved and to carry out the lab activity in a serious manner.

          It is the responsibility of the instructor to stop all disruptive or other inappropriate behavior in class.

          Instructors can require that misbehaving students leave the classroom for the remainder of the period. If the students refuse, the instructor will call the UNLV Police at 911 and have the UNLV Police deal with the situation.

          Any serious misbehavior may result in the instructor filing a student of concern report with the Office of Student Conduct (OSC). Anytime the instructor has to the call the UNLV Police, there will be a student of concern report.

          Under certain circumstances, the instructor is required to contact the UNLV Police: e.g., in the case of a distressed student showing signs of alcohol or drug abuse.

          Lab section instructors and students are encouraged to review the UNLV Student of Concern Guide Book. If the link is dead, UNLV IT has moved the guide book again and try googling UNLV Student of Concern Guide Book.

          The most relevant pages are 9--10.

      5. Evaluation Items Explicated for Remote Instruction: Remote Instruction Qualification 4:

        1. Lab Reports:

          Students should do the labs per Lab Schedule. It is best to do the lab on its recommended date. However, there is NO absolute deadline for any lab---except the ABSOLUTE deadline for all items is the Monday after the course ends since grades are due Tuesday.

          You work through each lab thusly:

          1. Do NOT print out the lab itself. It is very lengthy and consumes lots sheets of paper. Just read it from the screen. You can if you wish and have a printer, print out the report form and fill that out as you work through the tasks. However, even the report form is rather long. So you may prefer to do any writing for the tasks just on a piece of paper. Note that you are NOT handing in lab answers at all. You will just report having done the lab as explained below.

          2. Read along and whenever you come to a numbered task (e.g., Task 1, Task 2, etc.), do the task as best you can to do it: give an answer of some kind---a right one is best. Hopefully, the narrative and the suggested links of the lab will give enough information. Some tasks are easy. Some will take some effort. Inevitably, the student must think sometimes.

            The student can email the lab instructor for help, but that is often inefficient since the response might be relatively slow and email responses often have their own ambiguities relative to students.

            Yours truly has noticed that students often try to skip the lab narrative and just do the tasks, but then they don't know how and start doing Web searches for information which is usually hopeless---the Web doesn't have the specific information anywhere the student can find and for definitions, the online definitions for astronomy terms that first appear are often misleading. Inevitably, the student must think sometimes and the lab narrative is designed to give the student the information to think on.

          3. The student can have a friend work through the labs with them. This recommended. The labs are intended to be activity-based group learning. The student, of course, should make sure that they understand things---it's NOT so important if the friend does NOT---they're just doing the labs for fun---they do NOT get marks or a grade.

          4. The tasks are all listed in the Task Master for each lab: e.g. Lab 1: Constellations: Task Master.

            You do must attempt all tasks, except those labeled IPI only (i.e, in-person instruction). The IPI only. Tasks usually involve using things NOT available to RMI students: telescopes, lab equipment, licenced software.

          5. After you have completed each task with some kind of answer, you check your answer against with the lab key. For example, Lab 1: Constellations has Lab 1 key. The student must try to understand the answer.

            To access the lab keys, the student will need the SUPER-SECRET username password which the lab instructor will email to the students.

          6. For RMI labs, the last task will usually be Task: Naked-Eye Observation which is done after sunset.

            Note that in the summer semesters during June and July, the stars will start coming out clearly only ∼ 8:30 pm at the latitude of Las Vegas, Nevada: ∼ 36° N.

            For observing, you can always check Sky map: Las Vegas, current time and Weather: Las Vegas.

            If you are NOT in or near Las Vegas, Nevada, you will need to update the sky map's constrol fields. The Task: Naked-Eye Observation gives you directions for doing updates.

          7. The labs do vary in length. Note that Lab 2: The Sky and Lab 5: Planets are particularly long and may take 4 hours of concentrated time. On the other hand, Lab 11: Galaxies and Lab 12: Cosmos are rather short and probably take less than 2 hours of concentrated time. Most other labs are somewhere in between.

            It is understood that RMI students may NOT be able to do a lab single session.

            However, it is best that students do and report the 2 or 3 labs on the Lab Schedule for a given week in that week. It is very tedious to catch up, if you fall much behind Lab Schedule.

          8. A lab has been completed (i.e., the all required tasks of that lab have been completed).

            The student can then:

            1. report that that they have completed the lab. The report should be in an email and should have the form: "Last name, First name, lab X done": e.g., Jeffery,David,Ast105, Lab 1 done.

              That is all. The student gets a mark just for having reported having done the lab.

            2. just go onto complete the quiz for that lab and then report quiz answers. It is ASSUMED that if you report the quiz answers for a lab that you have done the lab too and you do NOT need to make a separate report of having done it.

              This is the recommended procedure since it saves emails and possible confusion.

          9. Required Items For Labs:

            For RMI labs, the student needs access to the Web, pen or pencil and writing material.

            If a student has a printer that would be convenient, but NOT necessary. Without a printer, a student will sometimes have to sketch sky map by hand---but that has its own educational value.

            The RMI labs, do NOT use things NOT available to RMI students: telescopes, lab equipment, licenced software.

          10. Quizzes:

            Every lab has an associated quiz: e.g., Lab 1: Constellations has Quiz 1.

            The lab is the preparation/study guide for the quiz.

            Soon after the student completes a lab, they should do the quiz.

            The quiz is individual work and it is closed book/note/Web: only the student brain can be used for information. A calculator/phone can be used for calculations and only for calculations.

            The quizzes are time-limited. The student has 2 minutes per question. So for X questions, the student has 2X minutes. Students with DRC accommodation for extended time have that extended time. Once a student starts, they much complete in the alloted time.

            The students are on their honor NOT to cheat.

            There are Rules for Remote Instruction Exams/Quizzes which explain how to report exam/quiz answers---follows those rules.

              As explained above, it is ASSUMED that if you report the quiz answers for a lab that you have done the lab too and you do NOT need to make a separate report of having done it.

            Quizzes will usually only be posted on or near the day for the lab in the Lab Schedule.

            Quiz solutions will be posted after all students have complete: e.g., Quiz 1 will be posted at Quiz 1 solutions.

            To access the quizzes and solutions, the student will need the SUPER-SECRET username password which the lab instructor will email to the students. This is the same as for accessing the lab keys.

          11. Lab Final:

            The RMI Lab Final will be posted as per the Lab Schedule.

            The exam is a 2-hour exam will have 100 questions.

            Otherwise, the rules are the same as for quizzes which are also fully explicated at Rules for Remote Instruction Exams/Quizzes.
