Virtual synchronous labs for PSci 21 are essentially homework
assignments. Each week during which PSci 21 labs are scheduled (see
lab schedule below), each student will need to fill out the
worksheets at the end of the assigned lab writeup in the PSci 21 Lab
Manual. Each student will then need either to scan or to photograph
their completed worksheet, and then attach this (preferably as a single
pdf-format file) to an email. Each student will then need to send this
email to the student's PSci 21 lab instructor, by 11:59 p.m. on
Thursday of the week during which the lab will be run. Labs with
answers simply typed into email will also be accepted, for labs that
have answers can be typed into email. For example, drawings such as the
star maps at the end of the lab on the Mystery Constellations can't be
typed into email, so they need to be sent as email attachments.
In-person labs for PSci 21 will be real labs with lab instructors
available to help. In-person labs for PSci 21 will meet in the lab
classrooms (McLane 258 or 264) at the regular times (5:30 p.m. or 7:30
p.m.) on the days of the labs. PSci 21 lab instructors should discourage
students from attending any lab sessions other than the one in which
they are registered. We tried this in the past, and we found that it
just isn't possible to keep accurate records for classes as large as
PSci 21. Most in-person labs will be due as paper copies, to be filled
out and torn out of the PSci 21 lab manuals, by the end of each lab time
each week (which would be 7:20 p.m. for labs meeting at 5:30 p.m., and
9:20 p.m. for labs meeting at 7:30 p.m.).
Attendance: For in-person labs, attendance to all labs is
mandatory. You must attend the labs in the lab section in
which you are registered: exceptions will be made only by written
consent in advance of the instructor of the lab section in which you
are registered, and even then, only for compelling reasons (e.g. job
interview or illness documented by a physician's note). If you must
miss a lab for a compelling reason, the part of the lab grade that lab
would have counted will be voided, and the rest of the lab grade will be
counted as 100%. If you miss a lab without a compelling reason, or
without written consent in advance from the instructor, or if you attend
a lab other than the one in which you were registered without prior
written consent of the instructor of the lab section in which you are
registered, you will receive a zero for the lab. Any student with
three or more unexcused absences from lab will receive an F in the
entire PSci 21 course, which includes the lecture section.
If you are ill or an emergency arises beyond your
control and you cannot attend lab please contact your
lab instructor. Valid absences can be excused, and
that part of the grade voided, so that the remainder
of the grade will be counted as 100%. Still, even
for valid, excused absences, we can't give make-up
or advance labs. This is because most labs use
equipment (or views of the ever-changing sky) that
will only be available for the week they're scheduled
to be used.
Lab Safety: In-person astronomy lab sessions necessarily take place after dark, since the object of study is the night sky. If safety becomes a concern, the Campus Police provide an escort program. Radio-equipped, uniformed, trained escort officers will accompany persons to their destinations on campus during hours of darkness. Call 278-2132, or pick up an emergency phone to request an escort officer. Be sure to check their badges before going anywhere with them. The Campus Police also provide car battery assistance and other services, and can be reached in an emergency by calling 911.
Lab requirements: A flashlight is required for
map reading at observing sessions. Flashlights with
red filters are recommended, for night vision. A
clear plastic ruler and a copy of The Stars, by H. A.
Rey, are required as well. A scientific calculator
is highly recommended. Always bring your blue lab
manuals, and read the lab beforehand.

16 | May 9-12 | First Quarter (May 8) | No labs |
If a student must miss a class, it is the student's responsibility to get the notes from another student. It is also that student's responsibility to check on announcements made while absent. To do this, check this syllabus and the notes taken by another student: the instructor may not remember everything offhand.
Don't miss class. Listening to lectures and participating in discussions are much more effective than reading someone else's class notes.
This class will observe the five-minute rule: if I am five minutes late, you may go home. If you are five minutes late, you may go home. Don't be late: if you are, the instructor will require you to leave the classroom.
The PSci 21 instructor will not allow or accept assignments slipped under the office door, or delivered to McLane 173 (the Department of Physics office), or emailed, or faxed, because they get lost so easily. Any such assignments will be marked "late" and given zero credit, even if turned in on time or early.
Because PSci 21 is such a large class, the instructor will not be able to accept late work under any circumstances, even from students with a compelling reason to be late, such as an illness documented by a physician's note. In cases in which students do have a compelling reason to be late, and only in such cases, the instructor will mark missed work as "excused," which will mean that the part of the course grade for which that work would have counted will be voided, and the rest of the grade will be counted as 100%.
If there is any concern that an absence from class due to a university-sponsored event such as sports, theatre, or ROTC, or a family emergency, or that any other risk event such as traffic or a broken printer or computer drive might arise that would hinder any student from handing in assignments during the first five minutes of the class on the due date, the instructor highly recommends completing the assignment early. Assignments will not be accepted late for any reason.
Last-minute technical problems, such as broken printers or computer drives, happen when students wait until the last minute to complete an assignment. There is really no excuse for late work, because at a typing speed of 30-40 words per minute, it takes less than an hour to type and print even the longest PSci 21 assignment. Equipment failure at the worst possible time therefore isn't a plausible excuse, and will not be accepted as a valid excuse. There are computers and printers on campus that students may use, and students ought to make backups and print out drafts, to prevent this. If students don't even have an hour to spare to do their work, they have problems the PSci 21 instructor can't help.
If any student in PSci 21 turns in work early or at any other time that does not suit the student, the student may not go through the other students' papers, in order to find and recover their work. This is a violation of other students' privacy, and it is also a form of cheating, and is a quite serious matter: if a student does not stop going through the other students' paper immediately when told by the instructor, that student will get a zero for that assignment, and may also be punished for cheating (see below). The instructor will return the submitted paper to the student when the other papers in that stack are returned to the other students in the class.
If internet access is still a problem, students should come to the instructor's office hours or make an appointment to meet at some other time with the instructor, and the instructor will let these students use the instructor's computer. The instructor therefore won't accept excuses such as "I couldn't use the internet," or "My browser wasn't Java enabled."
Sorry, but the instructor cannot give make-ups for mid-term exams, nor can the instructor give mid-term or final exams in advance, not even for students who have legitimate reasons for being absent. Legitimate reasons for being absent include, but are not limited to, job interviews, illness documented by a physician's note, deaths in the immediate family that can be documented, or participating in University-sponsored activities, such as athletics, theatre, or ROTC. If any student must miss a mid-term exam, the student should remember that only the higher of the two mid-term exams will count. If any student must miss both mid-term exams, the part of the course grade for which the mid-term exam would have counted will be voided, and the rest of the grade will be counted as 100%.
If any student must miss the final exam for a very compelling reason, such as an illness documented by a physician's note, that student will receive a grade of I (incomplete) for PSci 21 for the semester. It will then be that student's responsibility to contact the university administration within the first 15 working days of the next semester to make the arrangements to remove the I grade. See the California State University, Fresno General Catalog for regulations concerning the Incomplete (I) grade. Only students who can document a very compelling reason for missing the final exam, such as an illness documented with a physician's note, will be eligible for incompletes: other students missing the final exam will get a 0% on the Final Exam.
If students want to know their mid-term grades, the mid-term exams indicate them reliably. During 2007 Spring, 83% of PSci 21 students got a grade for the entire course within one grade of what they scored on the higher of the two mid-term exams.
The instructor will be happy to fix any errors that occur in the grading. If after any errors are fixed, students still want to contest their grades, the students are required to do so in writing. This written request must be typed and must be a minimum of half a single-spaced page of 12-point type for exam or Final Exam questions, and a minimum of one single-spaced page of 12-point type for the overall grade. It is to be submitted one time, either to the instructor during office hours, or to the instructor's mailbox in McLane 173. See Grade Protests in the California State University, Fresno General Catalog: this must be done before the end of the fourth week of classes, during the semester immediately following the semester in which the contested grade was awarded.
DO NOT EVER copy and then paste anything with a computer, without enclosing it in quotes and citing a reference. This is plagiarism, and the first instance of it that the PSci 21 instructor or lab instructor finds will earn any student who does it a grade of F for the entire PSci 21 course.
DO NOT EVER take papers from the internet, and turn them in as your work. This is now easy for professors to detect, with www.plagiarism.org. Modifying someone else's paper slightly, or changing the word order, or stringing someone else's paragraphs together, even if they're cited, are also forms of plagiarism. Remember, always: you are responsible for anything with your name on it. Never turn in homework assignments that are exact copies of someone else's work. If you collaborate with other students, write up your results separately.
To prevent plagiarism, the instructor will be scanning both the paper titles and summaries and the research papers themselves. If the instructor finds any work that is plagiarized, the student will receive an F for the entire PSci 21 course. The instructor may also send the plagiarized work to the Dean and other university authorities (e.g. coaches) and recommend the student be expelled from the Universityor the degree be revoked, if the student has graduated. Do NOT plagiarize!
