Recommended Class Textbook:
The Cosmic Perspective Fundamentals, by Bennett, Dohahue,
Schneider, Voit. You can get the new
third edition (about $90)
the second edition (<$25), or even the
first edition (so cheap!), your choice. All you
need is the hardcopy textbook. This is the
shortest Astro book on the market, and I recommend that you to read it
cover to cover over the course of the semester! A free alternative
textbook is also available as a PDF from openstax at
https://openstax.org/details/books/astronomy.
Class Web Page:

Packed full with course information, supplementary readings, and interactive programs
to make ASTR101 fun and to help you learn. Follow astronomy in the news
and see cool space pictures and movies!
Class Meetings:
Lectures
meet in PHYS 1412 on TuTh from 11:00am to 12:15pm. Lectures are led by
the professor and will include demonstrations, slides, videos etc.
Discussion Sections and Labs
meet in times listed below starting the week
of Sep. 5. Discussion sections and Labs are led by graduate student
Teaching
Assistants (TAs). Both weekly meetings provide a smaller
and more informal environment for further developing the material
taught in class. The TAs will also answer questions about the lectures
and reading and will hold review sessions before exams. More details on Section and
Lab Policies will be provided during the first meetings.
Course Description:
Welcome to Astronomy 101! You are about to embark on an ambitious
project - to survey our known Universe in one short semester. We hope
that you find this course enjoyable and walk away with a better
knowledge and understanding of the universe that we live in. With that
goal in mind, the course attempts to focus on major concepts in
astronomy and where possible tie those concepts into issues relevant
to your life. For example, global warming, an important worldwide
issue, is also central to understanding the differences between the
environments of Venus, Mars, and Earth. At a more philosophical level,
understanding how our universe works and how planets, stars, and
galaxies are formed gives us a better perspective on our place in the
universe and how special planet Earth is to our continued survival.
Most of you have chosen this course to fulfill your science
requirement (see GENED Requirements
below). GENED courses are designed to ensure that you will take a look
at several different academic disciplines and the way they create and
analyze knowledge about the world. We will introduce you to ideas and
issues that are central to a major intellectual discipline and involve
you actively in the learning process. Please take advantage of the
opportunities this course offers!
Course Expectations:
Attendance: In order to succeed in this course, I
expect you to
attend all lectures, discussion sections, and labs. This is
very important! The material on the homeworks and exams are based upon
the material covered in the lectures, the text, discussion sections,
and labs. If you have to miss a scheduled class meeting, be sure to
look at another student's notes and make sure that you understand what
was covered. See me or the teaching assistant if you have questions.
There will be times during the semester, in both lectures and
sections, when we will ask for written responses to questions. Your
written answers will count towards your grade in the class.
Preparation: I expect you to be prepared to work.
You will understand the lecture more easily if you preview the reading
assignment. A more careful reading is recommended after lecture. You
should study your class notes sometime before the next lecture to make
sure that everything is clear. I encourage you to ask questions in
class, in discussion, in lab, during office hours,
and over email.
Study Habits: Study wisely and ask for help if you
need it. If you just cram the night before the exam, you probably
will not do very well. It is better (and easier) if you keep up with
the material on a daily basis. If you have questions, please see me
or one of the TAs. We are here to help you learn.
Grading:
I grade on a point scale with different assignments weighted as shown
in the table. A description of each of these components is contained
in this syllabus.
ASSIGNMENT |
Syllabus Cover |
Homework |
Section |
Labs |
Exam I | Exam II |
Final |
Total |
POINTS |
10 |
60 |
80 |
150 |
100 | 100 |
200 |
700 |
Letter grades will be assigned based upon your curved cumulative
score. Grades for some discussion sections may be adjusted slightly
so that the average grade given by each TA is similar. Here is how
your grade will be determined from your point total in the class.
Letter Grade |
A |
B |
C |
D |
F |
Points Needed |
630-700 |
560-629 |
476-559 |
385-475 |
0-384 |
Percentage |
90%-100% |
80%-89% |
68%-79% |
55%-67% |
0%-54% |
The point scale makes it possible for everyone in the class to do
well. For example, if everyone scores above 80% in the course, you
would all receive either a B- or better letter grade. I do use +/-
modifiers - you will get a "+" if you are in roughly the upper 1/3 of
students with the same letter grade and a "-" if you are in the lower
1/3. I may adjust the number of points required to get a given grade
depending on the class averages; however, any adjustment will make it
easier to get a given grade, never more difficult. You can my
current estimate of your grade from the class ELMS site as the semester
progresses.
Top three ways to get a good grade in
ASTR101: 1) Attend all ASTR101 meetings, 2) Do all ASTR101
assignments, 3) Read the ASTR101 book.
Also important to improve your learning in ASTR101:
go over your returned assignments and any solution sets carefully
within a day or two of when they are returned to you. If you are
unsure about why something was marked wrong or you believe that it was
incorrectly marked wrong, please contact your TA promptly. Grading
will be reconsidered for only a reasonable
time after the assignment is returned to you, typically 7-10
days.
Midterm Exams
There will be two in-class 75-minute examinations which will be held
in PHYS 1412 on Thursday, October 6 and Thursday, November 17. These
exams are closed book with no notes, no calculators, and no other
electronic devices allowed. You will only be allowed to leave the
classroom at a few specified times, and once you leave you cannot
return to your exam. Each exam will consist of 25-40 multiple choice
questions and three or four essay or problem solving questions. These
exams are incremental (i.e., non-cumulative) checkups on how well you
have learned the material. The schedule of lectures included in this
syllabus shows what material will be covered on each exam. Please
bring only a pencil and your ID card to both midterms and the final.
If for whatever reason, the University is officially closed on the
exam date, the exam date shifts to the next lecture date.
Final Exam
According to University rules, the final exam for this course
will be held on Wednesday Dec. 14 from 8:00 am to 10:00 am in PHYS
1412. This final exam is cumulative, that is, it will
cover all material discussed in this course. However, since
chapters 10-15, HW 5-6, and labs 10-11 will not be covered by the
midterm exams (see Lecture Schedule),
this material will be more heavily weighted. The final will
include multiple choice, essay and problem solving questions with the
exact combination to be determined.
This exam is also closed book with no notes and no calculators
allowed. Please bring a pencil and your ID card to the final.
Missed Exams
If you are not able to take an exam due to illness or other legitimate
reasons (as outlined in the Academic Info section of the schedule of
classes) and you wish to take a make-up exam, you must
1) contact me by email before you miss the
regularly-scheduled exam and
2) submit a valid written
excuse for your absence within one week
after the regularly-scheduled exam.
Exams are Major Scheduled Grading Events and, accordingly, proper
documentation will be required if you wish to make up a missed exam.
Make-up exams will typically be given within one week after you submit
the valid written excuse. The make-up exams will consist entirely of
essays, problems, and short answer questions, and may also include
oral questions asked by the professor.
If you miss the final exam and have a valid written excuse,
you must arrange for a make-up final within 48 hours after the
scheduled exam. The make-up final, like the make-up midterms, will
have no multiple choice questions.
Discussion Sections and Labs
Your weekly hour-long discussion section is an integral part of this
course. The sections are run by the TAs, with just general guidelines
from me; they will normally include preparing you for lab, review of
lecture material, presentation of problems and material not covered in
lecture, exercises and quizzes etc. These sections serve as a forum to
enhance your understanding of the course material. Your TAs are an
excellent resource; get to know them and use that resource!
Exams and other paperwork will be returned to you by your TA. Please
attend all your discussion sections and labs. If for some reason you
have to miss one of these meetings,
talk to your TA for options for making up the work.
Understanding laboratory techniques and reaching conclusions based on
careful observations is a hallmark of scientific inquiry. Your weekly
2-hour lab is an important part of this course that provides you with
the opportunity to think like a scientist. Our goal is that you leave
ASTR101 at the end of the semester with critical thinking skills that
will allow you to better appreciate science in the news and elsewhere
that you encounter it.
Be sure to attend the discussion section and lab combination for which
you registered. The only way to switch sections is through the
registrar's office;
unofficial changes are not allowed. Memorize your
section number and put it on everything that you turn in.

Copying from another student's lab - from our class or
another - is academic dishonesty and will not be tolerated in
this class (see Academic Integrity below).
The Prof. and the Teaching Assistants all hold office hours that are
open to everyone. There is someone available for several hours each
day of the week - we are here to help! When contacting us by email,
always be sure to put "ASTR101" in the subject line to ensure that
your email is not overlooked. If you cannot make office hours because
you are feeling ill or for another valid reason, please contact us for
Zoom options.

Homeworks
There are a total of six homeworks in this course. All homeworks will
be posted and turned in on ELMS. Homework solution sets will also be
posted on ELMS.
All homeworks must be typed and turned in at 11:59 pm
on the due date. Homeworks turned in after this will be considered
late and docked at least 20%. Homeworks may
not be turned in by email. If you experience a valid
emergency, you must write your TA an email or leave them a voice mail
message before the assignment is
due, telling them why you will be late. Occasionally,
you might need to upload a PDF to ELMS. But computer problems are not a
valid excuse for being late; just ask a friend or your TA for help if you need it.
Although you may discuss the homework problems with your friends,
the final writeup
must be in your own
words.
Copying from anyone else's
homework, copying from a website, copying from the book, copying from another printed or online source, or allowing anyone to copy your
homework is academic dishonesty (see Academic Integrity below) and is unacceptable in
this class. If you consult a reference other than the course text,
please acknowledge it in your homework - this includes
websites!
Extra Credit
There are many ways to earn extra credit in this class:
- Attend Class: I will frequently ask questions worth bonus points
during lectures.
- Do the Extra Credit questions on each homework assignment.
- Fill out the ASTR101 class evaluation in October.
Please do not ask for other extra credit opportunities.
Special Circumstances
Students with a documented disability should let me know as soon as
possible (preferably on the first day of class) so that appropriate
academic accommodations can be made.
The academic community at the University abides by a Code of Academic
Integrity. Acts of academic dishonesty include cheating, fabrication,
facilitating academic dishonesty, and plagiarism. Activities
including, but not limited to, cheating on exams or quizzes, copying
homework answers from a website, a friend or a book, allowing your
homework or paper to be copied, and submitting forged excuses for
absences are violations of this code. Academic Dishonesty
hurts the whole University of Maryland community - if you
are aware of
an incident in ASTR101, please report it to one of the TAs or me,
anonymously if you wish. If we suspect that a serious incident of
academic dishonesty has occurred, we will turn the case over to the
Student Honor Council to investigate and resolve. If the suspected
party is judged 'responsible' for the act(s) of academic dishonesty,
the normal sanction is a course grade of 'XF' on the student's
academic transcript which denotes failure due to academic
dishonesty. This is far worse than an F. More information can be found
on the web at
https://academiccatalog.umd.edu/undergraduate/registration-academic-requirements-regulations/academic-integrity-student-conduct-codes/; pay particular attention
to the links for students. Also, take a look at my
Academic Dishonesty FAQs.
We are very serious
about this.
ASTR101 is intended for non-science majors and requires no more than a
modest, high-school level science and math background. This course
satisfies U. Maryland's requirement for a
lab natural science course. To satisfy the requirement for
a non-lab natural science course, you might wish to
consider ASTR100. Note that you cannot get credit for both
ASTR100 and ASTR101. Please be sure that you have chosen the
correct course.
