COURSE RATIONALE:
The study of astronomy integrates many ideas from other fields of study such as history, mathematics, geology, chemistry, and physics. In addition, students learn about the Earth as a planet, the Sun as a star, and the Milky Way Galaxy as one of a trillion known galaxies. All of this helps one to have a better understanting of their place in the Universe.

ATTENDANCE REQUIREMENTS:
Students are required to attend all lectures, lab experiments, and telescope observing sessions.

Lectures:
Students are responsible for material covered in each lecture, for assigned homework, exercises, and for reading text assignments. Any assignment of a portion or all of a text chapter includes the summary at the end of the chapter. It also includes those self-test questions which pertain to the text assignment (answer keys are at the end of the textbook).

Lab experiments
There will be weekly laboratory assignments that will provide the student with hands-on experience with the concepts and ideas discussed in lecture. No make-ups are possible for missed lab experiments. Laboratory reports are to be completed before the end of the laboratory period. These reports will be graded on-the-spot and returned immediately to the student. Students may miss one lab experiment during the course without penalty. If all lab experiments are attended, and completed correctly, an additional 10 points are received.

Observing Sessions
Five telescope observing sessions will be at night held on the roof of the CLB building on the dates and times indicated in a separate observing schedule handout. Attendance is required at four of the five sessions. No make-ups are possible for missed telescope observing sessions. If all five telescope observing sessions are attended, an additional 10 points are received. Deductions will result if less than 4 sessions are attended according to the following schedule:

Sessions Attended Points Deducted
3 20
2 40
1 80
0 160

GRADING STANDARDS Grades will be based on the following:

  1. Quizzes and Homework
    There will be weekly homework assignments that will be handed out at the end of class on the last class day of the week. These assignments will be due at the beginning of class the following class period. No late homework will be accepted! In addition to the homework, quizzes will be given periodically throughout the course. These quizzes may come at any time during the week, so please keep up with the reading assignments and be regular and punctual in your attendance.

  2. Lab Experiments
    Each lab experiment is worth 10 points. One lab experiment may be missed without penalty during the course. An additional 10 points is received if all lab experiments for the course are performed correctly.

  3. Tests
    Four tests will be given on the dates indicated in the schedule worth 100 points each. Tests will cover material from lectures, lab experiments, and any other assigned materials.

  4. Article Summaries
    Four written summaries of a current magazine or journal article will be assigned over some topic in astronomy and will be worth 10 points each, 40 pts. total. Each of the five article summaried are due the day of the Unit Exam for each of the four Units. Summaries must be at least one-page in length, typewritten using a standard 12pt font. If the original article is online, provide the exact URL. If the article is from a magazine or newspaper, include the issue number and title of the article.

    Summary Element Point Value
    Formatting 2 pts
    Original Article Reference 2 pts
    Grammar and Spelling 1 pts
    Content Accuracy 4 pts
    Currency 1 pts
  5. Final Exam
    The final exam is comprehensive and will be worth 160 points.

Grades for the course will be computed on the above items as follows:

Assignment Points
Homework Assignments 120
Inclass Quizzes 60
Twelve (12) Lab Experiments 120
Four (4) Unit Exams 400
Four (4) Article Summaries 40
Final Exam 160
Total 900

Letter Grades are determined as follows:

90-100% = A
80-89% =  B
70-79% =  C
60-69% =  D
below 60% = F

GUIDELINES FOR SUCCESS IN THE COURSE:

  1. Students can expect the Astronomy Course to be just as demanding as a course in physics, chemistry, or geology. Many of the principles from these other science courses will also be encountered in astronomy.
  2. As a guideline, students are expected to spend two hours of study time each week for each credit hour of class. Thus approximately eight hours of preparations should be spent each week. This includes reading text assignment, working homework problems, and reviewing material covered in class and lab exercises.
  3. It is essential that students read the textbook assignments before coming to class, not only to facilitate note-taking, but also to better understand the material covered in class.
  4. Although the math used in the course does not go beyond the high school level, it likely will be necessary for students to review math fundamentals in order to grasp scientific principles used in the course. Both the text and the math reviewed in the course should be helpful in this regard.
  5. Although grades are not based on classroom attendance, students are strongly encouraged to attend every class. Because of the extent and diversity of the subject material, and the pace at which this material is covered, missing class is very detrimental to success in the course. Students are responsible for obtaining class material and instruction missed due to absence.
  6. Students should keep all graded materials that have been returned by the instructor so that they can be used, if necessary, to reconcile the final course grade.

GENERAL COMMENTS:

Withdrawal Policy:
If a student withdraws from the course, appropriate forms must be submitted by the student to the Admissions Office. Otherwise, the student will be kept on the class roster and receive a grade for the course. Time restrictions and procedures for withdrawing from a course are found in the college catalog and credit class schedule for the appropriate semester.

Attendance Policy:
It is the policy of JCCC that punctual attendance at all scheduled classes is regarded as integral to all courses and is expected of all students. Students under obligation to participate in jury duty, required military duty, and generally recognized religious observance, and/or activities where they are required to represent the college must give written notice to the faculty member at least one week in advance of the observance. Questions on whether a religious holiday is recognized and/or an activity is college-sponsored should be directed tot he vice president of Student Services and/or the Student Affairs Committee. Students shall be accorded the opportunity to independently make up course work or work of equal value for the day(s) the event was scheduled and to take a scheduled exam at an alternate time determined by the instructor. Failure to provide timely written notice may result in loss of this opportunity. Students should be aware that the quality of the learning experience may suffer as a result of the absence if the course work is not made up.

Academic Dishonesty Policy:
Academic dishonesty will not be tolerated and will be subject to the appropriate penalties. Please make every effort to avoid dishonesty or the appearance of dishonesty in all course activities. Penalties may include, but not limited to a zero grade for the activity, failure in the course, or dismissal from the college.

Counseling:
Students are encouraged to meet with the instructor to discuss any problems they are having with the course. While office hours have been set aside for student discussions, any mutually agreeable time for a student-instructor meeting is satisfactory. Students are also encouraged to make use of the Science Resource Center where free tutors are available in CLB 112. Tutor hours for the current semester are posted outside of the SRC.

Safety:
Students are expected to conduct themselves in a safe manner at all times. Unsafe activities are not allowed. Students should realize that their own safety, as well as that of others around them, is each individual's responsibility. Students performing laboratory experiments are responsible for planning and conduction operations in accordance with institutional chemical hygiene procedures, and for developing good personal chemical hygiene habits. Additional safety rules (when required) will be attached to laboratory handouts.

Disability Statement:
Students in this course who have a disability that may prevent them from fully demonstrating their abilities should contact the instructor and Access Services as soon as possible to discuss accommodations necessary to complete the course requirements.
