Course Objective

The overall goal for this course is for the student to understand how we know what we know rather than memorizing random facts. Astronomy 121 is a combination of ancient Greek philosophy, biology, physics, geology, and of course astronomy. You can’t help but learn interesting tidbits of information. However, just memorizing information (and cramming for tests) will not give you success in this course. The tests and assignments are designed to get you think about the material. And well…thinking is good! We need more intelligent and creative thinkers in our ever-growing population.

 

It is my own goal to keep this class as interactive as possible. There is a lot of material to get through, but I’d rather sacrifice breadth of content if we get into some interesting discussions about the material. Please feel free to ask questions about planetary topics or any astronomy topic. I will strive to ask as many clicker questions as possible to keep you engaged as I lecture.  No one (including me) wants to sit through 2+ hours of someone talking without any break.

 


Required Materials

§  There is no textbook for the course, but you are welcome to use one for reference. All reading materials are online.

§  You need to purchase a clicker through the bookstore and register the number on blackboard


Lectures

You have two sources of reading materials for the course. Consider the stuff listed under “reading material” to be the textbook for the course. The other source is my power point presentations given in class. I will use both the reading material and the ppts to conduct the lecture.  You should aim to glance over the material prior to class and read the lectured material thoroughly after class. Because everything is accelerated during the summer, you will need to read the material everyday to keep up with the class.

 

Clickers!

Each day will consist of at least a lecture interspersed with clicker questions. It is crucial that you bring your clicker to class and make sure that it is working properly. I will do a roll call at the beginning of the first few classes to register your clicker, if you haven’t done so on blackboard.

 Except for the first day of class, I won’t accept hand-in pieces of paper for clicker answers because you forgot your clicker or you discovered it needs new batteries. The whole point of using them is so that I can see almost instantly what the class understands and doesn’t understand.  Handing in a piece of paper at the end of class with clicker answers doesn’t help you or me. We will use these every day (except test days) and these will be you participation grade, so bring them and an extra set of batteries!

 

Grades

The breakdown for your grades is the following:

15% participation via clickers

20% Midterm

40% homework and in class activities

25% Final

 

All the grades are curved in this class. Usually, it works out to the following distribution of grades. If the class average is significantly different (over 5%), I will adjust the curve accordingly.

95% and above = A+
90-94% = A
86-89% = A-
82-85% = B+
76-81% = B
71-75% = B-
65-70% = C+
57-64% = C
48-56% = C-
Below 48% = D

 

Grades for the course are posted on blackboard.

 

Participation

Again, to get full participation you need to attend all the classes and answer (correctly or not) 75% of the questions.  Questions can be asked throughout the lecture (beginning, middle and end) so be sure to stay for the full class.

 

Homework

There will be 3 homework assignments and a few in-class activities worth 40% of your total grade. Therefore, it is important that you do the homework and come to class. Sometimes I’ll ask you to turn in in-class work the day that we do it, and other times, I may ask you to attach it and turn it in with the upcoming homework assignment that’s due. See the schedule below for due dates. Most of the homework is designed to reinforce concepts discussed in class as well as to make you apply some of the information to problems.

 

Tests

You will have a midterm and a final. Both are a blend of short and long answer and possibly some true/false and matching.  Unless you are significantly ill and have some sort of documentation, there are no make up tests. Vacation plans aren’t considered an excuse. In fact, missing any of the classes is not recommended due to the brevity of the term and the fact we do a lot of work in class.  The final is comprehensive and on Friday Aug 12 at 3:15pm.  Note: this is not a regularly scheduled class time. See the schedule below for test dates.

 

Students and Disability Services

If you require extra assistance, such as notes, extra time on assignments, exams, etc., please contact me before or after class and provide the appropriate documentation from disability services as soon as you can. You may also email me if you are concerned about confidentiality, and hand the form in to me at my office. Please don’t hesitate to communicate with me directly, because most needs vary from student to student and sometimes I need a little more information to understand what works for you.  

 

FAQs and Rules for this class

Late Policy: Late homework is accepted but loses 10% of the total assignment points for each day they are overdue, and yes this includes weekends.

 

Extra Credit: There is no extra credit in this class.

 

Make up tests: Due to the brevity of the course, there are no make up tests unless you have a note from a doctor or other relevant authority figure. You can’t make up the final, period. 

 

Redos: There are no “redos” for any homework or test.

 

Laptops/phones/Distractions: If you are distracting me because you are either talking, texting or watching videos on your computer, I will let you know and ask you politely to stop or leave.  Even though laptops are useful, especially when following the lecture notes, I’ve noticed in the past that students rarely used them for tasks pertaining to the lecture (youtube videos, facebook, etc). They are a major source of distraction for you and everyone around you unless you are using them for lecture. Yes, you are effecting others ability to learn the material as well. If you need to check your Facebook status constantly or watch MLB games, then don’t bother coming to class. I really hate texting and surfing on phones as well. If you need to text, do it as discretely as possible. Also if someone is bugging you with aforementioned items, I support you telling them to stop it. I can’t police every person in the class and I shouldn’t have to because this is college and you’re all adults who are responsible for your own academic success.

 

Coming and Going: I understand if you have to get up and use the restroom or get some water because you are coughing. But having people get up, leave and then come back and then leave and return is really annoying. Please try to keep this at a minimum. We will have a 10 minute break about an hour into the lecture.

 

Final Test Date: The test will be offered at the scheduled time (Willamette 100; 3:15 pm Friday August 12h). You can’t take it earlier or later, so make your vacation/work plans accordingly. According to school policy, if you have more than 3 (read 4) finals in one day you can reschedule the final. If this is the case for you, and you asked your other professors first and you have proof of having 4 finals (copy of transcript or schedule) then I will reschedule the test for you only. This will also be an essay-type exam.
