4. Syllabus

My syllabus is everything stated at Syllabus along with the following additions and notes. Please read Syllabus before reading the following.

4.1. Format

This is a three-credit course that meets for 75 minutes twice per week. I use active learning techniques during class. After presenting a major concept I will pose a question which you will think about, write about, discuss with your neighbor, and then possibly present your answers.

Be prepared to think and work in class!

Typical Schedule


  • Mostly lecture and some in-class activities.
  • Homework is due at start of class.


  • Mostly in-class activities.
  • Quiz near the start of class. Quiz covers previous lecture and homework that was turned in at the start of class.
  • Homework is assigned at the end of class and is usually an extension of the in-class activities.

4.2. Grading

Partial credit is given on all problems provided work is shown. When we grade, we look for a correct answer. If the answer is not correct, we look for evidence that you understood something about the problem. The more evidence that is provided, the more partial credit is given.

We drop the lowest quiz and homework grade. The only time an additional homework or quiz grade will be dropped is if the student provides documentation for the absence.

4.2.1. Weighting

  • Quizzes 10% (lowest quiz grade dropped)
  • Homework 30% (lowest HW grade dropped)
  • Midterm 30%
  • Final exam 30%

Final grade scale: 93 and above=A, 90-93 = A-, 80-83=B-, 83-87=B, 87-90=B+, 70-80=C, 60-70=D, 59 and below=F.

4.2.2. Attendance

I do not penalize students for missing class and I do not take attendance. I have found that the above grading policy sufficiently penalizes students that frequently miss class. (My observation is that if a student misses more than two weeks of classes it is very difficult for them to earn a grade higher than a B-.)

4.2.3. Quizzes

Quizzes will be used for two purposes:

  1. To ensure that you are prepared for the in-class work.
  2. To ensure that you understood (and did not just copy) the homework.

4.2.4. Homework

  • There will be a weekly homework that is due one week after it is assigned. Homworks must be turned in before class starts.
  • We will partially work many problems in class that will be due the following week (they will seem very difficult if you don't attend class!).
  • I am serious about the above. The homework problems are not simple multiple choice questions. To solve, they require a synthesis of multiple concepts covered in class.
  • Most homeworks will be hand-written in the first half of the semester.
  • Most homeworks will be turned in electronically in the second half of the semester.
  • Late homework will not be accepted. I will drop the lowest homework grade.
  • It is OK to collaborate with one or two other students on homework problems. If there appears to be evidence of one student copying another, the students involved will be asked to meet with the instructor and/or T.A.

Homework questions will usually consist of calculations, short answers, and computer programs. The questions are designed to test a student's understanding of the course material. When applicable, the student isstronglyencouraged to write outboth the solution and the step-by-step solution logic in their homework responses, so that instructors may assess the student's overall approach to and understanding of the assigned problems. Credit will be assigned on student homeworks based upon whether or not the student's solution is correct (approximately 50% of the score), and also whether the student's solution logic is correct (approximately 50% of the score).

4.2.5. Exams

  • A midterm and final exam will be given in the class to test comprehension of the topics covered in the lecture, discussions, and homework.
  • The exam will include short answers, multiple choice, and simple discussion questions. The questions will be based on concepts covered on the homeworks and in the in-class questions.
  • Sample midterm and final exams will be provided approximately a week before the date of the actual exam.
  • There will be no surprises on the exam. The exams are designed so that students who can successfully solve all of the problems on the sample exams, within the allotted time per exam and without notes will earn, at worst, a B on the actual exam.

4.3. Important Dates

4.4. Office Hours and Email

  • Office Hour: 12:00-14:00 on Monday and by appointment (rlohner@gmu.edu). My office is in room 103C of Planetary Hall. I usually arrive at class 10-25 minutes early. I will arrive earlier if students start asking me questions before class.
  • Email questions:
  • Extra help: Monday from 2-4pm in Research Hall room 91 or 92. LAs will be available for questions.
  • Extra help: Contact ??? to set up an appointment if you can't make the office hour or the Monday extra help session.

Important: If your email is not set up to show your full name in the "From" line, please include your first and last name in your email so that I know who you are. To change the display name in Mason Live, go to options drop-down menu, click on "See All Options", then click on "Edit" on the Account Information page, and a window pops up where you can change your name and display name.

4.5. Exams

  • I rarely give make-up exams. However, special consideration will be given if the student (1) has completed all of their homeworks on time and (2) provides compelling evidence that they missed the exam for reasons that were beyond their control.
  • At least one class period will be used for exam review and the results of the exam will be discussed within a week after the exam was given.
  • I always give sample exam problems for students to use to prepare for exams. These sample exams should be considered as the equivalent of a study guide. The actual exam is written so that (1) if you _understand_ the principle(s) required to solve the problems on the sample exam, the actual exam will not be difficult, (2) if you only attempt to memorize the questions and answers to the sample exam, you will perform poorly on the actual exam.

4.6. Honor Code

I am generally approachable, reasonable, and patient with anything involving undergraduate students.

I am always stubborn, aggressive, and irritable on anything involving violations of the honor code, especially on exams.

Although my primary teaching responsibility involves teaching science-related subjects, I believe that an auxiliary responsibility of a college professor involves giving lessons related to ethical and honorable behavior.

It is OK to collaborate with one or two other students on homework problems. If there appears to be evidence one student copying another, the students involved will be asked to meet with the instructor and/or T.A. before any honor code actions are initiated.

4.7. FAQ

  • Do you use BlackBoard? No. All information about this course is at http://cds130.org/ or is sent to you via email.
  • Textbook? None required. All of the information that you need is available from http://cds130.org/.
  • Software? All software will be free. Outside of class you will have access to the same software on the classroom computers.
  • How much math? Math makes many students anxious. I know this. This class requires calculations, but the calculations are much different than the ones you typically do in algebra, trig, and calculus.
  • How much programming? We gradually build you up to being able to write your own programs. We do not assume any prior programming experience; we assume only that you have worked with Excel. After the fourth week, you are typically asked to write one or two small programs per homework - about 50% of the total grade.
  • What kind of problems will we be able to solve?
Glad you asked. Here are a few of the problems students worked on later in the semester Tumor | Antialias. We are working on more (in particular, a Neuro-specific project that useshttp://www.hiit.fi/neuro/images) and will take requests.
  • Do you give credit for class participation? I do not give points for class participation. Students that do not participate will naturally do worse. I find that giving points for class participation makes the best students suffer because they spend more time thinking about what they need to do to enhance their participation grade and less time thinking about the problem under discussion.
