## Homework Policy:

DO IT! There will be approximately four homework assignments. It is a key component to your learning of the material, so DO IT! Each homework will be posted on the course web page the week beforehand.

## Written Homeworks:

The written homeworks contribute towards your homework grade. You are expected to complete homework questions requiring proof **only by consulting your classmates, the course materials, or your professor**, and ** NOT through internet searches** nor by contacting students who previously took this class. I expect

**all solutions to be fully justified**, unless otherwise noted. What this means is that you should be writing in full sentences enough to convince me that you know how to solve the problem completely. Each of the problems will be graded on the following scale.

4 or ✓ +(110%) A well-written homework solution that hits on all the main points.

In other words,Perfect!3 or ✓ (85%) A well-written homework solution that contains most of the main ideas needed to solve the problem completely. 2 or ✓ -(60%) A homework solution that contains some of the main ideas but is not complete. 1 or ✗ (35%) A very partial solution or a good start. 0 or 0 (0%) No work, a weak start, or an unsupported answer

I require you to follow some relatively strict guidelines for homework submission. It is especially important that your homework be legible and clearly presented, or **I may not grade it**.

It is important to learn how to express yourself in the language of mathematics. In the homework, you should show your work **and** explain how you did the problem. This is the difference between an **Answer** and a **Solution**. It should be obvious to the person reading the homework how you went about doing the problem. This will often involve writing out explanations for your work in words. Imagine that you need an example to help refresh your memory for another class in six months!

A guiding principle that I suggest you follow is "Be precise and concise." That is, you should take great care to write your solutions so that you leave no ambiguity to what you mean and that you write no more than is necessary.

## Late Written Homework:

I understand that outside factors may affect your ability to turn in your homework on time. During the semester you will be allowed five total grace days. If a homework is due on Wednesday and you turn it in on Friday, this counts as two of your five grace days. Once you have zero grace days, **I will not accept late homework**. If you are not planning to be in class, let me know and get it to me **beforehand**. This is your responsibility. I can accept clearly scanned homework by email, but I will likely expect a physical copy at the next class session.

## Study Groups:

An important component of your learning in this class is through study groups. Study groups allow you to learn the intricacies of the material; discussion of problems often lead to better understanding and new and more efficient ways to solve the problems. One of the best ways to learn something is to explain it to someone else; misunderstandings that you never knew you had will appear under someone else's questioning! In addition, seeing that others also struggle with the material helps to put your own level of understanding in a better perspective and will hopefully reduce some of your anxiety. If you can not find a study group, e-mail me so that I can help you get involved.

Most importantly, I assume that you will be working in groups when I make up the homework assignments. At the beginning of the semester, the problems will seem easy enough to plug and chug on your own, but as the term progresses the questions become quite complex indeed. **Study groups good. Copying solutions bad.** When a group works on a problem, everyone can participate. But when you write up the answers to the problems, **write it up in your own way**. *I will take off points from all parties if multiple solutions are the same.* **Be sure to include an acknowledgment to your groupmates on your homework.**

## Exams:

There will two exams during the semester. They will be a class period in length and no calculators, cell phones, or study aides are allowed (or are necessary). There will be **no make-up exam** except in the case of a documented emergency. In the event of an unavoidable conflict with the midterm (an athletic meet, wedding, funeral, etc...), you must notify me at least one week before the date of the exam so that we can arrange for you to take the exam **BEFORE** the actual exam date.

## Final Project:

In addition to the homeworks, you will be working in a group of two or three students, where you will use the techniques from class to model a real-life situation of your choosing. More information can be found HERE.

## Grading Scheme:

Your grade will be based on written homework, class participation including homework presentations, your course project, and the two exams. Each component of your grade is calculated independently; then all pieces are combined using the following weighted average.

Class Participation: 10% (This entails regular attendance, staying engaged, and asking questions)

Written Homework: 15%

Exam 1: 20%

Exam 2: 20%

Written Project: 25%

Project Presentation: 10%

## Office Hours:

I am happy to help you with your homework and other class-related questions during my office hours. I have official office hours as posted on my schedule. In addition, you are welcome to make an appointment or stop by my office in Kiely Tower Room 606 at any time. (You can call 718-997-5964 to see if I'm there.)

## Cheating/Plagiarism:

DON'T DO IT! It makes me very mad and very frustrated when students cheat. Cheating is the quickest way to lose the respect that I have for each student at the beginning of the semester.

Both receiving and supplying the answers on an exam is cheating.

Working together on homework is __encouraged__ and is certainly not considered cheating. On the other hand, **copying someone else's homework solutions IS cheating.**

**Copying content from online or offline sources and passing it off as your own work IS cheating**. The work you turn in for your projects must be your own and include citations of any materials that you use or inspired your project. On the other hand, it is __encouraged__ to download/explore/use other people's source code to learn about what is and is not possible to do using Mathematica.

I take cheating very seriously. If you cheat, you will receive a zero for the homework/exam and I will report you to the academic integrity committee in the Office of Student Affairs to be placed on your permanent file. If you cheat twice, you will receive a zero for the class.

## Accommodations for Students with Disabilities:

Students with disabilities needing academic accommodation should register with and provide documentation to the Office of Special Services, Frese Hall, room 111. The Office of Special Services will provide a letter for you to bring to your instructor indicating the need for accommodation and the nature of it. **This should be done during the first week of class.** For more information about services available to Queens College students, contact the Office of Special Services (718-997-5870) or visit their website (http://sl.qc.cuny.edu/oss/). If you need special accommodation for an exam, you MUST contact me **at least one week beforehand**.

## Course Evaluations

During the final four weeks of the semester, you will be asked to complete an evaluation for this course by filling out an online questionnaire. Please remember to participate in these course evaluations. Your comments are highly valued, and these evaluations are an important service to fellow students and to the institution, since your responses will be pooled with those of other students and made available online, in the Queens College Course Information System (http://courses.qc.cuny.edu). Please also note that all responses are completely anonymous; no identifying information is retained once the evaluation has been submitted.

## Technical Support

The Queens College Helpdesk (http://www.qc.cuny.edu/computing/, (718) 997-4444, helpdesk@qc.cuny.edu) is located in the I-Building, Room 151 and provides technical support for students who need help with Queens College email, CUNY portal, Blackboard, and CUNYfirst.
