Projects

To give you experience solving larger, more difficult problems involving multiple concepts, there will be three computer-based projects assigned during the semester. Suggested software is Matlab, although Mathematica and Maple may be used. These projects are required of all students registered in APPM 2360.

PDF copies of each lab, and any additional materials related to the projects can be found in the table below or on D2L.

General Information about projects

There will be three projects assigned during the semester. The goal of the projects is to combine multiple concepts and solve difficult problems. The projects will give you some experience in the practice of modeling and solving problems using computer software. The projects also give you several chances to show off your verbal prowess. The overall quality of the lab reports will be taken seriously. They will be graded for presentation, spelling, grammar, clarity, and insight, as well as mathematical correctness.

For each project, students should work in groups of three. Only one report per group is necessary and all members of the group will receive an identical grade. The names, ID numbers and correct recitation section numbers for each group member must be included in the report. If any of this information is missing, your grade may not be recorded! The regrade policy is the same as for exams, except that lab questions should be directed to the APPM 2460 lab course coordinator(s).

The projects will be submitted electronically via D2L by 5pm on the due date. Late labs will not be accepted or graded and a score of zero will be given to any late lab. Further details will be given later in the semester.

Several OIT labs are also available for your use - ECCR 244 in particular. You are free to use whatever computer system you feel most comfortable with, although it may be beneficial to use Matlab since the TAs will be expecting Matlab code during their office hours.

Students can download a copy of Matlab for their use by going to link given below under the "Resources" section.

Writing Guidelines

Your report needs to accurately and consistently describe the steps you took in answering the questions asked. This report should have the look and feel of a technical paper. Presentation and clarity are very important. 

Here is an https://www.colorado.edu/amath/sites/default/files/attached-files/sampl… lab with illustrations of a https://www.colorado.edu/amath/sites/default/files/attached-files/good_… lab report which would receive high marks and a https://www.colorado.edu/amath/sites/default/files/attached-files/bad_s… lab report that would receive low marks.  Note that in the "bad lab report", all questions are technically answered, but not in the form of a lab report.

  • Absolutely make sure your recitation number is on your submitted report.
  • Start with an introduction that describes what you will discuss in the body of your document. A brief summary of important concepts that you will be using in your discussion could be useful here as well.
  • Summarize what you have accomplished in a conclusion. No new information nor new results should appear in your conclusion. You should only review the highlights of what you wrote about in body.
  • Always include units in your answers.
  • Always label plots and refer to them in the text.
  • The main body of your paper should NOT include lengthy calculations. These should be included in an appendix, and referred to in the main body.
  • Labs must be typed. Including the equations in the main body (part of your learning experience is to learn how to use an equation editor). An exception can be made for lengthy calculations in the appendix, which can be hand written (as long as they are neat and clean), and minor labels on plots, arrows in the text and a few subscripts.
  • Your report doesn't have to be long. You need quality, not quantity of work. Of course you cannot omit any important piece of information, but you need not add any extras.
  • DO NOT include print outs of computer software screens. This will be considered as garbage. You simply need to state which software you used in each step, and what it did for you.
  • You must include any plot that supports your conclusions or gives you insight in your investigations.
  • Write your report in an organized and logical fashion. Section headers such as Introduction, Background, Problem Statement, Calculations, Results, Conclusion, Appendix, etc... are not mandatory, but are highly recommended. They not only help you write your report, but help the reader navigate through your paper, besides giving it a cleaner look.

Project Submission Guidlines

You and your group will submit your project on D2L, in the appropriate dropbox (you can find these under the "assessments" tab in D2L) Your group must:

  • Submit your project in pdf format. When word documents are uploaded to D2L, the equations in them are commonly jumbled around.
  • Submit the code used for your project (a .nb file for Mathematica, .m file for MatLab, etc).
  • Have only ONE group member submit the project. Having multiple people in your group submit the project to D2L will result in multiple grades, and we will take the LOWEST one.
  • Include the names of all group members working on the project.

Project regrade requests

If you think that your project was graded incorrectly, you may request a regrade. To request a regrade, please fill out this http://amath.colorado.edu/sites/default/files/2015/10/1292036722/LabReg… request form , and submit it to either of the people running the APPM 2460 course. Any regrade requests that are unjustified or simply a complaint may lead to a lower project score.
