Purpose

The intent of the EF 151 portfolio is to help you organize and document your practice problems in a clear and methodical manner.

Academic Integrity

Turning in a written work for a problem that you have not attempted online, turning in a written work that does not have your parameters, or turning in written work that is copied from someone else is academic dishonesty and will be reported to the Office of Student Conduct & Community Standards. Penalties for academic dishonesty can include zeros on assignments up to and including failure of the course.

Practice Problem Guidelines

• Write out your work and show all of your steps!
• Use engineering paper or the EF 151 PROCESS Template.
• All work should be done in pencil. You may also use a tablet with a pen as long as you are still writing the the problems in your own handwriting and using a digital engineering paper or PROCESS template.
• If a problem has multiple parts, you need to clearly communicate each part.
• You may put multiple parts of the same problem on one sheet if space permits.
• Set up the problem in form of PROCESS.
  • Problem Statement: A concise summary of what you are solving for in the problem.
  • Represent the Problem: Draw a sketch to visualize the problem. As best as possible, draw to scale, and keep it large enough to label.
  • Organize Information: Write known values with variables and any assumptions you are making.
  • Calculations: Show all equations in variable form before plugging in values to calculate intermediate values and your final answer.
    • Write legibly and neatly. If you make a mistake, you may cross it out and move on. No need to erase (especially on exams).
    • Write units on every number, unless it is a dimensionless quantity.
  • Evaluation Solution: You do not need to write anything for this part. If you use the PROCESS template, check the boxes as you go through the checklist. For this part you should, check that your:
    • units are consistent,
    • equations are appropriate for the physical system being evaluated and are written in variable form,
    • answer is reasonable given the magnitude of the values in the problem,
    • final solution answers the problem statement, and
    • final solution is in the correct form (vector or scalar) and has appropriate units.
  • Final Solution: Round your answer to an appropriate number of significant figures, include units, and highlight your answer by placing it in a box or double underlining it.
  • Self-Evaluation: You don't need to write anything for this part, but it is critical for your learning! Think about the problem, where you got stuck, and what you need to review moving forward. Also, note if there are any mistakes you made that you don't want to make again.

You will be required to use this format on exams, we will discuss what that will look like specifically as the first exam gets closer.

Upload Your Work upload a picture of your work for each problem to the online homework system

• If a problem spans multiple pages, you will need to put the pages side-by-side and upload a single picture for the problem.
• If you have multiple problems per page, you still need to upload a picture for each problem.

Example

Grading

Uploads

• The upload portion of your portfolio grade will be based on the timestamps of the images you have uploaded.
• These timestamps are compared to the problem's due dates and credit given accordingly.
• This grade is not automatic - it is updated periodically.
• Intentionally uploading incomplete or inaccurate images will be considered a serious case of academic dishonesty and handled accordingly.
• The upload credit may be adjusted based on a manual review of your uploads

Format

• The format portion of your portfolio grade will be based on a manual review of your uploads to evaluate format and completeness. The grading rubric is given below.

Grade Item	Good	Fair	Poor
PROCESS documentation: Student demonstrates ability to discern key and necessary information and to develop logical strategy.	20 pts Problem statement is succinctly summarized; key information has been identified; a detail problem representation is included; equations have been identified; calculations follow a logical strategy; final answer is clearly identified.	15 pts Problem statement, key information, and problem representation have been communicated, but some is missing, or clearly unimportant information included; flaws calculations.	5 pts Problem statement simply copied or missing; no problem representation; few or no calculations; final answer not indicated.
Calculations: Student demonstrates clear understanding of physics concepts through calculations.	30 pts Problem translated into appropriate mathematical language and equations; all important elements of problem are identified, appropriate diagrams and equations are used.	25 pts Only partial connections between/among concepts. Problem started appropriately but changes to incorrect focus.	10 pts Incorrect procedures without understanding the concepts related to the task.
Organization and Clarity: Student demonstrates ability to organize work in a clear, coherent, and logical manner.	20 pts Details fit and make sense; one step flows to the next and shows organization.	15 pts Parts of solution either missing or difficult to follow.	5 pts Minimal evidence of a solution process; process difficult to identify.
Image Quality & Format: Student demonstrates ability to upload quality images and used approved paper.	10 pts Images are clear and work is on engineering paper or the PROCESS template	5 pts One error (e.g., images are blurry or not on engineering paper / PROCESS template).	0 pts Two or more errors.
Neatness: Student demonstrates ability to write problems neat and legible.	20 pts All work neat and legible; uploaded images are high quality.	15 pts A few parts are sloppy, but readable. This includes a few poorly written equations that could be misinterpreted.	5 pts A few parts are unreadable, and much of homework is sloppy.
