Disability Statement

Any student who, because of a disabling condition, may require some special arrangements in order to meet course requirements should contact disAbility Services (Student Service Center room 119, phone 371-5436) as soon as possible.

Statement for Mental Health and Advocacy & Resource Center:

As a student you may experience a range of issues that can cause barriers to learning, such as strained relationships, increased anxiety, alcohol/drug problems, feeling down, difficulty concentrating and/or lack of motivation. These mental health concerns or stressful events may lead to diminished academic performance or reduce a student's ability to participate in daily activities. Amarillo College offers services to assist you with addressing these and other concerns you may be experiencing. If you or someone you know are suffering from any of the aforementioned conditions, you can learn more about the broad range of confidential mental health services available on campus by calling the AC Counseling Center at 806-371-5900. The AC Counseling Center website is https://www.actx.edu/counseling/ . Also, if you are in need of social services (affordable housing, utilities, transportation, food, clothing, childcare, medical/dental/vision, legal), please call the AC Advocacy & Resource Center at 806-371-5439.

Students Rights and Responsibilities

Log in using the AC Connect Portal

In order to receive your AC Connect Email, you must log in through AC Connect at https://acconnect.actx.edu .

If you are an active staff or faculty member according to Human Resources, use "Exchange". All other students, use "AC Connect (Google) Email".

Expected Student Behavior

Students are expected to behave in the classroom in a manner that is supportive of the learning environment. Behaviors that are not supportive include, but are not limited to: tardiness/leaving early; electronic device noises; texting or using electronic devices for non-course related activities during the lecture; talking during the lecture; abusive, offensive, and/or disrespectful language or demeanor toward AC faculty, staff, students, and/or Amarillo College property.

In order to receive credit for a course, all material listed on the syllabus must be covered. The instructor sets the pace to ensure that these requirements are met. Complaining about  the pace will not result in less material being covered.

Students who fail to comply with the standards outlined in the syllabus and/or AC’s Student Rights & Responsibilities document will be subject to disciplinary action which may include, but is not limited to: removal from the classroom; consultation with the Math & Engineering Department Chair and/or other AC authority; withdrawal from the course and/or Amarillo College.

Grading Criteria

The final grades of A (90-100), B (80-89), C (70-79), D (60-69), and F (below 60) will be computed as the average of the earned grades as follows:

Absence from an exam will incur a zero unless there is prior notification of the instructor with approval granted or there is an emergency that could not be circumvented. Students who miss an exam because of College or business related activities should notify the instructor before the absence occurs.  Make-up exams will be given only under rare, extenuating circumstances and at the discretion of the instructor (after written petition for consideration).

The project counts the same as a major exam.  It will be completed as a group project and includes a written report.

As an engineer, you will need to continue lifelong learning throughout your career.  You will attend workshops, tour work sites, interview clients, among other duties.  To support the goal of lifelong learning outside of the classroom, the Engineering Department will arrange for guest speakers and tours to broaden your education.  There will be speakers on the first Wednesday, at noon, of each month (February, March, and April) and two tours.  You must attend 4 of the 6 actitives and fill out a short report form.  If you cannot attend the activity, you will submit a 3 page, double spaced, 12 point paper (including footnotes) on the topic you missed.  The due date for the paper will be 1 week after the missed activity.  You must notify me one week before each scheduled activity as to whether or not you will be able to attend.

Homework shall be presented on engineering (quadrille) paper, in pencil, one side only. If an error is made, erase thoroughly.  Homework with scratched out work will NOT  be accepted.  Each problem should be started on a new page.  Homework presentations shall be as follows:

• Restate the problem at the top of the page.
• Explicitly state any assumptions that you make.
• Show all significant steps.  It should be clear why each step is taken.
• Redraw figures and clearly label as needed with dimensions, labels, and units.
• Underline important intermediate results.
• Box (not circle) final results.
• Review work to be certain all work is neat* and easy to read.

*NOTE:If I can’t read it, I won’t grade it.

Homework sets shall be stapled upper left and then folded in half along a line perpendicular to the long dimension. The student’s name, course and section number (ENGR 2302-001), date, and the problems included  shall be placed on the outside sheet with the fold to the left, the holes toward the bottom.

Grades will be awarded based on the following formula:

HW mark = (presentation factor) x (correctness)

Here the presentation factor is a number between 0 and 1. This means that homework should be both correct (or mostly correct) and well presented to receive a high mark.  Be advised that if the quality of presentation is very poor, then the submission may not be marked for correctness. But don't get out your word processor. Neat and legible handwriting, preferably printing, and adherence to the above guidelines is all that is required.

Solutions to assigned problems will be posted soon after the problems are due to be handed in.

• The Instructor reserves the right to grade any number of problem(s) per assignment.
• Collaboration between students is allowed on problem solving; however, EACH STUDENT must hand in an ORIGINAL, COMPLETE, problem set.
• NO CREDIT will be given for late homework. Under very rare and exceptional circumstance, as stated earlier, you may submit a written request for consideration of the acceptance of your homework if it is late.

Grading of Tests: In complex problem analyses, such as those used in this course, there are many opportunities for errors. Thus exams will be graded using "partial credit" as it is recognized that  some sections of an individual problem may have been carried out correctly even though the final answer may be incorrect.  Partial credit will only be given if the student work is logically developed, with clear and well marked diagrams, with the appropriate fundamental and auxiliary equations prominently displayed, where the substitutions into the equations are quite clear, and the assumptions used are quite obvious to the grader when grading. That is, it is the student's responsibility to present his/her work so clearly that the grader can quickly ascertain the location and nature of the error(s) and can easily follow the subsequent work through to the now incorrect solution of the problem. Thus, the student's contribution, needed to obtain partial credit, is to be able to clearly lead the grader through the student's thought process on the exam page alone. If this is not quite clear on the work submitted, credit will not be given then nor later. Partial credit is simply not negotiable.

Attendance

You must attend to be allowed the opportunity to take the pop tests and hear the lectures and homework assignments as described below.

Expect to have homework assigned each day.  Please note the homework format requirements.   You  are responsible for the requirements. A number of in-class quizzes may be given during lecture periods. These will count as extra homework. Homework and in-class exam grades will comprise 20 % of the course grade.

Please remember the deadline for dropping a class at Amarillo College during the Spring semester is April 19. If you stop attending class and do not officially drop the course by this deadline, and your average is below a 60, you will receive an F for the course.

Attendance is essential for successful completion of this course.  In order to promote consistent attendance, homework is regularly assigned and in-class quizzes may periodically be given.  Late homework is not accepted and in-class quizzes may not be made up.  Homework may be submitted and exams taken in advance when absences are due to a scheduled event.
