Blackboard will be used to post critical course information – please use Blackboard!

Blackboard website: http://courseware.ku.edu/ Solutions to homework problems will be posted on Blackboard approximately three working days after the due date.

 

 

Course Objectives: The primary course objectives are to enable students to acquire an understanding of basic concepts of materials in terms of their structure, material characterization, and selection criteria for application in design. In ME 346, an additional objective is to provide the students with an opportunity to acquire the basic manufacturing skills and knowledge required for successful completion of their senior design project.

 

Course Policies and Procedures:

1) Academic Dishonesty

Academic dishonesty (cheating) will not be tolerated in the School of Engineering. In this course, cheating will be defined as sharing information during Examinations or Quizzes, direct copying of homework assignments or laboratory reports, allowing others to do the majority of the work for your projects, and plagiarism on the laboratory reports, homework assignments or projects. In this course it is okay to ask each other questions on the homework assignments (but not on Take-Home Exams). This implies that each student has individual active input on every problem or assignment. Tag teams efforts on homework assignments are not allowed and submission of identical homework is not permitted. Use of homework solution manuals obtained by unethical or illegal methods is prohibited. Cheating in class is inconsistent with professional engineering ethics and is a serious violation. If any student is found cheating, he/she will be dealt with in a forthright and no nonsense manner. The instance will be reported with documentation to the Associate Dean and appropriate penalties will be invoked.

 

2) Homework

Completed assignments should be turned in by the beginning of class on the due date in class. Unless the assignment specified otherwise, you must work in teams of three, handing in one team solution per assignment. Each team member should set up each problem individually (read in advance, define the unknowns, outline the solution procedure), then get together to work out the details. On some assignments, this procedure will be required and your instructor will ask for the individual outlines to be signed and turned in.

 

3) Team roles

On each group assignment, your team should designate

-      a coordinator to organize work sessions, make sure everyone knows where and when to meet, and understands who is supposed to be doing what.

-      a recorder to prepare and turn in the final solution set and

-      a checker to check the solutions for correctness and verify that everyone in the group understands both the solutions and the strategies used to obtain them.

The team roles must rotate on every assignment – once a team member has carried out a role, he/she may not do it again until everyone else on the team has done it.

 

4) Homework format

Use engineering paper, one side of each page. Any computer generated work can be printed on regular white paper. Each problem should either be on a new page, or clearly marked between problems. Each completed assignment should be in one person's handwriting (the recorder's). Staple the pages and fold them vertically when you hand them in, putting the names and roles (coordinator, recorder, checker) of the participating group members, the group numer, the problem set number, and date on the outside. If a student's name appears on a solution set, it certifies that he/she participated in solving the problems.

If appropriate, to present the problem solution, start with restating (preferably in your own words) what was given in the problem, what you are to find, and then provide your solution as such:

Given:

Find:

Solution:

The final answer to the problem (if numerical) should be encompassed by a line box. Some problems (such as short answer essay questions) will not require this format.

An example of one properly presented homework problem is posted on Blackboard.

 

5) Late Homework

Homework is considered late if turned in after the end of the class period on the day due. Late homework will be accepted, but penalties will also be imposed as follows:

One (1) day late: 50% deduction from total score.

Two (2) days late: 75% deduction from total score.

Three (3) or more days late: 100% deduction (no credit).

Special exceptions to the late homework policy will be announced in lecture in the case of homework due the class period before an examination.

 

6) Posted Solutions

Homework problem set solutions will be posted on Blackboard approximately 3 days after the due date. Special exceptions will be made immediately before examinations. Homework solutions will be removed from the Blackboard website just before exams.

 

7) Individual effort assessments for team homework

All students will periodically be asked to submit evaluations of how well they and their teammates performed as team members. These evaluations will be incorporated into the assignment of the final individual homework score. If repeated efforts to improve team functioning (including faculty intervention) fail, a non-participant may be fired by unanimous consent of the rest of the team, and a team member doing essentially all the work may quit. Individuals who quit or are fired must find a team of unanimously willing to accept them; otherwise they will receive zeros for the remainder of the homework.

 

8) Tests

There will be two midterm exams and a comprehensive final exam. The point layout of these exams is given on the following page.

9) Missed tests

If you miss a midterm test without either a sufficient and certified medical excuse or prior instructor approval, you will not be allowed to take a makeup test. The percent score on the final exam will be used for your midterm score. Only one midterm exam can be missed. If both midterms are missed, you cannot pass the course. If you miss the final exam without a valid excuse, a zero will be averaged into your grade. Special exceptions may be made on a case-by-case basis. For your benefit, it is strongly recommended that you do not utilize this policy.

10) Review sessions

Your GTAs will hold extra review sessions for your benefit. Attendance at these review sessions is optional. In these review sessions, your GTA will answer questions, illustrate additional example problems, and answer your questions regarding previous homework solutions. Your GTA will NOT work out homework problems for you that have not yet been turned in. Please note that the GTA will not stay more than 10 minutes past the scheduled review session time if no one is present.

11) Disability Services

The staff of Services for Students with Disabilities (SSD), 135 Strong, 785-864-2620 (v/tty), coordinates accommodations and services for KU courses. If you have a disability for which you may request accommodation in KU classes and have not contacted them, please do as soon as possible. Please also see me privately in regard to this course.

12) Calculation of Course Grade

KU Grading System (adapted from the University Senate Rules and Regulations "Article II, Section 2: The Grading System", http://www.ku.edu/~unigov/usrr.html#art2sect2)

 

 

The letters A, B, C, D shall be used to indicate passing work.

-      The grade of A will be reported for achievement of outstanding quality.

-      The grade of B will be reported for achievement of high quality.

-      The grade of C will be reported for achievement of acceptable quality.

-      The grade of D will be reported for achievement that is minimally passing, but at less than acceptable quality.

The letter F shall indicate that the quality of work was such that, to obtain credit, the student must repeat the regular work of the course, or that the student's work was not of passing quality at the time of disenrollment from the course.

 

In general, reported earned grades will follow these guidelines:

-      Outstanding quality ( A ) equates to 90 – 100% of the total available points.

-      High quality ( B) equates to 80 – 90% of the total available points.

-      Acceptable quality ( C ) equates to 70 – 80% of the total available points.

-      Minimally passing quality ( D ) equates to 60 – 70% of the total available points.

-      Not passing quality ( F ) equates to less than 60% of the total available points.

 

Notice 1: I do not curve grades in this course. It is theoretically possible for everyone in the class to get an A (or an F). Your performance depends only on how you do, not on how everyone else in the class does. It is therefore in your best interest to help your classmates in every legal and ethical way possible.

 

Breakdown of total points available:

ME 346 (4 credit hours)

ME 306 (3 credit hours)

Midterm Exam II: 140 points (28%)

Final Exam: 160 points (32%)

Homework: 100 points (20%)

Total: 500 points

 

 

Notice 2: ME 346 students will not be given a passing grade for the four credit hour course unless they earn at least a passing score in the lecture portion of the course.

 

 

13) Gray areas between guaranteed letter grades

A "gray area" of several points below the specified numerical cutoff grades (within a minus certain percent score system) will be used. Using this system, two people getting the same weighted average grade (say, 89%) might therefore get different course grades (A or B). If you are in one of these gray areas, whether you get the higher or lower grade depends on whether your test performance has been improving (your percent score goes up) or declining (it goes down), and whether you participation in group work has been good (up) or inadequate (down).

 

 

14) Consulting with faculty
