COURSE PROCEDURES
1. MECT 3341 is the third course in the Computer Drafting Design Minor sequence and a junior
level course in the Mechanical Technology major. Programming and engineering drafting
experience are prerequisites for this course. A pretest in computer programming and engineering
drafting will be given to all students during the second-class meeting. The main purpose of this
exam is to alert the instructor about those students who do not have the expected prerequisite
background.
2. Students are expected to be completed all reading assignments outside of class time and is to
be accomplished prior to the lecture class period of the week assigned. Students should be
prepared for a 10-minute pop quiz at the beginning of any class covering the reading material.
3. All exams will be given on Saturday 8:00am room to be announced through in lecture &
WEBCT. If for any reason there are changes to the date, time or the room location, the new date,
time and room location will be posted using WEB-CT.
4. All assignments will be turned using the course WEB CT Web Site. Files are electronically
uploaded into WEB CT. Students will not get credit for an assignment not turned in via WEB
CT. WEB CT will not accept files after the deadline (date and hour) indicated as DATE / TIME
DUE.
5. All Files of any type (.DOC, .DWG, .LSP, etc) turned in to WEB CT will be identified using
a File Naming Convention. The first five letters of the file naming convention are XYZAB
where XYZ are the first three letters of your Last Name and A is the first letter of your First
Name and B is the first letter in your Middle Name. Use an X in place of any letter not in your
name (two-letter first name or no middle name). Follow the five naming convention letters with
an explanation of the assignment. Example: parrclab01 for Ronald C. Paré, lab 1. Add
sequence letters (A, B, etc.) if more than one file is being submitted for an assignment.
Example: parrclab03A and parrclab03B.

6. Written Reports ( 3 are required ) the due date are posted on WEB-CT which is usually
Saturday at 11:59pm of the week due. Submit a hard copy to your LAB TA’s and digital copy to
WEB-CT. No late reports will be accepted.
7. All in class and homework assignments will be graded on a 10 - point maximum basis except
for Assignment 3 which will be graded on a 20 – point maximum. Regular exams will have a
100-point maximum; the final exam will also have a 100-point maximum. The Group Project
will be graded on a 270-point scale. Assignment grades will be based on the following:
a. Correctness of the assignment: 80 %
b. Presentation: 20 %
8. Laboratory assignments are an important part of this course.
a. All assignment ( 13 assignments) are due Saturday 11:59pm (one weeks after the laboratory
class for which it was assigned). See the WEB-CT for Due-Dates.
b. Programming assignments ( 3 ) are to consist of a flowchart, program listing and plotter
output.
c. Computer graphics assignments ( 10 ) are to consist of plotter or printer/plotter output as
indicated by the assignment instructions or by the instructor.
d. Students are expected to complete these assignments on time and will be required to do so to
earn a high grade for the course.
e. Most laboratory assignments can be completed during the 3 hours of scheduled laboratory
periods of the week(s) assigned.
9. Students need to become familiar and comfortable working in a group/team as will be typical
when employed after gradation. A Group Design Project (to be completed outside of lab and
class time) will provide experience working on a team. Each student in the group will selfevaluate the project results and team participation. Self-evaluations and instructor evaluation
will be averaged to determine each individual student project grade. This project is a significant
portion of the course grade and will have to be completed to earn a high grade in the course.
10. Except in the case of an excused absence (when the instructor is notified in advance of the
absence) will an assignment be accepted for a grade subsequent to two class periods after the
due date / time. When assignments are turned in late, there will be a one (1) - point deduction
for first day late, a three (3) - point deduction for ever day after the first late date.
11. All assignments must be turned for a graded, even if that assignment is turned in after
the date for earning a grade has passed.
12. All class exams and quizzes are closed book.
13. No make-up exams. For one missed exam (with an excused absence) a score of 85 percent
of the average class score will be assigned. For two missed exams, a zero (0) will be assigned on
both exams. For excused absents refer to item 14 section b below.

14. The University “Attendance” and “Dropping A Course” Policies are published in the
Student Handbook. For this course, Attendance, absences and satisfactory progress standards
are:
a. Students are expected to attend every lecture class. Attendance and or viewing
lectures will be verified using unannounced pop quizzes and/or a Secret
Word/Question. Students will receive Participation Credit (5 % of the total course
grade) by notifying the instructor of the lecture Secret Word/Question, answers are
due before each exam. The student will e-mail them to the instructor; remember to
put your name on the list of secret words. The instructor will not drop any student
from this course. It is the student’s responsibility to drop themselves from the course.
b. An excused absence (especially on exam days) requires PRIOR notification
(phone or email is OK). Without prior notification the student will receive a 0 for the
exam grade.
c. Students who do not show satisfactory progress by maintaining an average of 60%
on exams and assignments may be dropped any time.
d. If a student drops or is dropped without making satisfactory progress, the
instructor will assign a grade. The grade will be determined at the prorated
percentages shown and will be based on the work due up to the date of the drop.
15. Reading of professional journals and conducting patent and drafting standard searches to
become aware of recent developments in a subject area is an important aspect of learning that
subject. Being able to write effective reports is important for any college gradate. Two written
reports will meet these goals and enhance this course.
16. Involvement in extracurricular activities supported by UH and related to a student major will
also enhance learning. Membership in at least one professional society and participation in
related activities will be expected of students and will have a minor impact on the final grade
earned in this course.
17. Special accommodation. If a student with a learning disability expects special
accommodation, that student must provide the instructor with written certification of that
disability (by the University Counseling and Testing office) before the first exam.
http://www.uh.edu/provost/stu/stu_syllabsuppl.html
18. Academic Honesty. The University Academic Honesty Policy is published in the Class
Schedule and in the University of Houston Student Handbook. This Handbook is free and
students are expected to be familiar with the policy. For this course, cheating is defined as:
Submitting for a grade something that is not your own work or knowingly assisting a
classmate by letting them use your work is also cheating according to the above statement.

Cheating will result in an "F" grade being assigned in this course and may result in additional
action by the University. Steps to discourage cheating will be taken by the instructor in this
course. A picture ID may be required to be provided at each exam.
19. The Engineering Technology Degree Programs at the University of Houston will be
receiving an Accreditation Review by TAC/ABET. All student work (homework, lab work and
exams) and its evaluations will be available for inspection by the Review Team. Students can
also expect that a member of the evaluation team will visit both a lecture and lab session during
this review.
20. The American Society of Mechanical Engineers is committed to helping colleges guide the
development of students and teaches the principles of engineering practice and professionalism
without overburdening an already full undergraduate curriculum. The ASME Professional
Practice Curriculum (PPC) modules cover a diverse array of topics, many pertaining to the
ABET a-k criteria, and they are designed to be suitable for student assignments in engineering or
engineering technology courses as well as for individual study. The module resources include
downloadable presentations for introducing classroom discussion of the modules.
Computer Aided Drafting I students will earn one bonus Lecture Attendance Credit for each
Professional Practice On-Line Module completed. There are currently thirty - (30) modules
available. Therefore completion of a majority of these modules will improve an assignment
grade only. These modules must be completed before the end of the evaluation period at the end
of the semester
