JUSTIFICATION FOR ACTION REQUESTED
The purpose of the department and campus-wide curriculum committees is to
scrutinize course change and new course applications to make sure that the quality
of UAF education is not lowered as a result of the proposed change. Please address
this in your response. This section needs to be self-explanatory. Use as much
space as needed to fully justify the proposed course.
In an effort to better serve our students and address job market opportunities, the
Drafting Technology program is pursuing several changes to its course and degree
offerings. We are refining our course offerings to focus on producing graduates that are
first, knowledgeable and skilled in CAD, and second, familiar with a specific trade or
discipline.
A Format 5 form has been submitted for changes to the Drafting Technology Certificate
program. A Format 3 form has been submitted for creation of an A.A.S. Degree in
Drafting Technology. Both proposals incorporate this course offering.
Throughout the Drafting Technology program, students receive the majority of their
instruction in computer aided drafting (CAD). However, students receive little to no
exposure to actual mechanical and electrical engineering practices in creating drawings,
the design process, or to the engineering office environment. This course will provide
students with the trade specific vocabulary to communicate with engineers about
mechanical and electrical drawings and the skills to quickly and accurately produce
those drawings. Taken in conjunction with the already offered Construction
Management course CM F142 Mechanical and Electrical Technology, this course is
designed to produce graduates ready to enter the workforce as mechanical and electrical
draftspersons.

Instructional Methods
Lectures:
Guest Lectures:
Collaboration:
Blackboard:
Each class will begin with a short review of the learning objectives
for that day’s class. Material for that class will be covered through
the use of slides, product samples, construction document review,
and demonstrations. Students are encouraged to participate in
the demonstrations and in instructor-led discussions. Students are
expected to have any assigned reading or homework completed
prior to class in order that they can actively participate.
Guest lecturers from the industry may present throughout the
semester.
Design work, and therefore drafting, requires extensive
communication. Drawings, after all, are a form of communication.
Students are expected to interact and learn from one another.
The best CAD tricks or tools are learned from other users, not a text
book or tutorial.
Blackboard will be used extensively. Discussion threads may be set
up for each assignment, for students to pose questions to the
instructor and each other. Assignments will be turned in via
Blackboard. Lectures, announcements, and schedule adjustments
will be posted via Blackboard.
Course Policies
Attendance:
You are expected to attend classes regularly; unexcused
absences may result in a failing grade. You are responsible for
coordinating absences and the possibility of arranging to make up
missed work with the instructor prior to the absence.
 Attendance will count as part of your grade. See Grading
Policy.
 If an unforeseen circumstance prevents you from attending
class you are expected to contact the instructor via email or
phone prior to the start of class.
 If you are required to participate in either (a) military or (b)
UAF-sponsored activities that will cause you to miss class, you
must notify your instructor as soon as possible of your absence.
You must notify your instructor of all scheduled UAF-required
absences for the semester (e.g., travel to athletic events)
during the first week of classes.
Late Assignments:
Late assignments are discouraged, but will be accepted. The
grade for late assignments will be reduced by 10% after the
original due date, and by an additional 10% every week
thereafter.
Missed Exams:
Missed exams will not be available to be made up unless prior
arrangements have been made with the instructor.
Important Dates:
