METHOD OF INSTRUCTION: Methods of instruction include but not limited to traditional
lectures, demonstrations, Labs, web enhancements, Library independent study, on line,
ITV, projects, cooperative teaching, problem based learning (PBL), independent study,
presentations by the students, quizzes, HW, Tests, technical report writing, interactive
teaching etc)
QUIZZES: There will be five or more unannounced pop-quizzes throughout the term, each
quiz counting for 20 points or less. These will typically be at the beginning of class and will
only take a few minutes to complete.
EXAMS: There are three regular exams worth 100 points each, and one final exam
(comprehensive) worth 200 points. You MUST be present for an exam unless cleared with
the instructor beforehand, or unless there is verifiable and extraordinary reason for your
absence. No make up exams are generally given in my classes. If a make up exam is
given for some unavoidable circumstances, it will be different than the exam given to the
rest of the class. All exams are closed book, but in some cases a formula sheet may be
given.
3
HOMEWORK: Homework will be assigned for each chapter. Homework will usually be
assigned each week, and will reinforce the material taught in class and help prepare for
exams. Homework will be evaluated on accuracy, completeness and presentation. Home
works are due at the beginning of the designated class. Late home works will NOT be
accepted.
LAB EXERCISES: There will be eight labs worth 25 points each. Labs will presented
after a short break following the lecture and can take one or two class periods. Lab topics
will be chosen as the course proceeds based on class progression and available
equipment. Labs will be based on the lab manual noted above, so you must have your
own copy of this manual. Labs are an important part of the course, and you should pay
particular attention to them. If time permits, the last two labs may be in the form of a final
project which will be presented to the class at the end of the term.
MAKE-UP LABS: If you miss a lab or need extra time to complete a lab, you may work in
either the Rm.87 or 89 labs on Fridays providing that either an instructor or technician is
present in the area.
Late HW, Make up exams, quizzes, retesting etc: HW has to be turned in on time. No
late HW will be accepted under any circumstances. If a student had an excused absence
he/she will be given equal opportunity to make up assignment(s). No make up assignment
will be allowed for unexcused absences and students will score zeros for all assignments
for unexcused absences. No make up quizzes will be allowed. For excused absences
those quizzes will not count. All others will score zeros on quizzes. No retesting is
permitted for any individual student. But entire class may be retested for various reasons if
instructor so desires.
SAFETY: The lab equipment used is potentially dangerous, and you should at all times
keep safety in mind. There will be a safety lecture given at the beginning of the course,
and you MUST have been given this lecture before you begin to work on any labs.
*** Food and drinks are STRICTLY PROHIBITED in the lab area ***
ATTENDANCE POLICY: Attendance and class participation are key elements for the
course, and attendance (on time!) at every class meeting is expected. Excessive
absences can lead to your administrative withdrawal from the course. A student will be
dropped from class if he/she has more than three absences in one semester. Three
tardies will make up one absence.
WITHDRAWL POLICY: As mentioned above in attendance a student may be withdrawn
from the course due to lack of attendance by the instructor. Poor performance in a class
may also result into withdraw from a course by the instructor. Other withdrawal policies of
NMSU (DACC) stay effective in the class. For that please check appropriate student hand
book or other document of college.
Financial Aid Notice: You must attend classes to receive financial aid. If you stop
attending or drop any course(s) you may be required to repay all or part of financial aid
received.
4
CLASSROOM CONDUCT: You are encouraged to ask questions during the lectures or
lab sections. Drinks (no food!) are OK during the lectures but are NEVER permitted in the
lab areas. Talking during the lectures or other distractive behavior will not be tolerated.
Any persistent unusual/abnormal behavior in the class may lead to a drop out from class
by the instructor.
GRADING:
Grading will be based on a point system as noted below:
900 and higher
800 - 899
700 - 799
600 - 699
599 and below
A
B

F
Points are tallied from a combination of exams, lab exercises, homework, and quizzes as
shown below:
Quizzes (5 x 20)
Homework (8 x 25)
Lab Exercises (8 x 25)
Exams (3 x 100)
Final Exam
100 pts
200 pts
200 pts
300 pts
200 pts
If for some reason the allotted number of labs, quizzes or homeworks are not reached or
are more than mentioned, the weight will be adjusted accordingly. For instance, if only 4
quizzes are given instead of 5, each quiz would then count for 25 points.
EMERGENCY ALERT SYSTEM (EAS): Emergency can be found at
http://safety.nmsu.edu/emergency.htm (for relevant weather or other emergencies)
PROFESSIONAL DEVELOPMENT:
One of the objectives of this course is for each student to be able to display their
positive attitude toward responsibilities and the good work habits that are expected
of successful electronic technicians. Examples of this attitude and these habits are,
but are not limited to:
(1)Attendance and participation in class and lab activities with the appropriate
professional appearance and demeanor are critical to the successful learning of the
course competencies which will be reflected in your final grade.
(2)A sense of responsibility for quality workmanship, safety, ethical behavior,
attendance and punctuality.
5
(3)Self-motivation and initiative, which includes the willingness to spend the extra
time and energy required to learn new concepts and techniques for competence in a
rapidly changing and advancing field.
(4)Cooperative attitude toward fellow workers and supervisors which is
demonstrated through class participation and the ability to work well with others.
The number of professional development points you earn, in part, may be
determined by a short essay in which you describe how you have met the above
expectations during the semester.
ACADEMIC HONESTY: Students should follow the Code of Conduct as noted in the
DABCC Student Handbook. While you are encouraged to share ideas with other students,
all submitted work must be your own. Articles/materials printed form the web pages as is
will be cheating.
EXCUSED ABSENCES: If you know that you cannot attend a class on a certain date for a
valid reason (travel for work, family/medical issues, etc.), contact the instructor at least a
week BEFORE your absence. Arrangements will then be made for you to submit your
work or take a test at an alternative time. Unexcused tests cannot be redone except in
extraordinary circumstances. Excused absence will be considered an absence from class
and will count towards three allowed absences.
EXTRA ASSISTANCE: If you require extra lab time or assistance with your homework,
please see the instructor or lab technician for a special appointment. Students may also go
to get help from “student success center.”
TUTORING AVAILABILITY: Students may get help from “student’s success center.” A
graduate student has been hired to tutor students on Mondays 9-10 am, Tuesday’s 1112:30 noon, and Fridays 3:00 pm to 4:30 pm. There will be tutoring available during Labs
and 30 minutes after Lab time is over by your instructor.
SAFETY: Safety is a concern of all of us. Any unsafe practices should be brought to the
notice of the instructor. No unsafe environment will be tolerated and no compromises will
be made to the safety of the students and the instructor.
AMERICANS WITH
DISABILITIES ACT
DISABLED STUDENT SERVICES: If you have, or believe you have, a disability you may
wish to self-identify. You may do so by providing documentation to the Office of Services
for Students with Disabilities (SSD) located in Room 117 at the DABCC Central Campus in
Las Cruces (Gregg and Espina) (Phone: Voice 527-7548, TTY 527-7647). Appropriate
accommodations may then be provided for you.
If you have a condition which may affect your ability to exit the premises in an emergency
or which may cause an emergency during class, you are encouraged to discuss this in
confidence with the instructor and/or the Specialist, Services for Students with Disabilities.
A brochure, "Self-Disclose, Don't Presuppose" is available in Room 117 at the DABCC
6
Central Campus in Las Cruces (Gregg and Espina). If you have general questions about
the Americans with Disabilities Act (ADA), call the ADA Coordinator at 527-7545 or
646-3635.
EXTRA CREDIT: I reserve the right to give extra points to an assignment or exam when
students have done exceptional work. Credit may also be given for make-up assignments
related to excused absences. Extra credit is not intended as a means to makeup for poor
quality work or unexcused absences. Extra credit assignments will be given to the whole
class and not to one particular student. There will be uniformity for any extra credit for the
entire class. All or none.
DISCLAIMER: The following course schedule is a guideline only. While a strong effort
will be made to follow the schedule, there may be deviations as needed to best meet class
goals.
Tentative Schedule : All HW assignment are due in the next class meeting after the
chapter for the hw is finished/done. No late assignments will be accepted
