COURSE REQUIREMENTS:

Students are responsible for attaining competencies through completion of the following course requirements:

ATTENDANCE:

Students should adhere to the attendance policy set forth in the York Technical College Student Handbook. Student must attend 80% of the hours assigned the class for a semester to receive credit for the course. In case a student does miss a class, he/she is responsible for obtaining the material that was covered during the absence. If a student is aware that he/she will miss a class, then the student should notify the instructor at the earliest possible date. If a student misses a test because of illness or urgent emergency, it is the responsibility of the student to do the following:

Notify the instructor prior to the scheduled test date or at the earliest possible date. Make an arrangement with the instructor to make up the test. (Students with unexcused absences at the time of the test will be allowed to take a make-up test only at the discretion of the instructor.)

ACADEMIC HONESTY:

York technical college adheres to the South Carolina Tech student code, approved by the State Board for Technical and Comprehensive Education on March 13, 1974 and again on April 25, 1984). Copies of this codeare available in the Library and from Student Services. Any student caught cheating, or involved in any other academic dishonesty, will be given a grade of zero and will be subject to further disciplinary action.

PARTICIPATION IN CLASS DISCUSSIONS, PROBLEM-SOLVING; COMPLETING ASSIGNED HOMEWORK, LAB EXPERIMENTS AND REPORTS, COMPUTER PROGRAMS AND SIMULATIONS, AND WRITTEN TESTS.

LABORATORY REQUIREMENTS:

Laboratory experiment worksheets will be handed out each week, completed by the student, and submitted by the next laboratory period. All data taken during the experiment and observations noted by the student will be part of the laboratory report. Any questions will be answered and a hard copy of all computer simulations will be attached to the laboratory report prior to submission.

EVALUATION STRATEGIES/GRADING:

The following scale will be the standard:

Grade Score

    A          90 - 100
    B         80 - 89
    C         70 - 79
    D         60 - 69
    F         below 60

Final grades will be determined as follows:

Each module will have equal weight and contribute 25% toward the final grade.

Grades for each module will be determined as follows:

    Major Tests   (minimum of 1)               50 %
    Laboratory     (minimum of 1)              25 %
    Instructor Options      15 %
    Affective Skills            10 %

    1. Attendance at 95% or more of the classes and labs.
    2. Dependability (No tardiness).
    3. Acceptable student conduct as defined in the College Catalog.

The instructor options will be discussed with the students during the first week of class. These options may include homework, spot quizzes or written reports.

Students are expected to "conduct themselves with dignity and to maintain high standards of responsible citizenship." (York Technical College Catalog, Student Life Section. "Student Conduct"). Points will be deducted for disruptive behavior that violates the principles of acceptable conduct.

ENTRY-LEVEL SKILLS:

The student must be able to build and test a basic electronic circuit starting with a schematic diagram.

METHOD OF INSTRUCTION:

This course consists of 3 hours of class periods and 3 hours of laboratory time each week. The class instruction includes lectures, discussions, problem-solving sessions, and tests. The lectures are administered using the chalkboard, overhead transparencies, and video tapes. The discussions consist of student-student and student-instructor dialogue. The problem-solving sessions consist of students working problems on the chalkboard or at their desks while the instructor checks their work. The laboratory experiments follow and complement the class lectures. The students are given instructions before the laboratory begins so they can perform the experiment.
