1 ECET110 Electronics Circuits and Devices I with Lab Term Information: 2009 Spring Credit Hours 4 Contact Hours: 5 Instructor Information: Name: Pui-chor Wong Telephone contact numbers: Office Hours: address: dress: Posted on ecollege pcwong@devry.edu Class Schedule: DAY TIME ROOM Course Description: This course, the first course of a three-course sequence, introduces concepts of electrical and electronic circuit analysis and design. The sequence integrates the study of both passive electrical circuits (resistors, capacitors, and inductors) with the study of active electronic circuits (diodes, transistors and analog integrated circuits such as operational amplifiers). Practical experience with passive and active electronic components, their design, integration, testing, and troubleshooting in practical circuits of moderate complexity is gained through hands-on labs that complement the course lectures. 1 ECET-110

7 CLASSROOM POLICIES Attendance Attendance is required for all classes. Material will be presented in lecture and may contain material that is not included in the textbook. Consideration will be given for extenuating circumstances, but students should be aware that such circumstances are rare and documentation may be required. The attendance policy stated in the DeVry catalog will be followed. It is the student s responsibility to contact the Attendance Office in the event that notification is required. NOTE: Students who find it necessary to miss class are responsible for all subject matter covered in their absence. Classroom Etiquette As a matter of common courtesy to fellow students and to the instructor, students are expected to be in their seats and ready to take instruction promptly at the beginning of class. Late arrivals and/or early departures can be recorded as absences. 1) All pagers and Cell Phones are to be set so as not to disturb class. 2) Snacks are permissible, except in rooms where they are specifically prohibited. 3) Only one person at a time should be speaking whether it is the instructor or another student. 4) Children are NOT permitted in the classroom or in the lab. Please see the Student Handbook for further information Course Enrollment Each student must be listed on the class roster to receive credit for the course. Grades will not be recorded unless the student s name appears on the class roster. Cheating and Plagiarism Cheating on examinations and other assignments will NOT be tolerated. This includes the utilization of plagiarism; use of someone else s work without properly documenting the source. The minimum penalty is a zero for the assignment. The incident may be documented as an academic integrity issue that will be reflected in the student s permanent record. The student handbook describes other penalties and/or disciplinary actions that may be taken. Do Your Own Work Please take heed of the following statements; failure to do so can drastically affect your grade. It is perfectly OK to bounce ideas off your peers and to get help from peers, however you need to take that information and transform it into your own words and 7 ECET-110

8 work. Program coding is like handwriting; no two people write the same and no two people code the same. If two labs (or more) containing the same code or code of too similar a nature are encountered, students will be asked why, and the work will be subject to an automatic zero. If the situation persists then those involved could be subject to disciplinary action per the school s academic integrity policy in effect, which could lead to those involved being expelled from school. It is important that you understand the programs and processes you are creating. Keep in mind that the advice received from peers may or may not be correct but each student will be required to apply and demonstrate the concepts learned in class. Documentation It is the responsibility of the student to keep, as a record, all returned papers as proof that any required work was submitted for grading, and to provide this proof anytime there is a question about the accuracy of any grading records. It is also the responsibility of the student to retrieve any submitted assignments; the instructor will attempt to return assignments only one time. Additional Assistance Students are encouraged to seek help during regularly scheduled office hours or by appointment. Please contact the Academic Receptionist to schedule an appointment and gain admittance to the faculty office areas. If you feel you are in need of additional assistance, please contact the Student Resource Center. The SRC provides tutoring to students at no charge but students should schedule appointments in order to confirm that staff is available when needed. Complaints Any complaints about this course should first be brought to the instructor. If satisfaction is not received there, the complaint may be presented to the Academic Program Dean in writing. If the complaint is not resolved, the escalation procedure should include the Dean of Academic Affairs, and the President. Each student is respectfully requested to adhere to the appropriate chain of command. Course Withdrawal Procedures The last day to withdraw from standard delivery classes is the Friday of Week 11. All signed forms must be submitted to the Registrar s office by noon on that Friday. The last day to withdraw from an accelerated course is the Friday before the scheduled Final Exam. Please refer to the Academic Calendar for the actual date, as dates may vary with each trimester. Course Withdrawal Forms may be obtained from the Academic Office. A 8 ECET-110

9 withdrawal from the class prior to the deadline will result in the student receiving a grade of W for the course. Other Students are encouraged to notify the instructor of any issue not addressed in this syllabus or in official DeVry literature that is important to them. Appropriate information about such issues will be given to the students at the instructor s earliest opportunity. All students are strongly encouraged to make the most of the educational opportunities DeVry offers and to be professional and aggressive in their pursuit of knowledge. 9 ECET-110
