Final Exam (As scheduled)

Ch 5 – 9

 

 


 

Course Activities:

Journals:  Keep a notebook with reading notes and homework solutions (see above).  Journals will be collected randomly 5 – 10 times throughout the term.  They will be graded on completeness.   You should take brief notes on each reading assignment.  Focus on questions that you have from the reading.  Also solve the assigned daily problems.  Problems will be graded as Credit/No Credit.  These are to be submitted individually.  Assignments must be neat and solutions easy to follow for full credit.  Solutions will be posted outside the instructor’s office.  We will discuss the problems in class and students may correct and complete their work in an alternately colored pen.  Journal grading is 66% problems and 33% reading notes.

 

 

 

Homework problems:  There will be 1 – 3 graded problems each chapter.  These problems are to be done individually – do not discuss these problems with each other.

 

 

 

Labs:  There will be three group projects or labs.  Each project will require a brief presentation and a technical report.  These will count as two HW sets each.

 

 

 

Exams: There will be two exams for this course.  If a student cannot take an exam at the scheduled time a request must be made in writing for an alternate at least one week prior to the exam time.  Exceptions will be granted at the discretion of the instructor.

 

 

 

Final Exam:  The comprehensive final exam will be given as scheduled by the registrar.  If a student cannot take the final exam at the scheduled time a request must be made in writing for an alternate at least one week prior to the exam time.  Exceptions will be granted at the discretion of the instructor.

Final Grades will not be “curved.”

 

 

Ethics:

Students are to act in accordance with the Pledge of Integrity as stated in the student handbook on all course assignments.  They will be asked to reaffirm their commitment to the pledge with their signature on each exam.  Dishonest practice can result in failure of the course and possibly expulsion from the college. 

 

 

 

All work should represent each student’s individual efforts, with the exception of group assignments, which should reflect the combined efforts of all members of the group.  Students are strongly encouraged to study together and learn from each other.  They may discuss homework solution techniques with other students and/or the instructor, students should only discuss Hand In problems with the instructor.

 

 

 

Exams are to be taken without discussion, except for problem clarification from the instructor. 

 

 

 

Any solution obtained from any source should be properly referenced.

 

 

Re-Grading:

Written requests, with full rational, for re-grading of all course-work will be accepted the next class period after original materials are returned to the students.
