Group
Project:
Students will be assigned to a group project during the 2nd week of the semester. The team projects are conceived to increase the involvement of the students in the learning process and to promote communications. Through group discussions, the team members will help consolidate the learning process, learn to negotiate, and yet make better decisions. Each group will make a professional presentation and submit a written report at the end of the semester.
Academic
Integrity:
[SA8]Academic integrity, as defined by University Faculty Senate Policy 49-20, is the pursuit of scholarly activity free from fraud and deception and is an educational objective of this institution. Academic dishonesty includes, but is not limited to, cheating, plagiarizing, fabricating of information or citations, facilitating acts of academic dishonesty by others, having unauthorized possession of examinations, submitting work of another person or work previously used without informing the instructor, or tampering with the academic work of other students.
(New Senate policies require instructors to notify students in writing about course policies on academic integrity, examinations, and grading. The syllabus must include the course examination policy, basis for grades, and academic integrity policy for the course. Changes to the syllabus shall also be given to the student in writing. Additional information on General Examination Policy (Policy 44-10), Non-final Examination, Evening Examinations (Policy 44-30), Basis for Grades (Policy 47-20), Academic Integrity (Policy 49-20) can be found at http://www.psu.edu/ufs/policies/.)[SA9]
