See lab instructor for consultation time regarding laboratory exercises, lab content, and lab reports |
Any announcements regarding class assignments, exams, and schedules are made during these times. Students are expected to sign in for their attendance at each lecture in a sign-up sheet placed on the desk by the instructor. Excused absence(s) must accompany third-party verification (letter from an instructor, doctor, etc.). Each unexcused absence after the first three unexcused absences will cost 10 point deduction per absence.
10:00 - 10:50 a.m. M & W (Room 118, Horticulture)

[If an emergency exists and you need to miss a laboratory session, contact your laboratory instructor prior to the laboratory period. There may be the possibility to complete the laboratory class if sufficient notice is provided. Rescheduling is only for emergencies and is up to the discretion of the laboratory instructor.]
Expected goals and objectives for each instructional unit/topic are listed at the beginning of each unit's material for the lecture.

Examination and laboratory make-ups are at the discretion of the instructors if the notice of absence is made PRIOR to the exam. You may e-mail or telephone the instructors, as this information is logged by time and date. A written excuse will be required to allow for a makeup examination, for both lecture and laboratory sessions, from a responsible third party (such as a medical doctor, student health center, advisor, clergy, Dean of Students, etc.).
If you have a disability and require accommodations, please contact the instructor early in the semester so that your learning needs may be appropriately met. You will need to provide documentation of your disability to the Disability Resources (DR) Office, located on the main floor of the Student Services Building, Room 1076, Phone 515-294-6624. The disability resources staff can provide a SAAR (Student Academic Accommodation Request) form verifying your disability and specifying the accommodation you will need.
Student behavior and interactions affect your and other students' learning. Be sure to follow classroom etiquette and civility requests. Be respectful of students' learning needs, such as not talking or using other disruptive actions in class; follow instructions carefully; turn off your cell phone unless of an emergency and then inform the instructor prior to the class period; and use respect and courtesy to others - allowing for an excellent learning environment.
Lecture and lab periods begin on time unless of an unforeseen incident for the instructors. Please arrive to the class on time so as not to disrupt the other students. If you know that you might be late due to a previous class that is located far away on campus, please inform the instructor(s) so that arrangements may be made.
Do not exit out of the emergency exit door in the northwest corner of the lecture hall except in the case of an emergency. Place all of your garbage in the trash cans - remember: "If you can carry it in, you can carry it out"!
