Course Materials

There is no required textbook for this course. 


The five practicum exercises are 40% of your grade. They are worth 80 points each, totaling 400 points.

  • Practicums consist of essay questions that focus on situations or problems relevant to materials that are being studied.
  • While each individual will be assigned questions to complete, the teams share responsibility for satisfactory completion of the entire set of practicum questions.
  • Individual grades for each practicum exercise are determined as follows:
    • 10 points for your initial posting of answers to your team's message board.
      Criteria: Timeliness and completeness. Practicum answers will be submitted via the course tools provided in the course pages.
    • 20 points for posting at least two original questions to each of your teammates, based on the answers they provided to their assigned questions. (Questions may be of several types: challenge questions, in which you take issue with something contained in an answer; clarification questions, in which you request a clearer statement in an answer; and elaboration questions, in which you request additional information in an answer.)
      Criteria: Insight, responsiveness, and constructive criticism.
    • 20 points for adequately responding to the questions posed by your teammates (and, in some cases, the instructor).
      Criteria: Quality, comprehensiveness, and accuracy.
    • 30 points for your final posting of answers to your team's message board.
      Criteria: Timeliness and completeness, quality, comprehensiveness, and accuracy. Practicum answers will be submitted via the course tools provided in the course pages.


There are 13 quizzes within the course worth a total of 200 points. You have the opportunity to take each quiz 5 times. Practice! In computing your final grade for the course, the quizzes are worth 20% of the grade that you can earn for this course. The questions are just like those you will find on the exams.


There are two one-hour exams and a comprehensive two-hour final exam. Together, all three of these exams make up 40% of your grade. Each one-hour exam is worth 100 points each and the final exam is worth 200 points. All exams are online and multiple choice.


A webcam or a headset with a microphone is required for this course.

Academic Integrity

Academic integrity is the pursuit of scholarly activity in an open, honest, and responsible manner. Academic integrity is a basic guiding principle for all academic activity at The Pennsylvania State University, and all members of the University community are expected to act in accordance with this principle. Consistent with this expectation, students should act with personal integrity, respect other students' dignity, rights, and property, and help create and maintain an environment in which all can succeed through the fruits of their efforts. Academic integrity includes a commitment not to engage in or tolerate acts of falsification, misrepresentation, or deception. Such acts of dishonesty violate the fundamental ethical principles of the University community and compromise the worth of work completed by others (see Faculty Senate Policy 49-20, G-9 Procedures, and the Code of Conduct).

Please read the academic integrity guidelines for the College of Agricultural Sciences.

A lack of knowledge or understanding of the University's academic integrity policy and the types of actions it prohibits and/or requires does not excuse one from complying with the policy. Penn State and the College of Agricultural Sciences take violations of academic integrity very seriously. Faculty, alumni, staff, and fellow students expect each student to uphold the University's standards of academic integrity both inside and outside of the classroom.

Educational Equity Statement

Penn State takes great pride in fostering a diverse and inclusive environment for students, faculty, and staff. Acts of intolerance, discrimination, or harassment due to age, ancestry, color, disability, gender, gender identity, national origin, race, religious belief, sexual orientation, or veteran status are not tolerated and can be reported through Educational Equity on the Bias Response page.

Privacy Policies

For information about Penn State's privacy statement and what it encompasses, please read their Web Privacy Statement. Visit Penn State's FERPA Guidelines for Faculty and Staff page for information regarding its rules governing the privacy of student educational records.

Copyright Notice

All course materials students receive or to which students have online access are protected by copyright laws. Students may use course materials and make copies for their own use as needed, but unauthorized distribution and/or uploading of materials without the instructor's express permission is strictly prohibited. University Policy AD40, Recording of Classroom Activities and Note-Taking Services, addresses this issue. Students who engage in the unauthorized distribution of copyrighted materials may be held in violation of the University's Code of Conduct, and/or liable under federal and state laws.

Counseling and Psychological Services (CAPS)

Many students at Penn State face personal challenges or have psychological needs that may interfere with their academic progress, social development, or emotional well-being. The University offers a variety of confidential services to help you through difficult times, including individual and group counseling, crisis intervention, consultations, online chats, and mental health screenings. These services are provided by staff who welcome all students and embrace a philosophy respectful of clients' cultural and religious backgrounds, and sensitive to differences in race, ability, gender identity, and sexual orientation.

Accommodations for Persons With Disabilities

Penn State welcomes students with disabilities into the University's educational programs. Every Penn State campus has an office for students with disabilities. The Student Disability Resources website provides contact information for every Penn State campus. For further information, please visit the Student Disability Resources page.

In order to receive consideration for reasonable accommodations, you must contact the appropriate disability services office at the campus where you are officially enrolled, participate in an intake interview, and provide documentation. If the documentation supports your request for reasonable accommodations, your campus' disability services office will provide you with an accommodation letter. Please share this letter with your instructors and discuss the accommodations with them as early in your courses as possible. You must follow this process for every semester that you request accommodations.

Accommodations for Military Personnel

Veterans and currently serving military personnel and/or spouses with unique circumstances (e.g., upcoming deployments, drill/duty requirements, disabilities, VA appointments, etc.) are welcome and encouraged to communicate these, in advance if possible, to the instructor in the case that special arrangements need to be made.

Use of Trade Names

Where trade names are used, no discrimination is intended and no endorsement by World Campus, Outreach and Cooperative Extension, the College of Agricultural Sciences, or The Pennsylvania State University is implied.
