Course Activities

Lectures: 75 minutes is reserved for lecture every day. The instructor will write the lecture material on the whiteboard, and you must take copious notes. This course has no required textbook, and my lecture notes will not be made available to you in any form. Requests to make audio recordings of lectures may be granted; no still or video photography is allowed. Exam material will be based on what is covered in the lecture and laboratory. Occasional handouts pertaining to lecture material will be provided. At the end of most lectures, a PowerPoint presentation will show photographs and other information pertinent to the lecture presented. These PowerPoint files – which are NOT comprehensive of the lecture material and NOT a substitute for lecture notes – will be posted via Canvas at some point after the presentation.

Why so little PowerPoint? Unfortunately, to learn mycology you need to learn a lot of terms and life cycles – there is no way to avoid it. Note-taking is a key part of the learning process for students, and my writing material on the board keeps the pace of the lecture manageable.

You will need to use a pen/pencil and paper to take notes; I strongly recommend using loose-leaf notebook paper that can be placed into a three-ring binder along with course handouts. A laptop or tablet will only work for the text portions of the lecture material - diagrams and illustrations comprise a large portion of the material covered. In reproducing diagrams, you do not have to be a good artist, but you should be able to provide a schematic that answers the question.

Students who do best in the course not only take good notes, they curate them into a personal study guide.

Laboratories: After a ten- to fifteen-minute break following lecture, 2 hours and 30 minutes are reserved for the laboratory period. The prepared laboratory activities should not take that long, and the remaining time is available for you to work on projects and lab reports. No one will dismiss you from laboratory – you are free to leave when you have completed your work for the day. However, I recommend that you not run off as soon as you can: wisely utilize this time in your schedule.

Field Trips: We will take three to five field trips to local forests to collect fungi, depending on conditions. If fungal fruiting is poor, we may replace one or two of these trips with prepared labs. You will work in groups to identify what you collect and produce herbarium reports based on the results (see “Herbarium Project” handout to come). The field trips will occur during the lab periods on Tuesdays, starting in late August and possibly as late as mid-October. On field trip days we may leave earlier than the official beginning of lab period! I may change the dates of field trips based on the weather and availability of specimens.

Clothing: Tuesday field trips are mandatory and will be canceled/postponed only if the weather is very bad. We will proceed with trips in light-to-moderate rain, so make sure you are prepared with wet-weather clothing. We will be on easy trails, but there may be poor footing, and, if we are lucky, mud. So wear strong, closed-toed shoes with good traction, that you do not mind getting dirty.

Evaluation

Grades will be based on the following percentage scale. The total point value for the semester will depend on the actual number of assignments given, but will be in the range of 1250-1600 points.

Grade%
A 93-100
A- 90-92.99
B+ 87-89.99
B 83-86.99
B- 80-82.99
C+ 77-79.99
C 70-76.99
D 60-69.99
F <60

Points will be given for the following:

  1. Midterm exams (2 x 150 = 300 points): Two midterm exams will be given covering lecture AND lab material, on OCTOBER 5 and NOVEMBER 16. Each exam will be worth 150 points. Students generally take from 45-90 minutes to complete these exams; rarely do students need or want more time, but I will try to provide as much time as you need.

    Each exam will have at least two portions, a short-answer portion (about 75-80 percent of the total points) and a fill-in-the-blank portion. Most or all of the short-answer questions will be chosen from “study questions” (see below) distributed beforehand. The total number of study questions provided during a full mid-term exam period (August 22 to September 28; October 3 to November 9) will be 60-80; a proportional number will be provided for the remainder of the semester. Approximately ten of these study questions will be chosen for the full mid-term exams, and a proportionate number will be chosen covering the last three weeks of the course on the final exam. The fill-in-the- blank questions will mostly test your knowledge of terms and taxonomy.
  2. Laboratory reports (approximately 200-300 points total): For most laboratories, you must turn in a short report; a handout will usually be provided telling you what to include. Most of these will be worth ten to thirty points each and will be returned to you after grading.
  3. Fungal identification project (~200 points): You will collect fungi and identify them in the laboratory. More on this later.
  4. Term paper on a fungus or group of fungi (OPTIONAL: 200 points): More on this later.
  5. Study questions (approximately 150 points): You will be given “study questions” related to the lecture and lab material on a regular basis. These same questions will make up approximately three-fourths of the midterm exam material (see above). In addition, you will be given a “taxonomy table” listing all of the organisms covered in the course, organized taxonomically. Approximately every two weeks, you will turn in your answers to the study questions during class. A number of questions will be selected for grading. The questions will be returned to you during the lab period.
  6. Final exam (200 + 75 = 275 points total): The final exam will consist of two portions: 1) a portion structured like the midterm exams, covering the material covered from November 15 to the end of the course, worth 75 points, and 2) a multiple choice/matching/fill-in-the-blank portion that is cumulative, worth 200 points.

What is hard about this course: The amount of material covered is very large. If you do not 1) come to class, 2) take good notes, and 3) study on a regular basis to keep up, you will be overwhelmed. Trust me.

The good news is that despite the mammoth amount of material covered, students tend to do pretty well. The small size of the course encourages students to get involved and be fully engaged. Those that don’t participate fully tend not to do as well. This should be a fun class – fully engage yourself in it and enjoy this rare opportunity where you can interact with the instructors and your classmates. Most students do this.

Attendance

Your attendance will be noted every session. This is a small class, and I know who is present and absent on a daily basis. If you miss class for any reason, legitimate or not, it is a good idea to tell me why.

Missed exams and laboratories: Make-up exams will be given only in extremely special circumstances. Circumstances that do not warrant make-up exams include exams being given in other classes on the same day or travel for weddings or other non-emergency situations. Circumstances that may warrant make-up exams include bereavement, significant health issues, and crucial research or other academic activities. Most laboratory activities require special preparation and cannot be made up after the fact. Proof may be required for any excused absence. If you have a reason in advance for missing class, whether it is an acceptable excuse or not, it is important that you inform me of these things as far ahead of time as possible.

Flu Protocols: In compliance with Pennsylvania Department of Health and Centers for Disease Control recommendations, students should NOT attend class or any public gatherings while ill with influenza. Students with flu symptoms (respiratory symptoms accompanied by significant fever) will be asked to leave campus if possible and to return home during recovery. The illness and self-isolation period will usually be about a week. It is very important that individuals avoid spreading the flu to others.

Courtesy and Good Citizenship

Being on time: Lecture begins PROMPTLY at 1:35 p.m., whether you have arrived or not. You are expected to show up on time for every lecture. If you know you need to miss a class or lab for a legitimate reason ahead of time, let me know and I will do what I can to accommodate it. If you cannot make the 1:35 p.m. start time, I suggest that you take a different course.

Phones: Turn them off or to vibrate and do not use them during the lecture period. During lab period, as well as between lecture and lab, you may come and go as you please, but do not make or receive phone calls in the classroom – go out in the hallway.

Laptops and tablets: You must not use laptops or tablets except for legitimate classroom activities. The use of lecture or lab time for internet surfing or other illegitimate computer use will not be tolerated – it is rude, a distraction to your classmates, and very foolish if you want to do well in this course.

Academic Honesty: Students will work together in the laboratory, and study groups are encouraged both for answering study questions and for exam preparation. However, with the exception of group assignments specifically labeled as such, ALL material turned in must be the original work of each individual student, and students must not copy the work of other students, from websites, publications, or other material, either for the class projects or for the exams. Copying even portions of descriptions of Fungi or other published material for any projects is plagiarism. Such misrepresentation will be dealt with as a matter of academic dishonesty, which will result in any combination of a zero grade on the assignment, an F grade in the class, and/or disciplinary action by the university in accordance with the policies described below.

Penn State Statements

The Penn State Principles

The Pennsylvania State University is a community dedicated to personal and academic excellence. The Penn State Principles were developed to embody the values that we hope our students, faculty, staff, administration, and alumni possess. At the same time, the University is strongly committed to freedom of expression. Consequently, these Principles do not constitute University policy and are not intended to interfere in any way with an individual's academic or personal freedoms. We hope, however, that individuals will voluntarily endorse these common principles, thereby contributing to the traditions and scholarly heritage left by those who preceded them, and will thus leave Penn State a better place for those who follow.

Academic Integrity

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 in and outside of the classroom. 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, plagiarism, 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 and G‐9 Procedures.)

Code of Conduct and Student Conduct Procedures

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.

Nondiscrimination Statement

The University is committed to equal access to programs, facilities, admission and employment for all persons. It is the policy of the University to maintain an environment free of harassment and free of discrimination against any person because of age, race, color, ancestry, national origin, religion, creed, service in the uniformed services (as defined in state and federal law), veteran status, sex, sexual orientation, marital or family status, pregnancy, pregnancy-related conditions, physical or mental disability, gender, perceived gender, gender identity, genetic information or political ideas. Discriminatory conduct and harassment, as well as sexual misconduct and relationship violence, violates the dignity of individuals, impedes the realization of the University's educational mission, and will not be tolerated. Direct all inquiries regarding the nondiscrimination policy to Dr. Kenneth Lehrman III, Vice Provost for Affirmative Action, Affirmative Action Office, The Pennsylvania State University, 328 Boucke Building, University Park, PA 16802-5901, Email: kfl2@psu.edu, Tel (814) 863-0471.

Disability

Penn State welcomes students with disabilities into the University's educational programs. Every Penn State campus has an office for students with disabilities. The Office for Disability Services (ODS) Web site provides contact information for every Penn State campus. For further information, please visit the Office for Disability Services Web site.

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's 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.

Mental Health Services

Many students at Penn State face personal challenges or have psychological needs that may interfere with their academic progress, social development, or emotional wellbeing. 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.
