Course Evaluation Descriptions: Participation and Online Meetings

 

This is an asynchronous online class, meaning that we have no required face-to-face meetings.  We will have some WebEx discussions (NCTC’s chosen live video service, like Zoom or Big Blue Button).  I have tentatively scheduled them for Thursday afternoons from 2:00 to 4:00.  These meetings are not required for discussion points because the course is classified as asynchronous.  They are for your learning benefit, and I recommend joining them if you can.  If your schedule doesn’t allow WebEx on Thursday afternoons, it may be possible to set up other online meeting times either individually or in small groups.  Please tell me what works for you as soon as possible.

 

Participation will be based instead on your contribution to online discussions.  We will have at least two weekly discussions.  One will be about the assigned readings and lesson, and the other will be your Disease Journal.  You must make at least two posts other than your Disease Journal to get full participation points, and one needs to be a response to a classmate (or to me).  On exam weeks, discussions may be about the upcoming exam. 

 

Participation is worth 150 points total.  Each post/response you make is worth 5 points (10 points/week).  Posts like “You are awesome!” or “Nice fungus!” are nice but don’t get points—you need to say something substantive. 

 

Original posts are due on Thursdays at 11:59 PM (aka. just before midnight).  Replies are due three days later, on Sundays at 11:59 PM.  

 

Disease Journal

 

Each week that you do not have an exam, you will have to find and photograph a plant with a problem and post it to our discussion board. The details of the assignment are in the first Module (Getting Started).  It will always be due on Thursdays at 11:59 PM.  Each post is worth 20 points, for a total of 200 points.  

 

Quizzes

 

Each week we have no exam, we will have a quiz about the material covered.  Quizzes will be posted under the weekly modules.  They will be open-book because I can’t stop you!  All quizzes will be 10-15 multiple choice questions with no time limit.  They will be due on Fridays at 11:59 PM.  

 

Quizzes are worth 10-15 points each (variable). 

 

Lecture Exams 

 

The lecture exams will include all notes, discussions from lecture, fieldtrips, labs, videos, and reading assignments. Lecture tests are cumulative in that they will draw upon concepts previously addressed in class, but the emphasis will be on material learned since the previous test. Exam questions will be multiple choice, fill-in-the-blank, short answer, and/or essay. If an exam is missed, a zero will be recorded in the grade book. There are no make-up exams.

 

Each exam is worth 100 points.  

 

Disease Report 

 

Each student will be required to research a local plant disease that they discover. The disease must be identified, photographed, and researched. Report must include the findings of the field work and control/remediation recommendations.  It will be due on _______.  

 

The Disease Report is worth 200 points.

COVID-19 Specific Syllabi Statements, Fall 2020

 

Some of the following does not apply to our online class-- but read it carefully! 

 

Syllabi statement regarding potential Conversion of Onsite Classes to Online/Remote Format:

 

North Central Texas College students should be aware that in the event of a college closure due to COVID-19, onsite classes will be converted to an online/remote format. Students should plan ahead to ensure they have access to the computer equipment (either PC, MAC, or tablet), webcam, and internet connectivity to continue their classes in an online/remote format. Please read all your official North Central Texas College student emails as the transition from onsite to online/remote might require a reorganization in your personal situation. Students will be granted a 72-hour transition and grace period. Online classes will continue as scheduled without disruption. Wear a mask, stay safe, and contact your Instructor as the situation arises. These policies and procedures were updated on July 30, 2020 and are subject to change.

 

Syllabi Statement Regarding Face Coverings:

 

Per the North Central Texas College guidance on face coverings on campus, in the instructional setting, faculty and students must wear face coverings, such as masks or face shields. Students without coverings, or those who do not comply with the rules relating to face coverings, will not be able to participate in on-campus classroom activities. To request an exception to this requirement, students should contact the NCTC HR Office of Enrollment Management (ccove@nctc.edu). Failure to comply with the face coverings requirement may result in the Instructor directing the student to leave the classroom. Any student asked to leave the classroom may be referred to the student conduct officer. These policies and procedures were updated on July 30, 2020 and are subject to change. 

 

Temporary COVID-19 Attendance Policy for Face-to-Face Meetings:

 

We are facing an unprecedented situation in which all of us must be flexible and make prudent decisions in the best interest of our families, our campus, and our community. In light of this, North Central Texas College is temporarily establishing the requirement that faculty keep records of student attendance for face-to-face course meetings as well as a documented seating chart. In addition, students who are sick or need to quarantine should not attend classes. Students will not be required to provide formal documentation from a health care provider and will not be penalized for COVID-19 related absences when proper notification to campus health officials is made in accordance with the guidelines stated below. 

 

Faculty will:

 

  • Notify students about important course information and delivery changes through Canvas and campus email.

 

Students should:

  • Provide notification to campus officials (via NCTC Daily Health Check protocol through Canvas) if they have tested positive for COVID-19 or have to quarantine so we can confirm reported absence with instructors, monitor, and assist the campus community.
  • Notify instructors in advance of the absence
  • Connect with that class through Webex if the class session is being transmitted in a hybrid fashion.
  • Keep up with and/or make up missed classwork or assignments.
  • Submit assignments digitally through Canvas or other means as announced by your instructor.
  • Work with their instructors to reschedule exams, labs, and other critical academic activities described in the course syllabus.
  • Check Canvas and campus email daily to receive important announcements pertaining to the course.

During this period, faculty with face-to-face meetings will establish assigned seating/work stations to facilitate roll-taking, and, if necessary, contact tracing. Additionally, we ask all members of the College community to be attentive to their health, and safeguard others, by following the CDC’s guideline to “stay home when you are sick.” You should stay home if you have symptoms. More information on what to do if you are sick is available at the CDC’s website. 

Additional NCTC information is available at http://www.nctc.edu/coronavirus/index.html

 

 

Student Handbook 

 

Students are expected to follow all rules and regulations found in the student handbook and published online. 

 

Disability Services (Office for Students with Disabilities) 

 

The Office for Students with Disabilities (OSD) provides support services for students with disabilities, students enrolled in technical areas of study, and students who are classified as special populations (i.e. single parents).Support services for students with disabilities might include appropriate and reasonable accommodations, or they may be in the form of personal counseling, academic counseling, career counseling, etc. Furthermore, OSD Counselors work with students to encourage self- advocacy and promote empowerment. The Counselors also provides resource information, disability-related information, and adaptive technology for students who qualify. If you feel you have needs for services that the institution provides, please reach out to either Wayne Smith (940) 498-6207 or Yvonne Sandman (940) 668-4321. Alternative students may stop by Room 170 in Corinth or Room 110 in Gainesville. 

 

Academic Dishonesty 

Scholastic dishonesty shall include, but is not limited to cheating, plagiarism, academic falsification, intellectual property dishonesty, academic dishonesty facilitation and collusion. Faculty members may document and bring charges against a student who is engaged in or is suspected to be engaged in academic dishonesty. See Student Handbook, “Student Rights & Responsibilities: Student Conduct ([FLB(LOCAL)]”. Consequences for academic dishonesty are detailed in the Student Handbook.

Attendance and Tardiness Policy

General NCTC Attendance Policy

Regular and punctual attendance is expected of all students in all classes for which they have registered. All absences are considered to be unauthorized unless the student is absent due to illness or emergencies as determined by the instructor. It is the student responsibility to provide documentation as to the emergency for approval and judgement by the faculty member. Approved college sponsored activities are the only absences for which a student should not be held liable and only when provided by a college official ahead of the absence. Valid reasons for absence, however, do not relieve the student of the responsibility for making up required work. Students will not be allowed to make up an examination missed due to absence unless they have reasons acceptable to the instructor. A student who is compelled to be absent when a test is given should petition the instructor, in advance if possible, for permission to postpone the exam. Student will be dropped from a class by the Registrar upon recommendation of the instructor who feels the student has been justifiably absent or tardy a sufficient number of times to preclude meeting the course’s objectives. Persistent, unjustified absences from classes or laboratories will be considered sufficient cause for College officials to drop a student from the rolls of the College. From Board Policy FC (LOCAL) 

 

Course-Specific Attendance Policy:

This is an asynchronous online class. Attendance will be calculated based on online participation on discussion forums.  This is an important part of your grade.  Late posts will receive zero points (though you are welcome to make later contributions to discussions!)  If you do not make any posts for a week, you will be recorded as absent for that week.  For every three absences, the student’s final grade will drop by one letter. 

 

If you do not participate in online activities for a consecutive three weeks, you might be dropped from the CANVAS roster (blocked in CANVAS) and might be dropped from the class.

 

If you are having difficulties with Internet access that are affecting your ability to attend, please contact me to discuss the problem.  

 

Because the class is asynchronous, in-person tardiness is not an issue. 

 

Other Policies and Pertinent Information

Emailing the Instructor 

After the first week of class, all correspondence with the instructor should be done through the Canvas course mail system rather than through the NCTC email system. 

 

Missing Assignments

Make-up assignments may be allowed for reduced points on a case-by-case basis, with instructor consent.  Please contact the instructor with questions.  

 

Disruptive Behavior 

A student who engages in any behavior or language in the classroom—in this case, the online classroom--that intentionally or unintentionally disrupts the learning process will be asked to leave the class and may be reported to the Vice President of Instruction for disciplinary action. No garden trolls, please!

 

Grade and Attendance Records 

All grades and attendance/tardy records will be posted in Canvas and can be accessed at any time during the semester. If you see a problem or have a question, please contact me as soon as you can. 

 

Missing Classes

Each class—in this case, each weekly module and set of lessons-- is assigned participation points. If a student misses a class, participation cannot be earned. There are NO MAKE-UP participation points, though the materials will still be accessible on Canvas for your reference. 

 

Late Work

Late work will not be accepted. All assignments not turned in by the due date will be given a zero in the grade book. If you are having problems accessing the online class, please contact me as soon as you can to discuss a solution.  Computer problems are not generally an acceptable reason for late work.  

 

Tobacco Products 

This is an online class, and you can do whatever you want in the privacy of your home.  However, because this is Plant Diseases class, please review the following statement from NCTC Horticulture and consider its relevance for our course: 

 

Please do not bring tobacco products or any containers that might have tobacco byproducts in them into the classroom, the gardens, or the Gainesville Greenhouse. See Tobacco Free Campus Information Policy. If you do use tobacco products, always wash your hands withsoap and water before entering the greenhouse (Gainesville) or touching any plants.

 

Study and Preparation Time

This is a 3-hour credit class. In general, students should expect to spend 2-3 hours studying for each credit hour of a course. 

 

Notes

In general, it is the student’s responsibility to take notes during class, lab, and fieldtrips. In this online course you may take notes, or not, according to your study preferences.  You will have access at all times to the course online, but you may wish to make additional notes.  This is your choice and responsibility. 

 

Web Browser

Take note that it is best to use Firefox or Chrome as your browser when accessing Canvas. 

 

Extra Credit

There may be extra credit opportunities in this course, but none are currently determined.  Stay tuned for updates. 

 

Curving Exams and Final Grades

No grades whatsoever will be “curved” in this course.  You will earn your grades based on merit, not by comparison to your classmates. 

 

Lab Attire, Physical Nature of Activities, and Weather Factors

You may wear whatever you want while accessing this course online.  However, as a horticulture class with a lab element, you will have assignments requiring outdoor activity (your Disease Journals and Disease Report).  Be prepared to complete these assignments regardless of heat, cold, wet weather, insects, etc.  If you need to use any tools to collect or dissect specimens, use all appropriate caution. 

 

Remember, there is no such thing as bad weather, only poor choices of clothing.  

 

Receiving Communication from your Instructor

Students can receive instructor announcements via texts and/or to their personal email accounts. To activate this setting, go to your Canvas profile, and enter in how you would like to receive communications. 

 

Tobacco-free Campus Information

NCTC restricts the use of all tobacco products including cigarettes, cigars, pipes and smokeless tobacco on campus property. NCTC is aware that tobacco use influences underage students, accumulates unsightly tobacco litter, and interferes with assuring clean air for all who come to NCTC. NCTC recognizes the health hazards of tobacco use and of exposure to second-hand smoke. Information on a tobacco cessation program is available for students, faculty, staff who wish to stop using tobacco products. We would like to "thank you" for your help in making our campuses Tobacco-Free. For questions or concerns please contact the Office of Vice President of Student Services at (940) 668- 4240. 

 

Toxoplasmosis

Toxoplasmosis is caused by the protozoan (one-celled parasite) Toxoplasma gondiiDangers to an unborn child from toxoplasmosis include birth defects and fetal death. The disease can be passed to people through contact with cat feces, and exposure is possible through contact with contaminated soil. Pregnant women should wear gloves when gardening or working in soil or sand, as it may have been used by neighborhood cats and contain cat feces. Any foodstuffs from the garden (fruits, vegetables, herbs, etc.) should be washed thoroughly before ingestion.
