Midterms: Midterm questions will cover lecture and activity/lab material, including virtual field trips. Final exam. The final exam will be given at the university designated time: Monday April 29 4:00 – 5:45 (Most of the material will be that covered since 2nd midterm but ≈25% of the questions will be comprehensive in the sense you will be asked to incorporate concepts learned during entire semester). Make-up Exams: When a midterm or final exam is must be missed for a legitimate reason and the instructor is notified in advance, the test will be rescheduled for that individual. In case of verifiable emergency such as sudden illness, death in family, or transportation problem, the test will be rescheduled for that individual. For all other reasons, a make up test worth 75% of the original exam (i.e. 75% is the maximum grade that may be scored on the test) may be taken by the student. The exam must be taken by the date established by the instructor. Student Crop Growing Guides and Presentations: The 14th week of the quarter, the class will be responsible for presenting the growing guides for crops. These crops will be selected by the class the 8th week of the semester. Each crop guide will be researched by a team of 2-3 students and the team will present the information orally and also prepare a written growing guide to be given to the members of the class for reference should they find themselves growing these crops in the future. The oral report will include a brief discussion of the sustainability of the recommended practices. A PowerPoint presentation is OK for the presentation but is not acceptable as the growing guide. The growing guide must include at least 4 references notated in proper format (you will be given the format to use) at the end of the guide. Two (2) of these must NOT come from an unreviewed internet site such as a business website though they can come from a document located by an internet search or documents available online that go through an editing and/or review process (e.g. university fact sheets, research journals articles, trade journals articles). Student Grown Crops and Growing Log: At the appropriate time in the semester, students as individuals will sow seeds for the crops that student will be responsible for growing during the quarter. Responsibilities include but are not limited to: transplanting at the proper time, moving plants from the propagation house to the growing house at the right time, applying water and fertilizer as needed during the growing phase during the week (greenhouse staff will water on weekends), applying growth regulator as needed, and reporting any diseases or insects found so they can be treated. Each student will keep a detailed chronological log of actions taken with the crop that includes reasons for the action taken. The details include but are not limited to: ü planting and transplanting dates ü weekly summary of weather conditions and events ü irrigation, fertilization, and growth regulator application dates ü weekly summary of observations on the growth and development of the seedlings, ü greenhouse temperature set-points ü observations of problems ü any additional information you think would be useful to you as a grower. At the end of the semester students will present their plants and discuss the appearance of the plant and how the growing conditions affected that appearance. 3

Attendance and Missed Work: ¾ Attendance is required. Your plants are dependent on you and what you are learning!! You are allowed 3 absences, excused or unexcused. After that you will lose 1.0 point off your final grade for each absence, excused or unexcused. Think of this as a real job and there are consequences for excessive absenteeism, even if the reason for the absence is legitimate. Attendance will be taken in various ways at various times during the class period, if you are not there at the time attendance is taken, you will be counted absent. D Missed in-class assignments, activities, and quizzes cannot be made up. C Missed exams and out-of-class assignments can be made-up with no penalty with an acceptable and verified excuse. Unless there is a very compelling reason why the deadline cannot be met, the assignment or exam must be completed before I hand back the graded item – generally 1 week after taken/due. D Missed exams and out-of class assignments with no acceptable excuse can be made-up but with a deduction of 25% from the grade. After the conclusion of the 2nd class period following the exam or assignment due date or the item has been handed back, whichever comes first, the exam or assignment cannot be made up. The instructor will determine the date by which the final exam must be taken based on when the exam is originally scheduled in relation to when grades have to be turned in. Class Participation: Students will be given many opportunities to speak up in class and are strongly encouraged to interact with the instructor and other students in lectures and labs. Students should feel free to work cooperatively on their growing projects, midterm preparation, etc. However, each person is ultimately responsible for his or her own work.

Students are graded individually and overall grades are not based on a bell curve. In other words, you are not competing among yourselves for a limited number of A’s. I feel that this method of grading encourages cooperation among students) * In most cases this will be a team grade. If a team member/s fails to do his or her part, the problem must be brought to the instructor’s attention by the team. The instructor will attempt to work with the member/s to correct the problem. It the problem persists then individual grades may be assigned for the presentation and project, with the offending member/s receiving an appropriately 4

lower grade. If the problem is not brought to the instructor’s attention or brought with no time to correct the situation, all team members will receive the same grade. Not showing up for the presentation will result in a 0 for presentation for the non-presenter.

Disability Accommodations Students impacted with a disability are encouraged to inform the instructor at the beginning of the term. We will work with the Office of Disability Services (150 Pomerene Hall, 1760 Neil Ave., Phone 614-292-3307 TDD 614-292-0901, http://ods.ohio-state.edu) to provide the necessary accommodations. Temporary disabilities that result from injury or illness during the semester will be accommodated as needed. ************************************************************************************ Conduct and Academic Integrity Respect will be given by and for all participants in the class at all times. H&CS 5521 is a class with many components that put the student in situations where individual and team effort is required. Students will put forth the appropriate kind of effort for each situation. In all situations, any external sources of information will be credited in the proper format. Disruptive or dishonest acts such as cheating or plagiarism will be handled in accordance with procedures defined in the Code of Student Conduct (http://studentlife.osu.edu/csc) or Faculty Rule 3335-5-487. ************************************************************************************

Objectives 1, 3, and 4 are met because students are responsible for acquiring, evaluating, organizing, and disseminating information from basic sciences and translational plant sciences for their production guides as well as for other activities in the class. Also, students are required to communicate in a professional manner using different formats throughout the course, but especially in the presentation of a professional quality growing guide. Objectives 2 and 8 are met because throughout the course sustainability and social responsibility are stressed as part of the decision-making that goes into greenhouse crop production. Students are also required to include an assessment of the sustainability of the practices they recommend in their growing guides. Objective 5 is met at the intermediate level because students will be learning not only how to manipulate the greenhouse environment to control plant growth but the basic principles of making the greenhouse a viable business with such practices as crop scheduling to meet selling dates, planning workload and labor needs, the terminology commonly used in greenhouse enterprises, etc. Objective 6 is met at the advanced because creating the growing guide shows them not only how to do that, but also makes them realize the necessity of being able to do that. They also learn the necessity of keeping up the latest research information and technological advances. 6

Objective 7 is met at the intermediate level because students learn about the vast array of species used as ornamental plants, the value of growing unusual plants for niche marketing. Through the embedded topic that runs throughout the lectures of the need for employing and managing a workforce that is often from different cultures they learn to appreciate and treat the workers from those cultures with respect.
