Current Topics and Methods Courses

Check out topics we've recently covered, as well as topics we plan to cover soon in our Current Topics (HCS 8830) and Methods (HCS 7806) Courses:


Spring 2024

HCS 7806: Publishing in the Tri-Society Journals

When: Full semester SP24

Instructor: Laura Lindsey (lindsey.233@osu.edu)

The purpose of this methods course is to understand publishing guidelines of Tri-Society journals, including Agronomy Journal, Crop Science, Agricultural and Environmental Letters, and Crop, Forage, and Turfgrass Management, and produce a draft publication that will be submitted to one of these journals. Students should have data analyzed prior to taking this course. New students will be permitted to write a literature review instead of a journal article. 


Autumn 2023

HCS 7806: Using SAS for applied research analysis

Instructor: Alex Lindsey (lindsey.227@osu.edu)  

The purpose of this methods course is to help students understand how to use SAS to effectively analyze data collected from field research trials. Students will be expected to have their own datasets to use for the class. Focused analysis techniques will be defined by the students, and may include designs such as RCBD, split-plot RCBD, RCBD with subsamples, and (potentially) repeated measures. Students will gain experience operating the MIXED and GLIMMIX procedures, in addition to possibly the REG, NLIN, and CORR procedures.

SUmmer 2023

HCS 8830: TBA

Instructor: Kristin Mercer (mercer.97@osu.edu) & Lev Jardón Barbolla

This course will provide an interdisciplinary approach to understand domestication as an evolutionary process of adaptation towards enhanced use value, mediated by the niche construction process. With emphasis on crop plants, we will review the impact of domestication in different levels of organization, from genetics to life history traits and domestication above the organism level (i.e. landscape, agroecosystem). The course aims to bring a historical perspective of the domestication process and its intertwining with the diversity of agricultural practices. Students will be required to present summaries of 1-2 papers and lead subsequent discussions.

HCS 8830: College Teaching Strategies and Perceptions

HCS 8830: Plant Resistance

When: Second half of AU22

Instructor: David Francis (francis.77@osu.edu) 

A literature-based course exploring the history and contemporary understanding of plant resistance to disease. We will begin by an exploration of the "gene-for-gene" hypothesis, continue through the cloning of resistance genes, touch on the ecological, evolutionary, epidemiological implications, and conclude with the current understanding that immune functions characteristic of plants represent a conserved mechanism that functions across kingdoms.

HCS 8830: Habits for Professional Success

When: Full semester AU22

Instructors: Wendy Klooster (klooster.2@osu.edu)Andrea Gschwend (gschwend.2@osu.edu) & Guil Signorini (signorini.2@osu.edu)

The course will use the bestseller “The 7 Habits of Highly Effective People” by Stephen Covey to engage students in discussion of strategies to develop productive and deliberate habits. This course will create an honest and fertile environment to discuss potential approaches to improve professional habits, such as proactivity, time management, and collaboration, and introduce new behavior in one’s routine. This course will focus on habits that specifically benefit research and academic outcomes but engaged participants may experience positive impacts in multiple dimensions of life.

HCS 7806: Data Visualization in R

When: Full semester AU22 (Tuesdays 3:55-5:45pm)

Instructor: Jessica Cooperstone (cooperstone.1@osu.edu) 

This course aims to introduce students to the principles and practice of data visualization. Students will learn fundamental principles of data visualization and create figures that appropriately and ethically represent their data. Data visualizations will be created in the R programming environment, using tools including the grammar of graphics implemented in ggplot2. In the process of creating visualizations, students will also become familiar with data handling and wrangling in R.

You do not need to be an R expert for this class, but I will assume working-level knowledge of R programming. If you have no experience with R, but would still like to take this class, you can. I ask then you get yourself up to speed by taking this free online class https://www.edx.org/course/data-science-r-basics (audit only) before the start of the 3rd week of class. Tips and tricks in R will be scattered throughout the course material.

Spring 2022

HCS 7806: Publishing in the Tri-Society Journals

Instructor: Laura Lindsey (lindsey.233@osu.edu)

The purpose of this methods course is to understand publishing guidelines of Tri-Society journals, including Agronomy Journal, Crop Science, Agricultural and Environmental Letters, and Crop, Forage, and Turfgrass Management, and produce a draft publication that will be submitted to one of these journals. Students should have data analyzed prior to taking this course.

HCS 7806: Hydroponics Crop Production Methodologies

Instructors: Chieri Kubota (kubota.10@osu.edu) & Mark Kroggel (kroggel.4@osu.edu)

Greenhouse laboratory course for graduate students who are interested in learning modern crop production methodologies to consider in their research. The course will provide hands-on practices of greenhouse hydroponic crop production – leafy crops, tomato, and more using crop production facilities similar to commercial production settings. Students will also learn greenhouse environmental sensors and data interpretations. This course is for graduate students to learn the methodologies but the greenhouse laboratory setting is shared with another course for undergraduate student (HCS 4301 Hydroponic Crop Production Lab).  Therefore, interactions with HCS 4301 students are expected through the course. 


Autumn 2021

HCS 8830: Habits for Professional Success

Instructors: Andrea Gschwend (gschwend.2@osu.edu), Wendy Klooster (klooster.2@osu.edu) & Guil Signorini (signorini.2@osu.edu)

This course steps out of the usual technical/analytical training in horticulture & crop science and attempts to guide students on developing behavioral and interpersonal skills. The course will use the bestseller “The 7 Habits of Highly Effective People” by Stephen Covey as point of departure. Students will engage with three HCS faculty members and discuss strategies to develop productive and deliberate habits. There are challenges in recognizing weaknesses in one’s personal habits and turning them into opportunities for improvement; however, this course will accomplish this goal by creating an honest and fertile environment to discuss potential approaches to improve professional habits, such as proactivity, time management, and collaboration, and introduce new behavior in one’s routine. This course will focus on habits that specifically benefit research and academic outcomes, but engaged participants may experience positive impacts in multiple dimensions of life.

Spring 2021

HCS 8830: Cover Crops in Midwestern Cropping Systems

Instructor: Mark Sulc (sulc.2@osu.edu)

In this current topics course, the students will explore and discuss the peer-reviewed literature to identify what is known concerning the use of cover crops in agronomic cropping systems. The focus will be on grain crop systems in the Corn Belt region but examples from other regions will be considered that inform the potential of cover crop use in this region. We will answer such as questions as, what are the benefits of cover crops and what are the opportunities and challenges for using cover crops within our grain cropping systems? Possible topics to explore include: effects of diversifying cropping systems with cover crops (eg. environmental and subsequent crop effects), managing cover crops for weed, insect, and disease control within cropping systems, cover crop species selection, rotational strategies for cover crop incorporation into cropping systems, establishment and termination of cover crops, economic considerations of cover crop use, soil benefits of cover crops, and options for generating additional income from cover crops.
