4 pages., Via online journal., Interactive web-based questions were developed for students to review
subject matter learned in an online plant propagation course. Articulate Storyline
software was used to build nearly 250 review questions with five different testing
styles to ascertain proficiency in subject areas, including the biology of propagation,
the propagation environment, seed propagation, vegetative propagation, micropropagation, and cell culture. Questions were arranged to correspond to the
supporting textbook chapters in Hartmann and Kester’s Plant propagation: Principles and practices, ninth edition. These are open access and available to instructors
and students worldwide. Users received immediate feedback for each question
answered correctly or incorrectly. The system remembers where one leaves off,
which enables starting and stopping multiple times within a chapter. Means of preand posttest responses to nine content knowledge items showed that students
perceived a significant content knowledge gain in the course. These online interactive reviews can be adapted easily to other courses in a variety of fields,
including horticulture, botany, systematics, and biology. They can also be expanded
to overlay multiple objects and trigger events based on user response. Since inception,
the website hosting these online reviews averaged 156 unique visitors per month.
Students have reported this to be a useful tool to prepare them for course exams.

9 pages., Via online journal., Negative impacts from invasive species present a global problem. Consequently, invasive species biology has emerged as an important subdiscipline of conservation biology. One of the goals of invasive species biology is to educate the public about impacts and potential control of invasive species. The purpose of this study was to determine if a lecture, a lecture and laboratory learning model, or both influence college student learning gains and whether increase in knowledge results in changes in attitudes about invasive species. A pre- and posttest instrument that measured knowledge and attitudes of invasive species was administered to several different classes of students at a university and community college. One group of students received a lecture and laboratory curriculum between the pre- and posttest (the lecture and laboratory treatment group). A second group of students received a lecture between the pre- and posttest (the lecture-only treatment group) and a third group received no instruction between tests (the control group). The lecture was in the form of an electronic presentation, whereas the laboratory curriculum included a case study, a visual aid, and a scavenger hunt to educate students about examples of invasive plant and animal species. In all classes and groups, there were at least 2 weeks between administering the pre- and posttest. Results showed that the control group scores were not different between the pre- and posttest. However, both the lecture-only and the lecture and laboratory treatment groups had scores that changed after receiving the curricula. In addition, there was an effect of curricula on student learning for the three conditions. The differences between the group that received no curricula vs. the two that did indicated that the curricula were effective teaching interventions to help students become more educated about invasive species.
5 pages., Via online journal., Food security is a growing global concern. To meet the needs of an ever-growing population, food production practices will need to evolve to maximize food quantity and quality. Controlled-environment food production has increased significantly in the United States over the past 5 years, and a component of that production includes hydroponic food crops. In an effort to better prepare a workforce with knowledge of hydroponic crop production, a new course was added to an existing greenhouse curriculum. A service-learning project was integrated in the course that allowed students to experience both growing crops hydroponically and volunteering at a local food bank with a free meal program. Self-assessment showed a significant increase in student confidence in understanding food security by the end of the course. There was also a significant knowledge gained in defining terminology, factors, and the impact of food security in a community. The three guided reflections students completed during the course identified four common themes relative to the course content and service-learning project including the following: community benefits, value of volunteering, local and global effects of food insecurity, and personal growth.
3 pages., Via online journal., Increased global trade coupled with diversified employment opportunities demand college graduates possessing well-developed professional skills. Recent survey results identified the importance of professional skills among candidates seeking employment, with communication being recognized as the most important skill or quality when selecting candidates. The ability to work within a team structure, solve complex problems, and organize and prioritize work also ranked high among industry employment needs. Despite a rigorous focus on discipline-oriented knowledge and skills, development of professional skills in students of horticulture may be overlooked or not fully developed. Teaching methods can be modified to incorporate development of professional skills and discipline-oriented knowledge to enhance student employment preparedness and directly address industry needs.
7 pages., Via online journal., The purpose of this study was to determine college students’ understanding of invasive species and their support for plant and animal pest control and eradication methods. Surveys were administered at a university and community college in Texas in biology and agriculture departments. A total of 533 respondents participated in the study. Most students said they were not part of any type of environmental organization and felt they were not very informed about invasive species issues. More students reported learning about invasive species in high school than in college courses. The average score on knowledge questions related to invasive and native plants and animals was 32%. Most students underestimated the negative impact of invasive species but many were aware of costs to manage those species. Reliable reported sources of information included environmental organizations, college courses, and the Internet. Pearson product-moment correlations showed positive relationships between students who had college class instruction regarding invasive species and positive attitudes toward management of invasive species. Positive relationships were also found between instruction and an awareness of invasive plants or animals. Respondents who were knowledgeable of invasive species in the community had more positive attitudes toward the management of invasive species. In demographic comparisons, differences were found with males, upperclassmen, and those identifying as Caucasian or other having more knowledge of invasive species and more positive attitudes toward their management.
4 pages., Via journal article., Learning by doing plays a critical role in a learner’s conceptual understanding. By actively engaging with a concept, students gain experience and develop an enduring understanding of the concept. The concept of pollen viability is a critical component in the field of plant breeding and can be used to explain various aspects of pollen quality. An inquiry activity was designed to expose undergraduate students in a horticulture course to the concept of pollen viability and its application. The entire class was tasked with collaborating to identify an in vitro germination medium optimized to germinate plumeria (Plumeria rubra) pollen. To determine optimum sucrose and pH concentrations of the medium, student groups were assigned treatments of pollen from two plumeria cultivars that were germinated in Brewbaker and Kwack media of differing sucrose and pH concentrations. Students calculated the percentage of germinated pollen and assessed pollen tube integrity and used these variables as evidence of an optimized medium. Although undergraduates were engaged in authentic research practices during the inquiry activity, lack of time and resources impeded completion of the activity. However, students were exposed to methods and instrumentation directly related to evaluating pollen viability. Moreover, they were exposed to the basic practice of pollen quality assessment that they can use to carry out investigations on pollen fertility. In addition, insight was gained to improve the inquiry activity in the future. Now, well-informed modifications to the inquiry activity can be made to pilot this activity in a formal horticulture laboratory section.
3 pages., Via online journal., Student engagement in the classroom is critical for effective learning. To enhance student engagement, several teaching approaches can be used, including a flipped classroom approach and virtual field trips. The flipped classroom approach was used in an undergraduate tropical production systems course in which students viewed lecture materials outside of class, brought their smart devices to class to review materials, searched for new information on the Internet, and participated in small group discussions. In the virtual field trip assignment, each student visited a commercial farm or nursery, interviewed the owner or manager, and gave a presentation to the class about the operation of the enterprise and its sustainable practices.
6 pages., Via online journal., This study examines the impact of a residential horticultural career academy, Camp Tomorrow’s Undergraduates Realizing the Future (TURF), conducted from 2010 to 2016 at Oklahoma State University (OSU) in Stillwater, OK. Each year, up to 25 Oklahoma high school students were engaged in 2 weeks of hands-on activities representing a variety of horticulture-related careers. Instructors for Camp TURF included OSU faculty, staff, and graduate students from the Department of Horticulture and Landscape Architecture, related OSU departments, and horticulture and landscape architecture industry professionals. The Oklahoma State Regents for Higher Education sponsored this career academy, which was geared toward potential first-generation college students, and helped to expose students to the university atmosphere as well as expand their knowledge of science- and math-related career fields. Pre- and postassessments given at Camp TURF show significant changes in college readiness and familiarity with horticulture careers, but did not necessarily increase interest in particular horticulture and landscape architecture careers. Upon following up with academy graduates, we learned that the academy has been a positive experience for numerous attendees, with 76.6% going on to higher education and two students majoring in horticulture and landscape architecture-related areas.
