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.

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.
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.
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.

12 pages., Via online journal., Advances in precision agriculture technologies provide opportunities to improve the efficiency of agricultural production systems, especially for high-value specialty crops such as fresh apples (Malus domestica). We distributed an online survey to apple growers in Washington, New York, and Michigan to elicit stakeholder perceptions of precision agriculture technologies. Findings from this study demonstrated that growers are willing to adopt precision agriculture technologies when they receive results from applied research projects and are engaged with active extension programs. The availability of customized services and purchasing and rental options may minimize the effects of the economies of size that create barriers to adopting increasing access to technologies. Finally, respondents deemed collaborative efforts between industry and academic institutions crucial for adapting the innovation to better address the needs of growers.
6 pages., Via online journal., Plant Madness was a classroom activity developed and implemented for the Landscape Plants II identification course at Kansas State University. The game was modeled after the National Collegiate Athletic Association college basketball March Madness tournament and Bracketology. One activity objective was to provide students an opportunity to learn new and recent cultivars and plant species not specifically covered in the class curriculum. The activity also provided students opportunities to practice public speaking skills, an avenue to be creative, and simply have fun in class. In Plant Madness, each student randomly drew a plant from a hat and then students were randomly assigned tournament seed rankings (preliminary rankings). On specified game days, one student played against another student, each having 2 minutes of play. Student play varied, and consisted of defining different plant attributes, landscape appeal, and interesting facts, for example; or identifying the opposing student’s plant’s faults through riddles, poems, games, songs, or simply recitation. Referees (e.g., guest faculty, graduate students) reviewed student play and awarded points, and the student with the highest score advanced to the next round through the single-elimination tournament. A postactivity survey was administered [Spring 2016 and 2017 (n = 44)] to obtain student feedback. When asked if the students liked the activity, it was nearly unanimous, 98% liked Plant Madness. Similarly, most students (93%) self-reported the activity increased their awareness of new or recent plant cultivars. When asked to rate the activity compared with other class approaches for learning different plants based on a scale of 1 (excellent) to 5 (poor), the average rating was 1.8. Students’ average rating for their ability to be creative for Plant Madness was 1.8 (1 = to a large extent, 5 = not at all). Ninety-five percent of the students recommended repeating the activity.
7 pages., Via online journal., Virtual plant walk maps were developed for an ornamental plant identification (ID) course, with the goal of providing an additional study resource to potentially enhance student learning. The maps provided students an opportunity to revisit plants covered in lecture and laboratory sections at their own convenience, using either a computer or mobile device. Each map plotted the locations of the plants from the corresponding list and provided photographs of specimens, plant family, common and scientific names, and plant type information. At the end of the course, a survey was given to collect information about student use and perceptions of the virtual plant walk maps for two fall semesters (n = 87). Survey results indicated 63% of the students used the virtual plant walk maps as a study resource. Students who used the maps reported accessing the maps an average of 3.2 times between receiving the maps and taking the plant ID quiz in laboratory. Students mainly used the maps to study the most current plant list and accessed previous plant list maps to a lesser extent. About 67% of students who used the virtual maps, used the maps to visually review the plants online only, although 31% of students used the maps for both visual review and to physically retrace the plant walk to view the live specimens. Of the students who did not use the maps, most found other study resources/methods more useful or they forgot about the maps as a resource. When asked to rate usefulness of the maps on a scale from slightly useful (1) to very useful (3), 43% of students indicated that the virtual maps study tool was very useful, 25% indicated the maps were useful, and 8% indicated that the maps were slightly useful. A significant dependence between student use frequency and student usefulness ratings of virtual plant walk maps was observed. As students’ use of the virtual maps increased, they perceived the maps to be more useful to their studies in preparing for ID quizzes. No differences between plant ID quiz scores were associated with virtual plant walk map use, learning style, or use by learning style. Our survey indicated that students used the virtual plant walk maps as a resource and perceived the maps as a useful tool in preparation for ID quizzes.
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.
