6 pages., Via online journal., Based on a survey of the American Society for Horticultural Science (ASHS), membership need was identified for an online peer review system to validate innovation and recognize excellence in science-based teaching and extension scholarship for promotion and tenure purposes. This system would also provide a clearinghouse for instructional materials of merit for use in classrooms, laboratories, and outreach education, which fall outside the parameters of the three academic journals of ASHS. It was determined HortTechnology already provided a valued outlet for peer review of manuscript style teaching and extension scholarship; however, a need was identified for a mechanism to provide peer review of instructional materials which did not conform to a traditional manuscript format. Herein we describe the process that led to the development and launch of HortIM™, a new peer review system for teaching and extension instructional materials. An online peer review process for juried assessment of instructional materials such as articles, bulletins, case studies, fact sheets, instructional videos, teaching modules, and laboratory exercises was developed. A beta test of initial solicited materials in each category was piloted resulting in an initial database of these scholarly materials. This activity culminated in an initial opening of the system for submissions in Fall 2016. This article documents the development of HortIM™, including the submission and review process.
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.
