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.
17 pages, via online journal, Purpose: This quantitative study sought to investigate the perceptions of teachers and students regarding competency-based education (CBE) principles at the College of Agriculture at Razi University.
Design: This research is a comparative analysis of two groups. The first group consists of undergraduate and graduate students majoring in agriculture who are members and non-members of student cooperatives (n = 256). The second group consists of agricultural faculty members (n = 59).
Findings: The results of this study show that students and teachers have different views with regard to the extent to which CBE principles are practiced in the College of Agriculture. Moreover, students with different learning patterns had different perceptions regarding the extent to which CBE is practiced, whereas teachers with different teaching patterns had the same perception of the application of CBE principles in the College of Agriculture.
Practical implications: This study has practical implications for agricultural higher education in general and colleges of agriculture in particular. Colleges of agriculture across Iran could encourage their students to establish and engage in student cooperatives so that the ‘what’ and ‘how’ aspects of CBE are put into practice.
Theoretical implications: This study has theoretical implications for CBE principles. For example, student cooperatives can be utilized by faculty members as one of the main strategies for developing CBE in agricultural colleges.
Originality/value: This study is original in that it moves from theory to practice when considering CBE.
