Achieving consensus Deal with Methodological Issues in the Delphi technique

Delphi is a powerful technique used to seek answers to appropriate questions. The purpose of this paper is to provide an overview of the Delphi technique as a research method. This paper discusses the scientific merit of the Delphi technique by investigating on 41 studies of Journal of Agricultural Education from 1981 to 2013, and 2 studies of Journal of Agricultural Science and Technology. The results showed that there is no general agreement on using indexes in different rounds of Delphi technique; however, according to the frequencies of using indexes in different studies, the following suggestions are presented. The favourable number of panel of experts is between 10 to 20. Purposive sampling method is used for selecting the panel members. Usually a three rounds of Delphi method is used. One question is designed in round one. Mean and standard deviation indexes are used for passing from round two to round three and agreement level of 70 present is used for achieving expert's consensus in round three

Teachers and students’ perception of competence-based education in the agricultural higher education system (Case of a student cooperative in Iran)

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.</p
