| Summary: | 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. |
