The basic purpose of this study is to determine the varying effect
sizes of teachers’ perception and opinions about organizational
citizenship behavior in accordance with their seniority. 17 studies
deemed meeting the inclusion criteria were chosen from 30 MA
and PhD theses and dissertations in YOK National Thesis Archive
dealing with teachers’ opinions about organizational citizenship
behavior in Turkey to be used in this study. Total number of
samples in this study is 8432 (teachers); 3448 of which are teachers
with 1-10 years of seniority where as 4984 of which are teachers
with 10 and above years of seniority. In addition, several variables
such as publication year, the region used for the research,
educational level, scale type and researcher’s gender that could not
be included in the evaluation as a moderator in primary researches
were analyzed. In accordance with the results of this study, an
effect size with statistical significance at an insignificant level was
determined on the part of teachers with 11 years of seniority and
over according to fixed effect model (d= -0,133) and random effect
model (d=-0,180). In the consequence of the moderator analysis
conducted, moderator effects of the region in which the research
was conducted (p=0,000), educational level (p=0,002), the scale
type used in the studies (ready or developed) (p=0,000) and
researcher’s gender (p=0,018) were determined. Moreover, effect
sizes obtained from the studies showed that seniority difference has
a tendency to increase by year. As a result, seniority may not be
recommended to be used as a significant variable in those future
studies dealing with teachers’ opinions about organizational
citizenship behavior.
