Meta-Analysis Of Research Findings On Effects Of Teaching Methods On Academic Achievement Of Agricultural Science Students:- Charles N. Agbaegbu
Abstract
This study investigated research findings on
effects ofteaching methods on academic achievement ofAgricultural Science
students. Meta-analysis survey design was utilized. Three research questions
guided the study. The population ofthe study comprised all previous
empiricalresearch findings on the effect of teaching methods on academic
achievement of Agricultural Science students. A coding sheet was developed by
the researchers to collect the necessary data required for the analysis. Data
collected were analyzed using percentages, mean and standard deviation to
determine the effectsize in relation to the research questions. Results of the
study showed thatthe effectsize forthe 13 studies was 0.63, indicating a high
effect size; the magnitude of the effect size associated with the designs ofthe
previous studies ranged between 0.28 and 0.98, with one shot case experimental
study possessing the highest effect size (0.83). Also, the effectsize
associated with sample size ofprevious studiesranged from 0.58 to 0.78, with
the sample size 99-160 having the highest effect size (0.86). Recommendations
were made among which is that metaanalysis procedure should be used in
aggregating results of previous studies that share common research questions/
hypotheses inAgricultural Science
