Abstract

The aim of the present study was to investigate the effectiveness of using researcher-made multimedia software on fifth-grade students’ science educational achievement in Tarom County in the academic year of 2017-2018. This is an applied quasi-experimental study. The population of the research included all fifth-grade students in Tarom County (723 people) among whom 60 people were selected as the sample of the study; sampling was done using simple random sampling. A teacher-made test was used for data collection. Test reliability was favorable (Cronbach's alpha=0.838 for pretest; Cronbach's alpha=0.856 for posttest). Independent t-test was used for examining the collected data. SPSS software was used for data analysis. The results of the research indicated that the use of the researcher-made multimedia software affects the students’ science learning regarding Bloom's cognitive levels including knowledge but the effect was not significant. It has no effect on the level of ‘synthesis’; it has a positive effect on the levels of ‘comprehension, application, analysis and evaluation’. Generally, the use of the researcher-made educational software affects the students’ educational achievement regarding science
