摘要:AbstractThis study aim to investigate the effect of educational complemental images on spatial intelligence of second grade guidance boy students. The used training images in this study are formed in four types including imagery puzzles, illustrated maps, educational slides, and complemental images. This study was done in quasi-experimental method and using a standard test of spatial intelligence to measuring the growth level of spatial intelligence in students. Findings showed that, after the analysis of ANOVA and LSD test, there is significant difference between the spatial intelligence of students who use puzzles, maps, slides, and complemental images during learning and students who only use the images of the textbook and the spatial intelligence of experimental groups was superior.
