Özet:The purposes of the study were to investigate the effects of visual treatment on students’ opinion in terms of thinking process and students’ opinion in terms of feelings in the spatial ability activities; to investigate the effects of visual treatment on student’s spatial ability, spatial visualization and spatial orientation The study was conducted in Ankara with 21 sixth-grade elementary school students. One group pretest-posttest design was used. Two measuring instruments were utilized: Spatial Ability Test and Spatial Problem Attitude Scale. Spatial Ability Test, which was developed by Ekstrom, consists of paper folding and surface development tests measuring the spatial visualization ability and card rotation together with cube comparison tests measuring the spatial orientation ability. The tests were translated into Turkish by Delialioglu, (1996). Spatial Problem Attitude Scale was developed by researcher. The study employed both quantitative and qualitative research using a mixed method design. The researcher conducted 9 interviews with nine 6th grade students from the same class. The students were asked their opinion about the visual treatment in terms of thinking process and feelings in the spatial ability activities. Additionally, the class was observed during their activity time that continued 10 weeks and five hours per week.In order to analyze the obtained data, Friedman and Wilcoxon tests as well as one-way repeated measures Analysis of Variance were used. To analyze data obtained from interviews, the phenomenographic method was used. The results of the study indicated that there was a statistically significant change in students’ spatial ability, spatial orientation and spatial visualization scores across three time periods (pre treatment, post treatment and retention). All three scores were significantly different from each other. Test scores were significantly higher immediately after the visual treatment than those before the treatment. The test scores one month later were significantly lower than those immediately after the treatment, but significantly higher than the scores before the treatment. The findings suggest that visual treatment has positive effects on students’ spatial cognitive process and their attitudes toward spatial ability problems. Selection of the appropriate visual treatment should be based on students’ needs and their cognitive development level for providing better learning environment
