Investigation of estimation ability of high school students

Boz, Burçak
The purpose of this study was to investigate the high school students' ability on estimation and computational estimation. The study was conducted in Denizli with 153 ninth grade students who enrolled to general, Anatolian and foreign language high schools. The Estimation Ability Test was utilized. The three formats which are number format, answer format and problem format of the test were analyzedby with respect to school types and gender. The design of the present research was one group pretest-posttest design. The hypotheses of the study were tesetd by using analysis of covariance at the significance level 0.05. The results of the study indicated that: 1. There were statistically significant differences among the mean scores of students enrolled to different kinds of high school with respect to estimation ability and computational estimation in favor of Anatolian High School students. 2. There were statistically significant mean differences of students enrolled to diffrent kinds of high school with respect to sub-categories of the estimation ability test in favor of Anatolian High School students. 3. There was no statistically significant mean difference between boys and girls on estimation ability. 4. There was statistically significant mean difference in some sub-categories of the estimation test in favor of boys.
