The purpose of this research is to examine the effects of problem posing intervention on 8th grade students’ mathematics achievement and attitudes toward mathematics. Word problems were used in the research as a tool to observe the differences between experimental and control groups. We analyzed the effects of problem posing instruction by specially designed tests on pre and post activities. Meanwhile we sought student responses through individual meetings.This study has been conducted with 8th grade students at a Kazakh High School for gifted students during the second semester of 2010-2011 academic years. There were 54 students in total that were divided into two groups. One of the groups was experimental and the other was control group. There was equal number of students in each group with a number of 27. The research took two months in the same school.The research used a mixed methods design with quantitative and qualitative components. Data from quantitative component that was pre and post test which were analyzed by using SPSS computer package. Qualitative design included data through which students were compared from pre to post intervention opinions. We used the Mathematics Achievement Test in order to measure the students’ mathematics academic achievement. In order to measure students’ attitudes toward mathematics, we used Mathematics Attitude Scale .The reliability of the tests were measured by special techniques and the value of Cronbach's Alpha constant was calculated as 0.83 for achievement test and 0.90 for attitude scale. During the problem posing instruction with experimental group students we used the activities that were specially designed word problems in the light of problem posing stages. Traditional educational methods were used in the control group. In addition, some questions were prepared for the students who got extreme scores from the activities. At the end of the research, data was evaluated by using paired sample t-test and the analyses of interview with students were conducted by using the descriptive methods.
