This research is a qualitative research, it amis to describe the students’ difficulties in solving three-dimensional problems on the flat-side material. By using purposive sampling technique, then the subjects in this research were 3 students on grade VIII, that is subject KF, subject KK, subject KO and subject KP. For data collection, the instruments used are diagnostic test and interviews. The results showed that (1) Subject KF having facts difficulty relating to the inability to interpret the final results obtained; identify examples and non-example of the concept and an inability to assert concepts, inability to further identify the subject seen from an inability to answer correctly questions provided. The inability of the subject confirms looks of doubt in giving the reasons selecting and deselecting the image. Subject KK also have difficulty in distinguishing geometrical geometrical prism and pyramid; (3) Subject KO having operating difficulty. This is evident from the subject mistake in conducting the operation. Subject KO wrong in doing operations related to the sequence of operations and how to solve equations using division; and (4) Subject KP having principle difficulty. This is evident from the inability of the subject determines the appropriate formula with the given problem. Subject KP capable of memorizing formulas but can not adjust the formula to the problem.

This research was pre experimental research. The experimental design used was One-Group Pretest-Posttest Design which aims to describe and to know the problem solving ability of students of class VIII 3 was taught by applying the model of Missouri Mathematics Project of grade VIII 3. The population was the students of class VIII and the sample was class VIII 3 consisting of 30 students as an experimental class. Based on the results of research and discussion, students were able to solve mathematical problems based on indicators of mathematical problem solving ability. The result of hypothesis test shows: 1)The mean posttest score of the students meets the determined KKM value that is greater equal to 78. This means that the postest average value is significantly greater than 77.9; 2)The average normalized gain value exceeds the medium category. This means that the average value of the gain normalized significantly more than 0.29; and 3)The posttest score obtained by the students has been completed by classical test based on the proportion test. This means that the classical mastery of students' mathematical problem solving abilities after the applied learning model of the Missouri Mathematics Project is significantly more than 0.849.
