Abstract
This study aims to produce a form of algebra word problems PMRI valid and practical, as well as having a potential effect was to determine the ability of mathematical problem solving of the students class VII. The development research carried out in two stages preliminary and formative evaluation. The research subjects are students of class VII 8 SMP Negeri 1 Palembang. Data collection techniques in this study is the walk through to determine the validity of the story about, the documentation to determine the practicality of word problems and tests to determine the potential effects of a math problem-solving abilities of the students. Valid found that about stories that have been developed have appropriate content, and language constructs. Practical results obtained from tests on small stages where the group is about the story that has been developed is easy to use by users and easy to use by students. The results of the field test showed that about stories that have been developed have a potential effect on the ability of mathematical problem solving of the students class VII, namely the emergence of diversity measures and mathematical problem-solving strategies on students' answers. This is consistent with the results of the field test found 47,8 % included in the excellent category and 30,4 % included in both categories
