Abstract
Abstract The purpose of this research is to produce valid, practical and effective open-ended based mathematical questions in measuring the high-level thinking ability of grade V students of elementary schools. The study was conducted at 002 and 008 Public Elementary Schools in Bangkinang. The research was a Design Research, which is another term of development research according to Plomp and Nieveen. The development model used is the Plomp model consisting of three stages; preliminary research, prototyping phase, and assessment phase. Based on the results of the development, there were obtained 8 questions for cube and cuboid material and 8 questions for statistic material. Some characteristics of valid mathematical questions based on open-ended are (1) the questions developed have several possible answers or have various ways of answering, (2) the resulting questions can measure higher-order thinking abilities; analysing, evaluating, and creating (3) the material asked is in accordance with the level of the school, which is grade V of elementary school related to cube and cuboid, and statistics materials, (4) the questions are related to the students’ daily life. The characteristics of practical open-ended mathematical questions are that can be used by teachers as an evaluation tool. This question will also be easily obtained because it will be posted in a blog owned by researchers and fellow students.
