Abstract

The ability to think creatively is one of the abilities students must possess in learning mathematics. Through this creative thinking ability allows students to solve problems with various solutions. An open-ended problem with the possibility of more than one solution is considered appropriate in measuring students' mathematical creative thinking abilities. Therefore, developed a test instrument that contains open-ended problems to measure students' mathematical creative thinking ability. This test was developed over a period of 6 months consisting of 5 items based on indicators of the ability to think creatively that is fluency, flexibility, originality and elaboration. The purpose of this study is to know (1) the validity of the item, (2) the difficulty index, (3) the discrimination, and (4) the instrument reliability so that these instruments are appropriate to be used to test students' mathematical cretive thinking ability. The population in this study is all students of class VII in State Junior High School 1 Tanjungsiang academic year 2016/2017, even semester. The sample was selected randomly as many as 37 students. Data collection in this research using test method. The result of the research is (1) all valid items with the validity level of 3 items of high question and 2 items are sufficient, (2) four items with the level of difficulty is moderate and one item with high difficult, (3) three items with discrimination is good, poor, sufficient, (4) sufficient category instrument reliability. Based on the results of the trial, it can be concluded that the instrument is worthy used to measure the mathematical creative thinking ability of junior high school seventh grade students. The types of problems used in these tests, indicators, scoring rubrics, and statistical analyzes have been described in this paper.

Keywords: Creative thinking, open-ended problems, validity, the level of difficulty, discrimination power and reliability.
