Abstract

The development of students? creativity in solving problems can be increased by giving open-ended problems which has multiple answers and multiple ways to get sollution. The purpose of this research is to develop the valid, practicable, and efective open-ended problems in circle main topic for junior high school. The type of this research is the Research and Development (R&D) using Tiagarajan?s 4D model without the implementation phase. This research involves three main phases: 1) define, 2) design, and 3) develop. The develop phase is consist of three steps, those are the expert validation, limited test, and field test. This study has been conducted on VIII grade students of a Junior High School in Bengkulu City on second semester of 2012/2013 academic year: 32 students for limited test, and 132 students for field test. Based on the expert validation, limited test, and field test, the result of this development is the the valid, practicable, and efective open-ended problems in circle main topic for Junior High School. From the study, can be conclude that those open-ended problems can be used for developing the junior high school students? creativity
