The Development of Open-Ended Math Questions on Grade V Students of Elementary School

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.

“…Matematika memiliki substansi yang sangat membantu untuk membentuk cara berpikir peserta didik, terutama untuk membangun kemampuan penalaran dalam pemecahan masalah. Surya (2020) mengemukakan bahwa dengan menjawab pertanyaan matematika merupakan cara yang direkomendasikan untuk melatih peserta didik memahami materi matematika dan memperoleh kemampuan matematika yang diharapkan. Pendapat tersebut menjelaskan bahwa matematika merupakan salah satu cabang ilmu pengetahuan yang sangat bermanfaat bagi kehidupan manusia oleh karena itu, guru harus mampu mengembangkan sistem pembelajaran yang aktif, kreatif, dan inovatif untuk membaantu peserta didik belajar matematika.…”
