DEVELOPMENT OF A TEST INSTRUMENT TO MEASURE PROBLEM SOLVING ABILITY ON NUMBER OPERATION MATERIAL

Abstract

The main purpose of this research is to develop a problem-solving ability test on number operation material. The type of research used is Research and Development (R&D) research or development research with the Tessmer development model which consists of four stages, namely: preliminary stage, self evaluation stage, prototyping stage (expert review, one-to-one, and small group), field test stage which was carried out in class IV SDN 196 Polewali. The data collection instruments used were validation sheets, student response questionnaires, and test instruments. The data obtained were then analyzed using data analysis of validity, reliability, difficulty level, differentiability and problem-solving ability results. Based on the results of the validator's assessment, the test instrument developed meets the valid criteria. The reliability test results obtained are very high, the level of difficulty of the instrument is in the medium category and the distinguishing power of the test instrument is in the good category. The results of the analysis of students' problem-solving ability are in the good category. The implications of this research are to familiarize students with problem solving problems, enrich learning variations, as a consideration for further study of mathematics learning problems in schools.
