Abstract

Problem solving ability is one of the mathematical abilities that are the focus in learning mathematics. There are several factors that cause students' low mathematical problem solving abilities. One of them is the unavailability of learning tools to facilitate students in improving their mathematical problem solving skills. One of the efforts made to improve problem solving skills is to develop guided inquiry-based mathematics learning tools. This study aims to produce valid, practical, and effective learning tools. This type of research is development research with the Plomp model which consists of preliminary stages in the form of needs analysis, curriculum analysis, concept analysis, and student analysis. In the development or prototyping stage, product development is carried out, then formative evaluation is carried out to determine the validity and practicality of the product. The assessment stage is carried out by testing the practicality and effectiveness.

Abstract

This study aims to describe the mistake of students in solving mathematical questions in social arithmetic material based on the taxonomy of SOLO. The errors studied were based on the types of Subanji and Mulyoto errors  which included conceptual errors, errors using data, errors in interpretation of language, technical errors, and errors in conclusions. Preparation of test questions and response levels of students based on the level of the problem on the SOLO taxonomy. This research is a descriptive study with ten research subjects in class VII.1 of SMPN 22 Padang. Details of subject taking were three subjects with high mathematical abilities, four subjects with moderate mathematical abilities, and three subjects with low mathematical abilities. The results obtained by the subject tend to do (a) conceptual errors including errors in using formulas, errors in understanding the intentions of statements in the questions, errors in determining the right steps to solve the problem, (b) errors using data include not using data should be used in solving problems, (c) errors in interpretation of language include errors in writing information on the question, (d) technical errors involving calculation errors, (e) errors in conclusions include concluding an invalid statement with logical reasoning. The causes of these errors are not skilled in using formulas, not through, and habits of students who do not repeat the lesson.Keywords - Error Analysis, Subanji and Mulyoto Error Types, SOLO Taxonomy
