Abstract

The purpose of this study is to describe the ability to represent the mathematical concept of students in solving spatial building problems. The type of research used is qualitative descriptive. Data is collected using tests, interviews, and documentation. Tests and interviews are conducted to learn more about the ability to represent the mathematical concept of students in solving the problem of building a room. The subjects in this study were two people, obtained from 30 students through a test of subject networking. The results of the data analysis showed that the ability to representation of mathematical concepts of students arises when presented mathematical problems, namely visual ability, symbolic ability and verbal ability. Visual capabilities in the form of images are to create geometric building images to explain problems and facilitate their resolution; symbolic ability in the form of mathematical equations or expressions by creating mathematical equations or models of the given representation and problem solving by involving mathematical expressions; verbal ability in the form of written words or text that is to write the interpretation of a representation appropriately and write down the steps of solving mathematical problems

Abstract

Students can think and reason about a math problem if they can understand the math problem. A way of looking at mathematical problems also influences the mindset about the solution to be done. Through a contextual approach, students can practice their thinking skills in solving problems. This study aims to determine the ability of mathematical inductive reasoning with a contextual approach in solving fractional problems. This type of research is descriptive qualitative. The number of subjects in this study was 1 obtained using the Purposive Sampling technique using certain criteria, namely student test results on fractional material. The instruments used are using tests and interviews. Tests are used for the process of determining subjects, and interviews are used to determine inductive reasoning abilities. The interview process used is an unstructured interview and is conducted on subjects, peers, and subject teachers. Data analysis techniques using qualitative analysis consist of data collection, data presentation, and conclusions. The results of data analysis show that subjects in the process of solving problems on fractional material have inductive reasoning abilities in the process of solving problems and meet all indicators of inductive reasoning used in this study, namely observing the pattern of questions given, looking for relationships contained in the questions to facilitate problem solving, and determining the estimation of problem solving and drawing conclusions,  and can predict the pattern of solving the next problem
