NILAI RASIONALISME SISWA PADA MODEL PROBLEM BASED LEARNING MATERI PROGRAM LINEAR DI SMA
Rationalism values is closely related to mathematics because it’s based on reason and knowledge. The results of rationalism values develop students’ skills in terms of reasoning, expressing, and defending their opinions, interpreting data obtained for experiences and attempting to make predictions. Therefore, this study aims to describes student rationalism values in linear program problem based learning. The research subjects were determined purposively, based on the the result of summative assessment, teacher recommendation, based on the diversity of answers, and being willing to be involved in the research. The selected subject was 3 students of class X SMA in Indralaya. The data were collected using test and interview which wre analyzed descriptively. The Problem Based Learning Model can bring out Rationalism Values in Linear Program material. Students can come up with indicators investigate the truth and draw conclusions. The indicators that appear most frequently are investigating the truth. Difficulties often predominantly arise when translating problems into mathematical models and the cause of students experiencing errors in drawing conclusions is due to errors in understanding mathematical concepts in the form of inequality signs where students mistakenly differentiate between the inequalities "less than" and "less than equal to", one of the things The reason for this is because they have not mastered the prerequisite material such as linear inequalities in one variable or two variables
