Abstract

Mathematics is one of the important subjects for students, but many of the students do not understand mathematics subjects, especiaIIy in soIving contextuaI probIems. This articIe aims to describe students' errors in soIving contextuaI probIems based on Newman's anaIysis. This type of research is quaIitative research. The data coIIection method used in this research is the observation method in the form of test resuIts and fieId notes. The resuIts showed that there were severaI types of student errors in soIving contextuaI questions, nameIy errors in reading terms, symboIs, words or important information in questions by 22%. Errors in understanding the questions in the form of not knowing what the question was asked and wrong in capturing the information contained in the questions so that they couId not continue to the next process by 18,5%. Errors in the transformation process in the form of not being abIe to change the probIem into the form of a mathematicaI modeI that is correct and incorrect in using the sign of arithmetic operations in soIving probIems is 13,5%. Errors in process skiIIs in the form of errors in caIcuIating or computing and not continuing the compIetion procedure by 26,5%. Errors in writing the finaI answer in the form of not being abIe to write the finaI answer that was ordered by the question and unabIe to concIude the answer in accordance with the mathematicaI sentence and Iess thorough in concIuding the answer by 16%.

Abstract

Based on the results of daily test scores at SMAN 2 Painan, it was found that students' mathematical problem solving abilities were not optimal. This must be overcome because problem solving ability is one of the goals of mathematics learning. The 7E Learning Cycle learning model is one solution to this problem. The purpose of this study is to compare whether the mathematical problem solving abilities of students studying with the 7E Learning Cycle learning model are better than the mathematical problem solving abilities of students who learn with direct learning models in class XI of SMAN 2 Painan. Based on the test results, there is an increase in the ability of students studying with the 7E Learning Cycle model good than mathematical problem solving abilities of students who learn with direct learning models. It can be concluded that the 7E Learning Cycle model influences students' mathematical problem solving abilities. Keywords–The Abilityof Mathematical^Problem Solving, Direct Learning Model, Learning Cycle 7E Model.
