The Difference

Problem-solving ability is a characteristic of mathematical activities and a major ability in developing mathematical understanding. Mathematical problem-solving ability can be seen from several dimensions, one of which is cognitive style. Cognitive style is a unique way for each individual to acquire, process, store, use the information to respond to tasks or situations, and build knowledge. FD and FI cognitive styles are one type of cognitive style that are categorized by general ways of thinking, solving problems, learning, and dealing with other people so that they have a relationship with problem-solving abilities. The subjects in this study involved 72 students (around the age of 13-14 years), namely 33 students with FD cognitive style and 39 students with FI cognitive style. The problem-solving ability test instrument in this study was a mathematical problem-solving ability test that had been validated by experts and tested for reliability. The cognitive style test instrument is the Group Embedded Figure Test (GEFT) item developed by Witkin. The problem-solving ability of junior high school students with FI cognitive style is better than FD students even though the difference is not much different.

Realistic Mathematics

In general, junior high school students learn mathematics with an inductive pattern. However, the statements in mathematics are obtained through a deductive mindset. Therefore we need a learning approach that can accommodate students' thinking patterns. Mathematics adheres to the law of consistency which causes the structure of material in mathematics to be hierarchically arranged, interrelated, and has characteristics that have implications for determining strategies, approaches and the use of learning media. This article aims to review the theory of the Realistic Mathematics Education Approach (PMR). An approach that can make students involved in building their own concepts and models used through problem solving. The PMR discussion begins with the definition of PMR, the principles and characteristics of PMR, and the contribution of PMR in learning mathematics. Writing this article uses the literature review method which consists of books, journal articles, and other documents related to the topic of discussion. The results of the study found that Realistic Mathematics Education (PMR) is a mathematics learning innovation that is in accordance with the 2013 curriculum.The use of contexts and models, as well as the use of student contributions through discussions to discuss various linkages between mathematics material, makes this approach able to contribute to improving five general mathematical abilities. which includes: the ability to understand mathematics, problem solving, mathematical connections, mathematical communication, and mathematical reasoning.
