Analysis of mathematical communication skills in problem solving linear programs on online learning reviewed from impulsive and reflective cognitive styles

Abstract

Mathematical communication ability is a very important ability in learning mathematics. Through mathematical communication, students can explore and connect ideas, ideas, and solutions they get. The ideas, ideas, and solutions obtained are then transformed in the form of mathematical models. One of the subjects that requires the ability to convert story language into mathematical language or mathematical models is linear programming. Mathematical models in linear programming consist of linear inequalities that have many solutions. In solving math problems each student has their own cognitive style. Cognitive styles Impulsive and reflective describe the tendency of students to show sooner or later when responding to a problem situation, this cognitive style allows students to analyze differences in solving a mathematical problem. The pandemic Covid-19 that hit almost all countries in the world including Indonesia has an impact on teaching and learning activities, so it must be online. Several obstacles can arise in this online learning process so that students must find solutions to the obstacles they face. Therefore, the description of this conceptual article review aims to describe students' mathematical communication skills in solving linear programming problems in online learning in terms of cognitive styles impulsive and reflective. © 2022 Author(s).
