Analysis of Mathematical Communication Skills to Students Based on Problem-Solving Construction

Abstract

This research aims to systematically analyze students' mathematical communication skills based on the given problem-solving construction from the given math problems. The students involved in this study are class IX SMPN 1 Mangarabombang. The type of research applied is qualitative research with a descriptive approach. The research instruments are Mathematical Ability Test, Mathematical Communication Skills Guidelines, and Interview Guidelines. In this study, triangulation techniques were used to check the validity of the data that had been obtained. Data analysis techniques in this study use model with the following stages: 1. Data Reduction, 2. Data Presentation, and 3. Making Conclusion. The results show that mathematical communication skills can be demonstrated by mathematical modeling, representation of ideas, development of the ability to use mathematical object devices, and connecting algebraic expression to mathematical ideas. To realize this, the researcher understood and mastered mathematical concepts to support solving the given problems. Understanding, in this case, is characterized by indicators not only knowing mathematical concepts but knowing at the time when they are used and how to apply them. Then mastery is to place the mathematical concept in the context of the problem.

The Role of Student Team Heroic Leadership Strategy: Mathematical Communication of Middle-School Students

“…The following instruments were used in this study: (1) a test to assess students' mathematical communication skills; (2) student response questionnaires to elicit student feedback on the implementation of the student team heroic leadership learning strategy; and (3) interviews with several students to elicit information about aspects of the student team heroic leadership learning strategy that are difficult to observe or cannot be observed directly by the researcher during observations. The mathematical communication exam adaptation was developed in accordance with the indicators of mathematical communication skills in problem-solving by (Brenner, 1998;Fitrianti et al, 2018;Nasrullah, 2022;Puspa et al, 2019). The test indicators are presented in Table 1.…”
