Development of Mathematical Communication Skill through Worksheets Integrated Problem Based Learning using ADDIE Model

Abstract

Mathematical communication is one of the skills that everyone needs to have to succeed in studying and working, especially in the 21st century era and the industrial revolution 4.0. Mathematical communication skills are very important for students to present arguments in presentations and discussions. These skills can be developed through problem-based learning model. However, student worksheets to support these models have not been extensively created. Therefore, this study aims to develop student worksheets to support problem-based learning models. In student worksheets, mathematical communication skills were integrated into activities. Furthermore, it uses a study and development model including Analysis, Design, Development, Implementation, and Evaluation (ADDIE). The subjects were 50 8th-grade students and 2 mathematics teachers at a Junior High School in Yogyakarta, Indonesia. Here, the teacher is an expert in judging. Collection of data was conducted through observation techniques, interviews, documentation and testing. The result showed that a valid, practical, and effective student worksheets should be able to support the problem-based learning model by integrating students' mathematical communication skills. It can be used by teachers when the teaching and learning process are conducted through a problem-based model. Its substantial contribution is the integration of mathematical communication skills into worksheets. Therefore, students using the worksheets will understand the subject matter and master communication skills simultaneously.

“…This model is often used to develop software and learning materials based on user needs (Jais et al 2022). Because of its flexibility, this model can be modified according to user needs to create the desired innovation (Putri et al 2022). The ADDIE model is used in this study because it can be a systematic and programmed guide for developing effective, dynamic, and supportive learning (Suratnu, 2023).…”
