Abstract

Mathematical problem-solving ability is an important skill that students need to have to solve various problems logically and systematically. However, the mathematical problem-solving ability of fourth-grade students on plane geometry material is still relatively low. The purpose of this study is to improve students' mathematical problem-solving ability through the application of the Think Pair Share (TPS) learning model assisted by Quizizz. This study uses Classroom Action Research (CAR) which is implemented in two cycles through the stages of planning, implementation, observation, and reflection. The subjects of this study were 22 fourth-grade students at one of the Public Elementary Schools in Central Aceh Regency. Data collection techniques were carried out through tests to measure students' abilities on plane geometry material, as well as observation and interviews to obtain information about the learning process. The results of the study showed that the application of the Think Pair Share (TPS) model assisted by Quizizz was able to improve students' abilities in solving mathematical problems. Classical learning completeness increased from 31.81% in cycle I to 86.36% in cycle II. Teacher activity showed a percentage of 78.32% in cycle I and increased to 88.32% in cycle II. Meanwhile, student activity showed a percentage of 76.10% in cycle I and increased to 86.10% in cycle II. The research findings indicate that the implementation of the TPS model assisted by Quizizz is effective in improving the mathematical problem-solving skills of fourth-grade elementary school students on plane geometry.

Abstract

Mathematical representation skills are one of the essential competencies that elementary school students need to have. However, there are still many students who experience learning obstacles in connecting mathematical concepts with the context of daily life. This is due to the abstract nature of mathematics, making it difficult for students to convey mathematical ideas in a representative manner. This research aims to improve students' mathematical representation skills through project-based learning by utilizing inorganic waste as a learning medium. This study uses a pre-experimental method with a one group pretest-posttest design. The research activity was carried out at UPTD SD Negeri 18 Juli by involving 25 grade III students as research subjects. Data collection is carried out through observation, initial tests, and final tests, while discussion activities are facilitated through Student Worksheets (LKS). The research instrument is in the form of description questions that contain indicators of mathematical representation ability. The results showed a significant increase in the three aspects of mathematical representation, namely the visual (from a score of 4.5 to 7.6), the symbolic (from 4.3 to 8.0), and the verbal (from 5.0 to 8.3). Thus, it can be concluded that project-based learning by utilizing inorganic waste is effective in improving the mathematical representation skills of elementary school students. In addition, this approach also fosters environmental awareness and students' creativity in recycling waste into products with useful value.
