Abstract

The purpose of this study is to describe the errors and causes that often occur in solving problems in the material building space beam and cube in terms of mathematical communication. In this study using a type of qualitative descriptive research, with data collection techniques used are tests, and interviews. The subjects of this study were 4th semester students at one of the universities in Bandung. The analysis technique used is an interactive technique which includes data collection, data reduction, data presentation, and conclusion drawing. The mathematical communication indicators used in this research are expressing everyday problems in mathematical languages / symbols, presenting allegations, and drawing conclusions. Errors made by students in solving problems are wrong in symbolizing data that is known and asked, does not calculate prerequisite data, determine formulas, and do not draw conclusions. The cause of the error is due to the assumption that symbolizing the known and asked data is not important, does not focus when working on the problem so that it is not thorough and understands the questions given, and the unfamiliarity to draw conclusions on each problem resolved

Abstract

Tujuan dari penelitian ini untuk mengetahui peningkatan kemampuan penalaran matematis peserta didik setelah memperoleh pembelajaran Group to Group Exchange berbantuan Quizizz. Metode yang digunakan adalah kuasi eksperimen dengan desain The Nonequivalent Pretest-Posttest Control Group Design. Sampel diambil dengan teknik purposive sampling, sehingga diperoleh sampel 2 kelas disalah satu SMK di Bandung Barat. Instrumen yang digunakan yaitu tes kemampuan penalaran matematis. Hasil penelitian dan pengolahan data N-Gain, diperoleh bahwa rata-rata peningkatan kemampuan penalaran matematis peserta didik setelah memperoleh pembelajaran Group to Group Exchange berbantuan Quizizz adalah 0,70 dan rata rata N-Gain  pada pembelajaran konvensional adalah 0,50. Disimpulkan bahwa peningkatan kemampuan penalaran matematis peserta didik yang memperoleh pembelajaran Group to Group Exchange berbantuan Quizizz lebih baik daripada konvensional. The purpose of this study was to determine the increase in students' mathematical reasoning abilities after receiving Group to Group Exchange assisted Quizizz learning. The used method is quasi-experimental design with The Nonequivalent Pretest-Posttest Control Group Design. The sample was taken by using the purposive sampling technique, to obtain a sample of 2 classes in one of the Vocational High Schools in West Bandung. The used instrument is test of mathematical reasoning ability. The results of research and processing of data N-Gain, it was found that the average increase in students' mathematical reasoning abilities after receiving Group to Group Exchange assisted Quizizz learning was 0.70 and the N-Gain average in conventional learning was 0.50. It was concluded that the improvement of students' mathematical reasoning abilities who received Group to Group Exchange assisted Quizizz learning was better than conventional.
