Implementation of Accelerated Learning to Improve Mathematics Communication Ability

Abstract

The four skills needed in the 21st century are often abbreviated as 4Cs, including communication skills. This research is an attempt to determine students' mathematical communication skills and student responses in learning mathematics. The purpose of this study was to determine the significant improvement in communication skills and to determine student responses to the implementation of accelerated learning. This research uses Quasi Experimental Design with Non-equivalent Control Group Design. Pretest and Posttest in the form of quantitative data in the form of description questions and non-test (questionnaire) in the form of qualitative data. The research was carried out at SMPN 4 Purwadadi with the research population in the odd semester of the 2021/2022 academic year. Sampling using purposive sampling method. The instruments used are test and non-test instruments. The test instrument for students' mathematical communication skills is in the form of description questions and non-test in the form of student response questionnaires. The results of the study by using inferential statistics with a significance level of 5% showed that there was a significant difference regarding the improvement of students' mathematical communication skills and the good response of students to the use of accelerated learning. Keywords: accelerated learning, mathematical communication, junior high school student. Abstrak: Empat kemampuan yang diperlukan di abad 21 sering disingkat dengan 4Cs diantaranya kemampuan komunikasi. Penelitian ini sebagai upaya untuk mengetahui kemampuan komunikasi matematis siswa dan respon siswa dalam pembelajaran matematika. Tujuan penelitian ini untuk mengetahui peningkatan signifikan kemampuan komunikasi serta untuk mengetahui respon siswa terhadap penerapan accelerated learning. Penelitian menggunakan Quasi Eksperimental Design dengan Nonequivalent Control Group Design. Pretest dan Posttest berupa data kuantitatif yang berupa soal uraian dan non tes (angket) berupa data kualitatif. Penelitian dilaksanakan di SMPN 4 Purwadadi dengan populasi penelitiannya adalah semester ganjil tahun ajaran 2021/2022. Pengambilan sampel menggunakan metode purposive sampling. Instrumen yang digunakan berupa instrumen tes dan non tes. Instrumen tes kemampuan komunikasi matematis siswa berupa soal uraian dan non tes berupa angket respon siswa. Hasil penelitian Dengan menggunakan statistik inferensial dengan taraf signifikansi 5% menunjukan terdapat perbedaan yang signifikan mengenai peningkatan kemampuan komunikasi matematis siswa dan bagusnya respon siswa terhadap penggunaan accelerated learning. Kata kunci: accelerated learning, komunikasi matematis, siswa SMP. DOI: http://dx.doi.org/10.23960/jpmipa/v23i4.pp1409-1422
