Abstract

This research aimed to produce a didactic design of equations and linear inequality one variable through scientific approach to develop ability of mathematical communication of grade VII students of junior high school. This type of research is research and development that follows the steps of Borg and Gall which started from a preliminary study in the form of a need analysis, didactic design organizing, didactic design validation followed by revision, field trials followed by revision, and field test. The field test showed that didactical design which had been produced could be classified as useable by design expert judgment. The results of field trialindicated that ability of mathematical communication in good criterion, saw from the percentage of mastery learning which had been fulfilled. Penelitian ini bertujuan untuk mendapatkan desain didaktis persamaan dan pertidaksamaan linear satu variabel melalui pendekatan saintifik dalam mengembangkan kemampuan komunikasi matematis siswa kelas VII SMP. Jenis penelitian ini adalah penelitian dan pengembangan yang mengikuti langkah-langkah Borg and Gall, yaitu diawali dari studi pendahuluan berupa analisis kebutuhan, penyusunan desain didaktis, validasi desain didaktis dilanjutkan revisi, ujicoba terbatas dilanjutkan revisi, dan uji lapangan dilanjutkan revisi. Hasil uji ahli menunjukkan bahwa desain didaktis yang dihasilkan layak. Hasil ujicoba lapangan menunjukkan bahwa kemampuan komunikasi matematis dalam kriteria baik dilihat persentase ketuntasan belajar telah terpenuhi.Kata kunci : desain didaktis dan kemampuan komunikasi matematis.

Abstract

This qualitative research aimed to describe the student’s critical mathematics discourse in Socrates scientific learning. The subjects of this research were 9 students of VII-D class of MTs Negeri 2 Bandar Lampung in academic year 2018/2019 consists of each 3 students with high, medium, and low mathematical ability. The data of this research were obtained through observation, interview, and documentation. Data analysis were processed through three steps that refered to Miles and Huberman models, which were data reduction, data display, and conclusion drawing. Based on the research, the results were: (1) The number of students who did the critical mahematics discourse was successfully increased by Socrates scientific learning, (2) Student’s critical mathematics discourse through Socrates scientific learning more dominantly showed the indicator of student’s critical thinking skill in interprettation and analysis, (3) Student’s critical mathematics discourse was more likely to occur when the teacher asked Socrates’ questions types of clarifycations and reasons and evidence of investigation, (4) Student’s critical mathematics discourse more dominantly showed when the students did scientific approach, which were associating and communicating.
