Representasi simbol melibatkan metonymy dan metaphor. Metonymy sebagai rantai penanda, dalam hal ini simbol, sedangkan metaphor sebagai pemaknaan dari penanda (simbol). Metonymy dan metaphor saling terkait dan terlibat dalam sistem penyimbolan saat seseorang menemukan simbol baru dalam proses pembelajaran matematika. Mahasiswa Teknik Sipil banyak menemukan simbol baru dalam perkuliahan Kalkulus II, seperti simbol fungsi dua variabel atau lebih beserta turunannya. Simbol-simbol tersebut tentunya berbeda dengan simbol fungsi satu variabel dan turunannya yang telah dipelajari pada Kalkulus I semester sebelumnya. Penelitian ini bertujuan untuk mendeskripsikan kemampuan mahasiswa Teknik Sipil dalam merepresentasikan simbol sebagai metonymy dan metaphor melalui penyelesaian masalah Turunan Parsial. Penelitian ini merupakan penelitian studi kasus, sebagai salah satu upaya untuk mendeteksi kesulitan mahasiswa dalam belajar Turunan Parsial. Mahasiswa diberi worksheet berisi masalah Turunan Parsial yang difokuskan pada representasi simbol sebagai metonymy dan metaphor. Hasil penyelesaian masalah pada worksheet dianalisis berdasarkan representasi simbol turunan parsial baik dari notasinya maupun makna dari notasi. Hasil yang diperoleh adalah bahwa mahasiswa Teknik Sipil kurang mampu dalam merepresentasikan simbol turunan parsial fungsi f terhadap x maupun y. Mahasiswa mampu menentukan selesaian akhir turunan parsial dengan benar, namun kurang baik dalam penandaan simbol turunan parsial.

An Analysis of Errors on Mathematical Symbol as a Metaphor in Linear Programming Saniyatul Wardah; Dwi Priyo Utomo; Octavina Rizky Utami Putri
Didaktik Matematika Vol 8, No 1 (2021): Jurnal Didaktik Matematika
Publisher : Universitas Syiah Kuala

Symbol sense is crucial in the understanding of mathematical problems comprising various symbols. The misuses of symbols happen due to misinterpretation, which is considered the constraint to learn algebra more comprehensively, including in linear programming. The term ‘metaphor’ is defined as a means to carry over symbol sense, and is used to improve mathematical understanding. This present research was aimed at analyzing errors on mathematical symbol as a metaphor in linear programming. This research was conducted by means of descriptive qualitative design, with a test and interview as the instruments. The test was made essay, and its results were analyzed qualitatively. The test, further, was administered to five eleventh graders selected according to highest rates of errors committed. This research has shown that the students committed a number of errors in some cases, such as representing symbols as variables, representing numbers, and interpreting symbols as relational operators. In addition, errors which the students committed in constructing mathematical models covered defining the final value, representing numbers, applying inequality system, and interpreting symbols as operation counts. This present research has provided some ways for symbol sense, and thus the errors on mathematical symbol as a metaphor could be lessened. Next, this research can be further followed up by reviewing the effectiveness of remedial instruction according to the committed errors on mathematical symbols.

Tujuan penelitian ini untuk mendeskripsikan kesalahan representasi simbolik mahasiswa dalam menyelesaikan permasalahan HOTS. Penelitian merupaka kualitatif deskriptif. Pengumpulan data dilakukan dengan dokumentasi dan tes. Subjek penelitian terdiri dari 9 mahasiswa yang dipilih berdasarkan hasil pengerjaan Lembar Kegiatan Mahasiswa (LKM). Hasil penelitian menunjukkan bahwa kesalahan representasi simbolik yang dilakukan oleh mahasiswa terdiri dari (1) kesalahan penulisan simbol turunan parsial, (2) kesalahan dalam menentukan hasil turunan parsial, (3) kesalahan dalam menentukan nilai fungsi turunan parsial, dan (4) kesalahan dalam memahami perintah soal. Kesalahan-kesalahan representasi simbolik tersebut terjadi karena beberapa faktor yaitu kurangnya pemahaman terhadap simbol – simbol turunan parsial, ketidaktelitian dalam menyelesaikan soal, tidak memperhatikan dan memahami perintah soal dengan baik, tidak teliti dalam menuliskan jawaban akhir, tidak memahami konsep turunan parsial dengan baik, dan tidak memahami konsep dalam menentukan nilai fungsi dengan baik. AbstractThe purpose of this study is to describe the symbolic misrepresentation of students in solving HOTS problems. Research is a qualitative descriptive. Data collection is done by documentation and tests. The research subjects consisted of 9 students selected based on the results of the Student Activity Sheet (LKM). The results showed that the symbolic error made by students consisted of (1) writing errors of partial derivative symbols, (2) errors in determining the results of partial derivatives, (3) errors in determining the value of partial derivative functions, and (4) errors in understanding command matter. The errors of symbolic representation occur due to several factors, namely the lack of understanding of partial derivative symbols, inaccuracy in solving problems, not paying attention and understanding the order of questions properly, not careful in writing the final answer, not understanding the concept of partial derivatives well, and do not understand the concept of determining the value of a function properly.
