Penelitian ini bertujuan untuk mendeskripsikan proses terbentuknya representasi skematis murni dan representasi skematis campuran yang diciptakan oleh siswa selama menyelesaikan word problem. Jenis penelitian yang digunakan adalah kualitatif yang bersifat deskriprif. Dalam penelitian ini melibatkan 45 siswa kelas 8. Sedangkan untuk memilih subjek tidak dipilih secara acak, namun dipilih berdasarkan kemampuan siswa dalam menciptkan representasi skematik. Pengumpulan data dilakukan dengan meminta siswa untuk menyelesaikan Tugas Pemecahan Masalah secara think aload, yaitu siswa diminta untuk menyuarakan apa yang dipikirkannya. Selain itu siswa juga menuangkan pikirannya mengunakan kertas dan pensil. Hasil penelitian ini menunjukkan bahwa proses representasi skematis murni diciptakan siswa dengan membuat gambar skema berupa garis besar dari masalah dan dilengkapi dengan beberapa keterangan pokok yang ada dalam masalah. Sedangkan proses representasi skematis campuran diciptakan siswa dengan membuat gambar skema yang dilengkapi dengan keterangan-keterangan dan gambar nyata yang sesuai dengan situasi dalam masalah. Kedua jenis representasi skematis ini sangat efektif dalam membantu siswa dalam menyelesaikan word problem. Kata kunci: representasi skematis, representasi skematis murni, representasi skematis campuran. This study aims to describe the process of formation of pure schematic representation and mixed schematic representation created by students during solving word problem. The type of research used is descriptive qualitative. In this study involving 45 students 8th grade. While to select the subject not selected at random, but selected based on the ability of students in creating schematic representation. The data collection is done by asking the students to solve the Problem-solving Tasks of think a load, ie the students are asked to voice what they think. In addition students also pour their minds using paper and pencil. The results of this study indicate that the process of pure schematic representation is created by creating schematic drawings in the form of an outline of the problem and supplemented with some basic information that exists in the problem. While the process of mixed schematic representation was created by the students by drawing schematic drawings with explanations and real images that fit the situation in the problem. Both types of schematic representation is very effective in assisting students in solving word problem. Keywords: representation, schematic representation, pure schematic, mixed schematic.

The aim of this study is to describe students’ thinking process in creating schematic representation. A describtive qualitative research is used in this paper along with case study approach. The examined case is students’ thinking process in creating schematic representation in solving word problem. The subjects are Junior High School students at grade VIII. Data collection were done by think aloud technique and interview. The result show that students’ thinking process in creating schematic representation is retrieved from processing theory started by taking the problem into account. Students read the problem based on its intonation with stress in each sentence. Then, students create a scheme and link all information they understand about. This scheme later is drawn into triangle form. By creating the scheme, students are able to comprehend the questions and problems proper. Students connect problems faced by theirself with the concept of Phytagoras stored in long-term memory. The students' understanding of the Phytagoras Theorem concept is well preserved so that students can solve the problem appropriately.

Schematic representation is very important for students to solve problems in solving word problems. There are two types of schematic representation namely pure schematic representation and mixed schematic representation. The process of forming a pure schematic representation tends to be more concise than the process of forming a mixed schematic representation. So it is necessary to investigate in more detail and in-depth which is more effective between pure schematic representation or mixed schematic representation in helping students to solve word problems. This study aims to determine the effectiveness of pure schematic representation and mixed schematic representation in solving word problems. The effectiveness mentioned in this study is the accuracy and precision of the schematic representation formed by the students when solving word problems. This study uses a qualitative approach involving students from grade IX in Metro City, Lampung, Inonesia as research subjects. The students involved in this study were 60 students. Of the 60 students, two were selected as research subjects representing pure schematic representation and mixed schematic representation. Both subjects were chosen considering the possibility of forming a schematic representation and having good communication skills. The results of this study indicate that students who form pure schematic representation present information and schematic drawings formed in a more concise, precise and accurate manner. While students who form a mixed schematic representation by presenting less structured information, the schematic drawings formed are longer. So it can be concluded that a pure schematic representation is more effective than a mixed schematic representation for solving word problems.Keywords: Representations; mixed schematic representations; pure schematic representations; word problem. AbstrakRepresentasi skematis sangat penting bagi siswa untuk mengurai masalah dalam menyelesaikan word problem. Terdapat dua jenis representasi skematis yaitu representasi skematis murni dan representasi skematis campuran. Proses terbentuknya representasi skematis murni cenderung lebih ringkas (pendek) dibandingkan dengan proses terbentuknya representasi skematis campuran. Maka perlu diselidiki lebih detail dan mendalam manakah yang lebih efektif antara representasi skematis murni atau representasi skematis campuran dalam membantu siswa selama menyelesaikan word problem. Penelitian ini bertujuan untuk mengetahui efektivitas antara representasi skematis murni dan representasi skematis campuran dalam pemecahan word problem. Efektivitas yang dimaksud dalam penelitian ini adalah ketepatan dan keakuratan representasi skematis yang dibentuk siswa selama menyelesaikan word problem. Penelitian ini menggunakan pendekatan kualitiatif yang melibatkan siswa kelas IX di Kota Metro, Lampung, Indonesia sebagai subjek penelitian. Siswa yang terlibat dalam penelitian ini berjumlah 60 siswa. Dari 60 siswa dipilih dua siswa sebagai subjek penelitian yang mewakili representasi skematis murni dan representasi skematis campuran. Dua subjek tersebut dipilih melalui pertimbangan mampu membentuk representasi skematis dengan baik, dan memiliki kemampuan komunikasi yang baik. Sebuah tes diberikan untuk mengetahui kemampuan siswa dalam membentuk representasi skematis. Hasil pekerjaan siswa yang terkumpul dianalisis dan digunakan sebagai bahan dalam wawancara untuk menggali informasi bagaimana siswa membentuk representasi skematis. Hasil penelitian ini menunjukkan bahwa siswa yang membentuk representasi skematis murni menyajikan informasi-informasi dan gambar skema yang dibentuk lebih ringkas, tepat dan akurat. Sedangkan siswa yang membentuk reprsentasi skematis campuran dalam menyajikan informasi-informasi kurang terstruktur, dan gambar skema yang dibentuk lebih panjang. Sehingga dapat disimpulkan bahwa representasi skematis murni lebih efektif daripada representasi skematis campuran selama menyelesaikan word problem.Kata kunci: Representasi; representasi skematis campuran; representasi skematis murni; word problem.

Penelitian ini bertujuan untuk mendeskripsikan proses translasi representasi siswa dalam menyelesaikan masalah matematika berorientasi pada high order thinking skills (HOTS). Penelitian ini merupakan penelitian kualitatif. Subjek penelitian ini adalah 26 siswa kelas XI di Sekolah Menengah Pertama Negeri 4 Metro. Teknik pengumpulan data dilakukan melalui tes dan wawancara. Siswa menyelesaikan tes sambil mengungkapkan secara lisan apa yang mereka pikirkan (think aloud), kemudian dilakukan wawancara terkait dengan hasil pekerjaan siswa. Hasil penelitian menunjukkan bahwa siswa dalam menyelesaikan masalah matematika berorientasi pada HOTS dilakukan melalui dua proses translasi yaitu translasi representasi verbal ke grafik (gambar) kemudian ke simbolik. Proses translasi representasi tersebut dilakukan melalui tahap unpacking the source, preliminary coordination, constructing the target, dan determining equivalence. Hasil penelitian ini diharapkan dapat digunakan guru sebagai bahan pertimbangan untuk menyusun desain pembelajaran yang tepat khususnya pada soal pembelajaran yang mendorong siswa melakukan HOTS. Sehingga guru dapat mengoptimalkan berpikir siswa dan meminimalkan kesulitan siswa dalam proses translasi representasi. Penelitian selanjutnya dapat memeriksa lebih mendalam karakteristik tiap tahapan translasi representasi. This study aims to describe the process of translating students' representations in solving mathematical problems oriented to HOTS. This research is a qualitative research. The subjects of this study were students of class XI at Metro 4 Public Middle School. Data collection techniques are done through tests and interviews. Students complete the test while verbally expressing what they think (think aloud). Then the researchers conducted interviews related to the results of student work. The results showed that students in solving mathematical problems oriented to HOTS were carried out through two translation processes, namely the translation of verbal representations into graphs (pictures) then to symbolic. The translation translation process is carried out through the stages of unpacking the source, preliminary coordination, constructing the target, and determining equivalence. The results of this study are expected to be used by teachers as consideration for developing appropriate learning designs, especially on learning problems that encourage students to do HOTS. So the teacher can optimize student thinking and minimize student difficulties in the process of translational representation. Future studies can examine in more depth the characteristics of each translation translation stage.
