Batik Sukapura merupakan salah satu identitas bangsa Indonesia yang melambangkan budaya masyarakat Sunda. Batik Sukapura digunakan masyarakat Sunda sebagai pakaian yang formal dan bernilai sakral. Sejumlah penelitian tentang batik telah banyak berkembang, namun lebih kepada pengembangan teknologi membatik. Tujuan penelitian ini membahas tentang teori semiotika yang diterapkan pada Batik Sukapura untuk mencari makna filosofis dari motif-motifnya. Penelitian ini menggunakan metode kualitatif dengan pendekatan etnografi. Peneliti mengobservasi beberapa pengusaha batik senior yang masih bertahan dengan industrinya di daerah Sukaraja Tasikmalaya. Hasil penelitian menunjukkan bahwa batik Sukapura memiliki banyak konsep geometri dan sejumlah keteraturan. Sejarah batik Sukapura dimulai dari para pengrajin batik dari Jawa Tengah yang pindah ke Jawa Barat akibat terjadinya peperangan. Saat ini batik tulis semakin terdistorsi akibat perkembangan jaman yang berpindah ke batik cetak bahkan batik digital-printing. Ciri khas batik Sukapura adalah bermotif alam. Dari sudut pandang semiotika, tanda-tanda dari motif ini bukan sekedar pola dan keteraturan matematis namun memiliki makna dan pesan moral yang sangat sesuai dengan falsafah hidup masyarakat Sunda. Penggabungan kajian semiotika dan matematika ini dianggap mampu memberikan penguatan kepada para siswa dalam memaknai nilai-nilai etnomatematika sebagai upaya mengembalikan status matematika yang saat ini dipandang terpisah dari budaya (culturally-free).Kata kunci: sejarah batik sukapura, semiotika

Higher order thinking skill is a topic which attracts more attention of researchers in education field. Critical thinking belongs to higher order thinking skills. This kind of thinking should be had by everyone. Critical thinking belongs to 21st century skills Solving real world-mathematical problem regularly is assumed as one of ways encouraging one to grow and to enhance his critical thinking. A person who has good critical thinking skill in solving mathematical problems is considered to also think critically well in living his daily life. This study aims to investigate the critical thinking skill of female students consisting of ability in giving argument, drawing conclusion, and evaluating conclusion. A case study was carried out to four female students who were recruited based on their volunteering. Their critical thinking skills were evaluated by using essay test and interview. Participants’ critical thinking in solving mathematical problems is classified into high, medium, or low level. FS-1 and FS-4 are classified as low-level critical thinker. FS-2 and FS-3 are classified as high-level critical thinker.

[English]: This phenomenological study aims to thoroughly investigate the meaning of concepts in algebraic forms developed by students, both in the past learning process and in the didactical design implementation, as well as a teacher's instructional experiences as the basis for preparing a didactical design. Six seventh-grade students and a mathematics teacher participated in the study, comprising three phases: (1) analyzing students’ learning obstacles through a test and teacher’s interview, (2) preparing hypothetical learning trajectory (HLT) and didactical design based on the identification of the obstacles and in-depth interviews with the teacher, and (3) implementing the didactical design. This study revealed that students have a didactical obstacle because the teacher delivers formal definitions of algebraic form concepts followed by examples of problems. It results in epistemological obstacles, as students' understanding of the concepts is limited according to what the teacher explains. Furthermore, an HLT was developed that bridges students' arithmetic knowledge with algebra. The series of tasks were organized referring to the theory of praxeology by taking the daily-life context Let's Save. During the learning process, students use different representations, such as symbols and letters, to demonstrate the variable, reason for using a particular representation, and state the definition of a variable based on their work. The procedure was also applied to the remaining four concepts. Through the tasks, students can actively construct their conceptual understanding of the concepts in the algebraic forms. [Bahasa]: Penelitian fenomenologi ini bertujuan untuk mengkaji secara mendalam pemaknaan siswa terhadap konsep-konsep dalam bentuk aljabar, baik pada proses belajar sebelumnya maupun pada implementasi desain didaktis, serta pengalaman mengajar guru sebagai landasan dalam membuat desain didaktis. Enam siswa kelas 7 dan seorang guru matematika menjadi partisipan pada penelitian ini, yang terdiri dari tiga tahap, yaitu: (1) analisis hambatan belajar siswa melalui uji tes dan wawancara guru, (2) menyiapkan lintasan belajar hipotetik (HLT) siswa dan desain didaktis berdasarkan identifikasi hambatan belajar siswa dan wawancara mendalam dengan guru, dan (3) mengimplementasikan desain didaktis kepada siswa. Hasil penelitian ini menunjukkan bahwa siswa mengalami hambatan didaktis yang disebabkan oleh cara guru mengajar. Guru cenderung memberikan definisi formal pada konsep-konsep bentuk aljabar dilanjutkan dengan contoh-contoh soal. Hal ini mengakibatkan siswa mengalami hambatan yang bersifat epistemologis, dimana pengetahuan siswa terhadap konsep-konsep bentuk aljabar terbatas berdasarkan apa yang dijelaskan oleh guru. Kemudian, dirancang HLT yang menjembatani pengetahuan aritmatika siswa dengan aljabar. Rangkaian tugas disusun berdasarkan teori praxeology dengan mengambil konteks kehidupan sehari-hari bertema Ayo Menabung. Selama proses pembelajaran, siswa menggunakan berbagai macam representasi seperti simbol dan huruf, untuk menunjukkan variabel, mengemukakan alasan dari penggunaan representasi tertentu, dan mengungkapkan definisi variabel sesuai dengan hasil pekerjaannya. Hal ini juga berlaku pada keempat konsep lainnya. Melalui tugas yang diberikan, siswa dapat berpartisipasi aktif dalam membangun pengetahuan tentang konsep-konsep dalam bentuk aljabar.

Mathematics is often become the frightening subjects for students. Mathematics is considered as something which is difficult to solve. One of the elementary schools mathematics materials which is considered difficult is fractions. Not only students who consider fractions as difficult material but also teachers admit it as well. Teachers feel difficult in teaching fractions to students. Basic concept of fractions which is difficult for the student to grasp, would become even more complex if it is delivered in the form of word problem. In solving word problems students do not only need mathematic skills but also language skills. This research is aimed to analyze students learning difficulties in solving fractions word problem. This research is a qualitative research. The method of analysis used in this research is Newman method. The results of the research show that students faced difficulties in solving fractions word problems because (1) it is difficult for the students to understand the question and to translate it into mathematical sentence, (2) it is difficult for the students to determine the operation used in the word problems, (3) students are not accustomed to, thus they forget to write the conclusion/write the conclusion without the unit in every answers.
