Abstract: The aim of this study was to describe the thought processes of students in constructing the concept of function composition. The subjects were students of the 2nd half of the course Basic Mathematics II. There are 9 students who were asked to complete the one-time function composition written and simultaneously saying out loud what they think. Furthermore, six students have been selected as subjects. Selection of subject considers their communication skills. From this research, it is found three types of the description of thought processes of students, namely: construction complete thinking structure type, construction complete pseudo-thinking structure type, and incomplete structure type thinking.Key Words: thinking, constructing the concept, function, composition functionAbstrak: Tujuan penelitian ini adalah untuk mendeskripsikan proses berpikir mahasiswa dalam mengon-struksi konsep komposisi fungsi. Subjek penelitian ini adalah mahasiswa semester 2 matakuliah Matemati-ka Dasar II. Sembilan mahasiswa diminta menyelesaikan masalah komposisi fungsi secara tertulis dan sekaligus mengucapkan dengan keras apa yang dipikirkan. Selanjutnya 6 mahasiswa dipilih sebagai subjek. Pemilihan subjek mempertimbangkan kemampuan berkomunikasi mereka. Dari penelitian ini di-temukan 3 tipe deskripsi proses berpikir mahasiswa, yaitu tipe struktur berpikir konstruksi lengkap, tipe struktur berpikir konstruksi lengkap semu, dan tipe struktur berpikir tidak lengkap.Kata kunci: proses berpikir, mengonstruksi konsep, fungsi, komposisi fungsi

Abstract: This research is a case study that explores the error in concept construction of undergraduate students’ with very negative mathematical identity. The construction was examined through the APOS theory. The student participating in the study was a student in the accounting department. Results showed that the student with very negative mathematical identity did not think much when choosing the most suitable measure of central tendency for a particular data. The student did not take into account the existence of outlier and mode, how the mean involves every data element, and whether the data distribution was normal or not. Abstrak: Penelitian ini merupakan studi kasus yang mengeksplor kesalahan konstruksi konsep mahasiswa dengan identitas matematis yang sangat negatif. Konstruksi konsep diteliti menggunakan kerangka APOS. Mahasiswa yang berpartisipasi dalam penelitian ini merupakan mahasiswa pada jurusan akuntansi. Hasil penelitian menunjukkan bahwa mahasiswa dengan identitas matematis yang sangat rendah tidak berpikir banyak ketika memilih ukuran pemusatan yang sesuai untuk data yang diberikan. Subjek tidak mempertimbangkan eksistensi modus dan outlier, bagaimana mean melibatkan semua elemen data, dan apakah datanya berdistribusi normal atau tidak.

Semantic is associated with the relationship between symbol, reference, and the problem’s context involved in the problem-solving process which also involves reasoning and decision-making. Hence, this study describes the characteristics of students’ semantic reasoning to solve the double discounts problem. 51 high school students in Sidoarjo participated in this qualitative study. The data were collected through 15-20 minutes problem-solving tests. The students' answers were grouped into correct and wrong answers. The correct answers were then regrouped once more based on the strategies used by the students to answer the test and to identify their semantic reasoning characteristics. The data were analyzed by reducing, classifying the think-aloud and observing. Then the similarity of characteristics of students' semantic reasoning when solving the double discount problem was identified. To test the accuracy of the data, triangulation method was used. This semantic reasoning was identified by (1) giving the problem situation, (2) stating the keywords and their meaning, (3) stating the relationship, (4) transforming it into a mathematics statement, (5) calculating based on their strategies, (6) decision making, and (7) completing the answer interpretation. This study contributes to developing basic knowledge in interpreting each process of solving ill-structured problems until finding a solution.

The purpose of the study describes the rises of cognitive load of students in learning geometry. The study used a qualitative approach. The results showed that the intrinsic cognitive load is derived from the number of elements of interactivity of position, distance, and angles between points, lines, and areas, congruency of triangles, algebraic and fractional operations. Intrinsic cognitive load comes from the complexity of the learning material that constitutes visualizing, performing algebraic operations, determining congruency triangle, and the angle of difficulties. Extraneous cognitive load that arise due to the way the teacher in explaining too fast and disturbance of some of friends who are crowded / noisy. Germane cognitive load that arises due to the use of Cabri 3D in learning and giving variable exampleTujuan penelitian mendeskripsikan munculnya beban kognitif siswa dalam pembelajaran materi geometri. Penelitian menggunakan pendekatan kualitatif. Hasil penelitian menunjukkan bahwa beban kognitif intrinsic disebabkan oleh jumlah elemen interaktivitas yaitu kedudukan, jarak, dan sudut antara titik, garis, dan bidang, kesebangunan segitiga, operasi aljabar, dan operasi pecahan. Beban kognitif intrinsic disebabkan oleh kompleksitas materi, yaitu kesulitan membayangkan, kesulitan melakukan operasi aljabar, kesulitan menentukan kesebangunan segitiga, dan kesulitan menentukan besar sudut. Beban kognitif extraneous disebabkan oleh cara guru dalam menjelaskan terlalu cepat dan gangguan dari sebagian teman yang ramai/gaduh. Beban kognitif germane disebabkan oleh penggunaan Cabri 3D dalam pembelajaran dan pemberian latihan soal.
