Publisher : Department of Mathematics Education, Faculty of Mathematics and Natural Sciences, UNY

Penelitian ini bertujuan untuk menghasilkan instrumen pengukur higher order thinking skills (HOTS) matematika siswa kelas X yang valid dan reliabel, dan Untuk mengetahui kemampuan higher order thinking (HOT) matematika siswa kelas X dilihat dari hasil uji coba siswa. Penelitian ini merupakan penelitian pengembangan dengan langkah-langkah meliputi: menyusun spesifikasi tes, menulis soal tes, menelaah soal tes, melakukan uji coba tes, menganalisis butir soal, memperbaiki tes, dan merakit tes. Uji coba instrumen dilakukan di kelas X pada tiga sekolah, yaitu SMAN 4 Kota Yogyakarta sebanyak empat kelas, SMAN 6 Kota Yogyakarta sebanyak dua kelas, dan SMAN 10 Kota Yogyakarta sebanyak dua kelas. Jumlah keseluruhan subjek uji coba sebanyak 169 siswa. Teknik dalam mengumpulkan data pada penelitian pengembangan ini adalah tes tertulis. Sedangkan instrumen pengumpulan datanya berupa soal uraian, pilihan ganda dan jawaban singkat. Instrumen yang terdiri dari 75 butir soal ini, diujicobakan sebanyak 46 butir soal. Instrumen yang diujicobakan dibagi menjadi tiga paket soal. Soal paket A sebanyak 15 butir, soal paket B sebanyak 16 butir, dan soal paket C sebanyak 15 butir. Hasil penelitian menunjukkan bahwa instrumen yang dibuat valid. Hal ini berdasarkan perhitungan yang menggunakan rumus Aiken, bahwa nilai V pada semua butir soal 0,3. Di samping itu, soal paket A dan paket B menghasilkan soal paket yang reliabel, dengan masing-masing nilai Cronbach's Alpha sebesar 0,738 dan 0,658. Sedangkan soal paket C tidak reliabel yang ditunjukkan dengan nilai Cronbach's Alpha sebesar 0,488. Hasil dari uji coba instrumen dapat disimpulkan bahwa kemampuan higher order thinking (HOT) matematika siswa kelas X kurang baik. Hal ini dapat diketahui dari nilai rata-rata hasil uji coba sebesar 26,38 dalam skala 100.Kata Kunci: pengembangan instrumen, higher order thinking skills (HOTS), validitas, reliabilitas. Developing an Instrument to Measure Higher Order Thinking Skills of Mathematics In Class X Senior High School AbstractThis research aims to know an instrument to measure higher order thinking skills (HOTS) of mathematics of class X student which is valid and reliable, and to know the higher order thinking skills (HOTS) of mathematics of class X students seen from the trial test. This research was the development of instruments with steps: preparing test specifications, writing the items, reviewing the items, doing trial tests, analyzing the items, correcting the items, and arranging the items. The instruments trial was done in class X at three schools, that is SMAN 4 of Yogyakarta as many as four classes, SMAN 6 Yogyakarta as many as two classes, and SMAN 10 Yogyakarta as many as two classes. The total number of subjects tested was as many as 169 students. The technique in collecting data on this research is a test, while the data collection instruments in this research are essay, multiple choice and short-answer items. The instrument consists of 75 items, but only 46 items were tested. Instruments tested were divided into three packets. Packet test A totaling 15 items, packet test B totaling 16 items, and packet test C totaling 15 items. The research finding reveals that the instrument is valid. This is based on calculations of Aiken’s formula, that value of V for all items are less than 0.3. Besides it, packet test A and packet test B are reliable, with each value of Cronbach's Alpha are 0.738 and 0.658. But for packet test C is not reliable, because the value of Cronbach's Alpha is 0.488. The results of the test instrument can be concluded that the ability of higher order thinking (HOT) of mathematics of class X student is poor. It can be seen from the average value of the test results of 26.38 in the scale of 100.Keywords: instrument development, higher order thinking skills (HOTS), validity, reliability.

Penelitian ini bertujuan untuk mendeskripsikan perilaku siswa cerdas istimewa saat pembelajaran pengayaan matematika menggunakan kalkulator. Penelitian ini merupakan penelitian deskriptif dengan pendekatan kuantitatif dan kualitatif. Subjek penelitian adalah siswa kelas VIII-A SMP Negeri di Kota Pasuruan yang terdiri dari 33 siswa. Subjek yang dipilih berasal dari kelas unggulan pada sekolah tersebut. Instrumen penelitian berupa lembar observasi dan kuesioner. Analisis data menggunakan analisis deskriptif kuantitatif dan kualitatif. Hasil penelitian mengungkapkan bahwa siswa masih menggunakan perhitungan manual daripada menggunakan kalkulator ketika mengerjakan tes awal. Ketika siswa mengerjakan beberapa soal pada lembar kegiatan peserta didik, siswa antusias untuk memahami petunjuk pengoperasian kalkulator, meskipun beberapa siswa masih mengajukan pertanyaan kepada guru. Kasus lainnya, siswa terlihat kebingungan saat hasil yang muncul di kalkulatornya berbeda dengan hasil teman-temannya, sebagian besar siswa baru mengetahui fungsi lain dari tombol-tombol kalkulator. Berbagai tantangan dan potensi pemanfaatan kalkulator dalam pembelajaran pengayaan matematika didiskusikan dalam artikel ini. The behavior of special intelligent students when learning mathematics enrichment using a calculatorAbstractThis study aimed to describe the behavior of special intelligent students when learning mathematics enrichment using a calculator. This research was descriptive research with quantitative and qualitative approaches. The subjects were eighth-grade students of a public junior high school in Pasuruan City, Indonesia, which consisted of 33 students. The selected subjects came from the superior class at the school. The instruments were observation sheets and questionnaires. Data analysis used quantitative and qualitative descriptive analysis. The study results revealed that students still used manual calculations instead of using a calculator when doing the initial test. When students solved some problems on the worksheet, students were enthusiastic about understanding the instructions for operating the calculator, although some students still asked questions to the teacher. In another case, students looked confused when the results that appeared on their calculators were different from the results of their friends; most of the students just found out about other functions of the calculator buttons. Various challenges and potential use of calculators in mathematics enrichment learning were discussed.

Teachers’ diagnostic practice on students-difficulties is one of the important steps in designing and managing classroom lessons. The purpose of this study was to explore teachers’ perception and practices regarding diagnosing students’ learning difficulties. The participants of the study were 28 Indonesian mathematics teachers of Junior High School. The data was collected through a Focus Group Discussion and a teacher questionnaire. The data were analyzed qualitatively to describe how the teachers perceive learning difficulties and how the teachers diagnosed students’ learning difficulties. The results of the analysis reveal that the teachers do not yet perform an in-depth diagnosis of students’ difficulties in learning mathematics. The teachers only focus on the mathematics topics and non-mathematical issues, instead of on students’ thinking process. The teachers also do not differentiate the diagnosis, evaluation, and prediction test. With regard to the strategies used by the teachers to diagnose students’ difficulties, analyzing students’ responses to tests was the majority. In this respect, observing students’ learning process during classroom activities is rarely done by the teachers in the purpose of diagnosing students’ learning difficulties. The results of the diagnosis are mainly used as the basis for remedial and drill and practices. The results imply that more support is needed for teachers to improve their competences particularly in diagnosing students’ thinking process difficulties when learning mathematics.
