Creativity is part of the demands of industrial revolution 4.0 mathematics learning. Worksheets practically support the cultivation of creative skills, but the existing worksheets made by teachers do not support the development of student's creative abilities. The research aims to design worksheets according to students' intelligence with an assessment as  learning approach. The study uses an explorative, descriptive, evaluative approach to examine, analyze, and evaluate teacher-made student worksheets with an assessment as learning approach to obtain the work process and components of the worksheet design based on adaptive intelligence. The research subjects were students of class V and teachers of grades IV-VI. There were nine students and three teachers involved in the study. Subjects were divided into three groups. Each group consists of three students and one teacher to conduct a dialogue with an assessment as learning approach. The instrument uses an observation sheet and a fill-in sheet. Data analysis used a constructive descriptive approach. The results of the study show the following. First is the convergence of nine multiple intelligences into linguistic, spatial, and logical mathematics. Second, the core content consists of two parts, namely blocks and cubes. Third, adaptive worksheets do not focus on the material but on how to work according to students' creativity. Fourth, the exercise is part of the material learning process, not a separate component. Fifth, the results of the worksheet design are more about the process of making adaptive worksheets than the final product results. Based on these, mathematics teachers can design adaptive worksheets according to established procedures by paying attention to the core material of each material or subject and the dominance of multiple intelligences.

Tulisan ini memperkenalkan metode fuzzy c-means dalam mengklasifikasi konstruk tes. Untuk memverifikasi sifat unidimensional suatu tes biasanya menggunakan analisis faktor sebagai bagian dari statistik parametrik dengan beberapa persyaratan yang ketat sedangkan metode fuzzy c-means termasuk metode heuristik yang tidak memerlukan persyaratan yang ketat. Studi simulasi penelitian ini menggunakan dua metode yakni analisis faktor menggunakan program SPSS dan fuzzy c-means menggunakan program Matlab. Data simulasi menggunakan tipe data dikotomi dan politomi yang dibangkitkan lewat prog-ram Microsoft Office Excel dengan desain 2 kategori, yakni: tiga butir soal dengan banyak peserta tes 10, dan 30 butir soal dengan banyak peserta tes 100. Hasil simulasi menunjukkan bahwa metode fuzzy c-means lebih memberikan gambaran pengelompokan secara deskriptif dan dinamis pada semua desain yang telah dibuat dalam memverifikasi unidimensional pada suatu tes.Kata kunci: fuzzy c-means, analisis faktor, unidimensional_____________________________________________________________ SIMULATION STUDY USING FUZZY C-MEANS FOR CLASIFYING TEST CONSTRUCTIONAbstract This paper introduces the fuzzy c-means method for classifying the test constructs. To verify the unidimensional a test typically uses factor analysis as part of parametric statistics with some strict requirements, while fuzzy c-means methods including method heuristic that do not require strict require-ments. Simulation comparison between the method of factor analysis using SPSS program and fuzzy c-means methods using Matlab. Simulation data using data type dichotomy and politomus generated through Microsoft Office Excel programs each with a number of 3 items using the number of participants 10 tests, while the number of 30 test items using the number as many as 100 participants. The simulation results show that the fuzzy c-means method provides a more descriptive and dyna-mic grouping of all the designs that have been made in verifying the unidimensional as a test.Keywords: fuzzy c-means, factor analysis, unidimensional

According to Item Response Theory, the difficulty level is a characteristic of the test item. The difficulty level of the test items is a characteristic of the test items that are on a scale with the ability level parameter. However, this relationship has not been studied optimally, especially in students' interest and motivation in learning mathematics. This study examines the impact of student involvement in assessing the level of the difficulty test item on interest and motivation in learning mathematics with the approach of assessment as learning. The study involved 176 students from grade VII in SMP and MTs. High-level reasoning test items were adapted from TIMSS test items, while the interest and motivation instruments used a questionnaire. Data analysis used percentages and paired t test. The results showed the difference between before and after estimating the difficulty level test items to students' interest and motivation in learning mathematics. The interest and motivation of students in learning mathematics increased after estimating the level of difficulty of the test items. Therefore, to increase students' interest and motivation in learning mathematics, teachers can involve students in assessing the level of difficulty of the test items using the approach of assessment as learning.

Penelitian ini bertujuan menghasilkan instrumen tes HOTS siswa pada pembelajaran Matematika kelas VI yang valid dan reliabel ,praktis dan efektif serta memiliki karakteristik yang baik. Instrumen tes yang dikembangkan dianalisis validitas internal menggunakan Aiken dan analisis butir soal menggunakan pengukuran RASCH untuk mengetahui tingkat kesulitan soal, tingkat kesesuaian soal dan deteksi adanya bias. Penelitian inidilaksanakan di UPT SD Negeri 12 Bontoramba Kabupaten Jeneponto. Penelitian ini menggunakan desain penelitian pengembangan yang dikemukakan oleh Martin Tessmer, yang terdiri dari empat tahapan. Instrumen tes di telaah oleh 3 ahli, uji coba one to one diikuti oleh 3 orang siswa, small group diikuti oleh 6 orang siswa dan field tes diikuti oleh 28 orang siswa. Pengumpulan data dilakukan menggunakan teknik wawancara, kuisioner, dan pemberian soal tes sehingga data yang dianalisis adalah data kualitatif dan kuantitatif. Kesimpulan dari penelitian ini keefektifan instrumen tes HOTS yang telah dikembangkan dan  menghasilkan prototype III; (d) serta tahap field test (high resistance in revision).
