Abstract

Often students have difficulty learning mathematics from elementary to college level. Student’s Learning difficulties in mathematics must be addressed soon because it will affect the students' mathematical thinking ability. This study aims to develop the tests that can diagnose which part of student’s learning difficulties, especially on the building curved side space. The development of tests is based on revived Bloom's cognitive rate of taxonomy that is remembering, understanding, applying, analyzing, evaluating and creating. This study development uses the Plomp development model through three stages: 1) preliminary research, 2) prototyping phase, and 3) assessment phase. Results from the development of diagnostic test instruments meet valid, reliable, and practical. Thus a diagnostic test developed could be used as an alternative in knowing the part of student difficulties.

Abstract

UMKM (micro and middle entrepreneurship) plays an important role in advancing the economy of Sumberkerto villagers. In addition, UMKM is an alternative employment opportunity as well for people whose economically are quite adequate. Because the major population working as traditional farmers, agricultural products are not enough to meet their daily needs, villagers alternate the income by working outside. The potential of agricultural products and human resources can still be optimized with the presence of UMKM, encouraging students of Sumberkerto Group 2 Community Service Program to help overcome the above problems with training activities in making corn into ice cream. The targets of the community service activities are Sumberkerto village residents, in Pagak District of Malang Regency. The method of approach is carried out by field surveys, interview with local residents for planning and training programs in making corn ice cream. The products manufactured besides corn ice cream are UMKM training and bazaar at IAI Al-Qolam and the sustainability methods of training on corn ice cream product for Sumberkerto villagers.

Abstract

Trigonometri merupakan salah satu mata kuliah yang wajib ditempuh oleh mahasiswa Tadris Matematika Semester II. Salah satu materi yang dianggap sulit dalam mata kuliah ini adalah pembuktian identitas trigonometri. Penelitian ini dilatarbelakangi adanya kesalahan mahasiswa dalam pembuktian identitas trigonometri. Tujuan penelitian ini untuk mendeskripsikan kesalahan mahasiswa dalam pembuktian identitas trigonometri berdasarkan model Newman dan beberapa faktor penyebabnya. Penelitian ini termasuk penelitian deskriptif kualitatif. Subjek penelitian yakni dua mahasiswa Tadris Matematika. Pengumpulan data dilakukan melalui tes dan wawancara. Hasil penelitian ini diperoleh bahwa terdapat perbedaan kesalahan yang dilakukan yakni subjek FR melakukan 4 kesalahan yaitu kesalahan memahami, transformasi, proses perhitungan dan penulisan jawaban pada soal pertama. Sedangkan subjek IN melakukan 4 kesalahan pada soal kedua yaitu kesalahan pemahaman, transformasi, proses perhitungan dan penulisan jawaban. Kemudian subjek IN melakukan 2 kesalahan pada soal ketiga yaitu kesalahan pemahaman dan proses perhitungan. Kesalahan yang sering dilakukan adalah kesalahan proses perhitungan, akan tetapi kedua subjek tidak melakukan kesalahan membaca. Beberapa penyebab kesalahan terjadi yakni tidak mengetahui strategi atau identitas trigonometri yang sesuai untuk digunakan dalam membuktikan identitas trigonometri, prosedur penyelesaian yang dilakukan kurang lengkap, kurang kreatifnya dalam manipulasi aljabar, dan kurang terampilnya dalam pengoperasian dan perhitungan yang menyebabkan hasil akhirnya menjadi kurang tepat. Trigonometry is one of the subjects that must be taken by second-semester Mathematics Tadris students. One of the materials that are considered difficult in this course is proving trigonometric identities. This research is motivated by the existence of student errors in proving trigonometric identities. The purpose of this study was to describe the mistakes of students in proving their trigonometric identities based on the Newman model and some of the factors causing them. This research belonged to a qualitative descriptive study. The research subjects were two Mathematics Tadris students. Data collection was carried out through tests and interviews. The results of this study showed that the mistakes made were the FR subject made 4 errors in understanding, transformation, calculation process, and answers to the first question. While the subject made 4 mistakes in the second problem, the errors, transformation, calculation process, and answer answers. Then, the IN subject made 2 mistakes in the third question, namely the misunderstanding and the calculation process. Mistakes that are often made were errors in the calculation process, but the two subjects did not make reading errors. Some of the causes of errors occur such as, namely not knowing the strategy or trigonometric identity that is suitable to be used in proving trigonometric identities, incomplete completion procedures, lack of creativity in algebraic manipulation, and lack of skill in operations and calculations which cause the final result to be less precise.
