Abstract

This research was conducted to analyze the test instruments used to measure the ability of students in actuarial mathematics courses in mathematics department, State University of Malang. Participants in this course consist of 40 students. The form of questions given were multiple choice questions totaling 50 items related to the premium calculation material on life insurance. The Rasch model is used to get fit items. This analysis is carried out with the help of Winsteps software. From the Winsteps program output, 25 items were obtained fit to the Rasch model with an average MNSQ Outfit score for person and item 0.98 and 0.98, respectively. While the Outfit ZSTD value for person and item are 0 and -0.01 respectively. While the reliability of the instrument stated in alpha cronbach is 0.85

Abstract

One of the crucial things in the insurance business is determining the amount of IBNR claim reserves. The amount of IBNR's claim reserves is uncertain so it is necessary to estimate as accurately as possible. The estimation results of IBNR's claim reserves will affect the solvency and sustainability of the company. To calculate the estimated IBNR claim reserves, several approaches are used both deterministically and stochastically. This study uses a stochastic model with the GLM approach for data that is assumed to have an ODP distribution. Besides, this study also uses 2 different methods to calculate parameter estimates in the model, namely by performing parameter transformations and using the Verbeek algorithm. This study will compare the results of the IBNR claim reserve estimation obtained using these two methods in estimating the parameters in the model. The estimation results obtained indicate that the value of the IBNR claim reserves is the same. The advantage of the Verbeek algorithm is that the resulting parameter values ​​have interpretations.

Abstract

Masalah kontroversial adalah masalah yang memunculkan perbedaan pendapat dan dapat memunculkan argument dan persepsi yang beragam. Fakta menunjukkan bahwa sebagian besar calon guru masih belum terbiasa menyelesaikan masalah kontroversial. Tujuan penelitian ini adalah mengeksplorasi persepsi calon guru dalam menyelesaikan masalah kontroversial. Metode penelitian yang digunakan yaitu kualitatif deskriptif dengan pendekatan studi kasus. Instrumen tes dan wawancara digunakan untuk menggali informasi. Hasil dianalisis secara kualitatif dengan mengacu pada aspek persepsi yakni penyerapan, pemahaman, dan penilaian. Hasilnya adalah pada aspek penyerapan, calon guru menyampaikan respon yang beragam, baik yang salah maupun benar. Aspek pemahaman terjadi pada saat mengkaitkan pengetahuan yang sudah dimiliki dengan konsep pada permasalahan kontroversial. Aspek penilaian muncul pada saat calon guru memberikan sudut pandang yang berbeda dari masalah yang diberikan. Calon guru diharapkan sering menyelesaikan masalah yang bervariasi sehingga terbiasa menyelesaikan masalah kontroversial. Controversial issues are issues that give rise to differences of opinion and can lead to various arguments and perceptions. The facts show that most prospective teachers are still not used to solving controversial issues. The purpose of this research is to explore the perceptions of prospective teachers in solving controversial issues. The research method used is descriptive qualitative with a case study approach.. The results were analyzed qualitatively with reference to the aspects of perception, namely absorption, understanding, and assessment. The result is that in the absorption aspect, prospective teachers convey a variety of responses, both wrong and right. The understanding aspect occurs when relating existing knowledge to concepts on controversial issues. The assessment aspect appears when the prospective teacher gives a different perspective on the problem given. Prospective teachers are expected to often solve various problems so that they are used to solving controversial problems.

Abstract

Literasi Statistis adalah salah satu kecakapan yang diperlukan di era globalisasi. Perkembangan teknologi yang begitu cepat, berakibat pada ketersediaan data dalam skala besar. Untuk merespon fenomena ini, siswa perlu dibekali dengan literasi statistis sejak dini. Selain literasi bagi siswa, guru juga perlu memilikinya agar kualitas pembelajaran matematika di sekolah meningkat. Oleh karena itu, Departemen Matematika FMIPA Universitas Negeri Malang melaksanakan pengabdian kepada masyarakat terkait peningkatan literasi statistika bagi para guru Matematika di MGMP matematika SMA Kota Kediri. Kegiatan dilaksanakan dalam bentuk ceramah dan workshop. Berdasarkan kegiatan yang telah dilaksanakan, kegiatan ini memberikan pemahaman lebih bagi para guru tentang literasi statistis yang merupakan materi ajar baru dari contoh-contoh soal yang mungkin diberikan untuk meningkatkan nilai AKM siswa. Selain itu guru-guru juga memperoleh informasi terkait metode ajar yang sesuai untuk diterapkan ke siswa terutama untuk literasi numerasi ini.  Kata kunci— Literasi Statistika, Matematika, Pelatihan, Pengabdian Kepada Masyarakat Abstract Statistical Literacy is one of the skills needed in the era of globalization. The rapid development of technology has resulted in the availability of data on a large scale. To respond to this phenomenon, students need to be equipped with statistical literacy from an early age. In addition to literacy for students, teachers also need to have it so that the quality of learning mathematics in schools increases. Therefore, Mathematics Department, Faculty of Mathematics and Natural Sciences, State University of Malang carried out community service related to increasing statistical literacy for Mathematics high school teachers at Kediri City. Activities are carried out in the form of lectures and workshops. Based on the activities that have been carried out, this activity provides more understanding for teachers about statistical literacy which is a new teaching material from examples of questions that may be given to increase the value of students' AKM. In addition, teachers also obtain information related to appropriate teaching methods to apply to students, especially for numeracy literacy. Keywords— Statistics Literacy, Mathematics, Workshop, Community Service
