Abstract

Statistics is a part of mathematics lessons in senior high school XII classes as well as mathematics specialization class XII. A comprehensive understanding of the basic concepts of statistics is needed to convey the material in class. The results of the discussion with the Mathematics MGMP of Kediri City, a workshop is needed to deepen the understanding of mathematics teachers, especially in the material of normal distribution and binomial distribution. In addition, Material about item analysis and standard setting is need to be introduced. Both materials can be used in evaluating learning. The workshop was held in two days. The first workshop held on 4 November 2020.  Material for this day was normal distribution. At the end of the activity on this date, participants were given practice questions that should to be uploaded on google classroom. Second workshop held on 17 November 2020. Participatn are given material about binomial distribution, item analysis, and standard setting. This workshop has increased the level of understanding of participants on the material of binomial distribution and normal distribution. The increase in understanding is measured by the evaluation of the answers to the practice questions collected by the participants and the evaluation of the resource persons during the workshop activity. The next workshop can be conducted with the theme of statistical inferential analysis in educational research. The statistical analysis is very helpful for educators to analyze research data in education.

Abstract

Penilaian merupakan akhir dari proses pembelajaran yang dapat dilakukan melalui ujian. Soal yang digunakan harus mampu mengukur kemampuan peserta didik. Classical Test Theory (CTT) dan Rasch model merupakan analisis statistika untuk menganalis butir soal. Desain dalam penelitian ini adalah penelitian deskriptif. Hasil analisis terhadap 50 soal menggunakan metode CTT, didapatkan hasil bahwa hanya 21 soal yang memenuhi kriteria item difficulty dan item discriminant. Analisis Rasch model, memberikan informasi bahwa secara keseluruhan kualitas soal dikatakan baik berdasarkan pola kurva item information function. Analisis ini juga memberikan informasi terdapat 42 soal yang layak karena memenuhi kriteria item fit, dan 8 soal yang harus dievaluasi lagi. Analisis menggunakan Rasch model lebih baik dibandingan dengan CTT, sehingga 8 soal yang tidak layak berdasarkan analisis tersebut harus dievaluasi dengan mengubah bentuk studi kasus pada soal tersebut dan membuat inovasi metode pembelajaran terkait materi pada 8 soal tersebut.Kata kunci: analisis soal, Classical Test Theory, Rasch model.
