A Study on a Method of Estimating the Difficulty of Quizzes Focused on Quiz Types

Abstract

In general, Item Response Theory (IRT) is used to quantify the difficulty level of quizzes. In order to estimate the difficulty level of the quizzes, students need to answer the quizzes in advance. However, it is hard to make students answer all quizzes in the item bank. Therefore, a method of estimating the difficulty level of not answered quizzes is studied. This study estimates the difficulty level of not answered quizzes by focusing on quiz types. Firstly, the relationship between quiz types and the difficulty level are analyzed. Next, from the result of the analyses, a procedure for estimating the difficulty level of quizzes focused on quiz types is discussed. The experiment results of comparing the proposed method with an IRT method showed that the value of the difficulty level estimated using the proposed method is close to the value estimated using IRT.
