Abstract

The invention discloses a self-adaptive online assessment system based on the IRT. The online assessment system comprises an assessment question bank building module, an online test module and a statistic analysis module. The assessment question bank building module is used for collecting test questions to build an assessment question bank and outputting test papers from the test question bank according to different screening rules; the online test module is used for performing multiple tests including the self-adaptive online test based on the IRT according to the test papers and automatically generating test data, and the self-adaptive online test based on the IRT is a dynamic self-adaptive online test based on a two-level score keeping module; the statistic analysis module is used for obtaining a statistic result automatically according to the test data and preset scoring standards and generating an evaluation report. The invention further discloses a self-adaptive online assessment system based on the IRT.

Description

technical field [0001] The invention relates to online evaluation technology, in particular to an IRT-based self-adaptive online evaluation system and its method. Background technique [0002] The traditional paper-and-pencil assessment can no longer meet the needs of teaching assessment, and cannot correctly reflect the knowledge mastery and cognition of students. With the development of Item Response Theory (IRT), IRT-based computer adaptive evaluation technology has attracted more and more attention and praise, especially the mature development of computer and network technology, which provides the development basis for IRT-based computer adaptive evaluation Conditions further promote the development of IRT-based computer adaptive assessment in the field of education. [0003] The traditional evaluation technology is that experts estimate the difficulty level of standard test questions according to the measurement group object, combine the test questions into an estimate...
