摘要
PURPOSE: A ubiquitous-based test (UBT) system using Rasch model and sequential probability ratio testing (SPRT) is provided to use Korean Rasch model and SPRT algorithm which have a simplest mathematical model and highest field-applicability, thereby providing intelligent educational content customized for the level of each learner. CONSTITUTION: An SPRT-based content extraction module is composed of an SPRT-based content part (102-1), which receives content information from a content providing device, and an SPRT-based content transmission part (102-2) which transmits content corresponding to the content information to a portable terminal. A source-based content extraction module is composed of a source-based content part, which receives source information of the content from the content providing device, and a source-based content transmission part which transmits content corresponding to the content source information to the portable terminal. The content part of a content-coupling module (106) receiving content-coupling information accesses the content of each electronic-learning server and ubiquitous-learning server containing the content.
