条目反应理论认为,每个测验条目有其自身固有的特征,比如难度、区分度等,这些特征与样本无关,也与其它条目无关。不同的潜在特质,适用于不同特性的条目来测量,这将提高测量精度和测验效率。条目的得分概率与潜在特质呈特定的回归关系,这些关系通常称为各种数学模型。本文还简要讨论了运用条目反应理论的注意事项。 According to the theory of item reaction, each test item has its own inherent characteristics, such as difficulty, degree of discrimination, etc. These features have nothing to do with the sample, nor with other items. Different potential traits apply to different characteristics of the entry to measure, which will improve the measurement accuracy and test efficiency. The item’s score probability has a specific regression relationship with potential traits, and these relationships are often referred to as various mathematical models. This article also briefly discusses the use of entry reaction theory considerations.
