Interactive methods and systems
The present application provides an interactive method and system relates to the field of information exchange. Said method comprising: contacting with an object in response to the user's body, receiving the object sent to the user's body comprises at least part of a wave signal transmission medium. Said system comprising: a receiving means, responsive to an object in contact with the user's body, receiving said emitted by the object at least a portion of the user's body comprises a wave signal to the transmission medium. The interaction method and system, to help users natural and efficient interaction process completion information, simplifying the interaction process, to improve the interaction efficiency.
This study was designed to provide an empirical comparison of three IRT calibration programs, IRTPRO, BILOG-MG, and IRTLRDIF, all of which can be used for detecting differential item functioning (DIF). The three programs were compared for each of three dichotomous IRT models, the one-parameter logistic, the two-parameter logistic, and the three-parameter logistic models. Results from each of these programs were examined using data from a test designed to predict high school graduation test results in a large Southeastern US state. Results suggested that all three programs detected DIF differently.
