IRT and Fisher information
TIMSS results are analyzed and TIMSS results are analyzed and calibrated using 3PL IRT modelcalibrated using 3PL IRT model
All parameters are determined All parameters are determined and published in Technical and published in Technical ReportReport
Therefore we can calculate Fisher Therefore we can calculate Fisher information function (information function (II) across ) across the scale (the scale (θθ))
Does it fit population profile in your country?
How much we get for what we pay
What we can do?
A quit the study quietlyB get mad and refuse to payC learn and take more active roleD ignore the problem and have fun
