Abstract

The purpose of the present study is to validate an Arabic version of STEBI-B using Rasch model techniques. The validated Arabic version of the instrument (A-STEBI-B) was administered to a sample of (168) Jordanian prospective elementary school science teachers enrolled in the Hashemite University classroom teacher preparation program. Rasch analysis program, WINSTEPS 3.69 was used to calculate the infit and outfit MNSQ and ZSTD statistics. The values of infit and outfit MNSQ and ZSTD of the 23 items in both scales ( 10 items of OE and 13 items of PE) fits the model well. This means that each item contributes to mesurement of only one construct in both scales, (i.e. outcome expectancy and personal teaching efficacy). In conclusion, the arabic version of STEBI-B is valid and reliable measure for use in jordan.
