Revision of an Evaluation Instrument: Will the Measuring Device Provide More Reliable or Valid Scores?
Witta, E. Lea; Witta, George T.
Factor analysis of the instrument used to evaluate student perceptions of an educational interactive video program has determined that seven constructs were being measured. All of these constructs, however, were not consistently measuring the same things. In fact, the variables on which the factors loaded changed for three of the factors from analysis of the 1995 data to analysis of the 1996 data. This instrument was revised to strengthen these constructs. Data collected in 1997 from 148 high school students indicate scores produced by the revised instrument are more reliable measures than those produced by the previous version. Logical assessment of the validity of the constructs provides some evidence of construct validity of the revised instrument. (Contains four tables and eight references.) (Author/SLD)
