Theory generalizability
WebbIn this study, the Classical test theory and generalizability theory were used for determination to reliability of scores obtained from measurement tool of mathematics success. 24 open-ended mathematics question of the TIMSS-1999 was applied to 203 students in 2007-spring semester. Internal consistency of scores was found as 0.92. Webb"'Reliability theory' is reinterpreted as a theory regarding the adequacy with which one can generalize from one observation to a universe of observations.
