The Development and Construct Validation of a Group Administered Test of Piaget's Formal Thought.
Staver, John R.; Gabel, Dorothy L.
This study investigates the reliability and construct validity of a group administered test of Piaget's formal operations stage. A related problem involving a learning effect associated with Piaget's clinical methods is also investigated. The Piagetian Logical Operations Test (PLOT), a group-administered instrument, was developed and field-tested. Eighty-four students in grades 10-12 participated in the field test. Subjects were randomly selected and assigned membership in one of two equal size groups having the same number of males and females from each grade. Data were obtained by clinical interview, PLOT, and intelligence test records. Subjects in group one received five clinical interviews followed by PLOT, while subjects in group two were administered the instruments in reverse order. Examination of the findings led to two conclusions: (1) the construct validity of the group test was partially established; (2) a learning effect was present in the PLOT total scores which was attributable to the previously administered clinical interviews, but no such effect was present, in general, in the clinical interview scores that were attributable to the administration of PLOT.
