Hearing-Impaired Students' Performance on the Piagetian Liquid Horizontality Test: An Analysis and Synthesis.
Witters-Churchill, Laurie J.; Witters, Lee A.
The paper provides an analysis and synthesis of studies with hearing impaired and other populations concerning the cognitive development of the principle of liquid horizontality--the idea that still water remains invariantly level regardless of the angle of the container. Three major questions focused the investigation: (1) What are the effects of development on students' performance on the Piagetian liquid horizontality test? (2) Do special training and shape of bottle influence the students' performance on the test? (3) What effects of gender are found on the students' performance on the test? Results suggested that hearing impairment has little impact on the development of this cognitive concept; that training in scientific reasoning with hands-on experiments improved performance in hearing impaired as well as other groups; and that sex differences in development of the concept appear to exist in normal but not exceptional (including hearing impaired) groups. Implications for instruction include the value of multisensory experiential learning for all groups and the need to minimize sex stereotypes. Recommendations include: that researchers provide sufficient information to allow replication, that research journals publish nonsignificant findings, that a meta-analysis be conducted to determine the magnitude of reported sex differences, and that more studies with exceptional populations be conducted.
