Reading Comprehension and the Measure of Science Achievement Using the 1968-1969 ISCS Test and the Revised ISCS Test. Part III of An Analysis of Selected Aspects of the ISCS Model of Science Teaching.
Allen, David William
Reported is a study to investigate problems handicapped readers had with the Intermediate Science Curriculum Study (ISCS) test and of a method for adapting the test so that it might be more understandable. Seven questions related to the 1968-1969 ISCS test Probing the Natural World, Volume I were studied. The investigations of these questions was undertaken in two stages: (1) a pilot study using six classes in one junior high school, and (2) the major study which involved the testing of 28 seventh-grade ISCS classes at five junior high schools. The pilot study findings indicated the need for a revised test. In addition, achievement over the school year was examined using a repeated measure design. Item analysis data were used to see what changes in the psychometrics of the two instruments occurred as a result of revision. The Hotelling t-test was used to see if the revised ISCS test had a reduced correlation with reading as compared with the 1968-1969 ISCS test. Reading comprehension was found to be an important factor related to achievement on both the original and revised tests. The findings indicated that the oral-demonstration technique is a valid method to compensate for lack of reading ability. (Author/EB)
