The reliability of The Spatial Memory subtest on the K-ABC

The Spatial Memory subtest appears on the Simultaneous Processing scale of the Kaufman Assessment Battery for Children, and is intended for children from 5-0 through 12-5 years of age. The purpose of this study was to evaluate the interscorer reliability of this subtest, due to reported scoring difficulties. Nineteen gifted children between the ages of 8-10 and 12-2 were administered the Spatial Memory subtest, and two independent examiners scored each subject's item responses. Results showed that the Spatial Memory subtest may be prone to scoring errors because there is no permanent record of responses. It is suggested that a permanent record of responses could improve interscorer reliability significantly and simplify the task of scoring this subtest for practcing psychologists.     

User assessment of media presentation rooms

Will student users prefer media presentation rooms specially designed, built, and equipped according to well-established and accepted environmental design and display system engineering principles to other, non-environmentally controlled media classrooms? The 503 university students questioned in this study did. The author concluded that given the proper instrument, students are capable of reliably evaluating factors in their learning environments — such things as acoustics, thermal conditions, visual display systems, and lighting — and that such factors are important to them.
