In this study 6,942 items from two standardized achievement test batteries--the Stanford (Early School Achievement Battery, Achievement Battery, and Test of Academic Skills) and the Comprehensive Test of Basic Skills--were analyzed. Focus was on determining: (1) the extent to which these test batteries included general cognitive operations (GCOs)…

This study added extraneous information and increased syntactical complexity to determine the relative importance of computational and reading abilities in solving arithmetic word problems. Analyzing tests of 200 sixth graders indicated the combined abilities accounted for 54 percent of the variance in solution accuracy. (BS)

In most reliability studies, the precision of a reliability estimate varies inversely with the number of examinees (sample size). Thus, to achieve a given level of accuracy, some minimum sample size is required. An approximation for this minimum size may be made if some reasonable assumptions regarding the mean and standard deviation of the test…

The ability to correctly answer reading comprehension test items, without having read the accompanying reading passage, was compared for third grade learning disabled students and their peers from a regular classroom. In the first experiment, fourteen multiple choice items were selected from the Stanford Achievement Test. No reading passages were…

The reading portion of the Michigan Educational Assessment Program (MEAP) was equated to the reading comprehension subtest of the Comprehensive Tests of Basic Skills (CTBS) using the Rasch Model. Both tests were administered to 366 low achieving fourth grade students. MEAP was treated as both a 95-item test and a 19-item (number of objectives…
