The study investigated the effect of "item density" on item difficulty in passage-related language tests. Item density refers to the number and frequency of items in relation to clear text. The format used was a passage with underlinings to signal the language situations out of which the items were constructed. American College Testing…

This investigation of the effect of making a set of alternatives conform grammatically to a test item stem showed there is subject sensitivity to such cues. Content-free versions of American College Testing Assessment Experimental Social Science items representing singular-plural and vowel-consonant agreement without inappropriate grammatical…

Two studies examined the effect of making the correct answer of a multiple choice test item grammatically consistent with the item. American College Testing Assessment experimental items were constructed to investigate grammatical compliance to investigate grammatical compliance for plural-singular and vowel-consonant agreement. Results suggest…

Whether the shaping of test items can itself result in qualitative differences in examinees' comprehension of reading passages was studied using the Pearson-Johnson item classification system. The specific practice studied incorporated, within an item stem line, references that point the examinee to a specific location within a reading passage.…

This study investigated the effect of diagram formats on performance on geometry items in order to determine whether certain examinees are affected by different item formats and whether such differences arise from the different intellectual demands made by these formats. Thirty-two experimental, multiple-choice geometry items were administered in…

This study compared student performance on language-usage test items presented in two different formats: as discrete sentences and as items embedded in passages. American College Testing (ACT) Program's Assessment experimental units were constructed that presented 40 items in the two different formats. Results suggest item presentation may not…

A study compared student performance on language-usage test items embedded in a passage when the location of the answer was varied. American College Testing (ACT) Assessment experimental units were constructed that presented 35 items whose sequence of foils was varied so that each foil appeared once as the "no change" option embedded in…

The combinational-format item (CFI)--multiple-choice item with combinations of alternatives presented as response choices--was studied to determine whether CFIs were different from regular multiple-choice items in item characteristics or in cognitive processing demands. Three undergraduate Foundations of Education classes (consisting of a total of…

This study investigated the effects of verbal factors on item performance in mathematics tests. Experimental tryout units were constructed that varied the verbal load of each of 21 mathematics test items. Each tryout unit was randomly assembled to include A, B and C versions of items so that no examinee took a unit of only one item format. Each…

Writers of mathematics test items, especially those who write for standardized tests, are often advised to arrange the answer options in logical order, usually ascending or descending numerical order. In this study, 32 mathematics items were selected for inclusion in four experimental pretest units, each consisting of 16 items. Two versions…
