<strong>to</strong> the answer sequence (e.g., ABBABBABB). Try <strong>to</strong> have a<br />
nearly equal proportion of As, Bs, Cs, etc., as the correct<br />
answers.<br />
Concerns about the construction of the stem portion of the<br />
question<br />
• Use the stem <strong>to</strong> present the problem or question as clearly<br />
as possible.<br />
• Use direct questions rather than incomplete statements for<br />
the stem.<br />
• Include as much of the item as possible in the stem so that<br />
alternatives can be kept brief. However, when applying<br />
definitions, it is recommended you place the terms in the<br />
stem and use the definitions as options, although this makes<br />
the questions rather long.<br />
Concerns about the construction of the responses or<br />
options of the question<br />
• List options on separate lines rather than including them as<br />
part of the stem, so that all options can be clearly<br />
distinguished.<br />
• Keep all alternatives in a similar format (i.e., all phrases, all<br />
sentences, etc.).<br />
• Be certain that all options are plausible responses <strong>to</strong> the<br />
stem. Poor alternatives should not be included just for the<br />
sake of having more options.<br />
• Check all choices for grammatical consistency with the<br />
stem.<br />
• Try <strong>to</strong> make alternatives for an item approximately the same<br />
length. Making the correct response consistently longer is a<br />
common error.<br />
• Use misconceptions students have displayed in class, or<br />
errors commonly made by students in the class, as the<br />
basis for incorrect alternatives.<br />
• Use “all of the above” and “none of the above” sparingly<br />
since students, on the basis of incomplete knowledge,<br />
choose these alternatives often.<br />
• Use capital letters (A, B, C, D, E) as response signs rather<br />
than lower-case letters (“a” gets confused with “d” and “c”<br />
with “e” if the quality of the typeface or duplication is poor).<br />
True/False Items<br />
Advantages -- True/false items are relatively easy <strong>to</strong> prepare<br />
since each item comes rather directly from the content. They offer<br />
the instruc<strong>to</strong>r the opportunity <strong>to</strong> write questions that cover more<br />
