Binary Choice Item # 1 - flaw(s)? The flaw is that the statement is unclear with the use of the pronoun 'they'.

__Evidence:__Commandment # 2 states, "thou shall not employ ambiguous statements in your assessment items...sentences in which pronouns are used can be unclear as to whom the pronoun refers."

__Binary Choice Item # 2 - flaw(s)?__ There are two flaws used in this item which are the use of difficult vocabulary and the use of a confusing and complicated sentence. Evidence: Commandment #4 states, "Thou shall not employ complex syntax in assessment items...avoid complicated sentence construction-use very simple sentences." Commandment #5 states, "Thou shall not use vocabulary that is more advanced than your audience...use vocabulary that is sutable for the students who will be taking your test."

Binary Choice Item # 3 - flaw(s)? There are two flaws in this item which are the use of two seperate ideas being asked and is stated in a very complicated and complex manner.

__Evidence:__ Commandment #4 states that "Thou should not employ complex syntax in assessment items and this statement breaks the commandment.

"The item writing guidlines state, "avoid items that include more than one concept...focus on a single concept in each test item."

Evidence: The item writing guidelines state, "minimize the use of negatives."

__Multiple-Choice Item # 1 - flaw(s)?__ This item has difficult vocabulary and it has a short stem and longer alternatives.

__Evidence:__ Commandment 5: "Thou shall not use vocabulary that is more advanced than your audience." "Lengthy stems and terse alternatives are preferred over skimpy stems and long alternatives."

__Multiple-Choice Item # 2 - flaw(s)?__ It uses the word "an" as the last word in the question.

__Evidence:__ Commandment 3: "Thou shall not provide students with unintended clues regarding appropriate responses."

__Multiple-Choice Item # 3 - flaw(s)?__ The use of option D- "all of the above."

__Evidence:__ According to the slides, a student that only knows two of the answers are correct and can guess that the other two answers are correct as well when the option of choosing "all of the above" is included.

__Multiple-Choice Item # 4 - flaw(s)?__ Item D is noticibly longer than all of the other choices.

__Evidence:__ "You don't want to give away clues with the item length." "Item writers frequently fail to realize that the length of a multiple-choice item can give an unintended clue to the correct answer." Commandment 4 states, "Thou shall not provide students with unintended clues regarding appropriate responses."

Matching Item # 1 - flaw(s)? There are a few flaws we found. The first is that there are the same number of responses in both columns. Also, the list in column A was alphabetical and column B was not. Evidence: "The total number of responses be a few more greater than the premises." Using more in column B would help the students.
