Loricifera Discussion

1. C. Longest option is the correct answer. Many students will choose the longest or most complex “scientific” sounding answer.

2. 
   B. Since A and B are opposites the answer is most likely A or B. A student might reason that since C is correct in the 1^st question, “single celled” cannot be correct in this item because it is an option in question #1. Therefore B must be correct. The question also lacks focus.
   

2. 
   B. The first question gives the answer to question #3. Small type is a problem for far sighted students.
   

2. 
   D. The first answer subsumes the next two, leaving only two viable answers, the odd answer or the one that subsumes the other two. Since only one answer can be correct D is the most likely choice. D is also grammatically complex making it appealing..
   

2. 
   D or A. Since option D subsumes the others it must be a correct answer even if answer A is intended. This type of error leaves the test maker in the awkward position of having to justify one answer as “better” than another, when two answers are clearly possible. Also this is tricky since no one invented loriciferans. They were discovered or the phylum was named. The use of “you” allows a student to argue.
   

2. 
   C is the only option that fits grammatically. Question 4 also clues the answer. There is also a change in the format that may confuse some students. D, while incorrect, is clued by capping of D. Students may miss the item for the wrong reason.
   

2. 
   B. Distracters are not plausible. The correct answer sounds more “scientific” than the others. These options are not parallel. Stacking is different than in previous items. Item stem should be in same column as the options.
   

2. 
   C. The answer depends on what is meant by “most important” and to whom. Any answer can be justified for this item. Option D sticks out as being longer, and not ending in “a.”
   

2. 
   B. The grain of sand is a clue to the answer for question 4. C is not plausible or you would not have asked the question. Option D is the same thing as A so D and A are eliminated. A linear scale should be included in the art to eliminate the depth perception problem or any answer could be correct. The slightly offset B clues the intended answer.
   

2. 
   B. The use of negatives in stem and options make this item difficult to understand even though the question is simple. Double negatives make this more difficult than it needs to be.
   

10. 
    B. Misnumbering throws students off if an answer sheet is used. Fauna in stem clues answer. Testing the same thing as item 7. “Appealing” is anthropomorphic term. Change in format of options confusing.
    

10. 
    B or D. No introduction to art, it just suddenly appears. Art is way to complex for partially sighted (enlargement would not help) or blind (too difficult to Braille). Distractors A and C not plausible because they are not easily arrived at with the numbers given in the problem. All options should be reasonable. All should have a rationale. Item stem not clear, should the animals be place along their long or short axis. Answer could be B or D depending on how the animals are arranged. Art not useful if the answer is B. Options not in logical order. Under what circumstances would anyone line up these animals?
    

10. 
    A or D Only the balance and graduated cylinder are in more than one option, cluing balance and graduated cylinder as very likely the correct answer. More than two piece of equipment can be used change “required” to “could be used.” “D.” is out of alignment. The use of you encourages arguments from students. “I can choose anything I want to, it may not be correct but it is my choice.”
    

10. 
    B Options do not grammatically answer the question. Probably way below intended grade level for this test.
    

10. 
    B Went from ridiculously simple to very specific trivial question. Options A and D do not parallel to others and do not grammatically answer the question. Sloppy editing. The “to” is supposed to be understood, but is not understood by all students.
    

10. 
    B Sloppy science. Question asks for a compound type only one compound given. Stem very long. Could have used a table. Example:
