Test Taker Counseling Matrix - RMS & KJS

The right mark score (RMS) student test taker counseling matrix for biology is the same as for nursing in the prior post. Again there is another example of two items with the same difficulty (58) but classified differently: unfinished and discriminating. Question 50 was a tally item. 

The knowledge and judgment scoring (KJS) student test taker counseling matrix for biology presents a student view of the test not possible with just RMSing. 

  • (E)xpected             most marked & most right
  • (G)uessing             few marked & few right
  • (M)isconception      most marked & few right
  • (D)iscriminating      few marked & most right

As students select items for their individualized tests they are also voting for item performance. Item 50 is an example of a tally that is not scored for a grade.
Item 6 (58%) was labeled unfinished by the test maker view and here is labeled the only misconception by the test taker view.
Both sets of data  can be sorted (mined) for a variety of relationships. One is to look for copying.
