I transmitted the substance of this post to Math-Teach on 01 Feb 2014 ~15:00-0800 but so far (02 Feb 09:40-0800) it had not shown up on the Math-Teach archives at <http://bit.ly/eOTrs1>. Here's a second try:

 In the abstract of my post "The Defiant Parents: Testing’s Discontents – Response to Hunt" [Hake (2014)] I wrote:

 "Modesty forbids mention of these examples. . . .[[of "formative evaluation" in the JCSEE sense]]. . . . . .  7. 'SET's Are Not Valid Gauges of Students' Higher-Level Learning #2' [Hake (2011b)] at <http://bit.ly/jLZaz5>."

 In response, GS Chandy (2014) questioned the use of the apostrophe in the word "SET's" claiming that "SET's" means "SET IS".

 Not so!  According to Wikipedia's entry on "Apostrophe " at <http://bit.ly/LDZAwy>:

 "USE IN FORMING CERTAIN PLURALS: An apostrophe is used by some writers to form a plural for abbreviations, acronyms, and symbols where adding just "s" rather than " 's " may leave things ambiguous or inelegant."
