PHYSICS PROBLEM SOLVING

(^) From Table 4-14 it is clear that most requests (29%) lead to Clarification.
Somtimes (16%) a Modified Claim is the result of the Reqeust. Group 4A is an excellent
example of how requested clarification statements (Grounds, Warrants, and Backings)
and Modified Claims elaborate an idea. The members of this group often continue one
another’s thoughts with a clarifying phrase following a Request. In Table 4-17, line 50,
member MR clarifies the Warrant, although the Warrant was not requested. Compare
this to lines 55-59, which illustrate the clarification of a Ground in response to a Request.
When member MR says “The weight of the bar,” she clarifies MK’s “What?” in line 56.
She then elaborates the original Claim member RM made in line 49 by specifying the
location of the “weight right here.” What is equally interesting is the Request in line 56
leads not only to the Modified Claim in line 58, but supporting Backings and Grounds in
lines 58 and 59. This is a example of how a requested Modified Claim clarifies the
meaning of the initial Claim.
