You have anticipated my response. The principle is that Web-based tests and instruction are not necessarily considered "general-purpose content." Rather, they may, at least in some circumstances, be considered "special-purpose content." In order to align the remainder of the document with this approach, I think that this approach may also necessitate a change to the definition of "Text content...", which, of course is under revision anyway. Essentially, I would suggest that, pending further revision, the following phrase be deleted: "that content represents a general mix of purposes (information, education, entertainment, commerce)". > -----Original Message----- > From: Ian Jacobs [mailto:ij@w3.org] > Sent: Thursday, January 25, 2001 6:54 PM > To: Hansen, Eric > Cc: UA List (E-mail); Ian Jacobs (E-mail) > Subject: Re: Instruction and Assessment > > > "Hansen, Eric" wrote: > > > > Known Limitation of the UA Guidelines regarding Instruction > and Assessment > > > > In section 1.3, I suggest adding a known limitation > regarding effectiveness > > of instruction or assessments. > > Hi Eric, > > Here's an argument against adding this: Section 1.2 of the 16 Jan > draft [1] includes this statement: > > This document was designed specifically to improve > the accessibility of mainstream user agents with multimedia > capabilities for users with one or more disabilities > (including visual, hearing, physical, and cognitive). > In this context, a mainstream user agent is one designed > for the general public to handle general-purpose content > in ordinary operating conditions. > > Instructions and assessments would not be > general-purpose content; this is a particular environment > with particular restrictions. > > So is your concern adequately addressed by the existing statement? > > - Ian > > [1] http://www.w3.org/WAI/UA/WD-UAAG10-20010116/#target > > > > This is important because provision of > > alternative representations is central to our accessibility > strategy, yet > > depending on what is being taught or assessed, provision of such > > alternatives may 'short circuit' or damage the validity of > an assessment or > > the teaching effectiveness of an instructional module.
