OK, I tried to sty out of this, but...
My field is education and educational theory. As a member of the Colorado Goals 2000 task force, part of my job was to oversee the implementation of the state standards and of standards-based education goals in general. When I was a member of North Central Accreditation visiting teams, my specific specialty was analyzing program standards. In my most recent consulting work, one of my primary goals was adjusting curriculum design to the world of standards.
I understand the term
standards, and I know how PADI is using the term.
The phrase "minimum standards" has absolutely, positively no meaning in that context. There is only one defined level of performance in a standard, and in this case, PADI calls it
mastery.
Those of you who are repeatedly talking about a system where you have different levels of standards are not talking about standards based eduction; you are referring to something altogether different and misusing the term.
What bothers me is that I have had to say this many times in the past, with many of the same people involved. That they are still repeating the same mistaken phrases even when they have had the error explained is a mystery to me. It must be either lack of attention, lack of understanding, or intentional misrepresentation.
In some skills, the standard of performance appears to change, but people who think so are not understanding the system. Let's take the previously mentioned mask skills, for example. The first time a student does it, it is a simple partial mask flood. There is a standard for a partial mask flood. That standard is different from the standard for the final skill that will be performed in the sequence. It is because of the idea of a
progressive mastery of skills. You have the student master a skill at a small level and find success. Then you move to a more complicated skill (full mask clear) which the student is to master. Success breeds success. Then you get more and more complicated, with the student mastering each level of complication.
About half way through the entire sequence, the student must swim a specified distance in water too deep to stand in (3 1/2 feet of water would be a standards violation) with no mask and then put it on. (The standard says nothing about doing it on the knees, and my students do not so so.) Completing that standard does not mean that the student is done with mask skills--it means the student has mastered
that level of the learning sequence. The student still must do 4 mask skills in the open water.
This is contrasted with what I have seen in most technical programs I have witnessed, where students are given minimal instruction and practice and then thrust into the evaluation of a skill at the highest level. The instructors feel really proud of what good, tough instructor they are because students experience many failures before they finally succeed--unless they quit first . (Failure breed failure.)
Standards appear to be vaguely written because they must be so to be valid. A yearning for countable numbers is because of a psychological need some people have for the false sense of objectivity in numbers. They are so focused on
reliability that they are willing to sacrifice
validity. (I wrote a very long explanation of the difference between validity and reliability in assessment quite a bit back; let me just summarize by saying too much focus on reliability often results in assessments which are not valid measurements of what you are trying to assess.)
For a good explanation of a lot of this, please look at
