With the advent of standards, which are statements constructed by authorities that outline the specific outcomes for a class, a new era of testing is emerging for teachers and learners. With standards, tests are based on acquisition of the essential content for each grade level. Standards based learning is different from traditional "norm referenced" learning. With norm referenced tests, the class average becomes the central system for rating the learner with others in the class but fails to compare the child on a state or national scale. Most states have some system of large scale testing that shows individual progress. Individual teacher made tests promote arguments and confusion.
We have already noted that some of the imprecision of the testing process may
be eliminated through the development of good objectives. A good rule of thumb
is to test for achievement of objectives. Poor teachers miss on this, causing
ill feelings on the part of students and poor course evaluations.
Before noting some approaches to assigning grades and assessment, it may be
useful to reflect on the grading, testing and assessment process. The following
questions are suggested for your consideration:

Comment: "The major
emphasis in American Universities is on knowing facts."
Many universities post the traditional percentage grading values in their public
documents. The general scheme often looks like this:
90% - 100% Excellent - A
80% - 89% Superior - B
70% - 79% Average - C
60% - 69% Poor - D
Below 60% Failure - F
For any type of assessment a percentage grade may be assigned, even when quantification can't be easily used as in the case of essay or performance based examinations.
A variation of the percentage scheme often found in university settings is the
normal curve grading system.
This is the system whereby the instructor determines the percentage of A's,
B's, etc., according to a pre-established distribution based on the Gausian
curve: A's = 7%; B's = 24%; C's = 38%; D's = 24% and F's = 7%.
Two approaches have emerged in recent yeas that are receiving attention through
practice and discussion. These are portfolio assessment and mastery or performance
assessment.
Mastery learning is based on a preset list of competencies that students should
know or be able to do. Various schemes may be used to establish a final grade;
usually the attainment of a particular number of competencies (I call this the
merit badge approach). Performance or mastery is the chief criterion for success.
Portfolio assessment represents a collection of evidence that convinces the
instructor that the objectives of the course have been met. The following notes
outline the main ideas of the portfolio approach:
1. Portfolios are well developed models of evaluation in other disciplines (art, photography, architecture) and programs (Scouts - done with a mentor; awarded with ceremony).
2. A portfolio is a collection of evidence that constitutes a compelling argument that you have achieved or made progress toward a goal. (Evidence tells anyone who may see your portfolio that you have learned something - always articulate the relationship between evidence and purpose).
3. Ask yourself "What evidence will show that the purpose of my portfolio has been met?" Types of evidence may include:
- Artifacts -- real things
- Reproductions -- photocopies
- Attestations -- statements from others
- Productions -- videotapes
- Reflections -- "As I was writing this I felt . . . "
- Captions -- each piece of evidence has a note (i.e.: "evidence that I talked with . . . ") and an explanation of why you think it is evidence.
4. The organization for the portfolio should include:
- Statement of your purpose (what you are striving to learn)
- Rationale (why you are doing the project)
- Evidence (caption each) - have a variety of compelling evidence (use only best)
- Reflection (how has this provoked thought)
- Theme (chronological, conceptual, factual, developmental)
- "Road Map" (how should I read or examine your portfolio).
5. With portfolios you know what is expected as you begin -- the system's fair, reasonable, dynamic, it displays strengths, multi purposes and is integrated.
6. I will provide you with additional information as needed particularly the team aspects of verifying evidence via the value added process. (What will the assessor know about me from this piece of evidence that would not be known if I hadn't included it?)
