Portfolio Assessment

• Portfolio

Portfolios are part . . .of the constructed
response assessment family

• For those training to be teachers, a portfolio
  means a collection of work in your teaching area
  (TaskStream) and has the following
  characteristics
• Multiple entries, many of which are self
  -selected.
• Assessments of your work conducted by others.
• Self-reflection (self-assessment) on the entries.
• On-going in nature with growth indicated.
• So would it make sense to have your students do
  portfolios?
• Caution What is the purpose for using the
  portfolio? Is it a working portfolio or a
  showcase portfolio? Who will see this work and
  why? Be sure students understand. Be sure you
  understand.
• Caution How will you evaluate the students
  portfolio? Overall, will you be using it for
  formative or summative assessment?
• Caution How much should go into a students
  portfolio? Key works only. Start slowly with key
  entries one at a time. Dont have students
  working on different entries of the portfolio all
  at once.

Portfolio Evaluation Guidelines. . . when
portfolios are used as summative assessment

• Because the portfolio is a collection rather than
  a single response, conducting quality assessment
  in this area requires one to make three somewhat
  unique decisions
• From the assortment of materials in the
  portfolio, what will be the focus of the
  evaluation? Three choices
• Students best work, most typical work, or his
  progress
• Who will select material for evaluation?
• Teacher, Student
• Who will evaluate?
• Teacher, Student
• From this point on, you can choose to evaluate
  using any scoring scheme discussed earlier with
  regard to essay and performance assessment (e.g.,
  holistic or analytic).

Thoughts to consider when you . . .Create Your
Scoring System

• Portfolio Scoring Systems Some Basic Choices
• Point method - Have a written outline for
  yourself which expresses your preconceived model
  of a high quality answer (i.e. key points to be
  included or skills to be demonstrated). Simply
  sum these points.
• Analytic method use a two-way scoring rubric
  (e.g., rate on subscales from 1 to 4) raters
  break the portfolio task into important
  predetermined sub-tasks associated with key
  points and skills.
• Holistic method use a one-way scoring rubric
  (e.g., rate on overall scale from 1 to 9) raters
  compare each portfolio taken as a whole to the
  model. There is a variation to this method in
  which the raters sort all the portfolios into
  three categories (for example below average,
  average, above average) then fine sort within
  categories. Some teachers use this method for A,
  B, C, D, F.
• Primary Trait method Used most often when the
  portfolio is a practical one (for example,
  Create a 10-page portfolio for a job
  interview.) The score is determined on whether
  it was complete or not sometimes we say met,
  or unmet. The students receive a predetermined
  score when the task is completed satisfactorily.
