Title: Formal Assessment


1
Formal Assessment
  • Week 6 7

2
Formal Assessment
  • Formal assessment is typical in the form of
    paper-pencil assessment or computer based. These
    tests are standardized because each student
    receives exactly the same assessment with the
    same instructions. The outcome is graded and the
    answers are standard based on information that
    the student is expected to possess.

3
Formal Assessment
  • Norm Referenced Tests
  • One form of formal assessment is a norm
    referenced test.
  • A norm referenced test or normative assessment is
    an evaluation where those being tested are
    compared to a sample group of his or her peers.
    This sample group is called the normative sample.
    Therefore each test taker is compared to the
    ability of his or her peers.

Formal Assessment
  • Norm Referenced Tests (NRTs) are typically
    multiple choice, but they can also be open-ended
    and short answer exams.
  • Norm referenced tests are the exams in which the
    students score is shown in as a percentile. Thus
    showing what percentile s/he scored according to
    the normative group. The design of NRTs is to
    rank test takers in comparison to other student
    who also took the test generally that year or at
    a given time.

5
Formal Assessment
  • Problems With Norm Referenced Tests
  • These types of tests can be biased against
    certain students depending on who the normative
    group was.
  • For example a normative group of suburban
    children might have the tendency to be biased
    against inner city students.
  • If the normative group were upper middle class
    Christian students, the test might be biased
    against all other possibilities and specifically
    lower socio-economical status, non- Christian
    students.

6
Formal Assessment
  • Problems with NRTs
  • Many mistakes can be made by using this type of
    test to make ultimate decisions on a students
    placement, graduation or retention because they
    only assess a small portion of a students
    educational ability. These assessments focus so
    much of their attention on information that is
    learned through memorization, rote, and routine
    learning.
  • NRTs often encourage teachers focusing on facts
    and not higher order thinking skills. It also can
    diminish educational land academic expectations.

7
Formal Assessment
  • Restraints
  • Norm referenced tests are usually given within
    certain time limits.
  • This can be a problem for some students because
    the concept of having 30 minutes for 20 questions
    can cause some anxiety.
  • NRTs also typically do not allow student to go
    back over a section once that section has been
    passed. This can be problematic for slower test
    takers who may not have finished one section, but
    finished another section early.

8
Formal Assessment
  • Accuracy
  • These assessments give a few questions of the
    many possibilities, thus the score is
    representative of how any given student might
    have done given all the questions.
  • However, when discussing scores and the accuracy
    of scores we must discuss validity and
    reliability.

9
Formal Assessment
  • Validity and reliability are extremely important
    in assessment.
  • In assessing the bias of an assessment requires
    looking at the validity and reliability.

10
Formal Assessment
  • Reliability
  • Reliability tests the consistency of the
    assessment. The question is each time this
    assessment is given does it assess the same thing
    each time. If you are at the market and you weigh
    your tomatoes and they weigh 2.2 lbs. You would
    expect that when the cashier weighs them they
    will weigh 2.2 lbs. Why? It is assume that the
    scale is reliable and will always weigh the
    tomatoes accurately.

11
Formal Assessment
  • Types of Reliability
  • One type of reliability of an assessment is
    internal consistency. It is measured by comparing
    one part (or half) of the assessment to another
    part (or half).
  • Another type of reliability of an assessment is
    alternate form. It is measured by creating two
    forms of the same test. The correlation between
    the two tests scores states the reliability.
  • Another type of reliability of an assessment is
    stability. This is measured by giving the
    assessment twice. The correlation of the scores
    from each time that the assessment was taken
    determines the reliability.

12
Formal Assessment
  • Validity
  • Validity refers to the accuracy of an assessment.
    In other words, does the assessment measure what
    it is supposed to measure. Validity is more
    important than reliability.

13
Formal Assessment
  • Types of Validity
  • If you are assessing the validity of the content,
    whether instructional objectives and content of
    the test match. A cumulative exam of a class
    would measure the validity of the overall course
    objectives. An assessment of two or three weeks
    would not measure the validity of the overall
    course objectives.

14
Formal Assessment
  • Types of Validity
  • If you are assessing the validity of the
    criterion of an assessment. This means when the
    validity is concurrent or predictive of external
    criterion. For example, if a 10th grade English
    final correlate highly with a statewide 10th
    grade English assessment, this would show a high
    concurrent validity.

15
Formal Assessment
  • Types of Validity
  • This type of validity shows the extent to which
    assessment corresponds, as predicted by a
    rationale or theory, with other variables.

16
Quick Quiz
  1. What is reliability?
  2. What is validity?
  3. What is the difference between reliability and
    validity?
  4. Why would validity be more important than
    reliability?
  • 5. In your own words tell how reliability and
    validity would be used in norm referenced
    testing.
  • 6.Would you use norm referenced tests? Why or why
    not?

17
Assignment for Week 6 7
  1. Read PowerPoint notes
  2. Read Ch. 4 and 5.
  3. Masters students read 30-40 additional pages
    and use Reading Report Form.
  4. Take Week 6 Quiz.
  5. Write up Do you think that norm referenced
    testing should be used in Christian education?
    Explain. How would this assessment help in your
    ministry? (This is Journal 6 7 for online
    students.)
  6. Begin working on writing assignment (see Week 9).
