Implementing
Performance Assessment
Amy C. Brualdi
Introduction
If
you are like most teachers, it probably is a common practice for you
to devise some sort of test to determine whether a previously taught
concept has been learned before introducing something new to your
students. Probably, this will be either a completion or multiple-choice
test. However, it is difficult to write completion or multiple-choice
tests that go beyond the recall level. For example, the results of
an English test may indicate that a student knows each story has a
beginning, a middle, and an end. However, these results do not guarantee
that a student will write a story with a clear beginning, middle,
and end. Because of this, educators have advocated the use of performance-based
assessments.
Performance-based
assessments "represent a set of strategies for the...application
of knowledge, skills, and work habits through the performance of tasks
that are meaningful and engaging to students" (Hibbard and others,
1996, p. 5). This type of assessment provides teachers with information
about how a child understands and applies knowledge. Also, teachers
can integrate performance-based assessments into the instructional
process to provide additional learning experiences for students.
The
benefits of performance-based assessments are well documented. However,
some teachers are hesitant to implement them in their classrooms.
Commonly, this is because these teachers feel they don't know enough
about how to fairly assess a student's performance (Airasian, 1991).
Another reason for reluctance in using performance-based assessments
may be previous experiences with them when the execution was unsuccessful
or the results were inconclusive (Stiggins, 1994). The purpose of
this digest is to outline the basic steps that you can take to plan
and execute effective performance-based assessments.
Defining The
Purpose Of The Performance-Based Assessment
In
order to administer any good assessment, you must have a clearly defined
purpose. Thus, you must ask yourself several important questions:
- What
concept, skill, or knowledge am I trying to assess?
- What should
my students know?
- At what
level should my students be performing?
- What
type of knowledge is being assessed: reasoning, memory, or process
(Stiggins, 1994)?
By answering
these questions, you can decide what type of activity best suits your
assessment needs.
Choosing The
Activity
After
you define the purpose of the assessment, you can make decisions concerning
the activity. There are some things that you must take into account
before you choose the activity: time constraints, availability of
resources in the classroom, and how much data is necessary in order
to make an informed decision about the quality of a student's performance
(This consideration is frequently referred to as sampling.).
The
literature distinguishes between two types of performance-based assessment
activities that you can implement in your classroom: informal and
formal (Airasian, 1991; Popham, 1995; Stiggins, 1994). When a student
is being informally assessed, the student does not know that the assessment
is taking place. As a teacher, you probably use informal performance
assessments all the time. One example of something that you may assess
in this manner is how children interact with other children (Stiggins,
1994). You also may use informal assessment to assess a student's
typical behavior or work habits.
A
student who is being formally assessed knows that you are evaluating
him/her. When a student's performance is formally assessed, you may
either have the student perform a task or complete a project. You
can either observe the student as he/she performs specific tasks or
evaluate the quality of finished products.
You
must beware that not all hands-on activities can be used as performance-based
assessments (Wiggins, 1993). Performance-based assessments require
individuals to apply their knowledge and skills in context, not merely
completing a task on cue.
Defining The
Criteria
After
you have determined the activity as well as what tasks will be included
in the activity, you need to define which elements of the project/task
you shall use to determine the success of the student's performance.
Sometimes, you may be able to find these criteria in local and state
curriculums or other published documents (Airasian, 1991). Although
these resources may prove to be very useful to you, please note that
some lists of criteria may include too many skills or concepts or
may not fit your needs exactly. With this in mind, you must be certain
to review criteria lists before applying any of them to your performance-based
assessment.
You
must develop your own criteria most of the time. When you need to
do this, Airasian (1991, p. 244) suggests that you complete the following
steps:
- Identify
the overall performance or task to be assessed, and perform it yourself
or imagine yourself performing it.
- List
the important aspects of the performance or product.
- Try
to limit the number of performance criteria, so they can all be
observed during a pupil's performance.
- If
possible, have groups of teachers think through the important behaviors
included in a task.
- Express
the performance criteria in terms of observable pupil behaviors
or product characteristics.
- Don't
use ambiguous words that cloud the meaning of the performance criteria.
- Arrange
the performance criteria in the order in which they are likely to
be observed.
You
may even wish to allow your students to participate in this process.
You can do this by asking the students to name the elements of the
project/task that they would use to determine how successfully it
was completed (Stix, 1997).
Having
clearly defined criteria will make it easier for you to remain objective
during the assessment. The reason for this is the fact that you will
know exactly which skills and/or concepts that you are supposed to
be assessing. If your students were not already involved in the process
of determining the criteria, you will usually want to share them with
your students. This will help students know exactly what is expected
of them.
Creating Performance
Rubrics
As
opposed to most traditional forms of testing, performance-based assessments
don't have clear-cut right or wrong answers. Rather, there are degrees
to which a person is successful or unsuccessful. Thus, you need to
evaluate the performance in a way that will allow you to take those
varying degrees into consideration. This can be accomplished by creating
rubrics.
A
rubric is a rating system by which teachers can determine at what
level of proficiency a student is able to perform a task or display
knowledge of a concept. With rubrics, you can define the different
levels of proficiency for each criterion. Like the process of developing
criteria, you can either utilize previously developed rubrics or create
your own. When using any type of rubric, you need to be certain that
the rubrics are fair and simple. Also, the performance at each level
must be clearly defined and accurately reflect its corresponding criterion
(or subcategory) (Airasian, 1991; Popham, 1995; Stiggins, 1994).
When
deciding how to communicate the varying levels of proficiency, you
may wish to use impartial words instead of numerical or letter grades
(Stix, 1997). For instance, you may want to use the following scale:
word, sentence, page, chapter, book. However, words such as "novice,"
"apprentice," "proficient," and "excellent"
are frequently used.
As
with criteria development, allowing your students to assist in the
creation of rubrics may be a good learning experience for them. You
can engage students in this process by showing them examples of the
same task performed/project completed at different levels and discuss
to what degree the different elements of the criteria were displayed.
However, if your students do not help to create the different rubrics,
you will probably want to share those rubrics with your students before
they complete the task or project.
Assessing
The Performance
Using
this information, you can give feedback on a student's performance
either in the form of a narrative report or a grade. There are several
different ways to record the results of performance-based assessments
(Airasian, 1991; Stiggins, 1994):
