Portfolio Assessment in Mathematics Education. ERIC Digest.The ongoing reform of mathematics instruction creates a need to refine student assessment practices. Columba & Dolgos (1995) claim that evaluating student computational skills by traditional methods cannot provide enough information related to the component of the overall evaluative process needed in mathematics. Current standardized tests seem like to measure performance on rote mathematical tasks instead of creating environments for students to reason, communicate, and problem solve. In regard to measuring students' performance, NCTM (1989) states that "to demonstrate real growth in mathematical power, students need to demonstrate their ability to do major pieces of work that are more elaborate and time consuming than short exercises portfolios are some examples of more instructional and assessment activities" (p.36) in "Assessment Standards for School Mathematics." Like NCTM (1989), portfolio assessment is supported by many educators, because portfolio is considered as a collection of student work representing their mathematical power, a showcase for a student work or a place where many types of assignments, projects, reports, and writing can be collected (Columba & Dolgos, 1995). The idea of portfolio is close enough to satisfy educators' belief that assessment is most effective when it becomes an integral part of instruction. THE TYPES OF THE PORTFOLIO ASSESSMENTAccording to Columba & Dolgos (1995), there are basically three types of portfolios to consider
for classroom use.
* Showcase: This type of portfolio focuses on the student's best and most representative work. This type of portfolio is similar to an artist's portfolio where a variety of work is selected to reflect breadth of talent. Therefore, in this portfolio the student selects what he or she thinks is representative work. This folder is most often seen at open houses and parent visitations (Columba & Dolgos, 1995, p. 174175). * TeacherStudent Portfolio: This type of portfolio is often called the "working portfolio" or a "working folder". This is an interactive teacherstudent portfolio that aids in communication between teacher and student. The teacher and student conference to add or delete within the content of the portfolio (Columba & Dolgos, 1995, p. 175). *T eacher Alternative Assessment Portfolio: All the items in this type of portfolio are scored, rated, ranked, or evaluated. Teachers can keep individual student portfolios that are solely for the teacher's use as an assessment tool. This is a focused type of portfolio and is a model of the holistic approach to assessment (Columba & Dolgos, 1995, p. 175). FOCUS AND CONTENT OF MATHEMATICS PORTFOLIOSSome of the
main goals of portfolios are to see "student thinking, student's growth over
time, mathematical connections, student views of themselves as mathematicians,
and the problem solving process" (Stenmark, 1991, p.37). A variety of items can
be included in a mathematical portfolio in order to achieve these goals.
SUGGESTED ITEMS TO CONSIDER FOR MATHEMATICS PORTFOLIOS*Openended questions.
*A report of group project. *Work from another subject area. *Problems posed by student. *Art projects. *A book review. *Excerpts from a student's daily journal. *A table of contents. *Draft, revised, and final versions of student work on a complex mathematical problem. *A description by the teacher of a student activity that displayed understanding of a mathematical concept. *Newspaper and magazine articles. *A letter from the student to the reader of the portfolio, explaining each item. *Audio tapes of studentteacher interview. *A photo or sketch made by student of student's work with manipulatives. *Papers that show the student's correction of errors or misconceptions. *Notes from an interview by the teacher or another student. *Sample journal entries. *Work in the student's primary language. *Teachercomplicated checklists. *Videotapes of student's work. *A mathematical autobiography. *Mathematical research. THE ADVANTAGES OF PORTFOLIO ASSESSMENTBecause of the
limitation of traditional assessment tests, many educators have been
experimenting with alternative forms of assessment, and many have described the
advantages of portfolio assessments. According to Owings and Follo(1992), the
portfolio assessment can help students understand their strengths and
weaknesses. They also believe that students are more able to link successes and
failures to performance and may also facilitate goal setting through portfolio
assessment. Gilman, Andrew and Rafferty (1995, p.22) and Midkiff and Thomasson
(1993) have also identified several advantages of portfolios. According to them,
portfolios can be used to evaluate both products and process, and they allow the
integration of learning and assessment. Learning based on portfolio assessment
can be more studentdirected, and since evaluation is not based on single
scores, instruction based on learning styles is more easily evaluated. Moreover,
Gilman et al, (1995) claim that portfolios provide more information about
student progress and encourage students to be responsible of their own learning.
Therefore, students feel as they take bigger roles in the learning and the
assessment processes. Portfolios also help students develop skills necessary for
lifelong learning. On the other hand, portfolios reduce the teacher's daily
burden of grading papers. In sum, portfolios enable to assess global
understanding and thinking skills with a multidimensional form of evaluation.
THE DISADVANTAGES OF PORTFOLIO ASSESSMENTEven though
results in using portfolio assessments are positive, some educators found
disadvantages of using portfolios. In Koretz's (1994) study teachers indicated
some concerns about the use of portfolios. Mostly they mentioned that portfolio
assessment imposes substantial burdens on them such as time demands of planing
and administering problems. Moreover, it is harder to ensure that portfolios are
accurately recorded and scored students' performance; evaluation is more
subjective than traditional testing, and reliability and validity can be
questionable. Also, maintaining portfolios can be problematic and
timeconsuming. Finally, deciding the content of portfolios can be harder than
other assessment techniques.

(1996) show that "through the use of largescale portfolio assessment, students
can realize educational outcomes that are not afforded in an educational system
that focuses on traditional goals such as acquiring content knowledge and
performing well on standardized multiplechoice tests. Students were able to
reflect on and formulate statements about their personal beliefs and values,
their understandings of themselves as learners and writers, their abilities and
skills as writers, and their goals and aspirations" (p. 12). Moreover, the
conclusion drawn from the National Conference on Linking Liberal Arts and
Teacher Education (San Diego, California, October 67, 1994) was that portfolios
are a valuable tool for demonstrating through authentic evidence that the
professional skills necessary for teaching have been mastered, that many methods
of portfolio use are valuable, and that further research in this area is
necessary.
The portfolio assessment including openended questions can aid teachers in observing how students process mathematics information and also help differentiate the skill levels of individual students. However, the downside is that the use of portfolio assessment will require many teachers to face the difficult task of changing their teaching style. Great care must be used in proving the reliability, validity, and consistency of evaluating grades when using the portfolio assessment. RESOURCESAsturias, H. (1994). Implementing the assessment
