In the March 1994 issue of The Computing Teacher (Barrett, 1994), I discussed an emerging commercial technologythe assessment portfolioand practical strategies for its use. I suggested questions that readers should keep in mind as they consider using such technology to support alternative assessment. In this article, I expand on the questions that should be addressed before electronic portfolios are undertaken or technology is used to support observation and assessment. Thus far, observational assessment software is limited to two commercial packagesSunbursts Learner Profile and Auerbachs Grady Profileso this article will focus on electronic portfolios, which seem to have wider appeal and more flexibility. I will also ask a series of questions about their use, assuming that a commonly understood collaborative model will lead to more useful, productive, and successful assessment. According to Baker (as cited in Fenton, 1996), Assessment systems must be judged based on the value of the information they provide for students, teachers, curriculum specialists, principals, school board members, parents, and community members. All these stakeholders make choices about students, programs, curriculum and instruction. They must be considered within the context of intended use (p. 14). Five Questions for Context Five general questions will establish context that will help us make decisions about assessment in general. According to Fenton (1996), Assessment is the collection of relevant information that may be relied on for making decisions. Evaluation is the application of a standard and a decision-making system to assessment data to produce judgments about the amount and adequacy of the learning that has taken place (p. 13). What Is a Portfolio? Rick Stiggins (1994) defines a portfolio as a collection of student work that demonstrates achievement or improvement. The material to be collected and the story to be told can vary greatly as a function of the assessment context. The Northwest Regional Educational Laboratory offers a similar definition: A purposeful collection of student work that illustrates efforts, progress, and achievement. Stiggins (1994) also adds that a portfolio is a means of communicating about student growth and development and not a form of assessment (p. 87). How Are Portfolios Usually Stored Without a Computer? To store their materials, teachers and students have devised many strategies, whether notebooks and folders in file drawers or pizza boxes and other large containers. Some teachers also have used photographs, audiotape, and videotape to store samples of student work. What Should a Traditional or Electronic Portfolio Include? A portfolio should include the following elements:
Why Use Technology to Store Portfolios in Multimedia Format? Using a Decision Matrix: Asking and Answering Questions Before Using an Electronic Portfolio School teachers and administrators may find a decision matrix or template helpful in showing which programs or strategies to use based on available human and financial resources. I am often asked, What is the best portfolio program? and I always answer, It depends!on the assessment context and a variety of other human and technological factors in a classroom, school, or district. Resource Questions shows a few issues that must be addressed before this larger question can be definitively answered. And collaborative decision making means getting major stakeholders to answer questions that directly affect them. Questions About Assessment, Portfolios, and Context
Other Assessment Context Factors A few other important questions also need to be answered.
Multimedia Which of the following sorts of multimedia elements can be included in an electronic portfolio? Images Most people may know how to use a copy machine but not necessarily how to scan and display images on a computer. Such images are important for electronic portfolios because many learners most powerful sensory learning mode is visual. Images can instantly convey a message; consider, for example, the expression A picture is worth a thousand words. Students often produce documents that can be scanned or three-dimensional products that need to be photographed to be included in their portfolios. Sounds Video Text Student portfolios often include text, and it is text that most accurately demonstrates student thinking throughout their education. Portfolios have traditionally been folders that illustrate various stages of the writing process; electronic portfolios are no different and should allow students to collect and organize their written work and show their critical-thinking skills. Mixed Media Which Supporting Technologies Will Manage the Digitizing Process? Three specific types of technologies must be used to make sure the electronic portfolio process works as intended: authoring software, hardware add-ons, and platforms. Authoring Software Hardware Add-Ons Many people are learning how to use desktop computers for both professional and personal productivity. They may not know, however, the types of additional equipment that will enable multimedia production for presentations and portfolios. Fortunately, the addition of three inexpensive items to a desktop computer can produce a highly effective electronic-portfolio development station: a $99 eyeball video camera, a page scanner (less than $150), and a high-density floppy drive (such as a Zip drive; less than $150). Classroom Computers To use electronic portfolios effectively, you must make sure enough classroom computers are available so that students will have adequate development time. Also important are the operating systems used for specific computers. Such multimedia features as video and sound work best on more recent versions of the Macintosh and Windows 95 operating systems. Multimedia
Presentations and Electronic Portfolios: Multimedia Tools and Portfolio Development Choosing the right software tools is important. The key criterion in choosing software should be whether teachers and students can use it to create hypertext links to goals, outcomes, and various student artifacts (products and projects) that are displayed in multimedia format and that demonstrate student achievement. Again, Table 3 and Table 4 provide more information on multimedia products and electronic portfolio software. Conclusions Electronic portfolios can be used in many ways. The best use for a particular school or district depends on many factors but can be determined by considering not only the assessment process but also each possible stakeholder, whether teacher, student, parent, administrator, or community member. More research using these questions is now being done to determine the best technological strategy to use. Preliminary results can be found at http://transition.alaska.edu/www/portfolios.html.
