Rubric - Evaluation of a Web Site

Introduction

Among the ancients, according to Columella, Vitruvius, and Pliny, the word rubrica, or rubric, signified the red earth used by carpenters to mark on wood the line to follow in cutting it; according to Juvenal the same name was applied to the red titles under which the jurisconsults arranged the announcements of laws. Soon the red colours, at first used exclusively for writing the titles, passed to the indications or remarks made on a given text.

Today in academia we refer to a rubric as a scoring tool rather than as it was originally referenced: notes in red ink used in grading text. We maintain the spirit of the original meaning of rubric since the term still refers to a general rule or guide for judging something of importance. More specifically, a scoring rubric consists of a fixed scale and a list of the characteristics for describing performance for each of the score points on the scale. Since rubrics describe levels of performance, they provide important information to teachers, parents and others interested in what students know and are able to do. Perhaps most importantly, rubrics provide a clear statement to students, teachers and parents as to what is considered important and worth learning, even before the learning has occurred because "once educators incorporate multiple intelligent strategies into the teaching repertoire, it becomes important to rethink the approach to assessment."

"If you get something wrong, your teacher can prove you knew what you were supposed to do."

A Typical Rubric

A typical rubric is based upon what we have learned, rather than what we have been taught. As such it is an authentic assessment tool designed to simulate real life activities and experiences; more precisely, it is a scoring guide that differentiates between levels of development in a specific area of performance or behavior; they differ from traditional methods of assessment in that they examine activity in the actual process of learning, clearly showing us how our work is being evaluated.

Technical Requirements of Rubrics

All of the features below apply to what might be termed a valid rubric.

Features: All rubrics can be created in a variety of forms and levels of complexity, yet contain three common features: one, they focus on measuring a stated objective (performance, behavior or quality); two, they use a range to rate performance: three, they contain specific performance characteristics arranged in levels indicating the degree to which a standard has been met.

The descriptors (score, level and so forth) reflect a continuity in the degree of difference between say a 1 and a 2 and a 4 and a 5.

Each descriptor is constructed in terms of criteria language used parallel to all other sentences.

The rubric is coherent or focuses on the same criteria throughout. and hence refers to the variance of quality for the (fixed) criteria, and not in the language which shifts in importance or introduces a new criteria.

When multiple rubrics are uses there is an apt weighing, not arbitrary weighing of each criterion in reference to the others.

A valid rubric is one which should enable assessment of smoothness and formativeness of a presentation with valid inferences toward this presentation made to the degree that what is scored is what is central to the presentation. The proposed differences in quality should:

* reflect task analysis and be based upon work across the full range of presentation.

* describe qualitative, not quantitative, differences

* not confuse merely correlative behaviors with actual authentic criteria.

The rubric should be reliable in that a consistent scoring in terms of both judges and time using evaluative language (excellent, poor, or novice, expert) is translated into language which is highly descriptive (better than, worse than) which helps judges recognize the salient and distinctive features of each level of presentation.

Do You Need A Rubric?

Whether we are a student doing research, a shopper seeking a product customer satisfaction rating or a award program owner, all of us must realize that anyone can publish anything on the interest at anytime. Internet resources are not necessarily reviewed or "filtered" like books, magazines or videos which pass through an editor or editorial staff, or are selected by a librarian during collection development. Common sense says why not have an evaluation criteria rubric for internet resources review?

What would you include in the basic criteria for doing research?

Authority: Decide whether an individual, an organization or an agency who is recognized as an expert in a field who is knowledgeable, qualified and reliable.

* Authors qualifications and affiliation: Is the author or information provider clearly identified? Is the data included about the author?

* Is there a contact person or address available: Can the webmaster be contacted easily?

* Is there evidence of quality control? Is information presented on an official organizational web site; online journals that use peer review by editors or others; posting of information taken from books or journals that previously underwent a quality control process.

Accuracy: Cana it be verifiable, dependable and error-free?

Motivation: Is the author supplying real, reliable information or is he or she just trying to sell an idea or opinion?

Objectivity: Is the material presented selectively or in a unbalanced manner which is only one side of an issue or was some information left out? Is the information merely an opinion on an issue? To what extent is the creator trying to change our opinion?

Currency of Information: Relates to the date of information, publication date or date of last revision. As in printed sources, some work is timeless, like classic novels or much of history. Other work has limited life because of changes in the discipline like technology. Up to date links add to the validity of the entire site.

Designing a Rubric

Literally thousands of expertly designed rubrics are available on the internet. But to begin, rubrics can be either general or specific. General rubrics can be applied to various tasks or they can be specific like the one mentioned earlier for evaluating an individual web site. Both types of rubrics benefit the user and can also be analytical or holistic. If a rubric has two or more separate scales it is called an analytical rubric, as it takes apart or breaks up the rating system for each trait; a rubric that uses only a single scale is called a holistic rubric. A holistic rubric is more efficient when criteria cannot be separated, however an analytical rubric will yield more detailed information, and, therefore, more specific feed back.

But you can also adapt a rubric - modify or combine existing rubrics; re word parts of the rubric; drop or change one or more scales of an analytical rubric, omit criteria that are not relevant to the outcome you are measuring; mix and match scales from different rubrics; add a "no response: category at the bottom of the scale; divide a holistic rubric into several scales.

Meta-Rubric To Assess Our Rubric

The Chicago Public Schools web site lists the following criteria for evaluating scoring rubrics, which is criteria they have adapted.

* Does the rubric relate to the outcome being measured?

* Does it address anything extraneous?

* Do the criteria reflect current conceptions of excellence in the field?

* Are the dimensions and scales well defined?

* Is there a clear basis for assigning scores at each scale point?

* Can different scorers consistently apply the rubric?

* Can everyone understand the rubric?

* Is the rubric developmentally appropriate?

* Can the rubric be applied to a variety of tasks?

* Is the rubric fair and free from bias?

* Does it reflect teachable skills or does it address variables over which we have no control such as culture, gender or home resources?

* Is the rubric useful, feasible, manageable and practical?

* Will it provide the kind of information you need and can use effectively?

* Does it cover important dimensions of performance?

Value of Using Rubrics For Web Site Evaluations

We have included web site rubrics used by Adult Literacy and Technology Training Network and Blue Web'n to focus on the formal process of guided collaboration in the selection of web sites. (Internet version of this article).

There are obviously other groups who also adhere to a formal process by using rubrics and stated selection criteria's, which are not structured as rubrics but also serve the same purpose. Which is to provide consistency and integrity in selection of a web site to be included by the group or individual. A nother group is what are called collectively as rated web site award programs. Those who are members of an award program rating service or index, adhere to codes of conduct, listing requirements of each group and have a formal selection process which involves a published set of criteria, a mission statement and staff to help in selections.
