The rater takes a piece of writing and either (1) matches it with another piece in a graded series of pieces or (2) scores it for the prominence of certain features important to that kind of writing or (3) assigns it a letter or number grade. The placing, scoring, or grading occurs quickly, impressionistically, after the rater has practiced the procedure with other raters. The rater does not make corrections or revisions in the paper. Holistic evaluation is usually guided by a holistic scoring guide which describes each

A spark timer is connected to the apparatus so that as the bob drops a tiny mark is burnedon a waxed paper tape at 1/60 second intervals. Position-time data was used to determine theaverage velocity of the falling object in each prescribed interval of time. Students then plotted,by hand, a graph of average velocity of the falling object versus time. From the slope of the linestudents were able to determine the acceleration due to gravity. Students who received laboratory instruction using interactive digital video techniquesperformed this same experiment to determine the acceleration due to gravity.

These tests assess mathematical, logical, and word usage skillsto determine intelligence. It wasn’t until 1983 that Howard Gardner, a Harvard psychologist,challenged the concept of a single measure of intelligence. He proposed a broader definition ofintelligence which included the existence of at least seven basic intelligences, all of which wouldfocus on the capacity for problem solving and fashioning products in a context-rich andnaturalistic setting.

We can thus represent the downstream side as a connection to the zero potential forthe effort variable, which is migratory pressure. Representation of the upstream side of the valley could be one of three possibilities:1) A capacity element. Using this element would signify that the number of migrating animals is finite, whatever could be stored in the capacity element. Flow of animals from the element would decrease as the migratory pressure, and the number of animals upstream, decreases.2) A pressure source. Using this element would signify that the migratory pressure of animals attempting to

This “call to change” has not been limited to the educational community as various industrieshave carried out a variety of reorganization, downsizing and merger attempts in order to remaincompetitive. Some of the techniques used in the business community are now finding their wayinto institutions of higher education. Two of the most notable are reengineering and total qualitymanagement. Both these processes call for higher education to “go about its business” in a newand more effective way.

This external reference,16 MHz, can be divided internally by any factor from 1 to 16 to produce the internal shiftregister clock, which becomes the bit rate for the video data. The factor chosen determines theresolution of the display along a scanline of the CRT, In a standard CRT display, scanlines aregenerated with a frequency of 15 KHz to 16 KHz, which yields about 65 µsec for eachscanline. Generally 10% to 20% of this time is not available due to overscan of the monitorand required retrace time, so typically one can count on about 50 µsec of usable time on eachscanline for image generation.

It is time to assess our positions regarding whathas been accomplished and where future efforts might need to be applied.Here are some of our accomplishments:1. A significant minority of faculty have accepted biological engineering as their discipline. My assessment is that this group may have reached majority in some places, but that the largest group of faculty are those who have accepted the change to biological engineering as an experiment without final results as yet. They remain somewhat skeptical, certainly unenthusiastic, and have yet to accept where they will fit into the new discipline. The committed biological engineers

The Engineers' Council for Professional Development say that"Engineering is the profession in which a knowledge of the mathematical, physical, [social andpolicy] sciences gained by study, experience and practice is applied with judgment to developways to utilize, economically [and ecologically], the materials and forces of nature for the benefitof mankind."(1) Words in brackets were added in a proposed revision of the
