ENGINEERING CRITERIA 2000 PROGRAM CRITERIA

PROGRAM CRITERIA FOR

ELECTRICAL, COMPUTER, AND SIMILARLY NAMED ENGINEERING PROGRAMS

Submitted by The Institute of Electrical and Electronics Engineers, Inc

These program criteria apply to engineering programs which include electrical, electronic, computer, or similar modifiers in their titles.

1. Curriculum

The structure of the curriculum must provide both breadth and depth across the range of engineering topics implied by the title of the program.

Graduates must have demonstrated

knowledge of probability and statistics, including applications appropriate to the program name and objectives;

knowledge of mathematics through differential and integral calculus, basic sciences, and engineering sciences necessary to analyze and design complex devices

and systems containing hardware and software components, as appropriate to program objectives.

Graduates of programs containing the modifier "electrical" in the title must also have demonstrated a knowledge of advanced mathematics, typically including differential equations, linear algebra, complex variables, and discrete mathematics.

Graduates of programs containing the modifier "computer" in the title must have demonstrated a knowledge of discrete

mathematics.

ABET 2000 http://www.abet.org/eac/eac2000.htm

GONE are dozens of pages of specific requirements

New, very brief, outcomes-oriented criteria– do not require any courses in a math department– do not prescribe specific syllabi and manual skills– emphasize teamwork, technology, applications– emphasize assessment - improvement cycles

ABET 2000 looks a lot like MSE reform -- there is a major difference: ABET has teeth that bite, NAS-MSEB does not, NSF DUE carrots are small compared to ABET’s teeth.

The Foundation Coalition

The NSF, ABET, …. are dead serious. The FC alone is to receive 30 Mill. $ from the NSF over twice 5 years.And the FC is only one of 6 original coalitions, most refunded for second 5 year term. (Compare calc reform?)

2nd engineering freshmen projectThe “bungee omelet drop”, due week 13 of first semester!

“The goal of the project was to design a bungee cord that would allow a payload, in this case, an egg, to come as close to the ground as possible without damaging the payload. The egg was to be dropped from ASU's Sun Angel Track Stadium's bleachers. Damage to the payload could have been incurred in one of two ways. First, the payload may be damaged by hitting the ground. Second, the pay-

load may be damaged by decelerating too rapidly. Freshmen mathematics?

A first semester team project, due in week 13:

Model the free-fall / elastic stretch including dampingcalculate, optimize, design release mechanism...Objectives: Longest possible free-fall , as close to the ground as possible, constraints on max acceleration

Engineers INTEGRATE the nonlinear, second order,only piecewise smooth, DE no matter whether math delivers or not -- use EXCEL in the first semester for what math usually barely delivers in the fourth semester.

“Design”A small, but crucial modification of a traditional application:

The traditional “physics” problem analyzes rolling objects on an inclined plane. It goes as far as asking which object will win the race (compare: D. Drucker’s “Mathematical Roller Derby” in CMJ 11/1992). The calculus link are moments of inertia, i.e. iterated integrals, and a simple separable DE. The problem solution never goes beyond the level of “analysis”.

PROUD winners and winning design

The “engineering” problem goes one,CRITICAL STEP further: We ask thestudents to “apply” the knowledge gained by DESIGNING and BUILDING a rolling object that will win a race in the class!

The results are amazingly fast: Further useof calculus yields an optimal design with J=0.08 ma2 as opposed to J=0.40 ma2 for a solid billiards queue ball!!!

Or, sometimes it takes onlyfairly small changes to give a standard math topic a marked engineering twist…..

What level of math?

Use technology -- no time for hand manipulations.

Theory matters! Theory matters!

Current research -- not just 300 year old stuff!

Traditional emphasis, physics point of view:Conservative ( = integrable ) vector fields,“closed loops lift to a potential surface”

Modern emphasis, engineering point of view: Controllable ( = nonintegrable ) vector fields, “design the closed loop in base so that the vertical gap of the lifted curve is as desired”.

CrdF

Traditional: Given F and C find (boring w/ computer algebra system)Modern: Given F and find C (intelligent, ubiquitous applications)

“And where did the integration techniques go?”

• Very disconnected debate:math/engineering old-timers those preparing for ABET 2000

• Need to set priorities! Better stay close to ABET 2000!

• “Prepare for the next course” is no justification• Professional engineers don’t have time to integrate by hand

they use computers for both reliability and efficiency ($$).

• Isolated knowledge is useless --

must be able to APPLY the knowledge to solve “problems”.

In case you wondered: We do have basic-skills “mastery tests” using JohnOrr’s O-Line Testing System)
