What’s Wrong With Engineering Education?

How to Fix Things

In my talk at the conference, I suggested a list of changes I would like to see in courses. One of the professors summed up the situation with, “Lou, those kinds of changes scare me to death. You are probably right but we will not be changing anything soon.”

First, we need more lab work. Over the years, colleges and universities seem to have cut back on actual hands-on lab work. In some cases, it makes sense as the way engineers design today relies more on computer-based work like math analysis, automated design, simulation, verification, and so on.

There is less breadboarding and more validation by computer. Yet engineers on the job design and build hardware. It seems like there should be more of a hands-on component to the educational process. However, labs are expensive, they eat up vast amounts of time, and most professors hate lab work and have graduate assistants do it.

Most students do get a decent dose of embedded controller and FPGA design, but so many other areas are neglected. Analog, RF, and wireless seem to have less labwork, and there is a real shortage of test and measurement knowledge. All of that gear is very expensive, but that is what students will encounter in industry. I’ve interviewed BSEE grads that could not find pin 1 on any IC, find the cathode on an LED, or measure the frequency of a signal on an oscilloscope. But, they could really use the computer and do high-end math.

The technology schools do a better job at more practical hands-on engineering—I mean engineering technology (ET) as opposed to engineering. Many schools offer a BSET that pretty much covers what is in a BSEE, but with a bit less math and science and more practical design courses. If you are looking for a new engineer that can hit the ground running in a lab, I recommend a recent BSET grad as your best bet.

Second, help retain students rather than weed them out. I see and hear this on a regular basis, especially for those who teach the early electronics courses. The goal seems to be eliminating students in the early circuit analysis courses if they don’t do well. Schools deliberately make the courses too hard to kill off a huge percentage of students who want to be EEs. The result is fewer engineering graduates.

I can’t help but feel that doing more to aid retention of current students will boost the number of graduates more than external recruiting efforts. Yes, I know that some of those students who are weeded out probably should be, but not all. Most just need a little more help or time. Again, this is either an attitude problem or bad teaching. Professors don’t want to give that extra time and feel that if the student can’t make it so be it. Goodbye and good riddance.

How many students who really want to be EEs would be saved with a little more help and a better attitude from professors? Note to professors: Your goal is not to weed out; it is to help students learn. Why not try to save the students instead of dismissing them? Or could it be that you are just carrying out some higher-level policy at the institutions to limit enrollment for lack of funds?

Next, there’s a mixed picture when it comes to textbooks. All of the major publishers were at the conference, of course. There are many textbooks available for most courses. And there are some smaller publishers now addressing some of the niche or more exotic areas that the larger publishers won’t touch.

The big publishers work from a business model that thrives on high volume for profit. With declining enrollments and more specialized subjects, that volume will never occur. Yet a good book is usually necessary for a course. Thankfully, the smaller publishers seem to be addressing all sorts of these low-volume needs.

I also saw that many basic texts have not been changed in years. Again, I know that the basics do not change, but they could be presented in a way more suitable for the current technology. And many still emphasize the wrong topics or omit newer technologies. For instance, many books still teach you 1001 ways to bias a bipolar transistor while the industry has moved on to predominantly MOSFET design by software. Many texts still seem to omit switch-mode power supplies when most of the electronics gear today is predominantly switch-mode.

Another observation is that no one from industry writes the texts. I wish they would, as we may get a more practical, real-world feel for engineering and design that is missing in the books written by faculty. Given that we could get industry authors, would the faculty adopt new books?

And when are we going to get textbooks by the chapter as publishers have been promising for years? A few will do this if the volume is good, but otherwise, no. Again, it is a money/profit thing. I bet many professors would love to cherry-pick a book and use only what they want and need.

Also, publishers should push on through and give us electronic books—whole and chapter by chapter. They would be cheaper for students, and faster and easier to update. Most students were brought up with the computer and don’t mind reading from a screen. It is what this generation does. Excellent e-book readers and lower prices show that it is time.

Furthermore, no one mentioned continuing education at this conference. It used to be a hot topic in industry and academia. Did we abandon it? Industry hates to support it because it costs dollars and time, but it would benefit from bringing engineers up to speed.

Continuing education is an often indirect and long-term benefit, but technical obsolescence is a certainty and comes on you faster than you perceive. All we need is for the institutions to offer more courses geared for continuing education purposes. Price them right and you will get some industry participation.

In talking to some engineers about continuing education, most say the same thing. If they need to know something, they just Google it, and voila, instant knowledge. There’s big-time truth in those comments, but you do not always get the depth you need. It’s no wonder continuing education faded away. That point of view, more than ever, highlights the need for colleges to teach their students how to learn.

Finally, schools need to quit teaching the history of electronics, update their programs, curricula, and courses, and get more industry input. Meanwhile, industry should get more involved. So many of you in industry are afraid of academia. But in most cases, you know more than they do. They assume the ivory tower position, but only you industry people know what is really needed today.

Additionally, the accrediting bodies should give more credence to real industry experience over academic credentials. Even people with PhDs don’t know it all or even what’s best. Neither does a degree ensure that a person is a good teacher. That PhD grad is mostly academic, with a very narrow focus on some research topic that is not applied. It is the applied part that is missing in engineering, which by definition is truly an applied discipline. I’d rather have a student taught by a smart MSEE with industry experience than a PhD with little or no real experience.

Try to remember that not all EEs are alike. There is more than one type or level of engineering. Those who do go on for graduate work and the PhD need somewhat different courses to support research and greater subject depth than those who just want to do product engineering, test engineering, or manufacturing. A one-size curriculum does not always fit every job out there. Adjust accordingly.

Okay, so I have been critical, but it is needed. I can defend my opinions, as I have been a professor and have seen how it is. And I still teach as an adjunct professor every now and then. But that said, I do think that despite their faults, American institutions and faculty are still the best in the world. They could improve their efforts, however, at staying in tune with the industry they serve.

We need a strong educational system to keep this country in the forefront of technology. The institutions need to be less self-involved and more outward-oriented. They say all the right things in altruistic verbiage but often do not practice it. Instead they focus on tenure, benefits, grants, political maneuvering, and other internal, self-serving efforts to the detriment of the student. Just prove me wrong.

    Well put, my friend. This is that dilemma I faced while attending college and has been a deterrent for me returning. In my experience I found that the R&D team, marketing dept. and "in-field" experience counts the most when it comes down to leading the Industry with new ideas and different techniques in Engineering. The Universities and its profs lag in this area via monotonous traditions making it difficult for advancement and improvement with updated material for us Engineers. This creates an issue. On a personal note, perhaps integration with the Industries and the Universities or greater exposure between the two should suffice this issue (advanced internship). Afterall, once educated we end up here anyway.

    Two stories related to this article:
    A number of years ago, we had a young woman who was taking course at our local community college toward an ASET degree. She would occasionally ask me for help with homework. One week, she asked me about problems related to calculating plate areas for capacitors. I was a bit surprised that they had spent a wek on this subject & I talked to the department head about how this was pretty much a waste of time, as the chances of ever having to do this in the field were vanishingly remote. He reolied that he didn't know that so much time was being spent on things such as this. He asked if I would be interested in being on the curriculum committe for the electronics program, and I said that I would be glad to participate, but despite two additional contacts with him, where I brought up the subject of the curriculum, he never called back. I doon't know what they are teaching up ther now.
    The second story was when we got a new EE graduate into the office as a tech/junior engineer, and I was working with him on som efairly basic circuit operation (bipolar transistors & comparators). At one point, I was talking about circuit operation and said that on thebase of a particular NPN transistor, we would expect to see about .65 volts. He replied, "How do you know that?" I then said that this was a pretty standard voltage for a silicon transistor - didn't he learn anything about that in school? His reply was that he vaguely remembered something from a long time ago, but he wasn't very familiar with it. It was obvious that he had spent very little time actually building & testing basic circuitry.
    I agree with "M" above (James Bond's boss, perhaps?) that colleges should be more active in looking for industry-experienced engineers to teach some of their classes.

    I returned to school late in life to get a BSEE. I started out at a community college and finished up at a well-regarded 4-year institution. I noticed that the community college was staffed by career teachers who were interested in the success of all of their students and in polishing their own craft. The administration backed them up with various programs to assist any students who might have difficulty. In contrast to that, the 4-year university was staffed largely by people from industry positions who were falling back on secondary occupations of teaching and did not seem particularly suited to the task. I should mention, though, that there were some notable exceptions--there are a few fine teachers there. The thrust of the first two years of the 4-year university was to weed out as many unsuitable students as possible--those who couldn't teach themselves--while in the Junior and Senior years students were shuttled on through to graduation. It seems to be that the universities could learn a lot about teaching by examining the community colleges.

    Interesting that in the liberal arts, it's possible for a prof to get time off to do research on Shakespeare, whose opus has not changed in centuries - but it's not possible in engineering, where things change by the minute.

    A tsunami of change in education is coming, no question. In ten years education will look radically different. The question is, will the change come from today's educators, or will it happen around them, leaving them to become tomorrow's typewriters and vacuum tubes? They aren't going to be able to maintain their position as gatekeepers much longer.

    I agree with your article wholeheartedly. I would add that there are quite a few engineers who have left industry - via outsourcing, early retirements, buyouts, etc. - but who still have several good years left. Quite a few of these industry veterans spent considerable time in front of large groups of people, explaining how a product/technology/process works, what it costs, why you need it, and so on. Sounds something like teaching, doesn't it?

    So, could we get the industry angle into the classroom by hiring some of these engineers to teach college classes? Could we make the working environment attractive so they'll accept the relatively (ridiculously?) low academic salaries. Could academia can live with faculty who don't (gasp) have PhDs or even (horrors) an MS. Hmm, probably not.

    Sounded good for a minute there.

    Co-op/internship programs are an excellent way to help address many of these issues. Industry experience helps students understand what they are learning in school can be applied in the real world. It doesn't replace the other excellent suggestions made in the article, rather it enhances them. This is area where industry and universities can work together to improve the quality and quantity of opportunities for students.

    I have a very skewed opinion of Institutions of "Higher" Learning in general. A Va Tech professor described the current University atmosphere as "Beer and Circus". This practice of encouraging poor study habits and distracting students while accepting their tuition added to "sorting tools" i.e. higher mathematics, are used to weed out students so that the number continuing on into the last two years and towards a degree don't exceed a number requiring more teaching staff. It isn't the Universities plan to graduate more students. As noted in your article Professors are about obtaining grants for their department and building their resumes not about teaching classes.
    When approaching your suggestions for correcting the situation through the above (skewed) point of view it makes perfect sense to me why it isn't changed. There's no money in it.

    Good article. Add too, most protocols for communications, like HDTV and MP4, have become taboo in grade schools, hijacked,"privatized", and secret. "How to" books and kits for microwaves, radio, etc. are not likely to show up on Hanna Montana (but why not). And nobody is out to create motivation or lower entry cost for hobby electronics. A ten dollar programmer for PIC processors should be the beginnings of a cap bomb, rocket, robot, and spy radio in the driveway of every urban nerd in the US. And the 16F84 should cost 10 cents and run at 100Mhz, not be "deprecated". And every toy whiz bang or alley rocket should have an onboard HDTV microcomputer transmitter. Show me that weather station/toaster/aquarium/paint gun/rc car, etc.with that HDTV microcomputer remote control display. Instead we have snake eyes, people so blind, greedy, and gutless that they have to double check their DARPA zipper before every first order differential equation. D1=D1+D2*DT
    One Chinese company with a fast FPGA and a sense of home-boy, and for the US, it's game, set, and match. Like doctors, the problem is not government control but lowering liability cost, lowering generic chip cost, and national efforts to create and promote simple RAD interfaces, open codes, and new markets. Estimates are that a robust hobby HDTV transmitter can be made for 2$, instead we have frozen the market at about $4,000!! Just a thought.

    Seems like you're confusing a vo-tech technical program with an engineering program. Teaching current parts or languages guarantees obsolescence in short order. Teaching concepts, and fundamentals allows for understanding of new technology as it is developed. Case in point, oscilloscopes are becoming obsolete with new high speed serial busses, you can't just tap into the net and expect to see any sort of clean edge, only at the terminated receiver on the die will the signal be undistorted. You cant drop a probe on HyperTransport, DDR3-1600 or PCIeGen3.

    You are absoultely correct. No professors is ready to update themselves as they may thought of increasing their workload. Yes,education should be upto latest technology with basics ...
