      I thought it was normal to actually *build* circuits in electrical engineering since my school required it. It wasn't until after graduation that I talked to other recent graduates and found out that my school had been the exception and not the rule. It certainly helped me get a job when I could refer to specific problems I had designing and building say, a 100W audio amplifier (just one of many projects), rather than just talking about the theoretical aspects of such a design. I also discovered that my school held a high reputation in industry because of this. Unfortunately, due to budget cuts and a the retirement of a few key professors, it looks like they will (or possibly already have) abandoned many of these hands-on labs.

      I took E.E. at Purdue in trhe late 60's and early 70's. The students were constantly asking for pratical applications for semester after semester of obscure math they were doing but getting little but promised o "that comes later"..... There was a story told of one Purdue EE grad who went to work and got a job designing military walkie-talkie radios. He designed a circuit that would work fine in theory, but fortunately someone else caught the problem before they started building them. He had done all the math fine, but one of the parts he calculated was needed for the walkie-talkie was a 1 farad 600 vold non-polar capacitor. Having no experience with actually building things, he stuck it in the circuit design and continued on. Back in the days this was done, such a capacitor would have weighed many times more than the soldier who was expected to carry the radio.

      Sadly, i don't find this funny. I'm a current EE student, going into my 5th year (i co-oped). We're on semesters, btw. Math is way too focused upon. Sure, it's cool, but 3 semesters of Calculus that we NEVER use, only to get to Differential Equations that we ALWAYS use. Personally, i think math/physics (i had to take 3 physics classes) classes could be condensed into 4 semesters, and improved, in focusing on matrices, and DE. And, i've talked to EE students from other schools (purdue included), and the programs are quite similar.

      What the problem is, is that during the Dot-Bust, everyone focused everything on computers. Sure, i like computers, they're great. But if i wanted to be a computer engineer, i'd go into Computer engineering. Alas, EE got so focused on computers that it really lost its overall focus on electricity, and its applications. And, when designing IC's, the work is almost all math. Blah.

      Some things that are lacking in EE: Motors of any kind, a focus on Controls, Real life transmission lines, rather than all microstrip lines, and more early EE classes. We didn't start circuits until Sophomore year. True, my university is changing the program, but this is a widespread problem that needs addressed in order to keep the world supplied with competent Engineers.

        Funny, I used to say that when I was a student. What the heck to you really use Laplace transforms for I asked? Later in digital signal processing class as I was designed filters I found out.

        Surely nobody really uses complex analysis - I mean, what do trig functions of complex numbers mean? Later in grad school studying electromagnetics, I found that wave reflection/refraction with complex angles meant attenuation for the refracted wave, and it was a way to handle polarization of all waves involved.

        Humph. No way would I use conformal mapping... until I found myself mapping the integers onto a circle in order to solve a potential distribution.

        Aha, I know there isn't any real use of integration in the complex plane. I mean, tracing out paths and detouring around zeroes, slices and branches? One lecture started up with that exact chart, solving some antenna radiation pattern by integrating from negative infinity to infinity along the complex plane. I was lost ... and I never again asked "what possible use is this mathematics that I am learning"?

      As a recent (less than 1 month ago) EE grad from a top school, I have to say that I think this desperately needed.

      Right now it is possible to get a degree in EE without ever having picked up a soldering iron. Theory is important, but we're not talking about some shitty school here. Of course MIT is going to teach their students the theory.

      Let me give you some examples here:
      • My last semester I was taking EE488: RF Circuits. Our final project was to build a DDS. Out of the four students in my group, I was the only one with any clue how to use a spectrum analyzer. Out of that entire lab section, our group was the only one to use the spectrum analyzer, despite a project requirement that you couldn't proove you met, unless you did (or perhaps did something really creative).
      • I was also finishing up a project for a VLSI course. Our chips had come back from the foundry, and it was now time to test them. The prof. brought some logic analyzers in to the lab, and we had some Altera eval. boards we could use to produce whatever signals we needed. Better than 90% of the students had no idea how to use a logic analyzer, and no instruction was provided.
      • I also did an independent study last semester. I was designing a new development board for the microcontrollers class. It's a very simple board. The professor and I had originally batted around the idea of having the students build it themselves. No go. It would be a nightmare. I spent time that semester asking other students if they though they or their fellow students could handle it and every single one said no. Even if we taught everyone how to solder, there would still be an issue with them fixing any mistakes them made. It all comes down to this: most students don't have much experience prototyping their designs.

        IMHO, to be a real engineer, you need to understand both the theory, AND how to use it.

        There is a huge gap between paper and reality. There are all kinds of important details that need to be worked out when you're actually building something. Grads should have experience working out those details. Without it, they can be well suited to be researchers and academics, but not designers of things that someone is going to produce 100,000 of.

        There is a reason that the US higher ed system is commonly accepted as one of the best in the world and that is that many schools concentrate on theory allowing the students to innovate after they graduate.

        If they don't know how to apply this theory, all they're going to be able to do is create innovative new theory. A well-educated engineer should have an ample knowledge of the theory, AND how to use it is real-world applications.
    • Theory is nice but real-world experience is essential. Nobody wants a product that works only in theory. One of the most amusing things I watched was the other students in CS150 which, back when I took it, was a required course for both CS and EE students. You had to design and build small digital circuits. The pure CS track and the EE track students started out the same but there was a sharp split when they found the circuits they had assembled didn't work.

    So Jack rigged up a wall socket so that it was hooked to a battery instead of the house current. Then he gave the kid a knife and told him to stick the knife into the wall socket.

    This sounds like a good idea to me. As a soon to be 3rd year EE major, I definately think this is the way to go. All of my memories from basic circuit design classes are well...nonexistant. The classes were so boring and theoretical that it was pointless to go to class...so i didn't. Learning circuits from a theoretical standpoint is difficult and often times the math is more complicated than what you'd reasonably expect from university class (I remember a 25 page homework solution for a 1 week assignment - 10 problems). There is also a lack of practical applications being taught. There is only so many times you can apply Kirchoff's voltage and current laws and Ohm's law to a box of lines and numbers and still be sane. Looking at schematics that mean nothing to you all day is pointless. I know I would have been far more interested in EE if we were building a transister radio or something useful rather than just tinkering with simple low/high/band pass filters and verifying Ohm's Law. Granted these are worthwhile skills, but you don't get the full picture of electrical engineering from crappy textbooks.

    One of the biggest problems I've seen with EE grads, is that some of them don't have any real-world experience. Sure, they can tell you the noise characteristics for a carbon resistor, but ask them to pick a 1/2 watt carbon resistor of a given value out of a bin, and they can't recognize it. A lack of hands-on experience, in my opinion, leads to them coming up with bad designs - either unworkably over-precise, or using non-standard parts, and so on.

    While understanding theory is important, it's only half of the job; if one doesn't have a way to apply it, they're only half-educated.

        If your "optimum solution" design doesn't work in the real world, it's useless. An EE should be able to produce a (final) design that works and meets specifications. Period.

    More lab time is a good idea. Touring factories, I'd expect, COULD be useful if the tour is targetted at 1st year EE students and isn't just some lame "look, we make stuff, isn't this cool" deal. Famous professors are probably worthless.

    But back to the lab - absolutely essential. When I went to school at University of Illinois, and I believe this is still the case, all first year EE and CompE students have to take a freshman lab class. At the time the class project was to build a car (the digital logic and sensor portions thereof mostly) that could navigate a course consisting of white tape on a black surface.

    In one semester, you started with simple logic gates and gradually built up something "useful" from those parts.

    If you were the kind of person who was able to and wanted to do digital things for the rest of your life, you liked that class. If you were the kind of person who did not want to do digital things for the rest of your life, or were simply unable to pull it off, you hated that class and switched majors before investing thousands of dollars in a major you ended up hating.

    For those who kept on with their EE/CompE, it was a great "frame" for the rest of the education - most things after that you could say "yeah, I can see how this is actually useful somewhere".

    And it also prevents having lab-newbies show up in 300-level lab courses - a big drain on instructor and fellow group member resources alike.

    If MIT hasn't been doing this until now, I'm only happier I didn't waste an extra $120,000 going to school there.
    • Famous professors isn't automatically worthless. Being famous does not keep them from being poor teachers. That's very true. But when the professor is a good teacher and in the back of your mind you're thinking "wow, this guy won a Nobel Prize." you may pay slightly better attention.

      For your information, the focal length of a spherical mirror is half the radius of curvature.

      In defense of the curriculum for your optics course, understanding the electromagnetic theory of light is vital for understanding the intersection of electronics and optics (fiber optic communication, lasers, photosensors, etc). In most of these equations, many of the same approaches used to analyze microwave and radio can be used, it's just that the wavelength is much shorter. In the case of photolithography, electromagnetic wave theory is needed to determine the resolution of an imaging system like a projection system for photolithography, which in turn limits the feature size. The theory behind this is directly analogous to the theory explaining the resolution limits of radar. To be honest, ABCD matrices and lens equations and such don't really need that much coverage--maybe a week or two of lecture and a problem set or two to get familiar with using them. If you ever need to use the ABCD matrices or lens equations, you can always look them up.

      If you really want to learn lens design or otherwise specialize in optics should go to schools like my alma mater [arizona.edu] or possibly our intellectual rival. [rochester.edu]

This is analogous to a doctor graduating without ever touching a patience while at school - would you want to be looked after by somebody that just used text books and computer simulations?

No, they describe a multiplicity of different ways of doing things and write text which is basically a fairy story to describe how and what it does.

    There are an awful lot of comments poking fun at MIT for some perceived paradigm shift - moving from theory to practice. But that's missing the point.


    I got my EE degree from Boise State University, hardly the technological powerhouse of MIT's caliber, but one thing that concerned the faculty in the College of Engineering was the need to not just attract students who wanted to major in engineering, but also to retain them once they started the program.


    It doesn't take a rocket scientist (or an engineer) to realize that two years of core engineering classes full of theory, math and seemingly non-applicable ideas is pretty damn boring to an awful lot of people. Although you may disagree, I think that it is not just important, but critical to see some sort of practical engineering examples. Sure, I got a lab with my physics class (I made a telescope, charted magnetic flux lines and measured acceleration, etc.) and there was a chemistry lab (oh boy, we made Slime). There was even a rudimentary circuits lab that taught us something about discrete passive devices. But the one class that was the "hook" that worked to cause most of the borderline (as in not sure if they want to continue in engineering) students to keep on was the Introduction to Engineering course.


    This was a course that featured a topic from a different engineering discipline each week: Electrical, Civil and Mechanical. The one hour lecture by a different professor from the field each week was followed by two three hour labs of projects related to that topic.


    Sure, we were just taking Calculus I at the time and no, we didn't know Kirchoff's laws. We couldn't describe a system with differential equations, but there are a ton of things that a student can do that involve intuitive engineering knowledge that don't require any more science than simply understanding how something works - not why it works...that comes later.


    At the end of the semester, the "capstone" project was, as I recall, a car that had to navigate away from obstacles using IR sensors. Yes, a lot of stuff was prepackaged, but the experience was valuable in that it showed the application of ideas and served as a way to tide us over those first couple of years when hours of math, physics and chemistry threatened to send us all screaming down the halls.


    I should point out that, at least at Boise State, the College of Engineering has a very high graduation rate. I don't recall any EE student who started their freshman year with me who didn't go all the way to the end and graduate. Obviously there is a lot that goes into a high graduation rate, including the dedication and determination of the student as well as the quality and committment of the professors, but it seems to me that something works at BSU.


    Also, every one of those graduates who took the Fundamentals exam (a prerequisite for becoming a Professional Engineer) passed. Did EE120 make the difference? I can't say, but I do know that it was one of the courses that I took that really sticks in my mind because it showed early on that the things that we were learning and were going to learn had practical applications.

    Disclaimer: I have tremendous respect for Hal Abelson and Gerry Sussman, having worked with both while teaching the MIT EECS core undergraduate curriculum, including 6.002.

    The article glosses over a couple of details which are important to understanding what Abelson and Sussman are proposing (as evidenced by many of the comments thus far). The course, 6.002 [mit.edu], is already a laboratory couse with required lab assignments. However, there aren't that many (4 or 5), and while one's lab grades are important, it is possible to pass the course (*pass*, not do well) without doing well on the labs. The course is reasonably heavy on theory, and somewhat light on practical knowledge. When I was TA-ing it, I was amazed at how many students did not already know how to solder.

    For many students, it was the first lab course ever, so things like oscilloscopes were poorly-understood tools. (As part of the first lab assignment, if I recall, one must prove proficiency with a 'scope.) As a result of this, many of the students don't really get a good understanding of basic parameters and values -- practical knowledge -- because there's so much to learn already, and because there are only 4 or 5 lab assignments and only so many lab TAs.

    What Abelson and Sussman are trying to do (and, by the way, they are the authors of what is widely considered one of the best, if not the best, course at MIT, 6.001) is shift some of the tutorial instruction, typically centered on going over lectures and recitations in more detail with an eye towards the homework assignments and similar problems, towards understanding specific real-world problems. They are, in effect, changing the syllabus where it has been previously poorly-defined, and where the student-to-faculty ratio is the lowest, so it can do the most good.

    (For those not familiar with the way such courses are structured, there are some number of hundreds of students per term taking the course, and three levels of instruction: twice- or thrice-weekly lectures by senior faculty to the entire class, supplemented by twice-weekly recitations by junior faculty or senior graduate students to sections of 15-30 students, supplemented by once-weekly tutorials by junior graduate students to sections of 4-8 students. This is a well-developed and powerful means of teaching a huge amount of difficult material in a short amount of time to highly-motivated students.)

    It will be very interesting to see how 6.002x develops. Very interesting. Might just go and volunteer to help teach next term right now.
