In a week I will begin teaching an entry-level class that the local
radio club is offering. I would love any words of wisdom from experienced instructors of this material. I suspect that it has been at least a couple of decades since I last taught such a class, and things have changed a bit in that time grin. The basic issue I'm wrestling with is walking the tightrope between teaching the actual questions from the pool and teaching concepts. It's not fair to the students to ignore the existence of the pool; after all, one of the goals of the class is to prepare them to take the written exam. But another goal is to get them ready to actually be an active member of the ham radio community, and memorizing pool questions doesn't contribute to that objective. So I'll try to do both -- cover concepts and review the actual questions. Another issue is the scheduling of the class. There are proponents of the weekend method -- cover the material in a day or so. While there are advantages to that, I favor multiple shorter sessions. I think that learning is much better in that environment, but in today's hectic world, getting people to commit to multiple sessions is problematic. We've decided on six session spread over three weeks. Maybe that was a fatal error; time will tell. I wish we still had something like the Novice license. I'd like to be able to get past the pressure of the written exam and get prospective hams some real experience so they understand what I'm babbling about in class. For example, you can lecture about repeaters, but if the students have actually *used* a repeater, they have a whole different understanding of what you're saying. 73, Steve KB9X |

Handouts are a good idea too, as are links to specific web pages. Another thing I suggest is demos. Talking about repeaters is one thing, working somebody many miles away using a handheld is another. But don't limit the demos to VHF or FM - just showing things like PSK31, CW, etc., are a good idea. For example, you can lecture about repeaters, but if the students have actually *used* a repeater, they have a whole different understanding of what you're saying. Hence the demos. Keep in mind that the Element 2 written test used to be the written part of the Novice test. I don't think that's true. Not anymore. Before the 2000 restructuring, the written exams were these: Element 2 - Novice Element 3A - Technician Element 3B - General Element 4A - Advanced Element 4B - Extra Each element required its own element plus all lower elements. As part of the 2000 restructuring, the elements were combined: Old Elements 2 and 3A were combined and renamed new Element 2, used for Technician Old Element 3B was renamed new Element 3 and used for General Old Elements 4A and 4B were combined and renamed new Element 4. Arguably, it is easier to get a no-code Technician license than it was to get a Novice license. Agreed - which sealed the fate of the Novice, by making Technician the de-facto entry license. Please understand: I am not complaining. I think that is a good situation, especially if the intent is to draw newcomers into real-world communications, like disaster relief and not the self-limited exchange of beeps that the old Novice class was offered. I disagree! The old Novice offered a lot more than "the self-limited exchange of beeps". The old Novice wasn't meant as a permanent license class, but rather as a training ground towards the higher class licenses. Yes, the privileges were limited, as was the license term. But what that did was to focus newcomers on a few bands and radio basics. It also reduced the cost of getting started. Many Novices built their first stations, or part of them. This was practical because the limited priviliges meant that even a simple, low cost station was competitive with what other hams in the Novice subbands were using. But those days were ended by the Tech becoming the entry point. Not many new hams can build an HT as a first project! IMHO, the ideal 2007 entry-level license would offer a variety of bands and modes. 73 de Jim, N2EY |

I have limited expectations that the attendees will spend vast amounts of time studying outside of class, and frankly I rather hope that that time will be spent taking practice exams. I think it's unrealistic to expect that if I "assign readings" anyone will actually read them. Then, you give a test that covers the outside readings as well as the lecture content. You could use the question pool as outside reading material and then lecture about actual practice. Difficult questions from the pool could be covered at the end of class as an "extra help" session. This would be a fine strategy if my primary goal were to teach concepts, but my primary goal is to get these students a passing grade on the test. Sorry, but that's just the way that it is. I don't think it's appropriate for me to teach actual practice to people when they first need to pass their written exam. What I would *like* to do is teach a followup class on what people need to know to get on the air -- how to select equipment, what actual antennas are like, operating procedures, and so on. But I simply cannot do that *and* teach them enough to pass the written test in the amount of time available. I consider my first priority getting them past the written test, then we can work from there. I have to add, and I don't want to sound condescending, but I know that some of the people who will attend this class are barely literate, much less capable of reading and understanding the question pool . . . even though it's written at a junior-high level. This may be another challenge that I have -- how can I keep the intelligent people in the class interested when the dumber-than-a-rock crowd doesn't even understand the concept of what a frequency is? Keep in mind that the Element 2 written test used to be the written part of the Novice test. Uh, no. Arguably, it is easier to get a no-code Technician license than it was to get a Novice license. Different. Maybe easier, maybe not. Depends on how you learn and your educational background. The written test for Novice was trivial. I had no problem with it when I was 13 years old. I also had no particular problem learning code when I was 13 years old, but the theory test for General class was quite intimidating. The Tech written is at least somewhat similar to the General back then. Please understand: I am not complaining. I think that is a good situation, especially if the intent is to draw newcomers into real-world communications, like disaster relief and not the self-limited exchange of beeps that the old Novice class was offered. Sorry, but the the Novice class offered a lot more than "the self-limited exchange of beeps". It was a true entry-level license with incentive to upgrade. (You can't get much better incentive than the license going away in a year.) You got a real taste for ham radio and a real understanding of what the additional privileges you would earn really meant. The Tech license is not an ideal entry-level license. It requires quite a bit of intimidating work to learn material that is pretty foreign to people who have no experience in radio. Once you've got the license you need someone to demonstrate the wonders of HF, else there is no incentive to upgrade. What I'm looking for is a real entry-level license, similar to the Novice ticket, with an incentive to upgrade. I want to be able to actually teach concepts and the real skills that people need to get involved in ham radio, without feeling that I cannot do so because my limited time must be spent getting them the knowledge to correctly pick answers to pool questions. But that's not likely to happen, so I'll do the best I can with what I have. 73, Steve KB9X |

Introductory stuff with links to more advanced things. This would be a fine strategy if my primary goal were to teach concepts, but my primary goal is to get these students a passing grade on the test. Sorry, but that's just the way that it is. I don't think it's appropriate for me to teach actual practice to people when they first need to pass their written exam. Then you're essentially "teaching the test". And with all due respect, that's a mistake IMHO. Here's why: I think that we hams have sometimes placed too much emphasis on getting lots of people licensed rather than educated and licensed. The result is folks who are licensed amateurs but don't really know how to get on the air. They're then left without the structure of a class, to learn what's needed to actually use the license. A recent statistic from ARRL said that 22% of new hams had *never* gotten on the air with their new license. To me, that's a direct indication of putting the license ahead of the knowledge needed to use it. What I would *like* to do is teach a followup class on what people need to know to get on the air -- how to select equipment, what actual antennas are like, operating procedures, and so on. But I simply cannot do that *and* teach them enough to pass the written test in the amount of time available. I consider my first priority getting them past the written test, then we can work from there. Perhaps the handouts could cover the practical stuff. If time is that limited, then IMHO its purpose is to guide rather than to be comprehensive. I have to add, and I don't want to sound condescending, but I know that some of the people who will attend this class are barely literate, much less capable of reading and understanding the question pool . . . even though it's written at a junior-high level. Who *are* these folks? I mean, the current written exams have been passed by elementary school children years away from middle school. I suggest that if you have low expectations, the class will live down to them, and if you have high expectations, they will live up to them. This may be another challenge that I have -- how can I keep the intelligent people in the class interested when the dumber-than-a-rock crowd doesn't even understand the concept of what a frequency is? With all due respect, if someone cannot grasp the concept of what a frequency is, they should not be a licensed radio amateur, IMHO. Such a lack of basic radio knowledge means the person just isn't qualified yet, and endangers both the person and those around them. The whole point of license testing is to insure that licensees know the basics. The Tech license is not an ideal entry-level license. Agreed. But it's what we've got. It requires quite a bit of intimidating work to learn material that is pretty foreign to people who have no experience in radio. I disagree. It all depends on how the material is presented. To use the frequency example, while most people might not know a kilocycle from a bicycle, they will probably know that a piano produces different tones. A simple electronic keyboard can demo that principle easily. Then it's a short step to different radio frequencies. Of course it must also be learned that there's a difference between sound as vibrating air and radio as a vibrating electromagnetic field, but that's part of the game. Once you've got the license you need someone to demonstrate the wonders of HF, else there is no incentive to upgrade. Why not as part of the frequency demo? How about a long roll of paper with various frequencies on it - 60 Hz for power, the AM BC band, the 49 MHz baby-monitor band, VHF and UHF TV, FM BC band, cell phones, microwaves, and oh yes, the ham bands. Color code it for the various services. What I'm looking for is a real entry-level license, similar to the Novice ticket, with an incentive to upgrade. I want to be able to actually teach concepts and the real skills that people need to get involved in ham radio, without feeling that I cannot do so because my limited time must be spent getting them the knowledge to correctly pick answers to pool questions. Then you need more time. It's that simple. The time can be class time, or it can be time the students spend reading and learning on their own. But it takes time to learn this stuff.

I probably shouldn't sell the students short until I see who actually shows up. That's a big part of what I am saying. But the impetus for the class was a request from a couple of people who have already attended two previous entry-level classes taught by the radio club in the next town over. I saw their material; it's good; anyone who managed to attend their class and not pass is either unmotivated or unteachable. I'm not convinced. Did you sit in on the classes and see what was actually presented? Were the students able to attend all the classes or only some? Good material, by itself, isn't going to guarantee success. I suggest that if you have low expectations, the class will live down to them, and if you have high expectations, they will live up to them. You have an excellent point, and I will try to act on it. Thanks On the other hand, I do have to be realistic. I have to adapt the material to the level of the people in the class, to the best of my ability and striving not to pitch it so low that part of the class gives up in disgust. That's true of any class, isn't it? Particularly one where attendance is 100% voluntary. With all due respect, if someone cannot grasp the concept of what a frequency is, they should not be a licensed radio amateur, IMHO. Such a lack of basic radio knowledge means the person just isn't qualified yet, and endangers both the person and those around them. I think you've gone too far because I went too far in my example. I stand by my statement. There must be certain minimum qualifications to be a licensed ham. That doesn't mean a high level, but it does mean all hams should know the basics of how radio works. Otherwise the whole purpose of the ARS is undermined. The students in this class live in rural Minnesota. Electronics is foreign to most of them. They can run a GPS-controlled tractor and cover their fields without double-spraying a single row, but don't expect them to understand the concepts of how GPS works. Or want to. I'm not saying they should understand GPS to a high level. But being from rural Minnesota doesn't mean they are incapable of understanding basic radio if presented properly. It's a real challenge to teach electronics to this demographic. For one thing, their motivation to learn the material is 100% related to passing the exam; they really couldn't care less that 1 amp will flow through a resistance of 1 ohm if 1 volt is applied. They don't have to *like* it, they just have to know it. Some of it I can make "real" -- bring in a long extension cord, measure the resistance, discuss what that means when you put a welder at the end. BINGO! That's exactly it - tie the seemingly-abstract theory to a real-world practical example. Another would be a demo of why short thick jumper cables are better than long thin ones. I can tell you from personal experience that most of a teacher's job in such situations is finding an explanation that can connect what the student already knows to what is being taught. Most of these folks will never be electronics gurus. They don't need to be. They need to understand enough concepts to understand how to operate the equipment that they buy. Agreed. The license tests are the starting point, too, meaning the person who passes them has met the *minimum* qualifications, not that the person is an expert. Do they need to understand the relationship between wavelength and frequency to do that? Yes! (IMHO) No. Sorry, that's one of the most basic things about radio there is. All it really requires is an understanding that low frequency = long waves and high frequency = short waves. The whole point of license testing is to insure that licensees know the basics. I'm not sure that's actually true. Why do we care that a Technician licensee knows Ohm's law? Because it's basic to the operation of radio. Real world example: There's a lot of electronics out there that requires a certain minimum voltage to work properly. Typically 11.5 volts or so for "12 volt" equipment. Some things, like camcorders, have automatic minimum voltage shutdown. Most ham gear doesn't have such protection. At least some amateur transceivers will emit spurious signals if you try to transmit with them using too-low supply voltage. Synthesizer unlock and similar stuff. Spurs that can cause interference to other radio services. On top of that, most rigs draw a lot more current on transmit than receive. So if our new Technician doesn't understand Ohm's Law in at least a very basic way, s/he could hook up their rig using wire that has too much R, and then transmit all kinds of spurs because the rig is getting too low a voltage on transmit. Yet it will receive perfectly because there's enough voltage when not transmitting. Indeed, the ham could even start a fire by overheating the power supply wires. It seems to me that the point of license testing is to erect a barrier to entry. If that were not the case, the license pool would look a lot different. It would consist of regulations and practical knowledge that was actually used on a day-to-day basis. It would consist of material that, to use your phrase above, is essential to insuring that the licensee is not a danger to the person and those around him. Ohm's Law isn't just theory. An understanding of it is a practical necessity for radio amateurs. Otherwise they're not qualified to do what the license allows. Then you need more time. It's that simple. The time can be class time, or it can be time the students spend reading and learning on their own. But it takes time to learn this stuff. But I don't have more time. Doesn't have to be *your* time. It's going to be hard enough convincing people to come to six sessions spread over three weeks. If I asked for more time, I would get no students. How do you know? The goal is to figure out how to best use the time I have. If I'm really successful, I will be able to lure people back to a followup class. That's the only way I'll ever get access to more of their time. At a certain point, they have to be interested enough to invest the necessary time and effort. "If it were easy, everybody would do it." And we're back to the concept of the exam as a barrier to entry. No. It's not about "barriers". It's about a ham knowing the basics. If you have zero barrier, you have CB. I would phrase it as "zero requirements". But yes, you have cb. And look how that turned out. Should amateur radio become nothing more than high power multiband cb? I say no. If you have infinite barrier, you have no one entering. Of course, but the license requirements are far from infinite. They're just the basics. 73 de Jim, N2EY |

If you have zero barrier, you have CB. If you have infinite barrier, you have no one entering. Like everything else in life, this class is a series of trade offs. I picked six two-hour sessions as a compromise between having enough time to cover everything I want to cover and being able to attract enough people to conduct a class. I'll trade off time covering concepts to time covering specific pool questions since I owe it to the students to cover both. And I'm sure I'll be challenged to keep it simple enough for some students while trying to challenge the rest. 73, Steve KB9X I never got a class for my novice license thirty years ago. I listened to a lot of code on a shortwave radio in the parlor of a church's community building and practically memorized an ARRL publication entitled "How to Become a Radio Amateur" if I'm remembering correctly. And even though I'm an electrician by craft let me assure you that there is not a lot of theory to electrical service work. The only time I've needed ohms law is for long outdoor feeders but I was ahead of the other apprentices when I learned about feeders because of amateur radio. I let my novice license lapse because I moved to an apartment and could not have antennas there. So back in January my Fire Chief calls me aside and says since you've been training the Community Emergency Response Team volunteers and studied up on disaster preparedness I want you to represent the department on the cities Disaster Preparedness Committee. My work on the committee showed me that the local government could not afford a lot by way of communications for disaster response work. The only likely source of help we could identify was amateur radio. I new there had been a lot of changes in the thirty years gone by so I took the technician class given over two weekends in February of this year. One of the things that the instructors showed us was some home brew antennas. After passing my exam I tackled a collinear J-Pole as my first home brew antenna because I could afford the tubing a lot easier than I could afford any of the ready made antennas that claimed a similar gain. I bought a used SWR meter, a club member checked it against an antenna analyzer into a club antenna, and using only that SWR meter and some patience I adjusted the J-pole to an acceptable SWR. A used Yaesu FT470, Mirage BD35, and that J-pole, and I'm working a fair number of repeaters, participating in the local EMCOM training net and working every public service gig I can. I can't build a radio yet, but I have been praised for my work on the events by people who have no reason to butter me up. I got to try out HF at the Get On The Air table of the clubs field day in June and the list goes on. I think I'm getting an awful lot of mileage out of that two weekends. I know I'm rambling but don't sell your students short. If you put the effort into preparing a lot of show and tell, using real world examples they may surprise you with how much they learn. Some of what they learn you may never be aware of but the stuff I learned out of ARRL books is still helping me feed my family. The material they put in the effort to present during those two weekends back in February is helping me to learn to help my community if the stuff ever does hit the fan. -- Tom Horne, W3TDH "This alternating current stuff is just a fad.
