I question how the question pool is so much worse of a learning tool than say a book. Depends what you mean by "better" and "worse", Mike. Here's something to try. Let us take a website: http://www.ewh.ieee.org/reg/7/millen...scientist.html This is IEEE's write-up on Reginald Fessenden. Let's take a situation where there is a question on the first date of transmitted sound. Quoting from the page: Professor Kintner, who was working for Fessenden at that time, designed an interrupter to give 10,000 breaks a second, and this interrupter was built by Brashear, an optician. The interrupter was delivered in January or February 1900, but experiments were not conducted until the fall of that year. To modulate his transmitter, he inserted a carbon microphone directly in series with the antenna lead. After many unsuccessful tries, transmission of speech over a distance of 1.5 km was finally achieved on 23 December 1900, between 15-metre masts located at Cobb Island, Maryland. A couple paragraphs later.... Fessenden's greatest radio communications successes happened in 1906. On 10 January, two-way transatlantic telegraphic communication was achieved -- another first – between Brant Rock, Massachusetts, and Macrihanish, Scotland. James C. Armor, Fessenden's chief assistant, was the operator at Macrihanish, and Fessenden himself was the operator at Brant Rock. End quote OK. There are some questions that may be easily taken from these paragraphs. When was the date of the first successful voice transmission? A. July 15, 1905 B. December 1, 1899 C. December 23, 1900 D. January 10, 1906 Some place you can look up the answer = C What was the distance of the first transmission? A. 1.5 Kilometers B. 1.5 miles C. Transatlantic D. 5 meters Some place you can look up the answer = A Okay. So which is the superior method? Depends what you mean by "superior". If someone who knows nothing about Fessenden discovers that there are only two Fessenden questions in the pool, he/she need only learn two simple facts ("first voice transmission date = 1900" and "first voice transmission distance = 1.5 km = about 1 mile". But if a question pool is not available, the person has to learn a whole lot more because there's no telling what Fessenden questions, or how many, will be on the test. If I were to voice my preferences, I would just as soon read a nice story about Mr. Fessenden than a dry question pool. But functionally the two are identical. Not really. Heck, I could write at least a dozen different questions from those paragraphs. Should the answers to the question pool be some deep hidden tome, not accessible to the public? Nope. The *exact questions* should be secret! But that's not going to happen any time soon, so why get worked up over it? As much as the two methods are pretty much the same, I would only agree with that if no one was allowed to study *any* reference material *at all*. Reading the two paragraphs gives you the *exact* same answers as looking at a question pool. Not really. If we know the exact Q&A in this hypothetical question pool, the whole story that started out like this: Professor Kintner, who was working for Fessenden at that time, designed an interrupter to give 10,000 breaks a second, and this interrupter was built by Brashear, an optician. The interrupter was delivered in January or February 1900, but experiments were not conducted until the fall of that year. To modulate his transmitter, he inserted a carbon microphone directly in series with the antenna lead. After many unsuccessful tries, transmission of speech over a distance of 1.5 km was finally achieved on 23 December 1900, between 15-metre masts located at Cobb Island, Maryland. A couple paragraphs later.... Fessenden's greatest radio communications successes happened in 1906. On 10 January, two-way transatlantic telegraphic communication was achieved -- another first – between Brant Rock, Massachusetts, and Macrihanish, Scotland. James C. Armor, Fessenden's chief assistant, was the operator at Macrihanish, and Fessenden himself was the operator at Brant Rock. End quote Boils down to this: transmission of speech over a distance of 1.5 km was finally achieved on 23 December 1900 I'll take having to study the second over having to study the first any day. Finally, I deliberately included this particular material and this specific question because of a current disagreement between to members of the group. Do you see Len admitting he's wrong, even when IEEE says so? 73 de Jim, N2EY |
