Frank E. Wargocki, WA3AYW found K9AAU's short article ("A New System for Learning Morse Code," April, 1969) very interesting. archive 
When I learned the Code afew years ago, it was by being exposed to the alphabet in groups unlike those suggested in the article; and it was necessary to suppress or unlearn some letters while being introduced to others. I am a nearly total cw operator and am always interested in improving my ear so after reading this article Irealized that I am one of those with the habit of deciding what the letter is before the character is finished. Consequently, it is often necessary to change my mind after the character is complete. and this takes up time so it is a definite impediment.
With this in mind, I took some practice with the intention of losing this habit. It took me very little time to realize that if I actively tried to stay a letter or two behind the sender, I could hear the complete character before I had to decide what it was. This immediately gave me at least a three word per minute increase in speed with a very accurate copy.
Copying behind the Sender is not a new idea by any means, but when this method is understood in light of Mr. Erwood's article, it can provide a springboard for someone like me who is stuck at a good, but not yet 20 wpm speed to gain the extra few words to upgrade.

How would you teach Morse code to a person? Probably you'd divide the characters into groups and send the same few signals repeatedly until learned – sending "missed" characters more frequently. A microcomputer can provide the same individualized introduction to Morse code.

Erwood's "A New System for Learning Morse Code" is a book that presents a novel approach to learning Morse code. The book was first published in 1969 and was written by William G. Pierpont under the pseudonym "Chuck" Erwood. The system presented in the book is based on the idea that Morse code can be learned most effectively by first learning the individual letters and then gradually building up to words and phrases. The book provides a series of exercises and drills that are designed to help the reader gradually master each letter of the code, before moving on to more complex exercises.
One of the key features of Erwood's system is the use of audio recordings that provide a continuous stream of code at a speed that gradually increases over time. This approach is intended to simulate real-world Morse code communication, and to help the learner develop the ability to copy and send code at increasingly high speeds.
Overall, Erwood's system has been praised for its effectiveness and has been used by many individuals to successfully learn Morse code. The book is available for purchase online and has also been made available for free on various websites. – chat.openai
