With all of the experience learning Japanese that RTK users here (and also people who have used the AJATT method, Anki, iKnow, and so on) have, I am proposing a question: if you were given the opportunity to teach high school students, whose 1st language is English, how would you go about it?
My journey of learning Japanese has primarily been a rough one of trial-and-error. I began when I was about 8 years old with books like 'Japanese in 10 Minutes a Day' and listening to the Living Language Japanese CD set. Though the time I spent learning when I was young made sure that I retained a lot of essential phrases and had a decent handle on grammar, I understood little about particle words and did not understand the writing system. It all seemed so complex and bewildering at that age! After a year and a half or two, I sort of abandoned it until I was in high school (an independent study program), where I resumed my self-study of Japanese, and got credits for my work.
As a freshman, I learned the kana and about 200 kanji, through flash cards and writing down the characters repeatedly. Unaware of Heisig's 'Remembering the Kanji', I studied the radicals through NTC's fabulous kanji dictionary; understanding their meanings helped me to retain characters that would otherwise have confused me. I also started the Pimsleur series, which (while the speaking is slower than actual Japanese) helped my pronunciation immensely. I continued in this manner as a sophomore, adding on about another 150 kanji, though it was difficult for me to say where I was at progress-wise. Books like 'Barron's Japanese Grammar' and Naoko Chino's paricle word book deepened my understanding of how the language works.
Being out of school now, it is easier for me to go back and judge my progress. I know the kind of material you would expect to find in books like 'Japanese for Busy People', I know hiragana and katakana, and 500+ kanji (especially due to starting RTK). Going through programs like iKnow has helped refresh me on what I learned when I was 8 and 9, which was actually even more than I realized, and I have been able to steer many of my friends who are interested in learning Japanese on the right path, the path I wish I would have been able to take years ago. So many more resources are available to Japanese learners now!!
Because of my experience, my former high school accepted me as a Japanese workshop teacher last semester, and I'm on again this semester. I had been teaching from my own compiled materials (Yookoso, Japanese for Busy People, and other books I had mentioned above) and thought it was important for the students to fully understand the grammar and know how to carry on a basic conversation before delving into the writing system, which I plan to do this semester. I know this may be contrary to suggested methods, like starting with kanji, then kana, then the 10,000 sentences like with AJATT, but I was sure that it would be very discouraging for a high schooler interested in learning Japanese to start out with learning loads of kanji and not be able to say much of anything!! Anyhow, I want to take my class to a new, high-productivity level this year, how would you go about it RTK?

I'm going to try to address what was said here so far:
