The DESE process is outlined on this page and here I will quote it:
ADSE/DESE -- A Five-Stage Method of Language Acquisition & Language LearningI have a feeling the above quote does not give us the complete process. First of all, it doesn't really say how much nor how long. How long should the audio be for stage one? How long would this stage last?
Stage 1: Select one audio tape suitable for your English level. Listen to it twice a day (one day off a week) until you can hear all the sounds of it. Don't try to translate and understand, comprehension is not important at this point, catching all the sounds is the goal.
Stage 2: Taking dictation of the whole passage sentence by sentence (not phrase by phrase or word by word). Looking up the English Dictionary (e.g. 'Collins COBUILD English Dictionary for Advanced Learners' or 'Longman Dictionary of Contemporary English') for the spelling of words you are not sure. Imitating the pronunciation and intonation, Reading the transcript aloud (recitation), you try to sound as much like the original as possible.
Stage 3: Writing down the definitions and the example sentences of the words you don't understand in Stage 2, you read them aloud. If there are any more words in Dictionary you still do not understand, you look them up and write them down, reading them aloud until you can understand all.
Stage 4: Select one video tape, VCD or DVD (Movie or TV Drama) without any model transcripts. Repeat the above Stages.
Stage 5: Going through an entire issue of an English newspaper printed in USA. (1) Read an article aloud (repeatedly). (2) Without looking, tell someone (or pretend to be telling someone) about what you have read. (3) Do dictionary work as needed. (4) One by One ...
In stage 2, for the spelling, what are you supposed to do about homonyms? If you don't understand the words yet, it won't be possible to pick the right homonym. It wouldn't even be possible to find the words in the dictionary either since the spelling patterns of English need to be learned before you can look anything up.
My main critique at this point is that every stage besides the first one looks like STUDY to me. Dictation is a lot of work and looking words up in a dictionary is tiring work. I thought this method was supposed to be based on enjoying the language. I would not enjoy all the work that this method prescribes.
I wonder what the results are like. If anybody can point me to any more info regarding this method, I would appreciate it. The only other description of it I found was written here.
