I had that trust issue too, but this phrase by imercon has proven to be sooooooo true...
it is a process that must be trusted and faithfully applied and it will yield results
Dictation is harder than spelling, and the way spelling is done in HOD is a stepping stone for dictation. The CM style lessons planned with the spelling words in the LA box of the guide are very effective. I know we probably all grew up doing spelling lists, by studying them and taking a test, but the way the plans are written in the HOD guide is totally different. It applies the idea of the mind being like a camera taking a "picture" of the word each time it sees it.
So for HOD spelling - Day 1 always has the child look at one word written in black on an index card. Study it, and when child says he is ready, take the card away and child writes just that one word on his marker board. If he misses it, right away, erase it and show him the card again (to erase that incorrect "picture" in his mind immediately), and when he says he is ready, take the card away until he writes it correctly. Then, Day 2's spelling has you just saying the word, using it in a sentence. The child tries to write the word from memory, but if he misses it, erase it immediately to erase the incorrect "picture" and show him the index card, allowing him to study it as he did on Day 1 and then write it. On Day 3, you only pick 3 words the child needs to practice the most. One word at a time, the child should use the word in a sentence orally, as you write the sentence on markerboard for him. Then, the child looks at the markerboard to copy the sentence on paper. You help the child correct any mistakes then. Finally, on Day 4, you say the word, use it in a sentence, and child tries to write it correctly. This time, if it is missed, erase it, and show the child the index card again. Have him fix it on his paper, and while looking at the index card, do the activity to review missed words (it rotates each week).
Many skills are learned in this method of spelling, rather than a child just studying a list and taking a test at the end. This method of spelling provides an important foundation for dictation the following year. You can see that using it in a sentence, copywork of sentences, studying a word and having it taken away then, fixing errors, etc. all prepare dc to do dictation the following year. My ds had speech for several years as a young child having been quite premature, and yet has managed to thrive with HOD's spelling/dictation plans using CM style methods. I highly recommend giving it a patient try and then I am certain you will see the fruits of it given time!

I'm a former user of Spelling Power, and R & S spelling, as well as other programs - I've found CM's methods have been the most successful and produced the most carryover to dc's own writing - which is the core reason we're studying spelling in the first place

. This took me awhile to come to this consensus - but now with my second child, I'm totally on board with it - and it shows in his excellent spelling already.

By the time our third one's doing it, I'll be a real pro!
