What is the partial alphabetic stage?
Likewise, what is alphabetic stage?
The four phases are: Pre-alphabetic phase: students read words by memorizing their visual features or guessing words from their context. Partial-alphabetic phase: students recognize some letters of the alphabet and can use them together with context to remember words by sight.
Thereof, what is consolidated alphabetic stage?
In the consolidated alphabetic phase of decoding, the sequence of letters in a word becomes salient. A person in this phase groups common patterns of letters and sounds as units. This allows her to decode multi-syllable, novel, and nonsense words by analogy. A person in this phase decodes many words by sight.
Children have to learn such constraints; they aren't born knowing them. Thus, at the first (logographic) stage of learning how to spell, many children know words as 'wholes', and might spell them forwards or backwards, because they haven't as yet developed a set of alphabetic or orthographic spelling rules.
