Almost 700 children were screened to identify 144 1st graders at risk for handwriting problems who were randomly assigned to 1 of 6 treatment conditions. Treatment was delivered to groups of 3 that met twice a week in 20-min sessions until they completed 24 lessons. Five groups received 10 min of different kinds of handwriting instruction. The contact control group received 10 min of phonological awareness training. All 6 groups composed and shared their writing for 10 min. Converging evidence across multiple measures showed that combining numbered arrows and memory retrieval was the most effective treatment for improving both handwriting and compositional fluency (composing with time limits). Thus instruction aimed at improving transcription transfers to improved text generation in beginning writers.

Third graders with low compositional fluency (N ϭ 96) were randomly assigned to 4 time-equated treatments in an instructional experiment (24 lessons over 4 months): spelling (alphabetic principle plus its alternations), composing (reflective discussion plus teacher scaffolding), combined spelling (alphabetic principle) plus composing (teacher scaffolding), and treated control (writing practice, no instruction). All treatments increased compositional fluency. Spelling and combined spelling plus composing were most effective for word-specific spelling (taught words). Teaching alternations improved phonological decoding and transferred to spelling in composing. Composing and combined spelling plus composing were most effective for persuasive essay writing. Only combined spelling plus composing increased both spelling and composing. Results are related to the simple view of writing that integrates diverse theoretical traditions and instructional practices.

Structural equation modeling evaluated the contribution of phonological, orthographic, morphological, and oral vocabulary factors to word reading, spelling, and reading comprehension outcomes in 98 2nd graders at risk for passing state standards in reading and to those same outcomes plus composing in 97 4th graders at risk for passing state standards in writing. For 2nd-grade children, morphology contributed uniquely to reading comprehension, and oral vocabulary and orthography contributed uniquely to word reading. For 4th-grade children, morphology and oral vocabulary did not contribute uniquely to any outcomes, but morphology and word reading were correlated, and orthography and phonology contributed uniquely to decoding words with affixes. Fourth graders are still learning to coordinate orthographic, phonological, and morphological cues in written words.

Poor spellers in 2nd grade (« = 128) participated in 24 20-min sessions that included (a) direct instruction in the alphabet principle (most frequent phoneme-spelling connections); (b) modeling of different approaches, singly and in combination, for developing connections between spoken and written words for 48 words ordered by sound-spelling predictability; and (c) practice in composing. Results of this multilayered intervention showed that (a) more than 1 way of developing sound-spelling connections is effective in teaching spelling but that after training in the alphabet principle, combining whole word and onset-rime training is most effective in achieving transfer of the alphabet principle across word contexts; (b) functional spelling units of not only a single letter but also 2 or more letters are important in beginning spelling; and (c) training in spelling transfers to composition and word recognition.
