Multisyllabic Decoding in a Sixth-Grade Word Study Block
At Ridgeview Middle School, the sixth-grade team reviews fall universal screening. In Ms. Alvarez's class of 24 students, 9 score between the 40th and 55th percentile on a word-reading measure. These students read 'signal' and 'picnic' accurately but misread 'signature' and 'diagnosis,' usually producing 'sig-na-ture' with a short a and giving 'diagnosis' equal stress on every syllable. Their spelling samples show 'medisin' for medicine, 'crueshal' for crucial, and 'presedure' for procedure. Reading comprehension scores are stronger than word-reading scores, and oral reading fluency is about 20 words per minute below the class median. The team has 25 minutes daily for word study and a district expectation to use the core curriculum, which includes a supplemental multisyllable decoding unit beginning in week 6. Ms. Alvarez wonders whether to wait for that unit or intervene now, and whether the 9 students should be grouped together for all literacy instruction.
1. What is the most likely locus of the 9 students' difficulty, and what specific evidence in the screening and spelling data supports that interpretation?
Read the worked answer
The pattern points to multisyllabic decoding involving syllable juncture, stress, and morphology, not a broad phonological deficit. The students read 'signal' and 'picnic' accurately, which shows they can handle common syllable patterns and closed syllables. Their errors appear when a base word is embedded in a longer derived word: 'signature' requires recognizing 'sign' plus a suffix and producing the reduced vowel in the final syllable, while 'diagnosis' requires appropriate stress placement and syllable division. Equal stress across syllables suggests they are not yet using stress and schwa patterns to organize longer words.
The spelling errors are consistent with this. 'Medisin' preserves the base 'medic-' but represents the schwa sound phonetically; 'crueshal' shows uncertainty about the spelling of the /ʃ/ sound; 'presedure' preserves the base 'procede/procedure' imperfectly. These are morphological spelling errors, not random phonetic guesses.
The comprehension scores being stronger than word reading is important: it suggests the bottleneck is recognizing words, not understanding language once words are read. Fluency being 20 words per minute below the median fits that explanation. Therefore the intervention should target syllable division, schwa and stress, and morphological spelling-not comprehension strategies. Waiting until week 6 would leave these students without targeted support for five to six weeks, and the core supplemental unit may not include the cumulative review and spelling linkage they need.
2. Design the 25-minute daily word study block for the next three weeks. Explain your grouping decision and the sequence of activities.

I would not group the 9 students together for all literacy instruction, because their comprehension is a relative strength and removing them from grade-level text discussion would narrow their access to meaning-making. Instead, I would keep the heterogeneous comprehension block and use a focused small-group word study during independent reading or station time, with the remaining students working on independent text response.
The 25-minute block should follow a predictable cycle. First, 5 minutes of review with previously taught words and a quick cumulative dictation. Second, 8 to 10 minutes of explicit instruction on one pattern per week: week 1, syllable division and open/closed syllables in words such as 'signal/signature'; week 2, schwa and stress in words such as 'medicine' and 'diagnosis'; week 3, morphological spelling with bases and suffixes, including 'crucial' and 'procedure.' Third, 7 to 8 minutes of guided practice in which students divide words, mark vowel sounds, build word families with the same base, and read the words in connected sentences. Fourth, 3 to 5 minutes of dictation and error correction.
The sequence moves from sound and syllable structure to meaning-based spelling, which matches the error pattern. I would begin now rather than wait for week 6 because the screening indicates a current need; when the supplemental unit begins, it can reinforce and extend this work. Materials should include words that transfer to social studies and science texts so the instruction does not remain a list of isolated items.
3. How should Ms. Alvarez monitor progress and decide whether to continue, modify, or exit the intervention?
Read the worked answer
Progress monitoring should measure the taught skill and transfer, not just comprehension. Every two weeks I would administer a brief 2-minute probe containing three sets of words: words with the taught pattern, untaught words that share the same base or syllable type, and a short connected passage for fluency. I would record both accuracy and the specific error type-for example, whether the student now reduces the final syllable in 'signature' or still assigns equal stress in 'diagnosis.'
A reasonable decision rule is that students should show improvement on the taught pattern and some transfer to untaught words across three consecutive probes; if accuracy remains flat after four to six weeks of explicit instruction, the team should examine whether the difficulty is broader, whether attendance or practice time is insufficient, or whether a more intensive intervention is warranted. If students master the pattern but do not transfer, the problem may be in the practice design, and I would add mixed review and application to content-area text.
I would also keep a classroom-based measure: a monthly oral reading sample from grade-level text and a spelling inventory. Exiting the group should depend on both the probe data and the students' ability to apply the skill in real reading, not only on the word list. The final decision should be made collaboratively with the team and documented so the next teacher knows what was taught and what worked.
