Diagnosing Spelling Errors: Morphology, Phonology, or Dialect?
During the first month of seventh grade, a teacher collects 50-word writing samples and a dictated sentence list from 26 students (6 multilingual learners and 4 students with identified language impairments). She tallies errors: 38% of past-tense verbs omit -ed ('walk' for 'walked'); 22% spell 'went' as 'whent'; 15% confuse 'their,' 'there,' and 'they're'; 9% write 'aks' for 'ask'; and 6% write 'childs' for 'children.' A colleague recommends a packaged phonics program; the reading coach suggests morphology mini-lessons; the ESL teacher suggests explicit dialect awareness. The teacher has 15 minutes daily for word study and must decide which pattern to address first, without treating dialect differences as deficits. She also has not yet separated errors that occur in speech from errors that occur only in writing.
1. Classify the five error patterns by linguistic system and explain which one should be the instructional priority.

The patterns are not all the same kind of problem. Omission of -ed is primarily morphological because it marks past tense, though in some dialects it also reflects phonological cluster reduction. 'Whent' for 'went' is phonological and orthographic, likely an overgeneralization of the 'wh' spelling pattern. 'Their/there/they're' is orthographic and meaning-based; homophones require syntactic context. 'Aks' for 'ask' is dialect variation through metathesis, not a developmental spelling error. 'Childs' is morphological overgeneralization of the regular plural -s. The priority should be -ed, because it is high-frequency in academic writing and affects tense clarity across subjects. But the teacher must first check whether the omissions occur in speech, in writing, or both. If only in writing, the issue is spelling and sentence-level editing; if in speech, dialect influence is likely. The 38% figure is large enough to justify a two-week focus, with 'childs' and homophones as secondary targets.
2. How should the teacher respond to the 'aks' and -ed patterns so as not to pathologize African American English while still teaching Edited American English?

The teacher should use contrastive analysis rather than correction. For 'aks,' she can note that many English speakers say 'aks' and that it is a regular dialect pronunciation, then teach when Edited American English 'ask' is expected in formal writing and oral presentations. Students should not be interrupted or shamed during discussion. For -ed, the teacher can compare sentences in African American English and Edited American English-for example, 'He walk to school yesterday' versus 'He walked to school yesterday'-and ask students to describe the difference in meaning and context, not to rank one variety as better. The goal is code-switching: adding a written register to students' existing repertoire. The teacher should also re-examine her error tally. If -ed omissions appear only in the writing of African American English speakers, treating them as a universal skill deficit is inaccurate and may reflect a mismatch between home language and school expectations.
3. Design a two-week, 15-minute daily sequence focused on the priority pattern, and explain how you would know it worked.

Days 1-2: explicit contrast of past-tense meaning with and without -ed; students sort regular and irregular verbs. Days 3-4: word-building with base words and -ed, including spelling rules such as stop/stopped and hope/hoped. Days 5-6: sentence-level editing of teacher-written paragraphs containing six to eight -ed errors; students explain each correction. Days 7-8: short dictation and timed writing, then self-editing with a checklist. Days 9-10: apply the pattern to a content-area paragraph, such as a science observation, and peer review. Assessment: collect a 50-word writing sample before and after, count accurate past-tense verbs in obligatory contexts, and compare. A reasonable decision rule is to reteach with more phonological support if accuracy does not improve by at least 30%. Also monitor whether students can explain the difference between dialect speech and formal writing, because that is the transferable understanding.
