Introducing the FOUR BASES
⏱ 4 min
Concept: The FOUR BASES are four evaluation criteria—Unity, Support, Coherence, Sentence skills—used to assess and revise academic writing. Each BASE answers a different question about your draft.
Mechanism: When revising, you apply each BASE in turn. Ask: Does every sentence support the thesis? (Unity) Do claims have evidence and explanation? (Support) Is the order logical and are transitions clear? (Coherence) Are grammar and tone correct? (Sentence skills)
| Criterion | Meaning |
|---|---|
| Unity | Every sentence supports the thesis. |
| Support | Claims are backed by evidence and explanation. |
| Coherence | Ideas flow in logical order; transitions are clear. |
| Sentence skills | Grammar and word choice are accurate; tone is appropriate. |
Worked example: If a paragraph mentions "AI may help diagnostics" but then discusses education funding, that violates Unity—the second sentence does not support the thesis.
How success is measured
You choose the correct BASE and use the feedback to check why that criterion fits the scenario.
Instructor notes: Introduce Unity, Support, Coherence, and Sentence skills as shared revision vocabulary for the whole course. Use the MCQ analysis item to check recognition of criteria, not extended writing. Reserve deep application to the diagnostic and Week 2; avoid a full rubric workshop in this slot. This is a quick understanding check, not portfolio assessment.
