Ability to Use Source Materials
What the domain tests
Ability to Use Source Materials tests how well you evaluate, integrate, cite, and synthesize sources. Multiple-choice items may ask which source is most credible, which paraphrase is acceptable, how a quotation should be introduced, or what citation is required. Source-based writing rewards the same skills: accurate use of evidence and clear attribution.
Evaluating sources
Judge credibility by author credentials, publisher or peer review, publication date, evidence quality, and bias or purpose. Distinguish primary sources (raw data, eyewitness accounts, original documents) from secondary sources (interpretations, summaries). Currency matters more in fast-changing fields than in settled historical topics. Separate fact from inference and opinion, and watch for small or self-selected samples and for correlation presented as causation.
Integrating evidence
Introduce quotations with a signal phrase that names the source and, when useful, the source's authority. Quote only the words that matter, then explain how they support your point. Paraphrase by restating both the idea and the sentence structure in your own words; changing a few synonyms while keeping the original structure is patchwriting. Summarize when you need the gist rather than detail. Cite paraphrased ideas as well as direct quotations; common knowledge does not need a citation, but specific data and interpretations do.
Synthesis
Organize source-based writing by idea, not by source. Show relationships: Source A confirms Source B, Source C qualifies both, or Source D offers a rival explanation. A source-by-source list is summary, not synthesis.
Worked example
Source A, a district report, says later school start times raised attendance by 3 percent. Source B, a pediatric policy statement, explains that adolescent sleep cycles shift later. Synthesis: The district's attendance gain is consistent with the pediatric association's explanation that adolescent circadian rhythms shift later; together the sources suggest a mechanism and an observed outcome, though one district's single-year data cannot prove causation. This uses both sources, states their relationship, and notes a limit.
Traps that cost marks
- Quote dumping: a long quotation with no analysis.
- Patchwriting that keeps the original sentence structure.
- Citing direct quotations but not paraphrased ideas.
- Treating one testimonial or anecdote as representative evidence.
- Ignoring publication date, author bias, or sample size.
- Listing sources one after another without showing agreement, contrast, or contribution.
