Week 1: How We Know the Past
Essential Question: How can we build a trustworthy account of the past when evidence is incomplete or disputed?
Mastery: All five daily lessons complete + all three principal assignments submitted + at least 80% on the ten-question objective quiz. Sub-80 attempts require review/corrections before retake. The constructed response is teacher-scored and belongs in the academic record.
Teacher Intent
This opening week teaches the method students will reuse throughout the course: distinguish evidence from inference, evaluate origin/audience/purpose/context, corroborate independent records, use spatial or quantitative evidence carefully, state uncertainty, and make claims no stronger than the evidence allows. The simulated town-meeting source set is a methods laboratory, not evidence about a real historical event.
Standards
- D1.5.9-12 — Determine source types useful to compelling and supporting questions.
- D2.His.1.9-12 — Evaluate historical context and circumstances.
- D3.1.9-12 — Evaluate origin, authority, structure, context, and corroborative value.
- D4.1.9-12 — Construct evidence-based arguments acknowledging counterclaims.
- RH.9-10.1 — Cite specific textual evidence.
- RH.9-10.7 — Integrate quantitative/technical and qualitative evidence.
- WHST.9-10.1 — Write discipline-specific arguments.
Five-Day Pacing
| Day | Core work | Mastery evidence |
|---|
| Monday | Evidence, inference, and limits of the historical record. Students sort statements into direct observation, source information, inference, and unsupported assertion. | Qualified claim + evidence/uncertainty ledger. |
| Tuesday | OPVL/source analysis and corroboration using two simulated eyewitness accounts plus a meeting record. | Assignment 1 + one corroborated and one uncorroborated claim. |
| Wednesday | Spatial evidence: map six observer positions and compare line of sight with reported details; organize source reliability in a matrix. | Assignment 2 + pattern/explanation/limitation statement. |
| Thursday | Claim-evidence-reasoning-counterclaim workshop. Students test a position about biased versus allegedly neutral sources. | Assignment 3 + revised claim after counterargument. |
| Friday | Five-step reliability audit, mastery quiz, constructed response, corrections/retake plan if needed. | 80%+ objective quiz + teacher-reviewed constructed response. |
Assignment Guidance
1 · Source Lab — Conflicting Eyewitness Accounts
20 points. Require OPVL, corroboration table, and a 150–250 word qualified claim. Accept multiple conclusions only when the evidence and reasoning support them.
Look for: origin and audience identified; at least two specific details; distinction between what the source shows and what the student infers; one limitation; one additional source that would help resolve uncertainty.
2 · Evidence Map & Reliability Matrix
20 points. Students map observer location and create a usefulness matrix. The map should be treated as evidence about position/visibility, not as proof of honesty or motive.
Look for: accurate labels, clear legend or key, observed pattern, plausible explanation, and explicit statement of what the visualization cannot prove.
3 · Evidence-Based Seminar or Argument
30 points. Prompt: Is an openly biased source necessarily less useful than a source that presents itself as neutral?
Look for: defensible thesis, three specific pieces of evidence from at least two source types, serious counterclaim, qualification, and conclusion proportional to the evidence. Score reasoning, not political or moral agreement.
Week 1 Mastery Quiz Key
Correct-answer distribution is intentionally balanced: A=2, B=3, C=3, D=2.
| # | Correct answer | Why |
|---|
| 1 | A · Primary source | Created during the period/event; still requires source evaluation. |
| 2 | B · Corroboration | Independent records are compared for agreement, contradiction, and uncertainty. |
| 3 | C · Conditions, values, and events shaping the source | That is contextualization. |
| 4 | D · The vote is better corroborated than the disputed motive | Evidence can support one part of a claim more strongly than another. |
| 5 | A · Analyze perspective rather than discard automatically | Bias affects evidentiary use; it does not erase value. |
| 6 | B · Three independent records support the time claim | The statement names evidence and makes a proportional conclusion. |
| 7 | C · Location/line of sight may shape observation | Spatial evidence tests visibility but not honesty or motive by itself. |
| 8 | D · Name uncertainty and additional evidence needed | Qualified claims prevent overstatement. |
| 9 | B · Purpose/audience reveal intended persuasion; facts still need checking | A persuasive source can be useful without being automatically factual. |
| 10 | C · Question → source/context → corroborate → qualified claim | This is the strongest complete inquiry sequence. |
Constructed Response · 5 points
Prompt: Using at least two specific ideas from this week, explain how a historian can build a trustworthy account when surviving evidence is incomplete or disputed. Distinguish evidence from inference and identify one limitation or uncertainty.
| Evidence | 2 pts · Uses at least two accurate Week 1 concepts or pieces of evidence. |
|---|
| Reasoning | 2 pts · Explains how the evidence/method strengthens reliability. |
|---|
| Accuracy & limits | 1 pt · Distinguishes inference from evidence and identifies a real uncertainty or needed source. |
|---|
Mastery workflow: Objective score below 80% → revisit relevant lesson/readings → complete error analysis → explain why missed choices were weak → retake. Preserve best objective score and attempt count.
Safeguards & Mentor Use
Archaemenes may question, explain, compare, or guide source analysis, but the mentor does not award quiz credit or replace evaluator judgment. Students may use verification/research tools to test claims only when they document what they checked and where the evidence came from. AI-generated citations or invented evidence receive no credit.
