How can we build a trustworthy account when evidence is incomplete or disputed?
Work at your own pace. One day and one task at a time. Split a session whenever you need to; the day numbers describe an order, not a deadline.

Read · What does a record actually support?
Read the five short methods sections and Sources A–F in the source pack below. All records describe a fictional meeting; they are practice evidence, not an account of a real town.
Your goal: separate observation, reported information, inference and a claim. A trace becomes evidence when it helps answer a question.
Classify these statements: (1) Source A records a 12–8 vote. (2) Everyone in the town supported the proposal. (3) At least some participants may have been concerned about early work starts. Explain which sources support your decisions.

The tally of 20 adults is a recorded count. It does not establish the size or opinion of the town. “Everyone supported it” conflicts with a recorded 12–8 vote and exceeds the room’s scope.
Write · Your first evidence ledger
Make three entries under “What the record supports” and three under “What remains uncertain.” Cite the source letter. Finish with a short initial answer to the weekly question. Preserve it for comparison on Day 5.
View preserved first version
Check · Day 1 finish point
You have distinguished a record from an interpretation, identified uncertainty and preserved your starting claim. Stop here whenever you need to.
Read · Who created the evidence?
Reread A, B, C and F. Ask who created each record, when, for whom and for what purpose. Note that F borrows its vote count from A: those counts are not independent.
Choose two records. Identify one agreement, one difference and one missing piece. Explain whether their agreement is independent. Do not average conflicting accounts or assume that a biased account is useless.
See a model after trying
A records the vote; B independently recalls the proposed opening time. F repeats A’s count, so A and F do not establish two independent vote counts.
Write · Assignment 1: Source analysis
Write 150–250 words making a qualified claim about the meeting. Refer to at least two sources, explain their value and limits, and request one additional source that would improve your account. Keep your source-analysis chart with it.
Check · Day 2 finish point
Your claim has cited evidence, reasoning, a limitation and a useful additional-source request. Your saved assignment remains a draft until you prepare it for review.
Read · Location and limits
Use the supplied coordinate map. North is up, the screen follows x=6 from y=3 to y=7, and each label identifies a witness. This constructed map shows positions; it cannot prove hearing, attention, memory or motives.
Compare A and C’s positions and the screen. Trace a possible line of sight to the chair. Describe what the map shows, what it suggests and what further evidence is needed. Calculate the opposition share of the recorded vote (8 of 20), then explain why that fraction is not a survey of the town.
See a model after trying
8 ÷ 20 = 40% of the recorded voters. That says nothing by itself about nonattendees. Position and an obstruction can limit a possible view; they cannot prove what someone heard.
Write · Assignment 2: Map and reliability matrix
Keep a labeled map or coordinate record. For all six sources, describe proximity, purpose, independence, corroboration and one limitation. Add 120–200 words explaining a spatial pattern and what it cannot prove. Assess usefulness for a specific question, rather than ranking people as honest or dishonest.
Check · Day 3 finish point
Your record names a pattern, a plausible explanation and a limit. Your proportion includes its denominator.
Read · Make and challenge an argument
Revisit the methods reading and source pack. A openly official record, a private notebook and a persuasive letter each have purposes. Analyze purpose before deciding usefulness.
Question: Is an openly biased source necessarily less useful than a source that presents itself as neutral?
Practice · Build a reasoning bridge
Plan your claim, three specific references from at least two source types, reasoning and a serious counterclaim. State how your conclusion might change with new evidence.
See a model after trying
B’s concern about workers helps explain what Mira considered important. It cannot stand for every worker. A is useful for an official decision but omits participants’ reasons. Usefulness depends on the question.
Write · Assignment 3: Historical argument
Write a methods brief of about 350–500 words answering the question. Handwriting or supported oral work may be preserved with the same evidence criteria. Explain three references, address a counterclaim and qualify your conclusion. Keep a before/after excerpt of one meaningful revision.
Optional companion tools
Your source pack and writing fields contain everything required. Companion apps save separately; bring the relevant work back here.
Your argument answers the question, explains rather than lists evidence, considers the counterclaim and preserves a revision.
Read · Review the method
Revisit your saved first claim. Review the cycle: question → source and context → corroboration → spatial/data check → qualified conclusion. Keep the source pack available for the weekly open-book check.
Practice · Evidence audit
Check that your three assignments include the source chart, corroboration, map/matrix and argument. Decide whether a first claim needs a narrower scope or stronger evidence.
Write · Weekly check and constructed response
Use the course’s ten-question quiz and written response. The objective check requires 80%; the response is separately evaluated out of 5. A draft, checkbox or prepared submission does not award mastery.
If the objective result is below 80%, explain missed reasoning and practice before a retake. Written feedback may require a revision even when objective mastery is met.
Check · Review growth, then pause
Compare your Day 1 claim with your present reasoning. Cite one improvement and name one next goal. Ask your evaluator to review the assignments and written response before treating the week as mastered. There is no deadline to move to Week 2.
Evaluator assignment guidance: 20 points for source analysis, 20 for map/data reasoning, 30 for argument. Use the teacher guide for the detailed criteria.
Reading, six sources and meeting map
Classroom simulation: all people, records, dates and positions below are fictional and were created for this lesson. They support methods practice only.
Setting the Stage
Social studies begins with questions. Historians, geographers, economists, and civic researchers do not simply collect facts; they decide what evidence is relevant, test explanations, and communicate conclusions. Because the past cannot be rerun, every historical account depends on surviving traces such as letters, laws, artifacts, maps, photographs, oral histories, buildings, and statistical records.
People, Power, and Systems
Sources were created by people with purposes. A tax register records what officials wanted counted; a speech attempts to persuade; a diary may reveal private experience but only one person’s view. Researchers therefore ask who created a source, for whom, under what conditions, and with what possible limits. These questions do not automatically disqualify a source. They help determine what the source can reliably show.
Reading the Evidence
Corroboration is the practice of comparing sources. Two accounts may agree on the sequence of events while disagreeing about motives. An artifact may confirm that a technology existed but not prove how widely it was used. A historian builds a stronger conclusion by combining different kinds of evidence and explaining contradictions rather than hiding them.
Why It Matters
These habits matter beyond history. Citizens face claims in news reports, campaign messages, social media, advertisements, and artificial-intelligence outputs. The same habits—checking origin, context, evidence, and independent confirmation—help people make responsible decisions in the present.
Complete simulated source pack
Practice question: What decision did the meeting make, and what can we responsibly say about participants’ reactions? The map describes a 10-by-10-unit room; units are constructed, not measured historical distances.
Source A · Clerk’s minutes
Origin and audience: Written at 8:15 p.m., immediately after the meeting; intended as an official record. Clerk at (5,9).
At 7:35 the chair proposed opening the north footbridge at 8 a.m. instead of 6 a.m. for the next seven days while repairs were made. The recorded vote was 12 in favor and 8 against. Several voices called out after the vote. The chair ended the meeting at 8 p.m. No speakers’ reasons were entered.
Check the source’s scope
Records official decisions and counts; its omission of reasons does not establish that nobody gave a reason.
Source B · Mira’s notebook
Origin and audience: Written at 8:30 p.m. by a bakery worker seated at (4,7); a private account.
I heard the chair say the bridge would open at eight for a week because of repairs. A person near the west door called, “Some of us start before eight!” Other voices followed. I could not tell how many joined. I think the delay will make mornings harder for workers like me.
Check the source’s scope
Close to the chair and west door; interpretation about workers is a reasoned perspective, not proof of every worker’s opinion.
Source C · Leon’s letter
Origin and audience: Written the following morning by a repair volunteer seated at (8,2), behind a screen; sent to a neighbor.
I saw hands rise and heard cheering after the vote. I support careful repairs. Everyone seemed pleased that the bridge would be safer. I could not make out every word from the front.
Check the source’s scope
Supports a repair-focused perspective. The claim that everyone was pleased exceeds what this position or testimony can establish.
Source D · Door attendant’s tally
Origin and audience: Made during the meeting by Suri at (1,4) for room-capacity monitoring.
Twenty adults were recorded in the room when the vote was called. Three people stood near the west door afterward. This tally did not identify how they voted or why they stood there.
Check the source’s scope
Counts people and position at a specified time; cannot establish support, motives, or the entire town’s views.
Source E · Illustrator’s floor sketch
Origin and audience: Drawn at 7:30 p.m. by Toma at (2,2), before the vote, to document room layout.
The chair’s table was on the north side. A folding screen stood along x=6 from y=3 to y=7. Witness positions are shown on the supplied map. No vote outcome or conversation is recorded in this sketch.
Check the source’s scope
Useful for layout and possible lines of sight; a pre-vote drawing cannot independently establish what happened after the vote.
Source F · Nell’s community notice
Origin and audience: Written two days later by Nell at (9,7), who attended but used the clerk’s minutes for the vote count; intended to inform residents.
The bridge schedule proposal passed 12–8. The meeting ended at 8 p.m. Some residents raised concerns about early starts. The notice’s count comes from the clerk’s minutes; I did not make a separate count.
Check the source’s scope
Partly dependent on A. Repeating A’s count does not create an independent corroborating count.
The chair’s table is near A; the west door is near D. Coordinates are a constructed layout. Draw or describe a possible line of sight before making any inference.
