- Historians make inferences about the past based on evidence from primary and secondary sources, recognizing that historical accounts are interpretations influenced by context rather than purely factual records. - Our understanding of events like the Boston Massacre and figures involved like Crispus Attucks has changed over time through expanding historical analysis and additional sources of information. - Wikipedia in particular has evolved our shared knowledge about the Boston Massacre through collaborative contributions from many editors that have greatly expanded the initial article while still singling out Crispus Attucks as the first casualty.

2. How do we know about the past?

3. Evidence “The concept of evidence is central to history because it is only through the use of evidence that history becomes possible.” (How people learn, Lee, 2005, p. 54).

4. Evidence Misconceptions might include The assumption that history is just known The assumption that primary sources should not contradict or disagree That biased sources are “untrue” That historical interpretation is solely based on factual evidence

5. Work of historians Historians make inferences “Historians are not simply forced to choose between two reports, but can work out their own picture, which may differ from both. With this understanding goes the recognition that we can know things about the past that no witness has reported” (Lee, 2005, p. 58)

Back to the Boston Massacre – look at the original WP article, as it was first created(History --> view earliest)http://en.wikipedia.org/w/index.php?title=Boston_Massacre&oldid=203484 Posted at11:02 am, 8 September 2002 (there were 3 other edits that same day, all in about 20 minutes from the initial draft)

16. Initial text 11:02, 8 September 2002 12.232.19.38 (talk) The Boston Massacre occurred 5 March 1770AD. This was one of the events that helped spark the American Revolution. In an event much like what would happen over 200 years later at Kent State, a mob of men began taunting armed soldiers. After some of the men began throwing ice at the British soldiers, eventually the soldiers fired back. In this action, 5 Americans died, including one Crispus Attucks, the first known African-American Casualty of the American Revolution. Six more were injured. The event was immortalized by an engraver named Paul Revere. In a post-massacre trial, 6 soldiers were found non-guilty, and 2 more-- the only two proven to have fired-- were found guilty of manslaughter. John Adams acted as defense attorney.

19. How does the structure of Wikipedia help us understand the discipline of history Focus on Crispus Attucks. He gets singled out by name in both the textbook and the first version of the Wikepedia article, as well as all of the 1657 versions that followed.

21. Was Attucks singled out in Revere's print? Text below the engraving “Unhappy Boston! see thy Sons deplore, Thy hallowed Walks besmeared with guiltless Gore." Also listed are the "unhappy Sufferers" Saml Gray, Saml Maverick, James Caldwell, Crispus Attucks, and Patrick Carr (killed) and it is noted that there were "Six wounded; two of them (Christr Monk & John Clark) Mortally.”

22. How did we get to the point where Attucks is the only one of the six that gets attention? Wikipedia article on Crispus Attucks actually gives us a lot to go onhttp://en.wikipedia.org/wiki/Crispus_Attucks

23. Wikipedia as a field of history?
